UGKS is a direct modeling method for both continuum and rarefied flow computations. The dynamics of particle and gas are described as rarefied and continuum flow, respectively. Therefore, we use the Bhatnagar-Gross-Krook (BGK) equation for the particle distribution function. For the gas phase, the gas kinetic scheme for Navier-Stokes equation is solved. The momentum transfer between gas and particle is achieved by the acceleration term added to the BGK equation. The new scheme is tested by a 2cm-in-thickness dense bed comprised of glass particles with 1.5mm in diameter, and reasonable agreement is achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas-particle%20flow" title="gas-particle flow">gas-particle flow</a>, <a href="https://publications.waset.org/abstracts/search?q=unified%20gas-kinetic%20scheme" title=" unified gas-kinetic scheme"> unified gas-kinetic scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=momentum%20transfer" title=" momentum transfer"> momentum transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=shock-induced%20fluidization" title=" shock-induced fluidization"> shock-induced fluidization</a> </p> <a href="https://publications.waset.org/abstracts/94993/unified-gas-kinetic-scheme-for-gas-particle-flow-in-shock-induced-fluidization-of-particles-bed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94993.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">325</span> A Watermarking Signature Scheme with Hidden Watermarks and Constraint Functions in the Symmetric Key Setting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanmin%20Zhao">Yanmin Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Siu%20Ming%20Yiu"> Siu Ming Yiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To claim the ownership for an executable program is a non-trivial task. An emerging direction is to add a watermark to the program such that the watermarked program preserves the original program’s functionality and removing the watermark would heavily destroy the functionality of the watermarked program. In this paper, the first watermarking signature scheme with the watermark and the constraint function hidden in the symmetric key setting is constructed. The scheme uses well-known techniques of lattice trapdoors and a lattice evaluation.

Reinterpreting the diachroneity of 'intertextuality' in the context of misreading theory extended the range of the 'intermediality' of transmedia to the intense tension between digital images and symbolic images throughout history of images. With the analogy between six categories of revisionary ratios and six steps of digital transformation, digital rhetoric might be illustrated as a linear process reflecting dynamic, intensive relations between digital moving images and original static images. Finally, it was concluded that two-way framework of the rhetoric of transformation of digital images and reversed served as a renarrative structure to revive static images by reconnecting them with digital moving images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhetoric" title="rhetoric">rhetoric</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20art" title=" digital art"> digital art</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediality" title=" intermediality"> intermediality</a>, <a href="https://publications.waset.org/abstracts/search?q=misreading%20theory" title=" misreading theory"> misreading theory</a> </p> <a href="https://publications.waset.org/abstracts/100230/rhetoric-and-renarrative-structure-of-digital-images-in-trans-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100230.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">256</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">323</span> Development of a Real Time Axial Force Measurement System and IoT-Based Monitoring for Smart Bearing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassam%20Ahmed">Hassam Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuanzhi%20Liu"> Yuanzhi Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yassine%20Selami"> Yassine Selami</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Tao"> Wei Tao</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Zhao"> Hui Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research is to develop a real time axial force measurement system for a smart bearing through the use of strain-gauges, whereby the data acquisition is performed by an Arduino microcontroller due to its easy manipulation and low-cost. The measured signal is acquired and then discretized using a Wheatstone Bridge and an Analog-Digital Converter (ADC) respectively. For bearing monitoring, a real time monitoring system based on Internet of things (IoT) and Bluetooth were developed. Experimental tests were performed on a bearing within a force range up to 600 kN.

A biomechanical model of the elbow joint can be built by the connection of muscle force model and elbow dynamics. But there are many undetermined coefficients in the model like the optimal joint angle and optimal muscle force which are usually specified as the experimental parameters of other workers. Because of the individual differences, there is a certain deviation of the final result. To this end, the RMS value of the deviation between the actual angle and calculated angle is considered. A set of coefficients which lead to the minimum RMS value will be chosen to be the optimal parameters. The direct search method and the conjugacy search method are used to get the optimal parameters, thus the model can be more accurate and mode adaptability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elbow%20biomechanical%20model" title="elbow biomechanical model">elbow biomechanical model</a>, <a href="https://publications.waset.org/abstracts/search?q=RMS" title=" RMS"> RMS</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20search" title=" direct search"> direct search</a>, <a href="https://publications.waset.org/abstracts/search?q=conjugacy%20search" title=" conjugacy search"> conjugacy search</a> </p> <a href="https://publications.waset.org/abstracts/7188/an-elbow-biomechanical-model-and-its-coefficients-adjustment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7188.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">549</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">320</span> Synthesis of SnO Novel Cabbage Nanostructure and Its Electrochemical Property as an Anode Material for Lithium Ion Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongkui%20Cui">Yongkui Cui</a>, <a href="https://publications.waset.org/abstracts/search?q=Fengping%20Wang"> Fengping Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hailei%20Zhao"> Hailei Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zubair%20Iqbal"> Muhammad Zubair Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziya%20Wang"> Ziya Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Li"> Yan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Pengpeng%20LV"> Pengpeng LV</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The novel 3D SnO cabbages self-assembled by nanosheets were successfully synthesized via template-free hydrothermal growth method under facile conditions.The XRD results manifest that the as-prepared SnO is tetragonal phase.

