It is difficult to predict sound absorbing coefficient because of several material layers. So, many experimental tunings are required to achieve the target of sound absorption. Therefore, while the car interior materials are developed, so much time and money is spent. In this study, we present a method to predict the sound absorbing performance of the material with multi-layer using physical properties of each material. The properties are predicted by Foam-X software using the sound absorption coefficient data measured by impedance tube. Then, we will compare and analyze the predicted sound absorption coefficient with the data measured by scaled reverberation chamber and impedance tubes for a prototype. If the method is used instead of experimental tuning in the development of car interior material, the time and money can be saved, and then, the development effort can be reduced because it can be optimized by simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-layer%20nonwoven" title="multi-layer nonwoven">multi-layer nonwoven</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20coefficient" title=" sound absorption coefficient"> sound absorption coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=scaled%20reverberation%20chamber" title=" scaled reverberation chamber"> scaled reverberation chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance%20tubes" title=" impedance tubes"> impedance tubes</a> </p> <a href="https://publications.waset.org/abstracts/60069/the-prediction-of-sound-absorbing-coefficient-for-multi-layer-non-woven" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60069.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">376</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">749</span> Preliminary Design of Maritime Energy Management System: Naval Architectural Approach to Resolve Recent Limitations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyong%20Jeong">Seyong Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinmo%20Park"> Jinmo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinhyoun%20Park"> Jinhyoun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Boram%20Kim"> Boram Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoungsoo%20Ahn"> Kyoungsoo Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy management in the maritime industry is being required by economics and in conformity with new legislative actions taken by the International Maritime Organization (IMO) and the European Union (EU). In response, the various performance monitoring methodologies and data collection practices have been examined by different stakeholders. While many assorted advancements in operation and technology are applicable, their adoption in the shipping industry stays small. This slow uptake can be considered due to many different barriers such as data analysis problems, misreported data, and feedback problems, etc. This study presents a conceptual design of an energy management system (EMS) and proposes the methodology to resolve the limitations (e.g., data normalization using naval architectural evaluation, management of misrepresented data, and feedback from shore to ship through management of performance analysis history). We expect this system to make even short-term charterers assess the ship performance properly and implement sustainable fleet control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20normalization" title="data normalization">data normalization</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20management%20system" title=" energy management system"> energy management system</a>, <a href="https://publications.waset.org/abstracts/search?q=naval%20architectural%20evaluation" title=" naval architectural evaluation"> naval architectural evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=ship%20performance%20analysis" title=" ship performance analysis"> ship performance analysis</a> </p> <a href="https://publications.waset.org/abstracts/61540/preliminary-design-of-maritime-energy-management-system-naval-architectural-approach-to-resolve-recent-limitations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61540.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">449</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">748</span> Comparison of Techniques for Detection and Diagnosis of Eccentricity in the Air-Gap Fault in Induction Motors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abrah%C3%A3o%20S.%20Fontes">Abrahão S.

Several maintenance techniques are applied to increase the operating time and the lifespan of these motors. Among these, the predictive maintenance techniques such as Motor Current Signature Analysis (MCSA), Motor Square Current Signature Analysis (MSCSA), Park's Vector Approach (PVA) and Park's Vector Square Modulus (PVSM) are used to detect and diagnose faults in electric motors, characterized by patterns in the stator current frequency spectrum. In this article, these techniques are applied and compared on a real motor, which has the fault of eccentricity in the air-gap. It was used as a theoretical model of an electric induction motor without fault in order to assist comparison between the stator current frequency spectrum patterns with and without faults. Metrics were purposed and applied to evaluate the sensitivity of each technique fault detection. The results presented here show that the above techniques are suitable for the fault of eccentricity in the air gap, whose comparison between these showed the suitability of each one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eccentricity%20in%20the%20air-gap" title="eccentricity in the air-gap">eccentricity in the air-gap</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20diagnosis" title=" fault diagnosis"> fault diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20motors" title=" induction motors"> induction motors</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20maintenance" title=" predictive maintenance"> predictive maintenance</a> </p> <a href="https://publications.waset.org/abstracts/62315/comparison-of-techniques-for-detection-and-diagnosis-of-eccentricity-in-the-air-gap-fault-in-induction-motors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62315.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">350</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">747</span> Entropy Generation Analysis of Heat Recovery Vapor Generator for Ammonia-Water Mixture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chul%20Ho%20Han">Chul Ho Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung%20Hoon%20Kim"> Kyoung Hoon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper carries out a performance analysis based on the first and second laws of thermodynamics for heat recovery vapor generator (HRVG) of ammonia-water mixture when the heat source is low-temperature energy in the form of sensible heat.

