It is found that two types of plastic relaxation, dislocation debris and nanotwin, occurs in the displacive transformation due to relatively low transformation temperature and high carbon content. Because most carbon atoms trap in the dislocation, high dislocation density can be sustained during the tempering process. More carbides only can be found in the high tempered temperature due to intense recovery progression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanostructure%20bainitic%20steel" title="nanostructure bainitic steel">nanostructure bainitic steel</a>, <a href="https://publications.waset.org/abstracts/search?q=tempered" title=" tempered"> tempered</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-twin" title=" nano-twin"> nano-twin</a>, <a href="https://publications.waset.org/abstracts/search?q=dislocation%20debris" title=" dislocation debris"> dislocation debris</a>, <a href="https://publications.waset.org/abstracts/search?q=accommodation" title=" accommodation"> accommodation</a> </p> <a href="https://publications.waset.org/abstracts/5008/morphology-feature-of-nanostructure-bainitic-steel-after-tempering-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5008.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">535</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">1473</span> Variations and Fugue on an Ancient Taiwanese Music: The Art of Combining Taiwanese Traditional Music and Western Composition in Kuo Chih-Yuan's Piano Repertoire</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sheng-Wei%20Hsu">Sheng-Wei Hsu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Taiwanese composer Kuo Chih-Yuan (1921-2013) studied composition at Tokyo University of the Arts and was influenced by the musical nationalism prevailing in Japan at the time.

This study constructs an evolutionary game model of cross-basin ecological compensation in the Yangtze River Economic Belt (YREB), introducing a central government constraint and incentive mechanism (CGCIM) to explore the conditions for achieving strategies of protection and compensation that meet societal expectations. Furthermore, using a water quality-water quantity model combined with factual data from the YREB in 2020, the amount of ecological compensation is calculated. The results indicate that the stability of the evolutionary game model of the upstream and downstream governments in the YREB is closely related to the CGCIM. When the sum of the central government's reward amount to the upstream government and the penalty amount to both sides simultaneously is greater than 39.948 billion yuan, and the sum of the reward amount to the downstream government and the penalty amount to only the lower reaches is greater than 1.567 billion yuan, or when the sum of the reward amount to the downstream government and the penalty amount to both sides simultaneously is greater than 1.567 billion yuan, and the sum of the reward amount to the upstream government and the penalty amount to only the upstream government is greater than 399.48 billion yuan, the protection and compensation become the only evolutionarily stable strategy for the evolutionary game system composed of the upstream and downstream governments in the YREB. At this point, the total ecological compensation that the downstream government of the YREB should pay to the upstream government is 1.567 billion yuan, with Hunan paying 0.03 billion yuan, Hubei 2.53 billion yuan, Jiangxi 0.18 billion yuan, Anhui 1.68 billion yuan, Zhejiang 0.75 billion yuan, Jiangsu 6.57 billion yuan, and Shanghai 3.93 billion yuan. The research results can provide a reference for promoting the improvement and perfection of the cross-basin ecological compensation system in the YREB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20compensation" title="ecological compensation">ecological compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=evolutionary%20game%20model" title=" evolutionary game model"> evolutionary game model</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20government%20constraint%20and%20incentive%20mechanism" title=" central government constraint and incentive mechanism"> central government constraint and incentive mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=Yangtze%20river%20economic%20belt" title=" Yangtze river economic belt"> Yangtze river economic belt</a> </p> <a href="https://publications.waset.org/abstracts/183109/research-on-transverse-ecological-compensation-mechanism-in-yangtze-river-economic-belt-based-on-evolutionary-game-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183109.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">64</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">1471</span> Finding the Reaction Constant between Humic Acid and Aluminum Ion by Fluorescence Quenching Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen%20Po%20Cheng">Wen Po Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Zhao%20Feng"> Chen Zhao Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruey%20Fang%20Yu"> Ruey Fang Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Jia%20Jun"> Lin Jia Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Ji%20%20Ye"> Lin Ji Ye</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Yuan%20Wei"> Chen Yuan Wei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Humic acid was used as the removal target for evaluating the coagulation efficiency in this study. When the coagulant ions mix with a humic acid solution, a Fluorescence quenching effect may be observed conditionally. This effect can be described by Stern-Volmer linear equation which can be used for quantifying the quenching value (Kq) of the Fluorescence quenching effect. In addition, a Complex-Formation Titration (CFT) theory was conducted and the result was used to explain the electron-neutralization capability of the coagulant (AlCl₃) at different pH. The results indicated that when pH of the ACl₃ solution was between 6 and 8, fluorescence quenching effect obviously occurred. The maximum Kq value was found to be 102,524 at pH 6. It means that the higher the Kq value is, the better complex reaction between a humic acid and aluminum salts will be. Through the Kq value study, the optimum pH can be quantified when the humic acid solution is coagulated with aluminum ions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=humic%20acid" title="humic acid">humic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence%20quenching%20effect" title=" fluorescence quenching effect"> fluorescence quenching effect</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20reaction" title=" complex reaction"> complex reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=titration" title=" titration"> titration</a> </p> <a href="https://publications.waset.org/abstracts/92882/finding-the-reaction-constant-between-humic-acid-and-aluminum-ion-by-fluorescence-quenching-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92882.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">578</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">1470</span> Extensions to Chen's Minimizing Equal Mass Paralellogram Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdalla%20Manur">Abdalla Manur</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Offin"> Daniel Offin</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Arsie"> Alessandro Arsie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study the extension of the minimizing equal mass parallelogram solutions which was derived by Chen in 2001.