Further, this study summarizes the types of the old urban area and proposes space renewal strategies for three typical old urban areas, such as old residential area, old factory and old market. These old urban areas are confronted with the problems of functional layout confounding, lack of infrastructure and poor living environment.

Much attention has been focused on the output impedance of the Howland circuit. Here we focus on the maximum load of the Howland source and discuss the relationship between the circuit parameters at maximum load. We conclude that the signal input terminal of the feedback resistor should be as large as possible, but that the current-limiting resistor should be smaller. The op-amp saturation voltage should also be high. The bandwidth of the circuit is proportional to the bandwidth of the op-amp. The Howland current pump was simulated using multisim12. When the AD8066AR was selected as the op-amp, the maximum load was 11.5 kΩ, and the Howland current pump had a stable output ipp to 2mAp up to 200 kHz. However, with an OPA847 op-amp and a load of 6.3 kΩ, the output current was also stable, and the frequency was as high as 3 MHz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-impedance" title="bio-impedance">bio-impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=improved%20Howland%20current%20pump" title=" improved Howland current pump"> improved Howland current pump</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20characteristics" title=" load characteristics"> load characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=bioengineering" title=" bioengineering"> bioengineering</a> </p> <a href="https://publications.waset.org/abstracts/3294/load-characteristics-of-improved-howland-current-pump-for-bio-impedance-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3294.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">514</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">311</span> Mechanical Properties and Microstructure of Ultra-High Performance Concrete Containing Fly Ash and Silica Fume</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jisong%20Zhang">Jisong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yinghua%20Zhao"> Yinghua Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study investigated the mechanical properties and microstructure of Ultra-High Performance Concrete (UHPC) containing supplementary cementitious materials (SCMs), such as fly ash (FA) and silica fume (SF), and to verify the synergistic effect in the ternary system.

When the coagulant ions mix with a humic acid solution, a Fluorescence quenching effect may be observed conditionally. This effect can be described by Stern-Volmer linear equation which can be used for quantifying the quenching value (Kq) of the Fluorescence quenching effect. In addition, a Complex-Formation Titration (CFT) theory was conducted and the result was used to explain the electron-neutralization capability of the coagulant (AlCl₃) at different pH. The results indicated that when pH of the ACl₃ solution was between 6 and 8, fluorescence quenching effect obviously occurred. The maximum Kq value was found to be 102,524 at pH 6. It means that the higher the Kq value is, the better complex reaction between a humic acid and aluminum salts will be. Through the Kq value study, the optimum pH can be quantified when the humic acid solution is coagulated with aluminum ions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=humic%20acid" title="humic acid">humic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence%20quenching%20effect" title=" fluorescence quenching effect"> fluorescence quenching effect</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20reaction" title=" complex reaction"> complex reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=titration" title=" titration"> titration</a> </p> <a href="https://publications.waset.org/abstracts/92882/finding-the-reaction-constant-between-humic-acid-and-aluminum-ion-by-fluorescence-quenching-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92882.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">578</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">305</span> The Location-Routing Problem with Pickup Facilities and Heterogeneous Demand: Formulation and Heuristics Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mao%20Zhaofang">Mao Zhaofang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Yida"> Xu Yida</a>, <a href="https://publications.waset.org/abstracts/search?q=Fang%20Kan"> Fang Kan</a>, <a href="https://publications.waset.org/abstracts/search?q=Fu%20Enyuan"> Fu Enyuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Zhao"> Zhao Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, last-mile distribution plays an increasingly important role in the whole industrial chain delivery link and accounts for a large proportion of the whole distribution process cost. Promoting the upgrading of logistics networks and improving the layout of final distribution points has become one of the trends in the development of modern logistics. Due to the discrete and heterogeneous needs and spatial distribution of customer demand, which will lead to a higher delivery failure rate and lower vehicle utilization, last-mile delivery has become a time-consuming and uncertain process. As a result, courier companies have introduced a range of innovative parcel storage facilities, including pick-up points and lockers. The introduction of pick-up points and lockers has not only improved the users’ experience but has also helped logistics and courier companies achieve large-scale economy. Against the backdrop of the COVID-19 of the previous period, contactless delivery has become a new hotspot, which has also created new opportunities for the development of collection services. Therefore, a key issue for logistics companies is how to design/redesign their last-mile distribution network systems to create integrated logistics and distribution networks that consider pick-up points and lockers. This paper focuses on the introduction of self-pickup facilities in new logistics and distribution scenarios and the heterogeneous demands of customers. In this paper, we consider two types of demand, including ordinary products and refrigerated products, as well as corresponding transportation vehicles. We consider the constraints associated with self-pickup points and lockers and then address the location-routing problem with self-pickup facilities and heterogeneous demands (LRP-PFHD). To solve this challenging problem, we propose a mixed integer linear programming (MILP) model that aims to minimize the total cost, which includes the facility opening cost, the variable transport cost, and the fixed transport cost. Due to the NP-hardness of the problem, we propose a hybrid adaptive large-neighbourhood search algorithm to solve LRP-PFHD. We evaluate the effectiveness and efficiency of the proposed algorithm by using instances generated based on benchmark instances. The results demonstrate that the hybrid adaptive large neighbourhood search algorithm is more efficient than MILP solvers such as Gurobi for LRP-PFHD, especially for large-scale instances. In addition, we made a comprehensive analysis of some important parameters (e.g., facility opening cost and transportation cost) to explore their impacts on the results and suggested helpful managerial insights for courier companies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=city%20logistics" title="city logistics">city logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=last-mile%20delivery" title=" last-mile delivery"> last-mile delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=location-routing" title=" location-routing"> location-routing</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20large%20neighborhood%20search" title=" adaptive large neighborhood search"> adaptive large neighborhood search</a> </p> <a href="https://publications.waset.org/abstracts/181563/the-location-routing-problem-with-pickup-facilities-and-heterogeneous-demand-formulation-and-heuristics-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181563.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">78</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">304</span> Mean Square Responses of a Cantilever Beam with Various Damping Mechanisms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaping%20Zhao">Yaping Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yimin%20Zhang"> Yimin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present paper, the stationary random vibration of a uniform cantilever beam is investigated. Two types of damping mechanism, i.e. the external and internal viscous dampings, are taken into account simultaneously. The excitation form is the support motion, and it is ideal white. Because two type of damping mechanism are considered concurrently, the product of the modal damping ratio and the natural frequency is not a constant anymore. As a result, the infinite definite integral encountered in the process of computing the mean square response is more complex than that in the existing literature. One signal progress of this work is to have calculated these definite integrals accurately. The precise solution of the mean square response is thus obtained in the infinite series form finally.

