In the world, all countries attach great importance to the coastal zone management and the coastal zone economy. In China, the government has developed a number of related coastal management policies and institutional, such as marine functional zoning, main function zoning, integrated coastal zone management, to ensure the sustainable utilization of the coastal zone and promote the development of coastal economic. However, in practice, the effect is not satisfactory. This paper analyses the coastal areas of coastal zone management on coastal economic growth contribution based on coastal areas economic development data with the 2007-2015 in China, which uses the method of the evaluation index system of coastal zone management institutional efficiency. The results show that the coastal zone management institutional objectives are not clear, and the institutional has high repeatability. At the same time, over management of coastal zone leads to low economic efficiency because the government management boundary is blurred. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=institutional%20overlap" title="institutional overlap">institutional overlap</a>, <a href="https://publications.waset.org/abstracts/search?q=over%20management" title=" over management"> over management</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20zone%20management" title=" coastal zone management"> coastal zone management</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20zone%20economy" title=" coastal zone economy"> coastal zone economy</a> </p> <a href="https://publications.waset.org/abstracts/74771/institutional-superposition-over-management-and-coastal-economic-development-coastal-areas-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74771.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">393</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">274</span> Seismic Response Analysis of Frame Structures Based on Super Joint Element Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Xu">Li Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Hong"> Yang Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Zhao%20Wen"> T.

However, rigid joint assumption has been generally used in the seismic response analysis of RC frames, in which two kinds of inelastic deformation of joint have been ignored. Based on OpenSees platform, ‘Super Joint Element Model’ with more detailed inelastic mechanism is used to simulate the inelastic response of joints. Two finite element models of typical RC plane frame, namely considering or ignoring the inelastic deformation of joint respectively, were established and analyzed under seven strong earthquake waves. The simulated global and local inelastic deformations of the RC plane frame is shown and discussed. The analyses also confirm the security of the earthquake-resistant frame designed according to Chinese codes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frame%20structure" title="frame structure">frame structure</a>, <a href="https://publications.waset.org/abstracts/search?q=beam-column%20joint" title=" beam-column joint"> beam-column joint</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20bar%20slippage" title=" longitudinal bar slippage"> longitudinal bar slippage</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20deformation" title=" shear deformation"> shear deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analysis" title=" nonlinear analysis"> nonlinear analysis</a> </p> <a href="https://publications.waset.org/abstracts/70780/seismic-response-analysis-of-frame-structures-based-on-super-joint-element-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70780.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">409</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">273</span> Study of the Behavior of Geogrid Mechanically Stabilized Earth Walls Under Cyclic Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongzhe%20Zhao">Yongzhe Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Liu"> Ying Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Liu"> Zhiyong Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20You"> Hui You</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The soil behind retaining wall is normally subjected to cyclic loading, for example traffic loading. Geotextile has been widely used to reinforce the soil for the purpose of reducing the settlement of the soil. A series of physical model tests were performed to investigate the settlement of footing under cyclic loading. The settlement of the footing, ground deformation and the vertical earth pressure in subsoil were presented and discussed under different types of geotextiles. The results indicate that including geotextiles significantly decreases the footing settlement and the stiffer the geotextile, the less the settlement. Under cyclic loading, the soil below the footing shows dilation within certain depths and beyond that it experiences contraction. The location of footing relative to the retaining wall has important effects on the deformation behavior of the soil in the ground, and the closer the footing to the retaining wall, the greater the contraction soil shows. This is because the retaining wall experienced greater lateral displacement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20model%20tests" title="physical model tests">physical model tests</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20retaining%20wall" title=" reinforced retaining wall"> reinforced retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=footing" title=" footing"> footing</a> </p> <a href="https://publications.waset.org/abstracts/150601/study-of-the-behavior-of-geogrid-mechanically-stabilized-earth-walls-under-cyclic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150601.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">155</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">272</span> The Application of the Analytic Basis Function Expansion Triangular-z Nodal Method for Neutron Diffusion Calculation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunpeng%20Wang">Kunpeng Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongchun"> Hongchun</a>, <a href="https://publications.waset.org/abstracts/search?q=Wu"> Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Liangzhi%20Cao"> Liangzhi Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Chuanqi%20Zhao"> Chuanqi Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The distributions of homogeneous neutron flux within a node were expanded into a set of analytic basis functions which satisfy the diffusion equation at any point in a triangular-z node for each energy group, and nodes were coupled with each other with both the zero- and first-order partial neutron current moments across all the interfaces of the triangular prism at the same time. Based this method, a code TABFEN has been developed and applied to solve the neutron diffusion equation in a complicated geometry. In addition, after a series of numerical derivation, one can get the neutron adjoint diffusion equations in matrix form which is the same with the neutron diffusion equation; therefore, it can be solved by TABFEN, and the low-high scan strategy is adopted to improve the efficiency.

