However, nowadays, transshipment becomes the main business to many container terminals, especially in Southeast Asia (e.g. Hong Kong and Singapore). In these terminals, vessel arrivals are usually very frequent with small handling volume and very short staying time. Therefore, the traditional hourly-based modeling approach may cause significant berth and quay crane idling, and consequently cannot meet their practical needs. In this connection, a 15-minute-based modeling approach is requested by industrial practitioners. Accordingly, a Three-level Genetic Algorithm (3LGA) with Quay Crane (QC) shifting heuristics is designed to fulfill the research gap. The objective function here is to minimize the total service time. Preliminary numerical results show that the proposed 15-minute-based approach can reduce the berth and QC idling significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transshipment" title="transshipment">transshipment</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20berth%20allocation" title=" integrated berth allocation"> integrated berth allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=variable-in-time%20quay%20crane%20assignment" title=" variable-in-time quay crane assignment"> variable-in-time quay crane assignment</a>, <a href="https://publications.waset.org/abstracts/search?q=quay%20crane%20assignment" title=" quay crane assignment"> quay crane assignment</a> </p> <a href="https://publications.waset.org/abstracts/95988/a-15-minute-based-approach-for-berth-allocation-and-quay-crane-assignment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95988.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">169</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">378</span> Evaluation of Robust Feature Descriptors for Texture Classification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jia-Hong%20Lee">Jia-Hong Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mei-Yi%20Wu"> Mei-Yi Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsien-Tsung%20Kuo"> Hsien-Tsung Kuo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Texture is an important characteristic in real and synthetic scenes. Texture analysis plays a critical role in inspecting surfaces and provides important techniques in a variety of applications. Although several descriptors have been presented to extract texture features, the development of object recognition is still a difficult task due to the complex aspects of texture. Recently, many robust and scaling-invariant image features such as SIFT, SURF and ORB have been successfully used in image retrieval and object recognition. In this paper, we have tried to compare the performance for texture classification using these feature descriptors with k-means clustering. Different classifiers including K-NN, Naive Bayes, Back Propagation Neural Network , Decision Tree and Kstar were applied in three texture image sets － UIUCTex, KTH-TIPS and Brodatz, respectively. Experimental results reveal SIFTS as the best average accuracy rate holder in UIUCTex, KTH-TIPS and SURF is advantaged in Brodatz texture set. BP neuro network works best in the test set classification among all used classifiers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=texture%20classification" title="texture classification">texture classification</a>, <a href="https://publications.waset.org/abstracts/search?q=texture%20descriptor" title=" texture descriptor"> texture descriptor</a>, <a href="https://publications.waset.org/abstracts/search?q=SIFT" title=" SIFT"> SIFT</a>, <a href="https://publications.waset.org/abstracts/search?q=SURF" title=" SURF"> SURF</a>, <a href="https://publications.waset.org/abstracts/search?q=ORB" title=" ORB"> ORB</a> </p> <a href="https://publications.waset.org/abstracts/11046/evaluation-of-robust-feature-descriptors-for-texture-classification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11046.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">369</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">377</span> A Study on Unidirectional Analog Output Voltage Inverter for Capacitive Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun-Ki%20Hong">Sun-Ki Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Nam-HeeByeon"> Nam-HeeByeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Seop%20Lee"> Jung-Seop Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Sam%20Kang"> Tae-Sam Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For Common R or R-L load to apply arbitrary voltage, the bridge traditional inverters don’t have any difficulties by PWM method. However for driving some piezoelectric actuator, arbitrary voltage not a pulse but a steady voltage should be applied. Piezoelectric load is considered as R-C load and its voltage does not decrease even though the applied voltage decreases. Therefore it needs some special inverter with circuit that can discharge the capacitive energy. Especially for unidirectional arbitrary voltage driving like as sine wave, it becomes more difficult problem. In this paper, a charge and discharge circuit for unidirectional arbitrary voltage driving for piezoelectric actuator is proposed. The circuit has charging and discharging switches for increasing and decreasing output voltage. With the proposed simple circuit, the load voltage can have any unidirectional level with tens of bandwidth because the load voltage can be adjusted by switching the charging and discharging switch appropriately. The appropriateness is proved from the simulation of the proposed circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC-DC%20converter" title="DC-DC converter">DC-DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=analog%20output%20voltage" title=" analog output voltage"> analog output voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=sinusoidal%20drive" title=" sinusoidal drive"> sinusoidal drive</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric%20load" title=" piezoelectric load"> piezoelectric load</a>, <a href="https://publications.waset.org/abstracts/search?q=discharging%20circuit" title=" discharging circuit "> discharging circuit </a> </p> <a href="https://publications.waset.org/abstracts/8464/a-study-on-unidirectional-analog-output-voltage-inverter-for-capacitive-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8464.