Hence, the surface pressure distribution is critical for optimum design. Though when the model is wide enough on spanwise direction the flow can be regarded as a two-dimensional flow, in actual applications a finite width would normally cause some three-dimensional spillage effects. No research has been found addressed this problem, hence the primary interest of this study is to set up a liable surface pressure distribution on a double ramp with three-dimensional effects. Both numerical and experimental (pressure sensitive paints) are applied to obtain the pressure distribution; the results agree well except that the numerical computation doesn’t capture the Gortler vortices. The pressure variations on the spanwise planes are used to analyse the development of the Gortler vortices and the effects of three-dimensional spillage on the vortices. Results indicate that the three-dimensionl spillage effects not only enhance the developing of the Gortler vortice, but also increase the periodic distance between vortice pairs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spillage%20effects" title="spillage effects">spillage effects</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20sensitive%20paints" title=" pressure sensitive paints"> pressure sensitive paints</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersonic" title=" hypersonic"> hypersonic</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20ramp" title=" double ramp"> double ramp</a> </p> <a href="https://publications.waset.org/abstracts/59201/three-dimensional-spillage-effects-on-the-pressure-distribution-of-a-double-ramp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59201.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">330</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> The Intense Fascination of Ancient Egypt: A Cross-Cultural Phenomenological Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Andrew%20McCoy">Patrick Andrew McCoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The intense fascination with ancient Egypt has persisted for thousands of years and across cultures globally, known popularly as Egyptomania,’ ‘Tutmania,’ ‘Mummymania,’ and ‘Orientalism. A review of the literature indicates psychological themes for its behavior are curiosity, escapism, existentialism, religiosity and spirituality, and cultural, racial, and ethnic identity. A mixed-methods study is initiated with established tools to explore these themes and discover additional motivators. Objectives: The purpose of the study is to explore the themes underlying the intense fascination of ancient Egypt. The abstract themes of the fascination of ancient Egypt are cross-cultural phenomena that motivate people in their interactions with other cultures. These interactions have both been beneficial and combative. Methodology: A mixed methods research study is designed where quantitative (QUAN) survey of participants’ strong fascination with ancient Egypt, within psychological themes derived from a review of the literature. The qualitative (QUAL) survey consists of open-ended questions to explore participants’ exposure to ancient Egypt that may have influenced their fascination and their behaviors resulting from the phenomenon. The themes are explored in QUAN data and QUAL data to discover what themes are established and inferred the psychological motivations of the phenomenon. Main Contributions: This study will provide more information on several scientific disciplines, including psychology, anthropology, Egyptology, and tourism. This study seeks to benefit the tourism industry for not only in Egypt but hopefully with generalizability of cultural tourist industries in other countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-cultural%20psychology" title="cross-cultural psychology">cross-cultural psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20psychology" title=" international psychology"> international psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed-methods" title=" mixed-methods"> mixed-methods</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=ancient%20Egypt" title=" ancient Egypt"> ancient Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=phenomenology" title=" phenomenology"> phenomenology</a>, <a href="https://publications.waset.org/abstracts/search?q=escapism" title=" escapism"> escapism</a>, <a href="https://publications.waset.org/abstracts/search?q=curiosity" title=" curiosity"> curiosity</a>, <a href="https://publications.waset.org/abstracts/search?q=existentialism" title=" existentialism"> existentialism</a>, <a href="https://publications.waset.org/abstracts/search?q=religiosity" title=" religiosity"> religiosity</a>, <a href="https://publications.waset.org/abstracts/search?q=spirituality" title=" spirituality"> spirituality</a> </p> <a href="https://publications.waset.org/abstracts/153623/the-intense-fascination-of-ancient-egypt-a-cross-cultural-phenomenological-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153623.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Methods Used to Perform Requirements Elicitation for FinTech Application Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Pengcheng">Zhao Pengcheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yin%20Siyuan"> Yin Siyuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fintech is the new hot topic of the 21st century, a discipline that combines financial theory with computer modelling. It can provide both digital analysis methods for investment banks and investment decisions for users. Given the variety of services available, it is necessary to provide a superior method of requirements elicitation to ensure that users' needs are addressed in the software development process. The accuracy of traditional software requirements elicitation methods is not sufficient, so this study attempts to use a multi-perspective based requirements heuristic framework. Methods such as interview and questionnaire combination, card sorting, and model driven are proposed. The collection results from PCA show that the new methods can better help with requirements elicitation. However, the method has some limitations and, there are some efficiency issues. However, the research in this paper provides a good theoretical extension that can provide researchers with some new research methods and perspectives viewpoints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=requirement%20elicitation" title="requirement elicitation">requirement elicitation</a>, <a href="https://publications.waset.org/abstracts/search?q=FinTech" title=" FinTech"> FinTech</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20application" title=" mobile application"> mobile application</a>, <a href="https://publications.waset.org/abstracts/search?q=survey" title=" survey"> survey</a>, <a href="https://publications.waset.org/abstracts/search?q=interview" title=" interview"> interview</a>, <a href="https://publications.waset.org/abstracts/search?q=model-driven" title=" model-driven"> model-driven</a> </p> <a href="https://publications.waset.org/abstracts/158707/methods-used-to-perform-requirements-elicitation-for-fintech-application-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158707.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">103</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> BingleSeq: A User-Friendly R Package for Single-Cell RNA-Seq Data Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Quan%20Gu">Quan Gu</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20%20Dimitrov"> Daniel Dimitrov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> BingleSeq was developed as a shiny-based, intuitive, and comprehensive application that enables the analysis of single-Cell RNA-Sequencing count data.

