the development of artificial intelligence (AI), deep learning (DL) has been extensively applied in Android apps. Compared with traditional Android apps (traditional apps), deep learning based Android apps (DL-based apps) need to use more third-party application programming interfaces (APIs) to complete complex DL inference tasks. However, existing methods (e.g., FlowDroid) for detecting sensitive information leakage in Android apps cannot be directly used to detect DL-based apps as they are difficult to detect third-party APIs. To solve this problem, we design DLtrace; a new static information flow analysis tool that can effectively recognize third-party APIs. With our proposed trace and detection algorithms, DLtrace can also efficiently detect privacy leaks caused by sensitive APIs in DL-based apps. Moreover, using DLtrace, we summarize the non-sequential characteristics of DL inference tasks in DL-based apps and the specific functionalities provided by DL models for such apps. We propose two formal definitions to deal with the common polymorphism and anonymous inner-class problems in the Android static analyzer. We conducted an empirical assessment with DLtrace on 208 popular DL-based apps in the wild and found that 26.0% of the apps suffered from sensitive information leakage. Furthermore, DLtrace has a more robust performance than FlowDroid in detecting and identifying third-party APIs. The experimental results demonstrate that DLtrace expands FlowDroid in understanding DL-based apps and detecting security issues therein. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20computing" title="mobile computing">mobile computing</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning%20apps" title=" deep learning apps"> deep learning apps</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitive%20information" title=" sensitive information"> sensitive information</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20analysis" title=" static analysis"> static analysis</a> </p> <a href="https://publications.waset.org/abstracts/152909/dltrace-toward-understanding-and-testing-deep-learning-information-flow-in-deep-learning-based-android-apps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152909.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">178</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">993</span> Identifying Dominant Anaerobic Microorganisms for Degradation of Benzene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jian%20Peng">Jian Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenhui%20Xiong"> Wenhui Xiong</a>, <a href="https://publications.waset.org/abstracts/search?q=Zheng%20Lu"> Zheng Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An optimal recipe of amendment (nutrients and electron acceptors) was developed and dominant indigenous benzene-degrading microorganisms were characterized in this study. Lessons were learnt from the development of the optimal amendment recipe: (1) salinity and substantial initial concentration of benzene were detrimental for benzene biodegradation; (2) large dose of amendments can shorten the lag time for benzene biodegradation occurrence; (3) toluene was an essential co-substance for promoting benzene degradation activity. The stable isotope probing study identified incorporation 13C from 13C-benzene into microorganisms, which can be considered as a direct evidence of the occurrence of benzene biodegradation. The dominant mechanism for benzene removal was identified by quantitative polymerase chain reaction analysis to be nitrate reduction. Microbial analyses (denaturing gradient gel electrophoresis and 16S ribosomal RNA) demonstrated that members of genus Dokdonella spp., Pusillimonas spp., and Advenella spp. were predominant within the microbial community and involved in the anaerobic benzene bioremediation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benzene" title="benzene">benzene</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20anaerobic%20bioremediation" title=" enhanced anaerobic bioremediation"> enhanced anaerobic bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=stable%20isotope%20probing" title=" stable isotope probing"> stable isotope probing</a>, <a href="https://publications.waset.org/abstracts/search?q=biosep%20biotrap" title=" biosep biotrap"> biosep biotrap</a> </p> <a href="https://publications.waset.org/abstracts/50612/identifying-dominant-anaerobic-microorganisms-for-degradation-of-benzene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50612.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">341</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">992</span> Study on Science and Technology Resources Coordinated Development and Innovation of Beijing-Tianjin-Hebei Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hong%20Zhang">Hong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Runlian%20Miao"> Runlian Miao</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Zhang"> Min Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coordinated development of Beijing-Tianjin-Hebei region is of great importance and has been emphasized by the government in recent years. Beijing-Tianjin-Hebei region accumulates a large part of S&T resources of the whole country and boasts the most influential achievements. In order to improve innovation capability of the region, universities, research institutions and enterprises from Beijing, Tianjin and Hebei have cooperated in many forms, but technological innovation is not so satisfactory due to unbalanced allocation, poor sharing and low utilization efficiency of S&T resources. Therefore, it’s very necessary to promote resources sharing, optimize their overall layout, and enhance their innovation performance, which can further deepen coordination development of the region. This study focuses on S&T resources with the methods of documents research plus field investigation and qualitative research combing plus quantitive research. It starts from the macro background of promoting coordinated development of Beijing-Tianjin-Hebei region and arrives at improving regional innovation capability. Firstly, the author makes a literature review on coordinated development of Beijing-Tianjin-Hebei region and summarizes that coordinated development has been carried forward in the major fields which lay foundation for regional innovation; secondly, analyzes current S&T resources distribution and coordinated innovation by taking key industries as the examples; based on analysis of the status quo of resources sharing and innovation in the region, the author points out problems and obstacles that holdbacks coordinated innovation of the region and at last raises some suggestions to resources sharing and regional innovation. It reaches the conclusion that an efficient management mechanism, market laws, favorable environment, model innovation and incentive measures can help to accelerate resources sharing and regional innovation in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beijing-Tianjin-Hebei%20region" title="Beijing-Tianjin-Hebei region">Beijing-Tianjin-Hebei region</a>, <a href="https://publications.waset.org/abstracts/search?q=coordinated%20development" title=" coordinated development"> coordinated development</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=S%26T%20resources" title=" S&T resources"> S&T resources</a> </p> <a href="https://publications.waset.org/abstracts/89378/study-on-science-and-technology-resources-coordinated-development-and-innovation-of-beijing-tianjin-hebei-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89378.