intelligent driver model. 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">82</span> Application of 3-6 Years Old Children Basketball Appropriate Forms of Teaching Auxiliary Equipment in Early Childhood Basketball Game</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hai%20Zeng">Hai Zeng</a>, <a href="https://publications.waset.org/abstracts/search?q=Anqing%20Liu"> Anqing Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuguang%20Dan"> Shuguang Dan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Zhang"> Ying Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Li"> Yan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihang%20Zeng"> Zihang Zeng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Children are strong; the country strong, the development of children Basketball is a strategic advantage.

Network attack would be oppressed if attribution techniques are capable to trace back to the attackers after the hacking event. Therefore attributing these attacks to a particular identification becomes one of the important tasks when analysts attempt to differentiate and profile the attacker behind a piece of attack trace. To assist analysts in expose attackers behind the scenes, this paper researches on the connections between attribution traces and proposes probabilistic relevance based attribution patterns. This method facilitates the evaluation of the plausibility relevance between different traceable identifications. Furthermore, through analyzing the connections among traces, it could confirm the existence probability of a certain organization as well as discover its affinitive partners by the means of drawing relevance matrix from attribution traces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attribution%20trace" title="attribution trace">attribution trace</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20relevance" title=" probabilistic relevance"> probabilistic relevance</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20attack" title=" network attack"> network attack</a>, <a href="https://publications.waset.org/abstracts/search?q=attacker%20identification" title=" attacker identification"> attacker identification</a> </p> <a href="https://publications.waset.org/abstracts/61350/trace-network-a-probabilistic-relevant-pattern-recognition-approach-to-attribution-trace-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61350.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">366</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">77</span> Personalized Email Marketing Strategy: A Reinforcement Learning Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Zhang">Lei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tingting%20Xu"> Tingting Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20He"> Jun He</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhenyu%20Yan"> Zhenyu Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Email marketing is one of the most important segments of online marketing. It has been proved to be the most effective way to acquire and retain customers. The email content is vital to customers. Different customers may have different familiarity with a product, so a successful marketing strategy must personalize email content based on individual customers’ product affinity. In this study, we build our personalized email marketing strategy with three types of emails: nurture, promotion, and conversion. Each type of email has a different influence on customers. We investigate this difference by analyzing customers’ open rates, click rates and opt-out rates. Feature importance from response models is also analyzed. The goal of the marketing strategy is to improve the click rate on conversion-type emails. To build the personalized strategy, we formulate the problem as a reinforcement learning problem and adopt a Q-learning algorithm with variations. The simulation results show that our model-based strategy outperforms the current marketer’s strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=email%20marketing" title="email marketing">email marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=email%20content" title=" email content"> email content</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</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=Q-learning" title=" Q-learning"> Q-learning</a> </p> <a href="https://publications.waset.org/abstracts/152253/personalized-email-marketing-strategy-a-reinforcement-learning-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152253.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">194</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">76</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.

Fengqiao, a nearly 2000-year-old town was on the brink of dilapidation in the past few decades. The town faced such problems as poor construction quality, environmental degeneration, inadequate open space, cultural characteristics and industry vitality. Therefore, the research upholds the principle of ‘organic renewal’ and puts forward three practical updated strategies which are ‘Repair Old as Ever,' ‘Activate Function’ and ‘Fill in with The New’. Also as a participant in updating the design, the author aims to ‘keep the memory of the history and see the development of the present’ as the goal of updating the design and regards the process of town renewal as the experimental venue for realizing this purpose. The research will sum up innovations on the designing process and the engineering progress in the past two years, and find out the innovation experiment and the effect of its implementation on the methodological level of the organic renewal design in Fengqiao ancient town. From here, we can also enjoy the very characteristic development trend presented by China in the design practice of the organic renewal in the ancient town. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic%20town" title="characteristic town">characteristic town</a>, <a href="https://publications.waset.org/abstracts/search?q=Fengqiao" title=" Fengqiao"> Fengqiao</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20renewal" title=" organic renewal"> organic renewal</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20memory" title=" urban memory"> urban memory</a> </p> <a href="https://publications.waset.org/abstracts/84753/fengqiao-an-ongoing-experiment-with-urbanmemory-theory-in-an-ancient-town-and-itsdesign-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84753.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">159</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">73</span> Meditation Based Brain Painting Promotes Foreign Language Memory through Establishing a Brain-Computer Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhepeng%20Rui">Zhepeng Rui</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhenyu%20Gu"> Zhenyu Gu</a>, <a href="https://publications.waset.org/abstracts/search?q=Caitilin%20de%20B%C3%A9rigny"> Caitilin de Bérigny</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current study, we designed an interactive meditation and brain painting application to cultivate users’ creativity, promote meditation, reduce stress, and improve cognition while attempting to learn a foreign language. User tests and data analyses were conducted on 42 male and 42 female participants to better understand sex-associated psychological and aesthetic differences. Our method utilized brain-computer interfaces to import meditation and attention data to create artwork in meditation-based applications. Female participants showed statistically significantly different language learning outcomes following three meditation paradigms. The art style of brain painting helped females with language memory. Our results suggest that the most ideal methods for promoting memory attention were meditation methods and brain painting exercises contributing to language learning, memory concentration promotion, and foreign word memorization. We conclude that a short period of meditation practice can help in learning a foreign language.

