In this study, the design process involved parametric geometry modeling in CAD, MATLAB coding of performance prediction and 2D star grain ignition experiment. The 2D star grain burnback achieved by creating new surface via each web increment and calculating geometrical properties at each step. The 2D star grain is further modified to burn as a tapered 3D star grain. Zero dimensional method used to calculate the internal ballistic performance. Experimental and theoretical results were compared in order to validate the performance prediction of the solid rocket motor. The results show that the usage of 3D grain geometry will decrease the pressure inside the combustion chamber and enhance the volumetric loading ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=burnback%20analysis" title="burnback analysis">burnback analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rocket%20motor" title=" rocket motor"> rocket motor</a>, <a href="https://publications.waset.org/abstracts/search?q=star%20grain" title=" star grain"> star grain</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20dimensional%20grains" title=" three dimensional grains"> three dimensional grains</a> </p> <a href="https://publications.waset.org/abstracts/82081/design-and-burnback-analysis-of-three-dimensional-modified-star-grain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82081.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">245</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">246</span> The Existence of Field Corn Networks on the Thailand-Burma Border under the Patron-Client Contract Farming System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kettawa%20Boonprakarn">Kettawa Boonprakarn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jedsarid%20Sangkaphan"> Jedsarid Sangkaphan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bejapornd%20Deekhuntod"> Bejapornd Deekhuntod</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuntharat%20Suriyo"> Nuntharat Suriyo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to investigate the existence of field corn networks on the Thailand-Burma border under the patron-client contract farming system. The data of this qualitative study were collected through in-depth interviews with nine key informants. The results of the study revealed that the existence of the field corn networks was associated with the relationship where farmers had to share their crops with protectors in the areas under the influence of the KNU (Karen National Union) and the DKBA (Democratic Karen Buddhist Army) or Burmese soldiers. A Mae Liang, the person who starts a network has a connection with a Thaokae, Luk Rai Hua Chai or the head of a group of farmers, and farmers. They are under the patron-client system with trust and loyalty that enable the head of the group and the farmers in the Burma border side to remain under the same Mae Liang even though the business has been passed down to later generations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=existence" title="existence">existence</a>, <a href="https://publications.waset.org/abstracts/search?q=field-corn%20networks" title=" field-corn networks"> field-corn networks</a>, <a href="https://publications.waset.org/abstracts/search?q=patron-client%20system" title=" patron-client system"> patron-client system</a>, <a href="https://publications.waset.org/abstracts/search?q=contract%20farming" title=" contract farming"> contract farming</a> </p> <a href="https://publications.waset.org/abstracts/3431/the-existence-of-field-corn-networks-on-the-thailand-burma-border-under-the-patron-client-contract-farming-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3431.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">270</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">245</span> Sensitivity and Uncertainty Analysis of One Dimensional Shape Memory Alloy Constitutive Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20B.%20M.%20Rezaul%20Islam">A.