The defects or bobbles form inside the CsI(Na) during the solution or melt solidification. The defects or bobbles can further effect the x-ray path in the CsI(Na) crystal and decrease the scintillation characteristics of CsI(Na). In order to enhance the CsI(Na) scintillated property we made single crystal of CsI(Na) column in the anodic aluminum oxide (AAO) template by hydraulic pressure injection method. It is interesting that when CsI(Na) melt is confined in the small AAO channels, the column grow as stable single column without any dendrites. The high aspect ratio (100~10000) of AAO and nano to sub-micron channel structure which is a suitable template for single of crystal CsI(Na) formation. In this work, a new low-cost approach to fabricate scintillator crystals using anodic aluminum oxide (AAO) rather than Si is reported, which can produce scintillator crystals with a wide range of controllable size to optimize their performance in X-ray detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cesiumiodide" title="cesiumiodide">cesiumiodide</a>, <a href="https://publications.waset.org/abstracts/search?q=AAO" title=" AAO"> AAO</a>, <a href="https://publications.waset.org/abstracts/search?q=scintillator" title=" scintillator"> scintillator</a>, <a href="https://publications.waset.org/abstracts/search?q=crystal" title=" crystal"> crystal</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray" title=" X-ray"> X-ray</a> </p> <a href="https://publications.waset.org/abstracts/4389/the-fabrication-of-scintillator-column-by-hydraulic-pressure-injection-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4389.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">462</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">1468</span> The Threshold Values of Soil Water Index for Landslides on Country Road No.89</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Yuan%20Lin">Ji-Yuan Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Ming%20Liou"> Yu-Ming Liou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Ting%20Chen"> Yi-Ting Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen-Syuan%20Lin"> Chen-Syuan Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil water index obtained by tank model is now commonly used in soil and sand disaster alarm system in Japan. Comparing with the rainfall trigging index in Taiwan, the tank model is easy to predict the slope water content on large-scale landslide. Therefore, this study aims to estimate the threshold value of large-scale landslide using the soil water index Sixteen typhoons and heavy rainfall events, were selected to establish the, to relationship between landslide event and soil water index. Finally, the proposed threshold values for landslides on country road No.89 are suggested in this study. The study results show that 95% landslide cases occurred in soil water index more than 125mm, and 30% of the more serious slope failure occurred in the soil water index is greater than 250mm. Beside, this study speculates when soil water index more than 250mm and the difference value between second tank and third tank less than -25mm, it leads to large-scale landslide more probably. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20water%20index" title="soil water index">soil water index</a>, <a href="https://publications.waset.org/abstracts/search?q=tank%20model" title=" tank model"> tank model</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide" title=" landslide"> landslide</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20values" title=" threshold values"> threshold values</a> </p> <a href="https://publications.waset.org/abstracts/57064/the-threshold-values-of-soil-water-index-for-landslides-on-country-road-no89" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57064.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">387</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">1467</span> The High Quality Colored Wind Chimes by Anodization on Aluminum Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Chih%20Wei">Chia-Chih Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun-Qi%20Li"> Yun-Qi Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Ssu-Ying%20Chen"> Ssu-Ying Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsuan-Jung%20Chen"> Hsuan-Jung Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsi-Wen%20Yang"> Hsi-Wen Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Yuan%20Chen"> Chih-Yuan Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Chon%20Chen"> Chien-Chon Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we used high quality anodization technique to make colored wind chime with a nano-tube structure anodic film, which controls the length to diameter ratio of an aluminum rod and controls the oxide film structure on the surface of the aluminum rod by anodizing method. The research experiment used hard anodization to grow a controllable thickness of anodic film on aluminum alloy surface. The hard anodization film has high hardness, high insulation, high temperature resistance, good corrosion resistance, colors, and mass production properties can be further applied to transportation, electronic products, biomedical fields, or energy industry applications. This study also in-depth research and detailed discussion in the related process of aluminum alloy surface hard anodizing including pre-anodization, anodization, and post-anodization. The experiment parameters of anodization including using a mixed acid solution of sulfuric acid and oxalic acid as an anodization electrolyte, and control the temperature, time, current density, and final voltage to obtain the anodic film.

