class="card-text"><strong>Abstract:</strong></p> Given a patent document, identifying distinct semantic annotations is an interesting research aspect. Text annotation helps the patent practitioners such as examiners and patent attorneys to quickly identify the key arguments of any invention, successively providing a timely marking of a patent text. In the process of manual patent analysis, to attain better readability, recognising the semantic information by marking paragraphs is in practice. This semantic annotation process is laborious and time-consuming. To alleviate such a problem, we proposed a dataset to train machine learning algorithms to automate the highlighting process. The contributions of this work are: i) we developed a multi-class dataset of size 150k samples by traversing USPTO patents over a decade, ii) articulated statistics and distributions of data using imperative exploratory data analysis, iii) baseline Machine Learning models are developed to utilize the dataset to address patent paragraph highlighting task, and iv) future path to extend this work using Deep Learning and domain-specific pre-trained language models to develop a tool to highlight is provided. This work assists patent practitioners in highlighting semantic information automatically and aids in creating a sustainable and efficient patent analysis using the aptitude of machine learning. <p class="card-text"><strong>Keywords:</strong> <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=patents" title=" patents"> patents</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20sentiment%20analysis" title=" patent sentiment analysis"> patent sentiment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20information%20retrieval" title=" patent information retrieval"> patent information retrieval</a> </p> <a href="https://publications.waset.org/abstracts/144394/pasa-a-dataset-for-patent-sentiment-analysis-to-highlight-patent-paragraphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144394.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">90</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">59</span> Spatiotemporal Propagation and Pattern of Epileptic Spike Predict Seizure Onset Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Mohammadpour">Mostafa Mohammadpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Kapeller"> Christoph Kapeller</a>, <a href="https://publications.waset.org/abstracts/search?q=Christy%20Li"> Christy Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Josef%20Scharinger"> Josef Scharinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Guger"> Christoph Guger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interictal spikes provide valuable information on electrocorticography (ECoG), which aids in surgical planning for patients who suffer from refractory epilepsy. However, the shape and temporal dynamics of these spikes remain unclear. The purpose of this work was to analyze the shape of interictal spikes and measure their distance to the seizure onset zone (SOZ) to use in epilepsy surgery. Thirteen patients' data from the iEEG portal were retrospectively studied. For analysis, half an hour of ECoG data was used from each patient, with the data being truncated before the onset of a seizure. Spikes were first detected and grouped in a sequence, then clustered into interictal epileptiform discharges (IEDs) and non-IED groups using two-step clustering. The distance of the spikes from IED and non-IED groups to SOZ was quantified and compared using the Wilcoxon rank-sum test. Spikes in the IED group tended to be in SOZ or close to it, while spikes in the non-IED group were in distance of SOZ or non-SOZ area. At the group level, the distribution for sharp wave, positive baseline shift, slow wave, and slow wave to sharp wave ratio was significantly different for IED and non-IED groups. The distance of the IED cluster was 10.00mm and significantly closer to the SOZ than the 17.65mm for non-IEDs. These findings provide insights into the shape and spatiotemporal dynamics of spikes that could influence the network mechanisms underlying refractory epilepsy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spike%20propagation" title="spike propagation">spike propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=spike%20pattern" title=" spike pattern"> spike pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=clustering" title=" clustering"> clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=SOZ" title=" SOZ"> SOZ</a> </p> <a href="https://publications.waset.org/abstracts/176533/spatiotemporal-propagation-and-pattern-of-epileptic-spike-predict-seizure-onset-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176533.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">63</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">58</span> Track and Evaluate Cortical Responses Evoked by Electrical Stimulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyosuke%20Kamada">Kyosuke Kamada</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Kapeller"> Christoph Kapeller</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Jordan"> Michael Jordan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Mohammadpour"> Mostafa Mohammadpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Christy%20Li"> Christy Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Guger"> Christoph Guger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cortico-cortical evoked potentials (CCEP) refer to responses generated by cortical electrical stimulation at distant brain sites. These responses provide insights into the functional networks associated with language or motor functions, and in the context of epilepsy, they can reveal pathological networks. Locating the origin and spread of seizures within the cortex is crucial for pre-surgical planning. This process can be enhanced by employing cortical stimulation at the seizure onset zone (SOZ), leading to the generation of CCEPs in remote brain regions that may be targeted for disconnection. In the case of a 24-year-old male patient suffering from intractable epilepsy, corpus callosotomy was performed as part of the treatment. DTI-MRI imaging, conducted using a 3T MRI scanner for fiber tracking, along with CCEP, is used as part of an assessment for surgical planning. Stimulation of the SOZ, with alternating monophasic pulses of 300µs duration and 15mA current intensity, resulted in CCEPs on the contralateral frontal cortex, reaching a peak amplitude of 206µV with a latency of 31ms, specifically in the left pars triangularis. The related fiber tracts were identified with a two-tensor unscented Kalman filter (UKF) technique, showing transversal fibers through the corpus callosum. The CCEPs were monitored through the progress of the surgery. Notably, the SOZ-associated CCEPs exhibited a reduction following the resection of the anterior portion of the corpus callosum, reaching the identified connecting fibers. This intervention demonstrated a potential strategy for mitigating the impact of intractable epilepsy through targeted disconnection of identified cortical regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CCEP" title="CCEP">CCEP</a>, <a href="https://publications.waset.org/abstracts/search?q=SOZ" title=" SOZ"> SOZ</a>, <a href="https://publications.waset.org/abstracts/search?q=Corpus%20callosotomy" title=" Corpus callosotomy"> Corpus callosotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=DTI" title=" DTI"> DTI</a> </p> <a href="https://publications.waset.org/abstracts/176639/track-and-evaluate-cortical-responses-evoked-by-electrical-stimulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176639.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">67</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">57</span> An Approach on the Design of a Solar Cell Characterization Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Mayer">Christoph Mayer</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominik%20Holzmann"> Dominik Holzmann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the development of a compact, portable and easy to handle solar cell characterization device.