In Kenya the disease status of SHUV in cattle has never been established. It is a zoonotic virus and even though studies have been carried out as early as the 1960s, little research has been published and SHUV is still not a well-recognised Orthobunyavirus. One hundred serum samples were collected from healthy cattle in Kenya and tested for antibodies against SHUV by a serum neutralization assay. All antibody titre values were greater than 1:160, with most of the samples greater than 1:320. Of the samples tested, 87 % had titres greater than 1:320, 12% had a titre of 1:320 and 2% had a titre of 1:160. Samples were classified as positive if the antibody titre was ≥ 1:10 and negative if < 1:10. This study suggests that cattle are exposed commonly to SHUV, which may be endemic in Kenya. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shuni%20virus" title="Shuni virus">Shuni virus</a>, <a href="https://publications.waset.org/abstracts/search?q=Orthobunyavuruses" title=" Orthobunyavuruses"> Orthobunyavuruses</a>, <a href="https://publications.waset.org/abstracts/search?q=serum%20neutralization%20test" title=" serum neutralization test"> serum neutralization test</a>, <a href="https://publications.waset.org/abstracts/search?q=cell-culture" title=" cell-culture"> cell-culture</a> </p> <a href="https://publications.waset.org/abstracts/161488/the-detection-of-antibodies-against-shuni-virus-in-cattle-from-western-kenya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161488.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">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Displaying of GnRH Peptides on Bacteriophage T7 and Its Immunogenicity in Mice Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hai%20Xu">Hai Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yiwei%20Wang"> Yiwei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xi%20Bao"> Xi Bao</a>, <a href="https://publications.waset.org/abstracts/search?q=Bihua%20Deng"> Bihua Deng</a>, <a href="https://publications.waset.org/abstracts/search?q=Pengcheng%20Li"> Pengcheng Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Lu"> Yu Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> T7 phage could be used as a perfect vector for peptides expression and haptens presentation. T7-3GnRH recombinant phage was constructed by inserting three copies of Gonadotrophin Releasing Hormone (GnRH) gene into the multiple cloning site of T7 Select 415-1b phage genome. The positive T7-3GnRH phage was selected by using polymerase chain reaction amplification, and the p10B-3GnRH fusion protein was verified by SDS-PAGE and Western-blotting assay. T7-3GnRH vaccine was made and immunized with 10<sup>10</sup> pfu in 0.2 ml per dose in mice. Blood samples were collected at an interval in weeks, and anti-GnRH antibody and testosterone concentrations were detected by ELISA and radioimmunoassay, respectively. The results show that T7-3GnRH phage particles confer a high immunogenicity to the GnRH-derived epitope. Moreover, the T7-3GnRH vaccine induced higher level of anti-GnRH antibody than ImproVac<sup>®</sup>. However, the testosterone concentrations in both immunized groups were at a similar level, and the testis developments were significantly inhibited compared to controls. These findings demonstrated that the anti-GnRH antibody could neutralize the endogenous GnRH to down regulate testosterone level and limit testis development, highlighting the potential value of T7-3GnRH in the immunocastration vaccine research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gonadotrophin%20Releasing%20Hormone%20%28GnRH%29" title="Gonadotrophin Releasing Hormone (GnRH)">Gonadotrophin Releasing Hormone (GnRH)</a>, <a href="https://publications.waset.org/abstracts/search?q=Immunocastration" title=" Immunocastration"> Immunocastration</a>, <a href="https://publications.waset.org/abstracts/search?q=T7%20phage" title=" T7 phage"> T7 phage</a>, <a href="https://publications.waset.org/abstracts/search?q=Phage%20vaccine" title=" Phage vaccine"> Phage vaccine</a> </p> <a href="https://publications.waset.org/abstracts/70756/displaying-of-gnrh-peptides-on-bacteriophage-t7-and-its-immunogenicity-in-mice-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70756.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">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Feasibility of Ground Alkali-Active Sandstone Powder for Use in Concrete as Mineral Admixture </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xia%20Chen">Xia Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hua-Quan%20Yang"> Hua-Quan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shi-Hua%20Zhou"> Shi-Hua Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alkali-active sandstone aggregate was ground by vertical and ball mill into particles with residue over 45 μm less than 12%, and investigations have been launched on particles distribution and characterization of ground sandstone powder, fluidity, heat of hydration, strength as well as hydration products morphology of pastes with incorporation of ground sandstone powder.

Dc or AC voltage is applied to the induction motor using the SVPWM through the inverter. Then stator resistance, stator leakage inductance, rotor resistance, rotor leakage inductance and mutual inductance are obtained according to the signal response. The discrete Fourier transform (DFT) is used to deal with the noise and harmonic. The impact on parameter identification caused by delays in the inverter switch tube, tube voltage drop and dead-time is avoided by effective compensation measures. Finally, the parameter identification experiment is conducted based on the vector inverter which using TMS320F2808 DSP as the core processor and results show that the strategy is verified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vector%20inverter" title="vector inverter">vector inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20identification" title=" parameter identification"> parameter identification</a>, <a href="https://publications.waset.org/abstracts/search?q=SVPWM%3B%20DFT" title=" SVPWM; DFT"> SVPWM; DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=dead-time%20compensation" title=" dead-time compensation"> dead-time compensation</a> </p> <a href="https://publications.waset.org/abstracts/58286/an-improved-parameter-identification-method-for-three-phase-induction-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58286.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">461</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> High Efficiency Electrolyte Lithium Battery and RF Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wei%20Quan">Wei Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Chao"> Liu Chao</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20N.%20Afsar"> Mohammed N.

