and thermal treatments (TT) on quality markers of strawberry nectar (12 °Brix, 3,3 pH) was studied before and after treatments. TT and HPP treatments ensured a 3-log aerobic bacteria inactivation. No significant difference was detected in terms of pH and °Brix. TT samples were less red (a* less positive) than all HPP treated samples, while all samples were less red than the control. Apparent viscosity was significantly increased in all the HPP treatments, at 10 1/s shear rate, control was 79.04±7.94 mPa•s and the 600 MPa-20 min treatment were 327.10±1.64 mPa•s. This work suggests that HPP treatments may maintain the quality markers of strawberry nectar better. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HPP" title="HPP">HPP</a>, <a href="https://publications.waset.org/abstracts/search?q=strawberry%20nectar" title=" strawberry nectar"> strawberry nectar</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour "> colour </a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title="viscosity">viscosity</a> </p> <a href="https://publications.waset.org/abstracts/147906/effect-of-high-pressure-and-thermal-treatments-on-quality-markers-of-strawberry-nectars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147906.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">63</span> Critical Approach to Define the Architectural Structure of a Health Prototype in a Rural Area of Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Domenico%20Chizzoniti">Domenico Chizzoniti</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Moscatelli"> Monica Moscatelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Letizia%20Cattani"> Letizia Cattani</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Preis"> Luca Preis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A primary healthcare facility in developing countries should be a multifunctional space able to respond to different requirements: Flexibility, modularity, aggregation and reversibility. These basic features could be better satisfied if applied to an architectural artifact that complies with the typological, figurative and constructive aspects of the context in which it is located. Therefore, the purpose of this paper is to identify a procedure that can define the figurative aspects of the architectural structure of the health prototype for the marginal areas of developing countries through a critical approach. The application context is the rural areas of the Northeast of Bahia in Brazil. The prototype should be located in the rural district of Quingoma, in the municipality of Lauro de Freitas, a particular place where there is still a cultural fusion of black and indigenous populations. Based on the historical analysis of settlement strategies and architectural structures in spaces of public interest or collective use, this paper aims to provide a procedure able to identify the categories and rules underlying typological and figurative aspects, in order to detect significant and generalizable elements, as well as materials and constructive techniques typically adopted in the rural areas of Brazil. The object of this work is therefore not only the recovery of certain constructive approaches but also the development of a procedure that integrates the requirements of the primary healthcare prototype with its surrounding economic, social, cultural, settlement and figurative conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architectural%20typology" title="architectural typology">architectural typology</a>, <a href="https://publications.waset.org/abstracts/search?q=developing%20countries" title=" developing countries"> developing countries</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20construction%20techniques" title=" local construction techniques"> local construction techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20health%20care." title=" primary health care."> primary health care.</a> </p> <a href="https://publications.waset.org/abstracts/65762/critical-approach-to-define-the-architectural-structure-of-a-health-prototype-in-a-rural-area-of-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65762.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">323</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">62</span> A Settlement Strategy for Health Facilities in Emerging Countries: A Case Study in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Domenico%20Chizzoniti">Domenico Chizzoniti</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Moscatelli"> Monica Moscatelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Letizia%20Cattani"> Letizia Cattani</a>, <a href="https://publications.waset.org/abstracts/search?q=Piero%20Favino"> Piero Favino</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Preis"> Luca Preis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A settlement strategy is to anticipate and respond the needs of existing and future communities through the provision of primary health care facilities in marginalized areas. Access to a health care network is important to improving healthcare coverage, often lacking, in developing countries. The study explores that a good sanitary system strategy of rural contexts brings advantages to an existing settlement: improving transport, communication, water and social facilities. The objective of this paper is to define a possible methodology to implement primary health care facilities in disadvantaged areas of emerging countries. In this research, we analyze the case study of Lauro de Freitas, a municipality in the Brazilian state of Bahia, part of the Metropolitan Region of Salvador, with an area of 57,662 <a href="https://it.wikipedia.org/wiki/Chilometro_quadrato" title="Chilometro quadrato">km²</a> and 194.641 inhabitants. The health localization system in Lauro de Freitas is an integrated process that involves not only geographical aspects, but also a set of factors: population density, epidemiological data, allocation of services, road networks, and more. Data were collected also using semi-structured interviews and questionnaires to the local population. Synthesized data suggest that moving away from the coast where there is the greatest concentration of population and services, a network of primary health care facilities is able to improve the living conditions of small-dispersed communities. Based on the health service needs of populations, we have developed a methodological approach that is particularly useful in rural and remote contexts in emerging countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare" title="healthcare">healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement%20strategy" title=" settlement strategy"> settlement strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20health" title=" urban health"> urban health</a>, <a href="https://publications.waset.org/abstracts/search?q=rural" title=" rural"> rural</a> </p> <a href="https://publications.waset.org/abstracts/64800/a-settlement-strategy-for-health-facilities-in-emerging-countries-a-case-study-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64800.