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">306</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">991</span> Patching and Stretching: Development of Policy Mixes for Entrepreneurship in China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jian%20Shao">Jian Shao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of entrepreneurship on economic, innovation, and employment has been widely acknowledged by scholars and governments. As an essential factor of influencing entrepreneurship activities, entrepreneurship policy creates a conducive environment to support and develop entrepreneurship. However, the challenge in developing entrepreneurship policy is that policy is normally a combination of many different goals and instruments. Instead of examining the effect of individual policy instruments, we argue that attention to a policy mix is necessary. In recent years, much attention has been focused on comparing a single policy instrument to a policy mix, evaluating the interactions between different instruments within a mix or assessment of particular policy mixes. However, another required step in understanding policy mixes is to understand how and why mixes evolve and change over time and to determine whether any changes are an improvement. In this paper, we try to trace the development of the policy mix for entrepreneurship in China by mapping the policy goals and instruments and reveal the process of policy mix changing over time. We find two main process mechanisms of the entrepreneurship policy mix in China: patching and stretching. Compared with policy repackaging, patching and stretching are more realistic processes in the real world of the policy mix, and they are possible to achieve effectiveness by avoiding conflicts and promoting synergies among policy goals and instruments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20design" title=" policy design"> policy design</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20mix" title=" policy mix"> policy mix</a>, <a href="https://publications.waset.org/abstracts/search?q=policy%20patching" title=" policy patching"> policy patching</a> </p> <a href="https://publications.waset.org/abstracts/128849/patching-and-stretching-development-of-policy-mixes-for-entrepreneurship-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128849.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">198</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">990</span> An Experimental Study of the Effectiveness of Lubricants in Reducing the Sidewall Friction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jian%20Zheng">Jian Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Li"> Li Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Maxime%20Daviault"> Maxime Daviault</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In several cases, one needs apply lubrication materials in laboratory tests to reduce the friction (shear strength) along the interfaces between a tested soil and the side walls of container. Several types of lubricants are available. Their effectiveness had been tested mostly through direct shear tests. These testing conditions are quite different than those when the tested soil is placed in the container. Thus, the shear strengths measured from direct shear tests may not be totally representative of those of interfaces between the tested soil and the sidewalls of container. In this paper, the effectiveness of different lubricants used to reduce the friction (shear strength) of soil-structure interfaces has been studied. Results show that the selected lubricants do not significantly reduce the sidewall friction (shear strength). Rather, the application of wax, graphite, grease or lubricant oil has effect to increase the sidewall shear strength due probably to the high viscosity of such materials. Subsequently, the application of lubricants between tested soil and sidewall and neglecting the friction (shear strength) along the sidewalls may lead to inaccurate test results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arching" title="arching">arching</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20tests" title=" laboratory tests"> laboratory tests</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricants" title=" lubricants"> lubricants</a> </p> <a href="https://publications.waset.org/abstracts/81128/an-experimental-study-of-the-effectiveness-of-lubricants-in-reducing-the-sidewall-friction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81128.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">281</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">989</span> Limiting Fracture Stress of Composite Ceramics with Symmetric Triangle Eutectic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jian%20Zheng">Jian Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinfeng%20Yu"> Jinfeng Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinhua%20Ni"> Xinhua Ni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The limiting fracture stress predicting model of composite ceramics with symmetric triangle eutectic was established based on its special microscopic structure. The symmetric triangle eutectic is consisted of matrix, the strong constraint inter-phase and reinforced fiber inclusions which are 120 degrees uniform symmetrical distribution. Considering the conditions of the rupture of the cohesive bond between matrix and fibers in eutectic and the stress concentration effect at the fiber end, the intrinsic fracture stress of eutectic was obtained. Based on the biggest micro-damage strain in eutectic, defining the load function, the macro-damage fracture stress of symmetric triangle eutectic was determined by boundary conditions. Introducing the conception of critical zone, the theoretical limiting fracture stress forecasting model of composite ceramics was got, and the stress was related to the fiber size and fiber volume fraction in eutectic.

