logistic objectives such as ‘delivery reliability’ and ‘delivery time’ and distribution’s logistic objectives such as ‘service level’ and ‘delivery delay’ are attributed great importance. Especially for small and mid-sized enterprises (SME) attaining these objectives pose a key challenge. Within this context, one of the difficulties is that interactions between departments within the enterprise and their specific objectives are insufficiently taken into account and aligned. Interdepartmental independencies along with contradicting targets set within the different departments result in enterprises having sub-optimal logistic performance capability. This paper presents a research project which will systematically describe the interactions between departments and convert them into a quantifiable form. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=department-specific%20actuating%20and%20control%20variables" title="department-specific actuating and control variables">department-specific actuating and control variables</a>, <a href="https://publications.waset.org/abstracts/search?q=interdepartmental%20interactions" title=" interdepartmental interactions"> interdepartmental interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=cybernetic%20model" title=" cybernetic model"> cybernetic model</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20objectives" title=" logistic objectives"> logistic objectives</a> </p> <a href="https://publications.waset.org/abstracts/10592/developing-a-cybernetic-model-of-interdepartmental-logistic-interactions-in-sme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10592.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">372</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">53</span> Energy Unchained: An Analysis of Affordances of the Blockchain Technology in the Energy Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Kahlert">Jonas Kahlert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blockchain technology has gained importance and momentum in the energy sector. Yet, there is no structured analysis of how specific features of the blockchain technology can create value in the energy sector. We employ a qualitative analysis on insights gained from the current literature and expert interviews. Along the four most prevalent use cases of blockchain technology in the energy sector, we discuss the potential of blockchain technology to support a transition to a more affordable, sustainable and reliable energy system. We show that in its current state, blockchain and adjacent technologies are not a necessity but a sufficiency towards this transition. We also show how current limitations of the blockchain and adjacent technologies can be even counterproductive. Finally, we discuss implications for policy makers and managers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain%20technology" title="blockchain technology">blockchain technology</a>, <a href="https://publications.waset.org/abstracts/search?q=affordance%20theory" title=" affordance theory"> affordance theory</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20trilemma" title=" energy trilemma"> energy trilemma</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/71781/energy-unchained-an-analysis-of-affordances-of-the-blockchain-technology-in-the-energy-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71781.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">484</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">52</span> Performance Analysis of a 6-Phase PMG Exciter with Rotating Thyristor-Controlled Rectification Topologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Kristiansen%20N%C3%B8land">Jonas Kristiansen Nøland</a>, <a href="https://publications.waset.org/abstracts/search?q=Karina%20Hjelmervik"> Karina Hjelmervik</a>, <a href="https://publications.waset.org/abstracts/search?q=Urban%20Lundin"> Urban Lundin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The thyristor bridge rectifier is often used for control of excitation equipment for synchronous generators. However, on the rotating shaft of brushless exciters, the diode bridge rectifier is mostly used. The step response of a conventional brushless rotating excitation system is slow compared to static excitation systems. This paper investigates the performance of different thyristor-controlled rectification topologies applied on the shaft of a 6-phase PMG exciter connected to a synchronous generator.

In doing so, the orientation on customer wishes (e.g. delivery dates) represents a key parameter not only in the value-adding production but also in product regeneration. Since production and regeneration processes have different characteristics, production planning and control measures cannot be directly transferred to regeneration processes. As part of a special research project, the Institute of Production Systems and Logistics Hannover is focused on increasing the logistic performance capability of regeneration processes for complex capital goods. The aim is to ensure logistic targets are met by implementing a model specifically designed to align the capacities and load in regeneration processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacity%20planning" title="capacity planning">capacity planning</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20capital%20goods" title=" complex capital goods"> complex capital goods</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20performance" title=" logistic performance"> logistic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration%20process" title=" regeneration process"> regeneration process</a> </p> <a href="https://publications.waset.org/abstracts/10591/evaluating-the-logistic-performance-capability-of-regeneration-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10591.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">489</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> Technology Blending as an Innovative Construction Mechanism in the Global South</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Janet%20Kaningen">Janet Kaningen</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20N.%20Kaningen"> Richard N.

Advances in material science, building component production, and assembly technologies are leading to the development of next-generation materials such as polymeric-fiber-based products, light-metal alloys, and eco-materials. Modular housing construction has become more efficient and cost-effective than traditional building methods and is becoming increasingly popular for commercial, industrial, and residential projects.