Epithelial-mesenchymal transition (EMT) has been implicated as a key mechanism in the pathogenesis of organ fibrosis. MiR-200a has been shown to repress EMT. We aim to explore the role of miR-200a in the fibrogenesis of BA. Methods: We obtained the plasma samples and liver samples from patients with BA or controls to examine the role of miR-200a. Histological liver fibrosis was assessed using the Ishak fibrosis scores. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed to detect the expression of miR-200a in plasma. We also evaluated the expression of miR-200a in liver tissues using tyramide signal amplification fluorescence in situ hybridization (TSA-FISH). The expression of EMT related proteins zinc finger E-box-binding homeobox 1 (ZEB1), E-cadherin and α-smooth muscle actin (α-SMA) in the liver sections were detected by immunohistochemical staining. Results: We found that the expression of miR-200a was both elevated in the plasma and liver tissues from BA patients compared with the controls. The hepatic expression of ZEB1 and α-SMA were markedly increased in the liver sections from BA patients compared to the controls, whereas E-cadherin was downregulated in the BA group. Simultaneously, we noted that the hepatic expression of miR-200a, E-cadherin and α-SMA were upregulated with the progression of liver fibrosis in the BA group, while ZEB1 was downregulated with the progression of liver fibrosis in BA patients. Conclusion: These findings suggest EMT has a critical effect on the fibrotic process of BA, and the interaction between miR-200a and ZEB1 may regulate EMT and eventually influence liver fibrogenesis of BA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biliary%20atresia" title="biliary atresia">biliary atresia</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20fibrosis" title=" liver fibrosis"> liver fibrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=MicroRNA" title=" MicroRNA"> MicroRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=epithelial-mesenchymal%20transition" title=" epithelial-mesenchymal transition"> epithelial-mesenchymal transition</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20finger%20E-box-binding%20homeobox%201" title=" zinc finger E-box-binding homeobox 1"> zinc finger E-box-binding homeobox 1</a> </p> <a href="https://publications.waset.org/abstracts/53847/mir-200azeb1-pathway-in-liver-fibrogenesis-of-biliary-atresia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53847.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">359</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">1465</span> Macroeconomic Reevaluation of CNY/USD Exchange Rate: Quantitative Impact on EUR/USD Exchange Rate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Henry">R.

Eighteen children (age: 9.38 ± 0.27 years old) were recruited as the participants for this study, and asked to assess RT and balance performance separately and simultaneously as following five conditions: simple RT (0-bit decision), choice RT (1-bit decision), single balance control, balance control with simple RT, and balance control with choice RT. Biodex 950-300 balance system and You-Shang response timer were used to record and analyze the postural stability and information processing speed (RT) respectively for the participants. Repeated measures one-way ANOVA with HSD post-hoc test and 2 (balance) × 2 (amount of information processing) repeated measures two-way ANOVA were used to test the parameters of balance performance and RT (α = .05). The results showed the overall stability index in the 1-bit decision was lower than in 0-bit decision, and the mean deflection in the 1-bit decision was lower than in single balance performance. Simple RTs were faster than choice RTs both in single task condition and dual task condition. It indicated that the chronometric approach of RT could use to infer the attention requirement of the secondary task. However, this study did not find that the balance performance is interfered for children by the increasing of the amount of information processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacity%20theory" title="capacity theory">capacity theory</a>, <a href="https://publications.waset.org/abstracts/search?q=reaction%20time" title=" reaction time"> reaction time</a>, <a href="https://publications.waset.org/abstracts/search?q=Hick%E2%80%99s%20law" title=" Hick’s law"> Hick’s law</a>, <a href="https://publications.waset.org/abstracts/search?q=balance" title=" balance"> balance</a> </p> <a href="https://publications.waset.org/abstracts/69526/the-amount-of-information-processing-and-balance-performance-in-children-the-dual-task-paradigm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69526.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">452</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">1463</span> Ultra-Low Loss Dielectric Properties of (Mg1-xNix)2(Ti0.95Sn0.05)O4 Microwave Ceramics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bing-Jing%20Li">Bing-Jing Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Sih-Yin%20Wang"> Sih-Yin Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tse-Chun%20Yeh"> Tse-Chun Yeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan-Bin%20Chen"> Yuan-Bin Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microwave dielectric ceramic materials of (Mg1-xNix)2(Ti0.95Sn0.05)O4 for x = 0.01, 0.03, 0.05, 0.07 and 0.09 were prepared and sintered at 1250–1400ºC.