Moreover, the comovement in reputation risk is attenuated during the COVID-19 pandemic. Further analyses suggest that the reduction in comovement varies by state-level partisanship and death rate during the pandemic. Comovement in reputation risk declines more significantly in the Democratic states with stringent social distancing policies and in states with higher infection severity.

This technique is especially promising in the area of rapid automated damage detection and quantification. In collaboration with a major industry partner from the aerospace sector advanced thermography-based NDT software for impact damaged composites is introduced. The software is based on correlation analysis of time-temperature profiles in combination with an image enhancement process. The prototype software is aiming to a) better visualise the damages in a relatively easy-to-use way and b) automatically and quantitatively measure the properties of the degradation. Knowing that degradation properties play an important role in the identification of degradation types, tests and results on specimens which were artificially damaged have been performed and analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NDT" title="NDT">NDT</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation%20analysis" title=" correlation analysis"> correlation analysis</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=damage" title=" damage"> damage</a>, <a href="https://publications.waset.org/abstracts/search?q=inspection" title=" inspection"> inspection</a> </p> <a href="https://publications.waset.org/abstracts/30959/a-comparative-assessment-of-industrial-composites-using-thermography-and-ultrasound" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30959.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">547</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">300</span> Gaussian Particle Flow Bernoulli Filter for Single Target Tracking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyeongbok%20Kim">Hyeongbok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Lingling%20Zhao"> Lingling Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaohong%20Su"> Xiaohong Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Junjie%20Wang"> Junjie Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Bernoulli filter is a precise Bayesian filter for single target tracking based on the random finite set theory.

The accuracy of traditional software requirements elicitation methods is not sufficient, so this study attempts to use a multi-perspective based requirements heuristic framework. Methods such as interview and questionnaire combination, card sorting, and model driven are proposed. The collection results from PCA show that the new methods can better help with requirements elicitation. However, the method has some limitations and, there are some efficiency issues.

It is found that the radius of caverns should be around half of the span width (i.e., B/R=2) to reduce vertical displacement at the crown of cavern. The smaller the rock cover, the smaller displacement. The minimum rock thickness should be at least the same as the cavern span to eliminate excessive yielded element.

In the case of naturally evolved enzymes, one may consider the active site residues as the musicians in the enzyme orchestra, while the metal can be considered as their concertmaster. Together they catalyze reactions as if they performed a masterpiece written by nature. The Lactonase can be thought as a member of the amidohydrolase family, with two concertmasters, Fe and Zn, at its active site. It catalyzes the quorum sensing signal- N-acyl homoserine lactones (AHLs or N-AHLs)- by hydrolyzing the lactone ring. This process, known as quorum quenching, provides a strategy in the treatment of infectious diseases without introducing selection pressure. However, the activity of lactonase is metal-dependent, and this dependence hampers the clinic usage. In our study, we use the empirical valence bond (EVB) approach to evaluate the catalytic contributions decomposing them to electrostatic and other components. <p
