In the 1980s, China was going through a series of changes and transformations; the wounds and scars from the Cultural Revolution, a freer literary atmosphere then, and the introduction of Western thoughts into China gave rise to a trend of penning the ugly and the repulsive among writers. Such trend of utilizing 'Ugliness' as a theme of writing in Chinese literature is especially observed among Xianfeng writers (China’s pioneer writers or avant-garde writers). As a prominent Xianfeng writer, Su Tong (1963-) also incorporates ugliness into his novels: shoddy environment, degenerate and ruthless society, distorted and decadent humanity are part and parcel of his deliberate efforts of exploring and depicting the ugly aspects of the world. His full-length novel Rice, staging the appalling protagonist Five Dragons, is a prime example. In fact, all characters in Rice exhibit Ugliness but Five Dragons’s turning into a figure of ugly spite is the most thorough and complete, making Rice a masterpiece of Su Tong’s art in projecting the Ugliness embedded in society and human nature. Approaching Rice from the angle of the aesthetics of the Ugly and selecting Five Dragons as the subject of close reading and analysis, this paper offers insights into both Su Tong’s distinct style of foregrounding and unfolding Ugliness in his novel and the workings of such text when he deploys the Ugly as a center component of his writing. In addition to citing from the discussion of Rice by literary critics and the author himself, this paper also presents textual evidence and analyzes the imageries/motifs and calculated vocabulary/narration employed by Su Tong to illustrate how Five Dragons' extreme behaviors and psychological states are integral to the plot and ultimately to the manifestation of ugliness as the novel’s theme. This study reveals that although the psyche and doings of Five Dragons and other 'ugly' characters are, as the author once stated, imagined products of the writer Su Tong himself, Rice sheds light onto the ugly aspects of life in China in 1920s-30s. Three aspects of Ugliness are identified and discussed in the paper. Lastly, this paper also suggests some effects of Su Tong’s exploration of Ugliness in Rice, proposing that the portrayal of Ugliness per se is not the ends of Su Tong’s mastery of the aesthetics of the Ugly but rather a means to making his writing transcend from provoking spontaneous moral judgment in readers on the doings of Five Dragons to prompting readers to ponder on philosophical questions such as how humanity can still be possible when an individual confronts the dark sides of a self, a society, and his/her fate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aesthetics" title="aesthetics">aesthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=Rice" title=" Rice"> Rice</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Tong" title=" Su Tong"> Su Tong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugly" title=" Ugly"> Ugly</a> </p> <a href="https://publications.waset.org/abstracts/100710/exploring-ugliness-as-an-aesthetic-theme-in-contemporary-chinese-literature-through-analyzing-five-dragons-protagonist-in-rice-by-xianfeng-writer-su-tong" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100710.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">169</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> Pushover Experiment of Traditional Dieh-Dou Timber Frame </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ren%20Zuo%20Wang">Ren Zuo Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, in order to investigate the joint behaviors of the Dieh-Dou structure.

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. 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> </p> <a href="https://publications.waset.org/abstracts/164028/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/164028.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">104</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> Acoustic Radiation from an Infinite Cylindrical Shell with Periodic Lengthwise Ribs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yunzhe%20Tong">Yunzhe Tong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Fan"> Jun Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Wang"> Bin Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The vibroacoustic behavior of an immersed infinite cylindrical shell with periodic lengthwise ribs has been studied in this paper. The motions of the shell are described by the Donnell equations. Each lengthwise rib is modeled as an elastic beam. The motions of the bulkheads are decomposed into the longitudinal motions and flexural motions. The analytical expressions of the shell motions can be obtained through circumferential mode expansion, Fourier Transform and periodic boundary condition in the circumferential direction. Furthermore, the far-field radiated pressure has been obtained using the stationary phase. The analysis of wavenumber domain shows that periodic lengthwise stiffeners in the circumferential direction can produce flexural Bloch waves. The dominant feature in far-field pressure amplitude is the resonance of the supersonic components of the flexural Bloch waves in the circumferential direction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexural%20Bloch%20wave" title="flexural Bloch wave">flexural Bloch wave</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffened%20shell" title=" stiffened shell"> stiffened shell</a>, <a href="https://publications.waset.org/abstracts/search?q=vibroacoustics" title=" vibroacoustics"> vibroacoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=wavenumber%20analysis" title=" wavenumber analysis"> wavenumber analysis</a> </p> <a href="https://publications.waset.org/abstracts/90699/acoustic-radiation-from-an-infinite-cylindrical-shell-with-periodic-lengthwise-ribs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90699.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">209</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> Finite Element Analysis of Low-Velocity Impact Damage on Stiffened Composite Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuan%20Sun">Xuan Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mingbo%20Tong"> Mingbo Tong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To understand the factors which affect impact damage on composite structures, particularly the effects of impact position and ribs.

