一款基于J2EE輕量級架構的社區系統,具有如下特點: 表示層:基于Apache Tapestry組件化頁面技術,對客戶界面進行模塊設計。由于頁面模板中只有簡單的類似if-else和for 循環邏輯,并且所有標簽都是標準的HTML標簽,因此頁面可以放在任何所見所得的HTML編輯器中進行很輕松的編輯、美化。當然,Tapestry只是整個系統的表現部分,如果需要,此部分也可由其它技術實現,如JSP,Velocity等。 權限系統:在客戶界面與業務核心層間,存在一套完整的權限系統。每個用戶在系統中都有自己的權限,這些權限細致限定了該用戶可以使用哪些服務或者可以訪問哪些業務對象。 過濾器系統:此系統由一系列過濾器組成,對表示層要顯示的社區內容執行過濾。 社區核心層:這里完成幾乎所有的業務邏輯。 后臺數據庫系統:存儲社區各項數據。數據層服務由Hibernate提供數據連接。 模塊化、可配置、伸縮性強:您可廣泛程度上的定義多數社區子系統:如用戶、組、權限系統、過濾器、攔截器、等級積分算法、社區屬性(如體力值、魅力值)等。

非常好的優化算法的書,詳細介紹了蟻群算法和粒子群算法以及相關的matlab工具箱,講了理論和應用給出了工具箱的下載地址。 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.