Their thermomechanical behaviors are modeled by numerous researchers using microscopic thermodynamic and macroscopic phenomenological point of view. Tanaka, Liang-Rogers and Ivshin-Pence models are some of the most popular SMA macroscopic phenomenological constitutive models. They describe SMA behavior in terms of stress, strain and temperature. These models involve material parameters and they have associated uncertainty present in them. At different operating temperatures, the uncertainty propagates to the output when the material is subjected to loading followed by unloading. The propagation of uncertainty while utilizing these models in real-life application can result in performance discrepancies or failure at extreme conditions. To resolve this, we used probabilistic approach to perform the sensitivity and uncertainty analysis of Tanaka, Liang-Rogers, and Ivshin-Pence models. Sobol and extended Fourier Amplitude Sensitivity Testing (eFAST) methods have been used to perform the sensitivity analysis for simulated isothermal loading/unloading at various operating temperatures. As per the results, it is evident that the models vary due to the change in operating temperature and loading condition. The average and stress-dependent sensitivity indices present the most significant parameters at several temperatures. This work highlights the sensitivity and uncertainty analysis results and shows comparison of them at different temperatures and loading conditions for all these models. The analysis presented will aid in designing engineering applications by eliminating the probability of model failure due to the uncertainty in the input parameters. Thus, it is recommended to have a proper understanding of sensitive parameters and the uncertainty propagation at several operating temperatures and loading conditions as per Tanaka, Liang-Rogers, and Ivshin-Pence model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constitutive%20models" title="constitutive models">constitutive models</a>, <a href="https://publications.waset.org/abstracts/search?q=FAST%20sensitivity%20analysis" title=" FAST sensitivity analysis"> FAST sensitivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sobol" title=" sobol"> sobol</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20alloy" title=" shape memory alloy"> shape memory alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20analysis" title=" uncertainty analysis"> uncertainty analysis</a> </p> <a href="https://publications.waset.org/abstracts/117933/sensitivity-and-uncertainty-analysis-of-one-dimensional-shape-memory-alloy-constitutive-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117933.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">144</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">244</span> UCP1 Regulates Cardiolipin Metabolism and Mediates Mitochondrial Homeostasis Maintenance of ANXA1 in Diabetic Nephropathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zi-Han%20Li">Zi-Han Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%20Fang"> Lu Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Wu"> Liang Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Yuan%20Chang"> Dong-Yuan Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Manyuan%20Dong"> Manyuan Dong</a>, <a href="https://publications.waset.org/abstracts/search?q=Liang%20Ji"> Liang Ji</a>, <a href="https://publications.waset.org/abstracts/search?q=Qi%20Zhang"> Qi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Hui%20Zhao"> Ming-Hui Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Sydney%20C.%20W.%20Tang"> Sydney C.

Here, we identified uncoupling protein 1 (UCP1), an inner membrane protein of mitochondria, as a key to mitochondrial homeostasis improved by ANXA1.

After extensive literature study and field research, it was found that there are a few risk assessment methods for coal mined gob pipelines, and there is a lack of data on the gob sites. Therefore, the fuzzy comprehensive evaluation method is widely used based on expert opinions. However, the subjective opinions or lack of experience of individual experts may lead to inaccurate evaluation results. Hence the accuracy of the results needs to be further improved. This paper presents a comprehensive approach to achieve this purpose by combining bow-tie model and cloud inference. The specific evaluation process is as follows: First, a bow-tie model composed of a fault tree and an event tree is established to graphically illustrate the probability and consequence indicators of pipeline failure. Second, the interval estimation method can be scored in the form of intervals to improve the accuracy of the results, and the censored mean algorithm is used to remove the maximum and minimum values of the score to improve the stability of the results. The golden section method is used to determine the weight of the indicators and reduce the subjectivity of index weights. Third, the failure probability and failure consequence scores of the pipeline are converted into three numerical features by using cloud inference. The cloud inference can better describe the ambiguity and volatility of the results which can better describe the volatility of the risk level. Finally, the cloud drop graphs of failure probability and failure consequences can be expressed, which intuitively and accurately illustrate the ambiguity and randomness of the results. A case study of a coal mine gob pipeline carrying natural gas has been investigated to validate the utility of the proposed method. The evaluation results of this case show that the probability of failure of the pipeline is very low, the consequences of failure are more serious, which is consistent with the reality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bow-tie%20model" title="bow-tie model">bow-tie model</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20gas%20pipeline" title=" natural gas pipeline"> natural gas pipeline</a>, <a href="https://publications.waset.org/abstracts/search?q=coal%20mine%20gob" title=" coal mine gob"> coal mine gob</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20inference" title=" cloud inference"> cloud inference</a> </p> <a href="https://publications.waset.org/abstracts/98476/risk-assessment-of-natural-gas-pipelines-in-coal-mined-gobs-based-on-bow-tie-model-and-cloud-inference" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98476.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">250</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">239</span> The Antitumor Activity of Eu (III) and Er (III) Complexes of 3 - (1H-Benzimidazol-2-Yl) - 6 - Methyl - 2 (1H) - Quinolinone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xing%20Lu">Xing Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-ming%20Wu"> Yi-ming Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan-hong%20Zhu"> Yan-hong Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen-feng%20Chen"> Zhen-feng Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Liang"> Hong Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Peng"> Yan Peng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> [Eu(BMQ)2(NO3)3(CH3OH)(H2O)] (1),and [Er(BMQ)2(NO3)3(CH3OH)(H2O)] (2),were synthesized.

