Cesium-137 has long-term radiological effects representing a major concern for the human health. Several physico-chemical methods have been proposed for ¹³⁷Cs removal from impacted water: ion-exchange, adsorption, chemical precipitation, membrane process, coagulation, and electrochemical. However, these methods can be limited by ionic selectivity and efficiency, or they present very restricted full-scale application due to equipment and chemical high costs. On the other hand, adsorption is considered a more cost-effective solution, and activated carbons (ACs) are known as a low-cost and effective adsorbent for a wide range of pollutants among which radionuclides. However, adsorption of Cs onto ACs has been investigated in very few and not exhaustive studies. In addition, exhausted activated carbons are generally discarded in landfill, that is not an eco-friendly and economic solution. Consequently, the regeneration of exhausted ACs must be considered a preferable choice. Several alternatives, including conventional thermal-, solvent-, biological- and electrochemical-regeneration, are available but are affected by several economic or environmental concerns. Microwave (MW) irradiation has been widely used in industrial and environmental applications and it has attracted many attentions to regenerating activated carbons. The growing interest in MW irradiation is based on the passive ability of the irradiated medium to convert a low power irradiation energy into a rapid and large temperature increase if the media presents good dielectric features. ACs are excellent MW-absorbers, with a high mechanical strength and a good resistance towards heating process. This work investigates the feasibility of MW irradiation for the regeneration of Cs-exhausted ACs. Adsorption batch experiments were carried out using commercially available granular activated carbon (GAC), then Cs-saturated AC samples were treated using a controllable bench-scale 2.45-GHz MW oven and investigating different adsorption-regeneration cycles. The regeneration efficiency (RE), weight loss percentage, and textural properties of the AC samples during the adsorption-regeneration cycles were also assessed. Main results demonstrated a relatively low adsorption capacity for Cs, although the feasibility of ACs was strictly linked to their dielectric nature, which allows a very efficient thermal regeneration by MW irradiation. The weight loss percentage was found less than 2%, and an increase in RE after three cycles was also observed. Furthermore, MW regeneration preserved the pore structure of the regenerated ACs. For a deeper exploration of the full-scale applicability of MW regeneration, further investigations on more adsorption-regeneration cycles or using fixed-bed columns are required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption%20mechanisms" title="adsorption mechanisms">adsorption mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=cesium" title=" cesium"> cesium</a>, <a href="https://publications.waset.org/abstracts/search?q=granular%20activated%20carbons" title=" granular activated carbons"> granular activated carbons</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20regeneration" title=" microwave regeneration"> microwave regeneration</a> </p> <a href="https://publications.waset.org/abstracts/120241/regeneration-of-cesium-exhausted-activated-carbons-by-microwave-irradiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120241.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">141</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> An Approach to Physical Performance Analysis for Judo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Frassinelli">Stefano Frassinelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Niccolai"> Alessandro Niccolai</a>, <a href="https://publications.waset.org/abstracts/search?q=Riccardo%20E.%20Zich"> Riccardo E.

Many techniques have been developed to measure and analyse efficiently the performance of athletes in some sports, but in combat sports these techniques found in many times their limits, due to the high interaction between the two opponents during the competition. In this paper the problem will be framed. Moreover the physical performance measurement problem will be analysed and three different techniques to manage it will be presented.

An important part of the HMI system is the ability to monitor the level of situational awareness (SA) of any driver in real-time, in different scenarios, and without any pre-calibration. Presenting state-of-the-art machine learning models used to measure SA is the purpose of this systematic review. Investigating the limitations of each type of sensor, the gaps, and the most suited sensor and computational model that can be used in driving applications. To the author’s best knowledge this is the first literature review identifying online and offline classification methods used to measure SA, explaining which measurements are subject or session-specific, and how many classifications can be done with each classification model. This information can be very useful for researchers measuring SA to identify the most suited model to measure SA for different applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=situational%20awareness" title="situational awareness">situational awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20driving" title=" autonomous driving"> autonomous driving</a>, <a href="https://publications.waset.org/abstracts/search?q=gaze%20metrics" title=" gaze metrics"> gaze metrics</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=ECG" title=" ECG"> ECG</a> </p> <a href="https://publications.waset.org/abstracts/157210/a-systematic-review-of-situational-awareness-and-cognitive-load-measurement-in-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157210.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">119</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> The Buccal Fat Pad for Closure of Oroantral Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefano%20A.%20Denes">Stefano A.

In this paper, the vibrations of the springboard will be analyzed by means of typical tools for vibration analysis: Firstly, a modal analysis will be done on two different models of the springboard, then, these two model and another one will be analyzed with a time analysis, done integrating the equations of motion od deformable bodies. All these analyses will be compared with experimental data measured on a real springboard by means of a 6-axis accelerometer; these measurements are aimed to assess the models proposed.

Understanding the relationship between dissolved oxygen (DO) and water temperature is crucial, as these variables directly impact the health, behavior, and survival of fish populations. This study investigated how DO levels, water temperature, and atmospheric temperature interact in Sampaloc Lake to assess the risk of fish mortality. By employing a combination of linear regression models and machine learning techniques, researchers developed predictive models to forecast DO concentrations at various depths. The results indicate that while DO levels generally decrease with depth, the predicted concentrations are sufficient to support the survival of common fish species in Sampaloc Lake during March, April, and May 2025. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquaculture" title="aquaculture">aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolved%20oxygen" title=" dissolved oxygen"> dissolved oxygen</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20temperature" title=" water temperature"> water temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20analysis" title=" regression analysis"> regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20mass%20mortality" title=" fish mass mortality"> fish mass mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20warning%20system" title=" early warning system"> early warning system</a> </p> <a href="https://publications.waset.org/abstracts/189671/analysis-of-photic-zones-summer-period-dissolved-oxygen-and-temperature-as-an-early-warning-system-of-fish-mass-mortality-in-sampaloc-lake-in-san-pablo-laguna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189671.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">35</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> The Use of the Flat Field Panel for the On-Ground Calibration of Metis Coronagraph on Board of Solar Orbiter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Casini">C.