The structural elements chosen for the investigation comprised a series of stiffened composite panels, representative of real aircraft structure. By impacting the panels at different positions relative to the ribs, the effect of relative position of ribs was found out. Then the simulation results and the experiments data were compared.

In this study, the dispersion characteristics and wave structures of Stoneley waves in elastic multilayered plates are displayed and investigated. With a perspective of bulk wave, a reasonable assumption of the potential function forms of the expansion wave and shear wave in nth layer medium is adopted, and the characteristic equation of Stoneley waves in a three-layered plate is given in a determinant form. The dispersion curves and wave structures are solved and presented in both numerical and simulation results. It is observed that two Stoneley wave modes exist in a three-layered plate, that conspicuous dispersion occurs on low frequency band, that the velocity of each Stoneley wave mode approaches the corresponding Stoneley wave velocity at interface between two half infinite spaces. The wave structures reveal that the in-plane displacement of Stoneley waves are relatively high at interfaces, which shows great potential for interface defects detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic%20equation" title="characteristic equation">characteristic equation</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20waves" title=" interface waves"> interface waves</a>, <a href="https://publications.waset.org/abstracts/search?q=potential%20function" title=" potential function"> potential function</a>, <a href="https://publications.waset.org/abstracts/search?q=Stoneley%20waves" title=" Stoneley waves"> Stoneley waves</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20structure" title=" wave structure"> wave structure</a> </p> <a href="https://publications.waset.org/abstracts/45214/investigation-of-stoneley-waves-in-multilayered-plates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45214.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">319</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> Reliable Soup: Reliable-Driven Model Weight Fusion on Ultrasound Imaging Classification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shuge%20Lei">Shuge Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Haonan%20Hu"> Haonan Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dasheng%20Sun"> Dasheng Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Huabin%20Zhang"> Huabin Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kehong%20Yuan"> Kehong Yuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Dai"> Jian Dai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Tong"> Yan Tong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It remains challenging to measure reliability from classification results from different machine learning models. This paper proposes a reliable soup optimization algorithm based on the model weight fusion algorithm Model Soup, aiming to improve reliability by using dual-channel reliability as the objective function to fuse a series of weights in the breast ultrasound classification models. Experimental results on breast ultrasound clinical datasets demonstrate that reliable soup significantly enhances the reliability of breast ultrasound image classification tasks. The effectiveness of the proposed approach was verified via multicenter trials. The results from five centers indicate that the reliability optimization algorithm can enhance the reliability of the breast ultrasound image classification model and exhibit low multicenter correlation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20ultrasound%20image%20classification" title="breast ultrasound image classification">breast ultrasound image classification</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20attribution" title=" feature attribution"> feature attribution</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20assessment" title=" reliability assessment"> reliability assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20optimization" title=" reliability optimization"> reliability optimization</a> </p> <a href="https://publications.waset.org/abstracts/176773/reliable-soup-reliable-driven-model-weight-fusion-on-ultrasound-imaging-classification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176773.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">85</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">66</span> Remote Electroacupuncture Analgesia at Contralateral LI4 Acupoint in Complete Freund's Adjuvant-Induced Inflammatory Hindpaw Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tong-Chien%20Wu">Tong-Chien Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Liang%20Hsieh"> Ching-Liang Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Wen%20Lin"> Yi-Wen Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are accumulating evidences surrounding the therapeutic effect of electroacupuncture (EA). Local EA can reliably attenuate inflammatory pain in mouse with unclear mechanisms. However, the effect of EA on distal and contralateral acupoint for pain control has been rarely studied and the result was controversial. Here in our study, we found that inflammatory hindpaw pain in mouth, which was induced by injecting the complete Freund’s adjuvant (CFA) 2 days ago can be alleviated immediately after 2Hz 15mins EA treatment at contralateral forefoot acupoint LI4 through both mechanic and thermal behavior test, while sham acupoint group is not. The efficacy was observed to be more obvious after the second round of EA treatment on the following day. This analgesic effect is produced by applying EA to a site remote from the painful area. The present study provides a powerful experimental animal model that can be used for investigating the unique physiological mechanisms involved in acupuncture analgesia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=remote%20electroacupuncture" title="remote electroacupuncture">remote electroacupuncture</a>, <a href="https://publications.waset.org/abstracts/search?q=distal%20EA" title=" distal EA"> distal EA</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20control" title=" pain control"> pain control</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammation" title=" anti-inflammation"> anti-inflammation</a> </p> <a href="https://publications.waset.org/abstracts/85446/remote-electroacupuncture-analgesia-at-contralateral-li4-acupoint-in-complete-freunds-adjuvant-induced-inflammatory-hindpaw-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85446.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">187</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> Language Developmental Trends of Mandarin-Speaking Preschoolers in Beijing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nga%20Yui%20Tong">Nga Yui Tong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mandarin, the official language of China, is based on the Beijing dialect and is spoken by more than one billion people from all over the world. To investigate the trends of Mandarin acquisition, 192 preschoolers are recruited by stratified random sampling. They are from 4 different districts in Beijing, 2 schools in each district, with 4 age groups, both genders, and 3 children in each stratum. The children are paired up to conduct semi-structured free play for 30 minutes. Their language output is videotaped, transcribed, and coded for the calculation of Mean Length of Utterance (MLU). Two-way ANOVA showed that the variation of MLU is significantly contributed by age, which is coherent to previous findings of other languages. This first large-scale study to investigate the developmental trend of Mandarin in young children in Beijing provides empirical evidence to the development of standards and curriculum planning for early Mandarin education. Interestingly, the gender effect in the study is insignificant, with boys showing a slightly higher MLU than girls across all age groups and settings, except the 4.5 years same-gender dyads. The societal factors in the Chinese context on parenting and gender bias are worth looking into. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beijing" title="Beijing">Beijing</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20development" title=" language development"> language development</a>, <a href="https://publications.waset.org/abstracts/search?q=Mandarin" title=" Mandarin"> Mandarin</a>, <a href="https://publications.waset.org/abstracts/search?q=preschoolers" title=" preschoolers"> preschoolers</a> </p> <a href="https://publications.waset.org/abstracts/114658/language-developmental-trends-of-mandarin-speaking-preschoolers-in-beijing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114658.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">120</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> Study on Constitutive Model of Particle Filling Material Considering Volume Expansion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xu%20Jinsheng">Xu Jinsheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong%20Xin"> Tong Xin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zheng%20Jian"> Zheng Jian</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhou%20Changsheng"> Zhou Changsheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The NEPE (nitrate ester plasticized polyether) propellant is a kind of particle filling material with relatively high filling fraction.