This innovative solid polymer electrolyte which is highly ionic conductive (10-3 S/cm at room temperature) from -40 oC to +150 oC and can be used in any battery application. Such polymer exhibits properties more like a ceramic rather than polymer. The various applied measurement methods produced accurate dielectric results for comprehensive analysis of electrochemical properties and ion transportation mechanism of this newly invented polymer electrolyte. Two techniques and instruments employing air gap measurement by capacitance bridge and inwave guide measurement by vector network analyzer are applied to measure the complex dielectric spectra. The complex dielectric spectra are used to determine the complex alternating current electrical conductivity and thus the ionic conductivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20electrolyte" title="polymer electrolyte">polymer electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20permittivity" title=" dielectric permittivity"> dielectric permittivity</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20battery" title=" lithium battery"> lithium battery</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20relaxation" title=" ionic relaxation"> ionic relaxation</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20measurement" title=" microwave measurement"> microwave measurement</a> </p> <a href="https://publications.waset.org/abstracts/22483/high-efficiency-electrolyte-lithium-battery-and-rf-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22483.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">478</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> BTG-BIBA: A Flexibility-Enhanced Biba Model Using BTG Strategies for Operating System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gang%20Liu">Gang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Can%20Wang"> Can Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Runnan%20Zhang"> Runnan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Quan%20Wang"> Quan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huimin%20Song"> Huimin Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaomin%20Ji"> Shaomin Ji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biba model can protect information integrity but might deny various non-malicious access requests of the subjects, thereby decreasing the availability in the system.

Traditionally, confidential data of a business is stored in computers located within the premise of the business. Therefore, a lot of business capital is put towards maintaining computing resources and hiring IT teams to manage them. The advent of cloud computing changes everything. Instead of purchasing and managing their infrastructure, many businesses have started to shift towards working with the cloud with the help of a cloud service provider (CSP), leading to cost savings. However, it also introduces security risks. This research paper focuses on the security risks that arise during data migration and user authentication in cloud computing. To overcome this problem, this paper provides a comprehensive framework that includes Transport Layer Security (TLS), user authentication, security tokens and multi-level data encryption. This framework aims to prevent authorized access to cloud resources and data leakage, ensuring the confidentiality of sensitive information. This framework can be used by cloud service providers to strengthen the security of their cloud and instil confidence in their users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cloud%20computing" title="Cloud computing">Cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=Cloud%20security" title=" Cloud security"> Cloud security</a>, <a href="https://publications.waset.org/abstracts/search?q=Cloud%20security%20issues" title=" Cloud security issues"> Cloud security issues</a>, <a href="https://publications.waset.org/abstracts/search?q=Cloud%20security%20framework" title=" Cloud security framework"> Cloud security framework</a> </p> <a href="https://publications.waset.org/abstracts/168890/a-comprehensive-framework-to-ensure-data-security-in-cloud-computing-analysis-solutions-and-approaches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Did Chilling Injury of Rice Decrease under Climate Warming?

In this study, a case study in Northeast China was presented to investigate whether the frequencies of chilling injury declined as a result of climate change, in comprehensive consideration of the potential effects from autonomous adaptation of rice production in response to climate change, such as shifts in cultivation timing and rice cultivars. It was found that frequency of total chilling injury (either delayed-growth type or sterile-type in a year) decreased but only to a limit extent in the context of climate change, mainly owing to a pronounced decrease in frequency of the delayed-growth chilling injury, while there was no overwhelming decreasing tendency for frequency of the sterile-type chilling injury, rather, it even increased considerably for some regions. If changes in cultivars had not occurred, risks of chilling injury of both types would have been much lower, specifically for the sterile-type chilling injury for avoiding deterioration in chilling sensitivity of rice cultivars. In addition, earlier planting helped lower the risk of chilling injury but still can not overweight the effects of introduction of new cultivars. It was concluded that risks of chilling injury in rice would not necessarily decrease as a result of climate change, considering the accompanying adaptation process may increase the chilling sensitivity of rice production system in a warmer climate conditions, and thus precautions should still be taken. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chilling%20injury" title="chilling injury">chilling injury</a>, <a href="https://publications.waset.org/abstracts/search?q=rice" title=" rice"> rice</a>, <a href="https://publications.waset.org/abstracts/search?q=CERES-rice%20model" title=" CERES-rice model"> CERES-rice model</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20warming" title=" climate warming"> climate warming</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20east%20China" title=" North east China"> North east China</a> </p> <a href="https://publications.waset.org/abstracts/29031/did-chilling-injury-of-rice-decrease-under-climate-warming-a-case-study-in-northeast-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29031.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">334</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Electrolytic Capacitor-Less Transformer-Less AC-DC LED Driver with Current Ripple Canceller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasunori%20Kobori">Yasunori Kobori</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Quan"> Li Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu%20Wu"> Shu Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nizam%20Mohyar"> Nizam Mohyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zachary%20Nosker"> Zachary Nosker</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobukazu%20Tsukiji"> Nobukazu Tsukiji</a>, <a href="https://publications.waset.org/abstracts/search?q=Nobukazu%20Takai"> Nobukazu Takai</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruo%20Kobayashi"> Haruo Kobayashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an electrolytic capacitor-less transformer-less AC-DC LED driver with a current ripple canceller.

A detailed urban growth boundary is a prerequisite for urban renewal and management. This study takes Shenyang City, China, as the study area and evaluates the spatial distribution of urban spatial suitability in the study area from the perspective of spatial constraints-suitability using multi-source data and simulates the future rigid and elastic growth boundaries of the city in the study area using the CA-Markov model. The results show that (1) the suitable construction area and moderate construction area in the study area account for 8.76% and 19.01% of the total area, respectively, and the suitable construction area and moderate construction area show a trend of distribution from the urban centre to the periphery, mainly in Shenhe District, the southern part of Heping District, the western part of Dongling District, and the central part of Dadong District; (2) the area of expansion of construction land in the study area in the period of 2023-2030 is 153274.6977hm2, accounting for 44.39% of the total area of the study area; (3) the rigid boundary of the study area occupies an area of 153274.6977 hm2, accounting for 44.39% of the total area of the study area, and the elastic boundary of the study area contains an area of 75362.61 hm2, accounting for 21.69% of the total area of the study area.