The payload is composed of 10 instruments, among which there is the Metis coronagraph. A coronagraph aims at taking images of the solar corona: the occulter element simulates a total solar eclipse. This work presents some of the results obtained in the visible light band (580-640 nm) using a flat field panel source. The flat field panel gives a uniform illumination; consequently, it has been used during the on-ground calibration for several purposes: evaluating the response of each pixel of the detector (linearity); and characterizing the Field of View of the coronagraph. As a conclusion, a major result is the verification that the requirement for the Field of View (FoV) of Metis is fulfilled. Some investigations are in progress in order to verify that the performance measured on-ground did not change after launch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20orbiter" title="solar orbiter">solar orbiter</a>, <a href="https://publications.waset.org/abstracts/search?q=Metis" title=" Metis"> Metis</a>, <a href="https://publications.waset.org/abstracts/search?q=coronagraph" title=" coronagraph"> coronagraph</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20field%20panel" title=" flat field panel"> flat field panel</a>, <a href="https://publications.waset.org/abstracts/search?q=calibration" title=" calibration"> calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=on-ground" title=" on-ground"> on-ground</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a> </p> <a href="https://publications.waset.org/abstracts/131441/the-use-of-the-flat-field-panel-for-the-on-ground-calibration-of-metis-coronagraph-on-board-of-solar-orbiter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131441.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">106</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> Building Information Modelling Implementation in the Lifecycle of Sustainable Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Scarlet%20Alejandra%20Romano">Scarlet Alejandra Romano</a>, <a href="https://publications.waset.org/abstracts/search?q=Joni%20Kareco"> Joni Kareco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The three pillars of sustainability (social, economic and environmental) are relevant concepts to the Architecture, Engineering, and Construction (AEC) industry because of the increase of international agreements and guidelines related to this topic during the last years. Considering these three pillars, the AEC industry faces important challenges, for instance, to decrease the carbon emissions (environmental challenge), design sustainable spaces for people (social challenge), and improve the technology of this field to reduce costs and environmental problems (economic and environmental challenge). One alternative to overcome these challenges is Building Information Modelling program (BIM) because according to several authors, this technology improves the performance of the sustainable buildings in all their lifecycle phases. The main objective of this paper is to explore and analyse the current advantages and disadvantages of the BIM implementation in the life-cycle of sustainable buildings considering the three pillars of sustainability as analysis parameters. The methodology established to achieve this objective is exploratory-descriptive with the literature review technique. The partial results illustrate that despite the BIM disadvantages and the lack of information about its social sustainability advantages, this software represents a significant opportunity to improve the three sustainable pillars of the sustainable buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modelling" title="building information modelling">building information modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20lifecycle%20analysis" title=" building lifecycle analysis"> building lifecycle analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20buildings" title=" sustainable buildings"> sustainable buildings</a> </p> <a href="https://publications.waset.org/abstracts/89629/building-information-modelling-implementation-in-the-lifecycle-of-sustainable-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89629.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">186</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> Factors Affecting Cost Efficiency of Municipal Waste Services in Tuscan Municipalities: An Empirical Investigation by Accounting for Different Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Molinos-Senante">María Molinos-Senante</a>, <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Romano"> Giulia Romano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims at investigating the effect of ownership in the efficiency assessment of municipal solid waste management. In doing so, the Data Envelopment Analysis meta-frontier approach integrating unsorted waste as undesirable output was applied. Three different clusters of municipalities have been created on the basis of the ownership type of municipal waste operators. In the second stage of analysis, the paper investigates factors affecting efficiency, in order to provide an outlook of levers to be used by policy and decision makers to improve efficiency, taking into account different management models in force. Results show that public waste management firms have better performance than mixed and private ones since their efficiency scores are significantly larger. Moreover, it has been demonstrated that the efficiency of waste management firms is statistically influenced by the age of population, population served, municipal size, population density and tourism rate. It evidences the importance of economies of scale on the cost efficiency of waste management. This issue is relevant for policymakers to define and implement policies aimed to improve the long-term sustainability of waste management in municipalities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20envelopment%20analysis" title="data envelopment analysis">data envelopment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=municipal%20solid%20waste" title=" municipal solid waste"> municipal solid waste</a>, <a href="https://publications.waset.org/abstracts/search?q=ownership" title=" ownership"> ownership</a>, <a href="https://publications.waset.org/abstracts/search?q=undesirable%20output" title=" undesirable output"> undesirable output</a> </p> <a href="https://publications.waset.org/abstracts/107760/factors-affecting-cost-efficiency-of-municipal-waste-services-in-tuscan-municipalities-an-empirical-investigation-by-accounting-for-different-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107760.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">159</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 Project in the Framework “Nextgenerationeu”: Sustainable Photoelectrochemical Hydrogen Evolution - SERGIO</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patrizia%20Frontera">Patrizia Frontera</a>, <a href="https://publications.waset.org/abstracts/search?q=Anastasia%20Macario"> Anastasia Macario</a>, <a href="https://publications.waset.org/abstracts/search?q=Simona%20Crispi"> Simona Crispi</a>, <a href="https://publications.waset.org/abstracts/search?q=Angela%20Malara"> Angela Malara</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierantonio%20De%20Luca"> Pierantonio De Luca</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Trocino"> Stefano Trocino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The exploration of solar energy for the photoelectrochemical splitting of water into hydrogen and oxygen has been extensively researched as a means of generating sustainable H₂ fuel. However, despite these efforts, commercialization of this technology has not yet materialized. Presently, the primary impediments to commercialization include low solar-to-hydrogen efficiency (2-3% in PEC with an active area of up to 10-15 cm²), the utilization of costly and critical raw materials (e.g., BiVO₄), and energy losses during the separation of H₂ from O₂ and H₂O vapours in the output stream. The SERGIO partners have identified an advanced approach to fabricate photoelectrode materials, coupled with an appropriate scientific direction to achieve cost-effective solar-driven H₂ production in a tandem photoelectrochemical cell. This project is designed to reach Technology Readiness Level (TRL) 4 by validating the technology in the laboratory using a cell with an active area of up to 10 cm², boasting a solar-to-hydrogen efficiency of 5%, and ensuring acceptable hydrogen purity (99.99%). Our objectives include breakthroughs in cost efficiency, conversion efficiency, and H₂ purity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photoelectrolysis" title="photoelectrolysis">photoelectrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20hydrogen" title=" green hydrogen"> green hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=photoelectrochemical%20cell" title=" photoelectrochemical cell"> photoelectrochemical cell</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductors" title=" semiconductors"> semiconductors</a> </p> <a href="https://publications.waset.org/abstracts/183030/a-project-in-the-framework-nextgenerationeu-sustainable-photoelectrochemical-hydrogen-evolution-sergio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183030.