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">380</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">376</span> Numerical Approach of RC Structural MembersExposed to Fire and After-Cooling Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ju-young%20Hwang">Ju-young Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo-Gyoung%20Kwak"> Hyo-Gyoung Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Jae%20Yim"> Hong Jae Yim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces a numerical analysis method for reinforced-concrete (RC) structures exposed to fire and compares the result with experimental results. The proposed analysis method for RC structure under the high temperature consists of two procedures. First step is to decide the temperature distribution across the section through the heat transfer analysis by using the time-temperature curve. After determination of the temperature distribution, the nonlinear analysis is followed. By considering material and geometrical non-linearity with the temperature distribution, nonlinear analysis predicts the behavior of RC structure under the fire by the exposed time. The proposed method is validated by the comparison with the experimental results. Finally, Prediction model to describe the status of after-cooling concrete can also be introduced based on the results of additional experiment. The product of this study is expected to be embedded for smart structure monitoring system against fire in u-City. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RC%20structures" title="RC structures">RC structures</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer%20analysis" title=" heat transfer analysis"> heat transfer analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analysis" title=" nonlinear analysis"> nonlinear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=after-cooling%20concrete%20model" title=" after-cooling concrete model"> after-cooling concrete model</a> </p> <a href="https://publications.waset.org/abstracts/1959/numerical-approach-of-rc-structural-membersexposed-to-fire-and-after-cooling-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1959.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">375</span> Adopting a Systematically Planned Humour Pedagogical Approach to Increase Student Engagement in Higher Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rita%20Gill%20Singh">Rita Gill Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Chun%20Koon"> Alex Chun Koon</a>, <a href="https://publications.waset.org/abstracts/search?q=Cindy%20Sing%20Bik%20Ngai"> Cindy Sing Bik Ngai</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Wen%20Ying%20Ho"> Joanna Wen Ying Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Mei%20Li%20Khong"> Mei Li Khong</a>, <a href="https://publications.waset.org/abstracts/search?q=Enoch%20Chan"> Enoch Chan</a>, <a href="https://publications.waset.org/abstracts/search?q=Terrence%20Lau"> Terrence Lau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although humour is viewed as a beneficial element in teaching, there has been little attempt to systematize humour in teaching, possibly because it is difficult to teach someone to be humorous. This study integrated planned humour pedagogical approach into teaching and learning activities and examined the effect of systematically planned humour on students’ engagement and learning in different courses. Specifically, appropriate types of humour (i.e. analogy, absurdity and wordplay) and incorporation methods and frequency were systematically integrated into the lessons of courses at some higher education institutions in Hong Kong. The results showed that the planned humour pedagogical approach increased student engagement, as well as enhanced learning and motivation while reducing students’ stress.

However, nurses in these settings, in fact, have very low-level involvement in ACP discussions because of limited training in ACP conversations. Objective: This study aims to assess the impact of a multi-media experiential ACP (MEACP) training program, which is guided by the experiential learning model and theory of planned behaviour, on nurses' knowledge and confidence in assisting patients with ACP. Methodology: The study utilizes a cluster randomized controlled trial with a 12-week follow-up. Eligible nurses working in acute care hospital wards are randomly assigned at the ward level, in a 1:1 ratio, to either the control group (no ACP education) or the intervention group (4-week MEACP training program). The training programme includes training through a webpage and mobile application, as well as a face-to-face training workshop with enhanced lectures and role play, which is based on the Theory of Planned Behavior and Kolb's Experiential Learning Model. Questionnaires were distributed to assess nurses' knowledge (a 10-item true/false questionnaire) and level of confidence (five-point Likert scale) in ACP at baseline (T0), four weeks after the baseline assessment (T1), and 12 weeks after T1 (T2). In this interim report, data analysis was mainly descriptive in nature. Result: The interim report focuses on the preliminary results of 165 nurses at T0 (Control: 74, Intervention: 91) over a 5-month period, 69 nurses from the control group who completed the 4-week follow-up and 65 nurses from the intervention group who completed the 4-week MEACP training program at T1. The preliminary attrition rate is 6.8% and 28.6% for the control and intervention groups, respectively, as some nurses did not complete the whole set of online modules. At baseline, the two groups were generally homogeneous in terms of their years of nursing practice, weekly working hours, working title, and level of education, as well as ACP knowledge and confidence levels. The proportion of nurses who answered all ten knowledge questions correctly increased from 13.8% (T0) to 66.2% (T1) for the intervention group and from 13% (T0) to 20.3% (T1) for the control group. The nurses in the intervention group answered an average of 7.57 and 9.43 questions correctly at T0 and T1, respectively. They showed a greater improvement in the knowledge assessment at T1 with respect to T0 when compared with their counterparts in the control group (mean difference of change score, Δ=1.22). They also exhibited a greater gain in level of confidence at T1 compared to their colleagues in the control group (Δ=0.91). T2 data is yet available. Conclusion: The prevalence of nurses engaging in ACP and their level of knowledge about ACP in Hong Kong