It is an effective way to enhance the performance of data mining for KGs with scarce resources. In real-world applications, the neighborhood structures of the same entities in different KGs tend to be non-isomorphic, which makes the representation of entities contain diverse semantic information and then poses a great challenge for CLEA. In this paper, we try to address this challenge from two perspectives. On the one hand, the cross-KG relation completion rules are designed with the alignment constraint of entities and relations to improve the topology isomorphism of two KGs. On the other hand, a representation method combining isomorphic weights is designed to include more isomorphic semantics for counterpart entities, which will benefit the CLEA. Experiments show that our model can improve the isomorphism of two KGs and the alignment performance, especially for two non-isomorphic KGs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20graphs" title="knowledge graphs">knowledge graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-lingual%20entity%20alignment" title=" cross-lingual entity alignment"> cross-lingual entity alignment</a>, <a href="https://publications.waset.org/abstracts/search?q=non-isomorphic" title=" non-isomorphic"> non-isomorphic</a>, <a href="https://publications.waset.org/abstracts/search?q=relation%20completion" title=" relation completion"> relation completion</a> </p> <a href="https://publications.waset.org/abstracts/155961/cross-knowledge-graph-relation-completion-for-non-isomorphic-cross-lingual-entity-alignment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155961.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">123</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">72</span> Analysis of Patent Protection of Bone Tissue Engineering Scaffold Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yunwei%20Zhang">Yunwei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Na%20Li"> Na Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuhong%20Niu"> Yuhong Niu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bone tissue engineering scaffold was regarded as an important clinical technology of curing bony defect. The patent protection of bone tissue engineering scaffold had been paid more attention and strengthened all over the world. This study analyzed the future development trends of international technologies in the field of bone tissue engineering scaffold and its patent protection. This study used the methods of data classification and classification indexing to analyze 2718 patents retrieved in the patent database. Results showed that the patents coming from United States had a competitive advantage over other countiries in the field of bone tissue engineering scaffold. The number of patent applications by a single company in U.S. was a quarter of that of the world. However, the capability of R&D in China was obviously weaker than global level, patents mainly coming from universities and scientific research institutions. Moreover, it would be predicted that synthetic organic materials as new materials would be gradually replaced by composite materials. The patent technology protections of composite materials would be more strengthened in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20engineering" title="bone tissue engineering">bone tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20analysis" title=" patent analysis"> patent analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Scaffold%20material" title=" Scaffold material"> Scaffold material</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20protection" title=" patent protection"> patent protection</a> </p> <a href="https://publications.waset.org/abstracts/105186/analysis-of-patent-protection-of-bone-tissue-engineering-scaffold-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105186.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">133</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">71</span> Adalimumab Therapy for Inflammatory Discitis Associated with Spondyloarthropathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liu%20Yuhong">Liu Yuhong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussen%20Mansai"> Hussen Mansai</a>, <a href="https://publications.waset.org/abstracts/search?q=Mei%20Chunli"> Mei Chunli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inflammatory discitis is a sterile inflammatary disease that typically presents with abnormalities in two adjacent vertebral bodies and the intervening disk. Diagnosis this disorder is usually difficult and ideal management remains controversial. In this report，we examine a case of inflammatory discitis in a 56 year old female in which treatment with adalimumab ameliorated symptoms. The 56-year-old female patient developed repeatedly inflammatory discitis in the past three years, presenting with severe back pain, an elevated C-reactive protein and erythrocyte sedimentation rate, radiological erosive changes in vertebral and intervertebral disk of the spine. Surgical treatment, antibiotics and non steroidal anti-inflammatory drugs(NSAIDs) were used, but the patient still suffered from recurrent onset of unbearable backache. Three years later from the patient’s first admission，adalimumab was prescribed due to the third occurrence of Anderson lesions, which she had been suffering from for years. Soon after the same day of adalimumab therapy, her symptoms had a dramatic improvement. On the following day she could stand and walk slowly, her CRP and ESR were decreased to nearly normal levels in 4 weeks. Human leukocyte antigen (HLA)-typing analysis revealed a positive result for HLA-B27, the patient’s inflammatory discitis was considered to be associated with spondyloarthropathy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adalimumab" title="adalimumab">adalimumab</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20discitis" title=" inflammatory discitis"> inflammatory discitis</a>, <a href="https://publications.waset.org/abstracts/search?q=spondyloarthropathy" title=" spondyloarthropathy"> spondyloarthropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=patient" title=" patient "> patient </a> </p> <a href="https://publications.waset.org/abstracts/30043/adalimumab-therapy-for-inflammatory-discitis-associated-with-spondyloarthropathy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30043.