important part of the quality assessment and the dating of (archaeological) wood samples. It provides quantitative data about the whole anatomical ring structure, which can be used, for example, to measure the impact of the fluctuating environment on the tree growth, for the dendrochronological analysis of archaeological wooden artefacts and to estimate the wood mechanical properties. Despite advances in computer vision and edge recognition algorithms, detection and counting of annual rings are still limited to 2D datasets and performed in most cases manually, which is a time consuming, tedious task and depends strongly on the operator’s experience. This work presents an image processing approach to detect the whole 3D tree-ring structure directly from X-ray computed tomography imaging data. The approach relies on a modified Canny edge detection algorithm, which captures fully connected tree-ring edges throughout the measured image stack and is validated on X-ray computed tomography data taken from six wood species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ring%20recognition" title="ring recognition">ring recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20detection" title=" edge detection"> edge detection</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20computed%20tomography" title=" X-ray computed tomography"> X-ray computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=dendrochronology" title=" dendrochronology"> dendrochronology</a> </p> <a href="https://publications.waset.org/abstracts/130684/image-processing-approach-for-detection-of-three-dimensional-tree-rings-from-x-ray-computed-tomography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130684.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Unbranched, Saturated, Carboxylic Esters as Phase-Change Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anastasia%20Stamatiou">Anastasia Stamatiou</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Obermeyer"> Melissa Obermeyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Ludger%20J.%20Fischer"> Ludger J.

Important thermophysical properties are gathered both by means of literature research as well as by experimental measurements. Additionally, esters are critically evaluated against other common phase-change materials in terms of their environmental impact and their economic potential. The experimental investigations are performed for eleven selected ester samples with a focus on the determination of their melting temperature and their enthalpy of fusion using differential scanning calorimetry. Transient Hot Bridge was used to determine the thermal conductivity of the liquid samples while thermogravimetric analysis was employed for the evaluation of the 5% weight loss temperature as well as of the decomposition temperature of the non-volatile samples. Both experimental results and literature data reveal the high potential of esters as phase-change materials. Their good thermal and environmental properties as well as the possibility for production from natural sources (e.g. vegetable oils) render esters as very promising for future storage applications. A particularly high short term application potential of esters could lie in low temperature storage applications where the main alternative is using salt hydrates as phase-change material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esters" title="esters">esters</a>, <a href="https://publications.waset.org/abstracts/search?q=phase-change%20materials" title=" phase-change materials"> phase-change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20heat%20storage" title=" latent heat storage"> latent heat storage</a> </p> <a href="https://publications.waset.org/abstracts/63849/unbranched-saturated-carboxylic-esters-as-phase-change-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63849.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">415</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Experimental Design and Optimization of Diesel Oil Desulfurization Process by Adsorption Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Firoz%20Kalam">M.

The investigation was considered for diesel oil samples after batch adsorption process using powdered activated carbon. Batch distillation process was applied to all treated diesel oil samples for separation of the solid-liquid mixture. The diesel oil properties were studied to observe the impact of adsorptive desulfurization process on fuel quality. Results showed that the best cetane number for desulfurized diesel oil was found at the best-operating conditions 60℃, 10g activated carbon and 180 minute contact time. The best-desulfurized diesel oil cetane number was obtained around 51 while the cetane number of untreated diesel oil was 34. Results also showed that the calculated cetane number increases as the operating temperature and amounts of adsorbent increases. This behavior was same for other diesel oil properties such as aniline point, diesel index, cetane index and density. The best value for all the fuel properties was found at same operating conditions mentioned above. Thus, it can be concluded that adsorptive desulfurization using powdered activated carbon as adsorbent had significantly improved the fuel quality of diesel oil by reducing aromatic contents of diesel oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=desulfurization" title=" desulfurization"> desulfurization</a>, <a href="https://publications.waset.org/abstracts/search?q=diesel%20oil" title=" diesel oil"> diesel oil</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20quality" title=" fuel quality"> fuel quality</a> </p> <a href="https://publications.waset.org/abstracts/84409/improvement-of-diesel-oil-properties-by-batch-adsorption-and-simple-distillation-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84409.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Distorted Document Images Dataset for Text Detection and Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilia%20Zharikov">Ilia Zharikov</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Nikitin"> Philipp Nikitin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilia%20Vasiliev"> Ilia Vasiliev</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Dokholyan"> Vladimir Dokholyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the increasing popularity of document analysis and recognition systems, text detection (TD) and optical character recognition (OCR) in document images become challenging tasks. However, according to our best knowledge, no publicly available datasets for these particular problems exist. In this paper, we introduce a Distorted Document Images dataset (DDI-100) and provide a detailed analysis of the DDI-100 in its current state. To create the dataset we collected 7000 unique document pages, and extend it by applying different types of distortions and geometric transformations. In total, DDI-100 contains more than 100,000 document images together with binary text masks, text and character locations in terms of bounding boxes. We also present an analysis of several state-of-the-art TD and OCR approaches on the presented dataset. Lastly, we demonstrate the usefulness of DDI-100 to improve accuracy and stability of the considered TD and OCR models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=document%20analysis" title="document analysis">document analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20dataset" title=" open dataset"> open dataset</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20character%20recognition" title=" optical character recognition"> optical character recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=text%20detection" title=" text detection"> text detection</a> </p> <a href="https://publications.waset.org/abstracts/106148/distorted-document-images-dataset-for-text-detection-and-recognition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106148.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Enhancing Rural Agricultural Value Chains through Electric Mobility Services in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clemens%20Pizzinini">Clemens Pizzinini</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Rosner"> Philipp Rosner</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Ziegler"> David Ziegler</a>, <a href="https://publications.waset.org/abstracts/search?q=Markus%20Lienkamp"> Markus Lienkamp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transportation is a constitutional part of most supply and value chains in modern economies.

Alternative heat treatment processes, such as contact heating, have been developed to improve the efficiency of this process. However, contact heating of the steel sheets often results in cracking within the Al-Si-coated layer. Therefore, this paper will address the development of alternative coating compositions based on Al-Si-X, suitable for contact heating. For this purpose, robot-assisted thermal arc spray was applied to coat the high-strength steel sheets. This ensured high reproducibility as well as effectiveness. The influence of the coating parameters and the variation of the nozzle geometry on the microstructure of the developed coatings will be discussed. Finally, the surface and mechanical properties after contact heating and press hardening will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=press%20hardening" title="press hardening">press hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20stamping" title=" hot stamping"> hot stamping</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20spraying" title=" thermal spraying"> thermal spraying</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20spraying" title=" arc spraying"> arc spraying</a>, <a href="https://publications.waset.org/abstracts/search?q=coating%20compositions" title=" coating compositions"> coating compositions</a> </p> <a href="https://publications.waset.org/abstracts/159998/alternative-coating-compositions-by-thermal-arc-spraying-to-improve-the-contact-heat-treatment-in-press-hardening" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159998.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Prioritization in Modern Portfolio Management - An Action Design Research Approach to Method Development for Scaled Agility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jan-Philipp%20Schiele">Jan-Philipp Schiele</a>, <a href="https://publications.waset.org/abstracts/search?q=Karsten%20Schlinkmeier"> Karsten Schlinkmeier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Allocation of scarce resources is a core process of traditional project portfolio management.