The general liberalization process that the countries has undergone together has convinced the governments of the member states of need to upgrade their economic and training systems in order to be able to face the economic globalization. Several signs of economic convergence have been found but less is known about the knowledge production. This paper addresses the convergence pattern of technological innovation in 13 European Union (EU) states over the time period 1990-2011 by means of parametric and non-parametric techniques. Parametric approaches revolve around the neoclassical convergence theories. This paper reveals divergence of both the β and σ types. Further, we found evidence of stochastic divergence and non-parametric convergence approach such as distribution dynamics shows a tendency towards divergence. This result is supported with the occurrence of γ-divergence. The policies of the EU to reduce technological gap among its member states seem to be missing its target, something that can have negative long run consequences for the market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convergence" title="convergence">convergence</a>, <a href="https://publications.waset.org/abstracts/search?q=patents" title=" patents"> patents</a>, <a href="https://publications.waset.org/abstracts/search?q=panel%20data" title=" panel data"> panel data</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20union" title=" European union"> European union</a> </p> <a href="https://publications.waset.org/abstracts/7910/divergence-of-innovation-capabilities-within-the-eu" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7910.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">287</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> Resilience Grit and Intrinsic Motivation Are Predictors of Better Studying Results among First-year Cadets in the Cadet Basic Training Course</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosita%20Kanapeckaite">Rosita Kanapeckaite</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every year, some candidates who enroll in Generolas Jonas Zemaitis Military Academy of Lithuania do not complete a basic seven weeks cadet course and leave the Academy. Experience in other countries shows that psychological resilience grit and intrinsic motivation can lead to better course completion results. We examined the psychological resilience grit and intrinsic motivation as predictors of better results among newcomers who participate in the Cadet Basic Training (CBT) course. Based on past research and theory of other countries' military academies, we expected that resilience grit, and intrinsic motivation would predict performance in the Cadet Basic Training course. Results of regression analyses revealed that resilience and grit can predict better course results, but intrinsic motivation can not predict retention. These findings suggest that resilience and grit assessment and training may prove valuable in enhancing performance and retention within military training environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=military" title="military">military</a>, <a href="https://publications.waset.org/abstracts/search?q=intrinsic%20motivation" title=" intrinsic motivation"> intrinsic motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=grit" title=" grit"> grit</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/143469/resilience-grit-and-intrinsic-motivation-are-predictors-of-better-studying-results-among-first-year-cadets-in-the-cadet-basic-training-course" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143469.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">209</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> Computational Approaches for Ballistic Impact Response of Stainless Steel 304</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Mostafa">A.

The simulated ballistic impact tests were conducted on clamped sheets with different thicknesses using ABAQUS/Explicit nonlinear finite element (FE) package. The ballistic limit velocity was determined using three approaches, namely: numerical tests based on material properties, FE calculated residual velocities and FE calculated residual energies. Johnson-Cook plasticity and failure criterion were utilized to simulate the dynamic behaviour of the SS 304 under various strain rates, while the well-known Lambert-Jonas equation was used for the data regression for the residual velocity and energy model. Good agreement between the investigated numerical methods was achieved. Additionally, the dependence of the ballistic limit velocity on the sheet thickness was observed.

The effects of socioeconomic status on academic motivation are conceptualized according to Bourdieu’s habitus concept, reflecting the role of unconscious and internalized cultural signals, proper to low and high socioeconomic status family contexts. Since families differ by various socioeconomic features, the hypothesis about possible impact of parents’ socioeconomic status on their children’s academic motivation interfering with gender socialization effects is held. The survey, aiming to seize gender differences in academic motivation and self-recorded improvement-oriented efforts as a result of socialization processes operating in the families of low and high socioeconomic status, was designed. The results of Lithuanian higher education students’ survey are presented and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20motivation" title="academic motivation">academic motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=socialization" title=" socialization"> socialization</a>, <a href="https://publications.waset.org/abstracts/search?q=socioeconomic%20status" title=" socioeconomic status"> socioeconomic status</a> </p> <a href="https://publications.waset.org/abstracts/13764/the-effects-of-gender-and-socioeconomic-status-on-academic-motivation-the-case-of-lithuania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13764.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">396</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> Home Owner Focused Investment Analysis Tool for Energy Refurbishment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Hinker">Jonas Hinker</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Zumholz"> Lisa Zumholz</a>, <a href="https://publications.waset.org/abstracts/search?q=Johanna%20M.%20A.%20Myrzik"> Johanna M.

As the mandatory standards for residential retrofits are well-balanced in such a way that strict adherence to them guarantees profit from the investment, it becomes difficult to explain the reasons why there are so many people hesitant with their investments. Risks and transaction costs can be understood as socio-technical boundaries and have to be taken into consideration to be able to understand why a worthwhile investment is postponed or rejected. This paper therefore presents a method for investment analyses that is focused on such socio-technical constraints, which helps to reveal the strongest misconceptions of home owners. By depicting sensitivities and risk factors in an integrated and impartial way, such a tool can be utilized by home owners to address reservations and misunderstandings. In the end, this leads to an exploitation of smaller energy efficiency measures that makes up a big demand reduction in the residential sector altogether. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20refurbishment" title="energy refurbishment">energy refurbishment</a>, <a href="https://publications.waset.org/abstracts/search?q=investment%20analysis" title=" investment analysis"> investment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20buildings" title=" residential buildings"> residential buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=risk-aware%20investment%20strategy" title=" risk-aware investment strategy"> risk-aware investment strategy</a> </p> <a href="https://publications.waset.org/abstracts/34733/home-owner-focused-investment-analysis-tool-for-energy-refurbishment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34733.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">531</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> Alternative Coating Compositions by Thermal Arc Spraying to Improve the Contact Heat Treatment in Press Hardening</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Burger">Philipp Burger</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Sommer"> Jonas Sommer</a>, <a href="https://publications.waset.org/abstracts/search?q=Haneen%20Daoud"> Haneen Daoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Franz%20Hilmer"> Franz Hilmer</a>, <a href="https://publications.waset.org/abstracts/search?q=Uwe%20Glatzel"> Uwe Glatzel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Press-hardened structural components made of coated high-strength steel are an essential part of the automotive industry when it comes to weight reduction, safety, and durability. 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">42</span> Analysis of the Suspension Rocker of Formula SAE Prototype by Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jessyca%20A.%20Bessa">Jessyca A.