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">39</span> Machine Learning Methods for Flood Hazard Mapping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Zappacosta">Stefano Zappacosta</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristiano%20Bove"> Cristiano Bove</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Carmela%20Marinelli"> Maria Carmela Marinelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20di%20Lauro"> Paola di Lauro</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarina%20Spasenovic"> Katarina Spasenovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorenzo%20Ostano"> Lorenzo Ostano</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Aiello"> Giuseppe Aiello</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Pietrosanto"> Marco Pietrosanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a novel neural network approach for assessing flood hazard mapping. The core of the model is a machine learning component fed by frequency ratios, namely statistical correlations between flood event occurrences and a selected number of topographic properties. The proposed hybrid model can be used to classify four different increasing levels of hazard. The classification capability was compared with the flood hazard mapping River Basin Plans (PAI) designed by the Italian Institute for Environmental Research and Defence, ISPRA (Istituto Superiore per la Protezione e la Ricerca Ambientale). The study area of Piemonte, an Italian region, has been considered without loss of generality. The frequency ratios may be used as a standalone block to model the flood hazard mapping. Nevertheless, the mixture with a neural network improves the classification power of several percentage points, and may be proposed as a basic tool to model the flood hazard map in a wider scope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flood%20modeling" title="flood modeling">flood modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard%20map" title=" hazard map"> hazard map</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogeological%20risk" title=" hydrogeological risk"> hydrogeological risk</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20risk%20assessment" title=" flood risk assessment"> flood risk assessment</a> </p> <a href="https://publications.waset.org/abstracts/140468/machine-learning-methods-for-flood-hazard-mapping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140468.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">177</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> Fuzzy Inference System for Risk Assessment Evaluation of Wheat Flour Product Manufacturing Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atrin%20Barzegar">Atrin Barzegar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yas%20Barzegar"> Yas Barzegar</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Marrone"> Stefano Marrone</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Bellini"> Francesco Bellini</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Verde"> Laura Verde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research is to develop an intelligent system to analyze the risk level of wheat flour product manufacturing system.

The output of each one of the Physical, Chemical, Biological and Environmental Failures will be the input of the final manufacturing systems. The proposed model based on Mamdani Fuzzy Inference Systems gives a performance ranking of wheat flour products manufacturing systems. The first step is obtaining data to identify the failure modes from expert’s opinions.

We study diversification benefits of Sukuk, their correlation with other asset classes and the effects of their inclusion in investment portfolios of institutional and retail investors, through a comprehensive comparison of their risk/return profiles during and after the financial crisis. We find a beneficial performance adjusted for the specific volatility together with a lower correlation especially during the financial crisis. The distribution of Sukuk returns is positively skewed and leptokurtic, with a risk/return profile similarly to high yield bonds. Overall, our results suggest that Sukuk present diversification opportunities, a significant volatility-adjusted performance and lower correlations especially during the financial crisis. Our findings are relevant for a number of institutional investors. Long term investors, such as life insurers would benefit from Sukuk’s protective features during financial crisis yet keeping return and growth opportunities, whereas banks would gain due to their role of placers, advisors, market makers or underwriters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sukuk" title="sukuk">sukuk</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20beta%20asset" title=" zero beta asset"> zero beta asset</a>, <a href="https://publications.waset.org/abstracts/search?q=asset%20allocation" title=" asset allocation"> asset allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=sukuk%20market" title=" sukuk market"> sukuk market</a> </p> <a href="https://publications.waset.org/abstracts/21247/in-search-of-zero-beta-assets-evidence-from-the-sukuk-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21247.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">477</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> Improvement of Sleep Quality Through Manual and Non-Pharmacological Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Aceranti">Andreas Aceranti</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Roman%C3%B2"> Sergio Romanò</a>, <a href="https://publications.waset.org/abstracts/search?q=Simonetta%20Vernocchi"> Simonetta Vernocchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Arnaboldi"> Silvia Arnaboldi</a>, <a href="https://publications.waset.org/abstracts/search?q=Emilio%20Mazza"> Emilio Mazza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a result of the Sars-Cov2 pandemic, the incidence of thymism disorders has significantly increased and, often, patients are reluctant to want to take drugs aimed at stabilizing mood. In order to provide an alternative approach to drug therapies, we have prepared a study in order to evaluate the possibility of improving the quality of life of these subjects through osteopathic treatment. Patients were divided into visceral and fascial manual treatment with the aim of increasing serotonin levels and stimulating the vagus nerve through validated techniques. The results were evaluated through the administration of targeted questionnaires in order to assess quality of life, mood, sleep and intestinal functioning. At a first endpoint we found, in patients undergoing fascial treatment, an increase in quality of life and sleep: in fact, they report a decrease in the number of nocturnal awakenings; a reduction in falling asleep times and greater rest upon waking. In contrast, patients undergoing visceral treatment, as well as those included in the control group, did not show significant improvements. Patients in the fascial group have, in fact, reported an improvement in thymism and subjective quality of life with a generalized improvement in function. Although the study is still ongoing, based on the results of the first endpoint we can hypothesize that fascial stimulation of the vagus nerve with manual and osteopathic techniques may be a valid alternative to pharmacological treatments in mood and sleep disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ostheopathy" title="ostheopathy">ostheopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=insomnia" title=" insomnia"> insomnia</a>, <a href="https://publications.waset.org/abstracts/search?q=noctural%20awakening" title=" noctural awakening"> noctural awakening</a>, <a href="https://publications.waset.org/abstracts/search?q=thymism" title=" thymism"> thymism</a> </p> <a href="https://publications.waset.org/abstracts/160281/improvement-of-sleep-quality-through-manual-and-non-pharmacological-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160281.