The paradigms of industrial heritage research tend to explore from the perspective of space analysis, which concerned less about the cultural regeneration and the development of local culture. The paradigms of cultural quarter research use to from the perspective of creative economy and urban planning, concerned less about the social impacts and the interaction between residents and industrial sites. This research combines these two research areas of industrial heritage and cultural quarter, and focus on the social and cultural aspects. The transformation from the industrial heritage into a cultural park not only enhances the cultural capital and the quality of residents’ lives, but also preserves the unique local values. Internally it shapes the local identity, while externally establishes the image of the city. This paper uses Westergasfabriek Cultural Park in Amsterdam as the case study, through literature analysis, field work, and depth interview to explore how the cultural regeneration transforms industrial heritage. In terms of the planners’ and residents’ point of view adopt the theory of community participation, social capital, and sense of place to analyze the social impact of the industrial heritage transformation. The research finding is through cultural regeneration policies like holding cultural activities, building up public space, social network and public-private partnership, and adopting adaptive reuse to fulfil the people’s need and desire and reach the social cohesion. Finally, the study will examine the transformation of Taiwan's industrial heritage into cultural and creative quarters. The results are expected to use the operating experience of the Amsterdam cases and provide directions for Taiwan’s industrial heritage management to meet the cultural, social, economic symbiosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20regeneration" title="cultural regeneration">cultural regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20participation" title=" community participation"> community participation</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20capital" title=" social capital"> social capital</a>, <a href="https://publications.waset.org/abstracts/search?q=sense%20of%20place" title=" sense of place"> sense of place</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20heritage%20transformation" title=" industrial heritage transformation"> industrial heritage transformation</a> </p> <a href="https://publications.waset.org/abstracts/13544/cultural-regeneration-and-social-impacts-of-industrial-heritage-transformation-the-case-of-westergasfabriek-cultural-park-netherland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13544.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">504</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">745</span> Visitor's Perception toward Boating in Silver River, Florida</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Manafian">Hoda Manafian</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Holland"> Stephen Holland</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Silver Springs are one of Florida's first tourist attractions. They are one of the largest artesian spring formations in the world, producing nearly 550 million gallons of crystal-clear water daily that is one of the most popular sites for water-based leisure activities. As part of managing the use of a state park, the state is interested in establishing a baseline count of number of boating users to compare this to the quality of the natural resources and environment in the park. Understanding the status of the environmental resources and also the human recreational experience is the main objective of the project. Two main goals of current study are 1) to identify the distribution of different types of watercrafts (kayak, canoe, motor boat, Jet Ski, paddleboard and pontoon). 2) To document the level of real crowdedness in the river during different seasons, months, and hours of each day based on the reliable information gained from camera versus self-reported method by tourists themselves in the past studies (the innovative achievement of this study). In line with these objectives, on-site surveys and also boat counting using a time-lapse camera at the Riverside launch was done during 12 months of 2015. 700 on-site surveys were conducted at three watercraft boat ramp sites (Rays Wayside, Riverside launch area, Ft. King Waterway) of recreational users. We used Virtualdub and ImageJ software for counting boats for meeting the first and second goals, since this two software can report even the hour of presence of watercraft in the water in addition to the number of users and the type of watercraft. The most crowded hours were between 9-11AM from February to May and kayak was the most popular watercraft. The findings of this research can make a good foundation for better management in this state park in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eco-tourism" title="eco-tourism">eco-tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=Florida%20state" title=" Florida state"> Florida state</a>, <a href="https://publications.waset.org/abstracts/search?q=visitors%27%20perception" title=" visitors' perception"> visitors' perception</a>, <a href="https://publications.waset.org/abstracts/search?q=water-based%20recreation" title=" water-based recreation"> water-based recreation</a> </p> <a href="https://publications.waset.org/abstracts/49800/visitors-perception-toward-boating-in-silver-river-florida" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49800.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">744</span> Assessment Proposal to Establish the First Geo-Park in Egypt at Abu-Roash Area, Cairo </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kholoud%20Abdelmaksoud">Kholoud Abdelmaksoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Emam"> Mahmoud Emam</a>, <a href="https://publications.waset.org/abstracts/search?q=Wael%20%20Al-Metwaly"> Wael Al-Metwaly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Egypt is known as cradle of civilization due to its ancient history and archeological sites, but Egypt possess also a cradle of Geo-sites, which qualify it to be listed as one of the most important Geo-heritage sites all over the country. Geology and landscape in Abu-Roash area is considered as one of the most important geological places (geo-sites) inside Cairo which help us to know and understand geology and geologic processes, so the area is used mainly for geological education purposes, also the area contain an archeological sites; pyramid complex, tombs, and Coptic monastery which give the area unique importance. Abu-Roash area is located inside Cairo 9 km north of the Giza Pyramids, which make the accessibility to the area easy and safe, the geology of Abu-Roash constitutes a complex Cretaceous sedimentary succession mass with showing outstanding tectonic features (Syrian Arc system event), these features are considered as a Geo-heritage, which will be the main designation of ‘Geo-parks’ establishing. The research is dealing with the numerous geo-sites found in the area, and its geologic and archeological importance, the relation between geo-sites and archeology, also the research proposed a detailed maps for these sites depicting Geo-routes and the hazardous places surrounding Abu-Roash area. The research is proposing a new proposal not applied in Egypt before, establishing a Geo-park, to promote this unique geo-heritage from hazardous factors and anthropogenic effects, also it will offer geo-educational opportunities to the general public and to the scientific community, enhancement of Geo-tourism which will be linked easily with the Ancient Egyptian tourism, it will also provide a significant economic benefit to Abu-Roash residential area. Finally, the research recommends that The United Nations Educational, Scientific and Cultural Organizations promote conservation of geological and geo-morphological heritage to list this area for its importance under the umbrella of geo-parks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geo-park" title="geo-park">geo-park</a>, <a href="https://publications.waset.org/abstracts/search?q=geo-sites" title=" geo-sites"> geo-sites</a>, <a href="https://publications.waset.org/abstracts/search?q=Abu-roash" title=" Abu-roash"> Abu-roash</a>, <a href="https://publications.waset.org/abstracts/search?q=archaeological%20sites" title=" archaeological sites"> archaeological sites</a>, <a href="https://publications.waset.org/abstracts/search?q=geo-tourism" title=" geo-tourism"> geo-tourism</a> </p> <a href="https://publications.waset.org/abstracts/76402/assessment-proposal-to-establish-the-first-geo-park-in-egypt-at-abu-roash-area-cairo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76402.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">305</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">743</span> Case Study: Hybrid Mechanically Stabilized Earth Wall System Built on Basal Reinforced Raft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Kaymak%C3%A7%C4%B1">S.