This is a device of the suspension of Formula SAE vehicle that receives efforts from the motion scrolling of the vehicle and transmits them to the chassis frame minimized by a momentum ratio and smoothed by the set spring - damper. A review of parameters used in vehicle dynamics and a geometric analysis of the forces and stresses caused by such was carried out. The main function of the rocker is to reduce the force transmitted to the frame due to movement of rolling and subsequent application of the suspension. This functions is taken as satisfactory, since the force applied to the wheel and which would be transmitted to the chassis is reduced from 3833.9N to 3496.48N. From these values can be further more detailed simulations using the finite element method aimed at mass reduction or even rocker manufacturing feasibility aluminum. Then, the analysis by the finite element method was applied. This analysis uses the theory of discretization of systems and examines the strength of the component based on the distortion energy, determining the maximum straining experienced by the component and the region of higher demand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rocker" title="rocker">rocker</a>, <a href="https://publications.waset.org/abstracts/search?q=suspension" title=" suspension"> suspension</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20finite%20element%20method" title=" the finite element method"> the finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=mechatronics%20engineering" title=" mechatronics engineering"> mechatronics engineering</a> </p> <a href="https://publications.waset.org/abstracts/21242/analysis-of-the-suspension-rocker-of-formula-sae-prototype-by-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21242.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">541</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">41</span> Design and Implementation of a Monitoring System Using Arduino and MATLAB</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20P.%20Reges">Jonas P.

This research brought several unknowns that were resolved from bibliographical research. Based on the studies performed were found some monitoring methods, including the serial communication between the arduino and matlab which showed a great option due to the low cost. The project was conducted in two stages, the first, an algorithm was developed to the Arduino and Matlab, and second, the circuits were assembled and performed the monitoring tests the following variables: moisture, temperature, and distance. During testing it was possible to momentarily observe the change in the levels of monitored variables. The project showed satisfactory results, such as: real-time verification of the change of state variables, the low cost of acquisition of the prototype, possibility of easy change of programming for the execution of monitoring of other variables. Therefore, the project showed the possibility of monitoring through software and hardware that have easy programming and can be used in several areas. However, it is observed also the possibility of improving the project from a remote monitoring via Bluetooth or web server and through the control of monitored variables. <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=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=programming" title=" programming"> programming</a>, <a href="https://publications.waset.org/abstracts/search?q=arduino" title=" arduino"> arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=matlab" title=" matlab"> matlab</a> </p> <a href="https://publications.waset.org/abstracts/21165/design-and-implementation-of-a-monitoring-system-using-arduino-and-matlab" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21165.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">517</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> A Review on Future Safety Conditions and Requirements for E-Bikes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Palmer">Jonas Palmer</a>, <a href="https://publications.waset.org/abstracts/search?q=Leon%20Br%C3%BCning"> Leon Brüning</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukas%20Himmelsbach"> Lukas Himmelsbach</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The worldwide ambitions to transform the transportation sector are increasingly affecting the safety conditions for all traffic participants and the required infrastructure. To contribute to the transformation and for health aspects, individuals search for carbon-free alternatives that include physical excitation. Especially e-bikes experience a growing demand within the last few years and consequently change the safety requirements. E-cyclists are exposed to amplified risks due to higher velocity in comparison to classic cyclists. Furthermore, cyclists suffer from a lack of infrastructure, rider assistance systems as well as awareness of other road users. For minimizing the risk of accidents, it is crucial to identify, develop and implement safety measures for cyclists. The paper aims to contribute to future research with delivering an overview of the latest publications and to subsequently identify essential research gaps. Therefore, it is essential to analyze the areas of technical adjustments as well as legal aspects and the correlation of both. The review`s insights can intensify the awareness of safety issues related to e-bikes and promote the development and implementation of appropriate measures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-bike%20safety%20measures" title="e-bike safety measures">e-bike safety measures</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20mobility" title=" future mobility"> future mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a> </p> <a href="https://publications.waset.org/abstracts/165222/a-review-on-future-safety-conditions-and-requirements-for-e-bikes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165222.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">116</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> Data Modeling and Calibration of In-Line Pultrusion and Laser Ablation Machine Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20F.%20Nettleton">David F.

The end product of the processes is the core of a medical guidewire, manufactured to comply with a user specification of diameter and flexibility. An ensemble approach is followed which requires training several models. Two state of the art machine learning algorithms are benchmarked: Kernel Recursive Least Squares (KRLS) and Support Vector Regression (SVR). The final objective is to build a precise digital model of the pultrusion and laser ablation process in order to calibrate the resulting diameter and flexibility of a medical guidewire, which is the end product while taking into account the friction on the forming die. The result is an ensemble of models, whose output is within a strict required tolerance and which covers the required range of diameter and flexibility of the guidewire end product.