The prevailing framework SAFe offers Weightest Shortest Job First (WSJF) as a prioritization technique, butestablished companies are still looking for methodical adaptions to apply WSJF for prioritization in portfolios in a more goal-oriented way and aligned for their needs in practice. In this paper, the relevant problem of prioritization in portfolios is conceptualized from the perspective of coordination and related mechanisms to support resource allocation. Further, an Action Design Research (ADR) project with case studies in a finance company is outlined to develop a practically applicable yet scientifically sound prioritization method based on coordination theory. The ADR project will be flanked by consortium research with various practitioners from the financial and insurance industry. Preliminary design requirements indicate that the use of a feedback loop leads to better team and executive level coordination in the prioritization process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scaled%20agility" title="scaled agility">scaled agility</a>, <a href="https://publications.waset.org/abstracts/search?q=portfolio%20management" title=" portfolio management"> portfolio management</a>, <a href="https://publications.waset.org/abstracts/search?q=prioritization" title=" prioritization"> prioritization</a>, <a href="https://publications.waset.org/abstracts/search?q=business-IT%20alignment" title=" business-IT alignment"> business-IT alignment</a> </p> <a href="https://publications.waset.org/abstracts/142911/prioritization-in-modern-portfolio-management-an-action-design-research-approach-to-method-development-for-scaled-agility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Analysing Techniques for Fusing Multimodal Data in Predictive Scenarios Using Convolutional Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Ruf">Philipp Ruf</a>, <a href="https://publications.waset.org/abstracts/search?q=Massiwa%20Chabbi"> Massiwa Chabbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Reich"> Christoph Reich</a>, <a href="https://publications.waset.org/abstracts/search?q=Djaffar%20Ould-Abdeslam"> Djaffar Ould-Abdeslam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, convolutional neural networks (CNN) have demonstrated high performance in image analysis, but oftentimes, there is only structured data available regarding a specific problem. By interpreting structured data as images, CNNs can effectively learn and extract valuable insights from tabular data, leading to improved predictive accuracy and uncovering hidden patterns that may not be apparent in traditional structured data analysis. In applying a single neural network for analyzing multimodal data, e.g., both structured and unstructured information, significant advantages in terms of time complexity and energy efficiency can be achieved. Converting structured data into images and merging them with existing visual material offers a promising solution for applying CNN in multimodal datasets, as they often occur in a medical context. By employing suitable preprocessing techniques, structured data is transformed into image representations, where the respective features are expressed as different formations of colors and shapes. In an additional step, these representations are fused with existing images to incorporate both types of information. This final image is finally analyzed using a CNN. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CNN" title="CNN">CNN</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=tabular%20data" title=" tabular data"> tabular data</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20dataset" title=" mixed dataset"> mixed dataset</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20transformation" title=" data transformation"> data transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodal%20fusion" title=" multimodal fusion"> multimodal fusion</a> </p> <a href="https://publications.waset.org/abstracts/171840/analysing-techniques-for-fusing-multimodal-data-in-predictive-scenarios-using-convolutional-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171840.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Automated Testing of Workshop Robot Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arne%20Hitzmann">Arne Hitzmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Wentscher"> Philipp Wentscher</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Gabel"> Alexander Gabel</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinhard%20Gerndt"> Reinhard Gerndt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autonomous mobile robots can be found in a wide field of applications. Their types range from household robots over workshop robots to autonomous cars and many more. All of them undergo a number of testing steps during development, production and maintenance. This paper describes an approach to improve testing of robot behavior. It was inspired by the RoboCup @work competition that itself reflects a robotics benchmark for industrial robotics. There, scaled down versions of mobile industrial robots have to navigate through a workshop-like environment or operation area and have to perform tasks of manipulating and transporting work pieces. This paper will introduce an approach of automated vision-based testing of the behavior of the so called youBot robot, which is the most widely used robot platform in the RoboCup @work competition. The proposed system allows automated testing of multiple tries of the robot to perform a specific missions and it allows for the flexibility of the robot, e.g. selecting different paths between two tasks within a mission. The approach is based on a multi-camera setup using, off the shelf cameras and optical markers. It has been applied for test-driven development (TDD) and maintenance-like verification of the robot behavior and performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supervisory%20control" title="supervisory control">supervisory control</a>, <a href="https://publications.waset.org/abstracts/search?q=testing" title=" testing"> testing</a>, <a href="https://publications.waset.org/abstracts/search?q=markers" title=" markers"> markers</a>, <a href="https://publications.waset.org/abstracts/search?q=mono%20vision" title=" mono vision"> mono vision</a>, <a href="https://publications.waset.org/abstracts/search?q=automation" title=" automation"> automation</a> </p> <a href="https://publications.waset.org/abstracts/8364/automated-testing-of-workshop-robot-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8364.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">377</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Identified Transcription Factors and Gene Regulation in Scient Biosynthesis in Ophrys Orchids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chengwei%20Wang">Chengwei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuqing%20Xu"> Shuqing Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20M.%20Schl%C3%BCter"> Philipp M.