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">368</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">61</span> Health Post A Sustainable Prototype for the Third World</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chizzoniti%20Domenico">Chizzoniti Domenico</a>, <a href="https://publications.waset.org/abstracts/search?q=Beggiora%20Klizia"> Beggiora Klizia</a>, <a href="https://publications.waset.org/abstracts/search?q=Cattani%20Letizia"> Cattani Letizia</a>, <a href="https://publications.waset.org/abstracts/search?q=Moscatelli%20Monica"> Moscatelli Monica</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper concerns the study of sustainable construction materials applied on the "Health Post", a prototype for the primary health care situated in alienated areas of the world. It's suitable for social and climatic Sub-Saharan context; however, it could be moved in other countries of the world with similar urgent needs. The idea is to create a Health Post with local construction materials that have a low environmental impact and promote the local workforce allowing reuse of traditional building techniques lowering production costs and transport. The aim of Primary Health Care Centre is to be a flexible and expandable structure identifying a modular form that can be repeated several times to expand its existing functions. In this way it could be not only a health care centre but also a socio-cultural facility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20costs%20building" title="low costs building">low costs building</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20construction%20materials" title=" sustainable construction materials"> sustainable construction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20construction%20system" title=" green construction system"> green construction system</a>, <a href="https://publications.waset.org/abstracts/search?q=prototype" title=" prototype"> prototype</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20care" title=" health care"> health care</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency" title=" emergency"> emergency</a> </p> <a href="https://publications.waset.org/abstracts/7899/health-post-a-sustainable-prototype-for-the-third-world" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7899.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">480</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">60</span> Characterization of the in 0.53 Ga 0.47 as n+nn+ Photodetectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zohra%20Mahi">Fatima Zohra Mahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Varani"> Luca Varani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present an analytical model for the calculation of the sensitivity, the spectral current noise and the detectivity for an optically illuminated In0.53Ga0.47As n+nn+ diode.

The importance of language assessment lies in helping to find the right test fit for purpose, in addition to achievement and proficiency. This study examines the validity of a new Arabic assessment tool, the Arabic Communicative Development Inventory ‘Arabic CDI’. It assesses the development of language in Arabic children in different Arabic countries, allowing to detect children with language delay. A concurrent validity is set to compare the Arabic CDI to the Arabic Language test. Twenty-three typically developing Egyptian healthy children and their mothers participated in this study. Their age is 24 months (+ or -) two weeks. The sample included 13 males and 10 females. Mothers completed the Arabic CDI either before or after the Arabic Language Test was conducted with the child. The score for comprehension in the Arabic CDI (M= 52.7, SD= 9.7) and words understood in the Arabic Language Test (M= 59.6, SD= 12.5) were strongly and positively correlated (r= .62, p= .002). At the same time, the scores for production in the Arabic CDI (M= 38.4, SD= 14.8) and words expressed in the Arabic Language Test (M= 52.1, SD= 16.3) were also strongly and positively correlated (r= .82, p= .000). The new Arabic CDI is an adequate tool for assessing the development of comprehension and production at Arabic children. In addition, it could be used for detecting children with language impairment. Standardization of the Arabic CDI across 18 different Arabic dialects in children aged 8 to 30 months is underway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arabic%20CDI" title="Arabic CDI">Arabic CDI</a>, <a href="https://publications.waset.org/abstracts/search?q=assessing%20children" title=" assessing children"> assessing children</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20development" title=" language development"> language development</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20impairment" title=" language impairment"> language impairment</a> </p> <a href="https://publications.waset.org/abstracts/64877/validating-the-arabic-communicative-development-inventory-for-assessing-the-development-of-language-in-arabic-speaking-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64877.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">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> The Classification Accuracy of Finance Data through Holder Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yeliz%20Karaca">Yeliz Karaca</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlo%20Cattani"> Carlo Cattani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on the local Holder exponent as a measure of the function regularity for time series related to finance data. In this study, the attributes of the finance dataset belonging to 13 countries (India, China, Japan, Sweden, France, Germany, Italy, Australia, Mexico, United Kingdom, Argentina, Brazil, USA) located in 5 different continents (Asia, Europe, Australia, North America and South America) have been examined.These countries are the ones mostly affected by the attributes with regard to financial development, covering a period from 2012 to 2017. Our study is concerned with the most important attributes that have impact on the development of finance for the countries identified. Our method is comprised of the following stages: (a) among the multi fractal methods and Brownian motion Holder regularity functions (polynomial, exponential), significant and self-similar attributes have been identified (b) The significant and self-similar attributes have been applied to the Artificial Neuronal Network (ANN) algorithms (Feed Forward Back Propagation (FFBP) and Cascade Forward Back Propagation (CFBP)) (c) the outcomes of classification accuracy have been compared concerning the attributes that have impact on the attributes which affect the countries’ financial development. This study has enabled to reveal, through the application of ANN algorithms, how the most significant attributes are identified within the relevant dataset via the Holder functions (polynomial and exponential function). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title="artificial neural networks">artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=finance%20data" title=" finance data"> finance data</a>, <a href="https://publications.waset.org/abstracts/search?q=Holder%20regularity" title=" Holder regularity"> Holder regularity</a>, <a href="https://publications.waset.org/abstracts/search?q=multifractals" title=" multifractals"> multifractals</a> </p> <a href="https://publications.waset.org/abstracts/90668/the-classification-accuracy-of-finance-data-through-holder-functions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90668.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">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Sunset Tourism for the Rebirth of Shrinking Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luca%20Lezzerini">Luca Lezzerini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Albania is suffering a continuous shrinking of its population and demographic distribution that faces all the problems connected with age increase.