Rather than using a piled foundation, the client was convinced that a ground improvement using a reinforced foundation raft also known as “basal reinforcement” shall work. The retaining structures supporting the truck park area were designed using a hybrid structure made up of the Terramesh® Wall System and MacGrid™ high strength geogrids. The total wall surface area is nearly 2740 sq.m , reaching a maximum height of 13.00 meters. The area is located in the first degree seismic zone of Turkey and the design seismic acceleration is high.

This raises the need of discussing about actions for sustainable tourism that should be linked not only to the economy, but also to the environment and social aspects. The work that is going to be presented is part of a doctoral research project in Sciences undertaken at the Sao Paulo University, Brazil. It aims to analyze whether the monitoring of the tourism sector with a focus on sustainability is applicable or not, through those indicators, put in a case study in the Jalapão State Park (JSP) conservation unit, in the state of Tocantins, Brazil. This is a study of an interdisciplinary nature that had the deductive method as its guide. We concluded that the key points of the sustainable tourism, when analyzed with the focal point in environmental indicators, are an important evaluation and quantification tool of that activity in the study <em>locus. </em>It displayed itself as an adequate tool for monitoring, thus decoding, the main environmental impacts that occur in tourism regions and their intensity, which is made possible through analysis, and has the objective to trace ways to prevent and correct the presented impacts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indicators" title="indicators">indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalap%C3%A3o" title=" Jalapão"> Jalapão</a> </p> <a href="https://publications.waset.org/abstracts/52512/monitoring-of-key-indicators-of-sustainable-tourism-in-the-jalapao-state-parktocantins-a-case-study-of-environmental-indicators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52512.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">331</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">741</span> Geotechnical Characterization of Landslide in Dounia Park, Algiers, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mira%20Filali">Mira Filali</a>, <a href="https://publications.waset.org/abstracts/search?q=Amar%20Nechnech"> Amar Nechnech</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most landslides in Algiers take place in Piacenzian marls of the Sahel (port in Arabic) and cause severe damage to properties and infrastructures. The aim of this paper is to describe the results of experimental as well as theoretical analysis of landslides. In order to understand the process which caused this slope instabilities, the results of geotechnical investigation carried out by the laboratory of construction (LNHC) laboratory in the area of Dounia park were analyzed, including particle size distribution, Atterberg limits, shear strength, odometer and pressuremeter tests. The study shows that the soils exhibited a high capacity to swelling according to index plasticity and clay content. Highs limit liquidity (LL) (53.45%) means that the soils are susceptible to landslides. The stability analysis carried out using finite element method, shows that the slope is stable (Fs > 1) in dry condition and in static state. Despite this results, the stable site could be described as only conditionally stable because slope failure can occur under combined effect of different factors. In fact the safety factor obtained by applying load when the phreatic surface is at ground, less than 1.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=index%20properties" title="index properties">index properties</a>, <a href="https://publications.waset.org/abstracts/search?q=landslides" title=" landslides"> landslides</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20factor" title=" safety factor"> safety factor</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20stability" title=" slope stability"> slope stability</a> </p> <a href="https://publications.waset.org/abstracts/73166/geotechnical-characterization-of-landslide-in-dounia-park-algiers-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73166.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">239</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">740</span> Bond Strength between Concrete and AR-Glass Roving with Variables of Development Length</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jongho%20Park">Jongho Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Taekyun%20Kim"> Taekyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinwoong%20Choi"> Jinwoong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungnam%20Hong"> Sungnam Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun-Kyu%20Park"> Sun-Kyu Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, the climate change is the one of the main problems. This abnormal phenomenon is consisted of the scorching heat, heavy rain and snowfall, and cold wave that will be enlarged abnormal climate change repeatedly. Accordingly, the width of temperature change is increased more and more by abnormal climate, and it is the main factor of cracking in the reinforced concrete. The crack of the reinforced concrete will affect corrosion of steel re-bar which can decrease durability of the structure easily. Hence, the elimination of the durability weakening factor (steel re-bar) is needed. Textile which weaves the carbon, AR-glass and aramid fiber has been studied actively for exchanging the steel re-bar in the Europe for about 15 years because of its good durability. To apply textile as the concrete reinforcement, the bond strength between concrete and textile will be investigated closely. Therefore, in this paper, pull-out test was performed with change of development length of textile. Significant load and stress was increasing at D80.

