查询词典 random access memory

Researchers have paid more attention on discretional access control,role-based access control and view based technology,rather than mandatory access control.

目前关于XML安全性的研究主要集中于自主访问控制、基于角色的访问控制和视图技术，而对于强制访问控制很少有研究。

Discretionary Access Control policy is an access control based on ownership relations between subject and object. The subject can discretionarily decide that who, by which means, can access his owned objects.

自主访问控制政策是基于客体—主体的所属关系的访问控制，主体可自主地决定其他的哪些主体可以以何种方式来访问他拥有的客体。

Among n web pages, access probability increment will decrease from the first web page to nth web page. Web pages above n will be accessed less frequently then ever. We analysed a Web server log and two proxy server logs. Analysis mainly focus on Web page request distribution, Web static document size distribution, Web static document access distance distribution, Web static doment access intertime distribution.

对一个典型的Web服务器和两个代理服务器的日志进行了分析，并将Web页面请求分布、Web静态文档大小的分布、Web静态文档的访问距离的分布、Web静态文档访问间隔时间分布同既有文献的结果进行了对比，有些结论是相同的，有些不同，可以视为我国WWW访问所特有的访问特性。

NET Framework class library. It is the backbone of partially trusted code and is not restricted to file access, but rather affects everything from network access to windowing and more. When you use it in your own component code, users will be able to execute code regardless of origin, and their systems will remain safe. This allows you to write code that is featureful, executes in native machine language, and is distributed across a LBN or even over the Internet. You can take advantage of this feature with only a minimal exposure to the underlying mechanics of code access security.

NET框架类库来施用他是半信托代码的根蒂根基而且不受限于文件拜候，可是对路程经过过程收集拜候窗户或其它的不论什么情况都有至关的影响当您在您本身的组件代码中施用它时，用户可以在不消留心来历的情况下执行代码（好比从1个英特网网站），她们的体系仿照还是是安全的这似的您可以开具富有特征的、路程经过过程本机执行的而且漫衍拜候局域网甚至是英特网的代码您可以哄骗这些特征在代码拜候安全的根蒂根基下最小限度的袒露您的信息

We can see that these come to the same thing, since if our access (to an external object, for example) is direct in sense (1), then there is nothing (at the intentional and personal level) to which we have access and in virtue of which we have access to the object.

我们能够明白这些获得的结果时一样的，因为如果我们在1意义上是直接可达的，那么在意向和人格水平，我们可以说，没有东西会是我们拥有的可达物且借助它能够可达对象。

A correlation system for Time Division Multiple Access positioning systems is disclosed, whereby a position receiver acquires, tracks, and demodulates a plurality of Code Division Multiple Access modulated positioning signals are pulsed in a Time Division Multiple Access scheme.

公开了一种用于时分多址定位系统的相关系统，借助该系统，定位接收机可以捕获、追踪和解调多个在时分多址方案中被脉冲化的码分多址调制的定位信号。

In order to satisfy the requirement of various space mission simulations and analysis, a standard interface and common service for access to the system resources, that is, resource access protocol, is designed, thus the independencies of resource storage manner and resource representation are realized. The design of resource access protocol introduced the object-oriented hierarchical method.

结合航天任务的仿真和分析对资源管理的要求，总结出资源管理系统应具备的功能和特点；从对分布式仿真资源进行高效管理和使用的角度着手，提出了基于代理的系统构建方式；进而设计了资源管理系统的体系结构，并分别探讨了体系结构的四个层次：基础资源层、通用操作环境、仿真应用接口层和管理控制层。

Brewster Kahle launched the Internet Archive in 1996. From the start it provided Open Access to its mirror of the historical Internet as well as to many special collections.The Internet Archive sponsors the Open Access Text Archive, Ourmedia (http://ourmedia.org/), and the new Open Education Resources project, and cosponsors the Open Access Million Book Project with Carnegie Mellon University.

2.1996年布鲁斯特·卡利建立了互联网档案，从此它提供了开放近用的历史档案如许多典藏，互联网档案主办机构赞助开放近用典藏，Ourmedia( http：//ourmedia.org/)，和新的开放教育资源项目，并且与卡内基梅隆大学共同赞助对一百万本书采开放近用计画。

To overcome the shortcoming of the double-way authentication access control scheme based on Harns digital signature, a new double-way authentication protocol is proposed to improve the old one. A new single-key-lock-pair access control scheme is proposed as a improved access control scheme, based on the property that a integer can be denoted into only one binary digital.

针对基于Harn数字签名双向认证访问控制实现方案中所存在的问题，运用密码技术改进了原方案的双向认证协议，并作为对原访问控制方案的改进，基于整数二进制表示的唯一性，提出了一种新的单钥-锁对访问控制方案。

The invention discloses an access control table and safety policy database method in data communication field, including: 1, initializing a Radix tree of access control table or safety policy database; 2, constructing clauses and subclauses of a rule; 3, inserting the rule in the Radix tree; 4, repeating the steps 2 and 3, in order to insert all the rules in the Radix tree, and forming the complete access control table or safety policy database; 5, searching matching rules.

本发明公开了一种数据通讯领域中访问控制列表和安全策略数据库的方法，包括：1。对访问控制列表或安全策略数据库的Radix树进行初始化；2。构造规则条目；3。将规则插入Radix树；4。重复第二步和第三步，将所有规则插入到Radix树中，形成整个访问控制列表或安全策略数据库；5。查询匹配的规则。