Therefore, floral traits associated with pollinator attraction, especially scent, are suitable models for investigating the molecular basis of adaption, speciation, and evolution. Within the two Ophrys species groups: O. sphegodes (S) and O. fusca (F), pollinator shifts among the same insect species have taken place. Preliminary data suggest that they involve a comparable hydrocarbon profile in their scent, which is mainly composed of alkanes and alkenes. Genes encoding stearoyl-acyl carrier protein desaturases (SAD) involved in alkene biosynthesis have been identified in the S group. This study aims to investigate the control and parallel evolution of ecologically significant alkene production in Ophrys. Owing to the central role those SAD genes play in determining positioning of the alkene double-bonds, a detailed understanding of their functional mechanism and of regulatory aspects is of utmost importance. We have identified 5 transcription factors potentially related to SAD expression in O. sphegodes which belong to the MYB, GTE, WRKY, and MADS families. Ultimately, our results will contribute to understanding genes important in the regulatory control of floral scent synthesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=floral%20traits" title="floral traits">floral traits</a>, <a href="https://publications.waset.org/abstracts/search?q=transcription%20factors" title=" transcription factors"> transcription factors</a>, <a href="https://publications.waset.org/abstracts/search?q=biosynthesis" title=" biosynthesis"> biosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20evolution" title=" parallel evolution"> parallel evolution</a> </p> <a href="https://publications.waset.org/abstracts/165903/identified-transcription-factors-and-gene-regulation-in-scient-biosynthesis-in-ophrys-orchids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165903.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> The Exercise of Deliberative Democracy on Public Administrations Agencies' Decisions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Filho">Mauricio Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Carina%20Castro"> Carina Castro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The object of this project is to analyze long-time public agents that passed through several governments and see themselves in the position of having to deliberate with new agents, recently settled in the public administration. For theoretical ends, internal deliberation is understood as the one practiced on the public administration agencies, without any direct participation from the general public in the process. The assumption is: agents with longer periods of public service tend to step away from momentary political discussions that guide the current administration and seek to concentrate on institutionalized routines and procedures, making the most politically aligned individuals with the current government deliberate with less "passion" and more exchanging of knowledge and information. The theoretical framework of this research is institutionalism, which is guided by a more pragmatic view, facing the fluidity of reality in ways showing the multiple relations between agents and their respective institutions. The critical aspirations of this project rest on the works of professors Cass Sunstein, Adrian Vermeule, Philipp Pettit and in literature from both institutional theory and economic analysis of law, greatly influenced by the Chicago Law School. Methodologically, the paper is a theoretical review and pretends to be unfolded, in a future moment, in empirical tests for verification. This work has as its main analytical tool the appeal to theoretical and doctrinaire areas from the Juridical Sciences, by adopting the deductive and analytical method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=institutions" title="institutions">institutions</a>, <a href="https://publications.waset.org/abstracts/search?q=state" title=" state"> state</a>, <a href="https://publications.waset.org/abstracts/search?q=law" title=" law"> law</a>, <a href="https://publications.waset.org/abstracts/search?q=agencies" title=" agencies"> agencies</a> </p> <a href="https://publications.waset.org/abstracts/64374/the-exercise-of-deliberative-democracy-on-public-administrations-agencies-decisions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Determination of Biomolecular Interactions Using Microscale Thermophoresis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lynn%20Lehmann">Lynn Lehmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinorah%20Leyva"> Dinorah Leyva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lazic"> Ana Lazic</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Duhr"> Stefan Duhr</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Baaske"> Philipp Baaske</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Characterization of biomolecular interactions, such as protein-protein, protein-nucleic acid or protein-small molecule, provides critical insights into cellular processes and is essential for the development of drug diagnostics and therapeutics. Here we present a novel, label-free, and tether-free technology to analyze picomolar to millimolar affinities of biomolecular interactions by Microscale Thermophoresis (MST). The entropy of the hydration shell surrounding molecules determines thermophoretic movement. MST exploits this principle by measuring interactions using optically generated temperature gradients. MST detects changes in the size, charge and hydration shell of molecules and measures biomolecule interactions under close-to-native conditions: immobilization-free and in bioliquids of choice, including cell lysates and blood serum. Thus, MST measures interactions under close-to-native conditions, and without laborious sample purification. We demonstrate how MST determines the picomolar affinities of antibody::antigen interactions, and protein::protein interactions measured from directly from cell lysates. MST assays are highly adaptable to fit to the diverse requirements of different and complex biomolecules. NanoTemper´s unique technology is ideal for studies requiring flexibility and sensitivity at the experimental scale, making MST suitable for basic research investigations and pharmaceutical applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biochemistry" title="biochemistry">biochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=biophysics" title=" biophysics"> biophysics</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20interactions" title=" molecular interactions"> molecular interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20techniques" title=" quantitative techniques"> quantitative techniques</a> </p> <a href="https://publications.waset.org/abstracts/27726/determination-of-biomolecular-interactions-using-microscale-thermophoresis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27726.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">523</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Fast Generation of High-Performance Driveshafts: A Digital Approach to Automated Linked Topology and Design Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Willi%20Zschiebsch">Willi Zschiebsch</a>, <a href="https://publications.waset.org/abstracts/search?q=Alrik%20Dargel"> Alrik Dargel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Spitzer"> Sebastian Spitzer</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Johst"> Philipp Johst</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20B%C3%B6hm"> Robert Böhm</a>, <a href="https://publications.waset.org/abstracts/search?q=Niels%20Modler"> Niels Modler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we investigate an approach that digitally links individual development process steps by using the drive shaft of an aircraft engine as a representative example of a fiber polymer composite. Such high-performance, lightweight composite structures have many adjustable parameters that influence the mechanical properties. Only a combination of optimal parameter values can lead to energy efficient lightweight structures. The development tools required for the Engineering Design Process (EDP) are often isolated solutions, and their compatibility with each other is limited. A digital framework is presented in this study, which allows individual specialised tools to be linked via the generated data in such a way that automated optimization across programs becomes possible. This is demonstrated using the example of linking geometry generation with numerical structural analysis. The proposed digital framework for automated design optimization demonstrates the feasibility of developing a complete digital approach to design optimization. The methodology shows promising potential for achieving optimal solutions in terms of mass, material utilization, eigenfrequency, and deformation under lateral load with less development effort. The development of such a framework is an important step towards promoting a more efficient design approach that can lead to stable and balanced results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20linked%20process" title="digital linked process">digital linked process</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=CFRP" title=" CFRP"> CFRP</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-objective" title=" multi-objective"> multi-objective</a>, <a