The article uses the methods of comparative case analysis and process tracing to investigate the prospect theory鈥檚 fundamental arguments. Through evidence derived from existing primary and secondary sources, this paper argues that both former U.S. President Bush and Russian President Putin viewed their situations as a domain of loss and made risky decisions to prevent further deterioration, which attests the arguments of the prospect theory. After the two case studies, this article also discusses how the prospect theory could be used in analyzing the decision-making process that led to the current Russia-Ukraine War. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20prospect%20theory" title="the prospect theory">the prospect theory</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20relations" title=" international relations"> international relations</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20first%20gulf%20war" title=" the first gulf war"> the first gulf war</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20crimea%20crisis" title=" the crimea crisis"> the crimea crisis</a> </p> <a href="https://publications.waset.org/abstracts/155416/logic-of-the-prospect-theory-the-decision-making-process-of-the-first-gulf-war-and-the-crimean-annexation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155416.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">125</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">817</span> Satisfaction Evaluation on the Fundamental Public Services for a Large-Scale Indemnificatory Residential Community: A Case Study of Nanjing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dezhi%20Li">Dezhi Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng%20Cui"> Peng Cui</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Zhang"> Bo Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tengyuan%20Chang"> Tengyuan Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to solve the housing problem for the low-income families, the construction of affordable housing is booming in China.

Informatics applying a range of mathematical, statistical and rule-based approaches can be used to reveal important information on demand from the available data provided at second, minute or hourly intervals. This study aims to combine these two concepts to improve the current water end use disaggregation problem through applying a wide range of most advanced pattern recognition techniques to analyse the concurrent high-resolution water-energy consumption data. The obtained results have shown that recognition accuracies of all end-uses have significantly increased, especially for mechanised categories, including clothes washer, dishwasher and evaporative air cooler where over 95% of events were correctly classified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20learning%20network" title="deep learning network">deep learning network</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20metering" title=" smart metering"> smart metering</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20end%20use" title=" water end use"> water end use</a>, <a href="https://publications.waset.org/abstracts/search?q=water-energy%20data" title=" water-energy data"> water-energy data</a> </p> <a href="https://publications.waset.org/abstracts/75514/water-end-use-classification-with-contemporaneous-water-energy-data-and-deep-learning-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75514.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">306</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">814</span> Refractometric Optical Sensing by Using Photonics Mach鈥揨ehnder Interferometer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gong%20Zhang">Gong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Cai"> Hong Cai</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Dong"> Bin Dong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jifang%20Tao"> Jifang Tao</a>, <a href="https://publications.waset.org/abstracts/search?q=Aiqun%20Liu"> Aiqun Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dim-Lee%20Kwong"> Dim-Lee Kwong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuandong%20Gu"> Yuandong Gu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An on-chip refractive index sensor with high sensitivity and large measurement range is demonstrated in this paper. The sensing structures are based on Mach-Zehnder interferometer configuration, built on the SOI substrate. The wavelength sensitivity of the sensor is estimated to be 3129 nm/RIU. Meanwhile, according to the interference pattern period changes, the measured period sensitivities are 2.9 nm/RIU (TE mode) and 4.21 nm/RIU (TM mode), respectively. As such, the wavelength shift and the period shift can be used for fine index change detection and larger index change detection, respectively. Therefore, the sensor design provides an approach for large index change measurement with high sensitivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mach-Zehnder%20interferometer" title="Mach-Zehnder interferometer">Mach-Zehnder interferometer</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title=" nanotechnology"> nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=refractive%20index%20sensing" title=" refractive index sensing"> refractive index sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=sensors" title=" sensors"> sensors</a> </p> <a href="https://publications.waset.org/abstracts/37878/refractometric-optical-sensing-by-using-photonics-mach-zehnder-interferometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37878.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">445</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">813</span> Evaluating Classification with Efficacy Metrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guofan%20Shao">Guofan Shao</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Tang"> Lina Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao%20Zhang"> Hao Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The values of image classification accuracy are affected by class size distributions and classification schemes, making it difficult to compare the performance of classification algorithms across different remote sensing data sources and classification systems. Based on the term efficacy from medicine and pharmacology, we have developed the metrics of image classification efficacy at the map and class levels. The novelty of this approach is that a baseline classification is involved in computing image classification efficacies so that the effects of class statistics are reduced. Furthermore, the image classification efficacies are interpretable and comparable, and thus, strengthen the assessment of image data classification methods. We use real-world and hypothetical examples to explain the use of image classification efficacies. The metrics of image classification efficacy meet the critical need to rectify the strategy for the assessment of image classification performance as image classification methods are becoming more diversified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy%20assessment" title="accuracy assessment">accuracy assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy" title=" efficacy"> efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20classification" title=" image classification"> image classification</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/142555/evaluating-classification-with-efficacy-metrics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142555.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">211</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">812</span> Several Spectrally Non-Arbitrary Ray Patterns of Order 4</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ling%20Zhang">Ling Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Liu"> Feng Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A matrix is called a ray pattern matrix if its entries are either 0 or a ray in complex plane which originates from 0.