is low. The MEACP training program can enrich nurses by providing them with more knowledge about ACP and increasing their confidence in conducting ACP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advance%20directive" title="advance directive">advance directive</a>, <a href="https://publications.waset.org/abstracts/search?q=advance%20care%20planning" title=" advance care planning"> advance care planning</a>, <a href="https://publications.waset.org/abstracts/search?q=confidence" title=" confidence"> confidence</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-media%20experiential" title=" multi-media experiential"> multi-media experiential</a>, <a href="https://publications.waset.org/abstracts/search?q=randomised%20control%20trial" title=" randomised control trial"> randomised control trial</a> </p> <a href="https://publications.waset.org/abstracts/174549/the-effectiveness-of-multi-media-experiential-training-programme-on-advance-care-planning-in-enhancing-acute-care-nurses-knowledge-and-confidence-in-advance-care-planning-discussion-an-interim-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">373</span> A Meta-Analysis of Handwriting and Visual-Motor Integration (VMI): The Moderating Effect of Handwriting Dimensions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hong%20Lu">Hong Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Chen"> Xin Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhengcheng%20Fan"> Zhengcheng Fan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prior research has claimed a close association between handwriting and mathematics attainment with the help of spatial cognition. However, the exact mechanism behind this relationship remains un-investigated. Focusing on visual-motor integration (VMI), one critical spatial skill, this meta-analysis aims to estimate the size of the handwriting- visual-motor integration relationship and examine the moderating effect of handwriting dimensions on the link. With a random effect model, a medium relation (r=.26, 95%CI [.22, .30]) between handwriting and VMI was summarized in 38 studies with 55 unique samples and 141 effect sizes. Findings suggested handwriting dimensions significantly moderated the handwriting- VMI relationship, with handwriting legibility showing a substantial correlation with VMI, but neither handwriting speed nor pressure. Identifying the essential relationship between handwriting legibility and VMI, this study adds to the literature about the key cognitive processing needs underlying handwriting, and spatial cognition thus highlights the cognitive mechanism regarding handwriting, spatial cognition, and mathematics performances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=handwriting" title="handwriting">handwriting</a>, <a href="https://publications.waset.org/abstracts/search?q=visual-motor%20integration" title=" visual-motor integration"> visual-motor integration</a>, <a href="https://publications.waset.org/abstracts/search?q=legibility" title=" legibility"> legibility</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a> </p> <a href="https://publications.waset.org/abstracts/150140/a-meta-analysis-of-handwriting-and-visual-motor-integration-vmi-the-moderating-effect-of-handwriting-dimensions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150140.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">109</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">372</span> Screening Active Components in YPFS for Regulating Initiative Key Factors in Allergic Inflammation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dandan%20Shen">Dandan Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui-zhu%20Wang"> Hui-zhu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xi%20Yu"> Xi Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=LiLi%20Gui"> LiLi Gui</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiao%20Wei"> Xiao Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiao-yan%20Jiang"> Xiao-yan Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Da-wei%20Wang"> Da-wei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Hong"> Min Hong </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Yu-ping-feng-san (YPFS) is a clinical medicine for asthma and other allergic diseases, but the mechanism of YPFS on relapse of allergy is unclear. Currently, people come to realize the epithelial cells(EC) play a key role in stimulating and regulating local immune response. The study of thymic stromal lymphopoietin（TSLP derived from EC provides an important evidence that the EC can regulate immune response to stimulate allergic response. In this study, we observed the effect of YPFS on TSLP in vivo and in vitro. We established a method by using bronchial epithelial cells (16HBE) for screening potential bioactive components by HPLC-MS in YPFS and then analyzed the components in serum containing YPFS by UPLC-MS. The results showed that YPFS could decrease TSLP protein level in OVA-sensitized mice and 16HBE cells. Five components combing with the 16HBE cells were both detected in the serum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TSLP" title="TSLP">TSLP</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchial%20epithelial%20cells" title=" bronchial epithelial cells"> bronchial epithelial cells</a>, <a href="https://publications.waset.org/abstracts/search?q=cell-binding" title=" cell-binding"> cell-binding</a>, <a href="https://publications.waset.org/abstracts/search?q=drug-containing%20serum" title=" drug-containing serum"> drug-containing serum</a> </p> <a href="https://publications.waset.org/abstracts/2924/screening-active-components-in-ypfs-for-regulating-initiative-key-factors-in-allergic-inflammation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2924.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">512</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">371</span> The Effect of Floor Impact Sound Insulation Performance Using Scrambled Thermoplastic Poly Urethane and Ethylene Vinyl Acetate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bonsoo%20Koo">Bonsoo Koo</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Shin%20Hong"> Seong Shin Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung%20Kwon%20Lee"> Byung Kwon Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most of apartments in Korea have wall type structure that present poor performance regarding floor impact sound insulation.