An excessively high p-n junction temperature minimizes the output flux of LEDs, decreasing their brightness and influencing the photon wavelength; consequently, the operating life of LEDs decreases and their luminous output changes. The maximum limit of the p-n junction temperature of LEDs is approximately 120 °C. The purpose of this research was to devise an approach for dissipating heat generated in a confined space when LEDs operate at low temperatures to reduce light decay. The cooling mode of existing commercial LED lights can be divided into natural- and forced convection cooling. In natural convection cooling, the volume of LED encapsulants must be increased by adding more fins to increase the cooling area. However, this causes difficulties in achieving efficient LED lighting at high power. Compared with forced convection cooling, heat transfer through water convection is associated with a higher heat transfer coefficient per unit area; therefore, we dissipated heat by using a closed loop water cooling system. Nevertheless, cooling water exposed to air can be easily influenced by environmental factors. Thus, we incorporated a ground heat exchanger into the water cooling system to minimize the influence of air on cooling water and then observed the relationship between the amounts of heat dissipated through the ground and LED efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=helical%20ground%20heat%20exchanger" title="helical ground heat exchanger">helical ground heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20power%20LED" title=" high power LED"> high power LED</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20source%20cooling%20system" title=" ground source cooling system"> ground source cooling system</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20dissipation" title=" heat dissipation"> heat dissipation</a> </p> <a href="https://publications.waset.org/abstracts/34341/thermal-management-of-ground-heat-exchangers-applied-in-high-power-led" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34341.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">579</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">1461</span> Discovery the Relics of Buddhist Stupa at Thanesar, Kurukshetra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chander%20Shekhar">Chander Shekhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Kumar"> Manoj Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Present paper deal with the discovery of the stupa’s relics which belongs to the Kushana period.

It has been agreed upon that orthodontic tooth movement is based on the ability of surrounding bone and periodontal ligament (PDL) to react to a mechanical stimulus with remodeling processes. However, the mechanism of the tooth movement is still unclear. Recent studies focus on the simple principle compression-tension theory while rare studies directly measure tooth movement. Therefore, tracking tooth movement information during orthodontic treatment is very important in clinical practice. The aim of this study is to investigate the mechanism responses of the tooth movement during the orthodontic treatments. A stereovision system applied to track the tooth movement of the patient with the stamp brackets. The system was established by two cameras with their relative position calibrate. And the orthodontic force measured by 3D printing model with the six-axis load cell to determine the initial force application. The result shows that the stereovision system accuracy revealed the measurement presents a maximum error less than 2%. For the study on patient tracking, the incisor moved about 0.9 mm during 60 days tracking, and half of movement occurred in the first few hours. After removing the orthodontic force in 100 hours, the distance between before and after position incisor tooth decrease 0.5 mm consisted with the release of the phenomenon. Using the stereovision system can accurately locate the three-dimensional position of the teeth and superposition of 3D coordinate system for all the data to integrate the complex tooth movement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=orthodontic%20treatment" title="orthodontic treatment">orthodontic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=tooth%20movement" title=" tooth movement"> tooth movement</a>, <a href="https://publications.waset.org/abstracts/search?q=stereovision%20system" title=" stereovision system"> stereovision system</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20tracking" title=" long-term tracking"> long-term tracking</a> </p> <a href="https://publications.waset.org/abstracts/45507/observation-of-the-orthodontic-tooths-long-term-movement-using-stereovision-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">421</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1457</span> Compact Dual-Band Bandpass Filter Based on Quarter