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">254</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">70</span> Comparative Analysis of Patent Protection between Health System and Enterprises in Shanghai, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Na%20Li">Na Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yunwei%20Zhang"> Yunwei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuhong%20Niu"> Yuhong Niu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study discussed the patent protections of health system and enterprises in Shanghai. The comparisons of technical distribution and scopes of patent protections between Shanghai health system and enterprises were used by the methods of IPC classification, co-words analysis and visual social network. Results reflected a decreasing order within IPC A61 area, namely A61B, A61K, A61M, and A61F. A61B required to be further investigated. The highest authorized patents A61B17 of A61B of IPC A61 area was found. Within A61B17, fracture fixation, ligament reconstruction, cardiac surgery, and biopsy detection were regarded as common concerned fields by Shanghai health system and enterprises. However, compared with cardiac closure which Shanghai enterprises paid attention to, Shanghai health system was more inclined to blockages and hemostatic tools. The results also revealed that the scopes of patent protections of Shanghai enterprises were relatively centralized. Shanghai enterprises had a series of comprehensive strategies for protecting core patents. In contrast, Shanghai health system was considered to be lack of strategic patent protections for core patents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=co-words%20analysis" title="co-words analysis">co-words analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=IPC%20classification" title=" IPC classification"> IPC classification</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20protection" title=" patent protection"> patent protection</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20distribution" title=" technical distribution"> technical distribution</a> </p> <a href="https://publications.waset.org/abstracts/105197/comparative-analysis-of-patent-protection-between-health-system-and-enterprises-in-shanghai-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105197.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">134</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">69</span> Analysis and Suggestion on Patent Protection in Shanghai, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuhong%20Niu">Yuhong Niu</a>, <a href="https://publications.waset.org/abstracts/search?q=Na%20Li"> Na Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunlin%20Jin"> Chunlin Jin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansheng%20Ding"> Hansheng Ding</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study reviewed all types of patents applied by Shanghai health system to analyze how patent development in China from the year of 1990 to 2012. The study used quantitative and comparative analysis to investigate the change and trends of patent numbers, patent types, patent claims, forward citations, patent life, patent transactions, etc. Results reflected an obviously increased numbers of invention patents, applications, and authorizations and short-life patents, but the ratio of invention patents represented an up and down change. Forward citations and transactions ratio always kept at a low level. The results meant that the protection of intellectual property in the Shanghai health sector had made great progress and lots of positive changes due to incentive policies by local government. However, the low-quality patents, at the same time, increased rapidly. Thus, in the future, it is suggested that the quality management should be strengthened, and invents should be estimated before patent application. It is also suggested that the incentives for intellectual property should be optimized to promote the comprehensive improvement of patent quantity and quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patent%20claims" title="patent claims">patent claims</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20citations" title=" forward citations"> forward citations</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20life" title=" patent life"> patent life</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20transactions%20ratio" title=" patent transactions ratio"> patent transactions ratio</a> </p> <a href="https://publications.waset.org/abstracts/88974/analysis-and-suggestion-on-patent-protection-in-shanghai-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88974.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">161</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">68</span> Na Promoted Ni/γ-Al2O3 Catalysts Prepared by Solution Combustion Method for Syngas Methanation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yan%20Zeng">Yan Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongfang%20Ma"> Hongfang Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Haitao%20Zhang"> Haitao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiyong%20Ying"> Weiyong Ying</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ni-based catalysts with different amounts of Na as promoter from 2 to 6 wt % were prepared by solution combustion method.