The findings are as follows: In general, the information quality of CSR significantly influences individual investors’ perception on investment risks. Furthermore, certification on CSR can help reinforce such perceptions. The higher the reporting quality of CSR is, accompanied by the certification by an independent third party, the more likely individual investors recognize the responsibilities. The research also found that the perception on CSR not only plays a role of intermediation between information quality about CSR and investors’ perception on investment risk but also intermediates the certification of CSR reports and individual investors’ judgment on investment risks. The main contributions of the research are in two folds. The first is that it supplements the research on CSR from the perspective of investors’ perceptions.

NVM applies the technique of Sustainable Mining by Drilling (SMD). The SMD method is used to mine stranded, steeply dipping ore veins, which are too small or isolated to mine economically using conventional methods since the dilution is minimized. This novel mining technique uses drilling rigs to extract the ore through directional drilling surgically. This paper is focusing on utilizing the run of the mine tailings and Portland cement as backfill material to support the hanging wall for providing safe mine operation. Cemented paste backfill (CPB) is designed by mixing waste tailings, water, and cement of the precise percentage for optimal outcomes. It is a non-homogenous material that contains 70-85% solids. Usually, a hydraulic binder is added to the mixture to increase the strength of the CPB. The binder fraction mostly accounts for 2–10% of the total weight. In the mining industry, CPB has been improved and expanded gradually because it provides safety and support for the mines. Furthermore, CPB helps manage the waste tailings in an economical method and plays a significant role in environmental protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=backfilling" title="backfilling">backfilling</a>, <a href="https://publications.waset.org/abstracts/search?q=cement%20backfill" title=" cement backfill"> cement backfill</a>, <a href="https://publications.waset.org/abstracts/search?q=tailings" title=" tailings"> tailings</a>, <a href="https://publications.waset.org/abstracts/search?q=Portland%20cement" title=" Portland cement"> Portland cement</a> </p> <a href="https://publications.waset.org/abstracts/125089/assessment-for-the-backfill-using-the-run-of-the-mine-tailings-and-portland-cement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125089.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">138</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">22</span> Detailed Depositional Resolutions in Upper Miocene Sands of HT-3X Well, Nam Con Son Basin, Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vo%20Thi%20Hai%20Quan">Vo Thi Hai Quan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nam Con Son sedimentary basin is one of the very important oil and gas basins in offshore Vietnam. Hai Thach field of block 05-2 contains mostly gas accumulations in fine-grained, sand/mud-rich turbidite system, which was deposited in a turbidite channel and fan environment. Major Upper Miocene reservoir of HT-3X lies above a well-developed unconformity. The main objectives of this study are to reconstruct depositional environment and to assess the reservoir quality using data from 14 meters of core samples and digital wireline data of the well HT-3X. The wireline log and core data showed that the vertical sequences of representative facies of the well mainly range from Tb to Te divisions of Bouma sequences with predominance of Tb and Tc compared to Td and Te divisions. Sediments in this well were deposited in a submarine fan association with very fine to fine-grained, homogeneous sandstones that have high porosity and permeability, high- density turbidity currents with longer transport route from the sediment source to the basin, indicating good quality of reservoir. Sediments are comprised mainly of the following sedimentary structures: massive, laminated sandstones, convoluted bedding, laminated ripples, cross-laminated ripples, deformed sandstones, contorted bedding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hai%20Thach%20field" title="Hai Thach field">Hai Thach field</a>, <a href="https://publications.waset.org/abstracts/search?q=Miocene%20sand" title=" Miocene sand"> Miocene sand</a>, <a href="https://publications.waset.org/abstracts/search?q=turbidite" title=" turbidite"> turbidite</a>, <a href="https://publications.waset.org/abstracts/search?q=wireline%20data" title=" wireline data"> wireline data</a> </p> <a href="https://publications.waset.org/abstracts/69815/detailed-depositional-resolutions-in-upper-miocene-sands-of-ht-3x-well-nam-con-son-basin-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69815.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">292</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">21</span> Online Pose Estimation and Tracking Approach with Siamese Region Proposal Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Fang">Cheng Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lingwei%20Quan"> Lingwei Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Cunyue%20Lu"> Cunyue Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human pose estimation and tracking are to accurately identify and locate the positions of human joints in the video. It is a computer vision task which is of great significance for human motion recognition, behavior understanding and scene analysis. There has been remarkable progress on human pose estimation in recent years. However, more researches are needed for human pose tracking especially for online tracking. In this paper, a framework, called PoseSRPN, is proposed for online single-person pose estimation and tracking. We use Siamese network attaching a pose estimation branch to incorporate Single-person Pose Tracking (SPT) and Visual Object Tracking (VOT) into one framework. The pose estimation branch has a simple network structure that replaces the complex upsampling and convolution network structure with deconvolution. By augmenting the loss of fully convolutional Siamese network with the pose estimation task, pose estimation and tracking can be trained in one stage. Once trained, PoseSRPN only relies on a single bounding box initialization and producing human joints location. The experimental results show that while maintaining the good accuracy of pose estimation on COCO and PoseTrack datasets, the proposed method achieves a speed of 59 frame/s, which is superior to other pose tracking frameworks. <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=pose%20estimation" title=" pose estimation"> pose estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=pose%20tracking" title=" pose tracking"> pose tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=Siamese%20network" title=" Siamese network"> Siamese network</a> </p> <a href="https://publications.waset.org/abstracts/112839/online-pose-estimation-and-tracking-approach-with-siamese-region-proposal-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112839.