To accomplish this, we use a literature-based discussion of our case study on practice. We want to describe neuroscientific-radiological findings in the context of mathematics education and point out stimulating connections between both perspectives.

The recorded data from a milling test cut is used to classify the cut as stable or unstable based on the frequency analysis. The test cut result is fed to a Bayesian stability learning algorithm at the University of Tennessee, Knoxville, Tennessee, USA. The algorithm calculates the probability of stability as a function of axial depth of cut and spindle speed and recommends the parameters for the next test cut.

In addition, new regulations, such as the German Supply Chain Act, fostered the inclusion of sustainable incl. governance selection criteria in the selection process. In order to provide a systematic approach to select the most suitable sustainable suppliers, this study quantifies the importance and prioritizes the relevant selection criteria across 17 German industries using the Fuzzy Analytical Hierarchy Process. Results show that economic criteria are still the most important in the selection decision averaging a global weight of 51%. However, environmental, social, and governance (ESG) criteria are combined, on average, almost equally important, with global weights of 22%, 16%, and 11%, respectively. While the type of industry influences criteria weights, other factors, such as type of purchasing or demographic factors, appear to have little impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ESG" title="ESG">ESG</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20analytical%20hierarchy%20process" title=" fuzzy analytical hierarchy process"> fuzzy analytical hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20supplier%20selection" title=" sustainable supplier selection"> sustainable supplier selection</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/166297/the-relevance-of-environmental-social-and-governance-in-sustainable-supplier-selection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166297.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">87</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">51</span> Model-Based Process Development for the Comparison of a Radial Riveting and Roller Burnishing Process in Mechanical Joining Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Beyer">Tobias Beyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Friedrich"> Christoph Friedrich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern simulation methodology using finite element models is nowadays a recognized tool for product design/optimization. Likewise, manufacturing process design is increasingly becoming the focus of simulation methodology in order to enable sustainable results based on reduced real-life tests here as well. In this article, two process simulations -radial riveting and roller burnishing- used for mechanical joining of components are explained. In the first step, the required boundary conditions are developed and implemented in the respective simulation models. This is followed by process space validation. With the help of the validated models, the interdependencies of the input parameters are investigated and evaluated by means of sensitivity analyses. Limit case investigations are carried out and evaluated with the aid of the process simulations. Likewise, a comparison of the two joining methods to each other becomes possible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FEM" title="FEM">FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=model-based%20process%20development" title=" model-based process development"> model-based process development</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20simulation" title=" process simulation"> process simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20riveting" title=" radial riveting"> radial riveting</a>, <a href="https://publications.waset.org/abstracts/search?q=roller%20burnishing" title=" roller burnishing"> roller burnishing</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a> </p> <a href="https://publications.waset.org/abstracts/151441/model-based-process-development-for-the-comparison-of-a-radial-riveting-and-roller-burnishing-process-in-mechanical-joining-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151441.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">108</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">50</span> Large Neural Networks Learning From Scratch With Very Few Data and Without Explicit Regularization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Linse">Christoph Linse</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Martinetz"> Thomas Martinetz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent findings have shown that Neural Networks generalize also in over-parametrized regimes with zero training error.

In the 1960s, it evolved from considering only economic criteria, such as price, quality, and performance, to including environmental and social criteria nowadays. Although receiving considerable attention from scholars and practitioners over the past decades, existing research has not considered governance criteria so far. This is, however, surprising, as ESG (environmental, social, and governance) criteria have gained considerable attention. In order to complement ESG criteria in the supplier selection process, this study investigates German DAX and MDAX companies and evaluates the impact of governance criteria along their supplier selection process. Moreover, it proposes a set of criteria for the respective process steps. Specifically, eleven criteria for the first process step and five criteria for the second process step are identified. This paper contributes to a better understanding of the supplier selection process by elucidating the relevance of governance criteria in the supplier selection process and providing a set of empirically developed governance criteria. These results can be applied by practitioners to complement the criteria set in the supplier selection process and thus balance economic, environmental, social, and governance targets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ESG" title="ESG">ESG</a>, <a href="https://publications.waset.org/abstracts/search?q=governance" title=" governance"> governance</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20supplier%20selection" title=" sustainable supplier selection"> sustainable supplier selection</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/153736/the-impact-of-governance-criteria-in-the-supplier-selection-process-of-large-german-companies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153736.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">118</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">48</span> Competition for Talent: Retaining Graduates in the Euregio Meuse-Rhine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julia%20Reinold">Julia Reinold</a>, <a href="https://publications.waset.org/abstracts/search?q=Inge%20Hooijen"> Inge Hooijen</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Meng"> Christoph Meng</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Siegel"> Melissa Siegel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates whether or not students intend to stay in the Euregio Meuse-Rhine (EMR) after graduation taking into account the role of hard and soft locational factors, social factors as well as demographic aspects in shaping their mobility preferences. Since graduates are considered a convenient source of human capital in today’s knowledge based economy, it is crucial to understand what drives their mobility intentions in order to retain larger numbers of graduates. This is particularly true for peripheral regions, which need to compete with assumed more attractive economic centres. This paper adds a euregional perspective to the existing literature on graduate migration. Using survey data from 2015 from five higher education institutions in the EMR, this paper finds that mobility intentions are determined by students’ perceptions of the quality of life, openness and career opportunities in the euroregion. In addition, distance to the partner and other social ties such as family and friends influence migration intentions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Euroregion" title="Euroregion">Euroregion</a>, <a href="https://publications.waset.org/abstracts/search?q=graduate%20migration" title=" graduate migration"> graduate migration</a>, <a href="https://publications.waset.org/abstracts/search?q=highly%20skilled%20migration" title=" highly skilled migration"> highly skilled migration</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20capital" title=" human capital"> human capital</a> </p> <a href="https://publications.waset.org/abstracts/47836/competition-for-talent-retaining-graduates-in-the-euregio-meuse-rhine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47836.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">275</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">47</span> On the Transition of Europe’s Power Sector: Economic Consequences of National Targets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Geoffrey%20J.%20Blanford">Geoffrey J.