Adding 2 wt% Na remarkably improves catalytic activity and long-term stability, attributed to its smaller mean NiO particle size, better distribution, and milder metal-support interaction. However, excess addition of Na results in deactivation distinctly due to the blockage of active sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nickel%20catalysts" title="nickel catalysts">nickel catalysts</a>, <a href="https://publications.waset.org/abstracts/search?q=syngas%20methanation" title=" syngas methanation"> syngas methanation</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium" title=" sodium"> sodium</a>, <a href="https://publications.waset.org/abstracts/search?q=solution%20combustion%20method" title=" solution combustion method "> solution combustion method </a> </p> <a href="https://publications.waset.org/abstracts/9499/na-promoted-nigh-al2o3-catalysts-prepared-by-solution-combustion-method-for-syngas-methanation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9499.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">407</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">67</span> Case-Based Reasoning Approach for Process Planning of Internal Thread Cold Extrusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Zhang">D.

Security risks arising from international conflicts seem inescapable. Some countries have begun to build their capacity to deal with the globalization of security risks. They establish disembedding security mechanisms that transcend spatial or temporal boundaries and promote security cooperation with countries or regions that are not geographically close. This paper proposes four hypotheses of the phenomenon of "risks and security disembedding" in the post-Cold War international society and uses them to explain The United Kingdom’s behavior in the Bosnian War and the Russo-Ukrainian War. In the Bosnian War, confident in its own security and focused on maintaining European stability, The UK has therefore chosen to be cautious in its use of force in international frameworks such as the EU and to maintain a very limited intervention in Bosnia and Herzegovina's affairs. In contrast, the failure of the EU and NATO’s security mechanism in the Russo-Ukrainian war heightened Britain's anxiety, and the volatile international situation led it to show a strong tendency towards security disembedding, choosing to conclude security communities with extra-territorial states. Analysis suggests that security mechanisms are also the starting point of conflict and that countries will rely more on disembedding mechanisms to counteract the global security risks. The current mechanism of security disembedding occurs as a result of the global proliferation of security perceptions as a symbolic token and the recognition of an expert system of security mechanisms formed by states with similar security perceptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disembedding%20mechanism" title="disembedding mechanism">disembedding mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=bosnia%20war" title=" bosnia war"> bosnia war</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20russian-ukrainian%20war" title=" the russian-ukrainian war"> the russian-ukrainian war</a>, <a href="https://publications.waset.org/abstracts/search?q=british%20security%20strategy" title=" british security strategy"> british security strategy</a> </p> <a href="https://publications.waset.org/abstracts/167052/a-study-of-the-british-security-disembedding-mechanism-from-a-comparative-political-perspective-centering-on-the-bosnia-war-and-the-russian-ukrainian-war" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167052.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">86</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">64</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">63</span> Challenges of Cryogenic Fluid Metering by Coriolis Flowmeter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evgeniia%20Shavrina">Evgeniia Shavrina</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Zeng"> Yan Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Boo%20Cheong%20Khoo"> Boo Cheong Khoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinh-Tan%20Nguyen"> Vinh-Tan Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper is aimed at providing a review of error sources in cryogenic metering by Coriolis flowmeters (CFMs). Whereas these flowmeters allow accurate water metering, high uncertainty and low repeatability are commonly observed at cryogenic fluid metering, which is often necessary for effective renewable energy production and storage. The sources of these issues might be classified as general and cryogenic specific challenges. A conducted analysis of experimental and theoretical studies shows that material behaviour at cryogenic temperatures, composition variety, and multiphase presence are the most significant cryogenic challenges. At the same time, pipeline diameter limitation, ambient vibration impact, and drawbacks of the installation may be highlighted as the most important general challenges of cryogenic metering by CFM. Finally, the techniques, which mitigate the impact of these challenges are reviewed, and future development direction is indicated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Coriolis%20flowmeter" title="Coriolis flowmeter">Coriolis flowmeter</a>, <a href="https://publications.waset.org/abstracts/search?q=cryogenic" title=" cryogenic"> cryogenic</a>, <a href="https://publications.waset.org/abstracts/search?q=multicomponent%20flow" title=" multicomponent flow"> multicomponent flow</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a> </p> <a href="https://publications.waset.org/abstracts/134098/challenges-of-cryogenic-fluid-metering-by-coriolis-flowmeter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134098.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">152</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">62</span> The Twin Terminal of Pedestrian Trajectory Based on City Intelligent Model (CIM) 4.0</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Xi">Chen Xi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lao%20Xuerui"> Lao Xuerui</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Junjie"> Li Junjie</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiang%20Yike"> Jiang Yike</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Hanwei"> Wang Hanwei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeng%20Zihao"> Zeng Zihao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To further promote the development of smart cities, the microscopic "nerve endings" of the City Intelligent Model (CIM) are extended to be more sensitive.