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">153</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">20</span> Kaolinite-Assisted Microencapsulation of Octodecane for Thermal Energy Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ting%20Pan">Ting Pan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiacheng%20Wang"> Jiacheng Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Pengcheng%20Lin"> Pengcheng Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Chen"> Ying Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Songping%20Mo"> Songping Mo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phase change materials (PCMs) are widely used in latent heat thermal energy storage because of their good properties such as high energy storage density and constant heat-storage/release temperature. Microencapsulation techniques can prevent PCMs from leaking during the liquid-solid phase transition and enhance thermal properties. This technique has been widely applied in architectural materials, thermo-regulated textiles, aerospace fields, etc. One of the most important processes during the synthesis of microcapsules is to form a stable emulsion of the PCM core and reactant solution for the formation of the shell of the microcapsules. The use of surfactants is usually necessary for the formation of a stable emulsion system because of the difference in hydrophilia/lipophilicity of the PCM and the solvent. Unfortunately, the use of surfactants may cause pollution to the environment. In this study, modified kaolinite was used as an emulsion stabilizer for the microencapsulation of octodecane as PCM. Microcapsules were synthesized by phase inversion emulsification method, and the shell of polymethyl methacrylate (PMMA) was formed through free radical polymerization. The morphologies, crystalloid phase, and crystallization properties of microcapsules were investigated using scanning electron microscopy (SEM), X-ray diffractometer (XRD), and Fourier transforms infrared spectrometer (FTIR). The thermal properties and thermal stability were investigated by a differential scanning calorimeter (DSC) and a thermogravimetric analyzer (TG). The FT-IR, XRD results showed that the octodecane was well encapsulated in the PMMA shell. The SEM results showed that the microcapsules were spheres with an average size of about 50-100nm. The DSC results indicated that the latent heat of the microcapsules was 152.64kJ/kg and 164.23kJ/kg. The TG results confirmed that the microcapsules had good thermal stability due to the PMMA shell. Based on the results, it can be concluded that the modified kaolinite can be used as an emulsifier for the synthesis of PCM microcapsules, which is valid for reducing part of the possible pollution caused by the utilization of surfactants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kaolinite" title="kaolinite">kaolinite</a>, <a href="https://publications.waset.org/abstracts/search?q=microencapsulation" title=" microencapsulation"> microencapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=PCM" title=" PCM"> PCM</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20energy%20storage" title=" thermal energy storage"> thermal energy storage</a> </p> <a href="https://publications.waset.org/abstracts/120077/kaolinite-assisted-microencapsulation-of-octodecane-for-thermal-energy-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120077.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> The Effects of Drying Technology on Rehydration Time and Quality of Mung Bean Vermicelli</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20P.%20Tien">N.

The preparation process involves several steps, including drying, which affects the structure and quality of the vermicelli. This study aims to examine the effects of different drying technologies on the rehydration time and quality of mung bean vermicelli. Three drying technologies, namely hot air drying, microwave continuous drying, and microwave vacuum drying, were used for the drying process. The vermicelli strands were dried at 45°C for 12h in a hot air dryer, at 70 Hz of conveyor belt speed inverter in a microwave continuous dryer, and at 30 W.g⁻¹ of microwave power density in a microwave vacuum dryer. The results showed that mung bean vermicelli dried using hot air drying had the longest rehydration time of 12.69 minutes. On the other hand, vermicelli dried through microwave continuous drying and microwave vacuum drying had shorter rehydration times of 2.79 minutes and 2.14 minutes, respectively. Microwave vacuum drying also resulted in larger porosity, higher water absorption, and cooking loss. The tensile strength and elasticity of vermicelli dried using hot air drying were higher compared to microwave drying technologies. The sensory evaluation did not reveal significant differences in most attributes among the vermicelli treatments. Overall, microwave drying technology proved to be effective in reducing rehydration time and producing good-quality mung bean vermicelli. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mung%20bean%20vermicelli" title="mung bean vermicelli">mung bean vermicelli</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20air" title=" hot air"> hot air</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20continuous" title=" microwave continuous"> microwave continuous</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20vacuum" title=" microwave vacuum"> microwave vacuum</a> </p> <a href="https://publications.waset.org/abstracts/170532/the-effects-of-drying-technology-on-rehydration-time-and-quality-of-mung-bean-vermicelli" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170532.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">79</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">18</span> Study on Resource Allocation of Cloud Operating System Based on Multi-Tenant Data Resource Sharing Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lin%20Yunuo">Lin Yunuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Seow%20Xing%20Quan"> Seow Xing Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Burra%20Venkata%20Durga%20Kumar"> Burra Venkata Durga Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this modern era, the cloud operating system is the world trend applied in various industries such as business, healthy, etc. In order to deal with the large capacity of requirements in cloud computing, research come up with multi-tenant cloud computing to maximize the benefits of server providers and clients. However, there are still issues in multi-tenant cloud computing especially regarding resource allocation. Issues such as inefficient resource utilization, large latency, lack of scalability and elasticity and poor data isolation had caused inefficient resource allocation in multi-tenant cloud computing. Without a doubt, these issues prevent multitenancy reaches its best condition. In fact, there are multiple studies conducted to determine the optimal resource allocation to solve these problems these days. This article will briefly introduce the cloud operating system, Multi-tenant cloud computing and resource allocation in cloud computing. It then discusses resource allocation in multi-tenant cloud computing and the current challenges it faces. According to the issue ‘ineffective resource utilization’, we will discuss an efficient dynamic scheduling technique for multitenancy, namely Multi-tenant Dynamic Resource Scheduling Model (MTDRSM).