Submerged aquatic vegetation, also known as SAV, forms an important part of ecologically healthy river systems. Direct and indirect human influences, such as climate change are putting stress on aquatic plant communities, ranging from the invasion of non-native species and grazing, to changes in the river flow conditions and temperature. There is a need to monitor SAV, because they are in a state of deterioration and their disappearance will greatly impact river ecosystems. Like terrestrial plants, SAV can show visible signs of stress. However, the techniques used to map terrestrial vegetation from its spectral reflectance, are not easily transferable to a submerged environment. Optical remote sensing techniques are employed to detect the stress from remotely sensed images through multispectral imagery and Structure from Motion photogrammetry. The effect of the overlying water column in the form of refraction, attenuation of visible and near infrared bands in water, as well as highly moving targets, are NIR) key challenges that arise when remotely mapping SAV. This study looks into the possibility of mapping the changes in spectral signatures from SAV and their response to certain stresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=submerged%20aquatic%20vegetation" title="submerged aquatic vegetation">submerged aquatic vegetation</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20from%20motion" title=" structure from motion"> structure from motion</a>, <a href="https://publications.waset.org/abstracts/search?q=photogrammetry" title=" photogrammetry"> photogrammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=multispectral" title=" multispectral"> multispectral</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopy" title=" spectroscopy"> spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/174497/mapping-stress-in-submerged-aquatic-vegetation-using-multispectral-imagery-and-structure-from-motion-photogrammetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174497.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">101</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> Theology of Science and Technology as a Tool for Peace Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Chikelue%20Ogbuefi">Jonas Chikelue Ogbuefi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Science and Technology have a major impact on societal peace, it offers support to teaching and learning, cuts costs, and offers solutions to the current agitations and militancy in Nigeria today. Christianity, for instance, did not only change and form the western world in the past 2022 but still has a substantial role to play in society through liquid ecclesiology. This paper interrogated the impact of the theology of Science and Technology as a tool for peace sustainability through peace education in Nigeria. The method adopted is a historical and descriptive method of analysis. It was discovered that a larger number of Nigerian citizens lack almost all the basic things needed for the standard of living, such as Shelter, meaningful employment, and clothing, which is the root course of all agitations in Nigeria. Based on the above findings, the paper contends that the government alone cannot restore Peace in Nigeria. Hence the inability of the government to restore peace calls for all religious actors to be involved. The main thrust and recommendation of this paper are to challenge the religious actors to implement the Theology of Science and Technology as a tool for peace restoration and should network with both the government and the private sectors to make funds available to budding and existing entrepreneurs using Science and Technology as a tool for Peace and economic sustainability. This paper viewed the theology of Science and Technology as a tool for Peace and economic sustainability in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=theology" title="theology">theology</a>, <a href="https://publications.waset.org/abstracts/search?q=science" title=" science"> science</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=peace%20education" title=" peace education"> peace education</a> </p> <a href="https://publications.waset.org/abstracts/161372/theology-of-science-and-technology-as-a-tool-for-peace-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161372.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">84</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> DesignChain: Automated Design of Products Featuring a Large Number of Variants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lars%20R%C3%B6del">Lars Rödel</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Krebs"> Jonas Krebs</a>, <a href="https://publications.waset.org/abstracts/search?q=Gregor%20M%C3%BCller"> Gregor Müller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The growing price pressure due to the increasing number of global suppliers, the growing individualization of products and ever-shorter delivery times are upcoming challenges in the industry. In this context, Mass Personalization stands for the individualized production of customer products in batch size 1 at the price of standardized products. The possibilities of digitalization and automation of technical order processing open up the opportunity for companies to significantly reduce their cost of complexity and lead times and thus enhance their competitiveness. Many companies already use a range of CAx tools and configuration solutions today. Often, the expert knowledge of employees is hidden in "knowledge silos" and is rarely networked across processes. DesignChain describes the automated digital process from the recording of individual customer requirements, through design and technical preparation, to production. Configurators offer the possibility of mapping variant-rich products within the Design Chain. This transformation of customer requirements into product features makes it possible to generate even complex CAD models, such as those for large-scale plants, on a rule-based basis. With the aid of an automated CAx chain, production-relevant documents are thus transferred digitally to production. This process, which can be fully automated, allows variants to always be generated on the basis of current version statuses. <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=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD" title=" CAD"> CAD</a>, <a href="https://publications.waset.org/abstracts/search?q=CAx" title=" CAx"> CAx</a> </p> <a href="https://publications.waset.org/abstracts/162340/designchain-automated-design-of-products-featuring-a-large-number-of-variants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162340.