Thus, it is essential to take into account spatial variations of hydrological processes in streamflow allocation at the watershed scale. This paper adapts the Distributed Large Basin Runoff Model (DLBRM) to the Heihe River Watershed, the second largest inland river with a drainage area of about 128,000 km2 in Northwest China, for understanding the transfer and partitioning mechanism among the glacier and snowmelt, surface runoff, evapotranspiration, and groundwater recharge among the upper, middle, and lower reaches in the study area. Results indicate that the upper reach Qilian Mountain area is the main source of streamflow for the middle reach agricultural oasis and downstream desert areas. Large withdrawals for agricultural irrigation in the middle reach had significantly depleted river flow for the lower reach desert ecosystems. Innovative conservation and enforcement programs need to be undertaken to ensure the successful implementation of water allocation plan of delivering 0.95 x 109 m3 of water downstream annually by the State Council in the Heihe River Watershed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DLBRM" title="DLBRM">DLBRM</a>, <a href="https://publications.waset.org/abstracts/search?q=Northwestern%20China" title=" Northwestern China"> Northwestern China</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20variation" title=" spatial variation"> spatial variation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20allocation" title=" water allocation"> water allocation</a> </p> <a href="https://publications.waset.org/abstracts/40864/application-of-hydrological-model-in-support-of-streamflow-allocation-in-arid-watersheds-in-northwestern-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40864.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">302</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">985</span> Numerical Investigation on the Interior Wind Noise of a Passenger Car</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liu%20Ying-jie">Liu Ying-jie</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%20Wen-bo"> Lu Wen-bo</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng%20Cheng-jian"> Peng Cheng-jian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the development of the automotive technology and electric vehicle, the contribution of the wind noise on the interior noise becomes the main source of noise. The main transfer path which the exterior excitation is transmitted through is the greenhouse panels and side windows. Simulating the wind noise transmitted into the vehicle accurately in the early development stage can be very challenging. The basic methodologies of this study were based on the Lighthill analogy; the exterior flow field around a passenger car was computed using unsteady Computational Fluid Dynamics (CFD) firstly and then a Finite Element Method (FEM) was used to compute the interior acoustic response. The major findings of this study include: 1) The Sound Pressure Level (SPL) response at driver’s ear locations is mainly induced by the turbulence pressure fluctuation; 2) Peaks were found over the full frequency range. It is found that the methodology used in this study could predict the interior wind noise induced by the exterior aerodynamic excitation in industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20noise" title="wind noise">wind noise</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=passenger%20car" title=" passenger car"> passenger car</a> </p> <a href="https://publications.waset.org/abstracts/108180/numerical-investigation-on-the-interior-wind-noise-of-a-passenger-car" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108180.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">171</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">984</span> Human-Centric Sensor Networks for Comfort and Productivity in Offices: Integrating Environmental, Body Area Network, and Participatory Sensing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chenlu%20Zhang">Chenlu Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wanni%20Zhang"> Wanni Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Florian%20Schaule"> Florian Schaule</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indoor environment in office buildings directly affects comfort, productivity, health, and well-being of building occupants. Wireless environmental sensor networks have been deployed in many modern offices to monitor and control the indoor environments. However, indoor environmental variables are not strong enough predictors of comfort and productivity levels of every occupant due to personal differences, both physiologically and psychologically. This study proposes human-centric sensor networks that integrate wireless environmental sensors, body area network sensors and participatory sensing technologies to collect data from both environment and human and support building operations. The sensor networks have been tested in one small-size and one medium-size office rooms with 22 participants for five months. Indoor environmental data (e.g., air temperature and relative humidity), physiological data (e.g., skin temperature and Galvani skin response), and physiological responses (e.g., comfort and self-reported productivity levels) were obtained from each participant and his/her workplace. The data results show that: (1) participants have different physiological and physiological responses in the same environmental conditions; (2) physiological variables are more effective predictors of comfort and productivity levels than environmental variables. These results indicate that the human-centric sensor networks can support human-centric building control and improve comfort and productivity in offices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20area%20network" title="body area network">body area network</a>, <a href="https://publications.waset.org/abstracts/search?q=comfort%20and%20productivity" title=" comfort and productivity"> comfort and productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=human-centric%20sensors" title=" human-centric sensors"> human-centric sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=participatory%20sensing" title=" participatory sensing"> participatory sensing</a> </p> <a href="https://publications.waset.org/abstracts/98570/human-centric-sensor-networks-for-comfort-and-productivity-in-offices-integrating-environmental-body-area-network-and-participatory-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98570.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">139</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">983</span> Characterization of Double Shockley Stacking Fault in 4H-SiC Epilayer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhe%20Li">Zhe Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Ju"> Tao Ju</a>, <a href="https://publications.waset.org/abstracts/search?q=Liguo%20Zhang"> Liguo Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zehong%20Zhang"> Zehong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Baoshun%20Zhang"> Baoshun Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In-grow stacking-faults (IGSFs) in 4H-SiC epilayers can cause increased leakage current and reduce the blocking voltage of 4H-SiC power devices. Double Shockley stacking fault (2SSF) is a common type of IGSF with double slips on the basal planes. In this study, a 2SSF in the 4H-SiC epilayer grown by chemical vaper deposition (CVD) is characterized. The nucleation site of the 2SSF is discussed, and a model for the 2SSF nucleation is proposed. Homo-epitaxial 4H-SiC is grown on a commercial 4 degrees off-cut substrate by a home-built hot-wall CVD. Defect-selected-etching (DSE) is conducted with melted KOH at 500 degrees Celsius for 1-2 min. Room temperature cathodoluminescence (CL) is conducted at a 20 kV acceleration voltage. Low-temperature photoluminescence (LTPL) is conducted at 3.6 K with the 325 nm He-Cd laser line. In the CL image, a triangular area with bright contrast is observed. Two partial dislocations (PDs) with a 20-degree angle in between show linear dark contrast on the edges of the IGSF. CL and LTPL spectrums are conducted to verify the IGSF’s type. The CL spectrum shows the maximum photoemission at 2.431 eV and negligible bandgap emission. In the LTPL spectrum, four phonon replicas are found at 2.468 eV, 2.438 eV, 2.420 eV and 2.410 eV, respectively. The Egx is estimated to be 2.512 eV. A shoulder with a red-shift to the main peak in CL, and a slight protrude at the same wavelength in LTPL are verified as the so called Egx- lines. Based on the CL and LTPL results, the IGSF is identified as a 2SSF. Back etching by neutral loop discharge and DSE are conducted to track the origin of the 2SSF, and the nucleation site is found to be a threading screw dislocation (TSD) in this sample. A nucleation mechanism model is proposed for the formation of the 2SSF. Steps introduced by the off-cut and the TSD on the surface are both suggested to be two C-Si bilayers height. The intersections of such two types of steps are along [11-20] direction from the TSD, while a four-bilayer step at each intersection. The nucleation of the 2SSF in the growth is proposed as follows. Firstly, the upper two bilayers of the four-bilayer step grow down and block the lower two at one intersection, and an IGSF is generated. Secondly, the step-flow grows over the IGSF successively, and forms an AC/ABCABC/BA/BC stacking sequence. Then a 2SSF is formed and extends by the step-flow growth. In conclusion, a triangular IGSF is characterized by CL approach. Base on the CL and LTPL spectrums, the estimated Egx is 2.512 eV and the IGSF is identified to be a 2SSF. By back etching, the 2SSF nucleation site is found to be a TSD. A model for the 2SSF nucleation from an intersection of off-cut- and TSD- introduced steps is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cathodoluminescence" title="cathodoluminescence">cathodoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=defect-selected-etching" title=" defect-selected-etching"> defect-selected-etching</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20Shockley%20stacking%20fault" title=" double Shockley stacking fault"> double Shockley stacking fault</a>, <a href="https://publications.waset.org/abstracts/search?q=low-temperature%20photoluminescence" title=" low-temperature photoluminescence"> low-temperature photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=nucleation%20model" title=" nucleation model"> nucleation model</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20carbide" title=" silicon carbide"> silicon carbide</a> </p> <a href="https://publications.waset.org/abstracts/51238/characterization-of-double-shockley-stacking-fault-in-4h-sic-epilayer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51238.