In this study, a track ice-making test rig was constructed to verify the accuracy of the established ice track heat transfer model. The different meteorological conditions on the variations in the heat transfer characteristics of the ice surface, ice temperature, and evaporation temperature with or without Terrain Weather Protection System (TWPS) were investigated, and the influence of the TWPS with and without low emissivity materials on these indexes was also compared. In addition, the influence of different pipe spacing and diameters of refrigeration pipe on the heat transfer resistance of the track is also analyzed. The results showed that compared with the ice track without sunshade facilities, TWPS could reduce the heat transfer between ice surface and air by 17.6% in the transition season, and TWPS with low emissivity material could reduce the heat transfer by 37%. The thermal resistance of the ice track decreased by 8.9×10⁻⁴ m²·°C/W, and the refrigerant evaporation temperature increased by 0.25 °C when the cooling pipes spacing decreased by every 10 mm. The thermal resistance decreased by 1.46×10⁻³ m²·°C/W, and the refrigerant evaporation temperature increased by 0.3 °C when the pipe diameter increased by one nominal diameter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bobsleigh%2Fskeleton%20ice%20track" title="bobsleigh/skeleton ice track">bobsleigh/skeleton ice track</a>, <a href="https://publications.waset.org/abstracts/search?q=calculation%20model" title=" calculation model"> calculation model</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer%20characteristics" title=" heat transfer characteristics"> heat transfer characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigeration" title=" refrigeration"> refrigeration</a> </p> <a href="https://publications.waset.org/abstracts/165291/analysis-of-heat-transfer-and-energy-saving-characteristics-for-bobsleighskeleton-ice-track" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165291.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">110</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">16</span> MXene Quantum Dots Decorated Double-Shelled Ceo₂ Hollow Spheres for Efficient Electrocatalytic Nitrogen Oxidation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Quan%20Li">Quan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongcai%20Shen"> Dongcai Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhengting%20Xiao"> Zhengting Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Liu%20Mingrui%20Wu"> Xin Liu Mingrui Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Licheng%20Liu"> Licheng Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Qin%20Li"> Qin Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Xianguo%20Li"> Xianguo Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Wentai%20Wang"> Wentai Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Direct electrocatalytic nitrogen oxidation (NOR) provides a promising alternative strategy for synthesizing high-value-added nitric acid from widespread N₂, which overcomes the disadvantages of the Haber-Bosch-Ostwald process. However, the NOR process suffers from the limitation of high N≡N bonding energy (941 kJ mol− ¹), sluggish kinetics, low efficiency and yield. It is a prerequisite to develop more efficient electrocatalysts for NOR. Herein, we synthesized double-shelled CeO₂ hollow spheres (D-CeO₂) and further modified with Ti₃C₂ MXene quantum dots (MQDs) for electrocatalytic N₂ oxidation, which exhibited a NO₃− yield of 71.25 μg h− ¹ mgcat− ¹ and FE of 31.80% at 1.7 V. The unique quantum size effect and abundant edge active sites lead to a more effective capture of nitrogen. Moreover, the double-shelled hollow structure is favorable for N₂ fixation and gathers intermediate products in the interlayer of the core-shell. The in-situ infrared Fourier transform spectroscopy confirmed the formation of *NO and NO₃− species during the NOR reaction, and the kinetics and possible pathways of NOR were calculated by density functional theory (DFT). In addition, a Zn-N₂ reaction device was assembled with D-CeO₂/MQDs as anode and Zn plate as cathode, obtaining an extremely high NO₃− yield of 104.57 μg h− ¹ mgcat− ¹ at 1 mA cm− ². <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocatalytic%20N%E2%82%82%20oxidation" title="electrocatalytic N₂ oxidation">electrocatalytic N₂ oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate%20production" title=" nitrate production"> nitrate production</a>, <a href="https://publications.waset.org/abstracts/search?q=CeO%E2%82%82" title=" CeO₂"> CeO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=MXene%20quantum%20dots" title=" MXene quantum dots"> MXene quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=double-shelled%20hollow%20spheres" title=" double-shelled hollow spheres"> double-shelled hollow spheres</a> </p> <a href="https://publications.waset.org/abstracts/185272/mxene-quantum-dots-decorated-double-shelled-ceo2-hollow-spheres-for-efficient-electrocatalytic-nitrogen-oxidation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185272.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">69</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">15</span> Phenolic Compounds and Antioxidant Capacity of Tuckeroo (Cupaniopsis anacardioides) Fruits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ngoc%20Minh%20Quynh%20Pham">Ngoc Minh Quynh Pham</a>, <a href="https://publications.waset.org/abstracts/search?q=Quan%20V.%20Vuong"> Quan V.