In this approach, IR serves as the pretreatment device before the sweat fingerprints was illuminated by blue light. An annular blue light source was adopted for visualizing latent sweat fingerprints. Sample fingerprints were examined under various conditions after deposition, and experimental results indicate that the recovery rate of the latent sweat fingerprints is in the range of 50%-100% without chemical treatments. A mechanism for the observed visibility is proposed based on transportation and re-impregnation of fluorescer in paper at the region of water. And further exploratory experimental results gave the full support to the visible mechanism. Therefore, such a method as IR-pretreated in detecting latent fingerprints may be better for examination in the case where biological information of samples is needed for consequent testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20science" title="forensic science">forensic science</a>, <a href="https://publications.waset.org/abstracts/search?q=visualization" title=" visualization"> visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20radiation" title=" infrared radiation"> infrared radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=blue%20light" title=" blue light"> blue light</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20sweat%20fingerprints" title=" latent sweat fingerprints"> latent sweat fingerprints</a>, <a href="https://publications.waset.org/abstracts/search?q=detection" title=" detection"> detection</a> </p> <a href="https://publications.waset.org/abstracts/80555/visualization-of-latent-sweat-fingerprints-deposit-on-paper-by-infrared-radiation-and-blue-light" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80555.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">497</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">270</span> Multi-Band Frequency Conversion Scheme with Multi-Phase Shift Based on Optical Frequency Comb</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tao%20Lin">Tao Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Shanghong%20Zhao"> Shanghong Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yufu%20Yin"> Yufu Yin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihang%20Zhu"> Zihang Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Jiang"> Wei Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuan%20Li"> Xuan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiurong%20Zheng"> Qiurong Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple operated, stable and compact multi-band frequency conversion and multi-phase shift is proposed to satisfy the demands of multi-band communication and radar phase array system. The dual polarization quadrature phase shift keying (DP-QPSK) modulator is employed to support the LO sideband and the optical frequency comb simultaneously. Meanwhile, the fiber is also used to introduce different phase shifts to different sidebands. The simulation result shows that by controlling the DC bias voltages and a C band microwave signal with frequency of 4.5 GHz can be simultaneously converted into other signals that cover from C band to K band with multiple phases. It also verifies that the multi-band and multi-phase frequency conversion system can be stably performed based on current manufacturing art and can well cope with the DC drifting. It should be noted that the phase shift of the converted signal also partly depends of the length of the optical fiber. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microwave%20photonics" title="microwave photonics">microwave photonics</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-band%20frequency%20conversion" title=" multi-band frequency conversion"> multi-band frequency conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-phase%20shift" title=" multi-phase shift"> multi-phase shift</a>, <a href="https://publications.waset.org/abstracts/search?q=conversion%20efficiency" title=" conversion efficiency"> conversion efficiency</a> </p> <a href="https://publications.waset.org/abstracts/96199/multi-band-frequency-conversion-scheme-with-multi-phase-shift-based-on-optical-frequency-comb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96199.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">269</span> Deep Reinforcement Learning for Optimal Decision-Making in Supply Chains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nitin%20Singh">Nitin Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Meng%20Ling"> Meng Ling</a>, <a href="https://publications.waset.org/abstracts/search?q=Talha%20Ahmed"> Talha Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Tianxia%20Zhao"> Tianxia Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinier%20van%20de%20Pol"> Reinier van de Pol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose the use of reinforcement learning (RL) as a viable alternative for optimizing supply chain management, particularly in scenarios with stochasticity in product demands. RL’s adaptability to changing conditions and its demonstrated success in diverse fields of sequential decision-making makes it a promising candidate for addressing supply chain problems. We investigate the impact of demand fluctuations in a multi-product supply chain system and develop RL agents with learned generalizable policies. We provide experimentation details for training RL agents and statistical analysis of the results. We study the generalization ability of RL agents for different demand uncertainty scenarios and observe superior performance compared to the agents trained with fixed demand curves.