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">316</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">982</span> Post Occupancy Evaluation of the Green Office Building with Different Air-Conditioning Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ziwei%20Huang">Ziwei Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Ge"> Jian Ge</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Shen"> Jie Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiantao%20Weng"> Jiantao Weng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Retrofitting of existing buildings plays a critical role to achieve sustainable development. This is being considered as one of the approaches to achieving sustainability in the built environment. In order to evaluate the different air-conditioning systems effectiveness and user satisfaction of the existing building which had transformed into green building effectively and accurately. This article takes the green office building in Zhejiang province, China as an example, analyzing the energy consumption, occupant satisfaction and indoor environment quality (IEQ) from the perspective of the thermal environment. This building is special because it combines ground source heat pump system and Variable Refrigerant Flow (VRF) air-conditioning system. Results showed that the ground source heat pump system(EUIa≈25.6) consumes more energy than VRF(EUIb≈23.8). In terms of a satisfaction survey, the use of the VRF air-conditioning was more satisfactory in temperature. However, the ground source heat pump is more satisfied in air quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post-occupancy%20evaluation" title="post-occupancy evaluation">post-occupancy evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20office%20building" title=" green office building"> green office building</a>, <a href="https://publications.waset.org/abstracts/search?q=air-conditioning%20systems" title=" air-conditioning systems"> air-conditioning systems</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20source%20heat%20pump%20system" title=" ground source heat pump system"> ground source heat pump system</a> </p> <a href="https://publications.waset.org/abstracts/88345/post-occupancy-evaluation-of-the-green-office-building-with-different-air-conditioning-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88345.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">196</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">981</span> Scene Classification Using Hierarchy Neural Network, Directed Acyclic Graph Structure, and Label Relations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Po-Jen%20Chen">Po-Jen Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian-Jiun%20Ding"> Jian-Jiun Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung-Wei%20Hsu"> Hung-Wei Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Yao%20Wang"> Chien-Yao Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jia-Ching%20Wang"> Jia-Ching Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A more accurate scene classification algorithm using label relations and the hierarchy neural network was developed in this work. In many classification algorithms, it is assumed that the labels are mutually exclusive. This assumption is true in some specific problems, however, for scene classification, the assumption is not reasonable. Because there are a variety of objects with a photo image, it is more practical to assign multiple labels for an image. In this paper, two label relations, which are exclusive relation and hierarchical relation, were adopted in the classification process to achieve more accurate multiple label classification results. Moreover, the hierarchy neural network (hierarchy NN) is applied to classify the image and the directed acyclic graph structure is used for predicting a more reasonable result which obey exclusive and hierarchical relations. Simulations show that, with these techniques, a much more accurate scene classification result can be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20network" title="convolutional neural network">convolutional neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=label%20relation" title=" label relation"> label relation</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchy%20neural%20network" title=" hierarchy neural network"> hierarchy neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=scene%20classification" title=" scene classification"> scene classification</a> </p> <a href="https://publications.waset.org/abstracts/66516/scene-classification-using-hierarchy-neural-network-directed-acyclic-graph-structure-and-label-relations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66516.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">458</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">980</span> The Richtmyer-Meshkov Instability Impacted by the Interface with Different Components Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sheng-Bo%20Zhang">Sheng-Bo Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huan-Hao%20Zhang"> Huan-Hao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhi-Hua%20Chen"> Zhi-Hua Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun%20Zheng"> Chun Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the Richtmyer-Meshkov instability has been studied numerically by using the high-resolution Roe scheme based on the two-dimensional unsteady Euler equation, which was caused by the interaction between shock wave and the helium circular light gas cylinder with different component distributions. The numerical results further discuss the deformation process of the gas cylinder, the wave structure of the flow field and quantitatively analyze the characteristic dimensions (length, height, and central axial width) of the gas cylinder, the volume compression ratio of the cylinder over time. In addition, the flow mechanism of shock-driven interface gas mixing is analyzed from multiple perspectives by combining it with the flow field pressure, velocity, circulation, and gas mixing rate. Then the effects of different initial component distribution conditions on interface instability are investigated. The results show when the diffusion interface transit to the sharp interface, the reflection coefficient gradually increases on both sides of the interface. When the incident shock wave interacts with the cylinder, the transmission of the shock wave will transit from conventional transmission to unconventional transmission. At the same time, the reflected shock wave is gradually strengthened, and the transmitted shock wave is gradually weakened, which leads to an increase in the Richtmyer-Meshkov instability. Moreover, the Atwood number on both sides of the interface also increases as the diffusion interface transit to the sharp interface, which leads to an increase in the Rayleigh-Taylor instability and the Kelvin-Helmholtz instability. Therefore, the increase in instability will lead to an increase the circulation, resulting in an increase in the growth rate of gas mixing rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shock%20wave" title="shock wave">shock wave</a>, <a href="https://publications.waset.org/abstracts/search?q=He%20light%20cylinder" title=" He light cylinder"> He light cylinder</a>, <a href="https://publications.waset.org/abstracts/search?q=Richtmyer-Meshkov%20instability" title=" Richtmyer-Meshkov instability"> Richtmyer-Meshkov instability</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20distribution" title=" Gaussian distribution"> Gaussian distribution</a> </p> <a href="https://publications.waset.org/abstracts/164153/the-richtmyer-meshkov-instability-impacted-by-the-interface-with-different-components-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164153.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">77</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">979</span> The Usefulness of Financial Certification in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Mei%20Wang">Chih-Mei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jon-Chao%20Hong"> Jon-Chao Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian-Hong%20Ye"> Jian-Hong Ye</a>, <a href="https://publications.waset.org/abstracts/search?q=Jing-Yun%20Fan"> Jing-Yun Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiao-Fei%20Lin"> Chiao-Fei Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The value of a certificate is to implement the criteria for evaluating work ability.