SynRM for fan usually operates on the constant torque region, at synchronous speed the MTPA control is adopted due to current vector. However, finite element analysis (FEA) program is not sufficient exactly to reflect how the core loss influenced on the current vector. This paper proposed a method to calculate the current vector with consideration of core loss. The precision of current vector by ECM is useful for MTPA control.

In order to produce titanium powders, it is necessary to melt titanium, and generally it is conducted by an induction heating method using Al₂O₃ ceramic crucible. However, since titanium reacts chemically with Al₂O₃, it is difficult to melt titanium by the induction heating method using Al₂O₃ crucible. To avoid this problem, we studied the chemical stability of the various crucibles such as Al₂O₃, MgO, ZrO₂, and Y₂O₃ crucibles to molten titanium. After titanium lumps (Grade 2, O(oxygen)<0.25wt%) were placed in each crucible, they were heated to 1800℃ with a heating rate of 5 ℃/min, held at 1800℃ for 30 min, and finally cooled to room temperature with a cooling rate of 5 ℃/min. All heat treatments were carried out in high purity Ar atmosphere. To evaluate the chemical stability, thermodynamic data such as Ellingham diagram were utilized, and also Vickers hardness test, microstructure analysis, and EPMA quantitative analysis were performed. As a result, Al₂O₃, MgO and ZrO₂ crucibles chemically reacted with molten titanium, but Y₂O₃ crucible rarely reacted with it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium" title="titanium">titanium</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20melting" title=" induction melting"> induction melting</a>, <a href="https://publications.waset.org/abstracts/search?q=crucible" title=" crucible"> crucible</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20stability" title=" chemical stability"> chemical stability</a> </p> <a href="https://publications.waset.org/abstracts/77805/chemical-stability-of-ceramic-crucibles-to-molten-titanium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77805.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">736</span> Approach to Functional Safety-Compliant Design of Electric Power Steering Systems for Commercial Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Chul%20Koag">Hyun Chul Koag</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Sik%20Ahn"> Hyun-Sik Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose a design approach for the safety mechanism of an actuator used in a commercial vehicle’s EPS system. As the number of electric/electronic system in a vehicle increases, the importance of the functional safety has been receiving much attention. EPS(Electric Power Steering) systems for commercial vehicles require large power than passenger vehicles, and hence, dual motor can be applied to get more torque. We show how to formulate the development process for the design of hardware and software of an EPS system using dual motors. A lot of safety mechanisms for the processor, sensors, and memory have been suggested, however, those for actuators have not been fully researched. It is shown by metric analyses that the target ASIL(Automotive Safety Integrated Level) is satisfied in the point of view of hardware of EPS controller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=safety%20mechanism" title="safety mechanism">safety mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20safety" title=" functional safety"> functional safety</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20vehicles" title=" commercial vehicles"> commercial vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20power%20steering" title=" electric power steering"> electric power steering</a> </p> <a href="https://publications.waset.org/abstracts/71842/approach-to-functional-safety-compliant-design-of-electric-power-steering-systems-for-commercial-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71842.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">393</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">735</span> Optimal Sensing Technique for Estimating Stress Distribution of 2-D Steel Frame Structure Using Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun%20Su%20Park">Jun Su Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung%20Kwan%20Oh"> Byung Kwan Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Woo%20Hwang"> Jin Woo Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousok%20Kim"> Yousok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo%20Seon%20Park"> Hyo Seon Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the structural safety, the maximum stress calculated from the stress distribution of a structure is widely used. The stress distribution can be estimated by deformed shape of the structure obtained from measurement. Although the estimation of stress is strongly affected by the location and number of sensing points, most studies have conducted the stress estimation without reasonable basis on sensing plan such as the location and number of sensors. In this paper, an optimal sensing technique for estimating the stress distribution is proposed. This technique proposes the optimal location and number of sensing points for a 2-D frame structure while minimizing the error of stress distribution between analytical model and estimation by cubic smoothing splines using genetic algorithm. To verify the proposed method, the optimal sensor measurement technique is applied to simulation tests on 2-D steel frame structure. The simulation tests are performed under various loading scenarios. Through those tests, the optimal sensing plan for the structure is suggested and verified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20sensing" title=" optimal sensing"> optimal sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=optimizing%20sensor%20placements" title=" optimizing sensor placements"> optimizing sensor placements</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20frame%20structure" title=" steel frame structure"> steel frame structure</a> </p> <a href="https://publications.waset.org/abstracts/25426/optimal-sensing-technique-for-estimating-stress-distribution-of-2-d-steel-frame-structure-using-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25426.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">531</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">734</span> Function Approximation with Radial Basis Function Neural Networks via FIR Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyu%20Chul%20Lee">Kyu Chul Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Hyun%20Yoo"> Sung Hyun Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Choon%20Ki%20Ahn"> Choon Ki Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Myo%20Taeg%20Lim"> Myo Taeg Lim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent experimental evidences have shown that because of a fast convergence and a nice accuracy, neural networks training via extended Kalman filter (EKF) method is widely applied.