Wavelength Stepped Impedance Resonators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Fu%20Chen">Yu-Fu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Zih-Jyun%20Dai"> Zih-Jyun Dai</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen-Te%20Chiu"> Chen-Te Chiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiue-Chen%20Chiou"> Shiue-Chen Chiou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yung-Wei%20Chen"> Yung-Wei Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Ming%20Lin"> Yu-Ming Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuan-Yu%20Chen"> Kuan-Yu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung-Wei%20Wu"> Hung-Wei Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-Ying%20Lee"> Hsin-Ying Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan-Kuin%20Su"> Yan-Kuin Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Shoou-Jinn%20Chang"> Shoou-Jinn Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a compact dual-band bandpass filter that involves using the quarter wavelength stepped impedance resonators (SIRs) for achieving simultaneously compact circuit size and good dual-band performance. The filter is designed at 2.4 / 3.5 GHz and constructed by two pairs of quarter wavelength SIRs and source-load lines. By properly tuning the impedance ratio, length ratio and radius of via hole of the SIRs, dual-passbands performance can be easily determined. To improve the passband selectivity, the use of source-load lines is to increase coupling energy between the resonators. The filter is showing simple configuration, effective design method and small circuit size. The measured results are in good agreement with the simulation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual-band" title="dual-band">dual-band</a>, <a href="https://publications.waset.org/abstracts/search?q=bandpass%20filter" title=" bandpass filter"> bandpass filter</a>, <a href="https://publications.waset.org/abstracts/search?q=stepped%20impedance%20resonators" title=" stepped impedance resonators"> stepped impedance resonators</a>, <a href="https://publications.waset.org/abstracts/search?q=SIR" title=" SIR"> SIR</a> </p> <a href="https://publications.waset.org/abstracts/44601/compact-dual-band-bandpass-filter-based-on-quarter-wavelength-stepped-impedance-resonators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44601.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">517</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">1456</span> At Home in This World: Nanyang Painter Georgette Chen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christine%20C.%20Neal">Christine C.

Although the performance of hot work tool steel can be improved better by alloy composition design strategy, the influence of processing parameters on the mechanical property, especially on the service life of hot work tool steel, is still not fully understood yet. A longer service life of hot work tool steel can decrease the manufacturing cost effectively and thus become a research hot spot. According to several previous studies, it is generally acknowledged the service life of hot work tool steels can be increased effectively as the steels possessing higher hardness and toughness due to the formation and propagation of microcracks within the steel can be inhibited effectively. Therefore, in the present research, the designed experiments are primarily to explore the synergistic effect of nitrogen content and austenitization conditioning on the mechanical properties of hot work tool steels has been conducted and analyzed. No matter the nitrogen content, the results indicated the hardness of hot work tool steels increased as the austenitization treatment executed at higher temperature. On the other hand, an optimum toughness of hot work tool steel can be achieved as the austenitization treatment performed at a suitable temperature range. The possible explanation of such metallurgical phenomenon has been also proposed and analyzed in the present research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20work%20tool%20steel" title="hot work tool steel">hot work tool steel</a>, <a href="https://publications.waset.org/abstracts/search?q=Cr-Mo-V" title=" Cr-Mo-V"> Cr-Mo-V</a>, <a href="https://publications.waset.org/abstracts/search?q=toughness" title=" toughness"> toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a> </p> <a href="https://publications.waset.org/abstracts/176209/the-effect-of-austenitization-conditioning-on-the-mechanical-properties-of-cr-mo-v-hot-work-tool-steel-with-different-nitrogen-addition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176209.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">59</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">1454</span> Half-Circle Fuzzy Number Threshold Determination via Swarm Intelligence Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20W.%20Tsai">P.