In this paper, a series of mechanical testing in inclusion with CCD technique were conducted to analyze the evolution of internal defects of propellant. The volume expansion function of the particle filling material was established by measuring of longitudinal and transverse strain with optical deformation measurement system. By analyzing the defects and internal damages of the material, a visco-hyperelastic constitutive model based on free energy theory was proposed incorporating damage function.

In doing so, they investigated whether threatened identities depend on whether people are excluded by ingroup members (same ethnic background) or outgroup members (another ethnic background), as exclusion studies have shown mixed results when it comes to being excluded by ingroup versus outgroup members. For this purpose, students in Singapore and in the Netherlands participated in an online ball-tossing game (Cyberball) where they were excluded or included by other players with either the same or other ethnicity. Tentative results showed that both Singaporean and Dutch participants reported a more threat to their group identity than to their personal identity following exclusion and this did not depend on who excluded them. These tentative findings suggest that threatened identities following exclusion may not depend on cultural factors or on the source of exclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultures" title="cultures">cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=exclusion" title=" exclusion"> exclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment" title=" experiment"> experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20membership" title=" group membership"> group membership</a>, <a href="https://publications.waset.org/abstracts/search?q=identities" title=" identities"> identities</a> </p> <a href="https://publications.waset.org/abstracts/123621/personal-identity-and-group-identity-under-threat-following-exclusion-a-study-in-singapore-and-in-the-netherlands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123621.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">62</span> Rapid Generation of Octagonal Pyramids on Silicon Wafer for Photovoltaics by Swift Anisotropic Chemical Etching Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20Iqbal">Sami Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Hussain"> Azam Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiping%20Wu"> Weiping Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guo%20Xinli"> Guo Xinli</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong%20Zhang"> Tong Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel octagonal upright micro-pyramid structure was generated by wet chemical anisotropic etching on a monocrystalline silicon wafer (100).

