Compression Assignment Kanwar Ahmad Mustafa Department Of Electronics and Communication The University of Lahore 1-Km Thokar Raiwand Road Lahore‚ Pakistan punjabians50@hotmail.com Abstract—Signal compression is concern with the reduction of amount of data i.e.‚ efficient transmission speed of data can be achieved. Redundant data is removed in compression and added during decompression. It includes different techniques which help to get the job done. These techniques include Lossless and

DATA COMPRESSION The word data is in general used to mean the information in digital form on which computer programs operate‚ and compression means a process of removing redundancy in the data. By ’compressing data’‚ we actually mean deriving techniques or‚ more specifically‚ designing efficient algorithms to: * represent data in a less redundant fashion * remove the redundancy in data * Implement compression algorithms‚ including both compression and decompression.

DUAL EVAPORATOR SYSTEM DUAL EVAPORATOR SYSTEM What is a “Dual Evaporator System” ? As far as we know there is no classic definition for dual evaporator system. The two evaporators may be connected in different ways with the capillary tube(s) and compressor. Aditional valves are required depending on the system assembly. The most used ones are the directional valve at the end of the condenser and /or a check valve at the end of the freezer compartment. In some systems there is no connection

Except for zero‚ all Arabic digits are polysyllabic words. In this paper Arabic digits were investigated from the speech recognition problem point of view. An artificial neural network based speech recognition system was designed and tested with automatic Arabic digit recognition. The system is an isolated whole word speech recognizer and it was implemented as both a multi-speaker and speaker-independent modes. During the recognition process‚ noise was removed from digitized speech by means of band-pass

PREPARATION FOR: "MACPHERSON REFRIGERATION LIMITED" CASE Read the case‚ and answer the following questions: 1. Search in the library (books on Operations Management or Production Management)‚ to find the main components of the “Aggregate Production Planning” problem and briefly describe which are “pure strategies” and “mixed strategies” to solve this problem. The aggregate demand is the total demand for all products/services produced by a production facility without considering size‚ models

Vertebral Compression Fracture (Thoracic) Overview- The spine is made up of bones called vertebrae. A vertebra can crack just like any other bone in the body. When the vertebral body collapses‚ this is called a vertebral compression fracture. These fractures occur more frequently in the thoracic spine (the central portion of the spine)‚ in particular in the lower part. These fractures are generally caused by a condition such as osteoporosis‚ a very hard fall‚ or another type of injury. Causes- The

Manufacturing Systems Project . Topic : How to manufacture a Refrigerator for long distance transporation of goods. 1.0 Introduction : This project will look at the manufacturing processes involved in producing a refrigerator that allows perishable goods to be transported over long distances. In reality we owe our great choice of foods in supermarkets to this invention. Companies like Thermo King from America have been making refrigerators for many years and are a large supplier of them to

3.1 Principle of Refrigeration[16]: Mechanical refrigeration is done by three processes that are circulation‚ evaporation‚ and condensing a fixed supply of refrigerant in a closed system. Evaporation takes place at a low temperature and low pressure while condensation occurs at a high temperature and high pressure. Thus‚ it is possible to transfer heat from an area of low temperature (i.e.‚ water storage tank) to an area of high temperature (i.e.‚ environment). Regarding to the fig 3.1‚ beginning
