A collection of multiple user credentials each associated with one of multiple different users is obtained at a device, and one or more of the multiple user credentials are verified. A determination is made as to whether access to a resource is permi…

Lab 2 System Resource Access Controls Goal: To become familiar with system resource access controls. Sequence 1: Controlling access to certain hosts Scenario: For security reasons, you have chosen to restrict your system so that it allows interactive…

In this lesson, we'll filter a list of objects based on multiple conditions and we'll use Ramda's allPass function to create a joint predicate from multiple, individual predicate functions. const R = require('ramda'); const { allPass, propEq, lte, pr…

基于多重虚拟扩展阵列的宽带信号DOA估计[1]. 宽带DOA估计是阵列信号处理领域的一个重要研究方向.在DOAs估计的实际应用中,信号总是会被噪声破坏,在某些情况下,源信号的数量大于传感器的数量,因此不能通过一些传统的算法正确地解决源问题.文中提出了一种将空间重采样和四阶累积量相结合的宽带DOAs方法——多重虚拟扩展阵列(MVEA).在信源个数大于传感器个数的情况下,MVEA能够正确地找到宽带源的方向,通过空间重采样和四阶累积量的虚拟扩展,MVEA获得了比仅采用空间重采样虚拟扩展(SRVE)的方…

2010年IEEE Secon的一篇文章.当然了,应该是之前就写好了,发表过,还是直接投到Secon了呢?直接投的吧,Secon不接受已发表过的吧. 本文的着笔点:有线网与DSAN(启用了DSA特性的WLAN)集成的情况下的TCP性能研究.就是DSAN网与传统网路通信时,其整体的TCP性能研究.场景就是“最后一英里”,典型的可以想象的是,家里的光纤到户,连一个BS,然后呢,所有的手机.PAD.Laptop等终端都通过BS上网.而这部分无线节点都启用了DSA特性,那这就是一个典型的本文要研究的一个…

今天来分析Spring的资源接口Resource的各个实现类.关于它的接口和抽象类,参见上一篇博文——Spring源码分析——资源访问利器Resource之接口和抽象类分析 一.文件系统资源 FileSystemResource 文件系统资源 FileSystemResource,资源以文件系统路径的方式表示.这个类继承自AbstractResource,并实现了写的接口WritableResource.类全称为public class FileSystemResource extends Ab…

BACKGROUND OF THE INVENTION A conventional virtual-machine monitor (VMM) typically runs on a computer and presents to other software the abstraction of one or more virtual machines. Each virtual machine may function as a self-contained platform, runn…
