videocompressionpaper
本论文首先系统地介绍了视频压缩编码的基本原理和方法，以及各国际标准
化组织提出的压缩标准；其次分析了JPEG和MPEG-4的主要技术，据此提出
MPEG-4简单框架编码器的软件实现方案，给出流程图，在VC++环境下用C语言
程序实现了JPEG压缩及MPEG-4简单框架的视频压缩功能，采用测试序列验证
无误，并对两种标准的压缩比进行试验对比，突出压缩的关键技术为DCT和运动
估计算法；接着深入研究了DCT变换、运动估计和补偿算法并进行了优化改进，
给出了用于快速匹配块的自适应十字模式搜索算法，并给出了对各种块匹配估计
算法的仿真结果。然后详细介绍了TI公司TMS320C6711DSP的软硬件特性，并
在此基础上提出系统的硬件实现方案。接着介绍了基于系统软硬件环境的移植问
题和优化方法，并针对算法移植和仿真过程中的问题进行了说明。
最后就课题设计过程中研究的结果予以总结，并阐述了以后课题研究的要点。(In this thesis,an introduction to video compression principal,methods and central
international video coding standards is done firstly.Then analyzing the core techniques
of JPEG and MPEG-4 and proposing a scheme of MPEG-4 SP encoder,the coding
function of JPEG and MPEG-4 is achieved in C successfully with test sequence Then
compare the compressed ratio of two standards,point out the key of compression is DCT
and Motion Estimation algorithm.Afterwards,studying the DCT/Motion
Estimation/Motion Compensation algorithm in detail and giving an adaptive rood
pattern search for fast Block-Matching motion estimation.Then the simulation of several
motion estimation algorithms based block-matching is given.Accordingly,a scheme of
a DSP-based video compression system is put forward,with the features of TI’s
TMS320C6711 DSP.At last,the transplant and optimization are considered on the basis
of soft and hard environments,also the simulation process.
In the end,the summarization about the)

Fluent_technology_and_example
本书基于Fluent 6.2.16版本、Gambit 2.2.30版本和Tecplot 10.0版本，共13章。全书首先详细介绍了Fluent软件及其相关的理论知识，然后通过典型的实例来讲解Fluent在传热、传质及流场等实际工程中的应用方法和技巧，包括运动部件的速度场模拟、UDF和UDS的使用、并行计算的设置、计算区域的绘制和边界条件的定义、Tecplot的数据处理等。每个实例都有详细的说明与详尽的操作步骤，读者只要按照书中的指示与方法操作，即可完成一个具体问题的数值模拟与分析，进而逐步掌握利用Fluent进行流体流动数值模拟的基本方法。
(Fluent 6.2.16 Based on the book version, Gambit 2.2.30 version and the version of Tecplot 10.0, Chapter 13. First of all, the book detailed the Fluent software and its related theoretical knowledge, and then through a typical example to explain Fluent in heat transfer, mass transfer and flow field, such as practical engineering methods and techniques, including the moving parts of the velocity field simulation, UDF and the use of UDS, parallel computing setting, rendering the calculation region and the definition of boundary conditions, Tecplot' s data processing. Each have a detailed description of examples with detailed steps, readers as long as the book' s instructions and in accordance with the method of operation, to complete a specific question of the numerical simulation and analysis, and gradually master the use of Fluent for numerical simulation of fluid flow of the basic method .)