The membrane separation technologies, which is no phase change, without pharmaceutical dosing, reprocessing costs low, less energy consumption, etc., have been widely applied in oily wastewater treatment. In our lab, a kind of low cost ceramic microfiltration membranes with a separation layer of attapulgite nanofibers (attapulgite nanofiber-like microfiltration membranes) has been prepared and applied in the purification of cellulase fermentation broth and TiO2 nanoparticles system successfully. In this paper, this new attapulgite nanofiber-like microfiltration membrane was selected to try to separate water from oily wastewater. The oil-in water emulsion was obtained from mixing 1 g/L engine oil, 0.5 g/L Tween-80, 0.5 g/L Span-80 and distilled water at mild speed in blender for 2 min. The particle size distribution of the oil-in-water emulsion was controlled. The maximum steady flux and COD rejection for a 0.2 um attapulgite nanofiber-like microfiltration membrane can reach about 450 L. m-2. h-1 and 98% at 0.2 MPa.

Then, the infrared spectral data, atomic charge and molecular orbitals of acrylamide as well as solvation effect of polyacrylamide are calculated to predict their physicochemical performance.

The brain-machine interface (BCI) of the neural prosthesis records signals from neurons and uses mathematical modeling to decode them, converting desired movements into body movements. In order to improve the patient's neural control, the prosthesis is given a natural feeling. It records data from sensitive areas from the body to the prosthetic limb and encodes signals in the form of electrical stimulation to the brain. In our research, the brain-computer interface (BCI) is a bridge connecting patients’ cognition and the real world, allowing information to interact with each other. The efficient work between the two is achieved through external devices. The flow of information is controlled by BCI’s ability to record neuronal signals and decode signals, which are converted into device control. In this way, we could encode information and then send it to the brain through electrical stimulation, which has significant medical application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomedical%20engineering" title="biomedical engineering">biomedical engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=brain-computer%20interface" title=" brain-computer interface"> brain-computer interface</a>, <a href="https://publications.waset.org/abstracts/search?q=prosthesis" title=" prosthesis"> prosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20control" title=" neural control"> neural control</a> </p> <a href="https://publications.waset.org/abstracts/138055/mechanical-prosthesis-controlled-by-brain-computer-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138055.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">181</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">263</span> Ultimate Stress of the Steel Tube in Circular Concrete-Filled Steel Tube Stub Columns Subjected to Axial Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siqi%20Lin">Siqi Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yangang%20Zhao"> Yangang Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete-filled steel tube column achieves the excellent performance of high strength, stiffness, and ductility due to the confinement from the steel tube.

Experimental results show that the series connection pattern has much better performance in natural impact or shock absorption, which indicate promising applications in robots’ safe and physical interaction with humans and objects in various environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impedance%20control" title="impedance control">impedance control</a>, <a href="https://publications.waset.org/abstracts/search?q=Maxwell%20model" title=" Maxwell model"> Maxwell model</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20control" title=" force control"> force control</a>, <a href="https://publications.waset.org/abstracts/search?q=dexterous%20manipulation" title=" dexterous manipulation"> dexterous manipulation</a> </p> <a href="https://publications.waset.org/abstracts/79604/stability-analysis-and-experimental-evaluation-on-maxwell-model-of-impedance-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79604.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">497</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">256</span> Validation of the Career Motivation Scale among Chinese University and Vocational College Teachers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wei%20Zhang">Wei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lifen%20Zhao"> Lifen Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study aims to translate and validate the Career Motivation Scale among Chinese university and vocational college teachers. Exploratory factor analysis supported a three-factor structure that was consistent with the original structure of career motivation: career insight, career identity, and career resilience. Confirmatory factor analysis showed that a second-order three-factor model with correlated measurement errors best fit the data. Configural, metric, and scalar invariance models were tested, demonstrating that the Chinese version of the Career Motivation Scale did not differ across groups of school type, educational level, and working years in current institutions. The concurrent validity of the Chinese Career Motivation Scale was confirmed by its significant correlations with work engagement, career adaptability, career satisfaction, job crafting, and intention to quit. The results of the study indicated that the Chinese Career Motivation Scale was a valid and reliable measure of career motivation among university and vocational college teachers in China. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=career%20motivation%20scale" title="career motivation scale">career motivation scale</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20University" title=" Chinese University"> Chinese University</a>, <a href="https://publications.waset.org/abstracts/search?q=vocational%20college%20teachers" title=" vocational college teachers"> vocational college teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20invariance" title=" measurement invariance"> measurement invariance</a>, <a href="https://publications.waset.org/abstracts/search?q=validation" title=" validation"> validation</a> </p> <a href="https://publications.waset.org/abstracts/150635/validation-of-the-career-motivation-scale-among-chinese-university-and-vocational-college-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150635.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">132</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">255</span> The Pedagogical Functions of Arts and Cultural-Heritage Education with ICTs in Museums – A Case Study of FINNA and Google Art </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pei%20Zhao">Pei Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Sintonen"> Sara Sintonen</a>, <a href="https://publications.waset.org/abstracts/search?q=Heikki%20Kyn%C3%A4slahti"> Heikki Kynäslahti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital museums and arts galleries have become popular in museum education and management. Museum and arts galleries website is one of the most effective and efficient ways. Google, a corporation specializing in Internet-related services and projects, not only puts high-resolution arts images online, but also uses augmented-reality in digital art gallery. The Google Art Project, Google’s production, provides users a platform in appreciating and learning arts. After Google Art Project, more and more countries released their own museum and arts gallery websites, like British Paining in BBC, and FINNA in Finland. Pedagogical function in these websites is one of the most important functions. In this paper, we use Google Art Project and FINNA as the case studies to investigate what kinds of pedagogical functions exist in these websites.