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">35</span> Advanced Seismic Retrofit of a School Building by a DFP Base Isolation Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Sorace">Stefano Sorace</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20Terenzi"> Gloria Terenzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of a base isolation seismic retrofit solution for a reinforced concrete school building is presented in this paper. The building was assumed as a benchmark structure for a Research Project financed by the Italian Department of Civil Protection, and is representative of several similar public edifices designed with earlier Technical Standards editions, in Italy as well as in other earthquake-prone European countries. The structural characteristics of the building, and a synthesis of the investigation campaigns developed on it, are initially presented. The mechanical parameters, dimensions, locations and installation details of the base isolation system, incorporating double friction pendulum sliding bearings as protective devices, are then illustrated, along with the performance assessment analyses carried out in original and rehabilitated conditions according to a full non-linear dynamic approach. The results of the analyses show a remarkable enhancement of the seismic response capacities of the structure in base-isolated configuration. This allows reaching the high performance levels postulated in the rehabilitation design with notably lower costs and architectural intrusion as compared to traditional retrofit interventions designed for the same objectives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20retrofit" title="seismic retrofit">seismic retrofit</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20assessment" title=" seismic assessment"> seismic assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=r%2Fc%20structures" title=" r/c structures"> r/c structures</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20buildings" title=" school buildings"> school buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20isolation" title=" base isolation"> base isolation</a> </p> <a href="https://publications.waset.org/abstracts/9559/advanced-seismic-retrofit-of-a-school-building-by-a-dfp-base-isolation-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9559.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">270</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> Utilizing Extended Reality in Disaster Risk Reduction Education: A Scoping Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Scippo">Stefano Scippo</a>, <a href="https://publications.waset.org/abstracts/search?q=Damiana%20Luzzi"> Damiana Luzzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Cuomo"> Stefano Cuomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Ranieri"> Maria Ranieri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In response to the rise in natural disasters linked to climate change, numerous studies on Disaster Risk Reduction Education (DRRE) have emerged since the '90s, mainly using a didactic transmission-based approach. Effective DRRE should align with an interactive, experiential, and participatory educational model, which can be costly and risky. A potential solution is using simulations facilitated by eXtended Reality (XR). Research Question: This study aims to conduct a scoping review to explore educational methodologies that use XR to enhance knowledge among teachers, students, and citizens about environmental risks, natural disasters (including climate-related ones), and their management. Method: A search string of 66 keywords was formulated, spanning three domains: 1) education and target audience, 2) environment and natural hazards, and 3) technologies. On June 21st, 2023, the search string was used across five databases: EBSCOhost, IEEE Xplore, PubMed, Scopus, and Web of Science. After deduplication and removing papers without abstracts, 2,152 abstracts (published between 2013 and 2023) were analyzed and 2,062 papers were excluded, followed by the exclusion of 56 papers after full-text scrutiny. Excluded studies focused on unrelated technologies, non-environmental risks, and lacked educational outcomes or accessible texts. Main Results: The 34 reviewed papers were analyzed for context, risk type, research methodology, learning objectives, XR technology use, outcomes, and educational affordances of XR. Notably, since 2016, there has been a rise in scientific publications, focusing mainly on seismic events (12 studies) and floods (9), with a significant contribution from Asia (18 publications), particularly Japan (7 studies). Methodologically, the studies were categorized into empirical (26) and non-empirical (8). Empirical studies involved user or expert validation of XR tools, while non-empirical studies included systematic reviews and theoretical proposals without experimental validation. Empirical studies were further classified into quantitative, qualitative, or mixed-method approaches. Six qualitative studies involved small groups of users or experts, while 20 quantitative or mixed-method studies used seven different research designs, with most (17) employing a quasi-experimental, one-group post-test design, focusing on XR technology usability over educational effectiveness. Non-experimental studies had methodological limitations, making their results hypothetical and in need of further empirical validation. Educationally, the learning objectives centered on knowledge and skills for surviving natural disaster emergencies. All studies recommended XR technologies for simulations or serious games but did not develop comprehensive educational frameworks around these tools. XR-based tools showed potential superiority over traditional methods in teaching risk and emergency management skills. However, conclusions were more valid in studies with experimental designs; otherwise, they remained hypothetical without empirical evidence. The educational affordances of XR, mainly user engagement, were confirmed by the studies. Authors’ Conclusions: The analyzed literature lacks specific educational frameworks for XR in DRRE, focusing mainly on survival knowledge and skills. There is a need to expand educational approaches to include uncertainty education, developing competencies that encompass knowledge, skills, and attitudes like risk perception. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disaster%20risk%20reduction%20education" title="disaster risk reduction education">disaster risk reduction education</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20technologies" title=" educational technologies"> educational technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=scoping%20review" title=" scoping review"> scoping review</a>, <a href="https://publications.waset.org/abstracts/search?q=XR%20technologies" title=" XR technologies"> XR technologies</a> </p> <a href="https://publications.waset.org/abstracts/188340/utilizing-extended-reality-in-disaster-risk-reduction-education-a-scoping-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188340.