Hence, in order to select the best formulae, the bed load equations should be evaluated. The affecting factors need to be scrutinized, and equations should be verified. Also, re-evaluation may be needed. In this research, sediment bed load of Dez Dam at Tal-e Zang Station has been studied. After reviewing the available references, the most common formulae were selected that included Meir-Peter and Muller, using MS Excel to compute and evaluate data. Then, 52 series of already measured data at the station were re-measured, and the sediment bed load was determined. 1. The calculated bed load obtained by different equations showed a great difference with that of measured data. 2. r difference ratio from 0.5 to 2.00 was 0% for all equations except for Nilsson and Shields equations while it was 61.5 and 59.6% for Nilsson and Shields equations, respectively. 3. By reviewing results and discarding probably erroneous measured data measurements (by human or machine), one may use Nilsson Equation due to its r value higher than 1 as an effective equation for estimating bed load at Tal-e Zang Station in order to predict activities that depend upon bed sediment load estimate to be determined. Also, since only few studies have been conducted so far, these results may be of assistance to the operators and consulting companies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bed%20load" title="bed load">bed load</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20relation%20ship" title=" empirical relation ship"> empirical relation ship</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=Tale%20Zang%20Station" title=" Tale Zang Station"> Tale Zang Station</a> </p> <a href="https://publications.waset.org/abstracts/54461/nilsson-model-performance-in-estimating-bed-load-sediment-case-study-tale-zang-station" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54461.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">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Analysis and Experimental Research on the Influence of Lubricating Oil on the Transmission Efficiency of New Energy Vehicle Gearbox</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Yong">Chen Yong</a>, <a href="https://publications.waset.org/abstracts/search?q=Bi%20Wangyang"> Bi Wangyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zang%20Libin"> Zang Libin</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Jinkai"> Li Jinkai</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Xiaowei"> Cheng Xiaowei</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Jinmin"> Liu Jinmin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Miao"> Yu Miao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New energy vehicle power transmission systems continue to develop in the direction of high torque, high speed, and high efficiency. The cooling and lubrication of the motor and the transmission system are integrated, and new requirements are placed on the lubricants for the transmission system. The effects of traditional lubricants and special lubricants for new energy vehicles on transmission efficiency were studied through experiments and simulation methods. A mathematical model of the transmission efficiency of the lubricating oil in the gearbox was established. The power loss of each part was analyzed according to the working conditions. The relationship between the speed and the characteristics of different lubricating oil products on the power loss of the stirring oil was discussed. The minimum oil film thickness was required for the life of the gearbox. The accuracy of the calculation results was verified by the transmission efficiency test conducted on the two-motor integrated test bench. The results show that the efficiency increases first and then decreases with the increase of the speed and decreases with the increase of the kinematic viscosity of the lubricant. The increase of the kinematic viscosity amplifies the transmission power loss caused by the high speed. New energy vehicle special lubricants have less attenuation of transmission efficiency in the range above mid-speed. The research results provide a theoretical basis and guidance for the evaluation and selection of transmission efficiency of gearbox lubricants for new energy vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20energy%20vehicles" title="new energy vehicles">new energy vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricants" title=" lubricants"> lubricants</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20efficiency" title=" transmission efficiency"> transmission efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematic%20viscosity" title=" kinematic viscosity"> kinematic viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20and%20simulation" title=" test and simulation"> test and simulation</a> </p> <a href="https://publications.waset.org/abstracts/128894/analysis-and-experimental-research-on-the-influence-of-lubricating-oil-on-the-transmission-efficiency-of-new-energy-vehicle-gearbox" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128894.