The CO<sub>2</sub> emissions of public passenger transport in Tianjin from 1995 to 2010 are estimated with IPCC CO<sub>2</sub> counting method, which shows that the total CO<sub>2</sub> emissions of Tianjin public passenger transport have gradually become stable at 1,425.1 thousand tons. And then the CO<sub>2</sub> emissions of the buses, taxies, and rail transits are calculated respectively. A CO<sub>2</sub> emission of 829.9 thousand tons makes taxies become the largest CO<sub>2</sub> emissions source among the public passenger transport in Tianjin. Combining with passenger volume, this paper analyzes the CO<sub>2</sub> emissions proportion of the buses, taxies, and rail transits compare the passenger transport rate with the proportion of CO<sub>2</sub> emissions, as well as the CO<sub>2</sub> emissions change of per 10,000 people. The passenger volume proportion of bus among the three public means of transport is 72.62% which is much higher than its CO<sub>2</sub> emissions proportion of 36.01%, with the minimum number of CO<sub>2</sub> emissions per 10,000 people of 4.90 tons. The countermeasures to reduce CO<sub>2</sub> emissions of public passenger transport in Tianjin are to develop rail transit, update vehicles and use alternative fuel vehicles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20passenger%20transport" title="public passenger transport">public passenger transport</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20emissions" title=" carbon emissions"> carbon emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=countermeasures" title=" countermeasures"> countermeasures</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a> </p> <a href="https://publications.waset.org/abstracts/26131/analysis-of-the-co2-emissions-of-public-passenger-transport-in-tianjin-city-of-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26131.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">429</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">253</span> Dynamics of Adiabatic Rapid Passage in an Open Rabi Dimer Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Justin%20Zhengjie%20Tan">Justin Zhengjie Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Zhao"> Yang Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Adiabatic Rapid Passage, a popular method of achieving population inversion, is studied in a Rabi dimer model in the presence of noise which acts as a dissipative environment. The integration of the multi-Davydov D2 Ansatz into the time-dependent variational framework enables us to model the intricate quantum system accurately. By influencing the system with a driving field strength resonant with the energy spacing, the probability of adiabatic rapid passage, which is modelled after the Landau Zener model, can be derived along with several other observables, such as the photon population. The effects of a dissipative environment can be reproduced by coupling the system to a common phonon mode. By manipulating the strength and frequency of the driving field, along with the coupling strength of the phonon mode to the qubits, we are able to control the qubits and photon dynamics and subsequently increase the probability of Adiabatic Rapid Passage happening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum%20electrodynamics" title="quantum electrodynamics">quantum electrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=adiabatic%20rapid%20passage" title=" adiabatic rapid passage"> adiabatic rapid passage</a>, <a href="https://publications.waset.org/abstracts/search?q=Landau-Zener%20transitions" title=" Landau-Zener transitions"> Landau-Zener transitions</a>, <a href="https://publications.waset.org/abstracts/search?q=dissipative%20environment" title=" dissipative environment"> dissipative environment</a> </p> <a href="https://publications.waset.org/abstracts/167520/dynamics-of-adiabatic-rapid-passage-in-an-open-rabi-dimer-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167520.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">252</span> A Simple Approach for the Analysis of First Vibration Mode of Layered Soil Profiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haizhong%20Zhang">Haizhong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan-Gang%20Zhao"> Yan-Gang Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fundamental period, mode shape, and participation factor are important basic information for the understanding of earthquake response of ground.

