查询词典 first order theory

Using the theories of probability, algebra and spectral theory comprehensively, we investigate some related characteristics of logic functions in cryptography: Firstly, we introduce m order generalized s - correlation immunity of Boolean vector functions and prove that the higher order generalized ε- correlation immunity can guarantee the lower order generalized ε- correlation immunity. Then by applying decomposition formula of joint distribution of Boolean random vectors, we give a spectrum criterion of m order generalized e - correlation immunity of Boolean vector functions. Furthermore, we show that the algebraic degree of m order generalized e - correlation immune Boolean vector functions is not restricted by the correlation immune orders.

摘 要：命令按钮是用户与计算机应用程序进行交互的最简便的方法。面向对象编程语言visual basic中的按钮控件就是命令按钮，命令按钮是应用程序中最为常用的控件，但是visual basic中的按钮控件过于简单，不够美观，支持的事件少。为实现多彩多姿命令按钮，可以利用图像框装载漂亮的图片模拟命令按钮，通过事件过程实现&命令按钮&的多种特殊效果，包括按钮的默认效果、鼠标划过时按钮的效果、鼠标单击时按钮的效果，按击回车键或逃逸键时按钮的效果。在实际编程中，设计好具有多种效果的按钮，是能否赢得用户的一件法宝。

The methods of the first-and second-order cyclic statistics-based hybrid and the first-and third-order cyclic statistics-based hybrid have been proposed. Using the first order cyclic statistics, the frequencies of harmonics corresponding to nonzero mean multiplicative noise were obtained. Then the mean of multiplicative noise can be estimated. With this, harmonics can be retrieved by second or third order cyclic statistics.