A total of 339 valid samples were subjected to confirmatory factor analysis and structural equation modeling; the results showed that the number of professional certificates was not significantly correlated with career promotion, but the number of professional certificates is negatively related to salary and benefits (S&B), while career promotion and S&B were positively related to job performance. The results show that the number of professional certificates does not play a significant role in the expectancy-value model.

Pd/TNAs was employed as an electrode in a photoelectrochemcial (PEC) system to simultaneously remove azo-dye and to generate hydrogen in the anodic and cathodic chamber, respectively. The chemical and physical properties of as-synthesized Pd/TNAs were characterized by scanning electron microscopy (SEM), ultraviolet–visible spectroscopy (UV-vis), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). SEM image indicates the diameter and the length of Pd/TNAs were approximately 300 nm and 2.5 μm, respectively. XPS analyses indicate that 1.13% (atomic %) of Pd was loaded onto the surface of TNAs. UV-vis results show that the band gap of TNAs was reduced from 3.2 eV to 2.37 eV after Pd loading. In addition, the electrochemical performances of Pd/TNAs were investigated by photocurrent density test and electrochemical impedance spectroscopy (EIS). The photocurrent (4.0 mA/cm²) of Pd /TNAs was higher than that of the uncoated TNAs (1.4 mA/cm²) at a bias potential of 1 V (vs. Ag/AgCl), indicating that Pd/TNAs-C can effectively separate photogenerated electrons and holes. The mechanism of our PEC system was proposed and discussed in detail in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pd%2FTNAs" title="Pd/TNAs">Pd/TNAs</a>, <a href="https://publications.waset.org/abstracts/search?q=photoelectrochemical" title=" photoelectrochemical"> photoelectrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=azo-dye%20degradation" title=" azo-dye degradation"> azo-dye degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20generation" title=" hydrogen generation "> hydrogen generation </a> </p> <a href="https://publications.waset.org/abstracts/80237/green-synthesized-palladium-loaded-titanium-nanotube-arrays-for-simultaneous-azo-dye-degradation-and-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80237.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">422</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">977</span> Evolution Mechanism of the Formation of Rock Heap under Seismic Action and Analysis on Engineering Geological Structure </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jian-Xiu%20Wan">Jian-Xiu Wan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yao%20Yin"> Yao Yin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In complex terrain and poor geological conditions areas, Railway, highway and other transportation constructions are still strongly developing. However, various geological disasters happened such as landslide, rock heap and so on. According to the results of geological investigation, the form of skirt (trapezoidal), semicircle and triangle rock heaps are mainly due to complex internal force and external force, in a certain extent, which is related to the terrain, the nature of the rock mass, the supply area and the surface shape of rock heap. Combined with the above factors, discrete element numerical simulation of rock mass is established under different terrain conditions based on 3DEC, and accelerated formation process of rock heap under seismic action is simulated. The fragmentation structure supply area is calculated, in which the most dangerous area is located. At the same time, the formation mechanism and development process are studied in different terrain conditions, and the structure of rock heap is judged by section, which can provide a strong theoretical and technical support for the prevention and control of geological disasters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3DEC" title="3DEC">3DEC</a>, <a href="https://publications.waset.org/abstracts/search?q=fragmentation%20structure" title=" fragmentation structure"> fragmentation structure</a>, <a href="https://publications.waset.org/abstracts/search?q=rock%20heap" title=" rock heap"> rock heap</a>, <a href="https://publications.waset.org/abstracts/search?q=slope" title=" slope"> slope</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20action" title=" seismic action"> seismic action</a> </p> <a href="https://publications.waset.org/abstracts/40697/evolution-mechanism-of-the-formation-of-rock-heap-under-seismic-action-and-analysis-on-engineering-geological-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40697.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">296</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">976</span> Evaluation of Green Infrastructure with Different Woody Plants Practice and Benefit Using the Stormwater Management-HYDRUS Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bei%20Zhang">Bei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhaoxin%20Zhang"> Zhaoxin Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lidong%20Zhao"> Lidong Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green infrastructures (GIs) for rainwater management can directly meet the multiple purposes of urban greening and non-point source pollution control. To reveal the overall layout law of GIs dominated by typical woody plants and their impact on urban environmental effects, we constructed a HYDRUS-1D and Stormwater management (SWMM) coupling model to simulate the response of typical root woody plant planting methods on urban hydrological. The results showed that the coupling model had high adaptability to the simulation of urban surface runoff control effect under different woody plant planting methods (NSE ≥0.64 and R² ≥ 0.71). The regulation effect on surface runoff showed that the average runoff reduction rate of GIs increased from 60 % to 71 % with the increase of planting area (5% to 25%) under the design rainfall event of the 2-year recurrence interval. Sophora japonica with tap roots was slightly higher than that of without plants (control) and Malus baccata (M. baccata) with fibrous roots. The comprehensive benefit evaluation system of rainwater utilization technology was constructed by using an analytic hierarchy process. The coupling model was used to evaluate the comprehensive benefits of woody plants with different planting areas in the study area in terms of environment, economy, and society. The comprehensive benefit value of planting 15% M. baccata was the highest, which was the first choice for the planting of woody plants in the study area. This study can provide a scientific basis for the decision-making of green facility layouts of woody plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20infrastructure" title="green infrastructure">green infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=comprehensive%20benefits" title=" comprehensive benefits"> comprehensive benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=runoff%20regulation" title=" runoff regulation"> runoff regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=woody%20plant%20layout" title=" woody plant layout"> woody plant layout</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling%20model" title=" coupling model"> coupling model</a> </p> <a href="https://publications.waset.org/abstracts/173239/evaluation-of-green-infrastructure-with-different-woody-plants-practice-and-benefit-using-the-stormwater-management-hydrus-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173239.