In order to overcome this problem in this paper, a new finite impulse response (FIR) filter based learning algorithm is proposed to train radial basis function neural networks (RBFN) for nonlinear function approximation.

Among those techniques, strengthening methodology based on diagonal FRP strips (FRP bracings) has numerous advantages such as feasibility of implementing without interrupting the building under operation, reduction of cost and time, and easy application. Considering the safety of structure and retrofit cost, the most appropriate retrofit solution is needed. Thus, the objective of this study is to suggest pareto-optimal solution for existing building using FRP bracings. To find pareto-optimal solution analysis, NSGA-II is applied. Moreover, the seismic performance of retrofit building is evaluated. The example building is 5-storey, 3-bay RC frames with infill wall. Nonlinear static pushover analyses are performed with FEMA 356. The criterion of performance evaluation is inter-story drift ratio at the performance level IO, LS, CP. Optimal retrofit solutions is obtained for 32 individuals and 200 generations.

How to more accurately evaluate the usage characteristics of public space can help improve its spatial quality. Compared to traditional survey methods, computer vision technology based on deep learning has advantages such as dynamic observation and low cost. This study takes the public space of Shaping Park as an example and, based on deep learning computer vision technology, processes and analyzes the image data of the public space to obtain the spatial usage characteristics and spatiotemporal characteristics of the public space. Research has found that the spontaneous activity time in public spaces is relatively random with a relatively short average activity time, while social activities have a relatively stable activity time with a longer average activity time. Computer vision technology based on deep learning can effectively describe the spatial usage characteristics of the research area, making up for the shortcomings of traditional research methods and providing relevant support for creating a good public space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title="computer vision">computer vision</a>, <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=public%20spaces" title=" public spaces"> public spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=using%20features" title=" using features"> using features</a> </p> <a href="https://publications.waset.org/abstracts/173323/analysis-of-public-space-usage-characteristics-based-on-computer-vision-technology-taking-shaping-park-as-an-example" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173323.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">70</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">731</span> A Study on Relationships between Authenticity of Transactions, Quality of Relationships, and Transaction Performances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chan%20Kwon%20Park">Chan Kwon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Chae-Bogk%20Kim"> Chae-Bogk Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Min%20Park"> Sung-Min Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is a research on the authenticity of transactions between corporations and quality of their relationships and transaction performances. As the factors of authenticity of transactions, honesty, transparency, customer orientation and consistency were selected; as the factors of quality of relationships, trust and commitment were selected, and as the factors of transactions performances, intention of repeat transactions and switching intention were selected, and on these relationships a hypothesis was established, and verification was conducted. First, the factors of the authenticity of transactions positively influenced the factors of quality of relationships. Thus, a higher level of authenticity of transactions can lead to higher level of trust and commitment. Second, the factors of quality of relationships made a positive influence on the intention of repeat transactions, while a negative influence in the switching intention. Third, it showed that trust and commitment as the factors of quality of relationships functioned partly as the parameter between the authenticity of transactions and transaction performances. Finally, it proved that the factors of the authenticity of transactions improved trust and commitment in transactions between corporations and further improved the intention of repeat transactions while they decreased the switching intention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=authenticity%20of%20transactions" title="authenticity of transactions">authenticity of transactions</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a>, <a href="https://publications.waset.org/abstracts/search?q=commitment" title=" commitment"> commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=intention%20of%20repeat%20transactions" title=" intention of repeat transactions"> intention of repeat transactions</a>, <a href="https://publications.waset.org/abstracts/search?q=switching%20intention" title=" switching intention"> switching intention</a> </p> <a href="https://publications.waset.org/abstracts/54024/a-study-on-relationships-between-authenticity-of-transactions-quality-of-relationships-and-transaction-performances" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54024.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">373</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">730</span> Basic Aspects and Ecology of a Group of Capuchin Monkeys (Cebus spp.) (Primates: Cebidae) and Frequency of Contact with Visitor of the State Park Alberto Lofgren, Sao Paulo, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luma%20Vaz">Luma Vaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcio%20Port-Carvalho"> Marcio Port-Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this research was to study the basics aspects of the ecology of a group of capuchin monkeys (Cebus spp.), evaluating the risks that habit and food that is given by the visitors may cause to the people's health and animals welfare, also how to make proposals for mitigation and management guidelines. In order to do that, some aspects of the animal's ecology (such as diet, habitat range and habitat use) and activity patterns were studied. It was also measured the frequency of contact with visitors at the park using protocols for data collection. The behavioral categories of displacement and resting represent more than 80% of total activities, followed by feeding (13%) and others (6%). When compared to the studies in natural environment, the Cebus group studied has a small living area (1.7ha) occupying mostly the PEAL public area. The diversity of items offered by the visitors and the high frequency of contact closer than one meter suggests that using information and education campaigns must be a priority in the public program in PEAL in order to avoid future accidents and diseases transmissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capuchin%20monkeys" title="capuchin monkeys">capuchin monkeys</a>, <a href="https://publications.waset.org/abstracts/search?q=Cebus" title=" Cebus"> Cebus</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20education" title=" environmental education"> environmental education</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20management" title=" wildlife management"> wildlife management</a> </p> <a href="https://publications.waset.org/abstracts/105338/basic-aspects-and-ecology-of-a-group-of-capuchin-monkeys-cebus-spp-primates-cebidae-and-frequency-of-contact-with-visitor-of-the-state-park-alberto-lofgren-sao-paulo-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105338.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">142</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">729</span> Fatigue Evaluation of Link Slab for Continuous Girder-Type Precast Modular Bridges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae-Joon%20Song">Jae-Joon Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang-Yoon%20Lee"> Sang-Yoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Bong-Chul%20Joo"> Bong-Chul Joo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The girder-type precast modular bridge has been developed as a simply supported bridge.