We apply the EU-REGEN model to explain the penetration of RES from an economic perspective, their spatial distribution, and the complementary role of conventional generation technologies. Furthermore, we identify economic consequences of national energy and climate targets. Our study shows that onshore wind power will be the most crucial generation technology for the future European power sector. Its geographic distribution is driven by resource quality. Gas power will be the major conventional generation technology for backing-up wind power. Moreover, a complete phase out of coal power proves to be not economically optimal. The paper demonstrates that existing national targets have a negative impact, especially on the German region with higher prices and lower revenues. The remaining regions profit are hardly affected. We encourage an EU-wide coordination on the expansion of wind power with harmonized policies. Yet, this requires profitable market structures for both, RES and conventional generation technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=European" title="European">European</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20evaluation" title=" policy evaluation"> policy evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20sector%20investment" title=" power sector investment"> power sector investment</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20choices" title=" technology choices"> technology choices</a> </p> <a href="https://publications.waset.org/abstracts/49101/on-the-transition-of-europes-power-sector-economic-consequences-of-national-targets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49101.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">284</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">46</span> Geographic Information System for District Level Energy Performance Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avichal%20Malhotra">Avichal Malhotra</a>, <a href="https://publications.waset.org/abstracts/search?q=Jerome%20Frisch"> Jerome Frisch</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20van%20Treeck"> Christoph van Treeck</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The utilization of semantic, cadastral and topological data from geographic information systems (GIS) has exponentially increased for building and urban-scale energy performance simulations. Urban planners, simulation scientists, and researchers use virtual 3D city models for energy analysis, algorithms and simulation tools. For dynamic energy simulations at city and district level, this paper provides an overview of the available GIS data models and their levels of detail. Adhering to different norms and standards, these models also intend to describe building and construction industry data. For further investigations, CityGML data models are considered for simulations. Though geographical information modelling has considerably many different implementations, extensions of virtual city data can also be made for domain specific applications. Highlighting the use of the extended CityGML models for energy researches, a brief introduction to the Energy Application Domain Extension (ADE) along with its significance is made. Consequently, addressing specific input simulation data, a workflow using Modelica underlining the usage of GIS information and the quantification of its significance over annual heating energy demand is presented in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CityGML" title="CityGML">CityGML</a>, <a href="https://publications.waset.org/abstracts/search?q=EnergyADE" title=" EnergyADE"> EnergyADE</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20performance%20simulation" title=" energy performance simulation"> energy performance simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a> </p> <a href="https://publications.waset.org/abstracts/107577/geographic-information-system-for-district-level-energy-performance-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107577.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">168</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">45</span> Rotor Concepts for the Counter Flow Heat Recovery Fan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Speer">Christoph Speer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Decentralized ventilation systems should combine a small and economical design with high aerodynamic and thermal efficiency. The Counter Flow Heat Recovery Fan (CHRF) provides the ability to meet these requirements by using only one cross flow fan with a large number of blades to generate both airflows and which simultaneously acts as a regenerative counter flow heat exchanger. The successful development of the first laboratory prototype has shown the potential of this ventilation system. Occurring condensate on the surfaces of the fan blades during the cold and dry season can be recovered through the characteristic mode of operation. Hence the CHRF provides the possibility to avoid the need for frost protection and condensate drain. Through the implementation of system-specific solutions for flow balancing and summer bypass the required functionality is assured. The scalability of the CHRF concept allows the use in renovation as well as in new buildings from single-room devices through to systems for office buildings. High aerodynamic and thermal efficiency and the lower number of required mechatronic components should enable a reduction in investment as well as operating costs. The rotor is the key component of the system, the requirements and possible implementation variants are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CHRF" title="CHRF">CHRF</a>, <a href="https://publications.waset.org/abstracts/search?q=counter%20flow%20heat%20recovery%20fan" title=" counter flow heat recovery fan"> counter flow heat recovery fan</a>, <a href="https://publications.waset.org/abstracts/search?q=decentralized%20ventilation%20system" title=" decentralized ventilation system"> decentralized ventilation system</a>, <a href="https://publications.waset.org/abstracts/search?q=renovation" title=" renovation"> renovation</a> </p> <a href="https://publications.waset.org/abstracts/31420/rotor-concepts-for-the-counter-flow-heat-recovery-fan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31420.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">354</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">44</span> Growing Architecture, Technical Product Harvesting of Near Net Shape Building Components</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Franziska%20Moser">Franziska Moser</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Trautz"> Martin Trautz</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna-Lena%20Beger"> Anna-Lena Beger</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20L%C3%B6wer"> Manuel Löwer</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%B6rg%20Feldhusen"> Jörg Feldhusen</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%BCrgen%20Prell"> Jürgen Prell</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Wormit"> Alexandra Wormit</a>, <a href="https://publications.waset.org/abstracts/search?q=Bj%C3%B6rn%20Usadel"> Björn Usadel</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20K%C3%A4mpfer"> Christoph Kämpfer</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas-Benjamin%20Seiler"> Thomas-Benjamin Seiler</a>, <a href="https://publications.waset.org/abstracts/search?q=Henner%20Hollert"> Henner