Diarrhea syndrome is common in weaning piglets and often treated with antibiotics as a feed additive, leading to the rapid spread of antibiotic resistance and posing high health risks to humans. The study aimed to alleviate diarrhea syndrome with traditional herbal medicine, Xiang Sha Liu Jun Zi Tang, whose effects enhanced digestive function. Piglets at 4 weeks old with stool classified to Bristol stool classification type 6 or type 7 were randomly divided into the control group, group A (1% of Xiang Sha Liu Jun Zi Tang) and group B (0.1% Colistin). The piglets were administrated for 7 days, and their weight, feed intake, and stool score were recorded daily before and after the trial. The results showed that the diarrhea index score in group A and group B improved significantly compared to the control group, indicating that Xiang Sha Liu Jun Zi Tang may have the same effect on alleviating diarrhea syndrome as Colistin, and it may be another replacement for antibiotics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pig" title="pig">pig</a>, <a href="https://publications.waset.org/abstracts/search?q=diarrhea" title=" diarrhea"> diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=herbal%20medicine" title=" herbal medicine"> herbal medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiang%20Sha%20Liu%20Jun%20Zi%20Tang" title=" Xiang Sha Liu Jun Zi Tang"> Xiang Sha Liu Jun Zi Tang</a> </p> <a href="https://publications.waset.org/abstracts/182911/the-effects-of-xiang-sha-liu-jun-zi-tang-to-diarrhea-and-growth-performance-of-piglets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182911.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">51</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">93</span> The Meaningful Pixel and Texture: Exploring Digital Vision and Art Practice Based on Chinese Cosmotechnics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xingdu%20Wang">Xingdu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Charlie%20Gere"> Charlie Gere</a>, <a href="https://publications.waset.org/abstracts/search?q=Emma%20Rose"> Emma Rose</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuxuan%20Zhao"> Yuxuan Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study introduces a fresh perspective on the digital realm through an examination of the Chinese concept of Xiang, elucidating how it can build an understanding of pixels and textures on screens as digital trigrams. This concept attempts to offer an outlook on the intersection of digital technology and the natural world, thereby contributing to discussions about the harmonious relationship between humans and technology. The study looks for the ancient Chinese theory of Xiang as a key to establishing the theories and practices to respond to the problem of Contemporary Chinese technics. Xiang is a Chinese method of understanding the essentials of things through appearances, which differs from the method of science in the Westen. Xiang, the basement of Chinese visual art, is rooted in ancient Chinese philosophy and connected to the eight trigrams. The discussion of Xiang connects art, philosophy, and technology. This paper connects the meaning of Xiang with the 'truth appearing' philosophically through the analysis of the concepts of phenomenon and noumenon and the unique Chinese way of observing. Hereafter, the historical interconnection between ancient painting and writing in China emphasizes their relationship between technical craftsmanship and artistic expression. In digital, the paper blurs the traditional boundaries between images and text on digital screens in theory. Lastly, this study identified an ensemble concept relating to pixels and textures in computer vision, drawing inspiration from AI image recognition in Chinese paintings. In art practice, by presenting a fluid visual experience in the form of pixels, which mimics the flow of lines in traditional calligraphy and painting, it is hoped that the viewer will be brought back to the process of the truth appearing as defined by the 'Xiang’. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chinese%20cosmotechnics" title="Chinese cosmotechnics">Chinese cosmotechnics</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=contemporary%20Neo-Confucianism" title=" contemporary Neo-Confucianism"> contemporary Neo-Confucianism</a>, <a href="https://publications.waset.org/abstracts/search?q=texture%20and%20pixel" title=" texture and pixel"> texture and pixel</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiang" title=" Xiang"> Xiang</a> </p> <a href="https://publications.waset.org/abstracts/174685/the-meaningful-pixel-and-texture-exploring-digital-vision-and-art-practice-based-on-chinese-cosmotechnics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174685.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">64</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">92</span> Heroes in Hollywood Cinema: An Examination of 'Da Yin Xi Sheng, Da Xiang Wu Xing' Concepts in Daoism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun%20Cui">Jun Cui</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Qin"> Mark Qin</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Chang"> Wei Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Celtic%20Wang"> Celtic Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In popular culture, there are Western heroes and Eastern heroes. The differentiation between them is not identified on color, ethnicity, physique, or appearance, nor does it pertain to the pejorative discourses of ‘Western hegemonic culture’ and ‘Orientalism.’ Regardless of nations, heroes frequently exemplify Daoist concepts such as ‘powerful sound is silent, powerful form is formless’. In this paper, the author argues that the characters in the Hollywood film Avatar: The Way of Water embody the archetype of a Xia, carrying out the duties and behaviors typical of this archetype, which aligns with the 'Da Yin Xi Sheng, Da Xiang Wu Xing' concepts of Daoism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daoism" title="Daoism">Daoism</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20culture" title=" Chinese culture"> Chinese culture</a>, <a href="https://publications.waset.org/abstracts/search?q=heroism" title=" heroism"> heroism</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhuangzi" title=" Zhuangzi"> Zhuangzi</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20study" title=" film study"> film study</a> </p> <a href="https://publications.waset.org/abstracts/194595/heroes-in-hollywood-cinema-an-examination-of-da-yin-xi-sheng-da-xiang-wu-xing-concepts-in-daoism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194595.