We identified five stages of the psychological process in the development of PD and examined external situations, family dynamics, and psychological experiences at each stage. Method: The client, mother, sister, and husband participated in therapy. Researchers analyzed the transcripts, notes, and video recordings of the therapy sessions. A thematic analysis was used to examine the data and display our findings using a network. Results: The developmental process of PD was as follows: (1) formation of anxiety, (2) sheltered life, (3) crisis, (4) loss of safe haven, and (5) inner breakdown. Conclusion: The family dynamics that developed as a result of coping with external situations in each stage contributed to clients’ psychological experiences. These psychological experiences triggered anxiety, which led to the development of PD. Moreover, this study empirically suggests that family dynamics can be associated with a person’s internal experiences that could lead to PD. Our findings highlight the significance of functional family dynamics and coping patterns when facing difficult external situations or crises. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developmental%20process" title="developmental process">developmental process</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20therapy" title=" family therapy"> family therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=panic%20disorder" title=" panic disorder"> panic disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20dynamics" title=" psychological dynamics"> psychological dynamics</a> </p> <a href="https://publications.waset.org/abstracts/162152/the-developmental-process-of-panic-disorder-focusing-on-the-psychological-dynamics-of-a-family-therapy-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162152.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">95</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">727</span> Community Opinions on Cable Car System Construction at Upper Esaan Wild Animal Adventure Park (Khon Kaen – Udon Thani) in Khao Suan Kwang District, Khon Kaen Province (Khon Kaen Zoo), Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruchirat%20Patanathabutr">Ruchirat Patanathabutr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This applied research has adopted descriptive social science research methodology to interpret, analyze and assess the data and used descriptive analysis to present the research results. The objective of this research is to investigate the behaviors and opinions on the service and construction of cable car system at the Upper Esaan Wild Animal Adventure Park (Khon Kaen – Udon Thani) in Khao Suan Kwang District, Khon Kaen Province (Khon Kaen Zoo) of people in the local and distant communities as well as the service users. The research results have revealed that the main target group is the residents in the upper northeastern region of Thailand, especially those who have resided in the immediate vicinity of the cable car project and in nearby districts for more than 10 years. They are men and women at the age of 20-60 with high school diploma and higher levels of education, working as traders/entrepreneurs, government officers/state enterprise employees, and freelancers/self-employed, with the average monthly income of no more than 30,000 baht. Khon Kaen Zoo should improve its 4 organizational images as a tourist attraction, an animal display enclosure, an educational institution and as a provincial symbol; however, the zoo should mainly be presented as an important tourist attraction. The service should focus on maintaining the service standards in both the animal display area and the ocean park. The attention should also be directed at the types and numbers of animals, service quality, service fee, convenient access and transportation, promotions and the standards of other services. Regarding the community involvement in the cable car system construction project, it is strongly agreed that there should be a cable car service between the animal display area and the ocean park and a round-trip ticket should cost 20 baht, 50 baht or 100 baht, respectively. Khon Kaen Zoo or responsible entity must provide related groups of people, such as people in the local and distant communities as well as the service users, with accurate information about the community management guidelines. This is because the community opinions have showed the uncertainty about the cable car system construction at Khon Kaen Zoo and the 4 principles of management, including planning, organizing, leading and controlling, are indicated as uncertain as there is no statistically significant difference at 0.05. In addition, the social, economic, and environmental impacts of the cable car system construction at Khon Kaen Zoo on the communities must be considered carefully. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20opinion" title="community opinion">community opinion</a>, <a href="https://publications.waset.org/abstracts/search?q=cable%20car%20system" title=" cable car system"> cable car system</a>, <a href="https://publications.waset.org/abstracts/search?q=Khon%20Kaen%20Zoo" title=" Khon Kaen Zoo"> Khon Kaen Zoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Thailand" title=" Thailand"> Thailand</a> </p> <a href="https://publications.waset.org/abstracts/27304/community-opinions-on-cable-car-system-construction-at-upper-esaan-wild-animal-adventure-park-khon-kaen-udon-thani-in-khao-suan-kwang-district-khon-kaen-province-khon-kaen-zoo-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27304.