Hollert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The demand for bio-based materials and components in architecture has increased in recent years due to society’s heightened environmental awareness. Nowadays, most components are being developed via a substitution approach, which aims at replacing conventional components with natural alternatives who are then being processed, shaped and manufactured to fit the desired application. This contribution introduces a novel approach to the development of bio-based products that decreases resource consumption and increases recyclability. In this approach, natural organisms like plants or trees are not being used in a processed form, but grow into a near net shape before then being harvested and utilized as building components. By minimizing the conventional production steps, the amount of resources used in manufacturing decreases whereas the recyclability increases. This paper presents the approach of technical product harvesting, explains the theoretical basis as well as the matching process of product requirements and biological properties, and shows first results of the growth manipulation studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20with%20nature" title="design with nature">design with nature</a>, <a href="https://publications.waset.org/abstracts/search?q=eco%20manufacturing" title=" eco manufacturing"> eco manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20construction%20materials" title=" sustainable construction materials"> sustainable construction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20product%20harvesting" title=" technical product harvesting "> technical product harvesting </a> </p> <a href="https://publications.waset.org/abstracts/26137/growing-architecture-technical-product-harvesting-of-near-net-shape-building-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26137.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">500</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">43</span> Characteristics of Football Spectators Using Second Screen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Florian%20Pfeffel">Florian Pfeffel</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20A.%20Kexel"> Christoph A.

Second Screen describes the use of a second device by television viewers to consume further content which is related to the program they are watching. This study analysed the characteristics of football spectators regarding their media consumption in relation to Second Screen usage while watching a football match on TV. The existing literature on Second Screen usage is still very limited, especially in the context of particular broadcasting settings such as sport or even more specific such as football matches. Therefore, the primary research objective was to reveal first insights into the user behaviour of football spectators regarding Second Screen services. The survey, which was conducted among German football supporters in 2015, revealed some characteristics such as the identification and involvement into the sports which are related to an increased use of Second Screen services. One important finding for football supporters was that at the time of a match they have a lower parallel media usage compared to other TV broadcastings. Nevertheless, if supporters used a second device while watching a match on TV, then they were using specific Second Screen services. This means they searched for more content related information. The findings on the habits and characteristics of people who are using Second Screen services are relevant for future developments in that area as well as for marketing decisions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=media%20consumption" title="media consumption">media consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20screen" title=" second screen"> second screen</a>, <a href="https://publications.waset.org/abstracts/search?q=sport%20marketing" title=" sport marketing"> sport marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20behaviour" title=" user behaviour"> user behaviour</a> </p> <a href="https://publications.waset.org/abstracts/47468/characteristics-of-football-spectators-using-second-screen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47468.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">389</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">42</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.

While the presence of microplastics has been well established in the marine and terrestrial environments, the prevalence of microplastics in the atmosphere is still poorly understood. Wet depositions such as rain or snow scavenge impurities from the atmosphere as it falls to the ground. These wet depositions serve as a useful tool in the removal of airborne particles that are suspended in the air. Therefore, the aim of this study is to investigate the presence of atmospheric microplastics and fibres through the analysis of air, rainwater and snow samples. Air samples were collected with filter-based air samplers from outdoor locations in Singapore. The sampling campaigns were conducted during and after each rain event. Rainwater samples from Singapore and Siberia were collected as well. Snow samples were also collected from Siberia as part of the ongoing study. Genomic DNA was then extracted from the samples and sequenced with shotgun metagenomics approach. qPCR analysis was conducted to quantify the total bacteria and fungi in the air, rainwater and snow samples. The results compared the bioaerosol profiles of all the samples. To observe the presence of microplastics, scanning electron microscope (SEM) was used. From the preliminary results, microplastics were detected. It can be concluded that there is a significant amount of atmospheric microplastics present, and its occurrence should be investigated in greater detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20microplastics" title="atmospheric microplastics">atmospheric microplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=metagenomics" title=" metagenomics"> metagenomics</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscope" title=" scanning electron microscope"> scanning electron microscope</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20deposition" title=" wet deposition"> wet deposition</a> </p> <a href="https://publications.waset.org/abstracts/153093/metagenomics-composition-during-and-after-wet-deposition-and-the-presence-of-airborne-microplastics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153093.