However, rigid joint assumption has been generally used in the seismic response analysis of RC frames, in which two kinds of inelastic deformation of joint have been ignored. Based on OpenSees platform, ‘Super Joint Element Model’ with more detailed inelastic mechanism is used to simulate the inelastic response of joints. Two finite element models of typical RC plane frame, namely considering or ignoring the inelastic deformation of joint respectively, were established and analyzed under seven strong earthquake waves. The simulated global and local inelastic deformations of the RC plane frame is shown and discussed.

Therefore, silicon quantum wells (QWs) using these quantum phenomena could be a good candidate to achieve high performance silicon solar cells. The Al2O3/Si QW structures were fabricated by using the successive deposition technique, as a quantum confinement device to increase the effective energy bandgap and passivation effect in Si surface for the 3rd generation solar cell applications. In Si/Al2O3 QWs, the thicknesses of Si layers and Al2O3 layers were varied between 1 to 5 nm, respectively. The roughness of deposited Si on Al2O3 was less than 4 Å in the thickness of 2 nm. By using the Al2O3/Si QW structures on Si surfaces, the lifetime measured by u-PCD technique increased as a result of passivated surface effects. The discussion about the other properties such as electrical and optical properties of the QWs structures as well as the fabricated solar cells will be presented in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al2O3%2FSi%20quantum%20well" title="Al2O3/Si quantum well">Al2O3/Si quantum well</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20confinement" title=" quantum confinement"> quantum confinement</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=third%20generation" title=" third generation"> third generation</a>, <a href="https://publications.waset.org/abstracts/search?q=successive%20deposition%20technique" title=" successive deposition technique"> successive deposition technique</a> </p> <a href="https://publications.waset.org/abstracts/6308/fabrication-and-properties-of-al2o3si-quantum-well-structured-silicon-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6308.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">340</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">368</span> Suggestion of Reasonable Analysis Model for T-Girder Modular Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soonwon%20Kang">Soonwon Kang</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=Seung-Kyung%20Kye"> Seung-Kyung Kye</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> The modular bridge is to be constructed by assembling standardized precast segments.

In view of the fact that in Taiwan the majority of undergraduate college students reside in the dorms and dine out, the problem of restaurant sanitation is of utmost importance in their lives. The purpose of this study is to analyze students' dining habit and their perception of food safety. Four universities in the city of Tainan were randomly selected, and from each selected university a class was then chosen to receive 50 questionnaires. The total of 200 questionnaires yielded 144 usable returns. Students were asked to respond to questions, and each question was graded on a scale from 1 to 5 according to the importance. There were 32 questions ranging over various aspects: cleanliness of surroundings, washroom, food sanitation, serving temperature, kitchen sanitation, and service personnel cleanliness. It is found that the food sanitation received the highest score, while the service personnel ranked the lowest. An incidental finding is that the students tend to dine out in groups and as such their choice of restaurants are mostly dictated by consensus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title="food safety">food safety</a>, <a href="https://publications.waset.org/abstracts/search?q=restaurant" title=" restaurant"> restaurant</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20perception" title=" risk perception"> risk perception</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitation" title=" sanitation"> sanitation</a> </p> <a href="https://publications.waset.org/abstracts/83814/a-study-of-food-safety-perception-of-undergraduate-students-in-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83814.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">366</span> Circular Economy-Relationship of Natural Water Collection System, Afforestation and Country Park Towards Environmental Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwok%20Tak%20Kit">Kwok Tak Kit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The government and community have raised their awareness of the benefits of water reuse.