This study investigates the relationships between their citizenship acquisition and whether they develop Taiwanese identities. One hundred and ninety-two immigrant women were measured using Multigroup Ethnic Identity Measure-Revised and a global 10-point ethnic identity question. Correlation tests and hierarchical regression were performed to explore whether acquiring citizenship would help immigrant women to develop Taiwanese identities. The results revealed that citizenship acquisition does help immigrant women to identify with Taiwanese society symbolically. However, the results also indicated that acquiring citizenship would not help these immigrant women become involved in deeper cultural exploration of Taiwan nor would it encourage them to make commitments to the host society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=immigrants" title="immigrants">immigrants</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20marriage" title=" international marriage"> international marriage</a>, <a href="https://publications.waset.org/abstracts/search?q=ethnic%20identity" title=" ethnic identity"> ethnic identity</a>, <a href="https://publications.waset.org/abstracts/search?q=Taiwan" title=" Taiwan"> Taiwan</a> </p> <a href="https://publications.waset.org/abstracts/9488/the-relationships-between-citizenship-acquisition-and-ethnic-identity-of-immigrant-women-in-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9488.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">418</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">1452</span> Sliding Mode Position Control for Permanent Magnet Synchronous Motors Based on Passivity Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jenn-Yih%20Chen">Jenn-Yih Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Bean-Yin%20Lee"> Bean-Yin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan-Chuan%20Hsu"> Yuan-Chuan Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jui-Cheng%20Lin"> Jui-Cheng Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuang-Chyi%20Lee"> Kuang-Chyi Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a sliding mode control method based on the passivity approach is proposed to control the position of surface-mounted permanent magnet synchronous motors (PMSMs). Firstly, the dynamics of a PMSM was proved to be strictly passive. The position controller with an adaptive law was used to estimate the load torque to eliminate the chattering effects associated with the conventional sliding mode controller. The stability analysis of the overall position control system was carried out by adopting the passivity theorem instead of Lyapunov-type arguments. Finally, experimental results were provided to show that the good position tracking can be obtained, and exhibit robustness in the variations of the motor parameters and load torque disturbances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20law" title="adaptive law">adaptive law</a>, <a href="https://publications.waset.org/abstracts/search?q=passivity%20theorem" title=" passivity theorem"> passivity theorem</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20synchronous%20motor" title=" permanent magnet synchronous motor"> permanent magnet synchronous motor</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control" title=" sliding mode control"> sliding mode control</a> </p> <a href="https://publications.waset.org/abstracts/10734/sliding-mode-position-control-for-permanent-magnet-synchronous-motors-based-on-passivity-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10734.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">468</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">1451</span> Structural Safety Assessment of Transmission Tower with High-Low Legs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi-Rung%20Jiang">Chi-Rung Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Chung%20Chen"> Chun-Chung Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheng-Yuan%20Shiao"> Sheng-Yuan Shiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Fang-Yao%20Yeh"> Fang-Yao Yeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transmission lines are essential for power systems which play a significant role in a city for the development of infrastructures. Once a tower on the transmission line is damaged or becomes unstable, small-scale transmission tower damage might cause a large-scale electric power failure, and consequently, the enormous economic losses will occur. This paper assesses the structural safety and considers the impact of earthquakes and winds, presents a preliminary study of transmission tower with high-low legs by building structural analysis models of towers. The result shows that the high-low legs towers do have some structural characteristics need to be considered, such as the length of the difference of high legs and low legs should be restricted and the deployment direction of legs must be carefully planned during the design of transmission towers.

The in-vivo MRI study showed that there was a stronger T2-weighted signal enhancement for the group under a magnetic field, and hence it indicated that this group had a better accumulation of SPIO-PEG than the group without a magnetic field. In the anticancer evaluation of SPIO-PEG-D, the group with a magnetic field displayed a significantly smaller tumor size than the group without.

Descriptive statistics will be used to describe the means, standard deviations, and adjusted means for the tests between the two groups. Next, analysis of covariance (ANCOVA) will be used to compare the final results of the two research groups after 6 weeks of instruction. Statistics gathered in the end of the research can be used to make contrasts.

