基于MVC架構的網站RBAC訪問控制框架設計與實現．本此畢業設計將基于角色訪問控制（Role-Based Access Control，RBAC）作為研究課題，來實現一個企業內部管理系統中的權限管理部分。本文在RBAC2001建議標準的參考模型(下稱NIST RBAC模型)的基礎上，結合綜合信息管理系統以及軟件系統集成的要求和特點，將RBAC訪問控制框架應用到一個已有的以MVC為架構建立而成的商務網站中去。

FreeTTS is a speech synthesis system written entirely in the Java programming language. It is based upon Flite, a small, fast, run-time speech synthesis engine, which in turn is based upon University of Edinburgh s Festival Speech Synthesis System and Carnegie Mellon University s FestVox project.

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).