Due to the interlayered porous structure of KC, we achieved a perfect association between ZnO NPs and KC. SEM image showed the irregular morphology of ZnO NPs, while ZnO/KC NCs were predominately round-shaped. Moreover, in both cases, NPs were present in dispersed and agglomerated forms with an average particle size way below 100 nm. The results acquired from photodegradation analyses showed that ZnO NPs and ZnO/KC NCs degraded about 82% and 99% of MR under UV light in a short irradiation time within 10 min. The recovered and re-recovered ZnO NPs and ZnO/KC NCs were also considerably photodegraded MR in an aqueous medium. The same NPs also exhibit promising bioactivities against two pathogenic bacteria, i.e., Citrobacter and Providencia. ZnO/KC NCs' antioxidant activity reached a reasonable 70% compared to the 88% activity of the standard ascorbic acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title="nanoparticles">nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalyst" title=" photocatalyst"> photocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=photodegradation" title=" photodegradation"> photodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title=" zinc oxide"> zinc oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=methyl%20red" title=" methyl red"> methyl red</a> </p> <a href="https://publications.waset.org/abstracts/167979/efficient-photodegradation-of-methyl-red-dye-by-kaolin-clay-supported-zinc-oxide-nanoparticles-with-their-antibacterial-and-antioxidant-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167979.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">810</span> Effects of Hydrogen-Ion Irritation on the Microstructure and Hardness of Fe-0.2wt.%V Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Zhang">Jing Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongqin%20Chang"> Yongqin Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongwei%20Wang"> Yongwei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaolin%20Li"> Xiaolin Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaoning%20Jiang"> Shaoning Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Farong%20Wan"> Farong Wan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20Long"> Yi Long</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microstructural and hardening changes of Fe-0.2wt.%V alloy and pure Fe irradiated with 100 keV hydrogen ions at room temperature were investigated. It was found that dislocation density varies dramatically after irradiation, ranging from dislocation free to dense areas with tangled and complex dislocation configuration. As the irradiated Fe-0.2wt.%V samples were annealed at 773 K, the irradiation-induced dislocation loops disappear, while many small precipitates with enriched C distribute in the matrix. Some large precipitates with enriched V were also observed. The hardness of Fe-0.2wt.%V alloy and pure Fe increases after irradiation, which ascribes to the formation of dislocation loops in the irradiated specimens. Compared with pure Fe, the size of the irradiation-introduced dislocation loops in Fe-0.2wt.%V alloy decreases and the density increases, the change of the hardness also decreases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=irradiation" title="irradiation">irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe-0.2wt.%25V%20alloy" title=" Fe-0.2wt.%V alloy"> Fe-0.2wt.%V alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructures" title=" microstructures"> microstructures</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a> </p> <a href="https://publications.waset.org/abstracts/30363/effects-of-hydrogen-ion-irritation-on-the-microstructure-and-hardness-of-fe-02wtv-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30363.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">386</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">809</span> A Study of the Assistant Application for Tourists Taking Metros</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anqi%20Wang">Anqi Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Linye%20Zhang"> Linye Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the proliferation and development of mobile devices, various mobile apps have appeared to satisfy people’s needs.