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">11</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">91</span> Image Reconstruction Method Based on L0 Norm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianhong%20Xiang">Jianhong Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao%20Xiang"> Hao Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Linyu%20Wang"> Linyu Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compressed sensing (CS) has a wide range of applications in sparse signal reconstruction. Aiming at the problems of low recovery accuracy and long reconstruction time of existing reconstruction algorithms in medical imaging, this paper proposes a corrected smoothing L0 algorithm based on compressed sensing (CSL0). First, an approximate hyperbolic tangent function (AHTF) that is more similar to the L0 norm is proposed to approximate the L0 norm. Secondly, in view of the "sawtooth phenomenon" in the steepest descent method and the problem of sensitivity to the initial value selection in the modified Newton method, the use of the steepest descent method and the modified Newton method are jointly optimized to improve the reconstruction accuracy. Finally, the CSL0 algorithm is simulated on various images. The results show that the algorithm proposed in this paper improves the reconstruction accuracy of the test image by 0-0. 98dB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smoothed%20L0" title="smoothed L0">smoothed L0</a>, <a href="https://publications.waset.org/abstracts/search?q=compressed%20sensing" title=" compressed sensing"> compressed sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=sparse%20reconstruction" title=" sparse reconstruction"> sparse reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/155598/image-reconstruction-method-based-on-l0-norm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155598.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">116</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">90</span> Idiocenntrism to innovative action, multi-level perspective on moderating effects of emotional self-regulation, trust and CSR</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shuhong%20Wang">Shuhong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiang%20Yi"> Xiang Yi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Through a survey of approximately 340 employees from four Chinese companies and employing cross-level analysis, this study reveals that certain cultural syndromes may exert both direct and indirect influences on such behaviors.

The acoustic emission signals are analyzed based on both parameter and wave information, which is also compared with the beam deflection measured by displacement sensors. The results indicate that using acoustic emission technology can detect damage initiation and development effectively, especially in the early stage of the damage development, which can not be detected by the common monitoring technology. Furthermore, the positioning of the damage based on the acoustic emission signals can be proved to be reasonable. This job can be an important attempt for the future long-time monitoring of the real concrete structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20emission%20technology" title="acoustic emission technology">acoustic emission technology</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20beam" title=" concrete beam"> concrete beam</a>, <a href="https://publications.waset.org/abstracts/search?q=parameter%20analysis" title=" parameter analysis"> parameter analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20analysis" title=" wave analysis"> wave analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=positioning" title=" positioning"> positioning</a> </p> <a href="https://publications.waset.org/abstracts/108497/test-research-on-damage-initiation-and-development-of-a-concrete-beam-using-acoustic-emission-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108497.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">141</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">85</span> Three Dimensional Numerical Analysis for Longitudinal Seismic Response of Tunnels under Asynchronous Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peng%20Li">Peng Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Er-xiang%20Song"> Er-xiang Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical analysis of longitudinal tunnel seismic response due to spatial variation of earthquake ground motion is an important issue that cannot be ignored in the design and safety evaluation of tunnel structures.

With the reaction material of sclareol is provided as plant extract, many sorts of complex impurities exist in the mother liquor. Due to the difficulty in recycling sclareolide after solvent recovery, it is common practice for the factories to discard the mother liquor, which not only results in loss of sclareolide, but also contributes extra environmental burden. In this paper, a process based on adsorption and elution has been presented for recycling of sclareolide from mother liquor. After pretreatment of the crystallization mother liquor by HZ-845 resin to remove parts of impurities, sclareolide is adsorbed by HZ-816 resin. The HZ-816 resin loaded with sclareolide is then eluted by elution solvent. Finally, the eluent containing sclareolide is concentrated and fed into the crystallization step in the process. By adoption of the recycle from mother liquor, total yield of sclareolide increases from 86% to 90% with a stable purity of the final sclareolide products maintained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sclareolide" title="sclareolide">sclareolide</a>, <a href="https://publications.waset.org/abstracts/search?q=resin" title=" resin"> resin</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=chromatography" title=" chromatography"> chromatography</a> </p> <a href="https://publications.waset.org/abstracts/44832/recycling-of-sclareolide-in-the-crystallization-mother-liquid-of-sclareolide-by-adsorption-and-chromatography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44832.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">238</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">80</span> Construction of a Low Carbon Eco-City Index System Based on CAS Theory: A Case of Hexi Newtown in Nanjing, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xu%20Tao">Xu Tao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yilun%20Xu"> Yilun Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dingwei%20Xiang"> Dingwei Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaofei%20Sun"> Yaofei Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The practice of urban planning and construction based on the concept of the “low carbon eco-city” has been universally accepted by the academic community in response to urban issues such as population, resources, environment, and social development.