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">69</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">975</span> The Use of Fractional Brownian Motion in the Generation of Bed Topography for Bodies of Water Coupled with the Lattice Boltzmann Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elysia%20Barker">Elysia Barker</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Guo%20Zhou"> Jian Guo Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ling%20Qian"> Ling Qian</a>, <a href="https://publications.waset.org/abstracts/search?q=Steve%20Decent"> Steve Decent</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A method of modelling topography used in the simulation of riverbeds is proposed in this paper, which removes the need for datapoints and measurements of physical terrain. While complex scans of the contours of a surface can be achieved with other methods, this requires specialised tools, which the proposed method overcomes by using fractional Brownian motion (FBM) as a basis to estimate the real surface within a 15% margin of error while attempting to optimise algorithmic efficiency. This removes the need for complex, expensive equipment and reduces resources spent modelling bed topography. This method also accounts for the change in topography over time due to erosion, sediment transport, and other external factors which could affect the topography of the ground by updating its parameters and generating a new bed. The lattice Boltzmann method (LBM) is used to simulate both stationary and steady flow cases in a side-by-side comparison over the generated bed topography using the proposed method and a test case taken from an external source. The method, if successful, will be incorporated into the current LBM program used in the testing phase, which will allow an automatic generation of topography for the given situation in future research, removing the need for bed data to be specified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bed%20topography" title="bed topography">bed topography</a>, <a href="https://publications.waset.org/abstracts/search?q=FBM" title=" FBM"> FBM</a>, <a href="https://publications.waset.org/abstracts/search?q=LBM" title=" LBM"> LBM</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20water" title=" shallow water"> shallow water</a>, <a href="https://publications.waset.org/abstracts/search?q=simulations" title=" simulations"> simulations</a> </p> <a href="https://publications.waset.org/abstracts/152925/the-use-of-fractional-brownian-motion-in-the-generation-of-bed-topography-for-bodies-of-water-coupled-with-the-lattice-boltzmann-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152925.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">98</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">974</span> Development of Solar Energy Resources for Land along the Transportation Infrastructure: Taking the Lan-Xin Railway in the Silk Road Economic Belt as an Example</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dan%20Han">Dan Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Yukun%20Zhang"> Yukun Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Zheng"> Jie Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20Zhang"> Rui Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Making full use of space along transportation infrastructure to develop renewable energy sources, especially solar energy resources, has become a research focus in relevant fields. In recent years, relevant international researches can be classified into three stages of theoretical and technical exploration, exploratory practice as well as planning implementation. Compared with traditional solar energy development mode, the development of solar energy resources in places along the transportation infrastructure has special advantages, which can also bring forth new opportunities for the development of green transportation. 'Road Integrated Photovoltaic', a development model of combining transport and new energy, has been actively studied and applied in developed countries, but it was still in its infancy in China. 'New Silk Road Economic Belt' has great advantage to carry out the 'Road Integrated Photovoltaic' because of the rich solar energy resources in its path, the shortages of renewable energy, the constraints of agricultural land and other reasons. Especially the massive amount of construction of transportation infrastructure brought by Silk Road Economic Belt, large area of developable land along the transportation line will be generated. Abundant solar energy recourses along the Silk Road will provide extremely superb practical opportunities to the land development along transportation infrastructure. We take PVsyst, GIS and Google map software for simulation of its potential by taking Lan-Xin Railway as an example, so potential electrical energy generation can be quantified and further analyzed. Research of 'New Silk Road Economic Belt' combined with 'Road Integrated Photovoltaic' is a creative development for the along transport and energy infrastructure. It not only can make full use of solar radiation and land in its path, but also bring more long-term advantages and benefits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=land%20use" title="land use">land use</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20road%20economic%20belt" title=" silk road economic belt"> silk road economic belt</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20infrastructure" title=" transportation infrastructure"> transportation infrastructure</a> </p> <a href="https://publications.waset.org/abstracts/81065/development-of-solar-energy-resources-for-land-along-the-transportation-infrastructure-taking-the-lan-xin-railway-in-the-silk-road-economic-belt-as-an-example" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81065.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">973</span> Flame Spread along Fuel Cylinders in High Pressures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanli%20Zhao">Yanli Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Chen"> Jian Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shouxiang%20Lu"> Shouxiang Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flame spread over solid fuels in high pressure situations such as nuclear containment shells and hyperbaric oxygen chamber has potential to result in catastrophic disaster, thus requiring best knowledge. This paper reveals experimentally the flame spread behaviors over fuel cylinders in high pressures. The fuel used in this study is polyethylene and polymethyl methacrylate cylinders with 4mm diameter. Ambient gas is fixed as air and total pressures are varied from naturally normal pressure (100kPa) to elevated pressure (400kPa). Flame appearance, burning rate and flame spread were investigated experimentally and theoretically. Results show that high pressure significantly affects the flame appearance, which is as the pressure increases, flame color changes from luminous yellow to orange and the orange part extends down towards the base of flame. Besides, the average flame width and height, and the burning rate are proved to increase with increasing pressure. What is more, flame spread rates become higher as pressure increases due to the enhancement of heat transfer from flame to solid surface in elevated pressure by performing a simplified heat balance analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cylinder%20fuel" title="cylinder fuel">cylinder fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20spread" title=" flame spread"> flame spread</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=high%20pressure" title=" high pressure"> high pressure</a> </p> <a href="https://publications.waset.org/abstracts/74731/flame-spread-along-fuel-cylinders-in-high-pressures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74731.