Abstract: 本文介绍图像超分辨的重建技术及其应用,图像超分辨技术的过程即获得比单幅图像更多的额外信息,然后通过特定的算法,把这些额外的信息融入到原来的图像当中,获得一幅高质量、高清晰度的图像。图像超分辨率重建技术可以分为基于重建的超分辨率重建技术和基于学习的超分辨率重建技术。基于重建的超分辨重建技术主要是依据退化模型,通过不同的算法来估计高分辨率图像。而基于学习的超分辨率重建技术则是从训练样本中获得先验信息,对原始低分辨率图像进行补充。本文详细介绍了基于重建和基于学习的超分辨重建技术的一些主要算法。随着人们对数字图像的分辨率要求越来越高,图像超分辨技术应用逐渐广泛,涉及军事、医学、银行、勘探等很多领域。
Image super-resolution reconstruction technique and its application are introduced in this paper. Image super resolution technology process is to obtain more additional information than single image, and then with specific algorithm, the additional information is put into the original image to obtain an image with high quality and high definition. Super-resolution reconstruction includes two kinds of technology: reconstruction-based technology and learning-based technology. The reconstruction-based technology is estimating a high-resolution image from inputting images according to specific degradation model. Learning-based technology is supplying inputting images with prior knowledge from training examples. This paper introduces some major algorithms of reconstruction-based technology and learning-based technology in detail. As people are getting higher and higher requirement for the resolution of the digital image, image super resolution technology is applied more widely in many fields, such as military, medicine, bank, exploration, etc.

计算机系统应用 , 2010,
Abstract: Pervasive computing environment is a highly dynamic distributed environment in which principals collaborate spontaneously and unpredictably. Therefore, the pervasive computing puts more emphasis on the role of trust and puts forward higher request to system security than traditional calculation. A new dynamic collaborative trust model composed trust-reputation module and risk module was proposed based on combining credence elements and information safety risk assessment. This model resolve the limitations in the integrality of evidence used for the trust judgment, and in favor of setting up the reliable trust relationship in the entities, and improving environment and information security of universal.

Abstract: 针对分布式驱动电动汽车各车轮电机力矩和液压制动力矩可独立控制的特点,以操纵稳定性为目标,设计电机与液压制动复合分配的控制策略.控制策略采用分层控制的结构,上层运动控制器根据驾驶员输入和车辆状态的反馈求取广义力,下层控制分配器在执行器约束及速度约束下,考虑轮胎纵侧耦合特性对横摆转矩的影响,采用二次规划法进行转矩分配,实现车辆的稳定性控制效果.最后利用CARSIM和MATLAB软件对电液复合算法进行了联合仿真,并进行了实车试验来验证算法,最终的仿真和试验结果表明复合分配控制策略的控制效果相对仅用电机控制时要好,提高了车辆的稳定性控制效果.
Based on the characteristic of distributed drive electric vehicles that the torque of motors and hydraulic brake system can be controlled, an algorithm combing motors and hydraulic system was proposed with the aim of stability control. The algorithm used a hierarchical control structure. The upper layer calculates the generalized force based on the driver input and vehicle state. Under the constraint of actuators and speed and the influence of tire coupling characteristic, the lower layer takes quadratic programming method to optimize torque allocation. Finally the algorithm was simulated on CARSIM and MATLAB platform and verified by vehicle tests. The results of simulations and tests show that the algorithm can improve the stability. And the control result of the algorithm of motors and hydraulic brake system is better than that of motors

Abstract: 随着计算科学的发展,研究人员为探索流固耦合问题的物理机理而提出了众多的数值方法。其中,耦合的移动粒子半隐式方法MPS(Moving Particle Semi-Implicit method)和有限单元法FEM(Finite Element method)为流固耦合问题的数值仿真工作提供了新的途径。本文所有流场的数值模拟工作均采用课题组自主开发的网格法求解器MLParticle-SJTU来完成。该求解器在原始的MPS法基础上,对核函数、压力梯度模型、压力泊松方程的求解和自由面判断方式等方面进行了改进。此外,在该求解器框架内,基于FEM法拓展了针对结构场进行求解的功能。首先,对MPS和FEM方法的理论模型及其耦合策略进行了介绍。然后,采用该自研MPS-FEM耦合求解器,数值模拟了溃坝流动对弹性结构的冲击及其相互作用的标准问题。通过将结构变形及自由面波型变化等结果与已发表结果进行对比,验证了该求解器在处理带自由面剧烈变化的粘性流体和柔性变形结构的耦合作用问题上的可行性。
With the development of computational science,various kinds of numerical methods are proposed for the analysis of fluid-structure interaction problems.Recently,a coupled Moving Particle Semi-implicit(MPS) method and Finite Element Method(FEM) is developed as a new approach for FSI problems.In the present study,simulation of fluid fields is carried out by the mesh-free method solver MLParticle-SJTU.The solver is implemented based on the MPS method with improvements on the kernel function,free surface detection,gradient model and Possion’s equation of pressure.Furthermore,the module for calculation of structural deformation is developed base on the FEM in the framework of MLParticle-SJTU.In this paper,both MPS and FEM are introduced firstly.Then,the benchmark of the interact between the dam-break flow and the elastic structure is numerically investigated with the help of the presented MPS-FEM coupled solver.Deformation of the elastic structure and evolution of the violent free surface are found to be in good agreement with published results,which shows that the proposed MPS-FEM coupled method is capable of dealing with structural deformation interacting with violent free surface flow.