href="https://publications.waset.org/abstracts/search?q=EDP" title=" EDP"> EDP</a>, <a href="https://publications.waset.org/abstracts/search?q=NSGA-2" title=" NSGA-2"> NSGA-2</a>, <a href="https://publications.waset.org/abstracts/search?q=NSGA-3" title=" NSGA-3"> NSGA-3</a>, <a href="https://publications.waset.org/abstracts/search?q=TPE" title=" TPE"> TPE</a> </p> <a href="https://publications.waset.org/abstracts/155897/fast-generation-of-high-performance-driveshafts-a-digital-approach-to-automated-linked-topology-and-design-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Analysis of the Cutting Force with Ultrasonic Assisted Manufacturing of Steel (S235JR)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Zopf">Philipp Zopf</a>, <a href="https://publications.waset.org/abstracts/search?q=Franz%20Haas"> Franz Haas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Manufacturing of very hard and refractory materials like ceramics, glass or carbide poses particular challenges on tools and machines. The company Sauer GmbH developed especially for this application area ultrasonic tool holders working in a frequency range from 15 to 60 kHz and superimpose the common tool movement in the vertical axis. This technique causes a structural weakening in the contact area and facilitates the machining. The possibility of the force reduction for these special materials especially in drilling of carbide with diamond tools up to 30 percent made the authors try to expand the application range of this method. To make the results evaluable, the authors decide to start with existing processes in which the positive influence of the ultrasonic assistance is proven to understand the mechanism. The comparison of a grinding process the Institute use to machine materials mentioned in the beginning and steel could not be more different. In the first case, the authors use tools with geometrically undefined edges. In the second case, the edges are geometrically defined. To get valid results of the tests, the authors decide to investigate two manufacturing methods, drilling and milling. The main target of the investigation is to reduce the cutting force measured with a force measurement platform underneath the workpiece. Concerning to the direction of the ultrasonic assistance, the authors expect lower cutting forces and longer endurance of the tool in the drilling process. To verify the frequencies and the amplitudes an FFT-analysis is performed. It shows the increasing damping depending on the infeed rate of the tool. The reducing of amplitude of the cutting force comes along. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drilling" title="drilling">drilling</a>, <a href="https://publications.waset.org/abstracts/search?q=machining" title=" machining"> machining</a>, <a href="https://publications.waset.org/abstracts/search?q=milling" title=" milling"> milling</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic" title=" ultrasonic"> ultrasonic</a> </p> <a href="https://publications.waset.org/abstracts/69538/analysis-of-the-cutting-force-with-ultrasonic-assisted-manufacturing-of-steel-s235jr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69538.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Atomic Layer Deposition of Metal Oxides on Si/C Materials for the Improved Cycling Stability of High-Capacity Lithium-Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Stehle">Philipp Stehle</a>, <a href="https://publications.waset.org/abstracts/search?q=Dragoljub%20Vrankovic"> Dragoljub Vrankovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Montaha%20Anjass"> Montaha Anjass</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to its high availability and extremely high specific capacity, silicon (Si) is the most promising anode material for next generation lithium-ion batteries (LIBs). However, Si anodes are suffering from high volume changes during cycling causing unstable solid-electrolyte interface (SEI). One approach for mitigation of these effects is to embed Si particles into a carbon matrix to create silicon/carbon composites (Si/C). These typically show more stable electrochemical performance than bare silicon materials. Nevertheless, the same failure mechanisms mentioned earlier appear in a less pronounced form. In this work, we further improved the cycling performance of two commercially available Si/C materials by coating thin metal oxide films of different thicknesses on the powders via Atomic Layer Deposition (ALD). The coated powders were analyzed via ICP-OES and AFM measurements. Si/C-graphite anodes with automotive-relevant loadings (~3.5 mAh/cm2) were processed out of the materials and tested in half coin cells (HCCs) and full pouch cells (FPCs). During long-term cycling in FPCs, a significant improvement was observed for some of the ALD-coated materials. After 500 cycles, the capacity retention was already up to 10% higher compared to the pristine materials. Cycling of the FPCs continued until they reached a state of health (SOH) of 80%. By this point, up to the triple number of cycles were achieved by ALD-coated compared to pristine anodes. Post-mortem analysis via various methods was carried out to evaluate the differences in SEI formation and thicknesses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silicon%20anodes" title="silicon anodes">silicon anodes</a>, <a href="https://publications.waset.org/abstracts/search?q=li-ion%20batteries" title=" li-ion batteries"> li-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20layer%20deposition" title=" atomic layer deposition"> atomic layer deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon-carbon%20composites" title=" silicon-carbon composites"> silicon-carbon composites</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20coatings" title=" surface coatings"> surface coatings</a> </p> <a href="https://publications.waset.org/abstracts/156422/atomic-layer-deposition-of-metal-oxides-on-sic-materials-for-the-improved-cycling-stability-of-high-capacity-lithium-ion-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156422.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> DNA Double-Strand Break–Capturing Nuclear Envelope Tubules Drive DNA Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mitra%20Shokrollahi">Mitra Shokrollahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mia%20Stanic"> Mia Stanic</a>, <a href="https://publications.waset.org/abstracts/search?q=Anisha%20Hundal"> Anisha Hundal</a>, <a href="https://publications.waset.org/abstracts/search?q=Janet%20N.%20Y.%20Chan"> Janet N.

It is unclear to what extent human DSBs display such repositioning. Here we show that the human nuclear envelope localizes to DSBs in a manner depending on DNA damage response (DDR) kinases and cytoplasmic microtubules acetylated by α-tubulin acetyltransferase-1 (ATAT1). These factors collaborate with the linker of nucleoskeleton and cytoskeleton complex (LINC), nuclear pore complex (NPC) protein NUP153, the nuclear lamina and kinesins KIF5B and KIF13B to generate DSB-capturing nuclear envelope tubules (dsbNETs). dsbNETs are partly supported by nuclear actin filaments and the circadian factor PER1 and reversed by kinesin KIFC3. Although dsbNETs promote repair and survival, they are also co-opted during poly (ADP-ribose) polymerase (PARP) inhibition to restrain BRCA1-deficient breast cancer cells and are hyper-induced in cells expressing the aging-linked lamin A mutant progerin. In summary, our results advance understanding of nuclear structure-function relationships, uncover a nuclear-cytoplasmic DDR and identify dsbNETs as critical factors in genome organization and stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage%20response" title="DNA damage response">DNA damage response</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20stability" title=" genome stability"> genome stability</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20envelope" title=" nuclear envelope"> nuclear envelope</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=age-related%20disorders" title=" age-related disorders"> age-related disorders</a> </p> <a href="https://publications.waset.org/abstracts/193774/dna-double-strand-break-capturing-nuclear-envelope-tubules-drive-dna-repair" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193774.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">16</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Driving Green Public Procurement – A Framework for a Supporting Structure for Public Authorities Based on Good Practices in Europe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pia%20Moschall">Pia Moschall</a>, <a href="https://publications.waset.org/abstracts/search?q=Kathrin%20Sackmann"> Kathrin Sackmann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering a purchasing volume of around two trillion Euros per year, which equals about 14% of the European Union’s gross domestic product, European public authorities have significant market power. Making use of this market power by prioritizing the procurement of green products and services offers a great potential to contribute to the Green New Deal. The market demand that is created by Green Public Procurement (GPP) sets incentives for European producers to design and develop Green Products and Eco-Innovations. However, most procurement still does not consider environmental criteria. The goal of the work is to encourage the adaptation of GPP in the European Union. To this end, the drivers for the adaptation were investigated over different case studies. The paper analyzes good-practice cases from European authorities from 2010 to 2020 that were provided by the European Commission. This analysis was guided by Philipp Mayring’s method of qualitative content analysis, whereby the inductively formed categories led to the identification of nine major drivers. The most important ones are ‘use of official guidelines and standards, ‘political support and requirements as well as ‘market research and involvement.’ Further, the paper discusses mutual dependencies between several drivers and how to exploit them. A supporting infrastructure was identified as a crucial factor for the successful adaption of green public procurement. In the next step, the work aims to examine on which administrative level the single drivers can be implemented most effectively. Practical implications of this research are recommendations on how to create a supporting structure on a municipal, federal and national level, including training for the responsible staff, support tools, as well as guidelines and standards for involved stakeholders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=content%20analysis" title="content analysis">content analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20public%20procurement" title=" green public procurement"> green public procurement</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20authorities" title=" public authorities"> public authorities</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20procurement" title=" sustainable procurement"> sustainable procurement</a> </p> <a href="https://publications.waset.org/abstracts/138033/driving-green-public-procurement-a-framework-for-a-supporting-structure-for-public-authorities-based-on-good-practices-in-europe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138033.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Characterization of Lahar Sands for Reclamation Projects in the Manila Bay, Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julian%20Sandoval">Julian Sandoval</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Schober"> Philipp Schober</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lahar sand (lahars) is a material that originates from volcanic debris flows. During and after a volcano eruption, the lahars can move at speeds up to 22 meters per hour or more, so they can easily cover extensive areas and destroy any structure in their path. Mount Pinatubo eruption (1991) brought lahars to its vicinities, and its use has been a matter of research ever since. Lahars are often disposed of for land reclamation projects in the Manila Bay, Philippines. After reclamation, some deep loss deposits may still present and they are prone to liquefaction. To mitigate the risk of liquefaction of such deposits, Vibro compaction has been proposed and used as a ground improvement technique. Cone penetration testing (CPT) campaigns are usually initiated to monitor the effectiveness of the ground improvement works by vibro compaction. The CPT cone resistance is used to analyses the in-situ relative density of the reclaimed sand before and after compaction. Available correlations between the CPT cone resistance and the relative density are only valid for non-crushable sands. Due to the partially crushable nature of lahars, the CPT data requires to be adjusted to allow for a correct interpretation of the CPT data. The objective of this paper is to characterize the chemical and mechanical properties of the lahar sands used for an ongoing project in the Port of Manila, which comprises reclamation activities using lahars from the east of Mount Pinatubo, it investigates their effect in the proposed correction factor. Additionally, numerous CPTs were carried out in a test trial and during the execution of the project. Based on this data, the influence of the grid spacing, compaction steps and the holding time on the compaction results are analyzed. Moreover, the so-called “aging effect” of the lahars is studied by comparing the results of the CPT testing campaign at different times after the vibro compaction activities. A considerable increase in the tip resistance of the CPT was observed over time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vibro%20compaction" title="vibro compaction">vibro compaction</a>, <a href="https://publications.waset.org/abstracts/search?q=CPT" title=" CPT"> CPT</a>, <a href="https://publications.waset.org/abstracts/search?q=lahar%20sands" title=" lahar sands"> lahar sands</a>, <a href="https://publications.waset.org/abstracts/search?q=correction%20factor" title=" correction factor"> correction factor</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title=" chemical composition"> chemical composition</a> </p> <a href="https://publications.waset.org/abstracts/111831/characterization-of-lahar-sands-for-reclamation-projects-in-the-manila-bay-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111831.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> One Health Approach: The Importance of Improving the Identification of Waterborne Bacteria in Austrian Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aurora%20Gitto">Aurora Gitto</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Proksch"> Philipp Proksch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presence of various microorganisms (bacteria, fungi) in surface water and groundwater represents an important issue for human health worldwide. The matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS) has emerged as a promising and reliable tool for bacteria identification in clinical diagnostic microbiology and environmental strains thanks to an ionization technique that uses a laser energy absorbing matrix to create ions from large molecules with minimal fragmentation. The study aims first to conceptualise and set up library information and create a comprehensive database of MALDI-TOF-MS spectra from environmental water samples. The samples were analysed over a year (2021-2022) using membrane filtration methodology (0.45 μm and 0.22 μm) and then isolated on R2A agar for a period of 5 days and Yeast extract agar growing at 22 °C up to 4 days and 37 °C for 48 hours. The undetected organisms by MALDI-TOF-MS were analysed by PCR and then sequenced. The information obtained by the sequencing was further implemented in the MALDI-TOF-MS library. Among the culturable bacteria, the results show how the incubator temperature affects the growth of some genera instead of others, as demonstrated by Pseudomonas sp., which grows at 22 °C, compared to Bacillus sp., which is abundant at 37 °C. The bacteria community shows a variation in composition also between the media used, as demonstrated with R2A agar which has been defined by a higher presence of organisms not detected compared to YEA. Interesting is the variability of the Genus over one year of sampling and how the seasonality impacts the bacteria community; in fact, in some sampling locations, we observed how the composition changed, moving from winter to spring and summer. In conclusion, the bacteria community in groundwater and river bank filtration represents important information that needs to be added to the library to simplify future water quality analysis but mainly to prevent potential risks to human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title="water quality">water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=MALDI-TOF-MS" title=" MALDI-TOF-MS"> MALDI-TOF-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=sequencing" title=" sequencing"> sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=library" title=" library"> library</a> </p> <a href="https://publications.waset.org/abstracts/166306/one-health-approach-the-importance-of-improving-the-identification-of-waterborne-bacteria-in-austrian-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166306.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> BFDD-S: Big Data Framework to Detect and Mitigate DDoS Attack in SDN Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amirreza%20Fazely%20Hamedani">Amirreza Fazely Hamedani</a>, <a href="https://publications.waset.org/abstracts/search?q=Muzzamil%20Aziz"> Muzzamil Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Wieder"> Philipp Wieder</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Yahyapour"> Ramin Yahyapour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software-defined networking in recent years came into the sight of so many network designers as a successor to the traditional networking. Unlike traditional networks where control and data planes engage together within a single device in the network infrastructure such as switches and routers, the two planes are kept separated in software-defined networks (SDNs). All critical decisions about packet routing are made on the network controller, and the data level devices forward the packets based on these decisions. This type of network is vulnerable to DDoS attacks, degrading the overall functioning and performance of the network by continuously injecting the fake flows into it. This increases substantial burden on the controller side, and the result ultimately leads to the inaccessibility of the controller and the lack of network service to the legitimate users. Thus, the protection of this novel network