一.编排业务逻辑的模式1. 事务脚本模式TS(The Transaction Script pattern ) TS模式概述     TS 鼓励你跳过任何的面向对象的设计,你直接到所需的用户操作的业务组件映射.专注于的业务用户可以通过表示层完成,并为每个请求编写方法.这个方法被称之为事务脚本,此处事务通常是指想要进行商业交易,脚本是指系统中的一系列关系用户操作的系统操作.     TS历时多年仍然不过时的原因只有一个:它基于推行可视化的业务逻辑设计,而可视化正上用户体验的核心.     在TS中…

Theorem 19.6 Let \(f: A \rightarrow \prod_{\alpha \in J} X_{\alpha}\) be given by the equation \[ f(a) = (f_{\alpha}(a))_{\alpha \in J}, \] where \(f_{\alpha}: A \rightarrow X_{\alpha}\) for each \(\alpha\). Let \(\prod X_{\alpha}\) have the product…

1.空间域噪声类型 1.gauss+possion 2.椒盐噪声(dpc处理已经处理了) 去除空域噪声有哪些方法? 空域噪声一般的思想是对某pixel邻域的pixels进行加权平均. 比如 1.高斯降噪(和像素无关,只和距离有关) 并没有去除噪音,只是smooth图像. 2.双边滤波(不仅和距离有关,还和相邻像素的相似度有关(如果pixel值接近则权重几乎不衰减)) 比高斯滤波好一些 3.非局部滤波(前面只考虑某个pixel邻域n*n的像素,没有考虑其他"邻域的邻域",非局部滤波就是考…

Introduction Many approaches to object oriented modeling tend not to scale well when the applications grow in size and complexity. Context Mapping is a general purpose technique, part of the Domain Driven Design (DDD) toolkit, helps the architects an…

For a normed space \(X\), an isometric isomorphism can be defined from \(X\) to its second dual space \(X''\), i.e. \(J: X \rightarrow X''\), such that for all \(x \in X\), \(J(x) = J_x\) with \(J_x\) being defined as \(J_x(x') = x'(x) \; (\forall x'…

Abstract The recent success of deep neural networks relies on massive amounts of labeled data. For a target task where labeled data is unavailable, domain adaptation can transfer a learner from a different source domain. In this paper, we propose a n…