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">86</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">40</span> Brain Networks and Mathematical Learning Processes of Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felicitas%20Pielsticker">Felicitas Pielsticker</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Pielsticker"> Christoph Pielsticker</a>, <a href="https://publications.waset.org/abstracts/search?q=Ingo%20Witzke"> Ingo Witzke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Neurological findings provide foundational results for many different disciplines. In this article we want to discuss these with a special focus on mathematics education. The intention is to make neuroscience research useful for the description of cognitive mathematical learning processes. A key issue of mathematics education is that students often behave as if their mathematical knowledge is constructed in isolated compartments with respect to the specific context of the original learning situation; supporting students to link these compartments to form a coherent mathematical society of mind is a fundamental task not only for mathematics teachers. This aspect goes hand in hand with the question if there is such a thing as abstract general mathematical knowledge detached from concrete reality. Educational Neuroscience may give answers to the question why students develop their mathematical knowledge in isolated subjective domains of experience and if it is generally possible to think in abstract terms. To address these questions, we will provide examples from different fields of mathematics education e.g. students’ development and understanding of the general concept of variables or the mathematical notion of universal proofs. We want to discuss these aspects in the reflection of functional studies which elucidate the role of specific brain regions in mathematical learning processes. In doing this the paper addresses concept formation processes of students in the mathematics classroom and how to support them adequately considering the results of (educational) neuroscience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain%20regions" title="brain regions">brain regions</a>, <a href="https://publications.waset.org/abstracts/search?q=concept%20formation%20processes%20in%20mathematics%20education" title=" concept formation processes in mathematics education"> concept formation processes in mathematics education</a>, <a href="https://publications.waset.org/abstracts/search?q=proofs" title=" proofs"> proofs</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching-learning%20processes" title=" teaching-learning processes"> teaching-learning processes</a> </p> <a href="https://publications.waset.org/abstracts/126498/brain-networks-and-mathematical-learning-processes-of-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126498.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">149</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">39</span> Cost Valuation Method for Development Concurrent, Phase Appropriate Requirement Valuation Using the Example of Load Carrier Development in the Lithium-Ion-Battery Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Achim%20Kampker">Achim Kampker</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Deutskens"> Christoph Deutskens</a>, <a href="https://publications.waset.org/abstracts/search?q=Heiner%20Hans%20Heimes"> Heiner Hans Heimes</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Ordung"> Mathias Ordung</a>, <a href="https://publications.waset.org/abstracts/search?q=Felix%20Optehostert"> Felix Optehostert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the past years electric mobility became part of a public discussion. The trend to fully electrified vehicles instead of vehicles fueled with fossil energy has notably gained momentum. Today nearly every big car manufacturer produces and sells fully electrified vehicles, but electrified vehicles are still not as competitive as conventional powered vehicles. As the traction battery states the largest cost driver, lowering its price is a crucial objective. In addition to improvements in product and production processes a non-negligible, but widely underestimated cost driver of production can be found in logistics, since the production technology is not continuous yet and neither are the logistics systems. This paper presents an approach to evaluate cost factors on different designs of load carrier systems. Due to numerous interdependencies, the combination of costs factors for a particular scenario is not transparent. This is effecting actions for cost reduction negatively, but still cost reduction is one of the major goals for simultaneous engineering processes. Therefore a concurrent and phase appropriate cost valuation method is necessary to serve cost transparency. In this paper the four phases of this cost valuation method are defined and explained, which based upon a new approach integrating the logistics development process in to the integrated product and process development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=research%20and%20development" title="research and development">research and development</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20and%20innovation" title=" technology and innovation"> technology and innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion-battery%20production" title=" lithium-ion-battery production"> lithium-ion-battery production</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20carrier%20development%20process" title=" load carrier development process"> load carrier development process</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20valuation%20method" title=" cost valuation method"> cost valuation method</a> </p> <a href="https://publications.waset.org/abstracts/35403/cost-valuation-method-for-development-concurrent-phase-appropriate-requirement-valuation-using-the-example-of-load-carrier-development-in-the-lithium-ion-battery-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35403.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">594</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">38</span> Laser-Hole Boring into Overdense Targets: A Detailed Study on Laser and Target Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Florian%20Wagner">Florian Wagner</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Schmidt"> Christoph Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Bagnoud"> Vincent Bagnoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Understanding the interaction of ultra-intense laser pulses with overcritical targets is of major interest for many applications such as laser-driven ion acceleration, fast ignition in the frame of inertial confinement fusion or high harmonic generation and the creation of attosecond pulses. One particular aspect of this interaction is the shift of the critical surface, where the laser pulse is stopped and the absorption is at maximum, due to the radiation pressure induced by the laser pulse, also referred to as laser hole boring. We investigate laser-hole boring experimentally by measuring the backscattered spectrum which is doppler-broadened because of the movement of the reflecting surface. Using the high-power, high-energy laser system PHELIX in Darmstadt, we gathered an extensive set of data for different laser intensities ranging from 10^18 W/cm2 to 10^21 W/cm2, two different levels of the nanosecond temporal contrast (10^6 vs. 10^11), elliptical and linear polarization and varying target configurations. In this contribution we discuss how the maximum velocity of the critical surface depends on these parameters. In particular we show that by increasing the temporal contrast the maximum hole boring velocity is decreased by more than a factor of three. Our experimental findings are backed by a basic analytical model based on momentum and mass conservation as well as particle in cell simulations. These results are of particular importance for fast ignition since they contribute to a better understanding of the transport of the ignitor pulse into the overdense region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser-hole%20boring" title="laser-hole boring">laser-hole boring</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20of%20ultra-intense%20lasers%20with%20overcritical%20targets" title=" interaction of ultra-intense lasers with overcritical targets"> interaction of ultra-intense lasers with overcritical targets</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20ignition" title=" fast ignition"> fast ignition</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20laser%20motter%20interaction" title=" relativistic laser motter interaction"> relativistic laser motter interaction</a> </p> <a href="https://publications.waset.org/abstracts/45345/laser-hole-boring-into-overdense-targets-a-detailed-study-on-laser-and-target-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45345.