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">378</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">972</span> Design and Development of a Lead-Free BiFeO₃-BaTiO₃ Quenched Ceramics for High Piezoelectric Strain Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Habib">Muhammad Habib</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Tang"> Lin Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Guoliang%20Xue"> Guoliang Xue</a>, <a href="https://publications.waset.org/abstracts/search?q=Attaur%20Rahman"> Attaur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Myong-Ho%20Kim"> Myong-Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Soonil%20Lee"> Soonil Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuefan%20Zhou"> Xuefan Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Zhang"> Yan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dou%20Zhang"> Dou Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Designing a high-performance, lead-free ceramic has become a cutting-edge research topic due to growing concerns about the toxic nature of lead-based materials. In this work, a convenient strategy of compositional design and domain engineering is applied to the lead-fee BiFeO₃-BaTiO₃ ceramics, which provides a flexible polarization-free-energy profile for domain switching. Here, simultaneously enhanced dynamic piezoelectric constant (d33* = 772 pm/V) and a good thermal-stability (d33* = 26% over the temperature of 20-180 ᵒC) are achieved with a high Curie temperature (TC) of 432 ᵒC. This high piezoelectric strain performance is collectively attributed to multiple effects such as thermal quenching, suppression of defect charges by donor doping, chemically induced local structure heterogeneity, and electric field-induced phase transition. Furthermore, the addition of BT content decreased octahedral tilting, reduced anisotropy for domain switching and increased tetragonality (cₜ/aₜ), providing a wider polar length for B-site cation displacement, leading to high piezoelectric strain performance. Atomic-resolution transmission electron microscopy and piezoelectric force microscopy combined with X-ray diffraction results strongly support the origin of high piezoelectricity. The high and temperature-stable piezoelectric strain response of this work is superior to those of other lead-free ceramics. The synergistic approach of composition design and the concept present here for the origin of high strain response provides a paradigm for the development of materials for high-temperature piezoelectric actuator applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piezoelectric" title="Piezoelectric">Piezoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=BiFeO3-BaTiO3" title=" BiFeO3-BaTiO3"> BiFeO3-BaTiO3</a>, <a href="https://publications.waset.org/abstracts/search?q=Quenching" title=" Quenching"> Quenching</a>, <a href="https://publications.waset.org/abstracts/search?q=Temperature-insensitive" title=" Temperature-insensitive"> Temperature-insensitive</a> </p> <a href="https://publications.waset.org/abstracts/173360/design-and-development-of-a-lead-free-bifeo3-batio3-quenched-ceramics-for-high-piezoelectric-strain-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173360.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">83</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">971</span> Improving Early Detection, Diagnosis And Intervention For Children With Autism Spectrum Disorder: A Cross-sectional Survey In China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yushen%20Dai">Yushen Dai</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Deng"> Tao Deng</a>, <a href="https://publications.waset.org/abstracts/search?q=Miaoying%20Chen"> Miaoying Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Baoqin%20Huang"> Baoqin Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Ji"> Yan Ji</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongshen%20Feng"> Yongshen Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaofei%20Liu"> Shaofei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongmei%20Zhong"> Dongmei Zhong</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Zhang"> Tao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lifeng%20Zhang"> Lifeng Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Detection and diagnosis are prerequisites for early interventions in the care of children with Autism Spectrum Disorder (ASD). However, few studies have focused on this topic. Aim: This study aims to characterize the timing from symptom detection to intervention in children with ASD and to identify the potential predictors of early detection, diagnosis, and intervention. Methods and procedures: A cross-sectional survey was conducted with 314 parents of children with ASD in Guangzhou, China. Outcomes and Results: This study found that most children (76.24%) were diagnosed within one year after detection, and 25.8% of them did not receive the intervention after diagnosis. Predictors to ASD diagnosis included ASD-related symptoms identified at a younger age, more serious symptoms, and initial symptoms with abnormal development and sensory anomalies. ASD-related symptoms observed at an older age, initial symptoms with the social deficit, sensory anomalies, and without language impairment, parents as the primary caregivers, family with lower income and less social support utilization increased the odds of the time lag between detection and diagnosis. Children whose fathers had a lower level of education were less likely to receive the intervention. Conclusions and Implications: The study described the time for detection, diagnosis, and interventions of children with ASD. Findings suggest that the ASD-related symptoms, the timing at which symptoms first become a concern, primary caregivers’ roles, father’s educational level, and the family economic status should be considered when offering support to improve early detection, diagnosis, and intervention. Helping children and their families take full advantage of support is also important. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title="autism spectrum disorder">autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=child" title=" child"> child</a>, <a href="https://publications.waset.org/abstracts/search?q=detection" title=" detection"> detection</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=intervention" title=" intervention"> intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20support" title=" social support"> social support</a> </p> <a href="https://publications.waset.org/abstracts/164336/improving-early-detection-diagnosis-and-intervention-for-children-with-autism-spectrum-disorder-a-cross-sectional-survey-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164336.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">90</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">970</span> Quantitative Assessment of Road Infrastructure Health Using High-Resolution Remote Sensing Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wang%20Zhaoming">Wang Zhaoming</a>, <a href="https://publications.waset.org/abstracts/search?q=Shao%20Shegang"> Shao Shegang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen%20Xiaorong"> Chen Xiaorong</a>, <a href="https://publications.waset.org/abstracts/search?q=Qi%20Yanan"> Qi Yanan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tian%20Lei"> Tian Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Jian"> Wang Jian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study conducts a comparative analysis of the spectral curves of asphalt pavements at various aging stages to improve road information extraction from high-resolution remote sensing imagery.