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">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> The Role of Hypothalamus Mediators in Energy Imbalance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maftunakhon%20Latipova">Maftunakhon Latipova</a>, <a href="https://publications.waset.org/abstracts/search?q=Feruza%20Khaydarova"> Feruza Khaydarova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obesity is considered a chronic metabolic disease that occurs at any age. Regulation of body weight in the body is carried out through complex interaction of a complex of interrelated systems that control the body's energy system. Energy imbalance is the cause of obesity and overweight, in which the supply of energy from food exceeds the energy needs of the body. Obesity is closely related to impaired appetite regulation, and a hypothalamus is a key place for neural regulation of food consumption. The nucleus of the hypothalamus is connected and interdependent on receiving, integrating and sending hunger signals to regulate appetite. Purpose of the study: to identify markers of food behavior. Materials and methods: The screening was carried out to identify eating disorders in 200 men and women aged 18 to 35 years with overweight and obesity and to check the effects of Orexin A and Neuropeptide Y markers. A questionnaire and questionnaires were conducted with over 200 people aged 18 to 35 years. Questionnaires were for eating disorders and hidden depression (on the Zang scale). Anthropometry is measured by OT, OB, BMI, Weight, and Height. Based on the results of the collected data, 3 groups were divided: People with obesity, People with overweight, Control Group of Healthy People. Results: Of the 200 analysed persons, 86% had eating disorders. Of these, 60% of eating disorders were associated with childhood. According to the Zang test result: Normal condition was about 37%, mild depressive disorder 20%, moderate depressive disorder 25% and 18% of people suffered from severe depressive disorder without knowing it. One group of people with obesity had eating disorders and moderate and severe depressive disorder, and group 2 was overweight with mild depressive disorder. According to laboratory data, the first group had the lowest concentration of Orexin A and Neuropeptide U in blood serum. Conclusions: Being overweight and obese are the first signal of many diseases, and prevention and detection of these disorders will prevent various diseases, including type 2 diabetes. Obesity etiology is associated with eating disorders and signal transmission of the orexinorghetic system of the hypothalamus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obesity" title="obesity">obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=endocrinology" title=" endocrinology"> endocrinology</a>, <a href="https://publications.waset.org/abstracts/search?q=hypothalamus" title=" hypothalamus"> hypothalamus</a>, <a href="https://publications.waset.org/abstracts/search?q=overweight" title=" overweight"> overweight</a> </p> <a href="https://publications.waset.org/abstracts/161375/the-role-of-hypothalamus-mediators-in-energy-imbalance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161375.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">9</span> A Methodology for Characterising the Tail Behaviour of a Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serge%20Provost">Serge Provost</a>, <a href="https://publications.waset.org/abstracts/search?q=Yishan%20Zang"> Yishan Zang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Following a review of various approaches that are utilized for classifying the tail behavior of a distribution, an easily implementable methodology that relies on an arctangent transformation is presented.

The resulting categories enable one to classify distributional tails as distinctly short, short, nearly medium, medium, extended medium and somewhat long, providing that at least two moments exist. Distributions possessing a single moment are said to be long tailed while those failing to have any finite moments are classified as having an extremely long tail.

All Buddha and Bodhisattvas pay great respect to the Earth Store Bodhisattva because He vowed that He would not become Buddha until the hell is empty, and He would only achieve Bodhi until all sentient beings have been saved. The aim of this study is to investigate Venerable Master Di-Chiao, who actualizes the Buddha’s teaching and practices the Earth Store Bodhisattva’s compassion and apply them to help people. In fact, she has integrated her learning to teach people how to eliminate their karmic suffering with her close attention and full effort, even though she would be hurt all over or she had to sacrifice her own life. This qualitative research gathers data in terms of a field study, including an interview with Venerable Master Di-Chiao, a book about the Master and three books about true stories of people saved by the Master, and about 300 online feedbacks from her disciples and followers explaining how they were helped by the Master through their difficulties, together with a year-long observation at the Dharma services held in Taipei Di-Zang Temple. This article is divided into four parts: The first part depicts Master Di-Chiao’s original intent of being a nun and her three-step-one-bow pilgrimage experience around Taiwan. Part two illustrates the invitation of the Master’s being the Abbess of Tsiang-Te Temple, which was designated by Bodhisattva Avalokitesvara