Under rigorous control and observation, the etching process' response time was maintained precisely. The experimental outcomes show a significant decrease in the optical surface reflectance of silicon wafers, with the lowest reflectance of 8.98%, as well as enhanced surface structure, periodicity, and surface area coverage of more than 85%.

Digital twin technology has obvious advantages in the simulation of life cycle models of aerospace satellite navigation products. In order to meet the increasing demand, this paper builds a Beidou-3 satellite navigation digital twin platform (BDSDTP). The basic establishment of BDSDTP was completed by establishing a digital twin double, Beidou-3 comprehensive digital twin design, predictive maintenance (PdM) mathematical model, and visual interaction design.

The goal of this research is to develop a horizontal road transition design tool that considers the transition technology of traffic capacity consistency to explore its accommodation mechanism. The influencing factors of capacity are synthesized and a modified capacity calculation model focusing on the influence of road width and lateral clearance is developed based on the VISSIM simulation to calculate the width of road transition sections. To keep the traffic capacity consistency, the right side of the transition section of the tunnel entrance and exit is divided into three parts: front arc, an intermediate transition section, and end arc; an optimization design on each transition part is conducted to improve the capacity stability and horizontal alignment transition.

However, the human eye will feel uncomfortable and it will occur diplopia if horizontal parallax is larger than eye separation. Therefore, we need to do parallax refining before conducting stereoscopic observation. Although some scholars have been devoted to online remote sensing refining, the main work of image refining is completed on the server side. There will be a significant delay when multiple users access the server at the same time. The emergence of HTML5 technology in recent years makes it possible to develop rich browser web application. Authors complete the image parallax refining on the browser side based on HTML5, while server side only need to transfer image data and parallax file to browser side according to the browser’s request. In this way, we can greatly reduce the server CPU load and allow a large number of users to access server in parallel and respond the user’s request quickly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20remote%20sensing%20images" title="3D remote sensing images">3D remote sensing images</a>, <a href="https://publications.waset.org/abstracts/search?q=parallax" title=" parallax"> parallax</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20refining" title=" online refining"> online refining</a>, <a href="https://publications.waset.org/abstracts/search?q=rich%20browser%20web%20application" title=" rich browser web application"> rich browser web application</a>, <a href="https://publications.waset.org/abstracts/search?q=HTML5" title=" HTML5"> HTML5</a> </p> <a href="https://publications.waset.org/abstracts/19927/3d-remote-sensing-images-parallax-refining-based-on-html5" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19927.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">461</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">58</span> Joule Self-Heating Effects and Controlling Oxygen Vacancy in La₀.₈Ba₀.₂MnO₃ Ultrathin Films with Nano-Sized Labyrinth Morphology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guankai%20Lin">Guankai Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Tong"> Wei Tong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Zhu"> Hong Zhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The electric current induced Joule heating effects have been investigated in La₀.₈Ba₀.₂MnO₃ ultrathin films deposited on LaAlO₃(001) single crystal substrate with smaller lattice constant by using the sol-gel method. By applying moderate bias currents (~ 10 mA), it is found that Joule self-heating simply gives rise to a temperature deviation between the thermostat and the test sample, but the intrinsic ρ(T) relationship measured at a low current (0.1 mA) changes little. However, it is noteworthy that the low-temperature transport behavior degrades from metallic to insulating state after applying higher bias currents ( > 31 mA) in a vacuum. Furthermore, metallic transport can be recovered by placing the degraded film in air. The results clearly suggest that the oxygen vacancy in the La₀.₈Ba₀.₂MnO₃ films is controllable in different atmospheres, particularly with the aid of the Joule self-heating. According to the SEM images, we attribute the controlled oxygen vacancy to the nano-sized labyrinth pattern of the films, where the large surface-to-volume ratio plays a curial role. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=controlling%20oxygen%20vacancy" title="controlling oxygen vacancy">controlling oxygen vacancy</a>, <a href="https://publications.waset.org/abstracts/search?q=joule%20self-heating" title=" joule self-heating"> joule self-heating</a>, <a href="https://publications.waset.org/abstracts/search?q=manganite" title=" manganite"> manganite</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel%20method" title=" sol-gel method"> sol-gel method</a> </p> <a href="https://publications.waset.org/abstracts/118376/joule-self-heating-effects-and-controlling-oxygen-vacancy-in-la08ba02mno3-ultrathin-films-with-nano-sized-labyrinth-morphology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118376.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">153</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> Path Planning for Multiple Unmanned Aerial Vehicles Based on Adaptive Probabilistic Sampling Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Long%20Cheng">Long Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong%20He"> Tong He</a>, <a href="https://publications.waset.org/abstracts/search?q=Iraj%20Mantegh"> Iraj Mantegh</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Fang%20Xie"> Wen-Fang Xie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Path planning is essential for UAVs (Unmanned Aerial Vehicle) with autonomous navigation in unknown environments.