It is based on the use of an “all in one” prodrug, namely the biotinylated piperazine-rhodol conjugate 4a. This conjugate, which incorporates the anticancer drug SN-38, undergoes self-immolative cleavage when exposed to biological thiols. This leads to the tumor-targeted release of the active SN-38 payload along with fluorophore 1a. This release is made selective as the result of the biotin functionality. Fluorophore 1a is 32-fold more fluorescent than prodrug 4a. It permits the delivery and release of the SN-38 payload to be monitored easily in vitro and in vivo, as inferred from cell studies and ex vivo analyses of mice xenografts derived HeLa cells, respectively. Prodrug 4a also displays anticancer activity in the HeLa cell murine xenograft tumor model. On the basis of these findings we suggest that the present strategy, which combines within a single agent the key functions of targeting, release, imaging, and treatment, may have a role to play in cancer diagnosis and therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=theranostic" title="theranostic">theranostic</a>, <a href="https://publications.waset.org/abstracts/search?q=prodrug" title=" prodrug"> prodrug</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20therapy" title=" cancer therapy"> cancer therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence" title=" fluorescence"> fluorescence</a> </p> <a href="https://publications.waset.org/abstracts/16859/an-activatable-theranostic-for-targeted-cancer-therapy-and-imaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16859.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">537</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">364</span> Analog Voltage Inverter Drive for Capacitive Load with Adaptive Gain Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun-Ki%20Hong">Sun-Ki Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Ho%20Cho"> Yong-Ho Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ki-Seok%20Kim"> Ki-Seok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Sam%20Kang"> Tae-Sam Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Piezoelectric actuator is treated as RC load when it is modeled electrically. For some piezoelectric actuator applications, arbitrary voltage is required to actuate. Especially for unidirectional arbitrary voltage driving like as sine wave, some special inverter with circuit that can charge and discharge the capacitive energy can be used. In this case, the difference between power supply level and the object voltage level for RC load is varied. Because the control gain is constant, the controlled output is not uniform according to the voltage difference. In this paper, for charge and discharge circuit for unidirectional arbitrary voltage driving for piezoelectric actuator, the controller gain is controlled according to the voltage difference. With the proposed simple idea, the load voltage can have controlled smoothly although the voltage difference is varied. The appropriateness is proved from the simulation of the proposed circuit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analog%20voltage%20inverter" title="analog voltage inverter">analog voltage inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=capacitive%20load" title=" capacitive load"> capacitive load</a>, <a href="https://publications.waset.org/abstracts/search?q=gain%20control" title=" gain control"> gain control</a>, <a href="https://publications.waset.org/abstracts/search?q=dc-dc%20converter" title=" dc-dc converter"> dc-dc converter</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric" title=" piezoelectric"> piezoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20waveform" title=" voltage waveform"> voltage waveform</a> </p> <a href="https://publications.waset.org/abstracts/34752/analog-voltage-inverter-drive-for-capacitive-load-with-adaptive-gain-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34752.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">655</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">363</span> Efficient Antenna Array Beamforming with Robustness against Random Steering Mismatch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ju-Hong%20Lee">Ju-Hong Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Wei%20Liao"> Ching-Wei Liao</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun-Che%20Lee"> Kun-Che Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the problem of using antenna sensors for adaptive beamforming in the presence of random steering mismatch. We present an efficient adaptive array beamformer with robustness to deal with the considered problem. The robustness of the proposed beamformer comes from the efficient designation of the steering vector. Using the received array data vector, we construct an appropriate correlation matrix associated with the received array data vector and a correlation matrix associated with signal sources. Then, the eigenvector associated with the largest eigenvalue of the constructed signal correlation matrix is designated as an appropriate estimate of the steering vector. Finally, the adaptive weight vector required for adaptive beamforming is obtained by using the estimated steering vector and the constructed correlation matrix of the array data vector. Simulation results confirm the effectiveness of the proposed method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20beamforming" title="adaptive beamforming">adaptive beamforming</a>, <a href="https://publications.waset.org/abstracts/search?q=antenna%20array" title=" antenna array"> antenna array</a>, <a href="https://publications.waset.org/abstracts/search?q=linearly%20constrained%20minimum%20variance" title=" linearly constrained minimum variance"> linearly constrained minimum variance</a>, <a href="https://publications.waset.org/abstracts/search?q=robustness" title=" robustness"> robustness</a>, <a href="https://publications.waset.org/abstracts/search?q=steering%20vector" title=" steering vector"> steering vector</a> </p> <a href="https://publications.waset.org/abstracts/84543/efficient-antenna-array-beamforming-with-robustness-against-random-steering-mismatch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84543.