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">35</span> Brain Tumor Segmentation Based on Minimum Spanning Tree</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simeon%20Mayala">Simeon Mayala</a>, <a href="https://publications.waset.org/abstracts/search?q=Ida%20Herdlev%C3%A6r"> Ida Herdlevær</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Bull%20Haugs%C3%B8en"> Jonas Bull Haugsøen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shamundeeswari%20Anandan"> Shamundeeswari Anandan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Gavasso"> Sonia Gavasso</a>, <a href="https://publications.waset.org/abstracts/search?q=Morten%20Brun"> Morten Brun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose a minimum spanning tree-based method for segmenting brain tumors. The proposed method performs interactive segmentation based on the minimum spanning tree without tuning parameters. The steps involve preprocessing, making a graph, constructing a minimum spanning tree, and a newly implemented way of interactively segmenting the region of interest. In the preprocessing step, a Gaussian filter is applied to 2D images to remove the noise. Then, the pixel neighbor graph is weighted by intensity differences and the corresponding minimum spanning tree is constructed. The image is loaded in an interactive window for segmenting the tumor. The region of interest and the background are selected by clicking to split the minimum spanning tree into two trees. One of these trees represents the region of interest and the other represents the background. Finally, the segmentation given by the two trees is visualized. The proposed method was tested by segmenting two different 2D brain T1-weighted magnetic resonance image data sets. The comparison between our results and the standard gold segmentation confirmed the validity of the minimum spanning tree approach. The proposed method is simple to implement and the results indicate that it is accurate and efficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brain%20tumor" title="brain tumor">brain tumor</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20tumor%20segmentation" title=" brain tumor segmentation"> brain tumor segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20spanning%20tree" title=" minimum spanning tree"> minimum spanning tree</a>, <a href="https://publications.waset.org/abstracts/search?q=segmentation" title=" segmentation"> segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a> </p> <a href="https://publications.waset.org/abstracts/148591/brain-tumor-segmentation-based-on-minimum-spanning-tree" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148591.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">122</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> Technologic Information about Photovoltaic Applied in Urban Residences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Fabris%20Russo">Stephanie Fabris Russo</a>, <a href="https://publications.waset.org/abstracts/search?q=Daiane%20Costa%20Guimar%C3%A3es"> Daiane Costa Guimarães</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Pedro%20Fabris"> Jonas Pedro Fabris</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Emilia%20Camargo"> Maria Emilia Camargo</a>, <a href="https://publications.waset.org/abstracts/search?q=Suzana%20Leit%C3%A3o%20Russo"> Suzana Leitão Russo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Augusto%20Andrade%20Filho"> José Augusto Andrade Filho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among renewable energy sources, solar energy is the one that has stood out. Solar radiation can be used as a thermal energy source and can also be converted into electricity by means of effects on certain materials, such as thermoelectric and photovoltaic panels. These panels are often used to generate energy in homes, buildings, arenas, etc., and have low pollution emissions. Thus, a technological prospecting was performed to find patents related to the use of photovoltaic plates in urban residences. The patent search was based on ESPACENET, associating the keywords photovoltaic and home, where we found 136 patent documents in the period of 1994-2015 in the fields title and abstract. Note that the years 2009, 2010, 2011, 2012, 2013 and 2014 had the highest number of applicants, with respectively, 11, 13, 23, 29, 15 and 21. Regarding the country that deposited about this technology, it is clear that China leads with 67 patent deposits, followed by Japan with 38 patents applications. It is important to note that most depositors, 50% are companies, 44% are individual inventors and only 6% are universities. On the International Patent classification (IPC) codes, we noted that the most present classification in results was H02J3/38, which represents provisions in parallel to feed a single network by two or more generators, converters or transformers. Among all categories, there is the H session, which means Electricity, with 70% of the patents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title="photovoltaic">photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20residences" title=" urban residences"> urban residences</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20forecasting" title=" technology forecasting"> technology forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=prospecting" title=" prospecting"> prospecting</a> </p> <a href="https://publications.waset.org/abstracts/53664/technologic-information-about-photovoltaic-applied-in-urban-residences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53664.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">301</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> Parabens, Paraben Metabolites and Triclocarban in Sediment Samples from the Trondheim Fjord, Norway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kristine%20Vike-Jonas">Kristine Vike-Jonas</a>, <a href="https://publications.waset.org/abstracts/search?q=Susana%20V.%20Gonzalez"> Susana V.