As residents' daily commuting necessities, cars cause a lot of exhaust emissions and urban traffic congestion. In the "Fourteenth Five Year Plan" of China, it is proposed to strive to reach the peak of carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060. Urban transport accounts for a high proportion of carbon emission sources. It is an important driving force for the realization of China's carbon peak strategy. Some cities have introduced and implemented the policy of "car restriction" to solve related urban problems by reducing the use of cars. This paper analyzes the implementation of the "automobile restriction" policy, evaluates the relevant effects of the automobile restriction policy, and discusses how to better optimize the "automobile restriction" policy in the process of urban governance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20emission" title="carbon emission">carbon emission</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20jams" title=" traffic jams"> traffic jams</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20restrictions" title=" vehicle restrictions"> vehicle restrictions</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluate" title=" evaluate"> evaluate</a> </p> <a href="https://publications.waset.org/abstracts/159386/research-on-the-public-policy-of-vehicle-restriction-under-traffic-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159386.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">160</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">78</span> Sparse Signal Restoration Algorithm Based on Piecewise Adaptive Backtracking Orthogonal Least Squares</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linyu%20Wang">Linyu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiahui%20Ma"> Jiahui Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianhong%20Xiang"> Jianhong Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanyu%20Jiang"> Hanyu Jiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> the traditional greedy compressed sensing algorithm needs to know the signal sparsity when recovering the signal, but the signal sparsity in the practical application can not be obtained as a priori information, and the recovery accuracy is low, which does not meet the needs of practical application. To solve this problem, this paper puts forward Piecewise adaptive backtracking orthogonal least squares algorithm. The algorithm is divided into two stages. In the first stage, the sparsity pre-estimation strategy is adopted, which can quickly approach the real sparsity and reduce time consumption. In the second stage iteration, the correction strategy and adaptive step size are used to accurately estimate the sparsity, and the backtracking idea is introduced to improve the accuracy of signal recovery.

It is demonstrated that under OFC mode without other optimisation, brake mean effective pressure (BMEP) can meet the requirement at mid-high load, but it has a considerable decline at low load compared to conventional air combustion (CAC) mode. Moreover, there is a considerable deterioration in brake specific fuel consumption (BSFC) compared to that of CAC mode. A practical method is proposed to optimise the DFSI engine performance under OFC mode by changing intake charge components and utilising appropriate water injection (WI) strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxy-fuel%20combustion" title="oxy-fuel combustion">oxy-fuel combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=dual-fuel%20spark%20ignition%20engine" title=" dual-fuel spark ignition engine"> dual-fuel spark ignition engine</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=gasoline" title=" gasoline"> gasoline</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20simulation" title=" computer simulation"> computer simulation</a> </p> <a href="https://publications.waset.org/abstracts/150775/numerical-investigation-of-oxy-fuel-combustion-in-gasoline-engine-for-carbon-capture-and-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150775.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">91</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">75</span> Design of Reconfigurable Supernumerary Robotic Limb Based on Differential Actuated Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qinghua%20Zhang">Qinghua Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yanhe%20Zhu"> Yanhe Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiang%20Zhao"> Xiang Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeqin%20Yang"> Yeqin Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongwei%20Jing"> Hongwei Jing</a>, <a href="https://publications.waset.org/abstracts/search?q=Guoan%20Zhang"> Guoan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Zhao"> Jie Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a wearable reconfigurable supernumerary robotic limb with differential actuated joints, which is lightweight, compact and comfortable for the wearers.