in a manager’s dream of the temple, and many unexpected difficulties ahead of the cultivation in the Master’s Buddha Path. In addition to maintenance of Tsiang-Te Temple, the third part will discuss the purpose of founding Taipei Di-Zang Temple, in which the Master always tries her best with various methods to cultivate good seeds for her disciples and followers and watches out for their karma and does her utmost effort to help them overcome it. The final part will briefly explain the Three Buddhalization: Buddhist wedding, Buddhist prenatal education and Buddhist family, which the Master has been advocating and considers them the essence of constructing a harmonious society and having a meaningful and enlightening life. Extraordinary results of practicing the Three Buddhalization will be given. Findings show that Master’s Di-Chiao’s actualization of Buddha’s teaching and Bodhisattva’s compassion is incredibly amazing and powerful, and she has helped countless people to conquer their difficulties and purify their evil habits. With the Master’s assistance and their hardworking and faith to the Master’s teaching, some of her disciples and followers have gone to the Maitreya Inside Realm, where the future Buddha has resided, and continue their cultivation. True stories will be presented to illuminate the incredibility of the Master’s compassion, her brevity and perseverance in the course of the Buddhahood. Venerable Master Di-Chiao is the embodiment of the Earth Store Bodhisattva for her disciples and followers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compassion" title="compassion">compassion</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20Earth%20Store%20Bodhisattva" title=" the Earth Store Bodhisattva"> the Earth Store Bodhisattva</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20Buddhalization" title=" three Buddhalization"> three Buddhalization</a>, <a href="https://publications.waset.org/abstracts/search?q=venerable%20Master%20Di-Chiao" title=" venerable Master Di-Chiao"> venerable Master Di-Chiao</a> </p> <a href="https://publications.waset.org/abstracts/95381/master-di-chiao-a-great-practitioner-of-earth-store-bodhisattvas-compassion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95381.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">136</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">7</span> Garden City in the Age of ICT: A Case Study of Dali</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luojie%20Tang">Luojie Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Libin%20Ouyang"> Libin Ouyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yihang%20Gao"> Yihang Gao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The natural landscape and urban-rural structure, with their attractiveness in the Dali area around Erhai Lake, exhibit striking similarities with Howard's Garden City. With the emergence of the unique phenomenon of the first large-scale gathering of digital nomads in China in Dali, an analysis of Dali's natural, economic, and cultural representations and structures reveals that the Garden City model can no longer fully explain the current overall human living environment in Dali. By interpreting the bottom-up local construction process in Dali based on landscape identity, the transformation of production and lifestyle under new technologies such as ICT(Information and Communication Technology), and the values and lifestyle reshaping embodied in the "reverse urbanization" phenomenon of the middle class in Dali, it is believed that Dali has moved towards a "contemporary garden city influenced by new technology." The article summarizes the characteristics and connotations of this Garden City and provides corresponding strategies for its continued healthy development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dali" title="dali">dali</a>, <a href="https://publications.waset.org/abstracts/search?q=ICT" title=" ICT"> ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=rural-urban%20relationship" title=" rural-urban relationship"> rural-urban relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=garden%20city%20model" title=" garden city model"> garden city model</a> </p> <a href="https://publications.waset.org/abstracts/165369/garden-city-in-the-age-of-ict-a-case-study-of-dali" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165369.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> A Study on the Nostalgia Contents Analysis of Hometown Alumni in the Online Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heejin%20Yun">Heejin Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Juanjuan%20Zang"> Juanjuan Zang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to analyze the text terms posted on an online community of people from the same hometown and to understand the topic and trend of nostalgia composed online.

As a result, online community texts means that just defining nostalgia as ‘a mind longing for hometown’ is not an enough explanation. Second, texts composed online have abstractness rather than persons’ individual stories. This study figured out the relationship that had the most critical and closest mutual association among the terms that constituted nostalgia through literature research and association rule concerning nostalgia.