The controller employs the concept of duty ratio on the electric valve control, which could make full use of the cooling and dehumidifying capacity of the FCU when the valve is off. The traditional control method and its limitations are analyzed. The hardware and software design processes are introduced in detail. The experimental results show that the proposed method is more energy efficient compared to the traditional controlling strategy. Furthermore, a more comfortable room condition could be achieved by the proposed method. The proposed low-cost FCU fuzzy controller deserves to be widely used in engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fan%20coil%20unit" title="fan coil unit">fan coil unit</a>, <a href="https://publications.waset.org/abstracts/search?q=duty%20ratio" title=" duty ratio"> duty ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20controller" title=" fuzzy controller"> fuzzy controller</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment" title=" experiment"> experiment</a> </p> <a href="https://publications.waset.org/abstracts/52767/design-and-implementation-of-a-fan-coil-unit-controller-based-on-the-duty-ratio-fuzzy-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52767.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">339</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">226</span> Dynamic Analysis of Differential Systems with Infinite Memory and Damping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kun-Peng%20Jin">Kun-Peng Jin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Liang"> Jin Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ti-Jun%20Xiao"> Ti-Jun Xiao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we are concerned with the dynamic behaviors of solutions to some coupled systems with infinite memory, which consist of two partial differential equations where only one partial differential equation has damping.

By using the theory of operator semigroups, we give wellposedness results for the Cauchy problem for these coupled systems. Then, with the help of some auxiliary functions and lemmas, which are specially designed for overcoming difficulties in the proof, we show that the solutions of the coupled systems decay to zero in a strong way under a few basic conditions.

The effects of partial shadow on the energy yield of conventional mono-crystalline and multi-crystalline PV modules have been researched for a long time. With deployment of new thin-film solar PV modules in the market, it is important to understand the performance of new PV modules operating under the partial shadow in the tropical zone.

This survey is intended to raise greater awareness and discussion about the use and effect of these displays in public areas. Through this survey, we have been able to distill some lessons of what is good, bad, and ugly about some current examples of media displays used in a city that is transitioning into becoming a modern one and one that is located in one of the fastest growing areas in Asia.

Even the edge directions can determine the controllability of complex networks. Obviously, for a given network, we wish to design its edge directions that make this network approach the optimal controllability. In this work, we firstly introduce two methods to enhance network by assigning edge directions. However, these two methods could not completely mitigate the negative effects of inaccessibility and dilations. Thus, to approach the optimal network controllability, the edge directions must mitigate the negative effects of inaccessibility and dilations as much as possible. Finally, we propose the edge direction for optimal controllability. The optimal method has been found to be successfully useful on real-world and synthetic networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20network" title="complex network">complex network</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamics" title=" dynamics"> dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20control" title=" network control"> network control</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/103008/designing-directed-network-with-optimal-controllability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103008.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">185</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">220</span> The Effects of Three Leadership Styles on Individual Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leilei%20Liang">Leilei Liang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leadership is commonly classified as formal leadership and informal leadership, which ignores and neglects the effects of 3rd type leadership.

The analytical results provide strong evidence for two of the three hypotheses, which demonstrate the positive correlation between formal leadership and individual performance and the negative relationship between 3rd type leadership and individual performance.