Considering that the optimum conditions for each stage can be diverse diverse, the development of a multi-stage AD system is likely to the AD efficiency through individual optimization. In this research, we developed a highly integrate three-stage anaerobic digester (HM3) to combine the advantages of dry AD and wet AD for anaerobic co-digestion of food waste and horse manure. The digester design comprised mainly of three chambers - high-solids hydrolysis, high-solids acidogenesis and wet methanogensis. Through comparing the treatment performance with other two control digesters, HM3 presented 11.2 ~22.7% higher methane yield. The improved methane yield was mainly attributed to the functionalized partitioning in the integrated digester, which significantly accelerated the solubilization of solid organic matters and the formation of organic acids, as well as ammonia in the high-solids hydrolytic and acidogenic stage respectively. Additionally, HM3 also showed the highest volatile solids reduction rate among the three digesters. Real-time PCR and pyrosequencing analysis indicated that the abundance and biodiversity of microorganisms including bacteria and archaea in HM3 was much higher than that in the control reactors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=high-solids" title=" high-solids"> high-solids</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste%20and%20horse%20manure" title=" food waste and horse manure"> food waste and horse manure</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20community" title=" microbial community"> microbial community</a> </p> <a href="https://publications.waset.org/abstracts/37897/three-stage-anaerobic-co-digestion-of-high-solids-food-waste-and-horse-manure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37897.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">414</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> Artificial Neurons Based on Memristors for Spiking Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yan%20Yu">Yan Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Yu"> Wang Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Xintong"> Chen Xintong</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Yi"> Liu Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Yanzhong"> Zhang Yanzhong</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Yanji"> Wang Yanji</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Xingyu"> Chen Xingyu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Miaocheng"> Zhang Miaocheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Tong%20Yi"> Tong Yi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Neuromorphic computing based on spiking neural networks (SNNs) has emerged as a promising avenue for building the next generation of intelligent computing systems. Owing to its high-density integration, low power, and outstanding nonlinearity, memristors have attracted emerging attention on achieving SNNs. However, fabricating a low-power and robust memristor-based spiking neuron without extra electrical components is still a challenge for brain-inspired systems. In this work, we demonstrate a TiO₂-based threshold switching (TS) memristor to emulate a leaky integrate-and-fire (LIF) neuron without auxiliary circuits, used to realize single layer fully connected (FC) SNNs. Moreover, our TiO₂-based resistive switching (RS) memristors realize spiking-time-dependent-plasticity (STDP), originating from the Ag diffusion-based filamentary mechanism.

Due to its special geographical location, mountain-plain transition zones are limited by many factors such as topography, mountain forest protection, etc., and their ecology is also more sensitive, with the characteristics of disaster susceptibility and resource gradient. Taking Dujiangyan City, Chengdu as an example, this paper establishes resilience evaluation indicators on the basis of ecological suitability evaluation through the analysis of current situation data and relevant policies: water conservation evaluation, soil and water conservation evaluation, biodiversity evaluation, soil erosion sensitivity evaluation, etc. Based on GIS spatial analysis, the ecological suitability and resilience evaluation results of Dujiangyan city were obtained by disjunction operation. The ecological resilience level of Dujiangyan city was divided into three categories: high, medium and low, with an area ratio of 50.81%, 16.4% and 32.79%, respectively.