The research method is the questionnaire, aimed at investigating the choices of tourists in the area of mobility, their perception of the quality of life and their level of appreciation of neighbourhoods, landmarks and infrastructures. There is an obvious link between the quality of life and the quality of the tourist experience, but it is difficult to measure it. Through this questionnaire, we hope to have made a small contribution to the understanding of the perceptive sphere of the individual and his choices in terms of behaviour, which is an essential element of any strategy for tourism marketing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lisbon" title="Lisbon">Lisbon</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility" title=" mobility"> mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=hospitality" title=" hospitality"> hospitality</a> </p> <a href="https://publications.waset.org/abstracts/2823/lisbon-experience-mobility-quality-of-life-and-tourist-image-a-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2823.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">421</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">55</span> Full-Wave Analysis of Magnetic Meta-Surfaces for Microwave Component Applications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Hardly%20Joseph">Christopher Hardly Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Pelagalli"> Nicola Pelagalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20Mencarelli"> Davide Mencarelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Pierantoni"> Luca Pierantoni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this contribution, we report the electromagnetic response of a split ring resonator (SRR) based magnetic metamaterial unit cell in free space nature by means of a full-wave electromagnetic simulation.

Promising results related to the acceptance of CAs in healthcare have been accomplished. In that regard, understanding how to design CAs in a way that patients trust their recommendations and decisions constitutes an important area of research. Our study examines self-disclosure and transparency as drivers of trust to enhance the medical assistance of CAs for patients. Accordingly, we examined the effects of self-disclosure and transparency on patients trust and service satisfaction by conducting an online experiment with 136 participants. Our results show that the expression of both self-disclosure and conversational agents transparency leads to an increased perception of trust but does not necessarily improve the service satisfaction. Therefore, developers should implement self-disclosure and transparency to create a trustworthy environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conversational%20agent" title="conversational agent">conversational agent</a>, <a href="https://publications.waset.org/abstracts/search?q=transparency" title=" transparency"> transparency</a>, <a href="https://publications.waset.org/abstracts/search?q=self-disclosure" title=" self-disclosure"> self-disclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a> </p> <a href="https://publications.waset.org/abstracts/156760/effects-of-self-disclosure-and-transparency-on-conversational-agents-in-a-healthcare-related-decision-support-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156760.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">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Early Return to Play in Football Player after ACL Injury: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Milani">Nicola Milani</a>, <a href="https://publications.waset.org/abstracts/search?q=Carla%20Bellissimo"> Carla Bellissimo</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20Pogliana"> Davide Pogliana</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20Panzin"> Davide Panzin</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Garlaschelli"> Luca Garlaschelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Facchinetti"> Giulia Facchinetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Casson"> Claudia Casson</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Marazzina"> Luca Marazzina</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Sartori"> Andrea Sartori</a>, <a href="https://publications.waset.org/abstracts/search?q=Simone%20Rivaroli"> Simone Rivaroli</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Konin"> Jeff Konin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The patient is a 26 year-old male amateur football player from Milan, Italy; (81kg; 185cm; BMI 23.6 kg/m²). He sustained a non-contact anterior cruciate ligament tear to his right knee in June 2021. In September 2021, his right knee ligament was reconstructed using a semitendinosus graft. The injury occurred during a football match on natural grass with typical shoes on a warm day (32 degrees celsius). Playing as a defender he sustained the injury during a change of direction, where the foot was fixated on the grass. He felt pain and was unable to continue playing the match. The surgeon approved his rehabilitation to begin two weeks post-operative. The initial physiotherapist assessment determined performing two training sessions per day within the first three months. In the first three weeks, the pain was 4/10 on Numerical Rating Scale (NRS), no swelling, a range of motion was 0-110°, with