It follows from Sklar's theorem that the joint distribution function of a multidimensional random vector can be expressed in terms of its associated copula and marginals. Since marginal distributions can easily be determined by making use of a variety of techniques, we address the problem of securing the distribution of the copula. This will be done by using several approaches. For example, we will obtain bivariate least-squares approximations of the empirical copulas, modify the kernel density estimation technique and propose a criterion for selecting appropriate bandwidths, differentiate linearized empirical copulas, secure Bernstein polynomial approximations of suitable degrees, and apply a corollary to Sklar's result. Illustrative examples involving actual observations will be presented. The proposed methodologies will as well be applied to a sample generated from a known copula distribution in order to validate their effectiveness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copulas" title="copulas">copulas</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernstein%20polynomial%20approximation" title=" Bernstein polynomial approximation"> Bernstein polynomial approximation</a>, <a href="https://publications.waset.org/abstracts/search?q=least-squares%20polynomial%20approximation" title=" least-squares polynomial approximation"> least-squares polynomial approximation</a>, <a href="https://publications.waset.org/abstracts/search?q=kernel%20density%20estimation" title=" kernel density estimation"> kernel density estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20approximation" title=" density approximation"> density approximation</a> </p> <a href="https://publications.waset.org/abstracts/170324/nonparametric-copula-approximations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170324.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">73</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">4</span> Survey and Analysis of the Operational Dilemma of the Existing Used Clothes Recycling Model in the Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qiaohui%20Zhong">Qiaohui Zhong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yiqi%20Kuang"> Yiqi Kuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wanxun%20Cai"> Wanxun Cai</a>, <a href="https://publications.waset.org/abstracts/search?q=Libin%20Huang"> Libin Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a community public facility, the popularity and perfection of old clothes recycling products directly affect people's impression of the whole city, which is related to the happiness index of residents' lives and is of great significance to the construction of eco-civilized cities and the realization of sustainable urban development. At present, China's waste clothing is characterized by large production and a high utilization rate, but the current rate of old clothes recycling is low, and the ‘one-size-fits-all’ recycling model makes people's motivation for old clothes recycling low, and old clothes recycling is in a dilemma. Based on the two online and offline recycling modes of old clothes recycling in Chinese communities, this paper conducts an in-depth survey on the public, operators, and regulators from the aspects of activity scene analysis, crowd attributes analysis, and community space analysis summarizes the difficulties of old clothes recycling for the public - nowhere to recycle, inconvenient to recycle and unwilling to recycle, and analyzes the factors that lead to these difficulties, and gives a solution with foreign experience to solve these problems. It also analyzes the factors that lead to these difficulties and gives targeted suggestions in combination with foreign experience, exploring and proposing a set of appropriate modern old-clothes recycling modes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community" title="community">community</a>, <a href="https://publications.waset.org/abstracts/search?q=old%20clothes%20recycling" title=" old clothes recycling"> old clothes recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20mode" title=" recycling mode"> recycling mode</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20urban%20development" title=" sustainable urban development"> sustainable urban development</a> </p> <a href="https://publications.waset.org/abstracts/185863/survey-and-analysis-of-the-operational-dilemma-of-the-existing-used-clothes-recycling-model-in-the-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185863.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">46</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">3</span> Probabilistic Fracture Evaluation of Reactor Pressure Vessel Subjected to Pressurized Thermal Shock</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianguo%20Chen">Jianguo Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Fenggang%20Zang"> Fenggang Zang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Yang"> Yu Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Liangang%20Zheng"> Liangang Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reactor Pressure Vessel (RPV) is an important security barrier in nuclear power plant. Crack like defects may be produced on RPV during the whole operation lifetime due to the harsh operation condition and irradiation embrittlement. During the severe loss of coolant accident, thermal shock happened as the injection of emergency cooling water into RPV, which results in re-pressurization of the vessel and very high tension stress on the vessel wall, this event called Pressurized Thermal Shock (PTS). Crack on the vessel wall may propagate even penetrate the vessel, so the safety of the RPV would undergo great challenge. Many assumptions in structure integrity evaluation make the result of deterministic fracture mechanics very conservative, which affect the operation lifetime of the plant. Actually, many parameters in the evaluation process, such as fracture toughness and nil-ductility transition temperature, have statistical distribution characteristics. So it is necessary to assess the structural integrity of RPV subjected to PTS event by means of Probabilistic Fracture Mechanics (PFM). Structure integrity evaluation methods of RPV subjected to PTS event are summarized firstly, then evaluation method based on probabilistic fracture mechanics are presented by considering the probabilistic characteristics of material and structure parameters. A comprehensive analysis example is carried out at last. The results show that the probability of crack penetrates through wall increases gradually with the growth of fast neutron irradiation flux. The results give advice for reactor life extension. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fracture%20toughness" title="fracture toughness">fracture toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=integrity%20evaluation" title=" integrity evaluation"> integrity evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=pressurized%20thermal%20shock" title=" pressurized thermal shock"> pressurized thermal shock</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20fracture%20mechanics" title=" probabilistic fracture mechanics"> probabilistic fracture mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20pressure%20vessel" title=" reactor pressure vessel"> reactor pressure vessel</a> </p> <a href="https://publications.waset.org/abstracts/53569/probabilistic-fracture-evaluation-of-reactor-pressure-vessel-subjected-to-pressurized-thermal-shock" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53569.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Land Layout and Urban Design of New Cities in Underdeveloped Areas of China: A Case Study of Xixian New Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Libin%20Ouyang">Libin Ouyang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> China has experienced a very fast urbanization process in the past two decades. Due to the uncoordinated characteristics of regional development in China, a large number of people from rural areas or small towns have flooded into regional central cities, which are building new cities around them due to the shortage of construction land or the need for urban development. However, the construction of some new cities has not achieved the expected effect, the absorption capacity of industry and population is limited, and the phenomenon of capital and land waste is obvious. This paper takes the Xixian New Area in Shaanxi Province, an inland region in Northwest China, as an example, and tries to analyse the reasons for the lack of vitality in the current situation of the Xixian New Area from the perspective of site layout and urban design, analyses the practical experience of the construction of new city cores in developed countries and regions, and studies how to optimise at the level of site layout planning and urban design to improve the vitality and attractiveness of the new city, decongest the population of large cities, effectively solve the problems of large cities, and promote The study will also examine how to optimise land use planning and urban design to enhance the vitality and attractiveness of new cities, relieve the population of large cities, effectively solve the problems of large cities and promote sustainable development of new cities. The study can serve as a reference for urban planners and policy makers, provide theoretical assistance for new city construction in other less developed regions of China, and provide some case references for urban construction in other developing countries undergoing rapid urbanisation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20city" title="new city">new city</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use%20layout" title=" land use layout"> land use layout</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20design" title=" urban design"> urban design</a>, <a href="https://publications.waset.org/abstracts/search?q=attraction" title=" attraction"> attraction</a> </p> <a href="https://publications.waset.org/abstracts/165771/land-layout-and-urban-design-of-new-cities-in-underdeveloped-areas-of-china-a-case-study-of-xixian-new-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Analysis of Vortex-Induced Vibration Characteristics for a Three-Dimensional Flexible Tube</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhipeng%20Feng">Zhipeng Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Huanhuan%20Qi"> Huanhuan Qi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pingchuan%20Shen"> Pingchuan Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Fenggang%20Zang"> Fenggang Zang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yixiong%20Zhang"> Yixiong Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical simulations of vortex-induced vibration of a three-dimensional flexible tube under uniform turbulent flow are calculated when Reynolds number is 1.35×10<sup>4</sup>. In order to achieve the vortex-induced vibration, the three-dimensional unsteady, viscous, incompressible Navier-Stokes equation and LES turbulence model are solved with the finite volume approach, the tube is discretized according to the finite element theory, and its dynamic equilibrium equations are solved by the Newmark method. The fluid-tube interaction is realized by utilizing the diffusion-based smooth dynamic mesh method. Considering the vortex-induced vibration system, the variety trends of lift coefficient, drag coefficient, displacement, vertex shedding frequency, phase difference angle of tube are analyzed under different frequency ratios. The nonlinear phenomena of locked-in, phase-switch are captured successfully. Meanwhile, the limit cycle and bifurcation of lift coefficient and displacement are analyzed by using trajectory, phase portrait, and Poincaré sections. The results reveal that: when drag coefficient reaches its minimum value, the transverse amplitude reaches its maximum, and the “lock-in” begins simultaneously. In the range of lock-in, amplitude decreases gradually with increasing of frequency ratio. When lift coefficient reaches its minimum value, the phase difference undergoes a suddenly change from the “out-of-phase” to the “in-phase” mode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vortex%20induced%20vibration" title="vortex induced vibration">vortex induced vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=limit%20cycle" title=" limit cycle"> limit cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=LES" title=" LES"> LES</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a> </p> <a href="https://publications.waset.org/abstracts/41577/analysis-of-vortex-induced-vibration-characteristics-for-a-three-dimensional-flexible-tube" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41577.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">281</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