Its fruits have been eaten by birds; however there is no information on phytochemical and antioxidant capacity of these fruits. This study aimed to determine the phenolic compounds (TPC), flavonoids (TFC), proanthocyanidins (TPro) and antioxidant capacity in the whole or different parts of tuckeroo fruit including skin, flesh and seed. Whole and partly tuckeroo fruits were collected and immediately freeze dried to constant weight and then ground to small particle sizes (<1mm mesh). Samples were extracted in 50% methanol using an ultrasonic bath set at temperature 40 °C for 30 minutes. TPC, TFC, TPro and antioxidant capacity were measured by spectrophotometric analysis. The results showed that the whole fruits contained 106.23 mg GAE/g of TPC, 67.67 mg CAE/g of TFC and 56.74 mg CAE/g of TPro. These fruits also possessed high antioxidant capacity (DPPH: 263.78 mg TroE/g, ABTS: 346.98 mg TroE/g, CUPRAC: 370.12 mg TroE/g and FRAP: 176.30 mg TroE/g), revealing that these fruits are rich source of antioxidants. The results also showed that distribution of the antioxidants was varied in different parts of the fruits. Skin had the highest levels of TPC, TFC, and TPro as well as antioxidant properties, followed by the seed and flesh had the lowest levels of phenolic compounds and antioxidant capacity. Of note, levels of phenolic compounds and antioxidant capacity of the skin were significantly higher than those of the whole fruits. Therefore, the skin of tuckeroo fruits is recommended as a starting material for extraction and purification of phenolic compounds as potential antioxidants for further utilisation in the food and pharmaceutical industries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20capacity" title="antioxidant capacity">antioxidant capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=Cupaniopsis%20anacardioides" title=" Cupaniopsis anacardioides"> Cupaniopsis anacardioides</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=tuckeroo%20fruit" title=" tuckeroo fruit"> tuckeroo fruit</a> </p> <a href="https://publications.waset.org/abstracts/54949/phenolic-compounds-and-antioxidant-capacity-of-tuckeroo-cupaniopsis-anacardioides-fruits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54949.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">399</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">14</span> Determination of the Stability of Haloperidol Tablets and Phenytoin Capsules Stored in the Inpatient Dispensary System (Swisslog) by the Respective HPLC and Raman Spectroscopy Assay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carol%20Yue-En%20Ong">Carol Yue-En Ong</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelina%20Hui-Min%20Tan"> Angelina Hui-Min Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Quan%20Liu"> Quan Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Chi-Lui%20Ho"> Paul Chi-Lui Ho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A public general hospital in Singapore has recently implemented an automated unit-dose machine in their inpatient dispensary, Swisslog, with the objective of reducing human error and improving patient safety. However, a concern in stability arises as tablets are removed from their original packaging (bottled loose tablets/capsules) and are repackaged into individual, clear plastic wrappers as unit doses in the system. Drugs that are light-sensitive and hygroscopic would be more susceptible to degradation as the wrapper does not offer full protection. Hence, this study was carried out to study the stability of haloperidol tablets and phenytoin capsules that are light-sensitive and hygroscopic respectively. Validated HPLC-UV assays were first established for quantification of these two compounds. The medications involved were put in the Swisslog and sampled every week for one month. The collected data was analysed and showed no degradation over time. This study also explored an alternative approach for drug stability determination-Raman spectroscopy. The advantage of Raman spectroscopy is its high time efficiency and non-destructive nature. The results suggest that drug degradation can indeed be detected using Raman microscopy, but further research is needed to establish this approach for quantification or qualification of compounds. NanoRam®, a portable Raman spectrocope was also used alongside Raman microscopy but was unsuccessful in detecting degradation in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20stability" title="drug stability">drug stability</a>, <a href="https://publications.waset.org/abstracts/search?q=haloperidol" title=" haloperidol"> haloperidol</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC" title=" HPLC"> HPLC</a>, <a href="https://publications.waset.org/abstracts/search?q=phenytoin" title=" phenytoin"> phenytoin</a>, <a href="https://publications.waset.org/abstracts/search?q=raman%20spectroscopy" title=" raman spectroscopy"> raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=Swisslog" title=" Swisslog"> Swisslog</a> </p> <a href="https://publications.waset.org/abstracts/41916/determination-of-the-stability-of-haloperidol-tablets-and-phenytoin-capsules-stored-in-the-inpatient-dispensary-system-swisslog-by-the-respective-hplc-and-raman-spectroscopy-assay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41916.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">347</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">13</span> Effect of Cladding Direction on Residual Stress Distribution in Laser Cladded Rails</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taposh%20Roy">Taposh Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Paradowska"> Anna Paradowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Ralph%20Abrahams"> Ralph Abrahams</a>, <a href="https://publications.waset.org/abstracts/search?q=Quan%20Lai"> Quan Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Law"> Michael Law</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Mutton"> Peter Mutton</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Soodi"> Mehdi Soodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenyi%20Yan"> Wenyi Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this investigation, a laser cladding process with a powder feeding was used to deposit stainless steel 410L (high strength, excellent resistance to abrasion and corrosion, and great laser compatibility) onto railhead (higher strength, heat treated hypereutectoid rail grade manufactured in accordance with the requirements of European standard EN 13674 Part 1 for R400HT grade), to investigate the development and controllability of process-induced residual stress in the cladding, heat-affected zone (HAZ) and substrate and to analyse their correlation with hardness profile during two different laser cladding directions (across and along the track). Residual stresses were analysed by neutron diffraction at OPAL reactor, ANSTO. Neutron diffraction was carried out on the samples in longitudinal (parallel to the rail), transverse (perpendicular to the rail) and normal (through thickness) directions with high spatial resolution through the thickness. Due to the thick rail and thin cladding, 4 mm thick reference samples were prepared from every specimen by Electric Discharge Machining (EDM). Metallography across the laser claded sample revealed four distinct zones: The clad zone, the dilution zone, HAZ and the substrate. Compressive residual stresses were found in the clad zone and tensile residual stress in the dilution zone and HAZ. Laser cladding in longitudinally cladding induced higher tensile stress in the HAZ, whereas transversely cladding rail showed lower tensile behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laser%20cladding" title="laser cladding">laser cladding</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20stress" title=" residual stress"> residual stress</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20diffraction" title=" neutron diffraction"> neutron diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=HAZ" title=" HAZ"> HAZ</a> </p> <a href="https://publications.waset.org/abstracts/75838/effect-of-cladding-direction-on-residual-stress-distribution-in-laser-cladded-rails" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75838.