The paper investigates the issue of damage in interfacial materials using M-integral. It demonstrates that integration path M-integral can cross material interface. numerical calculation is realized by domain integral method. accuracy model was verified analytical solutions. factors affecting are explored with help finite elements. study explores effects elastic modulus ratio, defects, and load on M-integral, proposes an equivalent calibration method based results suggest once ratio exceeds...
Vertical deformation estimation can be a significant tool in preventing geological hazards and managing environment impacts of underground mining. Common ground surface vertical calculations are challenged by difficult data collection dependence on prior knowledge. SVD (singular value decomposition) method was applied to estimate from single pair SAR (synthetic aperture radar) mining region. During the study, LOS (line sight) azimuth displacement obtained using two pass D-InSAR (differential...
Synthetic Aperture Radar (SAR) images are commonly used to monitor glacier flow velocity at Greenland Ice Sheet (GrIS). However, offset-tracking with SAR imagery in summer usually show poor quality because the rapid ice surface freezing-melting cycles contaminating backscattering characteristic, while optical less sensitive this phenomenon. In study, we combine Sentinel-1 and -2 create time series for Petermann glacier, located northern GrIS. Firstly, technique is employed acquire initial...
Social welfare and profit are two main factors to be included in the operational goal of bus services. It is assumed that conventional services “welfare pro” with more consideration social welfare, while customized “profit profit, each service maximize overall payoffs, namely, weighted sum profit. A bi-level pricing game proposed shed light on impact services’ competition payoffs when objectives different weights adopted. case study shows strategies have a significant The operator should...
格陵兰冰盖流速监测对定量估算冰盖物质损失以及研究冰盖对全球变暖的响应具有重要意义。利用SAR影像强度信息进行偏移量追踪是目前冰川流速监测的主要方法。冰川表面散射特性的变化会导致SAR影像强度信息发生改变,导致影像匹配失相关,从而造成提取的流速场中存在大量错误与空洞。为了克服该问题,本文提出了一套基于Sentinel-1...
Price discrimination is widely employed to regulate on-street parking behaviors provide better service users, and the prices are usually set according occupancy of spaces without direct consideration user perception. A binary logit-style choice model built describe between off-street parking. new index, named price elasticity expected perceived cost, proposed evaluate users’ response charge. Based on theory second-degree discrimination, three types defined duration, namely, preferred neutral...
The epoxy resin is an important part of superconducting devices, and nanoparticles can improve the properties at low temperature. However, performance epoxy/nanoparticles composites temperature still unclear. In this work, pure three epoxy-polyhedral oligomeric silsesquioxanes (POSS) models are proposed. results molecular dynamics (MD) simulation show that POSS mechanical (bulk modulus, Young's modulus shear modulus) As for mean square radius gyration displacement, different organic groups...
Epoxy resin is an important part for superconducting devices, adding nanoparticles into epoxy effective way to improve the electrical properties. However, mechanical properties of at low temperature not clear. In this paper, pure and epoxy-polyhedral oligomeric silsesquioxanes (POSS) models are proposed. Then molecular dynamics simulation was used analyze Our results show that POSS can temperature. The bulk modulus decreases with increasing temperature, effect particles varies when changes.