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">360</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">726</span> Rheological Properties of Cellulose/TBAF/DMSO Solutions and Their Application to Fabrication of Cellulose Hydrogel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deokyeong%20Choe">Deokyeong Choe</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Eun%20Nam"> Jae Eun Nam</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Hoon%20Roh"> Young Hoon Roh</a>, <a href="https://publications.waset.org/abstracts/search?q=Chul%20Soo%20Shin"> Chul Soo Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of hydrogels with a high mechanical strength is important for numerous applications of hydrogels. As a material for tough hydrogels, cellulose has attracted much interest. However, cellulose cannot be melted and is very difficult to be dissolved in most solvents. Therefore, its dissolution in tetrabutylammonium fluoride/dimethyl sulfoxide (TBAF/DMSO) solvents has attracted researchers for chemical processing of cellulose. For this reason, studies about rheological properties of cellulose/TBAF/DMSO solution will provide useful information. In this study, viscosities of cellulose solutions prepared using different amounts of cellulose and TBAF in DMSO were measured. As expected, the viscosity of cellulose solution decreased with respect to the increasing volume of DMSO. The most viscose cellulose solution was achieved at a 1:1 mass ratio of cellulose to TBAF regardless of their contents in DMSO. At a 1:1 mass ratio of cellulose to TBAF, the formation of cellulose nanoparticles (467 nm) resulted in a dramatic increase in the viscosity, which led to the fabrication of 3D cellulose hydrogels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellulose" title="cellulose">cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=TBAF%2FDMSO" title=" TBAF/DMSO"> TBAF/DMSO</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogel" title=" hydrogel"> hydrogel</a> </p> <a href="https://publications.waset.org/abstracts/55446/rheological-properties-of-cellulosetbafdmso-solutions-and-their-application-to-fabrication-of-cellulose-hydrogel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55446.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">251</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">725</span> Analysis of Silicon Controlled Rectifier-Based Electrostatic Discharge Protection Circuits with Electrical Characteristics for the 5V Power Clamp</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun-Geol%20Park">Jun-Geol Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung-Il%20Do"> Kyoung-Il Do</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Ju%20Kwon"> Min-Ju Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Hyun%20Park"> Kyung-Hyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Seo%20Koo"> Yong-Seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyzed the SCR (Silicon Controlled Rectifier)-based ESD (Electrostatic Discharge) protection circuits with the turn-on time characteristics. The structures are the LVTSCR (Low Voltage Triggered SCR), the ZTSCR (Zener Triggered SCR) and the PTSCR (P-Substrate Triggered SCR). The three structures are for the 5V power clamp. In general, the structures with the low trigger voltage structure can have the fast turn-on characteristics than other structures. All the ESD protection circuits have the low trigger voltage by using the N+ bridge region of LVTSCR, by using the zener diode structure of ZTSCR, by increasing the trigger current of PTSCR. The simulation for the comparison with the turn-on time was conducted by the Synopsys TCAD simulator. As the simulation results, the LVTSCR has the turn-on time of 2.8 ns, ZTSCR of 2.1 ns and the PTSCR of 2.4 ns. The HBM simulation results, however, show that the PTSCR is the more robust structure of 430K in HBM 8kV standard than 450K of LVTSCR and 495K of ZTSCR. Therefore the PTSCR is the most effective ESD protection circuit for the 5V power clamp. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ESD" title="ESD">ESD</a>, <a href="https://publications.waset.org/abstracts/search?q=SCR" title=" SCR"> SCR</a>, <a href="https://publications.waset.org/abstracts/search?q=turn-on%20time" title=" turn-on time"> turn-on time</a>, <a href="https://publications.waset.org/abstracts/search?q=trigger%20voltage" title=" trigger voltage"> trigger voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20clamp" title=" power clamp"> power clamp</a> </p> <a href="https://publications.waset.org/abstracts/65650/analysis-of-silicon-controlled-rectifier-based-electrostatic-discharge-protection-circuits-with-electrical-characteristics-for-the-5v-power-clamp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65650.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">348</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">724</span> Study of the Microflora of Cedar Forests with Different Degrees of Decline in the National Park Belezma (Batna, Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cherak%20Imen">Cherak Imen</a>, <a href="https://publications.waset.org/abstracts/search?q=Sellami%20Mehdi"> Sellami Mehdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Atlas cedar, Cedrus atlantica, is endemic to the mountains of North Africa. This is one of the most valuable softwood, both economically, ecologically, aesthetically and culturally. In Algeria, the cedar forests currently have worrying symptoms of decline which therefore require special monitoring. Fungal endophytes are involved in various diseases of the Atlas cedar. They attack all organs on which they cause many symptoms. These microflora live in complex interaction with plants. In this study, we identified a total of 09 mycotaxons collected needles Cedarwood at three stations with different degrees of decline (Talmet, Boumerzoug and Tuggurt) in the National Park Belezma (Batna, Algeria). The study conducted on a total of 12 trees were identified 08 mycoendophytes in Talmet station, 04 species in the Boumerzoug station and 03 in Tuggurt station. The total species richness mycoendophytes depending on the types of cedar forests showed that the largest diversity was recorded at the cedar forest healthy, Alternaria is the most common type in all stations. This work should be completed by further detailed studies to identify other endophyte species and better know its interactions with the Atlas cedar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cedrus%20atlantica" title="Cedrus atlantica">Cedrus atlantica</a>, <a href="https://publications.waset.org/abstracts/search?q=endophytic%20fungi" title=" endophytic fungi"> endophytic fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=microflora" title=" microflora"> microflora</a>, <a href="https://publications.waset.org/abstracts/search?q=mycotaxons" title=" mycotaxons"> mycotaxons</a>, <a href="https://publications.waset.org/abstracts/search?q=mycoendophyte" title=" mycoendophyte"> mycoendophyte</a> </p> <a href="https://publications.waset.org/abstracts/31488/study-of-the-microflora-of-cedar-forests-with-different-degrees-of-decline-in-the-national-park-belezma-batna-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31488.