In order to assist Boost converter design, the working process of the converter at discontinuous current mode was analyzed and a nonlinear mathematical model was estabilished as well. Case study on Matlab/ Simulink was performed with binary logical variable used, the simulation result was consistent with the theoretical analysis which proveed the validitd and feasibility of the proposed model. The model could be used to assist Boost circuit design effectively and supplie a basis for parameter optimization.

为了辅助升压变换器在应用中的设计，分析了电流断续状态下Boost变换器的工作过程，建立了这种状态下的Boost变换器非线性数学模型，在结合二进制逻辑变量，建立了Simulink模块下的变换器仿真模型，研究表明仿真结果与理论分析结果一致，证实了模型的准确性和可行性，这种逻辑与模拟结合的简明通用的模型可以高效辅助Boost电路设计并为参数优选打下了基础。

But his Nixonian smear campaign against critics of the Justice Department was way out of bounds. And his unrepentant defense of dumpster-diving private investigations was almost beyond belief. At a time when Washington is deciding whether the tech industry can be trusted to respect personal privacy? Is this guy for real?

Larry Ellison在其演讲中宣称，Oracle的Fusion中间件要比SAP的NetWeaver 产品"领先数年时间"，而且由于SAP 将其软件更新版本一直推迟到了2010年，这也使得SAP在应用软件方面也要落后Oracle整整两年时间。

Carleman不等式及其在最优控制问题中的应用.Optimal control theory of distributed parameter systems mainly includes: Pontryagin's maximum principle; controllability; Hamilton-Jacobi equation (i.e., dynamic programming equation); time optimal control, etc.In this dissertation, we establish Pontryagin's maximum principle of optimal control problems governed by some nonlinear differential equations (parabolic differential equations, elliptic differential equations and 3-dimensional Navier-Stokes equations), which in particular could have local solut...

在这篇博士论文中，我们建立了非线性微分方程(包括抛物型微分方程，椭圆型微分方程以及3维Navier-Stokes方程)最优控制问题的庞特里雅金最大值原理，特别地，这些方程可能只有局部解或存在多解(我们称这样的系统为非适定系统，相应的最优控制问题为非适定最优控制问题)，以及适定的非线性发展方程最优控制问题的庞特里雅金最大值原理；我们研究了phase-field系统的时间最优控制问题以及Boussinesq系统的局部内可控性。

In the heredity community renewal process, the paper uses one kind of new crossover operator——Improvement Order Crossover, the better solution two difficult problems both has been able to maintain the fine characteristic of father generation, does not destroy the sub-way which produces already in the most superior routing, and can guarantee when participation in the crossover two individual body is same, causes the genetic algorithms not to be able precociously to restrain in the partial optimal solution.

在应用遗传算法求解时，提出采用惩罚策略处理目标函数中对车辆容量的限制和客户对不同时间窗的需求约束，从而使目标解所对应的染色体能够根据违反约束的程度，具有不同大小的适应度；在遗传群体更新过程中，本文采用一种新型的交叉算子——改进的顺序交叉，更好的解决了既不破坏父代染色体中已产生的最优子路径，还能保证当参与交叉的两个个体相同时，遗传算法不会早熟收敛于局部最优解的两个难题。