There are legal reasons for this, namely the lack of protection for domestic pets in mainland China, where only wildlife protection laws exist. At a social level, the ease with which families adopt pets and the lack of a social view of animal nature has led to the frequent abandonment and loss of stray animals. If left unmanaged, conflicts between humans and stray animals can also increase.

However, when it comes to very large metropolitan areas, microscopic traffic simulation requires more resources and become time-consuming, then macroscopic traffic simulation aggregate trends of interests rather than individual vehicle traces. In this paper, we describe the architecture and implementation of the actor system of microscopic traffic simulation, which exploits the distributed architecture of modern-day cloud computing. The results demonstrate that our architecture achieves high-performance and outperforms all the other traditional microscopic software in all tasks. To the best of our knowledge, this the first system that enables single-agent behavior in macroscopic traffic simulation. We thus believe it contributes to a new type of system for traffic simulation, which could provide individual vehicle behaviors in microscopic traffic simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=actor%20system" title="actor system">actor system</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20system" title=" distributed system"> distributed system</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20simulation" title=" traffic simulation"> traffic simulation</a> </p> <a href="https://publications.waset.org/abstracts/128664/distributed-actor-system-for-traffic-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128664.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">192</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">57</span> The Urban Stray Animal Identification Management System Based on YOLOv5</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Xi">Chen Xi</a>, <a href="https://publications.waset.org/abstracts/search?q=LIU%20Xuebin"> LIU Xuebin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuan%20Sinman"> Kuan Sinman</a>, <a href="https://publications.waset.org/abstracts/search?q=LI%20Haofeng"> LI Haofeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Huang%20Hongming"> Huang Hongming</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeng%20Chengyu"> Zeng Chengyu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lao%20Xuerui"> Lao Xuerui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stray animals are on the rise in mainland China's cities. There are legal reasons for this, namely the lack of protection for domestic pets in mainland China, where only wildlife protection laws exist. At a social level, the ease with which families adopt pets and the lack of a social view of animal nature have led to the frequent abandonment and loss of stray animals. If left unmanaged, conflicts between humans and stray animals can also increase. This project provides an inexpensive and widely applicable management tool for urban management by collecting videos and pictures of stray animals captured by surveillance or transmitted by humans and using artificial intelligence technology (mainly using Yolov5 recognition technology) and recording and managing them in a database. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20planning" title="urban planning">urban planning</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20governance" title=" urban governance"> urban governance</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20network" title=" convolutional neural network"> convolutional neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20vision" title=" machine vision"> machine vision</a> </p> <a href="https://publications.waset.org/abstracts/168301/the-urban-stray-animal-identification-management-system-based-on-yolov5" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168301.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">99</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">56</span> Research on Transmission Parameters Determination Method Based on Dynamic Characteristic Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baoshan%20Huang">Baoshan Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Fanbiao%20Bao"> Fanbiao Bao</a>, <a href="https://publications.waset.org/abstracts/search?q=Bing%20Li"> Bing Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Lianghua%20Zeng"> Lianghua Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20Zheng"> Yi Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parameter control strategy based on statistical characteristics can analyze the choice of the transmission ratio of an automobile transmission.