difficulty fully extending his knee and minimal quadriceps activation. Crutches were discontinued at four weeks with improved walking. Active exercise, electrostimulator, physical therapy, massages, osteopathy, and passive motion were initiated. At week 6, he completed his first functional movement screen; the score was 16/21 with no pain and no swelling. At week 8, the isokinetic test showed a 23% differential deficit between the two legs in maximum strength (at 90°/s). At week 10, he improved to 15% of injury-induced deficit which suggested he was ready to start running. At week 12, the athlete sustained his first threshold test. At week 16, he performed his first return to sports movement assessment, which revealed a 10% stronger difference between the legs. At week 16, he had his second threshold test. At week 17, his first on-field test revealed a 5% differential deficit between the two legs in the hop test. At week 18, isokinetic test demonstrates that the uninjured leg was 7% stronger than the recovering leg in maximum strength (at 90°/s). At week 20, his second on-field test revealed a 2% difference in hop test; at week 21, his third isokinetic test demonstrated a difference of 5% in maximum strength (at 90°/s). At week 21, he performed his second return to sports movement assessment which revealed a 2% difference between the limbs. Since it was the end of the championship, the team asked him to partake in the playoffs; moreover the player was very motivated to participate in the playoffs also because he was the captain of the team. Together with the player and the team, we decided to let him play even though we were aware of a heightened risk of injury than what is reported in the literature because of two factors: biological recovery times and the results of the tests we performed. In the decision making process about the athlete’s recovery time, it is important to balance the information available from the literature with the desires of the patient to avoid frustration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ACL" title="ACL">ACL</a>, <a href="https://publications.waset.org/abstracts/search?q=football" title=" football"> football</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=return%20to%20play" title=" return to play"> return to play</a> </p> <a href="https://publications.waset.org/abstracts/152833/early-return-to-play-in-football-player-after-acl-injury-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152833.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">50</span> Networked Radar System to Increase Safety of Urban Railroad Crossing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Saponara">Sergio Saponara</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Fanucci"> Luca Fanucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Riccardo%20Cassettari"> Riccardo Cassettari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruggero%20Piernicola"> Ruggero Piernicola</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Righetto"> Marco Righetto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper presents an innovative networked radar system for detection of obstacles in a railway level crossing scenario.

The MS is also connected to the National Railway Information and Signaling System to communicate in real-time the level crossing status. The architecture is compliant with the highest Safety Integrity Level (SIL4) of the CENELEC standard. The number of radar sensors used is configurable at set-up time and depends on how large the level crossing area can be. At least two sensors are expected and up four can be used for larger areas. The whole processing chain that elaborates the output sensor signals, as well as the communication interface, is fully-digital, was designed in VHDL code and implemented onto a Xilinx Virtex 6. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radar%20for%20safe%20mobility" title="radar for safe mobility">radar for safe mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=railroad%20crossing" title=" railroad crossing"> railroad crossing</a>, <a href="https://publications.waset.org/abstracts/search?q=railway" title=" railway"> railway</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20safety" title=" transport safety"> transport safety</a> </p> <a href="https://publications.waset.org/abstracts/31337/networked-radar-system-to-increase-safety-of-urban-railroad-crossing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31337.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">480</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">49</span> The Effects of Big 6+6 Skill Training on Daily Living Skills for an Adolescent with Intellectual Disability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luca%20Vascelli">Luca Vascelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Iacomini"> Silvia Iacomini</a>, <a href="https://publications.waset.org/abstracts/search?q=Giada%20Gueli"> Giada Gueli</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Cavallini"> Francesca Cavallini</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlo%20Cavallini"> Carlo Cavallini</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Berardo"> Federica Berardo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was conducted to evaluate the effect of training on Big 6 + 6 motor skills to promote daily living skills.