The aim of this study was to investigate the levels of these compounds in sediment near the effluent of a wastewater treatment plant (WWTP) in the Trondheim Fjord, Norway. Paraben, paraben metabolites, and TCC are high volume production chemicals that are found in a range of consumer products, especially pharmaceuticals and personal care products (PCPs). In this study, six parabens (methyl paraben; MeP, ethyl paraben; EtP, propyl paraben; PrP, butyl paraben; BuP, benzyl paraben; BezP, heptyl paraben; HeP), four paraben metabolites (4-hydroxybenzoic acid; 4-HB, 3,4-dihydroxybenzoic acid; 3,4-DHB, methyl protocatechuic acid; OH-MeP, ethyl protocatechuic acid; OH-EtP) and TCC were determined by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) in 64 sediment samples from 10 different locations outside Trondheim, Norway. Of these 11 target analytes, four were detected in 40 % or more of the samples. The sum of six parabens (∑Parabens), four paraben metabolites (∑Metabolites) and TCC in sediment ranged from 4.88 to 11.56 (mean 6.81) ng/g, 52.16 to 368.28 (mean 93.89) ng/g and 0.53 to 3.65 (mean 1.50) ng/g dry sediment, respectively. Pearson correlation coefficients indicated that TCC was positively correlated with OH-MeP, but negatively correlated with 4-HB. To the best of the author’s knowledge, this is the first time parabens, paraben metabolites and TCC have been reported in the Trondheim Fjord. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parabens" title="parabens">parabens</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20chromatography" title=" liquid chromatography"> liquid chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=tandem%20mass%20spectrometry" title=" tandem mass spectrometry"> tandem mass spectrometry</a> </p> <a href="https://publications.waset.org/abstracts/113904/parabens-paraben-metabolites-and-triclocarban-in-sediment-samples-from-the-trondheim-fjord-norway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113904.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">129</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> Alpha: A Groundbreaking Avatar Merging User Dialogue with OpenAI's GPT-3.5 for Enhanced Reflective Thinking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Colin">Jonas Colin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Standing at the vanguard of AI development, Alpha represents an unprecedented synthesis of logical rigor and human abstraction, meticulously crafted to mirror the user's unique persona and personality, a feat previously unattainable in AI development. Alpha, an avant-garde artefact in the realm of artificial intelligence, epitomizes a paradigmatic shift in personalized digital interaction, amalgamating user-specific dialogic patterns with the sophisticated algorithmic prowess of OpenAI's GPT-3.5 to engender a platform for enhanced metacognitive engagement and individualized user experience. Underpinned by a sophisticated algorithmic framework, Alpha integrates vast datasets through a complex interplay of neural network models and symbolic AI, facilitating a dynamic, adaptive learning process. This integration enables the system to construct a detailed user profile, encompassing linguistic preferences, emotional tendencies, and cognitive styles, tailoring interactions to align with individual characteristics and conversational contexts. Furthermore, Alpha incorporates advanced metacognitive elements, enabling real-time reflection and adaptation in communication strategies.

Rejikumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reducing post-harvest losses could be a sustainable solution to enhance the food and income security of smallholder farmers in developing countries. While various research institutions have come up with a number of innovative post-harvest technologies for reducing post-harvest losses, most of them have not been extensively adopted by smallholder farmers. Despite this gap, the synthesized information about the major constraints of post-harvest technology is scarce. This study has been conducted to fill this gap and show the implications of the findings for future post-harvest research. The developed search strategy retrieved 2201 studies. However, after excluding duplicates, title, abstract and full article screening, a total of 41 documents were identified. The major findings are: (i) there is an outstanding deficiency of systematic evidence of the effect of climate change, off-farm income and sources of post-harvest information on the adoption of improved post-harvest technologies; (ii) there is very limited information on adoption constraints pertaining to matters of policy, rules and regulations; (iii) there is very thin literature on behavioral constraints associated with limited adoption of improved post-harvest technologies; (iv) most of the studies focused on post-harvest storage technologies (47%) followed by overall post-harvest management practices (25%), processing technologies (19%) and packaging technologies (3%). Much of the information was found on Cereals (58%), especially maize (44%); (v) geographically, Sub-Saharan Africa accounted for 79% of the reviewed interventions, while South Asia occupied only 21%. The findings of this review are intended to guide various post-harvest technologists and decision-makers in addressing the challenge of huge post-harvest losses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constraints" title="constraints">constraints</a>, <a href="https://publications.waset.org/abstracts/search?q=post-harvest%20loss" title=" post-harvest loss"> post-harvest loss</a>, <a href="https://publications.waset.org/abstracts/search?q=post-harvest%20technology" title=" post-harvest technology "> post-harvest technology </a>, <a href="https://publications.waset.org/abstracts/search?q=smallholder%20farmer" title=" smallholder farmer"> smallholder farmer</a> </p> <a href="https://publications.waset.org/abstracts/138228/major-constraints-to-adoption-of-improved-post-harvest-technologies-among-smallholder-farmers-in-developing-countries-a-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138228.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">235</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">30</span> In Exploring Local Community Empowerment and Participation in Blue Tourism Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philasande%20Runeli">Philasande Runeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Lynn%20Jonas"> Lynn Jonas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Empowerment suggests participation is working collaboratively towards shared objectives, obtaining resources and critically analysing one’s social and political differences are all necessary steps in the empowering process. The aim of leadership empowerment is to give a team the resources and encouragement they need to work more productively together. This study explores potential ways to increase local empowerment and participation in blue tourism activities in an urban coastal context in South Africa. Blue tourism, which refers to the application of sustainability practices to tourism activities in coastal and marine settings, has the potential to significantly improve socioeconomic conditions in coastal communities. However, people's engagement in these activities remain restricted. The study uses a constructivist research paradigm and employs a qualitative method, conducting semi-structured interviews with community members from three different communities gaining in-depth perspectives from them. The study's goal is to identify impediments and potential for community participation in blue tourism, as well as offering practical solutions for promoting long-term and inclusive participation. Initial key findings highlight critical barriers to participation, emphasising the importance of skills development, policy alignment with local needs, and public-private partnerships as key components of community empowerment. This study offers policymakers and stakeholders recommendations for promoting inclusive blue tourism initiatives. The recommended initiatives emphasise the significance of skills development, infrastructure investment, and sustainable tourism models in ensuring economic empowerment and environmental conservation in urban coastal communities in developing states. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blue%20tourism" title="blue tourism">blue tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20empowerment%20and%20participation" title=" community empowerment and participation"> community empowerment and participation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20tourism%20models" title=" sustainable tourism models"> sustainable tourism models</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusive%20participation" title=" inclusive participation"> inclusive participation</a> </p> <a href="https://publications.waset.org/abstracts/192162/in-exploring-local-community-empowerment-and-participation-in-blue-tourism-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192162.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">20</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">29</span> TessPy – Spatial Tessellation Made Easy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Hamann">Jonas Hamann</a>, <a href="https://publications.waset.org/abstracts/search?q=Siavash%20Saki"> Siavash Saki</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Hagen"> Tobias Hagen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Discretization of urban areas is a crucial aspect in many spatial analyses. The process of discretization of space into subspaces without overlaps and gaps is called tessellation. It helps understanding spatial space and provides a framework for analyzing geospatial data. Tessellation methods can be divided into two groups: regular tessellations and irregular tessellations. While regular tessellation methods, like squares-grids or hexagons-grids, are suitable for addressing pure geometry problems, they cannot take the unique characteristics of different subareas into account. However, irregular tessellation methods allow the border between the subareas to be defined more realistically based on urban features like a road network or Points of Interest (POI). Even though Python is one of the most used programming languages when it comes to spatial analysis, there is currently no library that combines different tessellation methods to enable users and researchers to compare different techniques. To close this gap, we are proposing TessPy, an open-source Python package, which combines all above-mentioned tessellation methods and makes them easily accessible to everyone. The core functions of TessPy represent the five different tessellation methods: squares, hexagons, adaptive squares, Voronoi polygons, and city blocks. By using regular methods, users can set the resolution of the tessellation which defines the finesse of the discretization and the desired number of tiles. Irregular tessellation methods allow users to define which spatial data to consider (e.g., amenity, building, office) and how fine the tessellation should be. The spatial data used is open-source and provided by OpenStreetMap. This data can be easily extracted and used for further analyses. Besides the methodology of the different techniques, the state-of-the-art, including examples and future work, will be discussed. All dependencies can be installed using conda or pip; however, the former is more recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geospatial%20data%20science" title="geospatial data science">geospatial data science</a>, <a href="https://publications.waset.org/abstracts/search?q=geospatial%20data%20analysis" title=" geospatial data analysis"> geospatial data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=tessellations" title=" tessellations"> tessellations</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20studies" title=" urban studies"> urban studies</a> </p> <a href="https://publications.waset.org/abstracts/148351/tesspy-spatial-tessellation-made-easy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148351.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">128</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> Greenhouse Controlled with Graphical Plotting in Matlab</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bruno%20R.%20A.%20Oliveira">Bruno R.

That way it is possible to connect the stove with a computer and monitor parameters. In the control, it was performed using a PIC 16F877A microprocessor which enabled convert analog signals to digital, perform serial communication with the IC MAX232 and enable signal transistors. The language used in the PIC's management is Basic. There are also a cooling system realized by two coolers 12V distributed in lateral structure, being used for venting and the other for exhaust air. To find out existing temperature inside is used LM35DZ sensor. Other mechanism used in the greenhouse construction was comprised of a reed switch and a magnet; their function is in recognition of the door position where a signal is sent to a buzzer when the door is open. Beyond it exist LEDs that help to identify the operation which the stove is located. To facilitate human-machine communication is employed an LCD display that tells real-time temperature and other information. The average range of design operating without any major problems, taking into account the limitations of the construction material and structure of electrical current conduction, is approximately 65 to 70 ° C. The project is efficient in these conditions, that is, when you wish to get information from a given material to be tested at temperatures not as high. With the implementation of the greenhouse automation, facilitating the temperature control and the development of a structure that encourages correct environment for the most diverse applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=greenhouse" title="greenhouse">greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=microcontroller" title=" microcontroller"> microcontroller</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB" title=" MATLAB"> MATLAB</a> </p> <a href="https://publications.waset.org/abstracts/21288/greenhouse-controlled-with-graphical-plotting-in-matlab" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21288.