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">199</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">362</span> Mexico's Steam Connections Across the Pacific (1867-1910)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruth%20Mandujano%20Lopez">Ruth Mandujano Lopez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the second half of the 19th century, in the transition from sail to steam navigation, the transpacific space underwent major transformation. This paper examines the role that the steamship companies between Mexico, the rest of North America and Asia played in that process. Based on primary sources found in Mexico, California, London and Hong Kong, it argues that these companies actively participated in the redefining of the Pacific space as they opened new routes, transported thousands of people and had an impact on regional geopolitics. In order to prove this, the text will present the cases of a handful of companies that emerged between 1867 and 1910 and of some of their passengers. By looking at the way the Mexican ports incorporated to the transpacific steam maritime network, this work contributes to have a better understanding of the role that Latin American ports have played in the formation of a global order. From a theoretical point of view, it proposes the conceptualization of space in the form of transnational networks as a point of departure to conceive a history that is truly global. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mexico" title="mexico">mexico</a>, <a href="https://publications.waset.org/abstracts/search?q=steamships" title=" steamships"> steamships</a>, <a href="https://publications.waset.org/abstracts/search?q=transpacific" title=" transpacific"> transpacific</a>, <a href="https://publications.waset.org/abstracts/search?q=maritime%20companies" title=" maritime companies"> maritime companies</a> </p> <a href="https://publications.waset.org/abstracts/186800/mexicos-steam-connections-across-the-pacific-1867-1910" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186800.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">48</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">361</span> Design and Fabrication of Micro-Bubble Oxygenator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chiang-Ho%20Cheng">Chiang-Ho Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=An-Shik%20Yang"> An-Shik Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong-Yih%20Cheng"> Hong-Yih Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper applies the MEMS technology to design and fabricate a micro-bubble generator by a piezoelectric actuator. Coupled with a nickel nozzle plate, an annular piezoelectric ceramic was utilized as the primary structure of the generator. In operations, the piezoelectric element deforms transversely under an electric field applied across the thickness of the generator. The surface of the nozzle plate can expand or contract because of the induction of radial strain, resulting in the whole structure to bend, and successively transport oxygen micro-bubbles into the blood flow for enhancing the oxygen content in blood. In the tests, a high magnification microscope and a high speed CCD camera were employed to photograph the time evolution of meniscus shape of gaseous bubbles dispensed from the micro-bubble generator for flow visualization. This investigation thus explored the bubble formation process including the influences of inlet gas pressure along with driving voltage and resonance frequency on the formed bubble extent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=micro-bubble" title="micro-bubble">micro-bubble</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygenator" title=" oxygenator"> oxygenator</a>, <a href="https://publications.waset.org/abstracts/search?q=nozzle" title=" nozzle"> nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoelectric" title=" piezoelectric"> piezoelectric</a> </p> <a href="https://publications.waset.org/abstracts/67526/design-and-fabrication-of-micro-bubble-oxygenator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67526.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">319</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">360</span> Cooling-Rate Induced Fiber Birefringence Variation in Regenerated High Birefringent Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Man-Hong%20Lai">Man-Hong Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinusha%20S.%20Gunawardena"> Dinusha S.

The results indicate that the birefringence of RPMG remains unchanged after CO2 laser annealing followed by a slow cooling process, but reduced after the fast cooling process (~5.6×10-5). After a series of annealing procedures with different cooling rates, the obtained results show that slower the cooling rate, higher the birefringence of RPMG. The volume, thermal expansion coefficient (TEC) and glass transition temperature (Tg) change of stress applying part in RPMG during the cooling process are responsible for the birefringence change. Therefore, these findings are important to the RPMG sensor in high and dynamic temperature environment. The measuring accuracy, range and sensitivity of RPMG sensor are greatly affected by its birefringence value.

Accordingly, the present study presents a methodology based on GPS, Bluetooth Low Energy (BLE) beacons, and Near Field Communication (NFC) technology. Through establishing graphic information and the design of algorithm, this study develops a guidance system for indoor and outdoor on smartphones, with aim to provide users a smart life through this system. The presented system is implemented on a smartphone and evaluated on a student campus environment.