Rock failure is most often preceded by a tiny elastic movement in the failure area and by the appearance of micro-cracks. These micro-cracks could be detected at the soil surface and represent useful earth-quakes precursors. The aim of this study was to verify whether tiny raw acceleration signals (in the 10⁻¹ to 10⁻⁴ cm/s² range) prior to the arrival of main primary-waves could be exploitable and related to earthquakes magnitude. Mathematical tools such as Fast Fourier Transform (FFT), moving average and wavelets have been applied on raw acceleration data available on the ITACA web site, and the study focused on one of the most unpredictable earth-quakes, i.e., the August 24th, 2016 at 01H36 one that occurred in the central Italy area. It appeared that these tiny acceleration signals preceding main P-waves have different patterns both on frequency and time domains for high magnitude earthquakes compared to lower ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake" title="earthquake">earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=accelerometer" title=" accelerometer"> accelerometer</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake%20forecasting" title=" earthquake forecasting"> earthquake forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=seism" title=" seism"> seism</a> </p> <a href="https://publications.waset.org/abstracts/109727/early-detection-of-major-earthquakes-using-broadband-accelerometers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109727.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">144</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> Introducing Design Principles for Clinical Decision Support Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luca%20Martignoni">Luca Martignoni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing usage of clinical decision support systems in healthcare and the demand for software that enables doctors to take informed decisions is changing everyday clinical practice. However, as technology advances not only are the benefits of technology growing, but so are the potential risks. A growing danger is the doctors’ over-reliance on the proposed decision of the clinical decision support system, leading towards deskilling and rash decisions by doctors. In that regard, identifying doctors' requirements for software and developing approaches to prevent technological over-reliance is of utmost importance. In this paper, we report the results of a design science research study, focusing on the requirements and design principles of ultrasound software. We conducted a total of 15 interviews with experts about poten-tial ultrasound software functions. Subsequently, we developed meta-requirements and design principles to design future clinical decision support systems efficiently and as free from the occur-rence of technological over-reliance as possible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clinical%20decision%20support%20systems" title="clinical decision support systems">clinical decision support systems</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20over-reliance" title=" technological over-reliance"> technological over-reliance</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20principles" title=" design principles"> design principles</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20science%20research" title=" design science research"> design science research</a> </p> <a href="https://publications.waset.org/abstracts/164680/introducing-design-principles-for-clinical-decision-support-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164680.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">100</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> Analytical Terahertz Characterization of In0.53Ga0.47As Transistors and Homogenous Diodes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelmadjid%20Mammeri">Abdelmadjid Mammeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zohra%20Mahi"> Fatima Zohra Mahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Varani"> Luca Varani</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20Marinchoi"> H.

The development of the small-signal admittance takes into account the longitudinal and transverse electric fields through a pseudo two-dimensional approximation of the Poisson equation. The frequency-dependent of the small-signal admittance response is determined by the total currents and the potentials matrix relation between the gate and the drain terminals. The noise is evaluated by using the real part of the transistor/diode admittance under a small-signal perturbation. The analytical results show that the admittance spectrum exhibits a series of resonant peaks corresponding to the excitation of plasma waves. The appearance of the resonance is discussed and analyzed as functions of the channel length and the temperature. The model can be used, on one hand; to control the appearance of the plasma resonances, and on other hand; can give significant information about the noise frequency dependence in the InGaAs transistor and diode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=InGaAs%20transistors" title="InGaAs transistors">InGaAs transistors</a>, <a href="https://publications.waset.org/abstracts/search?q=InGaAs%20diode" title=" InGaAs diode"> InGaAs diode</a>, <a href="https://publications.waset.org/abstracts/search?q=admittance" title=" admittance"> admittance</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant%20peaks" title=" resonant peaks"> resonant peaks</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20waves" title=" plasma waves"> plasma waves</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20model" title=" analytical model"> analytical model</a> </p> <a href="https://publications.waset.org/abstracts/45170/analytical-terahertz-characterization-of-in053ga047as-transistors-and-homogenous-diodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45170.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">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> 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">44</span> Reducing Weight and Fuel Consumption of Civil Aircraft by EML</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luca%20Bertola">Luca Bertola</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20Cox"> Tom Cox</a>, <a href="https://publications.waset.org/abstracts/search?q=Pat%20Wheeler"> Pat Wheeler</a>, <a href="https://publications.waset.org/abstracts/search?q=Seamus%20Garvey"> Seamus Garvey</a>, <a href="https://publications.waset.org/abstracts/search?q=Herve%20Morvan"> Herve Morvan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electromagnetic launch systems have been proposed for military applications to accelerate jet planes on aircraft carriers. This paper proposes the implementation of similar technology to aid civil aircraft take-off, which can provide significant economic, environmental and technical benefits. Assisted launch has the potential of reducing ground noise and emissions near airports and improving overall aircraft efficiency through reducing engine thrust requirements. This paper presents a take-off performance analysis for an Airbus A320-200 taking off with and without the assistance of the electromagnetic catapult. Assisted take-off allows for a significant reduction in take-off field length, giving more capacity with existing airport footprints and reducing the necessary footprint of new airports, which will both reduce costs and increase the number of suitable sites. The electromagnetic catapult may allow the installation of smaller engines with lower rated thrust. The consequent fuel consumption and operational cost reduction are estimated.