The better effect of cow dung vermicompost (CV) on seed germination and seedling growth proved that cow dung was indeed the preferred additive in sludge vermicomposting as reported by plentiful researchers worldwide. The effects and the best amount of application of CV were further discussed. Results demonstrated that seed germination and seedling growth (seedlings number, plant height, stem diameter) were the best and heavy metal (Zn, Pb, Cr and As) contents of plant were the lowest when soil amended with CV by 15%. Additionally, CV fostered higher contents of chlorophyll a and chlorophyll b compared to the control when concentration ranged from 5 to 15%, thereafter a slight increase in chlorophyll content was observed form 15% to 25%. Thus, CV at the optimum proportion of 15% could serve as a feasible and satisfactory way of sludge agricultural utilization of sewage sludge. In summary, sewage sludge can be gainfully utilized in producing organic fertilizer via vermicomposting, thereby not only providing a means of sewage sludge treatment and disposal, but also stimulating the growth of plant and the ability to resist disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cow%20dung%20vermicompost" title="cow dung vermicompost">cow dung vermicompost</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20germination" title=" seed germination"> seed germination</a>, <a href="https://publications.waset.org/abstracts/search?q=seedling%20growth" title=" seedling growth"> seedling growth</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge%20utilization" title=" sludge utilization"> sludge utilization</a> </p> <a href="https://publications.waset.org/abstracts/59981/influence-of-agricultural-utilization-of-sewage-sludge-vermicompost-on-plant-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59981.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">262</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> A Deep Learning-Based Pedestrian Trajectory Prediction Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haozhe%20Xiang">Haozhe Xiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rise of the Internet of Things era, intelligent products are gradually integrating into people's lives. Pedestrian trajectory prediction has become a key issue, which is crucial for the motion path planning of intelligent agents such as autonomous vehicles, robots, and drones. In the current technological context, deep learning technology is becoming increasingly sophisticated and gradually replacing traditional models. The pedestrian trajectory prediction algorithm combining neural networks and attention mechanisms has significantly improved prediction accuracy. Based on in-depth research on deep learning and pedestrian trajectory prediction algorithms, this article focuses on physical environment modeling and learning of historical trajectory time dependence. At the same time, social interaction between pedestrians and scene interaction between pedestrians and the environment were handled. An improved pedestrian trajectory prediction algorithm is proposed by analyzing the existing model architecture. With the help of these improvements, acceptable predicted trajectories were successfully obtained.

Because of their nonstick, environmental, and economic benefits, foul-release nanocoatings have received a lot of attention. They use physical anti-adhesion terminology to deter any fouling attachment.Natural bioinspired surfaces have micro/nano-roughness and low surface free energy features, which may inspire the design of dynamic antifouling coatings. Graphene-based nanocomposite surfaces were designed to combat marine-fouling adhesion with ecological as well as eco-friendly effects rather than biocidal solutions. Polymer–graphenenanofiller hybrids are a novel class of composite materials in fouling-prevention applications. The controlled preparation of nanoscale orientation, arrangement, and direction along the composite building blocks would result in superior fouling prohibition. This work representsfoul-release nanocomposite top coats for marine coating applications with superhydrophobicity, surface inertness against fouling adherence, cost-effectiveness, and increased lifetime. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foul-release%20nanocoatings" title="foul-release nanocoatings">foul-release nanocoatings</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene-based%20nanocomposite" title=" graphene-based nanocomposite"> graphene-based nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofillers" title=" nanofillers"> nanofillers</a> </p> <a href="https://publications.waset.org/abstracts/149138/graphene-based-nanocomposites-as-ecofriendly-antifouling-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149138.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">141</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">65</span> Computational Analysis of the Scaling Effects on the Performance of an Axial Compressor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junting%20Xiang">Junting Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%B6rg%20Uwe%20Schl%C3%BCter"> Jörg Uwe Schlüter</a>, <a href="https://publications.waset.org/abstracts/search?q=Fei%20Duan"> Fei Duan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The miniaturization of gas turbines promises many advantages. Miniature gas turbines can be used for local power generation or the propulsion of small aircraft, such as UAV and MAV. However, experience shows that the miniaturization of conventional gas turbines, which are optimized at their current large size, leads to a substantial loss of efficiency and performance at smaller scales. This may be due to a number of factors, such as the Reynolds-number effect, the increased heat transfer, and manufacturing tolerances. In the present work, we focus on computational investigations of the Reynolds number effect and the wall heat transfer on the performance of axial compressor during its size change. The NASA stage 35 compressors are selected as the configuration in this study and Computational Fluid Dynamics (CFD) is used to carry out the miniaturization process and simulations. We perform parameter studies on the effect of Reynolds number and wall thermal conditions. Our results indicate a decrease of efficiency, if the compressor is miniaturized based on its original geometry due to the increase of viscous effects. The increased heat transfer through wall has only a small effect and will actually benefit compressor performance based on our study. <p class="card-text"><strong>Keywords:</strong> <a