Both experimental and numerical investigations are conducted to study the mechanism of pulse combustion and its potential application in fabric drying. To gain insight on flame-acoustic dynamic interaction and pulsating flow characteristics, 3D numerical simulation of the pulse combustion process of a premixed turbulent flame in a Rijke-type combustor is performed. Two parameters are examined: (1) fuel-air ratio, (2) inlet flow velocity. Their effects on triggering pulsating flow and Nusselt number are studied. As each of the parameters is varied, Nusselt number characterizing the heat transfer rate and the heat-driven pulsating flow signature is found to change. The main nonlinearity is identified in the heat fluxes. To validate our numerical findings, a cylindrical T-shaped Rijke-type combustor made of quartz-glass with a Bunsen burner is designed and tested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulse%20combustion" title="pulse combustion">pulse combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=fabric%20drying" title=" fabric drying"> fabric drying</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20oscillations" title=" combustion oscillations"> combustion oscillations</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20oscillations" title=" pressure oscillations"> pressure oscillations</a> </p> <a href="https://publications.waset.org/abstracts/43423/numerical-and-experimental-investigation-of-pulse-combustion-for-fabric-drying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43423.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">241</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">247</span> The Study on Life of Valves Evaluation Based on Tests Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Binjuan%20Xu">Binjuan Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Qian%20Zhao"> Qian Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ping%20Jiang"> Ping Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Guo"> Bo Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhijun%20Cheng"> Zhijun Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoyue%20Wu"> Xiaoyue Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Astronautical valves are key units in engine systems of astronautical products; their reliability will influence results of rocket or missile launching, even lead to damage to staff and devices on the ground.

There are quite a few literature doing research based on few failure test data to estimate valves’ reliability, thus this paper proposed a new method to estimate valves’ reliability, according to the corresponding tests of different failure modes, this paper takes advantage of tests data which acquired from temperature, vibration, and action tests to estimate reliability in every failure modes, then this paper has regarded these three kinds of tests as three stages in products’ process to integrate these results to acquire valves’ reliability. Through the comparison of results achieving from tests data and simulated data, the results have illustrated how to obtain valves’ reliability based on the few failure data with failure modes and prove that the results are effective and rational. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=censored%20data" title="censored data">censored data</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20tests" title=" temperature tests"> temperature tests</a>, <a href="https://publications.waset.org/abstracts/search?q=valves" title=" valves"> valves</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20tests" title=" vibration tests"> vibration tests</a> </p> <a href="https://publications.waset.org/abstracts/84900/the-study-on-life-of-valves-evaluation-based-on-tests-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84900.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">345</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">246</span> Applying Massively Parallel Sequencing to Forensic Soil Bacterial Profiling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hui%20Li">Hui Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Xueying%20Zhao"> Xueying Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ke%20Ma"> Ke Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Cao"> Yu Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Fan%20Yang"> Fan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingwen%20Xu"> Qingwen Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenbin%20Liu"> Wenbin Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil can often link a person or item to a crime scene, which makes it a valuable evidence in forensic casework. Several techniques have been utilized in forensic soil discrimination in previous studies. Because soil contains a vast number of microbiomes, the analyse of soil microbiomes is expected to be a potential way to characterise soil evidence. In this study, we applied massively parallel sequencing (MPS) to soil bacterial profiling on the Ion Torrent Personal Genome Machine (PGM). Soils from different regions were collected repeatedly. V-region 3 and 4 of Bacterial 16S rRNA gene were detected by MPS. Operational taxonomic units (OTU, 97%) were used to analyse soil bacteria. Several bioinformatics methods (PCoA, NMDS, Metastats, LEfse, and Heatmap) were applied in bacterial profiles. Our results demonstrate that MPS can provide a more detailed picture of the soil microbiomes and the composition of soil bacterial components from different region was individualistic. In conclusion, the utility of soil bacterial profiling via MPS of the 16S rRNA gene has potential value in characterising soil evidences and associating them with their place of origin, which can play an important role in forensic science in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20profiling" title="bacterial