architecture against denial of service attacks is essential. In the world of cybersecurity, attacks and new threats emerge every day. It is essential to have tools capable of managing and analyzing all this new information to detect possible attacks in real-time. These tools should provide a comprehensive solution to automatically detect, predict and prevent abnormalities in the network. Big data encompasses a wide range of studies, but it mainly refers to the massive amounts of structured and unstructured data that organizations deal with on a regular basis. On the other hand, it regards not only the volume of the data; but also that how data-driven information can be used to enhance decision-making processes, security, and the overall efficiency of a business. This paper presents an intelligent big data framework as a solution to handle illegitimate traffic burden on the SDN network created by the numerous DDoS attacks. The framework entails an efficient defence and monitoring mechanism against DDoS attacks by employing the state of the art machine learning techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apache%20spark" title="apache spark">apache spark</a>, <a href="https://publications.waset.org/abstracts/search?q=apache%20kafka" title=" apache kafka"> apache kafka</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a>, <a href="https://publications.waset.org/abstracts/search?q=DDoS%20attack" title=" DDoS attack"> DDoS attack</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=SDN%20network" title=" SDN network"> SDN network</a> </p> <a href="https://publications.waset.org/abstracts/141560/bfdd-s-big-data-framework-to-detect-and-mitigate-ddos-attack-in-sdn-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141560.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Open Innovation in SMEs: A Multiple Case Study of Collaboration between Start-ups and Craft Enterprises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carl-Philipp%20Valentin%20Beichert">Carl-Philipp Valentin Beichert</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Seger"> Marcel Seger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital transformation and climate change require small and medium-sized enterprises (SME) to rethink their way of doing business. Inter-firm collaboration is recognized as helpful means of promoting innovation and competitiveness. In this context, collaborations with start-ups offer valuable opportunities through their innovative products, services, and business models. SMEs, and in particular German craft enterprises, play an important role in the country’s society and economy. Companies in this heterogeneous economic sector have unique characteristics and are limited in their ability to innovate due to their small size and lack of resources. Collaborating with start-ups could help to overcome these shortcomings. To investigate how collaborations emerge and what factors are decisive to successfully drive collaboration, we apply an explorative, qualitative research design. A sample of ten case studies was selected, with the collaboration between a start-up and a craft enterprise forming the unit of analysis. Semi-structured interviews with 20 company representatives allow for a two-sided perspective on the respective collaboration. The interview data is enriched by publicly available data and three expert interviews. As a result, objectives, initiation practices, applied collaboration types, barriers, as well as key success factors could be identified. The results indicate a three-phase collaboration process comprising an initiation, concept, and partner phase (ICP). The ICP framework proposed accordingly highlights the success factors (personal fit, communication, expertise, structure, network) for craft enterprises and start-ups for each collaboration phase. The role of a mediator in the start-up company, with strong expertise in the respective craft sector, is considered an important lever for overcoming barriers such as cultural and communication differences. The ICP framework thus provides promising directions for further research and can help practitioners establish successful collaborations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20innovation" title="open innovation">open innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=SME" title=" SME"> SME</a>, <a href="https://publications.waset.org/abstracts/search?q=craft%20businesses" title=" craft businesses"> craft businesses</a>, <a href="https://publications.waset.org/abstracts/search?q=startup%20collaboration" title=" startup collaboration"> startup collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20research" title=" qualitative research"> qualitative research</a> </p> <a href="https://publications.waset.org/abstracts/164974/open-innovation-in-smes-a-multiple-case-study-of-collaboration-between-start-ups-and-craft-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164974.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> A Concept for Flexible Battery Cell Manufacturing from Low to Medium Volumes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tim%20Giesen">Tim Giesen</a>, <a href="https://publications.waset.org/abstracts/search?q=Raphael%20Adamietz"> Raphael Adamietz</a>, <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Mayer"> Pablo Mayer</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Stiefel"> Philipp Stiefel</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Alle"> Patrick Alle</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirk%20Schlenker"> Dirk Schlenker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The competitiveness and success of new electrical energy storages such as battery cells are significantly dependent on a short time-to-market. Producers who decide to supply new battery cells to the market need to be easily adaptable in manufacturing with respect to the early customers’ needs in terms of cell size, materials, delivery time and quantity. In the initial state, the required output rates do not yet allow the producers to have a fully automated manufacturing line nor to supply handmade battery cells. Yet there was no solution for manufacturing battery cells in low to medium volumes in a reproducible way. Thus, in terms of cell format and output quantity, a concept for the flexible assembly of battery cells was developed by the Fraunhofer-Institute for Manufacturing Engineering and Automation. Based on clustered processes, the modular system platform can be modified, enlarged or retrofitted in a short time frame according to the ordered product. The paper shows the analysis of the production steps from a conventional battery cell assembly line. Process solutions were found by using I/O-analysis, functional structures, and morphological boxes. The identified elementary functions were subsequently clustered by functional coherences for automation solutions and thus the single process cluster was generated. The result presented in this paper enables to manufacture different cell products on the same production system using seven process clusters. The paper shows the solution for a batch-wise flexible battery cell production using advanced process control. Further, the performed tests and benefits by using the process clusters as cyber-physical systems for an integrated production and value chain are discussed. The solution lowers the hurdles for SMEs to launch innovative cell products on the global market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automation" title="automation">automation</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20production" title=" battery production"> battery production</a>, <a href="https://publications.waset.org/abstracts/search?q=carrier" title=" carrier"> carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20process%20control" title=" advanced process control"> advanced process control</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber-physical%20system" title=" cyber-physical system"> cyber-physical system</a> </p> <a href="https://publications.waset.org/abstracts/79972/a-concept-for-flexible-battery-cell-manufacturing-from-low-to-medium-volumes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79972.