The mechanical properties of Ni-diamond composite coating can be promoted by the high incorporation and uniform distribution of diamond particles in the nickel matrix, while the distribution features of particles are affected by electrodeposition process parameters, especially the additives in the plating bath. Glycine has been utilized as an organic additive during the preparation of pure nickel coating, which can effectively increase the coating hardness. Nevertheless, to author鈥檚 best knowledge, no research about the effects of glycine on the Ni-diamond co-deposition has been reported. In this work, the diamond reinforced Ni nanocomposite coatings were fabricated by a co-electrodeposition technique from a modified Watt鈥檚 type bath in the presence of glycine. After preparation, the SEM morphology of the composite coatings was observed combined with energy dispersive X-ray spectrometer, and the diamond incorporation was analyzed. The surface morphology and roughness were obtained by a three-dimensional profile instrument. 3D-Debye rings formed by XRD were analyzed to characterize the nickel grain size and orientation in the coatings. The average coating thickness was measured by a digital micrometer to deduce the deposition rate. The microhardness was tested by automatic microhardness tester. The friction coefficient and wear volume were measured by reciprocating wear tester to characterize the coating wear resistance and cutting performance. The experimental results confirmed that the presence of glycine effectively improved the surface morphology and roughness of the composite coatings. By optimizing the glycine concentration, the incorporation of diamond particles was increased, while the nickel grain size decreased with increasing glycine. The hardness of the composite coatings was increased as the glycine concentration increased. The friction and wear properties were evaluated as the glycine concentration was optimized, showing a decrease in the wear volume. The wear resistance of the composite coatings increased as the glycine content was increased to an optimum value, beyond which the wear resistance decreased. Glycine complexation contributed to the nickel grain refinement and improved the diamond dispersion in the coatings, both of which made a positive contribution to the amount and uniformity of embedded diamond particles, thus enhancing the microhardness, reducing the friction coefficient, and hence increasing the wear resistance of the composite coatings. Therefore, additive glycine can be used during the co-deposition process to improve the mechanical properties of protective coatings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=co-electrodeposition" title="co-electrodeposition">co-electrodeposition</a>, <a href="https://publications.waset.org/abstracts/search?q=glycine" title=" glycine"> glycine</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni-diamond%20nanocomposite%20coatings" title=" Ni-diamond nanocomposite coatings"> Ni-diamond nanocomposite coatings</a> </p> <a href="https://publications.waset.org/abstracts/105213/mechanical-properties-of-diamond-reinforced-ni-nanocomposite-coatings-made-by-co-electrodeposition-with-glycine-as-additive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105213.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">125</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">806</span> Plantation Forests Height Mapping Using Unmanned Aerial System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shiming%20Li">Shiming Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingwang%20Liu"> Qingwang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Honggan%20Wu"> Honggan Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianbing%20Zhang"> Jianbing Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plantation forests are useful for timber production, recreation, environmental protection and social development.

It is seen that the current design codes of practice cannot accurately predict the shear strength of seismically designed knee joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=large-scale%20tests" title="large-scale tests">large-scale tests</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20beam-column%20knee%20joints" title=" RC beam-column knee joints"> RC beam-column knee joints</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strength" title=" shear strength"> shear strength</a> </p> <a href="https://publications.waset.org/abstracts/59153/effect-of-horizontal-joint-reinforcement-on-shear-behaviour-of-rc-knee-connections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59153.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">249</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">798</span> Electrokinetic Remediation of Uranium Contaminated Soil by Ion Exchange Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20H.%20Shi">Z.