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">405</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">37</span> The Hallmarks of War Propaganda: The Case of Russia-Ukraine Conflict</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Veronika%20Solopova">Veronika Solopova</a>, <a href="https://publications.waset.org/abstracts/search?q=Oana-Iuliana%20Popescu"> Oana-Iuliana Popescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Landgraf"> Tim Landgraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Benzm%C3%BCller"> Christoph Benzmüller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Beginning in 2014, slowly building geopolitical tensions in Eastern Europe led to a full-blown conflict between the Russian Federation and Ukraine that generated an unprecedented amount of news articles and data from social media data, reflecting the opposing ideologies and narratives as a background and the essence of the ongoing war. These polarized informational campaigns have led to countless mutual accusations of misinformation and fake news, shaping an atmosphere of confusion and mistrust for many readers all over the world. In this study, we analyzed scraped news articles from Ukrainian, Russian, Romanian and English-speaking news outlets, on the eve of 24th of February 2022, compared to day five of the conflict (28th of February), to see how the media influenced and mirrored the changes in public opinion. We also contrast the sources opposing and supporting the stands of the Russian government in Ukrainian, Russian and Romanian media spaces. In a data-driven way, we describe how the narratives are spread throughout Eastern and Central Europe. We present predictive linguistic features surrounding war propaganda. Our results indicate that there are strong similarities in terms of rhetoric strategies in the pro-Kremlin media in both Ukraine and Russia, which, while being relatively neutral according to surface structure, use aggressive vocabulary. This suggests that automatic propaganda identification systems have to be tailored for each new case, as they have to rely on situationally specific words. Both Ukrainian and Russian outlets lean towards strongly opinionated news, pointing towards the use of war propaganda in order to achieve strategic goals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=linguistic" title="linguistic">linguistic</a>, <a href="https://publications.waset.org/abstracts/search?q=news" title=" news"> news</a>, <a href="https://publications.waset.org/abstracts/search?q=propaganda" title=" propaganda"> propaganda</a>, <a href="https://publications.waset.org/abstracts/search?q=Russia" title=" Russia"> Russia</a>, <a href="https://publications.waset.org/abstracts/search?q=ukraine" title=" ukraine"> ukraine</a> </p> <a href="https://publications.waset.org/abstracts/147825/the-hallmarks-of-war-propaganda-the-case-of-russia-ukraine-conflict" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147825.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">120</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">36</span> Value Creation of Public Financial Management Reforms through Their Long-Term Impacts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Schuler">Christoph Schuler</a>, <a href="https://publications.waset.org/abstracts/search?q=Oriana%20Ponta"> Oriana Ponta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Public Financial Management (PFM) reforms are promoted by various international organizations such as the International Monetary Fund (IMF) or the World Bank, local development banks and the donor country community to strengthen governance and accountability in developing countries across the world. Reform efforts undertaken are often systematically measured against international best practice by the application of standardized analytical instruments such as the Public Expenditure and Financial Accountability Framework (PEFA) or the Poverty Reduction Action Plan (PARP). While those instruments analyze direct achievements of PFM reforms, the long-term benefits of such reforms for society remain untapped. This gives rise to the question why the concept of impact evaluation with its experimental or quasi-experimental settings in the form of randomized control trials has rarely been applied in the context of PFM reforms. To close this gap, this study provides examples where the concept of impact evaluation can be applied to PFM reforms and thereby shifting the focus from outcome towards a long-term impact. As it is a new approach, this study does not attempt to conduct a fully flagged impact evaluation of a certain PFM reform. However, it will outline, as a form of pre-test the applicability of the impact evaluation methodology in this context, for example, by more closely analyzing the commonly used indicators (for example within PEFA or PARP). This would mean to scrutinize these indicators as to how they were designed and how they are related to the long-term impact, they should be producing. The analysis of PFM reform indicators and their relation to long-term impacts should provide practitioners and scholars alike with new insights on how to strengthen the accountability of public service delivery through successful and sustainable PFM reforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accountability" title="accountability">accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20evaluation" title=" impact evaluation"> impact evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=PFM%20reforms" title=" PFM reforms"> PFM reforms</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20financial%20management" title=" public financial management"> public financial management</a> </p> <a href="https://publications.waset.org/abstracts/83774/value-creation-of-public-financial-management-reforms-through-their-long-term-impacts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83774.