This paper studies the recyclable nature of RLVs by presenting a solution method for determining minimum-fuel optimal trajectories using principles from optimal control theory and particle swarm optimization (PSO). This problem is formulated as a minimum-landing error powered descent problem where it is desired to move the RLV from a fixed set of initial conditions to three different sets of terminal conditions. However, unlike other powered descent studies, this paper considers the highly nonlinear effects caused by atmospheric drag, which are often ignored for studies on the Moon or on Mars. Rather than optimizing the controls directly, the throttle control is assumed to be bang-off-bang with a predetermined thrust direction for each phase of flight. The PSO method is verified in a one-dimensional comparison study, and it is then applied to the two-dimensional cases, the results of which are illustrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minimum-fuel%20optimal%20trajectory" title="minimum-fuel optimal trajectory">minimum-fuel optimal trajectory</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=reusable%20rocket" title=" reusable rocket"> reusable rocket</a>, <a href="https://publications.waset.org/abstracts/search?q=SpaceX" title=" SpaceX"> SpaceX</a> </p> <a href="https://publications.waset.org/abstracts/62012/minimum-fuel-optimal-trajectory-for-reusable-first-stage-rocket-landing-using-particle-swarm-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62012.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">277</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> Innovation of Teaching Methods in Vocational Education with Popularity Development Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hong%20Zeng">Hong Zeng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the process of popularization of higher education, it is necessary to innovate teaching methods in order to make the students cultivated suitable for the needs of social development.

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">69</span> Analytical Solutions for Tunnel Collapse Mechanisms in Circular Cross-Section Tunnels under Seepage and Seismic Forces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhenyu%20Yang">Zhenyu Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiunan%20Chen"> Qiunan Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaocheng%20Huang"> Xiaocheng Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reliable prediction of tunnel collapse remains a prominent challenge in the field of civil engineering. In this study, leveraging the nonlinear Hoek-Brown failure criterion and the upper-bound theorem, an analytical solution for the collapse surface of shallowly buried circular tunnels was derived, taking into account the coupled effects of surface loads and pore water pressures. Initially, surface loads and pore water pressures were introduced as external force factors, equating the energy dissipation rate to the external force, yielding our objective function. Subsequently, the variational method was employed for optimization, and the outcomes were juxtaposed with previous research findings. Furthermore, we utilized the deduced equation set to systematically analyze the influence of various rock mass parameters on collapse shape and extent. To validate our analytical solutions, a comparison with prior studies was executed. The corroboration underscored the efficacy of our proposed methodology, offering invaluable insights for collapse risk assessment in practical engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tunnel%20roof%20stability" title="tunnel roof stability">tunnel roof stability</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title=" analytical solution"> analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=hoek%E2%80%93brown%20failure%20criterion" title=" hoek–brown failure criterion"> hoek–brown failure criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=limit%20analysis" title=" limit analysis"> limit analysis</a> </p> <a href="https://publications.waset.org/abstracts/174775/analytical-solutions-for-tunnel-collapse-mechanisms-in-circular-cross-section-tunnels-under-seepage-and-seismic-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174775.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">84</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> 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">67</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.

In the high-rise buildings, the core-tube layout is closely associated with user’s physical activities which will affect human’s health in a long-term. As for the white-collars who spends the amount of time working in the office tower, using staircase seems to provide an opportunity for them to increase the physical activities in the workplaces. This paper is aiming to find out the specific relationship between health and core-tube in the office tower through analyzing the correlation between staircase’s layout and user’s health. The variables of staircase’s layout are consisted of two indicators: plan layout and space design, including nine factors while health variable is applying BIM as the only main factor. 14 office towers in downtown Shanghai are selected as the research samples because of its typical users’ pattern and similar core-tube layout. In the result, it is obvious that the users from these 14 cases have higher BMI than average partly because that the staircases are mainly designed for emergency and fire instead of daily use. After the regression and correlation analysis of the variables of health and staircases, it’s found that users’ BMI is significantly associated with the factors of floor guide-signs and distance from lobby to the staircase. In addition, the factors of comfort level of staircase such as width and daylighting have a certain correlation with users’ BMI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=office%20tower" title="office tower">office tower</a>, <a href="https://publications.waset.org/abstracts/search?q=staircase" title=" staircase"> staircase</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a> </p> <a href="https://publications.waset.org/abstracts/72756/research-on-users-obesity-and-office-tower-core-tube-design-from-the-perspective-of-physical-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72756.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">226</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 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.

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">8</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">59</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. An alkali fusion process was utilized to separate silicate supernatant and the sediment effectively. 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">57</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">56</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 study, oxide coatings were produced on ZA27 zinc-aluminum alloy by a plasma electrolytic oxidation (PEO) method. Three coatings were deposited by using three various electrolytes, i.e. silicate, aluminate and aluminate/borate composite solutions. The current density is set at 0.1A/cm2, deposition time is 40 mins for all the deposition processes. The surface morphology and phase structure of the three coatings were characterized by scanning electron microscopy （SEM） and X-ray diffraction (XRD). Pin-on-disc sliding wear tests were conducted to test the tribological properties of coatings.

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. Thus, this facile laser irradiation approach might provide a way for the fabrication of porous microspheres without phase-transition. <p class="card-text"><strong>Keywords:</strong> <a
