Improved fast intra prediction algorithm of H.264/AVC

With advanced prediction modes of intra prediction, intra coding of H.264/AVC offers significant coding gains compared with previous video coding standards. It uses an important tool called Lagrangian rate-distortion optimization (RDO) technique to decide the best coding mode for a block, but the computational burden is extremely high. In this paper, we proposed an improved fast intra prediction algorithm including block type selection and mode decision algorithm based on analysis of edge feature of a block. Our algorithm filters out unlikely block type and candidate modes to reduce the RDO calculations. Experimental results showed that the proposed algorithm can reduce the computation complexity of intra prediction from 52.90% to 56.31%, with 0.04 dB PSNR degradation and 2% increase of bit rate.

Flow shop rescheduling problem under rush orders

INTRODUCTION Rescheduling problem in manufacturing system is considered as a particularly hard combinatorial optimization problem,closely related with uncer-tainty caused by exterior business environment and interior production conditions.Production resched-uling is a common practice in manufacturing compa-nies all over the world.Four sources of production disturbances have been identified:(1)incorrect work;(2)machine breakdowns;(3)rework due to quality problem;and(4)rush orders(Rangsarit…

近年来上海物理高考改革实例分析

素质教育要求将学生从由死记硬背造成的过重地学业负担中解放出来，要求让学生感受、理解知识产生和发展的过程，要求教育以德育为核心、以创新精神和实践能力为重点、以学生发展为目标。由此对高考内容改革提出了如何设置试卷结构，如何设计试题形式，如何确立考查目标，如何根据当前现况对教学进行平稳导向等一系列问题。这几年高考物理(上海卷)力图就上述几个方面的问题作进一步探索。

Modeling water and carbon fluxes above summer maize field in North China Plain with back-propagation neural networks

INTRODUCTION Dynamics of carbon and water vapor fluxesexchange between the atmosphere and the ecosystembiosphere, depend on complex and non-liner interplayamong physiological, ecological, biochemical andedaphic factors and meteorological conditions (Jarvis,1995; Leuning et al., 1995). There are many studiesquantifying the fluxes across different time and spacescales as well as assessing the environment con-straints on them by some kinds of biophysical orempirical models whose resul…