The objective of the investment project selection problem is to choose the best project among the set of projects, seeking investment, or to rank all projects in descending order. The project selection is made considering a set of weighted attributes. To evaluate the attributes in our approach, expert assessments are used.

Otsdaq is an online DAQ software suite with a focus on flexibility and scalability while providing a multi-user, web-based interface accessible through the Chrome or Firefox web browser. The detector read out controller (ROC) from the tracker and calorimeter stream out zero-suppressed data continuously to the data transfer controller (DTC). Data is then read over the PCIe bus to a software filter algorithm that selects events which are finally combined with the data flux that comes from a cosmic ray veto system (CRV). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trigger" title="trigger">trigger</a>, <a href="https://publications.waset.org/abstracts/search?q=daq" title=" daq"> daq</a>, <a href="https://publications.waset.org/abstracts/search?q=mu2e" title=" mu2e"> mu2e</a>, <a href="https://publications.waset.org/abstracts/search?q=Fermilab" title=" Fermilab"> Fermilab</a> </p> <a href="https://publications.waset.org/abstracts/130901/the-trigger-daq-system-in-the-mu2e-experiment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130901.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">155</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> Application of Italian Guidelines for Existing Bridge Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Menichini">Giovanni Menichini</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Giacomo%20Morano"> Salvatore Giacomo Morano</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20Terenzi"> Gloria Terenzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Salvatori"> Luca Salvatori</a>, <a href="https://publications.waset.org/abstracts/search?q=Maurizio%20Orlando"> Maurizio Orlando</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The “Guidelines for Risk Classification, Safety Assessment, and Structural Health Monitoring of Existing Bridges” were recently approved by the Italian Government to define technical standards for managing the national network of existing bridges. These guidelines provide a framework for risk mitigation and safety assessment of bridges, which are essential elements of the built environment and form the basis for the operation of transport systems. Within the guideline framework, a workflow based on three main points was proposed: (1) risk-based, i.e., based on typical parameters of hazard, vulnerability, and exposure; (2) multi-level, i.e., including six assessment levels of increasing complexity; and (3) multirisk, i.e., assessing structural/foundational, seismic, hydrological, and landslide risks. The paper focuses on applying the Italian Guidelines to specific case studies, aiming to identify the parameters that predominantly influence the determination of the “class of attention”. The significance of each parameter is determined via sensitivity analysis. Additionally, recommendations for enhancing the process of assigning the class of attention are proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20safety%20assessment" title="bridge safety assessment">bridge safety assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=Italian%20guidelines%20implementation" title=" Italian guidelines implementation"> Italian guidelines implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20classification" title=" risk classification"> risk classification</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20health%20monitoring" title=" structural health monitoring"> structural health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/184665/application-of-italian-guidelines-for-existing-bridge-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184665.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">56</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> First Surveillance Results Bring No Evidence of SARS-CoV-2 Spillback in Bats of Central-Southern Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiba%20Dakroub">Hiba Dakroub</a>, <a href="https://publications.waset.org/abstracts/search?q=Danilo%20Russo"> Danilo Russo</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Cistrone"> Luca Cistrone</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Serra"> Francesco Serra</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanna%20Fusco"> Giovanna Fusco</a>, <a href="https://publications.waset.org/abstracts/search?q=Esterina%20De%20Carlo"> Esterina De Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Grazia%20Amoroso"> Maria Grazia Amoroso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The question of the origin of SARS-CoV-2 and the cycle of transmission between humans and animals is still unanswered. One serious concern associated with the SARS-CoV-2 pandemic is that the virus might spill back from humans to wildlife, which would render some animal species reservoirs of the human virus. The aim of the present study is to monitor the potential risk of SARS-CoV-2 reverse infection from humans to bats, by performing bat surveillance from different sites in Central-Southern Italy. We collected 240 droppings or saliva from 129 bats and tested them using specific and general primers of SARS-COV-2 and coronaviruses respectively. All samples, including 127 nasal swabs and 113 fecal droppings resulted negative for SARS-COV-2, and these results were confirmed by testing the samples with the Droplet Digital PCR. Also, an end-point RT-PCR was performed and no sample showed specific bands. The absence of SARS-CoV-2 in the bats we surveyed is a first step towards a better understanding of reverse transmission to bats of this virus. We hope our first contribution will encourage the establishment of systematic surveillance of wildlife, and specifically bats, to help prevent reverse zoonotic episodes that would jeopardize human health as well as biodiversity conservation and management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coronaviruses" title="coronaviruses">coronaviruses</a>, <a href="https://publications.waset.org/abstracts/search?q=bats" title=" bats"> bats</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonotic%20viruses" title=" zoonotic viruses"> zoonotic viruses</a>, <a href="https://publications.waset.org/abstracts/search?q=spillback" title=" spillback"> spillback</a>, <a href="https://publications.waset.org/abstracts/search?q=SARS-CoV-2" title=" SARS-CoV-2"> SARS-CoV-2</a> </p> <a href="https://publications.waset.org/abstracts/150760/first-surveillance-results-bring-no-evidence-of-sars-cov-2-spillback-in-bats-of-central-southern-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150760.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">39</span> Decision Making Approach through Generalized Fuzzy Entropy Measure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20D.%20Arora">H.