It is important to decrease the barge’s pitch motion and lay pipe in head sea in order to improve safety of the S-lay installation and dynamic positioning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=S-lay%20operation" title="S-lay operation">S-lay operation</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20positioning" title=" dynamic positioning"> dynamic positioning</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling%20motion" title=" coupling motion"> coupling motion</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20domain" title=" time domain"> time domain</a>, <a href="https://publications.waset.org/abstracts/search?q=allocation%20of%20thrust" title=" allocation of thrust "> allocation of thrust </a> </p> <a href="https://publications.waset.org/abstracts/8016/coupling-time-domain-analysis-for-dynamic-positioning-during-s-lay-installation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8016.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">465</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">968</span> Age and Population Structure of the Goby Parapocryptes Serperaster in the Mekong Delta, Vietnam, Based on Length-Frequency and Otolith Analyses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Quang%20Minh%20Dinh">Quang Minh Dinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Guang%20Qin"> Jian Guang Qin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabine%20Dittmann"> Sabine Dittmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinh%20Dac%20Tran"> Dinh Dac Tran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The age and population structure the dermal gopy Parapocryptes serperaster were studied using length distributions, otolith and von Bertalanffy model in the Mekong Delta over a whole year through monthly sampling. The sex ratio of P. serperaster was near 1:1, and von Bertalanffy growth parameters were L∞= 25.2 cm, K = 0.74 yr-1, and t0 = -0.22 yr-1. Fish size at first entry to fishery was 14.6 cm, and fishing mortality (1.57 yr-1) and natural mortality (1.51 yr-1) accounted for 51% and 49% of the total mortality (3.07 yr-1), respectively. Relative yield-per-recruit and biomass-per-recruit analyses revealed the levels of maximum exploitation yield (Emax = 0.83), maximum economic yield (E0.1 = 0.71) and the yield at 50% reduction of exploitation (E0.5 = 0.37). Otoliths from 164 female and 196 male gobies were readable, and the otolith morphometry data were used for age identification. The mean age estimated by reading otolith annual rings and by analysing length frequency distribution was consistent. This study shows that the otolith morphometry is a reliable method for aging this goby and possibly also applicable for other tropical gobies. The fishery analysis indicates that this goby stock has not been overexploited in the Mekong Delta. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parapcryptes%20serperaster" title="Parapcryptes serperaster">Parapcryptes serperaster</a>, <a href="https://publications.waset.org/abstracts/search?q=otolith" title=" otolith"> otolith</a>, <a href="https://publications.waset.org/abstracts/search?q=age" title=" age"> age</a>, <a href="https://publications.waset.org/abstracts/search?q=pulation%20structure" title=" pulation structure"> pulation structure</a>, <a href="https://publications.waset.org/abstracts/search?q=Vietnam" title=" Vietnam"> Vietnam</a> </p> <a href="https://publications.waset.org/abstracts/22313/age-and-population-structure-of-the-goby-parapocryptes-serperaster-in-the-mekong-delta-vietnam-based-on-length-frequency-and-otolith-analyses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22313.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">656</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">967</span> Subjective Well-being, Beliefs, and Lifestyles of First Year University Students in the UK</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaili%20C.%20Zhang">Kaili C.

Mathematical models are being proposed to study the dynamics of tree-grass coexistence and the stability of the systems. However, few of the models concentrates on spatial dynamics of the tree-grass coexistence. In this study, we modified an age-structured continuous-space population model for forests, obtaining an age-structured continuous-space population model for the tree-grass competition model. In the model, for thermal competitions, adult trees can out-compete grass, and grass can out-compete seedlings. We mathematically studied the model to make sure tree-grass coexistence solutions exist. Numerical experiments demonstrated that a fraction of area that trees or grass occupies can affect whether the coexistence is stable or not. We also tried regulating the mortality of adult trees with other parameters and the fraction of area trees and grass occupies were fixed; results show that the mortality of adult trees is also a factor affecting the stability of the tree-grass coexistence in this model. <p class="card-text"><strong>Keywords:</strong> <a