Although platelets lack a nucleus, previous studies have shown that PPARγ agonists, rosiglitazone, inhibited platelet activation induced by collagen. In this study, we investigated the inhibitory effects of KR-62980, a newly synthesized PPARγ agonist, on collagen receptor-stimulated platelet activation. The specific tyrosine phosphorylations of key components (Syk, Vav1, Btk and PLCγ2) for collagen receptor signaling pathways were suppressed by KR-62980. KR-62980 also attenuated downstream responses including cytosolic calcium elevation, P-selectin surface exposure, and integrin αIIbβ3 activation. PPARγ was found to associate with multiple proteins within the LAT signaling complex in collagen-stimulated platelets. This association was prevented by KR-62980, indicating a potential mechanism for PPARγ function in collagen-stimulated platelet activation. Furthermore, KR-62980 inhibited platelet aggregation and adhesion in response to collagen in vitro and prolonged in vivo thrombotic response in carotid arteries of mice. Collectively, these data suggest that KR-62980 inhibits collagen-stimulated platelet activation and thrombus formation through modulating the collagen receptor signaling pathways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=KR-62980" title="KR-62980">KR-62980</a>, <a href="https://publications.waset.org/abstracts/search?q=PPAR%CE%B3" title=" PPARγ"> PPARγ</a>, <a href="https://publications.waset.org/abstracts/search?q=antiplatelet" title=" antiplatelet"> antiplatelet</a>, <a href="https://publications.waset.org/abstracts/search?q=thrombosis" title=" thrombosis"> thrombosis</a> </p> <a href="https://publications.waset.org/abstracts/47842/inhibitory-effects-of-ppargh-ligand-kr-62980-on-collagen-stimulated-platelet-activation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47842.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">333</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">49</span> Obstacle Avoidance Using Image-Based Visual Servoing Based on Deep Reinforcement Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tong%20He">Tong He</a>, <a href="https://publications.waset.org/abstracts/search?q=Long%20Chen"> Long Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Irag%20Mantegh"> Irag Mantegh</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Fang%20Xie">Wen-Fang Xie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes an image-based obstacle avoidance and tracking target identification strategy in GPS-degraded or GPS-denied environment for an Unmanned Aerial Vehicle (UAV). The traditional force algorithm for obstacle avoidance could produce local minima area, in which UAV cannot get away obstacle effectively. In order to eliminate it, an artificial potential approach based on harmonic potential is proposed to guide the UAV to avoid the obstacle by using the vision system. And image-based visual servoing scheme (IBVS) has been adopted to implement the proposed obstacle avoidance approach. In IBVS, the pixel accuracy is a key factor to realize the obstacle avoidance. In this paper, the deep reinforcement learning framework has been applied by reducing pixel errors through constant interaction between the environment and the agent. In addition, the combination of OpenTLD and Tensorflow based on neural network is used to identify the type of tracking target.

To highlight the effect of small pre-strain on fatigue properties of HTPB propellant, quasi-static stretching was carried out before fatigue loading, and uniaxial tensile tests at constant strain rates were successively applied. The results reveal that flow stress of propellant increases with reduction in temperature and rise in strain rate, and the strain rate-temperature equivalence relationship could be described by TTSP (time-temperature superposition principle) incorporating a modified WLF equation. Moreover, the rate of performance degradations and damage accumulation of propellant during fatigue tests increased with increasing strain amplitude and loading frequencies, while initial quasi-static loading has a negative effect on fatigue properties by comparing stress-strain relations after fatigue tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatigue" title="fatigue">fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=HTPB%20propellant" title=" HTPB propellant"> HTPB propellant</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20properties" title=" tensile properties"> tensile properties</a>, <a href="https://publications.waset.org/abstracts/search?q=time-temperature%20superposition%20principle" title=" time-temperature superposition principle"> time-temperature superposition principle</a> </p> <a href="https://publications.waset.org/abstracts/70854/the-mechanical-response-of-a-composite-propellant-under-harsh-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70854.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">293</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> Rating the Importance of Customer Requirements for Green Product Using Analytic Hierarchy Process Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lara%20F.%20Horani">Lara F.

Most of design methodologies focus on traditional requirements. But in the previous decade, the green products and the environment requirements have increasingly attracted the attention with the constant increase in the level of consumer awareness towards environmental problems (such as green-house effect, global warming, pollution and energy crisis, and waste management). Determining the importance weights for the customer requirements is an essential and crucial process. This paper used the analytic hierarchy process (AHP) approach to evaluate and rate the customer requirements for green products. With respect to the ultimate goal of customer satisfaction, surveys are conducted using a five-point scale analysis. With the help of this scale, one can derive the weight vectors. This approach can improve the imprecise ranking of customer requirements inherited from studies based on the conventional AHP. Furthermore, the AHP with extent analysis is simple and easy to implement to prioritize customer requirements. The research is based on collected data through a questionnaire survey conducted over a sample of 160 people belonging to different age, marital status, education and income groups in order to identify the customer preferences for green product requirements. <p class="card-text"><strong>Keywords:</strong> <a