Uncertainty emerges as one has less information than the total information required describing a system and its environment. Uncertainty and information are so closely associated that the information provided by an experiment for example, is equal to the amount of uncertainty removed. It may be pertinent to point out that uncertainty manifests itself in several forms and various kinds of uncertainties may arise from random fluctuations, incomplete information, imprecise perception, vagueness etc. For instance, one encounters uncertainty due to vagueness in communication through natural language. Uncertainty in this sense is represented by fuzziness resulting from imprecision of meaning of a concept expressed by linguistic terms. Fuzzy set concept provides an appropriate mathematical framework for dealing with the vagueness. Both information theory, proposed by Shannon (1948) and fuzzy set theory given by Zadeh (1965) plays an important role in human intelligence and various practical problems such as image segmentation, medical diagnosis etc. Numerous approaches and theories dealing with inaccuracy and uncertainty have been proposed by different researcher. In the present communication, we generalize fuzzy entropy proposed by De Luca and Termini (1972) corresponding to Shannon entropy(1948). Further, some of the basic properties of the proposed measure were examined. We also applied the proposed measure to the real life decision making problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entropy" title="entropy">entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20sets" title=" fuzzy sets"> fuzzy sets</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20entropy" title=" fuzzy entropy"> fuzzy entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20fuzzy%20entropy" title=" generalized fuzzy entropy"> generalized fuzzy entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a> </p> <a href="https://publications.waset.org/abstracts/26513/decision-making-approach-through-generalized-fuzzy-entropy-measure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26513.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">448</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> Procedure for Impact Testing of Fused Recycled Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Halley">David Halley</a>, <a href="https://publications.waset.org/abstracts/search?q=Tyra%20Oseng-Rees"> Tyra Oseng-Rees</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Pagano"> Luca Pagano</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20A%20Ferriz-Papi"> Juan A Ferriz-Papi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recycled glass material is made from 100% recycled bottle glass and consumes less energy than re-melt technology. It also uses no additives in the manufacturing process allowing the recycled glass material, in principal, to go back to the recycling stream after end-of-use, contributing to the circular economy with a low ecological impact. The aim of this paper is to investigate the procedure for testing the recycled glass material for impact resistance, so it can be applied to pavements and other surfaces which are at risk of impact during service. A review of different impact test procedures for construction materials was undertaken, comparing methodologies and international standards applied to other materials such as natural stone, ceramics and glass. A drop weight impact testing machine was designed and manufactured in-house to perform these tests. As a case study, samples of the recycled glass material were manufactured with two different thicknesses and tested. The impact energy was calculated theoretically, obtaining results with 5 and 10 J. The results on the material were subsequently discussed. Improvements on the procedure can be made using high speed video technology to calculate velocity just before and immediately after the impact to know the absorbed energy. The initial results obtained in this procedure were positive although repeatability needs to be developed to obtain a correlation of results and finally be able to validate the procedure. The experiment with samples showed the practicality of this procedure and application to the recycled glass material impact testing although further research needs to be developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20materials" title="construction materials">construction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=drop%20weight%20impact" title=" drop weight impact"> drop weight impact</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20testing" title=" impact testing"> impact testing</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20glass" title=" recycled glass"> recycled glass</a> </p> <a href="https://publications.waset.org/abstracts/79723/procedure-for-impact-testing-of-fused-recycled-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79723.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">296</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> A Mathematical Investigation of the Turkevich Organizer Theory in the Citrate Method for the Synthesis of Gold Nanoparticles </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Agunloye">Emmanuel Agunloye</a>, <a href="https://publications.waset.org/abstracts/search?q=Asterios%20Gavriilidis"> Asterios Gavriilidis</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Mazzei"> Luca Mazzei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gold nanoparticles are commonly synthesized by reducing chloroauric acid with sodium citrate. This method, referred to as the citrate method, can produce spherical gold nanoparticles (NPs) in the size range 10-150 nm. Gold NPs of this size are useful in many applications. However, the NPs are usually polydisperse and irreproducible. A better understanding of the synthesis mechanisms is thus required. This work thoroughly investigated the only model that describes the synthesis. This model combines mass and population balance equations, describing the NPs synthesis through a sequence of chemical reactions. Chloroauric