This study examined FLTA by administering questionnaires to 235 in-service teachers to investigate the impacts of educational stages and teaching experience on FLTA. The statistical results show that secondary school teachers exhibit significantly higher levels of FLTA than their primary counterparts, especially in “lack of student interest” and “fear of negative evaluation”. Novice teachers are significantly more anxious than experienced teachers in the dimension of ‘teaching inexperience’, while no other differences are shown in other aspects. No interaction effects are found between the two variables. Pedagogical implications for understanding FLTA in different educational and experiential stages and corresponding anxiety-reducing strategies are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20language%20teaching%20anxiety" title="foreign language teaching anxiety">foreign language teaching anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=in-service%20teachers" title=" in-service teachers"> in-service teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=novice%20and%20experienced%20teachers" title=" novice and experienced teachers"> novice and experienced teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20and%20secondary%20school" title=" primary and secondary school"> primary and secondary school</a> </p> <a href="https://publications.waset.org/abstracts/194111/foreign-language-teaching-anxiety-among-in-service-english-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194111.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">7</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">54</span> Adsorption of Acetone Vapors by SBA-16 and MCM-48 Synthesized from Rice Husk Ash</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wanting%20Zeng">Wanting Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsunling%20Bai"> Hsunling Bai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Silica was extracted from agriculture waste rice husk ash (RHA) and was used as the silica source for synthesis of RMCM-48 and RSBA-16.

The CTAB/Si and F127/Si molar ratio was employed to control the structure properties of the obtained RMCM-48 and RSBA-16 materials. The N2 adsorption-desorption results showed the micro-mesoporous RSBA-16 possessed high specific surface areas (662-1001 m2/g). All the obtained RSBA-16 materials were applied as the adsorbents for acetone adsorption. And the breakthrough tests clearly revealed that the RSBA-16(0.004) materials could achieve the highest acetone adsorption capacity of 186 mg/g under 1000 ppmv acetone vapor concentration at 25oC, which was also superior to ZSM-5 (71mg/g) and MCM-41 (157mg/g) under same test conditions.

Focusing on analyzing the similarities and differences in origin, evolution, public dispute, policy dynamics between China and the United States, the article depicts a panorama and explores possible causes. Both China and the United States continue to learn from historical legacy and invent new programs to perfect school choice policy but the outcomes are so different. On the one hand, the percentage of public schools in China remains high all along, while there is a considerably significant reduction in the United States. On the other hand, there is more governmental intervention in the United States with continuous and constant policy updates and adjustment. Finally, this article adopts public-private partnerships (PPP) to seek to provide insights into differences between the two countries and argue that school choice is not only the production of education marketization and corporation but also driven by political mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China" title="China">China</a>, <a href="https://publications.waset.org/abstracts/search?q=United%20States" title=" United States"> United States</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20choice" title=" school choice"> school choice</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20analysis" title=" comparative analysis"> comparative analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=policy" title=" policy"> policy</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20private%20partnerships" title=" public private partnerships"> public private partnerships</a> </p> <a href="https://publications.waset.org/abstracts/137632/a-comparative-study-of-school-choice-china-and-the-united-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137632.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">189</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">52</span> Highly Sensitive Fiber-Optic Curvature Sensor Based on Four Mode Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qihang%20Zeng">Qihang Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Xu"> Wei Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Shen"> Ying Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Changyuan%20Yu"> Changyuan Yu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a highly sensitive fiber-optic curvature sensor based on four mode fiber (FMF) is presented and investigated. The proposed sensing structure is constructed by fusing a section of FMF into two standard single mode fibers (SMFs) concatenated with two no core fiber (NCF), i.e., SMF-NCF-FMF-NCF-SMF structure is fabricated. The length of the NCF is very short about 1 millimeter acting as exciting/recoupling the light from/into the core of the SMF, while the FMF is with 3 centimeters long supporting four eigenmodes including LP₀₁, LP₁₁, LP₂₁ and LP₀₂. High core modes in FMF can be effectively stimulated owing to mismatched mode field distribution and the mainly sensing principle is based on modal interferometer spectrum analysis. Different curvatures induce different strains on the FMF such that affecting the modal excitation, resulting spectrum shifts. One can get the curvature value by tracking the wavelength shifting. Experiments have been done to address the sensing performance, which is about 7.8 nm/m⁻¹ within a range of 1.90 m⁻¹~3.18 m⁻¹. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curvature" title="curvature">curvature</a>, <a href="https://publications.waset.org/abstracts/search?q=four%20mode%20fiber" title=" four mode fiber"> four mode fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=highly%20sensitive" title=" highly sensitive"> highly sensitive</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20interferometer" title=" modal interferometer"> modal interferometer</a> </p> <a href="https://publications.waset.org/abstracts/99798/highly-sensitive-fiber-optic-curvature-sensor-based-on-four-mode-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99798.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">191</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">51</span> Incorporating Information Gain in Regular Expressions Based Classifiers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosa%20L.%20Figueroa">Rosa L.