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">402</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> Determination of Phenolic Compounds in Apples Grown in Different Geographical Regions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mindaugas%20Liaudanskas">Mindaugas Liaudanskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Tallat-Kelpsaite"> Monika Tallat-Kelpsaite</a>, <a href="https://publications.waset.org/abstracts/search?q=Darius%20Kviklys"> Darius Kviklys</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Viskelis"> Jonas Viskelis</a>, <a href="https://publications.waset.org/abstracts/search?q=Pranas%20Viskelis"> Pranas Viskelis</a>, <a href="https://publications.waset.org/abstracts/search?q=Norbertas%20Uselis"> Norbertas Uselis</a>, <a href="https://publications.waset.org/abstracts/search?q=Juozas%20Lanauskas"> Juozas Lanauskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Valdimaras%20Janulis"> Valdimaras Janulis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Apples are an important source of various biologically active compounds used for human health. Phenolic compounds detected in apples are natural antioxidants and have antimicrobial, anti-inflammatory, anticarcinogenic, and cardiovascular protective activity. The quantitative composition of phenolic compounds in apples may be affected by various factors. It is important to investigate it in order to provide the consumer with high-quality well-known composition apples and products made out of it. The objective of this study was to evaluate phenolic compounds quantitative composition in apple fruits grown in a different geographical region. In this study, biological replicates of apple cv. 'Ligol', grown in Lithuania, Latvia, Poland, and Estonia, were investigated. Three biological replicates were analyzed; one of each contained 10 apples. Samples of lyophilized apple fruits were extracted with 70% ethanol (v/v) for 20 min at 40∘C temperature using the ultrasonic bath. The ethanol extracts of apple fruits were analyzed by the high-performance liquid chromatography method. The study found that the geographical location of apple-trees had an impact on the composition of phenolic compounds in apples. The number of quercetin glycosides varied from 314.78±9.47 µg/g (Poland) to 648.17±5.61 µg/g (Estonia). The same trend was also observed with flavan-3-ols (from 829.56±47.17 µg/g to 2300.85±35.49 µg/g), phloridzin (from 55.29±1.7 µg/g to 208.78±0.35 µg/g), and chlorogenic acid (from 501.39±28.84 µg/g to 1704.35±22.65 µg/g). It was observed that the amount of investigated phenolic compounds tended to increase from apples grown in the southern location (Poland) (1701.02±75.38 µg/g) to apples grown northern location (Estonia) (4862.15±56.37 µg/g). Apples (cv. 'Ligol') grown in Estonia accumulated approx. 2.86 times higher amount of phenolic compounds than apples grown in Poland.

The technical systems used to master these demanding tasks are constantly increasing in their degree of automation. It becomes therefore difficult for technical operators to maintain the control over the technical systems and the processes of their job. In particular, the operators must have the necessary experience and knowledge in dealing with a malfunction situation or unexpected event. For this reason, it is of growing importance that the skills relevant for the execution of the job are maintained and further developed beyond the basic training they receive, where they are educated in respect of technical knowledge and the work with guidelines. Training methods aimed at improving the cognitive skills needed by technical operators are still missing and must be developed. Goals of the present study were to identify which are the relevant cognitive skills of technical operators in the railway domain and to define which topics should be addressed by the training of these skills. Observational interviews were conducted in order to identify the main tasks and the organization of the work of technical operators as well as the technical systems used for the execution of their job. Based on this analysis, the most demanding tasks of technical operators could be identified and described. The cognitive skills involved in the execution of these tasks are those, which need to be trained. In order to identify and analyze these cognitive skills a cognitive task analysis (CTA) was developed. CTA specifically aims at identifying the cognitive skills that employees implement when performing their own tasks. The identified cognitive skills of technical operators were summarized and grouped in training topics. For every training topic, specific goals were defined. The goals regard the three main categories; knowledge, skills and attitude to be trained in every training topic. Based on the results of this study, it is possible to develop specific training methods to train the relevant cognitive skills of the technical operators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20skills" title="cognitive skills">cognitive skills</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20task%20analysis" title=" cognitive task analysis"> cognitive task analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20operators%20in%20the%20railway%20domain" title=" technical operators in the railway domain"> technical operators in the railway domain</a>, <a href="https://publications.waset.org/abstracts/search?q=training%20topics" title=" training topics"> training topics</a> </p> <a href="https://publications.waset.org/abstracts/111012/identification-of-training-topics-for-the-improvement-of-the-relevant-cognitive-skills-of-technical-operators-in-the-railway-domain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111012.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">154</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> Tribological Aspects of Advanced Roll Material in Cold Rolling of Stainless Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Tahir">Mohammed Tahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Lagergren"> Jonas Lagergren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vancron 40, a nitrided powder metallurgical tool Steel, is used in cold work applications where the predominant failure mechanisms are adhesive wear or galling. Typical applications of Vancron 40 are among others fine blanking, cold extrusion, deep drawing and cold work rolls for cluster mills. Vancron 40 positive results for cold work rolls for cluster mills and as a tool for some severe metal forming process makes it competitive compared to other type of work rolls that require higher precision, among others in cold rolling of thin stainless steel, which required high surface finish quality. In this project, three roll materials for cold rolling of stainless steel strip was examined, Vancron 40, Narva 12B (a high-carbon, high-chromium tool steel alloyed with tungsten) and Supra 3 (a Chromium-molybdenum tungsten-vanadium alloyed high speed steel). The purpose of this project was to study the depth profiles of the ironed stainless steel strips, emergence of galling and to study the lubrication performance used by steel industries. Laboratory experiments were conducted to examine scratch of the strip, galling and surface roughness of the roll materials under severe tribological conditions. The critical sliding length for onset of galling was estimated for stainless steel with four different lubricants. Laboratory experiments result of performance evaluation of resistance capability of rolls toward adhesive wear under severe conditions for low and high reductions. Vancron 40 in combination with cold rolling lubricant gave good surface quality, prevents galling of metal surfaces and good bearing capacity. <p class="card-text"><strong>Keywords:</strong> <a