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">325</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">35</span> Product Architecture and Production Process of Battery Modules from Prismatic Lithium-Ion-Battery Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Achim%20Kampker">Achim Kampker</a>, <a href="https://publications.waset.org/abstracts/search?q=Heiner%20Hans%20Heimes"> Heiner Hans Heimes</a>, <a href="https://publications.waset.org/abstracts/search?q=Nemanja%20Sarovic"> Nemanja Sarovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan-Philip%20Ganser"> Jan-Philip Ganser</a>, <a href="https://publications.waset.org/abstracts/search?q=Saskia%20Wessel"> Saskia Wessel</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Lienemann"> Christoph Lienemann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The electrification of the power train is a fundamental technical transition in the automotive industry and poses a major challenge for established car companies. Providing the traction energy, requiring an ever greater amount of space within the car and having a high share of value-add the lithium-ion battery is a central component of the electric power train and a completely new component to car manufacturers at the same time. Being relatively new to the automotive industry, the current design of the product architecture and production process (including manufacturing and assembling processes) of lithium-ion battery modules do not allow for an easy and cost-efficient disassembly or product design change. Yet these two requirements will increase in importance with rising sales volumes of electric cars in the near future and need to be addressed for the electric car to be competitive with conventional power train systems. This paper focuses on the current product architecture and production process of common automotive battery modules from prismatic lithium-ion battery cells to derive impacts for a remanufacturing concept. The information necessary for this purpose were gathered by literature research, patent inquiries, industry expert interviews and first-hand experiences of the authors. On the basis of these results, the underlying causes for the design´s lack of remanufacturability and flexibility with regards to product design changes are examined. In all, this paper gives an extensive and detailed overview of the state of the art of the product architecture and production process of lithium-ion battery modules from prismatic battery cells, identifies its deficiencies and derives improvement measures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20module" title="battery module">battery module</a>, <a href="https://publications.waset.org/abstracts/search?q=prismatic%20lithium-ion%20battery%20cell" title=" prismatic lithium-ion battery cell"> prismatic lithium-ion battery cell</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20architecture" title=" product architecture"> product architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20process" title=" production process"> production process</a>, <a href="https://publications.waset.org/abstracts/search?q=remanufacturing" title=" remanufacturing"> remanufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility" title=" flexibility"> flexibility</a> </p> <a href="https://publications.waset.org/abstracts/78338/product-architecture-and-production-process-of-battery-modules-from-prismatic-lithium-ion-battery-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78338.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">267</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">34</span> A Review on Benzo(a)pyrene Emission Factors from Biomass Combustion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Franziska%20Klauser">Franziska Klauser</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Schwabl"> Manuel Schwabl</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Weissinger"> Alexander Weissinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Schmidl"> Christoph Schmidl</a>, <a href="https://publications.waset.org/abstracts/search?q=Walter%20Haslinger"> Walter Haslinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Anne%20Kasper-Giebl"> Anne Kasper-Giebl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Benzo(a)pyrene (BaP) is the most widely investigated representative of Polycyclic Aromatic Hydrocarbons (PAH) as well as one of the most toxic compounds in this group. Since 2013 in the European Union a limit value for BaP concentration in the ambient air is applied, which was set to a yearly average value of 1 ng m-3. Several reports show that in some regions, even where industry and traffic are of minor impact this threshold is regularly exceeded. This is taken as proof that biomass combustion for heating purposes contributes significantly to BaP pollution. Several investigations have been already carried out on the BaP emission behavior of biomass combustion furnaces, mostly focusing on a certain aspect like the influences from wood type, of operation type or of technology type. However, a superior view on emission patterns of BaP from biomass combustion and the aggregation of determined values also from recent studies is not presented so far. The combination of determined values allows a better understanding of the BaP emission behavior from biomass combustion. In this work the review conclusions are driven from the combination of outcomes from different publication. In two examples it was shown that technical progress leads to 10 to 100 fold lower BaP emission from modern furnaces compared to old technologies of equivalent type. It was also indicated that the operation with pellets or wood chips exhibits clearly lower BaP emission factors compared to operation with log wood. Although, the BaP emission level from automatic furnaces is strongly impacted by the kind of operation. This work delivers an overview on BaP emission factors from different biomass combustion appliances, from different operation modes and from the combustion of different fuel and wood types. The main impact factors are depicted, and suggestions for low BaP emission biomass combustion are derived. As one result possible investigation fields concerning BaP emissions from biomass combustion that seem to be most important to be clarified are suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benzo%28a%29pyrene" title="benzo(a)pyrene">benzo(a)pyrene</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion" title=" combustion"> combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=emission" title=" emission"> emission</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a> </p> <a href="https://publications.waset.org/abstracts/58928/a-review-on-benzoapyrene-emission-factors-from-biomass-combustion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58928.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">355</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">33</span> Modelling the Effect of Biomass Appropriation for Human Use on Global Biodiversity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karina%20Reiter">Karina Reiter</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Dullinger"> Stefan Dullinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Plutzar"> Christoph Plutzar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dietmar%20Moser"> Dietmar Moser</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to population growth and changing patterns of production and consumption, the demand for natural resources and, as a result, the pressure on Earth’s ecosystems are growing. Biodiversity mapping can be a useful tool for assessing species endangerment or detecting hotspots of extinction risks. This paper explores the benefits of using the change in trophic energy flows as a consequence of the human alteration of the biosphere in biodiversity mapping. To this end, multiple linear regression models were developed to explain species richness in areas where there is no human influence (i.e. wilderness) for three taxonomic groups (birds, mammals, amphibians). The models were then applied to predict (I) potential global species richness using potential natural vegetation (NPPpot) and (II) global ‘actual’ species richness after biomass appropriation using NPP remaining in ecosystems after harvest (NPPeco). By calculating the difference between predicted potential and predicted actual species numbers, maps of estimated species richness loss were generated. Results