We introduce a sub-cell WENO reconstruction method to evaluate spatial derivatives in the high-order ADER scheme. The basic idea in our reconstruction is to use only r stencils to reconstruct the point-wise values of solutions and spatial derivatives for the 2r-1 th order ADER scheme in one dimension, while in two dimensions, the dimension-by-dimension sub-cell reconstruction approach for spatial derivatives is employed. Compared with the original ADER scheme of Toro and Titarev (2002) [2] that uses the direct derivatives of reconstructed polynomials for solutions to evaluate spatial derivatives, our method not only reduces greatly the computational costs of the ADER scheme on a given mesh, but also avoids possible numerical oscillations near discontinuities, as demonstrated by a number of one- and two-dimensional numerical tests. All these tests show that the 5th-order ADER scheme based on our sub-cell reconstruction method achieves the desired accuracy, and is essentially non-oscillatory and computationally cheaper for problems with discontinuities.

该类方法主要指的是活动轮廓模型(active contour model)以及在其基础上发展出来的算法,其基本思想是使用连续曲线来表达目标边缘,并定义一个能量泛函使得其自变量包括边缘曲线,因此分割过程就转变为求解能量泛函的最小值的过程,一般可通过求解函数对应的欧拉(Euler.Lagrange)方程来实现,能量达到最小时的曲线位置就是目标的轮廓所在。

LINQ to SQL和Entity Framework都是一种包含LINQ功能的对象关系映射技术。他们之间的本质区别在于EF对数据库架构和我们查询的类型实行了更好的解耦。使用EF,我们查询的对象不再是完全对应数据库架构的C#类,而是更高层的抽象:Entity Data Model。这为我们提供了额外的灵活性,但是在性能和简单性上面也会有所损失。

We show in the context of a new economic geography model that when labor is heterogenous trade liberalization may lead to industrial agglomeration and inter-regional trade. Labor heterogeneity gives local monopoly power to firms but also introduces variations in the quality of the job match. Matches are likely to be better when there are more firms and workers in the local market, giving rise to an agglomeration force which can offset the forces against, trade costs and the erosion of monopoly power. We derive analytically a robust agglomeration equilibrium and illustrate its properties with numerical simulations

最近在学习Oracle,对测试人员而言必须掌握两种语言:第一种是DML,数据操纵语言 (Data Manipulation Language) 是SQL语言中,负责对数据库对象运行数据访问工作的指令集,以INSERT、UPDATE、DELETE三种指令为核心,分别代表插入、更新与删除。第二种是:DQL,数据查询语言 (Data Query Language) 是SQL语言中,负责进行数据查询而不会对数据本身进行修改的语句,这是最基本的SQL语句。核心指令为SELECT,以及一些辅助指令,如FROM、WHERE等,FROM:表示来源,可以搭配JOIN做链接查询; WHERE:过滤条件;GROUP BY:在使用聚合函数时用到,如SUM,COUNT,MAX,AVG;HAVING:对聚合结果进行筛选,这是和WHERE的不同点;ORDER BY:排序。
