MPEG Layer Ⅲ Decoder Design Based on DSP     

LUO Jun  FU Li 《保鲜与加工》2005,(1):28-31

The design of MP3 decode system based on DSP is introduced. TLV320AIC23, a high performance and stereo codec chip, is selected as a D/A converter in the system. Two McBSPs ofDSP are connected to TLV320AIC23, one of them acts as configuration interface, the other ,the audio digital interface. Configuration interfacemode is SPI. The MP3 audio bitstreamtransmissionbetween the PC and DSP isrealized through the USB1.1 interface. So it is convenientto access MP3 audio bitstream. A large capacitymemory device, Compact Flash Card , is a storage media accessing MP3 bitstream.a programmable logical device, CPLD, controls reading, writing and chip selection of USB and Compact Flash Card. Some experiments show the systemcan well accomplish MP3 decodingand playing.  相似文献   

Review on Synthesis Refrectory Nanoparticles     

HUANG Xin  LIU Qing-cai  SUN Ya-li  LUO Jun 《保鲜与加工》2005,(2):55-58

In general, the process of synthesis the refractory nanoparticles Is classified as solid state, liquid state and gaseity. The new progress and development in the study of refractory nanoparticles are investigated. The synthesis technology of the refrectory nanoparticle in liquid state is discussed mostly. The refrectory nanoparticles is synthesized by the liquid state. The characteristics and the structure of the refrectory nanoparticles have been studied in this paper.  相似文献

An EOQ Model Taking Account of the Variable Selling Price Under Stock Dependent Selling Rate     

LUO Bing  YU Hui qiang 《保鲜与加工》2002,(11):100-103

In 1995, Padmanabhan and Vrat presented inventory models for deteriorating items with a constant selling price and stock dependent selling rate . Based on the result, in 2000, Kun-Jen Chung, Peter Chu and Shaw-Ping Lan devoloped the necessary and sufficient conditions of the existence and uniqueness of the optimal solutions of the profit per unit time functions without backlogging and with complete backlogging. Actually, the selling price need not be constant, it may be variable . This paper puts forward an EOQ model when the selling price is variable without backlogging, discusses the existence and uniqueness of optimum solution. The example is provided to illustrate the model. The theoretical evidence is provided for the inventory system to make management decision.  相似文献   

A Medical Image Quantization Method Suited for PACS     

LI Qing hui  PENG Cheng lin  HOU Wen sheng  LUO Xiao gang 《保鲜与加工》2002,(3):78

Image compression is very important in picture archiving and communication system(PACS). The author studied the statistical distribution of image wavelet subimage coefficients and concluded that the distribution of wavelet subimage coefficients is similar to that of Laplasian distribution. On the other hand, in image reconstruction, the coefficient with different amplitude owns different weight, and different accuracy can be applied to different coefficients according to their different weight. Then, the author has designed a image quantization encoding scheme for PACS. In this scheme, they selected the sample-standard-deviation of coefficients in every subimage as the quantization threshold, and accurately encoded those coefficients with higher weight. Also, this algorithm utilized the visual character of human. The test has proved that the main advantages of this method are the simplicity in computing and predictable encoded coefficients, and a high compression efficiency can obtain too.  相似文献   

An EOQ Model at Random when Average Demand Is a Linear Increasing Function     

LUO Bing  YANG Xiu Tai  XIONG Zhong Kai 《保鲜与加工》2002,(5):131-135

For certain types of inventory, the ordering cycle and demand may be random variants, which satisfy certain types distribution. The classical EOQ model usually neglects the fact. Based on the constant demand, under the hypothesis that the ordering cycle is a random variant which satisfies exponent distribution, average demand is a linear increasing function, this paper considers the effects of the time-value of capital and inflation on replenishment strategy of inventory system. Loosening the condition of basic economic order quantity model under deterministic state, the total cost function of the model is provided. The optimum order quantity and cycle are obtained. The application range of EOQ model under the constant demand is widened. The theoretical evidence is provided for the inventory system to make management decision.  相似文献   

EPQ Model with Different Lost Sale Factor Relative to Inventory Level     

LUO Bing  LI Yu-yu  HUANG Bo 《保鲜与加工》2006,(12):125-129

It is important for enterprises' inventory management to find out the optimal production cycle and the length of shortage time,so that the total cost of inventory system can be reduced and the service level can be raised.Based on the classical EPQ model,this paper develops an EPQ model for deterioration items with different lost sale factor relative to the inventory level during shortage period.The existence of unique optimal solution is discussed by mathematic analysis and a numeric example.The sensitivity analysis shows that the parameter of losing sale has different impact on the costs of inventory system.The factors must be considered for the production inventory system to make management decision.  相似文献