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">723</span> A Study on the Reliability Evaluation of a Timer Card for Air Dryer of the Railway Vehicle </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chul%20Su%20Kim">Chul Su Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Ku%20Lee"> Jun Ku Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Won%20Jun%20Lee"> Won Jun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The EMU (electric multiple unit) vehicle timer card is a PCB (printed circuit board) for controlling the air-dryer to remove the moisture of the generated air from the air compressor of the braking device. This card is exposed to the lower part of the railway vehicle, so it is greatly affected by the external environment such as temperature and humidity. The main cause of the failure of this timer card is deterioration of soldering area of the PCB surface due to temperature and humidity. Therefore, in the viewpoint of preventive maintenance, it is important to evaluate the reliability of the timer card and predict the replacement cycle to secure the safety of the air braking device is one of the main devices for driving. In this study, the existing and the improved products were evaluated on the reliability through ALT (accelerated life test). In addition, the acceleration factor by the 'Coffin-Manson' equation was obtained, and the remaining lifetime was compared and examined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20evaluation" title="reliability evaluation">reliability evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=timer%20card" title=" timer card"> timer card</a>, <a href="https://publications.waset.org/abstracts/search?q=Printed%20Circuit%20Board" title=" Printed Circuit Board"> Printed Circuit Board</a>, <a href="https://publications.waset.org/abstracts/search?q=Accelerated%20Life%20Test" title=" Accelerated Life Test"> Accelerated Life Test</a> </p> <a href="https://publications.waset.org/abstracts/69077/a-study-on-the-reliability-evaluation-of-a-timer-card-for-air-dryer-of-the-railway-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69077.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">279</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">722</span> A Study on the Relationship between Nonverbal Communication, Perceived Expertise, Service Quality, and Trust: Focusing on Cosmetic Stores in Korea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Park%20Sung-Min">Park Sung-Min</a>, <a href="https://publications.waset.org/abstracts/search?q=Chan%20Kwon%20Park"> Chan Kwon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Kim%20Chae-Bogk"> Kim Chae-Bogk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to analyze the relationship between nonverbal communication, perceived expertise, service quality, and trust. The study was conducted with clients using cosmetic stores in the Daegu area of Korea. Based on the prior study, the measurement questions are correctly amended and organized in this study. The exploration factor analysis was performed using SPSS 22 for the configured measurement questions. And PLS 2.0 was used to perform a confirmatory factor analysis and path analysis. As a result of the analysis, nonverbal communication has been categorized as physical appearance, kinesics, vocal behavior and proxemics. It has been shown that all of the factors in nonverbal communication have a (+) significant effect on perceived expertise. The degree of impact has been analyzed to influence the perceived expertise in the order in which physical appearance, vocal behavior, kinesics and proxemics. The perceived expertise was analyzed to have a (+) significant effect on the service quality. It has been shown that the service quality has a (+) significant effect on trust. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonverbal%20communication" title="nonverbal communication">nonverbal communication</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20expertise" title=" perceived expertise"> perceived expertise</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20quality" title=" service quality"> service quality</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a> </p> <a href="https://publications.waset.org/abstracts/94170/a-study-on-the-relationship-between-nonverbal-communication-perceived-expertise-service-quality-and-trust-focusing-on-cosmetic-stores-in-korea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">284</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">721</span> Greenland Monitoring Using Vegetation Index: A Case Study of Lal Suhanra National Park</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabia%20Munsaf%20Khan">Rabia Munsaf Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Eshrat%20Fatima"> Eshrat Fatima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The analysis of the spatial extent and temporal change of vegetation cover using remotely sensed data is of critical importance to agricultural sciences. Pakistan, being an agricultural country depends on this resource as it makes 70% of the GDP. The case study is of Lal Suhanra National Park, which is not only the biggest forest reserve of Pakistan but also of Asia. The study is performed using different temporal images of Landsat. Also, the results of Landsat are cross-checked by using Sentinel-2 imagery as it has both higher spectral and spatial resolution. Vegetation can easily be detected using NDVI which is a common and widely used index. It is an important vegetation index, widely applied in research on global environmental and climatic change. The images are then classified to observe the change occurred over 15 years. Vegetation cover maps of 2000 and 2016 are used to generate the map of vegetation change detection for the respective years and to find out the changing pattern of vegetation cover. Also, the NDVI values aided in the detection of percentage decrease in vegetation cover. The study reveals that vegetation cover of the area has decreased significantly during the year 2000 and 2016. <p class="card-text"><strong>Keywords:</strong> <a