The electrokinetic process is one of the most promising remediation techniques for sludge, sediment, and saturated or unsaturated soils contaminated with heavy metals and radionuclides. However, secondary waste is a major concern for soil contaminated with nuclides. To minimize the generation of secondary wastes, this study used the anion and cation exchange membranes to improve the performance of the experimental apparatus. Remediation experiments of uranium-contaminated soil were performed with different agents. The results show that using acetic acid and EDTA as chelating agents clearly enhances the migration ability of the uranium. The ion exchange membranes (IEMs) used in the experiments not only reduce secondary wastes, but also, keep the soil pH stable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrokinetic%20remediation" title="electrokinetic remediation">electrokinetic remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange%20membranes" title=" ion exchange membranes"> ion exchange membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a> </p> <a href="https://publications.waset.org/abstracts/48962/electrokinetic-remediation-of-uranium-contaminated-soil-by-ion-exchange-membranes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48962.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">352</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">797</span> Design of Jumping Structure of Spherical Robot Based on Archimedes' Helix</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Zijian">Zhang Zijian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, spherical robots have played an important role in many fields, but the insufficient ability of obstacle surmounting limits their wider application fields. To solve this problem, a jumping system of a spherical robot is designed based on Archimedes helix. The jumping system of the robot utilizes the characteristics of Archimedes helix and isovelocity helix to achieve constant speed and stable contraction, which ensures the stability of the system. Also, the jumping action of the robot is realized by instantaneous release of elastic potential energy. In order to verify the effectiveness of the jumping system, we designed a spherical robot and its jumping system. The experimental results show that the jumping system has the advantages of light weight, small size, high energy conversion efficiency, and can realize the spherical jumping function. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hopping%20mechanism" title="hopping mechanism">hopping mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=Archimedes%27%20Helix" title=" Archimedes' Helix"> Archimedes' Helix</a>, <a href="https://publications.waset.org/abstracts/search?q=hopping%20robot" title=" hopping robot"> hopping robot</a>, <a href="https://publications.waset.org/abstracts/search?q=spherical%20robot" title=" spherical robot"> spherical robot</a> </p> <a href="https://publications.waset.org/abstracts/106835/design-of-jumping-structure-of-spherical-robot-based-on-archimedes-helix" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106835.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">135</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">796</span> Novel Stator Structure Switching Flux Permanent Magnet Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mengjie%20Shen">Mengjie Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianhua%20Wu"> Jianhua Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun%20Gan"> Chun Gan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lifeng%20Zhang"> Lifeng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingguo%20Sun"> Qingguo Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Switching flux permanent magnet (SFPM) motor has doubly salient structure which lead to high torque ripple, and also has cogging torque as a permanent magnet motor.

PR review is an essential part of open source software developments for maintaining the quality of software. Matching a new PR of an appropriate integrator will make the PR review more effective. However, PR and integrator matching are now organized manually in Github. To reduce this cost, we presented an AIPM model to predict highly relevant integrator of incoming PRs. AIPM uses topic model to extract topics from the PRs, and builds a one-to-one correspondence between topics and integrators. Then, AIPM finds the most suitable integrator according to the maximum entry of the topic-document distribution. On average, AIPM can reach a precision of 60%, and even in some projects, can reach a precision of 80%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pull%20Request" title="pull Request">pull Request</a>, <a href="https://publications.waset.org/abstracts/search?q=integrator%20matching" title=" integrator matching"> integrator matching</a>, <a href="https://publications.waset.org/abstracts/search?q=Github" title=" Github"> Github</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20project" title=" open source project"> open source project</a>, <a href="https://publications.waset.org/abstracts/search?q=topic%20model" title=" topic model"> topic model</a> </p> <a href="https://publications.waset.org/abstracts/63126/aipman-integrator-and-pull-request-matching-model-in-github" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63126.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">299</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">794</span> Flow inside Micro-Channel Bounded by Superhydrophobic Surface with Eccentric Micro-Grooves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu%20Chen">Yu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiwei%20Ren"> Weiwei Ren</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaojing%20Mu"> Xiaojing Mu</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Zhang"> Feng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20Xu"> Yi Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The superhydrophobic surface is widely used to reduce friction for the flow inside micro-channel and can be used to control/manipulate fluid, cells and even proteins in lab-on-chip.
