  1. The performance metrics, access latency, throughput, hr hit ratio and bhr byte hit ratio are analyzed and discussed. simulations show that compared with caching only model, iwpcm can further improve the throughput, hr and bhr efficiently and reduce the access latency. the performance evaluation based on the spn model can provide a basis for implementation of web prefetching and caching and the combination of web prefetching and caching holds the promise of improving the qos of web systems

  2. If the technicians applied technology in the wrong, even achieving the business logic, but probably leading to many vices including low performance, low scalability, close coupling, low software duplication. so how to assemble the j2ee technology reasonable and achieve a system with high performance and high expansibility is my research emphasis in the thesis. in order to solve the problems and implement efficient web application, the paper put forward ejs _ mvc model according mvc pattern and we can assemble component by using ejs _ mvc model, it can solve many problems of web application and improving system with clear flow and clear function partition, in addition, due to controller is the most importance in the ejs _ mvc model, so the thesis also discuss some problems about controller design ; if the model is not designed accurately, system performance will encounter fatal influence, so the article lucubrate ejb technology from ejb choice, ejb optimized design, database access, design pattern etc and bring forward some strategies and methods about how to build efficient business tier ; finally based on ejs _ mvc model, a example that contains simple business logic is developed according to the object - orient software engineering thinking and some strategies and methods proposed by the thesis, in the process of achieving system function, the emphasis is probing into how t o assemble and apply technology reasonable and providing a new thinking thread and method contributing to build high effective and flexible j2ee application

    由於j2eeweb應用是由組件組成,因此為了解決上述問題,實現高效的應用,本文首先從如何合理組合組件入手,找到一種方法使各組件能具體分工而又緊密合作,在深入研究各組件基礎上,根據mvc模提出了ejs _ mvc模型概念,指出可按此模型組合各層組件,該模型可以解決傳統web開發中存在的問題,而且具有系統流程與系統功能劃分清晰,可擴展性、可維護性強等優點,另外由於控制器是ejsmvc模型的重中之重,它起到承上啟下的作用,它設計好壞直接關繫到整個應用的性能、伸縮性與擴展性,因此又探討了控制器設計的有關問題;另外如果模型設計不當的話,對系統性能造成的影響可能是致命的,因此本文又從ejb組件選擇、 ejb調優設計、數據庫訪問和設計模式等方面對ejb技術作了全面的分析研究,指出在業務層中如何避免太多網路遠程調用和提高業務層性能,特別是根據前面的分析總結出了業務層的優化分層組合模型,這個模型的使用無疑會使業務層具有較高的性能與伸縮性;最後選擇一個業務邏輯較簡單的系統,使注意力集中到運用的j2ee技術上來,按照ejs _ mvc模型與軟體工程流程以及本論文所提出的方法與策略實現業務邏輯,在實現過程中具體探討如何合理運用組合技術,就多層j2ee體系結構的設計思想作深入的探討實踐,為實現高效、靈活的多層j2ee應用提供一種新的思路及方法。
  3. Finally, a dynamic access system was simulated by using the algorithm based on doa estimation, the results of simulations verify the performance of smart antenna in single - cell ideal environment, and discusses the deficiency of the work and the improving way

    最後,用基於波達方向估計的演算法模擬了一個動態接入系統,模擬結果基本上驗證了理想單小區環境中智能天線的性能,並給出了不足以及改進的思路。
  4. Multi - uesr detection ( mud ) refers to signal detection in multiple access communications. this detection has many good properties, such as decreasing multiple access interference, canceling out or moderating near - far resistance, able to decrease the requirement for output control, compensating the effects due to inoptimal orthogonality, improving system performance and increasing system capacity. mud is one of the methods that can overcome the mai in cdma with most potential and complete and becomes one of the critical techniques in the third generation mobile communication