In this work, an approach for fabricating porous spheres of nanoparticles was presented, in which the nanoparticles were welded together to form micro spheres by simply irradiating the nanoparticles in liquid medium by a picosecond laser. As an example, anatase titanium dioxide was chosen as a typical material on account of its metastability. The structure and morphologies of the products were characterised by X-ray diffraction (XRD), scanning electron microscope (SEM), Raman, and high-resolution transmission electron microscopy (HRTEM), respectively. The results showed that, anatase titanium dioxide micro spheres (2-10 μm) with macroporous (10-100 nm) were prepared from nano-anatase titanium dioxide nanoparticles (10-100 nm). The formation process of polycrystalline anatase titanium dioxide microspheres was investigated with different liquid mediums and the input laser fluences.

An analytical expression of vertical stiffness of the nonlinear isolator is derived and numerical simulation on the effect of the geometric design parameters is carried out. Besides, a pre-compressed QZS shock isolation system model is established. The stiffness characteristic of the system is studied and the effects of excitation amplitude and friction damping on shock isolation performance are discussed respectively. The research results show that in comparison with linear shock isolation system, the pre-compressed QZS shock isolation system could realize constant-force or approximately constant-force function and perform better anti-impact performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quasi-zero-stiffness" title="quasi-zero-stiffness">quasi-zero-stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=constant-force" title=" constant-force"> constant-force</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-compressed" title=" pre-compressed"> pre-compressed</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20deformation" title=" large deformation"> large deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20isolation" title=" shock isolation"> shock isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20damping" title=" friction damping"> friction damping</a> </p> <a href="https://publications.waset.org/abstracts/39796/shock-isolation-performance-of-a-pre-compressed-large-deformation-shock-isolator-with-quasi-zero-stiffness-characteristic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39796.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">697</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">47</span> Dimensionality and Superconducting Parameters of YBa2Cu3O7 Foams </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Koblischka">Michael Koblischka</a>, <a href="https://publications.waset.org/abstracts/search?q=Anjela%20%20Koblischka-Veneva"> Anjela Koblischka-Veneva</a>, <a href="https://publications.waset.org/abstracts/search?q=XianLin%20%20Zeng"> XianLin Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Essia%20%20Hannachi"> Essia Hannachi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yassine%20%20Slimani"> Yassine Slimani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Superconducting foams of YBa2Cu3O7 (abbreviated Y-123) were produced using the infiltration growth (IG) technique from Y2BaCuO5 (Y-211) foams. The samples were investigated by SEM (scanning electron microscopy) and electrical resistivity measurements. SEM observations indicated the specific microstructure of the foam struts with numerous tiny Y-211 particles (50-100 nm diameter) embedded in channel-like structures between the Y-123 grains. The investigation of the excess conductivity of different prepared composites was analyzed using Aslamazov-Larkin (AL) model. The investigated samples comprised of five distinct fluctuation regimes, namely short-wave (SWF), one-dimensional (1D), two-dimensional (2D), three-dimensional (3D), and critical (CR) fluctuations regimes. The coherence length along the c-axis at zero-temperature (ξc(0)), lower and upper critical magnetic fields (Bc1 and Bc2), critical current density (Jc) and numerous other superconducting parameters were estimated from the data. The analysis reveals that the presence of the tiny Y-211 particles alters the excess conductivity and the fluctuation behavior observed in standard YBCO samples. <p