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The KAPSARC Energy Policy Database: Introducing a Quantified Library of China's Energy Policies </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Galkin">Philipp Galkin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Government policy is a critical factor in the understanding of energy markets. Regardless, it is rarely approached systematically from a research perspective. Gaining a precise understanding of what policies exist, their intended outcomes, geographical extent, duration, evolution, etc. would enable the research community to answer a variety of questions that, for now, are either oversimplified or ignored. Policy, on its surface, also seems a rather unstructured and qualitative undertaking. There may be quantitative components, but incorporating the concept of policy analysis into quantitative analysis remains a challenge. The KAPSARC Energy Policy Database (KEPD) is intended to address these two energy policy research limitations. Our approach is to represent policies within a quantitative library of the specific policy measures contained within a set of legal documents. Each of these measures is recorded into the database as a single entry characterized by a set of qualitative and quantitative attributes. Initially, we have focused on the major laws at the national level that regulate coal in China. However, KAPSARC is engaged in various efforts to apply this methodology to other energy policy domains. To ensure scalability and sustainability of our project, we are exploring semantic processing using automated computer algorithms. Automated coding can provide a more convenient input data for human coders and serve as a quality control option. Our initial findings suggest that the methodology utilized in KEPD could be applied to any set of energy policies. It also provides a convenient tool to facilitate understanding in the energy policy realm enabling the researcher to quickly identify, summarize, and digest policy documents and specific policy measures. The KEPD captures a wide range of information about each individual policy contained within a single policy document. This enables a variety of analyses, such as structural comparison of policy documents, tracing policy evolution, stakeholder analysis, and exploring interdependencies of policies and their attributes with exogenous datasets using statistical tools. The usability and broad range of research implications suggest a need for the continued expansion of the KEPD to encompass a larger scope of policy documents across geographies and energy sectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China" title="China">China</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20policy" title=" energy policy"> energy policy</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20analysis" title=" policy analysis"> policy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20database" title=" policy database"> policy database</a> </p> <a href="https://publications.waset.org/abstracts/23550/the-kapsarc-energy-policy-database-introducing-a-quantified-library-of-chinas-energy-policies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23550.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Comparison of Cognitive Load in Virtual Reality and Conventional Simulation-Based Training: A Randomized Controlled Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Wagner">Michael Wagner</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Steinbauer"> Philipp Steinbauer</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Katharina%20Lietz"> Andrea Katharina Lietz</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Hoffelner"> Alexander Hoffelner</a>, <a href="https://publications.waset.org/abstracts/search?q=Johannes%20Fessler"> Johannes Fessler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cardiopulmonary resuscitations are stressful situations in which vital decisions must be made within seconds. Lack of routine due to the infrequency of pediatric emergencies can lead to serious medical and communication errors. Virtual reality can fundamentally change the way simulation training is conducted in the future. It appears to be a useful learning tool for technical and non-technical skills. It is important to investigate the use of VR in providing a strong sense of presence within simulations. Methods: In this randomized study, we will enroll doctors and medical students from the Medical University of Vienna, who will receive learning material regarding the resuscitation of a one-year-old child. The study will be conducted in three phases. In the first phase, 20 physicians and 20 medical students from the Medical University of Vienna will be included. They will perform simulation-based training with a standardized scenario of a critically ill child with a hypovolemic shock. The main goal of this phase is to establish a baseline for the following two phases to generate comparative values regarding cognitive load and stress. In phase 2 and 3, the same participants will perform the same scenario in a VR setting. In both settings, on three set points of progression, one of three predefined events is triggered. For each event, three different stress levels (easy, medium, difficult) will be defined. Stress and cognitive load will be analyzed using the NASA Task Load Index, eye-tracking parameters, and heart rate. Subsequently, these values will be compared between VR training and traditional simulation-based training. Hypothesis: We hypothesize that the VR training and the traditional training groups will not differ in physiological response (cognitive load, heart rate, and heart rate variability). We further assume that virtual reality training can be used as cost-efficient additional training. Objectives: The aim of this study is to measure cognitive load and stress level during a real-life simulation training and compare it with VR training in order to show that VR training evokes the same physiological response and cognitive load as real-life simulation training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title="virtual reality">virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20load" title=" cognitive load"> cognitive load</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20virtual%20reality%20training" title=" adaptive virtual reality training"> adaptive virtual reality training</a> </p> <a href="https://publications.waset.org/abstracts/152955/comparison-of-cognitive-load-in-virtual-reality-and-conventional-simulation-based-training-a-randomized-controlled-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152955.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> A Metric to Evaluate Conventional and Electrified Vehicles in Terms of Customer-Oriented Driving Dynamics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephan%20Schiffer">Stephan Schiffer</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Kain"> Andreas Kain</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Wilde"> Philipp Wilde</a>, <a href="https://publications.waset.org/abstracts/search?q=Maximilian%20Helbing"> Maximilian Helbing</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernard%20B%C3%A4ker"> Bernard Bäker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Automobile manufacturers progressively focus on a downsizing strategy to meet the EU's CO2 requirements concerning type-approval consumption cycles. The reduction in naturally aspirated engine power is compensated by increased levels of turbocharging. By downsizing conventional engines, CO2 emissions are reduced. However, it also implicates major challenges regarding longitudinal dynamic characteristics. An example of this circumstance is the delayed turbocharger-induced torque reaction which leads to a partially poor response behavior of the vehicle during acceleration operations. That is why it is important to focus conventional drive train design on real customer driving again. The currently considered dynamic maneuvers like the acceleration time 0-100 km/h discussed by journals and car manufacturers describe longitudinal dynamics experienced by a driver inadequately. For that reason we present the realization and evaluation of a comprehensive proband study. Subjects are provided with different vehicle concepts (electrified vehicles, vehicles with naturally aspired engines and vehicles with different concepts of turbochargers etc.) in order to find out which dynamic criteria are decisive for a subjectively strong acceleration and response behavior of a vehicle. Subsequently, realistic acceleration criteria are derived. By weighing the criteria an evaluation metric is developed to objectify customer-oriented transient dynamics. Fully-electrified vehicles are the benchmark in terms of customer-oriented longitudinal dynamics. The electric machine provides the desired torque almost without delay. This advantage compared to combustion engines is especially noticeable at low engine speeds. In conclusion, we will show the degree to which extent customer-relevant longitudinal dynamics of conventional vehicles can be approximated to electrified vehicle concepts. Therefore, various technical measures (turbocharger concepts, 48V electrical chargers etc.) and drive train designs (e.g. varying the final drive) are presented and evaluated in order to strengthen the vehicle’s customer-relevant transient dynamics. As a rating size the newly developed evaluation metric will be used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=48V" title="48V">48V</a>, <a href="https://publications.waset.org/abstracts/search?q=customer-oriented%20driving%20dynamics" title=" customer-oriented driving dynamics"> customer-oriented driving dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20charger" title=" electric charger"> electric charger</a>, <a href="https://publications.waset.org/abstracts/search?q=electrified%20vehicles" title=" electrified vehicles"> electrified vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20concepts" title=" vehicle concepts"> vehicle concepts</a> </p> <a href="https://publications.waset.org/abstracts/66580/a-metric-to-evaluate-conventional-and-electrified-vehicles-in-terms-of-customer-oriented-driving-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">406</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Dosimetric Comparison among Different Head and Neck Radiotherapy Techniques Using PRESAGE™ Dosimeter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jalil%20ur%20Rehman">Jalil ur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20C.%20Tailor"> Ramesh C.