In this study, 20%, 30% and 50% glandularity phantoms were exposed using a mammography machine at 28, 30 and 31 kVp, and 30, 55, 80 and 105 mAs, respectively. The regions of interest (ROIs) were drawn to assess the gray level. The relationship between the glandularity and gray level under various compression thicknesses, kVp, and mAs was established by the multivariable linear regression. A phantom verification was performed with automatic exposure control (AEC). The regression equation was obtained with an R-square value of 0.928. The average gray levels of the verification phantom were 8708, 8660 and 8434 for 0.952, 0.963 and 0.985 g/cm3, respectively. The percent differences of glandularity to the regression equation were 3.24%, 2.75% and 13.7%. We concluded that the proposed method could be clinically applied in mammography to improve the glandularity estimation and further increase the importance of breast cancer screening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mammography" title="mammography">mammography</a>, <a href="https://publications.waset.org/abstracts/search?q=glandularity" title=" glandularity"> glandularity</a>, <a href="https://publications.waset.org/abstracts/search?q=gray%20value" title=" gray value"> gray value</a>, <a href="https://publications.waset.org/abstracts/search?q=BI-RADS" title=" BI-RADS"> BI-RADS</a> </p> <a href="https://publications.waset.org/abstracts/60797/assessing-relationships-between-glandularity-and-gray-level-by-using-breast-phantoms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60797.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">492</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">1447</span> Development of 35kV SF6 Phase-Control Circuit Breaker Equipped with EFDA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duanlei%20Yuan">Duanlei Yuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Guangchao%20Yan"> Guangchao Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhanqing%20Chen"> Zhanqing Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xian%20Cheng"> Xian Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper mainly focuses on the problem that high voltage circuit breaker’s closing and opening operation at random phase brings harmful electromagnetic transient effects on the power system. To repress the negative transient effects, a 35 kV SF6 phase-control circuit breaker equipped with electromagnetic force driving actuator is designed in this paper. Based on the constructed mathematical and structural models, the static magnetic field distribution and dynamic properties of the under loading actuator are simulated. The prototype of 35 kV SF6 phase-control circuit breaker is developed based on theories analysis and simulation. Tests are carried on to verify the operating reliability of the prototype. The developed circuit breaker can control its operating speed intelligently and switches with phase selection. Results of the tests and simulation prove that the phase-control circuit breaker is feasible for industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase-control" title="phase-control">phase-control</a>, <a href="https://publications.waset.org/abstracts/search?q=circuit%20breaker" title=" circuit breaker"> circuit breaker</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20force%20driving%20actuator" title=" electromagnetic force driving actuator"> electromagnetic force driving actuator</a>, <a href="https://publications.waset.org/abstracts/search?q=tests%20and%20simulation" title=" tests and simulation"> tests and simulation</a> </p> <a href="https://publications.waset.org/abstracts/38008/development-of-35kv-sf6-phase-control-circuit-breaker-equipped-with-efda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38008.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">396</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">1446</span> An Approaching Index to Evaluate a forward Collision Probability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuan-Lin%20Chen">Yuan-Lin Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an approaching forward collision probability index (AFCPI) for alerting and assisting driver in keeping safety distance to avoid the forward collision accident in highway driving. The time to collision (TTC) and time headway (TH) are used to evaluate the TTC forward collision probability index (TFCPI) and the TH forward collision probability index (HFCPI), respectively. The Mamdani fuzzy inference algorithm is presented combining TFCPI and HFCPI to calculate the approaching collision probability index of the vehicle. The AFCPI is easier to understand for the driver who did not even have any professional knowledge in vehicle professional field. At the same time, the driver’s behavior is taken into account for suiting each driver. For the approaching index, the value 0 is indicating the 0% probability of forward collision, and the values 0.5 and 1 are indicating the 50% and 100% probabilities of forward collision, respectively. The AFCPI is useful and easy-to-understand for alerting driver to avoid the forward collision accidents when driving in highway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=approaching%20index" title="approaching index">approaching index</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20collision%20probability" title=" forward collision probability"> forward collision probability</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20to%20collision" title=" time to collision"> time to collision</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20headway" title=" time headway"> time headway</a> </p> <a href="https://publications.waset.org/abstracts/74855/an-approaching-index-to-evaluate-a-forward-collision-probability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74855.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">293</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">1445</span> Tribological Study of TiC Powder Cladding on 6061 Aluminum Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuan-Ching%20Lin">Yuan-Ching Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sin-Yu%20Chen"> Sin-Yu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei-Yu%20Wu"> Pei-Yu Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study reports the improvement in the wear performance of A6061 aluminum alloy clad with mixed powders of titanium carbide (TiC), copper (Cu) and aluminum (Al) using the gas tungsten arc welding (GTAW) method. The wear performance of the A6061 clad layers was evaluated by performing pin-on-disc mode wear test. Experimental results clearly indicate an enhancement in the hardness of the clad layer by about two times that of the A6061 substrate without cladding. Wear test demonstrated a significant improvement in the wear performance of the clad layer when compared with the A6061 substrate without cladding. Moreover, the interface between the clad layer and the A6061 substrate exhibited superior metallurgical bonding. Due to this bonding, the clad layer did not spall during the wear test; as such, massive wear loss was prevented. Additionally, massive oxidized particulate debris was generated on the worn surface during the wear test; this resulted in three-body abrasive wear and reduced the wear behavior of the clad surface.