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">24</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> Direct Visualization of Shear Induced Structures in Wormlike Micellar Solutions by Microfluidics and Advanced Microscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carla%20Caiazza">Carla Caiazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Preziosi"> Valentina Preziosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Tomaiuolo"> Giovanna Tomaiuolo</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20O%27Sullivan"> Denis O'Sullivan</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincenzo%20Guida"> Vincenzo Guida</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Guido"> Stefano Guido</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last decades, wormlike micellar solutions have been extensively used to tune the rheological behavior of home care and personal care products. This and other successful applications underlie the growing attention that both basic and applied research are devoting to these systems, and to their unique rheological and flow properties. One of the key research topics is the occurrence of flow instabilities at high shear rates (such as shear banding), with the possibility of appearance of flow induced structures. In this scenario, microfluidics is a powerful tool to get a deeper insight into the flow behavior of a wormlike micellar solution, as the high confinement of a microfluidic device facilitates the onset of the flow instabilities; furthermore, thanks to its small dimensions, it can be coupled with optical microscopy, allowing a direct visualization of flow structuring phenomena. Here, the flow of a widely used wormlike micellar solution through a glass capillary has been studied, by coupling the microfluidic device with μPIV techniques. The direct visualization of flow-induced structures and the flow visualization analysis highlight a relationship between solution structuring and the onset of discontinuities in the velocity profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20instabilities" title="flow instabilities">flow instabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=flow-induced%20structures" title=" flow-induced structures"> flow-induced structures</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%BCPIV" title=" μPIV"> μPIV</a>, <a href="https://publications.waset.org/abstracts/search?q=wormlike%20micelles" title=" wormlike micelles "> wormlike micelles </a> </p> <a href="https://publications.waset.org/abstracts/68641/direct-visualization-of-shear-induced-structures-in-wormlike-micellar-solutions-by-microfluidics-and-advanced-microscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68641.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">346</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> Oxygenation in Turbulent Flows over Block Ramps</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thendiyath%20Roshni">Thendiyath Roshni</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Pagliara"> Stefano Pagliara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Block ramps (BR) or rock chutes are eco-friendly natural river restoration structures. BR are made of ramp of rocks and flows over BR develop turbulence and helps in the entrainment of ambient air. These act as natural aerators in river flow and therefore leads to oxygenation of water. As many of the hydraulic structures in rivers, hinders the natural path for aquatic habitat. However, flows over BR ascertains a natural rocky flow and ensures safe and natural movement for aquatic habitat. Hence, BR is considered as a better alternative for drop structures. As water quality is concerned, turbulent and aerated flows over BR or macro-roughness conditions improves aeration and thereby oxygenation. Hence, the objective of this paper is to study the oxygenation in the turbulent flows over BR. Experimental data were taken for a slope (S) of 27.5% for three discharges (Q = 9, 15 and 21 lps) conditions. Air concentration were measured with the help of air concentration probe for three different discharges in the uniform flow region. Oxygen concentration is deduced from the air concentration as ambient air is entrained in the flows over BR. Air concentration profiles and oxygen profiles are plotted in the uniform flow region for three discharges and found that air concentration and oxygen concentration does not show any remarkable variation in properties in the longitudinal profile in uniform flow region. An empirical relation is developed for finding the average oxygen concentration (Oₘ) for S = 27.5% in the uniform flow region for 9 < Q < 21 lps. The results show that as the discharge increases over BR, there is a reduction of oxygen concentration in the uniform flow region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeration" title="aeration">aeration</a>, <a href="https://publications.waset.org/abstracts/search?q=block%20ramps" title=" block ramps"> block ramps</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygenation" title=" oxygenation"> oxygenation</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flows" title=" turbulent flows"> turbulent flows</a> </p> <a href="https://publications.waset.org/abstracts/98618/oxygenation-in-turbulent-flows-over-block-ramps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98618.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">174</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> Ab-initio Calculations on the Mechanism of Action of Platinum and Ruthenium Complexes in Phototherapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eslam%20Dabbish">Eslam Dabbish</a>, <a href="https://publications.waset.org/abstracts/search?q=Fortuna%20Ponte"> Fortuna Ponte</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Scoditti"> Stefano Scoditti</a>, <a href="https://publications.waset.org/abstracts/search?q=Emilia%20Sicilia"> Emilia Sicilia</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20Mazzone"> Gloria Mazzone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The medical techniques based on the use of light for activating the drug are occupying a prominent place in the cancer treatment due to their selectivity that contributes to reduce undesirable side effects of conventional chemotherapy. Among these therapeutic treatments, photodynamic therapy (PDT) and photoactivated chemotherapy (PACT) are emerging as complementary approaches for selective destruction of neoplastic tissue through direct cellular damage. Both techniques rely on the employment of a molecule, photosensitizer (PS), able to absorb within the so-called therapeutic window. Thus, the exposure to light of otherwise inert molecules promotes the population of excited states of the drug, that in PDT are able to produce the cytotoxic species, such as 1O2 and other ROS, in PACT can be responsible of the active species release or formation. Following the success of cisplatin in conventional treatments, many other transition metal complexes were explored as anticancer agents for applications in different medical approaches, including PDT and PACT, in order to improve their chemical, biological and photophysical properties. In this field, several crucial characteristics of candidate PSs can be accurately predicted from first principle calculations, especially in the framework of density functional theory and its time-dependent formulation, contributing to the understanding of the entire photochemical pathways involved which can ultimately help in improving the efficiency of a drug. A brief overview of the outcomes on some platinum and ruthenium-based PSs proposed for the application in the two phototherapies will be provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TDDFT" title="TDDFT">TDDFT</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20complexes" title=" metal complexes"> metal complexes</a>, <a href="https://publications.waset.org/abstracts/search?q=PACT" title=" PACT"> PACT</a>, <a href="https://publications.waset.org/abstracts/search?q=PDT" title=" PDT"> PDT</a> </p> <a href="https://publications.waset.org/abstracts/152251/ab-initio-calculations-on-the-mechanism-of-action-of-platinum-and-ruthenium-complexes-in-phototherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152251.