acid reacts with sodium citrate to form aurous chloride and dicarboxy acetone. The latter organizes aurous chloride in a nucleation step and concurrently degrades into acetone. The unconsumed precursor then grows the formed nuclei. However, depending on the pH, both the precursor and the reducing agent react differently thus affecting the synthesis. In this work, we investigated the model for different conditions of pH, temperature and initial reactant concentrations. To solve the model, we used Parsival, a commercial numerical code, whilst to test it, we considered various conditions studied experimentally by different researchers, for which results are available in the literature. The model poorly predicted the experimental data. We believe that this is because the model does not account for the acid-base properties of both chloroauric acid and sodium citrate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citrate%20method" title="citrate method">citrate method</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoparticles" title=" gold nanoparticles"> gold nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=Parsival" title=" Parsival"> Parsival</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20balance%20equations" title=" population balance equations"> population balance equations</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkevich%20organizer%20theory" title=" Turkevich organizer theory"> Turkevich organizer theory</a> </p> <a href="https://publications.waset.org/abstracts/56126/a-mathematical-investigation-of-the-turkevich-organizer-theory-in-the-citrate-method-for-the-synthesis-of-gold-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56126.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">203</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> MIMIC: A Multi Input Micro-Influencers Classifier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simone%20Leonardi">Simone Leonardi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Ardito"> Luca Ardito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Micro-influencers are effective elements in the marketing strategies of companies and institutions because of their capability to create an hyper-engaged audience around a specific topic of interest. In recent years, many scientific approaches and commercial tools have handled the task of detecting this type of social media users. These strategies adopt solutions ranging from rule based machine learning models to deep neural networks and graph analysis on text, images, and account information. This work compares the existing solutions and proposes an ensemble method to generalize them with different input data and social media platforms. The deployed solution combines deep learning models on unstructured data with statistical machine learning models on structured data. We retrieve both social media accounts information and multimedia posts on Twitter and Instagram. These data are mapped into feature vectors for an eXtreme Gradient Boosting (XGBoost) classifier. Sixty different topics have been analyzed to build a rule based gold standard dataset and to compare the performances of our approach against baseline classifiers. We prove the effectiveness of our work by comparing the accuracy, precision, recall, and f1 score of our model with different configurations and architectures. We obtained an accuracy of 0.91 with our best performing model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title="deep learning">deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=gradient%20boosting" title=" gradient boosting"> gradient boosting</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-influencers" title=" micro-influencers"> micro-influencers</a>, <a href="https://publications.waset.org/abstracts/search?q=NLP" title=" NLP"> NLP</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a> </p> <a href="https://publications.waset.org/abstracts/148293/mimic-a-multi-input-micro-influencers-classifier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148293.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">183</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> Non-Destructive Testing of Selective Laser Melting Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luca%20Collini">Luca Collini</a>, <a href="https://publications.waset.org/abstracts/search?q=Michele%20Antolotti"> Michele Antolotti</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Schiavi"> Diego Schiavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At present, complex geometries within production time shrinkage, rapidly increasing demand, and high-quality standard requirement make the non-destructive (ND) control of additively manufactured components indispensable means. On the other hand, a technology gap and the lack of standards regulating the methods and the acceptance criteria indicate the NDT of these components a stimulating field to be still fully explored. Up to date, penetrant testing, acoustic wave, tomography, radiography, and semi-automated ultrasound methods have been tested on metal powder based products so far. External defects, distortion, surface porosity, roughness, texture, internal porosity, and inclusions are the typical defects in the focus of testing. Detection of density and layers compactness are also been tried on stainless steels by the ultrasonic scattering method. In this work, the authors want to present and discuss the radiographic and the ultrasound ND testing on additively manufactured Ti₆Al₄V and inconel parts obtained by the selective laser melting (SLM) technology. In order to test the possibilities given by the radiographic method, both X-Rays and γ-Rays are tried on a set of specifically designed specimens realized by the SLM. The specimens contain a family of defectology, which represent the most commonly found, as cracks and lack of fusion. The tests are also applied to real parts of various complexity and thickness. A set of practical indications and of acceptance criteria is finally drawn. <p class="card-text"><strong>Keywords:</strong> <a