This means floating floor can make worse noise condition when heavy-weight impact is applied. The amplified response is the result of interaction between finishing layer (mortar plate) and concrete slab. Because an impact force is not directly delivered to concrete slab, the impact force waveform or spectrum can be changed. In this paper, the changed impact spectrum was derived from several floating floor vibration tests. Based on the measured data, numerical modeling can describe the floating floor response, especially at low-frequency range. As a result, heavy-weight impact noise can be predicted using modified impact spectrum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=floating%20floor" title="floating floor">floating floor</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy-weight%20impact" title=" heavy-weight impact"> heavy-weight impact</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration" title=" vibration"> vibration</a> </p> <a href="https://publications.waset.org/abstracts/60227/prediction-of-heavy-weight-impact-noise-and-vibration-of-floating-floor-using-modified-impact-spectrum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60227.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">357</span> Evaluation for Punching Shear Strength of Slab-Column Connections with Ultra High Performance Fiber-Reinforced Concrete Overlay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20S.%20Youm">H.

The test results showed that by adding a thin layer of UHPFRC over the Reinforced Concrete (RC) substrates, considerable increases in global punching shear resistance up to 82% and structural rigidity were achieved. Furthermore, based on the cracking patterns the composite systems appeared to be governed by two failure modes: 1) diagonal shear failure in RC section and 2) debonding failure at the interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=punching%20shear%20strength" title="punching shear strength">punching shear strength</a>, <a href="https://publications.waset.org/abstracts/search?q=retrofit" title=" retrofit"> retrofit</a>, <a href="https://publications.waset.org/abstracts/search?q=slab-column%20connection" title=" slab-column connection"> slab-column connection</a>, <a href="https://publications.waset.org/abstracts/search?q=UHPFRC" title=" UHPFRC"> UHPFRC</a>, <a href="https://publications.waset.org/abstracts/search?q=UHPFRC%20overlay" title=" UHPFRC overlay"> UHPFRC overlay</a> </p> <a href="https://publications.waset.org/abstracts/80648/evaluation-for-punching-shear-strength-of-slab-column-connections-with-ultra-high-performance-fiber-reinforced-concrete-overlay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80648.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">258</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">356</span> Wall Pressure Fluctuations in Naturally Developing Boundary Layer Flows on Axisymmetric Bodies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chinsuk%20Hong">Chinsuk Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the characteristics of wall pressure fluctuations in naturally developing boundary layer flows on axisymmetric bodies experimentally. The axisymmetric body has a modified ellipsoidal blunt nose. Flush-mounted microphones are used to measure the wall pressure fluctuations in the boundary layer flow over the body. The measurements are performed in a low noise wind tunnel. It is found that the correlation between the flow regime and the characteristics of the pressure fluctuations is distinct. The process from small fluctuation in laminar flow to large fluctuation in turbulent flow is investigated. Tollmien-Schlichting wave (T-S wave) is found to generate and develop in transition.

To better understand and evaluate students’ thinking habits and abilities, GEF introduced Narrative Qualitative Analysis (NQA) in 2014 and has continued the study since then. Through the NQA study, a two-way evaluation scheme has been developed, including both student self-evaluation and teacher evaluation. This study will first introduce the theoretical background and research framework of the NQA study and then focus on student self-evaluation. An interactive online application, MASCOT, has been developed to facilitate students’ self-evaluation of their own thinking complexity. In this presentation, the design and development of MASCOT will be explained, and the main results will be reported when applying it in classroom teaching.