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">103</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> Corrosion Mitigation in Gas Facilities Piping Through the Use of FBE Coated Pipes and Corrosion Resistant Alloy Girth Welds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fadi%20Chammas">Fadi Chammas</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Alkhaldi"> Saad Alkhaldi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Alghamdi"> Tariq Alghamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Alexandirs"> Stefano Alexandirs</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The operating conditions and corrosive nature of the process fluid in the Haradh and Hawiyah areas are subjecting facility piping to undesirable corrosion phenomena. Therefore, production headers inside remote headers have been internally cladded with high alloy material to mitigate the corrosion damage mechanism. Corrosion mitigation in the jump-over lines, constructed between the existing flowlines and the newly constructed facilities to provide operational flexibility, is proposed. This corrosion mitigation system includes the application of fusion bond epoxy (FBE) coating on the internal surface of the pipe and depositing corrosion-resistant alloy (CRA) weld layers at pipe and fittings ends to protect the carbon steel material. In addition, high alloy CRA weld material is used to deposit the girth weld between the 90-degree elbows and mating internally coated segments. A rigorous testing and qualification protocol was established prior to actual adoption at the Haradh and Hawiyah Field Gas Compression Program, currently being executed by Saudi Aramco. The proposed mitigation system, aimed at applying the cladding at the ends of the internally FBE coated pipes/elbows, will resolve field joint coating challenges, eliminate the use of approximately (1700) breakout flanges, and prevent the potential hydrocarbon leaks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pipelines" title="pipelines">pipelines</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=cost-saving" title=" cost-saving"> cost-saving</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20completion" title=" project completion"> project completion</a> </p> <a href="https://publications.waset.org/abstracts/149157/corrosion-mitigation-in-gas-facilities-piping-through-the-use-of-fbe-coated-pipes-and-corrosion-resistant-alloy-girth-welds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Joint Training Offer Selection and Course Timetabling Problems: Models and Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gianpaolo%20Ghiani">Gianpaolo Ghiani</a>, <a href="https://publications.waset.org/abstracts/search?q=Emanuela%20Guerriero"> Emanuela Guerriero</a>, <a href="https://publications.waset.org/abstracts/search?q=Emanuele%20Manni"> Emanuele Manni</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Romano"> Alessandro Romano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we deal with a variant of the classical course timetabling problem that has a practical application in many areas of education. In particular, in this paper we are interested in high schools remedial courses. The purpose of such courses is to provide under-prepared students with the skills necessary to succeed in their studies. In particular, a student might be under prepared in an entire course, or only in a part of it. The limited availability of funds, as well as the limited amount of time and teachers at disposal, often requires schools to choose which courses and/or which teaching units to activate. Thus, schools need to model the training offer and the related timetabling, with the goal of ensuring the highest possible teaching quality, by meeting the above-mentioned financial, time and resources constraints. Moreover, there are some prerequisites between the teaching units that must be satisfied. We first present a Mixed-Integer Programming (MIP) model to solve this problem to optimality. However, the presence of many peculiar constraints contributes inevitably in increasing the complexity of the mathematical model. Thus, solving it through a general purpose solver may be performed for small instances only, while solving real-life-sized instances of such model requires specific techniques or heuristic approaches. For this purpose, we also propose a heuristic approach, in which we make use of a fast constructive procedure to obtain a feasible solution. To assess our exact and heuristic approaches we perform extensive computational results on both real-life instances (obtained from a high school in Lecce, Italy) and randomly generated instances. Our tests show that the MIP model is never solved to optimality, with an average optimality gap of 57%. On the other hand, the heuristic algorithm is much faster (in about the 50% of the considered instances it converges in approximately half of the time limit) and in many cases allows achieving an improvement on the objective function value obtained by the MIP model. Such an improvement ranges between 18% and 66%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heuristic" title="heuristic">heuristic</a>, <a href="https://publications.waset.org/abstracts/search?q=MIP%20model" title=" MIP model"> MIP model</a>, <a href="https://publications.waset.org/abstracts/search?q=remedial%20course" title=" remedial course"> remedial course</a>, <a href="https://publications.waset.org/abstracts/search?q=school" title=" school"> school</a>, <a href="https://publications.waset.org/abstracts/search?q=timetabling" title=" timetabling"> timetabling</a> </p> <a href="https://publications.waset.org/abstracts/29805/joint-training-offer-selection-and-course-timetabling-problems-models-and-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29805.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">605</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> A Simple Model for Solar Panel Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefano%20M.%20Spagocci">Stefano M.

RETScreen is interfaced with meteorological databases, so that efficiency calculations can be realistically carried out. The author has recently contributed to the development of solar modules with accumulation capability and an embedded water purifier, aimed at off-grid users such as users in developing countries. The software packages examined do not allow to take ancillary equipment into account, hence the decision to implement a technical and financial model of the system. The author realized that, rather than re-implementing the quite sophisticated model of RETScreen - a mathematical description of which is anyway not publicly available - it was possible to drastically simplify it, including the meteorological factors which, in RETScreen, are presented in a numerical form. The day-by-day efficiency of a photovoltaic solar panel was parametrized by the product of factors expressing, respectively, daytime duration, solar right ascension motion, solar declination motion, cloudiness, temperature. For the sun-motion-dependent factors, positional astronomy formulae, simplified by the author, were employed. Meteorology-dependent factors were fitted by simple trigonometric functions, employing numerical data supplied by RETScreen. The accuracy of our model was tested by comparing it to the predictions of RETScreen; the accuracy obtained was 11%. In conclusion, our study resulted in a model that can be easily implemented in a spreadsheet - thus being easily manageable by non-specialist personnel - or in more sophisticated software packages. The model was used in a number of design exercises, concerning photovoltaic solar panels and ancillary equipment like the above-mentioned water purifier. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clean%20energy" title="clean energy">clean energy</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20engineering" title=" energy engineering"> energy engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modelling" title=" mathematical modelling"> mathematical modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20panels" title=" photovoltaic panels"> photovoltaic panels</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a> </p> <a href="https://publications.waset.org/abstracts/183471/a-simple-model-for-solar-panel-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183471.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">68</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> Monte Carlo and Biophysics Analysis in a Criminal Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luca%20Indovina">Luca Indovina</a>, <a href="https://publications.waset.org/abstracts/search?q=Carmela%20Coppola"> Carmela Coppola</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlo%20Altucci"> Carlo Altucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Riccardo%20Barberi"> Riccardo Barberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rocco%20Romano"> Rocco Romano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper a real court case, held in Italy at the Court of Nola, in which a correct physical description, conducted with both a Monte Carlo and biophysical analysis, would have been sufficient to arrive at conclusions confirmed by documentary evidence, is considered. This will be an example of how forensic physics can be useful in confirming documentary evidence in order to reach hardly questionable conclusions. This was a libel trial in which the defendant, Mr. DS (Defendant for Slander), had falsely accused one of his neighbors, Mr. OP (Offended Person), of having caused him some damages. The damages would have been caused by an external plaster piece that would have detached from the neighbor’s property and would have hit Mr DS while he was in his garden, much more than a meter far away from the facade of the building from which the plaster piece would have detached. In the trial, Mr. DS claimed to have suffered a scratch on his forehead, but he never showed the plaster that had hit him, nor was able to tell from where the plaster would have arrived. Furthermore, Mr. DS presented a medical certificate with a diagnosis of contusion of the cerebral cortex. On the contrary, the images of Mr. OP’s security cameras do not show any movement in the garden of Mr. DS in a long interval of time (about 2 hours) around the time of the alleged accident, nor do they show any people entering or coming out from the house of Mr. DS in the same interval of time. Biophysical analysis shows that both the diagnosis of the medical certificate and the wound declared by the defendant, already in conflict with each other, are not compatible with the fall of external plaster pieces too small to be found. The wind was at a level 1 of the Beaufort scale, that is, unable to raise even dust (level 4 of the Beaufort scale). Therefore, the motion of the plaster pieces can be described as a projectile motion, whereas collisions with the building cornice can be treated using Newtons law of coefficients of restitution. Numerous numerical Monte Carlo simulations show that the pieces of plaster would not have been able to reach even the garden of Mr. DS, let alone a distance over 1.30 meters. Results agree with the documentary evidence (images of Mr. OP’s security cameras) that Mr. DS could not have been hit by plaster pieces coming from Mr. OP’s property. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biophysics%20analysis" title="biophysics analysis">biophysics analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulations" title=" Monte Carlo simulations"> Monte Carlo simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=Newton%E2%80%99s%20law%20of%20restitution" title=" Newton’s law of restitution"> Newton’s law of restitution</a>, <a href="https://publications.waset.org/abstracts/search?q=projectile%20motion" title=" projectile motion"> projectile motion</a> </p> <a href="https://publications.waset.org/abstracts/130139/monte-carlo-and-biophysics-analysis-in-a-criminal-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130139.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">26</span> Incorporation of Growth Factors onto Hydrogels via Peptide Mediated Binding for Development of Vascular Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katie%20Kilgour">Katie Kilgour</a>, <a href="https://publications.waset.org/abstracts/search?q=Brendan%20Turner"> Brendan Turner</a>, <a href="https://publications.waset.org/abstracts/search?q=Carly%20Catella"> Carly Catella</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Daniele"> Michael Daniele</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Menegatti"> Stefano Menegatti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In vivo, the extracellular matrix (ECM) provides biochemical and mechanical properties that are instructional to resident cells to form complex tissues with characteristics to develop and support vascular networks. In vitro, the development of vascular networks can be guided by biochemical patterning of substrates via spatial distribution and display of peptides and growth factors to prompt cell adhesion, differentiation, and proliferation. We have developed a technique utilizing peptide ligands that specifically bind vascular endothelial growth factor (VEGF), erythropoietin (EPO), or angiopoietin-1 (ANG1) to spatiotemporally distribute growth factors to cells. This allows for the controlled release of each growth factor, ultimately enhancing the formation of a vascular network. Our engineered tissue constructs (ETCs) are fabricated out of gelatin methacryloyl (GelMA), which is an ideal substrate for tailored stiffness and bio-functionality, and covalently patterned with growth factor specific peptides. These peptides mimic growth factor receptors, facilitating the non-covalent binding of the growth factors to the ETC, allowing for facile uptake by the cells. We have demonstrated in the absence of cells the binding affinity of VEGF, EPO, and ANG1 to their respective peptides and the ability for each to be patterned onto a GelMA substrate. The ability to organize growth factors on an ETC provides different functionality to develop organized vascular networks. Our results demonstrated a method to incorporate biochemical cues into ETCs that enable spatial and temporal control of growth factors. Future efforts will investigate the cellular response by evaluating gene expression, quantifying angiogenic activity, and measuring the speed of growth factor consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=growth%20factor" title="growth factor">growth factor</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogel" title=" hydrogel"> hydrogel</a>, <a href="https://publications.waset.org/abstracts/search?q=peptide" title=" peptide"> peptide</a>, <a href="https://publications.waset.org/abstracts/search?q=angiogenesis" title=" angiogenesis"> angiogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular" title=" vascular"> vascular</a>, <a href="https://publications.waset.org/abstracts/search?q=patterning" title=" patterning"> patterning</a> </p> <a href="https://publications.waset.org/abstracts/148298/incorporation-of-growth-factors-onto-hydrogels-via-peptide-mediated-binding-for-development-of-vascular-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148298.