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">273</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">12</span> Design and Analysis of a Piezoelectric Linear Motor Based on Rigid Clamping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chao%20Yi">Chao Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Cunyue%20Lu"> Cunyue Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lingwei%20Quan"> Lingwei Quan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Piezoelectric linear motors have the characteristics of great electromagnetic compatibility, high positioning accuracy, compact structure and no deceleration mechanism, which make it promising to applicate in micro-miniature precision drive systems. However, most piezoelectric motors are employed by flexible clamping, which has insufficient rigidity and is difficult to use in rapid positioning. Another problem is that this clamping method seriously affects the vibration efficiency of the vibrating unit. In order to solve these problems, this paper proposes a piezoelectric stack linear motor based on double-end rigid clamping. First, a piezoelectric linear motor with a length of only 35.5 mm is designed. This motor is mainly composed of a motor stator, a driving foot, a ceramic friction strip, a linear guide, a pre-tightening mechanism and a base. This structure is much simpler and smaller than most similar motors, and it is easy to assemble as well as to realize precise control. In addition, the properties of piezoelectric stack are reviewed and in order to obtain the elliptic motion trajectory of the driving head, a driving scheme of the longitudinal-shear composite stack is innovatively proposed. Finally, impedance analysis and speed performance testing were performed on the piezoelectric linear motor prototype. The motor can measure speed up to 25.5 mm/s under the excitation of signal voltage of 120 V and frequency of 390 Hz. The result shows that the proposed piezoelectric stacked linear motor obtains great performance. It can run smoothly in a large speed range, which is suitable for various precision control in medical images, aerospace, precision machinery and many other fields. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=piezoelectric%20stack" title="piezoelectric stack">piezoelectric stack</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20motor" title=" linear motor"> linear motor</a>, <a href="https://publications.waset.org/abstracts/search?q=rigid%20clamping" title=" rigid clamping"> rigid clamping</a>, <a href="https://publications.waset.org/abstracts/search?q=elliptical%20trajectory" title=" elliptical trajectory"> elliptical trajectory</a> </p> <a href="https://publications.waset.org/abstracts/112842/design-and-analysis-of-a-piezoelectric-linear-motor-based-on-rigid-clamping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112842.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">153</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">11</span> Effect of Golden Oyster Mushroom (Pleurotus citrinopileatus) Powder on Physiochemical, Antioxidative, and Sensory Properties of Noodles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giap%20Pham%20Ngoc%20Tram">Giap Pham Ngoc Tram</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Hong%20Quan"> Tran Hong Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Tieu%20Yen"> Tran Tieu Yen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Phung%20Tien"> Nguyen Phung Tien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of natural ingredients to enhance the nutritional and sensory properties of food products has gained significant interest in recent years. This study focuses on the effect of Golden oyster mushroom powder (GOMP) on the physiochemical, antioxidative, and sensory properties of noodles. The aim of this study is to investigate the influence of GOMP on the nutritional, antioxidant, and sensory properties of noodles. The study determined the color, moisture, total ash, protein, total phenolic, flavonoid contents, water activity, and antioxidant activity of GOMP and noodles. The incorporation of GOMP at levels of 5-15% increased the ash, protein, flavonoid, and total phenolic contents of the noodles. It also enhanced their antioxidant activities, as evidenced by improved DPPH radical scavenging activity and metal chelating activity. However, the incorporation of GOMP resulted in a decrease in the L* and b* values of the noodles. Furthermore, the GOMP-enriched noodles exhibited a lower cutting force compared to the control. This study highlights the potential of GOMP as a nutritional and antioxidant ingredient in noodle preparation. It adds to the existing literature by providing evidence of the positive effects of GOMP on the nutritional and functional properties of noodles. The researchers collected data on the physiochemical properties, nutritional contents, and antioxidant activities of GOMP and noodles. Statistical analysis was then performed to assess the differences between the control and GOMP-enriched noodles. The results of this study demonstrate that the inclusion of GOMP at the amount of 5-15% can increase the nutritional and antioxidant properties of noodles without significantly impacting sensory attributes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oyster%20mushroom" title="oyster mushroom">oyster mushroom</a>, <a href="https://publications.waset.org/abstracts/search?q=noodles" title=" noodles"> noodles</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical" title=" phytochemical"> phytochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20property" title=" sensory property"> sensory property</a> </p> <a href="https://publications.waset.org/abstracts/178292/effect-of-golden-oyster-mushroom-pleurotus-citrinopileatus-powder-on-physiochemical-antioxidative-and-sensory-properties-of-noodles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178292.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">65</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">10</span> Modeling and Temperature Control of Water-cooled PEMFC System Using Intelligent Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Jun-Hong">Chen Jun-Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=He%20Pu"> He Pu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Wen-Quan"> Tao Wen-Quan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Proton exchange membrane fuel cell (PEMFC) is the most promising future energy source owing to its low operating temperature, high energy efficiency, high power density, and environmental friendliness. In this paper, a comprehensive PEMFC system control-oriented model is developed in the Matlab/Simulink environment, which includes the hydrogen supply subsystem, air supply subsystem, and thermal management subsystem. Besides, Improved Artificial Bee Colony (IABC) is used in the parameter identification of PEMFC semi-empirical equations, making the maximum relative error between simulation data and the experimental data less than 0.4%. Operation temperature is essential for PEMFC, both high and low temperatures are disadvantageous. In the thermal management subsystem, water pump and fan are both controlled with the PID controller to maintain the appreciate operation temperature of PEMFC for the requirements of safe and efficient operation. To improve the control effect further, fuzzy control is introduced to optimize the PID controller of the pump, and the Radial Basis Function (RBF) neural network is introduced to optimize the PID controller of the fan. The results demonstrate that Fuzzy-PID and RBF-PID can achieve a better control effect with 22.66% decrease in Integral Absolute Error Criterion (IAE) of T_st (Temperature of PEMFC) and 77.56% decrease in IAE of T_in (Temperature of inlet cooling water) compared with traditional PID. In the end, a novel thermal management structure is proposed, which uses the cooling air passing through the main radiator to continue cooling the secondary radiator. In this thermal management structure, the parasitic power dissipation can be reduced by 69.94%, and the control effect can be improved with a 52.88% decrease in IAE of T_in under the same controller.