PB2 plays a role in overcoming the host barrier; however, the genetic prerequisites for avian PB2 to acquire mammalian pathogenic mutations have not been well elucidated. Here, we demonstrated that key amino acid mutations (I66M, I109V and I133V, collectively referred to as MVV) of prototypic avian PB2 increase the replication efficiency of recombinant PR8 virus carrying the mutated PB2 in both avian and mammalian hosts. The MVV mutations caused no weight loss in mice, but they did allow replication in infected lungs, and the viruses acquired fatal mammalian pathogenic mutations such as Q591R/K, E627K, or D701N in the infected lungs. The MVV mutations are located at the interfaces of the trimer and are predicted to increase the strength of this structure. Thus, gaining MVV mutations might be the first step for AIV to acquire mammalian pathogenicity. These results provide new insights into the evolution of AIV in birds and mammals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avian%20influenza%20A%20virus" title="avian influenza A virus">avian influenza A virus</a>, <a href="https://publications.waset.org/abstracts/search?q=prototypic%20PB2" title=" prototypic PB2"> prototypic PB2</a>, <a href="https://publications.waset.org/abstracts/search?q=polymerase%20activity" title=" polymerase activity"> polymerase activity</a>, <a href="https://publications.waset.org/abstracts/search?q=mammalian%20pathogenicity" title=" mammalian pathogenicity"> mammalian pathogenicity</a>, <a href="https://publications.waset.org/abstracts/search?q=first-step%20mutations" title=" first-step mutations"> first-step mutations</a> </p> <a href="https://publications.waset.org/abstracts/74659/prerequisites-for-the-acquisition-of-mammalian-pathogenicity-by-influenza-a-virus-with-a-prototypic-avian-pb2-gene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74659.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">345</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">352</span> Transparent Photovoltaic Skin for Artificial Thermoreceptor and Nociceptor Memory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Bhatnagar">Priyanka Bhatnagar</a>, <a href="https://publications.waset.org/abstracts/search?q=Malkeshkumar%20Patel"> Malkeshkumar Patel</a>, <a href="https://publications.waset.org/abstracts/search?q=Joondong%20Kim"> Joondong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Joonpyo%20Hong"> Joonpyo Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial skin and sensory memory platforms are produced using a flexible, transparent photovoltaic (TPV) device. The TPV device is composed of a metal oxide heterojunction (nZnO/p-NiO) and transmits visible light (> 50%) while producing substantial electric power (0.5 V and 200 μA cm-2 ). This TPV device is a transparent energy interface that can be used to detect signals and propagate information without an external energy supply. The TPV artificial skin offers a temperature detection range (0 C75 C) that is wider than that of natural skin (5 C48 °C) due to the temperature-sensitive pyrocurrent from the ZnO layer. Moreover, the TPV thermoreceptor offers sensory memory of extreme thermal stimuli. Much like natural skin, artificial skin uses the nociceptor mechanism to protect tissue from harmful damage via signal amplification (hyperalgesia) and early adaption (allodynia). This demonstrates the many features of TPV artificial skin, which can sense and transmit signals and memorize information under self-operation mode. This transparent photovoltaic skin can provide sustainable energy for use in human electronics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transparent" title="transparent">transparent</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaics" title=" photovoltaics"> photovoltaics</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20memory" title=" thermal memory"> thermal memory</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20skin" title=" artificial skin"> artificial skin</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoreceptor" title=" thermoreceptor"> thermoreceptor</a> </p> <a href="https://publications.waset.org/abstracts/149259/transparent-photovoltaic-skin-for-artificial-thermoreceptor-and-nociceptor-memory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149259.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">351</span> Transforming Water-Energy-Gas Industry through Smart Metering and Blockchain Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khoi%20A.%20Nguyen">Khoi A.

These providers will be able to concurrently collect a customers’ medium-high resolution water, electricity and gas demand data and provide user-friendly platforms to feed this information back to customers and supply/distribution utility organisations. With the emergence of blockchain technology, a new research area has been explored which helps bring this multi-utility service provider concept to a much higher level. This study aims at introducing a breakthrough system architecture where smart metering technology in water, energy, and gas (WEG) are combined with blockchain technology to provide customer a novel real-time consumption report and decentralized resource trading platform. A pilot study on 4 properties in Australia has been undertaken to demonstrate this system, where benefits for customers and utilities are undeniable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain" title="blockchain">blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20multi-utility" title=" digital multi-utility"> digital multi-utility</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20use" title=" end use"> end use</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20forecasting" title=" demand forecasting"> demand forecasting</a> </p> <a href="https://publications.waset.org/abstracts/83739/transforming-water-energy-gas-industry-through-smart-metering-and-blockchain-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83739.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">171</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">350</span> Recursive Doubly Complementary Filter Design Using Particle Swarm Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ju-Hong%20Lee">Ju-Hong Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ding-Chen%20Chung"> Ding-Chen Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the optimal design of recursive doubly complementary (DC) digital filter design using a metaheuristic based optimization technique. Based on the theory of DC digital filters using two recursive digital all-pass filters (DAFs), the design problem is appropriately formulated to result in an objective function which is a weighted sum of the phase response errors of the designed DAFs. To deal with the stability of the recursive DC filters during the design process, we can either impose some necessary constraints on the phases of the recursive DAFs. Through a frequency sampling and a weighted least squares approach, the optimization problem of the objective function can be solved by utilizing a population based stochastic optimization approach. The resulting DC digital filters can possess satisfactory frequency response. Simulation results are presented for illustration and comparison. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubly%20complementary"