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">163</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> Optimum Turbomachine Preliminary Selection for Power Regeneration in Vapor Compression Cool Production Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sayyed%20Benyamin%20Alavi">Sayyed Benyamin Alavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Cerri"> Giovanni Cerri</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Chennaoui"> Leila Chennaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Ambra%20Giovannelli"> Ambra Giovannelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Mazzoni"> Stefano Mazzoni </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Primary energy consumption and emissions of pollutants (including CO2) sustainability call to search methodologies to lower power absorption for unit of a given product. Cool production plants based on vapour compression are widely used for many applications: air conditioning, food conservation, domestic refrigerators and freezers, special industrial processes, etc. In the field of cool production, the amount of Yearly Consumed Primary Energy is enormous, thus, saving some percentage of it, leads to big worldwide impact in the energy consumption and related energy sustainability. Among various techniques to reduce power required by a Vapour Compression Cool Production Plant (VCCPP), the technique based on Power Regeneration by means of Internal Direct Cycle (IDC) will be considered in this paper. Power produced by IDC reduces power need for unit of produced Cool Power by the VCCPP. The paper contains basic concepts that lead to develop IDCs and the proposed options to use the IDC Power. Among various selections for using turbo machines, Best Economically Available Technologies (BEATs) have been explored. Based on vehicle engine turbochargers, they have been taken into consideration for this application. According to BEAT Database and similarity rules, the best turbo machine selection leads to the minimum nominal power required by VCCPP Main Compressor. Results obtained installing the prototype in “ad hoc” designed test bench will be discussed and compared with the expected performance. Forecasts for the upgrading VCCPP, various applications will be given and discussed. 4-6% saving is expected for air conditioning cooling plants and 15-22% is expected for cryogenic plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Refrigeration%20Plant" title="Refrigeration Plant">Refrigeration Plant</a>, <a href="https://publications.waset.org/abstracts/search?q=Vapour%20Pressure%20Amplifier" title=" Vapour Pressure Amplifier"> Vapour Pressure Amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=Compressor" title=" Compressor"> Compressor</a>, <a href="https://publications.waset.org/abstracts/search?q=Expander" title=" Expander"> Expander</a>, <a href="https://publications.waset.org/abstracts/search?q=Turbine" title=" Turbine"> Turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=Turbomachinery%20Selection" title=" Turbomachinery Selection"> Turbomachinery Selection</a>, <a href="https://publications.waset.org/abstracts/search?q=Power%20Saving" title=" Power Saving "> Power Saving </a> </p> <a href="https://publications.waset.org/abstracts/17883/optimum-turbomachine-preliminary-selection-for-power-regeneration-in-vapor-compression-cool-production-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17883.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">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Efficacy of Thrust on Basilar Spheno Synchondrosis in Boxers With Ocular Convergence Deficit.

A randomized controlled trial (RCT) pilot trial was performed at our physiotherapy practices. 30 adult subjects who practice the discipline of boxing were selected after an initial skimming defined by the Convergence Insufficiency Symptom Survey (CISS) test (results greater than or equal to 10) starting from the initial sample of 50 subjects; The 30 recruits were evaluated by an orthoptist using prisms to know the diopters of each eye and were divided into 2 groups (experimental group and control group). The members of the experimental group were subjected to manipulation of the lateral strain of sphenoid from the side contralateral to the eye that had fewer diopters and were subjected to a sequence of 3 ocular motor exercises immediately after manipulation. The control group, on the other hand, received only ocular motor treatment. A secondary outcome was also drawn up that demonstrated how changes in ocular motricity also affected cervical rotation. Analysis of the data showed that the experimental treatment was in the short term superior to the control group to astatistically significant extent both in terms of the prismatic delta of the right eye (0 OT median without manipulation and 10 OT median with manipulation) and that of the left eye (0 OT median without manipulation and 5 OT median with manipulation). Cervical rotation values also showed better values in the experimental group with a median of 4° in the right rotation without manipulation and 6° with thrust; the left rotation presented a median of 2° without manipulation and 7° with thrust. From the results that emerged, the treatment was effective. It would be desirable to increase the sample number and set up a timeline to see if the net improvements obtained in the short term will also be maintained in the medium to long term. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boxing" title="boxing">boxing</a>, <a href="https://publications.waset.org/abstracts/search?q=basilar%20spheno%20synchondrosis" title=" basilar spheno synchondrosis"> basilar spheno synchondrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ocular%20convergence%20deficit" title=" ocular convergence deficit"> ocular convergence deficit</a>, <a href="https://publications.waset.org/abstracts/search?q=osteopathic%20treatment" title=" osteopathic treatment"> osteopathic treatment</a> </p> <a href="https://publications.waset.org/abstracts/162167/efficacy-of-thrust-on-basilar-spheno-synchondrosis-in-boxers-with-ocular-convergence-deficit-comparison-of-thrust-and-therapeutic-exercise-pilot-experimental-randomized-controlled-trial-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162167.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">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Seismic Retrofit of Reinforced Concrete Structures by Highly Dissipative Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Sorace">Stefano Sorace</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20Terenzi"> Gloria Terenzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Mazzieri"> Giulia Mazzieri</a>, <a href="https://publications.waset.org/abstracts/search?q=Iacopo%20Costoli"> Iacopo Costoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The prolonged earthquake sequence that struck several urban agglomerations and villages in Central Italy, starting from 24 August 2016 through January 2017, highlighted once again the seismic vulnerability of pre-normative reinforced concrete (R/C) structures. At the same time, considerable damages were surveyed in recently retrofitted R/C buildings too, one of which also by means of a dissipative bracing system. The solution adopted for the latter did not expressly take into account the performance of non-structural elements, and namely of infills and partitions, confirming the importance of their dynamic interaction with the structural skeleton. Based on this consideration, an alternative supplemental damping-based retrofit solution for this representative building, i.e., a school with an R/C structure situated in the municipality of Norcia, is examined in this paper. It consists of the incorporation of dissipative braces equipped with pressurized silicone fluid viscous (FV) dampers, instead of the BRAD system installed in the building, the delayed activation of which -caused by the high stiffness of the constituting metallic dampers- determined the observed non-structural damages. Indeed, the alternative solution proposed herein, characterized by dissipaters with mainly damping mechanical properties, guarantees an earlier activation of the protective system. A careful assessment analysis, preliminarily carried out to simulate and check the case study building performance in originally BRAD-retrofitted conditions, confirms that the interstorey drift demand related to the Norcia earthquake's mainshock and aftershocks is beyond the response capacity of infills. The verification analyses developed on the R/C structure, including the FV-damped braces, highlight their higher performance, giving rise to a completely undamaged response both of structural and non-structural elements up to the basic design earthquake normative level of seismic action. <p class="card-text"><strong>Keywords:</strong> <a