show that biomass appropriation for human use can indeed be linked to biodiversity loss. Areas for which the models predicted high species loss coincide with areas where species endangerment and extinctions are recorded to be particularly high by the International Union for Conservation of Nature and Natural Resources (IUCN). Furthermore, the analysis revealed that while the species distribution maps of the IUCN Red List of Threatened Species used for this research can determine hotspots of biodiversity loss in large parts of the world, the classification system for threatened and extinct species needs to be revised to better reflect local risks of extinction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity%20loss" title="biodiversity loss">biodiversity loss</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20harvest" title=" biomass harvest"> biomass harvest</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20appropriation%20of%20net%20primary%20production" title=" human appropriation of net primary production"> human appropriation of net primary production</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20richness" title=" species richness"> species richness</a> </p> <a href="https://publications.waset.org/abstracts/106794/modelling-the-effect-of-biomass-appropriation-for-human-use-on-global-biodiversity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106794.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">130</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> Protective Coating Layers via Phosphazene Compounds for Stabilizing Silicon Anode Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adjmal%20Ghaur">Adjmal Ghaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Peschel"> Christoph Peschel</a>, <a href="https://publications.waset.org/abstracts/search?q=Iris%20Dienwiebel"> Iris Dienwiebel</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukas%20Haneke"> Lukas Haneke</a>, <a href="https://publications.waset.org/abstracts/search?q=Leilei%20Du"> Leilei Du </a>, <a href="https://publications.waset.org/abstracts/search?q=Laurin%20Profanter">Laurin Profanter</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Placke"> Tobias Placke</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Winter"> Martin Winter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, lithium-ion batteries (LIBs)are widely used in electric vehicles (EVs) and mobile energy storage devices (ESDs), which has led to higher requirements for energy density. To fulfill these requirements, tremendous attention has been paid to design advanced LIBs with various siliconactive materials as alternative negative electrodes to replace graphite (372 mAh g⁻¹)due to their high theoretical gravimetric capacity (4200mAh g⁻¹). However, silicon as potential anode material suffers from huge volume changes during charging and discharging and has poor electronicconductivity which negatively impacts the long-term performance and preventshigh silicon contents from practical application. Additionally, an unstable crystalline silicon structure tends to pulverization during the (de)lithiation process. To compensate for the volume changes, alleviate pulverization, and maintain high electronicconductivity, silicon-doped graphite composites with protecting coating layers are a promising approach. In this context, phosphazene compounds are investigated concerning their silicon protecting properties in silicon-doped graphite composites. In detail, electrochemical performance measurements in pouch full-cells(NCM523||SiOx/C), supressing gas formation properties, and post-mortem analyzes were carried out to characterize phosphazene compounds as additive materials. The introduction of the dual-additive approach in state-of-the-art electrolytes leads to synergistic effects between FEC and phosphazene compounds which accelerate the durability of silicon particles and results in enhanced electrochemical performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silicon" title="silicon">silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphazene" title=" phosphazene"> phosphazene</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20electrolyte%20interphase" title=" solid electrolyte interphase"> solid electrolyte interphase</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolyte" title=" electrolyte"> electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=gasmeasurements" title=" gasmeasurements"> gasmeasurements</a> </p> <a href="https://publications.waset.org/abstracts/145116/protective-coating-layers-via-phosphazene-compounds-for-stabilizing-silicon-anode-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145116.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">166</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> Brain-Computer Interface System for Lower Extremity Rehabilitation of Chronic Stroke Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marc%20Sebasti%C3%A1n-Romagosa">Marc Sebastián-Romagosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Woosang%20Cho"> Woosang Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Rupert%20Ortner"> Rupert Ortner</a>, <a href="https://publications.waset.org/abstracts/search?q=Christy%20Li"> Christy Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Guger"> Christoph Guger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Neurorehabilitation based on Brain-Computer Interfaces (BCIs) shows important rehabilitation effects for patients after stroke. Previous studies have shown improvements for patients that are in a chronic stage and/or have severe hemiparesis and are particularly challenging for conventional rehabilitation techniques. For this publication, seven stroke patients in the chronic phase with hemiparesis in the lower extremity were recruited. All of them participated in 25 BCI sessions about 3 times a week. The BCI system was based on the Motor Imagery (MI) of the paretic ankle dorsiflexion and healthy wrist dorsiflexion with Functional Electrical Stimulation (FES) and avatar feedback. Assessments were conducted to assess the changes in motor improvement before, after and during the rehabilitation training. Our primary measures used for the assessment were the 10-meters walking test (10MWT), Range of Motion (ROM) of the ankle dorsiflexion and Timed Up and Go (TUG). Results show a significant increase in the gait speed in the primary measure 10MWT fast velocity of 0.18 m/s IQR = [0.12 to 0.2], P = 0.016. The speed in the TUG was also significantly increased by 0.1 m/s IQR = [0.09 to 0.11], P = 0.031. The active ROM assessment increased 4.65º, and IQR = [ 1.67 - 7.4], after rehabilitation training, P = 0.029. These functional improvements persisted at least one month after the end of the therapy. These outcomes show the feasibility of this BCI approach for chronic stroke patients and further support the growing consensus that these types of tools might develop into a new paradigm for rehabilitation tools for stroke patients. However, the results are from only seven chronic stroke patients, so the authors believe that this approach should be further validated in broader randomized controlled studies involving more patients. MI and FES-based non-invasive BCIs are showing improvement in the gait rehabilitation of patients in the chronic stage after stroke. This could have an impact on the rehabilitation techniques used for these patients, especially when they are severely impaired and their mobility is limited. <p
