一款基于J2EE轻量级架构的社区系统，具有如下特点： 表示层：基于Apache Tapestry组件化页面技术，对客户界面进行模块设计。由于页面模板中只有简单的类似if-else和for 循环逻辑，并且所有标签都是标准的HTML标签，因此页面可以放在任何所见所得的HTML编辑器中进行很轻松的编辑、美化。当然，Tapestry只是整个系统的表现部分，如果需要，此部分也可由其它技术实现，如JSP，velocity等。 权限系统：在客户界面与业务核心层间，存在一套完整的权限系统。每个用户在系统中都有自己的权限，这些权限细致限定了该用户可以使用哪些服务或者可以访问哪些业务对象。 过滤器系统：此系统由一系列过滤器组成，对表示层要显示的社区内容执行过滤。 社区核心层：这里完成几乎所有的业务逻辑。 后台数据库系统：存储社区各项数据。数据层服务由Hibernate提供数据连接。 模块化、可配置、伸缩性强：您可广泛程度上的定义多数社区子系统：如用户、组、权限系统、过滤器、拦截器、等级积分算法、社区属性(如体力值、魅力值)等。

非常好的优化算法的书，详细介绍了蚁群算法和粒子群算法以及相关的matlab工具箱，讲了理论和应用给出了工具箱的下载地址。 Swarm intelligence is an innovative computational way to solve hard problems. In particular, particle swarm optimization, also commonly known as PSO, mimics the behavior of a swarm of insects or a school of fish. If one of the particle discovers a good path to food the rest of the swarm will be able to follow instantly even if they are far away in the swarm. Swarm behavior is modeled by particles in multidimensional space that have two characteristics: a position and a velocity. These particles wander around the hyperspace and remember the best position that they have discovered. They communicate good positions to each other and adjust their own position and velocity based on these good positions.

GPS 接收程序 DEMO。 HsGpsDll Library 1.1 A GPS Control/Component for C/C++ HsGpsDll is a Windows Dynamic Link Library which provides access to any NMEA-183 compliant GPS receiver via a serial communications port. HsGpsDll is designed for use from Visual C, Visual Basic or other languages, capable of calling DLL functions. HsGpsDll allows a user application to read from a GPS device the current GPS position fix, velocity over ground (speed in kilometers per hour), plus number of of sattelites in view, current altitude (against mean sea level) and UTC date and time

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.