Materials and Methods: Computer tomography (CT) scans of radiological physics center (RPC) head and neck anthropomorphic phantom with both RPC standard insert and PRESAGETM insert were acquired separated with Philipp’s CT scanner and both CT scans were exported via DICOM to the Pinnacle version 9.4 treatment planning system (TPS). Each plan was delivered twice to the RPC phantom first containing the RPC standard insert having TLD and film dosimeters and then again containing the Presage insert having 3-D dosimeter (PRESAGETM) by using a Varian True Beam linear accelerator. After irradiation, the standard insert including point dose measurements (TLD) and planar Gafchromic® EBT film measurement were read using RPC standard procedure. The 3D dose distribution from PRESAGETM was read out with the Duke Midsized optical scanner dedicated to RPC (DMOS-RPC). Dose volume histogram (DVH), mean and maximal doses for organs at risk were calculated and compared among each head and neck technique. The prescription dose was same for all head and neck radiotherapy techniques which was 6.60 Gy/friction. Beam profile comparison and gamma analysis were used to quantify agreements among film measurement, PRESAGETM measurement and calculated dose distribution. Quality assurances of all plans were performed by using ArcCHECK method. Results: VMAT delivered the lowest mean and maximum doses to organ at risk (spinal cord, parotid) than IMRT and 3DCRT. Such dose distribution was verified by absolute dose distribution using thermoluminescent dosimeter (TLD) system. The central axial, sagittal and coronal planes were evaluated using 2D gamma map criteria(± 5%/3 mm) and results were 99.82% (axial), 99.78% (sagital), 98.38% (coronal) for VMAT plan and found the agreement between PRESAGE and pinnacle was better than IMRT and 3D-CRT plan excludes a 7 mm rim at the edge of the dosimeter. Profile showed good agreement for all plans between film, PRESAGE and pinnacle and 3D gamma was performed for PTV and OARs, VMAT and 3DCRT endow with better agreement than IMRT. Conclusion: VMAT delivered lowered mean and maximal doses to organs at risk and better PTV coverage during head and neck radiotherapy. TLD, EBT film and PRESAGETM dosimeters suggest that VMAT was better for the treatment of head and neck cancer than IMRT and 3D-CRT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RPC" title="RPC">RPC</a>, <a href="https://publications.waset.org/abstracts/search?q=3DCRT" title=" 3DCRT"> 3DCRT</a>, <a href="https://publications.waset.org/abstracts/search?q=IMRT" title=" IMRT"> IMRT</a>, <a href="https://publications.waset.org/abstracts/search?q=VMAT" title=" VMAT"> VMAT</a>, <a href="https://publications.waset.org/abstracts/search?q=EBT2%20film" title=" EBT2 film"> EBT2 film</a>, <a href="https://publications.waset.org/abstracts/search?q=TLD" title=" TLD"> TLD</a>, <a href="https://publications.waset.org/abstracts/search?q=PRESAGETM" title=" PRESAGETM"> PRESAGETM</a> </p> <a href="https://publications.waset.org/abstracts/6841/dosimetric-comparison-among-different-head-and-neck-radiotherapy-techniques-using-presage-dosimeter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6841.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">395</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Structural Invertibility and Optimal Sensor Node Placement for Error and Input Reconstruction in Dynamic Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maik%20Kschischo">Maik Kschischo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominik%20Kahl"> Dominik Kahl</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Wendland"> Philipp Wendland</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Weber"> Andreas Weber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Understanding and modelling of real-world complex dynamic systems in biology, engineering and other fields is often made difficult by incomplete knowledge about the interactions between systems states and by unknown disturbances to the system. In fact, most real-world dynamic networks are open systems receiving unknown inputs from their environment. To understand a system and to estimate the state dynamics, these inputs need to be reconstructed from output measurements. Reconstructing the input of a dynamic system from its measured outputs is an ill-posed problem if only a limited number of states is directly measurable. A first requirement for solving this problem is the invertibility of the input-output map. In our work, we exploit the fact that invertibility of a dynamic system is a structural property, which depends only on the network topology. Therefore, it is possible to check for invertibility using a structural invertibility algorithm which counts the number of node disjoint paths linking inputs and outputs. The algorithm is efficient enough, even for large networks up to a million nodes. To understand structural features influencing the invertibility of a complex dynamic network, we analyze synthetic and real networks using the structural invertibility algorithm. We find that invertibility largely depends on the degree distribution and that dense random networks are easier to invert than sparse inhomogeneous networks. We show that real networks are often very difficult to invert unless the sensor nodes are carefully chosen. To overcome this problem, we present a sensor node placement algorithm to achieve invertibility with a minimum set of measured states. This greedy algorithm is very fast and also guaranteed to find an optimal sensor node-set if it exists. Our results provide a practical approach to experimental design for open, dynamic systems. Since invertibility is a necessary condition for unknown input observers and data assimilation filters to work, it can be used as a preprocessing step to check, whether these input reconstruction algorithms can be successful. If not, we can suggest additional measurements providing sufficient information for input reconstruction. Invertibility is also important for systems design and model building. Dynamic models are always incomplete, and synthetic systems act in an environment, where they receive inputs or even attack signals from their exterior. Being able to monitor these inputs is an important design requirement, which can be achieved by our algorithms for invertibility analysis and sensor node placement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data-driven%20dynamic%20systems" title="data-driven dynamic systems">data-driven dynamic systems</a>, <a href="https://publications.waset.org/abstracts/search?q=inversion%20of%20dynamic%20systems" title=" inversion of dynamic systems"> inversion of dynamic systems</a>, <a href="https://publications.waset.org/abstracts/search?q=observability" title=" observability"> observability</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20design" title=" experimental design"> experimental design</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20node%20placement" title=" sensor node placement"> sensor node placement</a> </p> <a href="https://publications.waset.org/abstracts/112061/structural-invertibility-and-optimal-sensor-node-placement-for-error-and-input-reconstruction-in-dynamic-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112061.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Dynamic Changes in NT-proBNP Levels in Unrelated Donors during Hematopoietic Stem Cells Mobilization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalia%20V.%20Minaeva">Natalia V.

Over the last few decades, the Center for International Blood and Marrow Transplant Research (CIBMTR) and the World Marrow Donor Association (WMDA) have been actively working to ensure the safety of the hematopoietic stem cell (HSC) donation process. Registration of adverse events that may occur during the donation period and establishing a relationship between donation and side effects are included in the WMDA international standards. The level of blood serum N-terminal pro-brain natriuretic peptide (NT-proBNP) is an early marker of myocardial stress. Due to the high analytical sensitivity and specificity, laboratory assessment of NT-proBNP makes it possible to objectively diagnose myocardial dysfunction. It is well known that the main stimulus for proBNP synthesis and secretion from atrial and ventricular cardiac myocytes is myocyte stretch and increasement of myocardial extensibility and pressure in the heart chambers. Аim. The aim of the study was to assess the dynamic changes in the levels of blood serum N-terminal pro-brain natriuretic peptide of unrelated donors at various stages of hematopoietic stem cell mobilization. Materials. We have examined 133 unrelated donors, including 92 men and 41 women, that have been included into the study. The NT-proBNP levels were measured before the start of mobilization, then on the day of apheresis, and after the donation of allogeneic HSC. The relationship between NT-proBNP levels and body mass index (BMI), ferritin, hemoglobin, and white blood cells (WBC) levels was assessed on the day of apheresis. The median age of donors was 34 years. Mobilization of HSCs was managed with filgrastim administration at a dose of 10 μg/kg daily for 4-5 days. The first leukocytapheresis was performed on day 4 from the start of filgrastim administration. Quantitative values of the blood serum NT-proBNP level are presented as a median (Me), first and third quartiles (Q1-Q3). Comparative analysis was carried out using the t-test and correlation analysis as well by Spearman method. Results. The baseline blood serum NT-proBNP levels in all 133 donors were within the reference values (<125 pg/ml) and equaled 21,6 (10,0; 43,3) pg/ml. At the same time, the level of NT-proBNP in women was significantly higher than that of men. On the day of the HSC apheresis, a significant increase of blood serum NT-proBNP levels was detected and equald 131,2 (72,6; 165,3) pg/ml (p<0,001), with higher rates in female donors. A statistically significant weak inverse correleation was established between the level of NT-proBNP and the BMI of donors (-0.18, p = 0,03), as well as the level of hemoglobin (-0.33, p <0,001), and ferritin levels (-0.19, p = 0,03). No relationship has been established between the magnitude of WBC levels achieved as a result of the mobilization of HSC on the day of leukocytapheresis. A day after the apheresis, the blood serum NT-proBNP levels still exceeded the reference values, but there was a decreasing tendency. Conclusion. An increase of the blood serum NT-proBNP level in unrelated donors during the mobilization of HSC was established. Future studies should clarify the reason for this phenomenon, as well as its effects on donors' long-term health. <p class="card-text"><strong>Keywords:</strong> <a
