简介：　　Abstract: This paper studies the random access procedure and collision resolution procedure of stack algorithm in mobile communication system at first, and then theoretically analyses the throughput parameter of stack algorithm. This article simulates the random access procedure with slotted-ALOHA and stack collision resolution algorithms, and especially simulates two stack algorithms Free Access stack algorithm and stack algorithm with power capture, and finally compares the performance characteristics between stack algorithms.

简介：Summary: Publisher Summary 1 This text provides students with an understanding to support statistical analysis and decision making in business and economics. Coverage includes data analysis, probability and random variables, correlation and regression, nonparametric statistics, time series analysis, and statistical decision theory. This fifth edition includes computer applications and interpretation, with a new CD-ROM containing PHStat2, a software program with 50 macros for using Microsoft Excel to solve most of the problems in the text. The CD-ROM also contains data sets for examples and problems. Newbold is affiliated with the University of Nottingham. Annotation c. Book News, Inc., Portland, OR (booknews.com)   Publisher Summary 2 The strength of this book has been its unerring accuracy and statistical precision. The role of computers and statistical software has been thoroughly integrated throughout. This edition focuses on maintaining the statistical integrity of past editions while modernizing the book by integrating the use of statistical software, adding new examples and exercises (many with real data), and an emphasis on data analysis and interpretation of output. The fifth edition features both Excel and Minitab. Earlier introduction of key topics includes: introduction of statistical thinking (Ch. 1), introduction of processes and systems (Ch. 1), and coverage of bivariate data, scatter plots, regression, covariance, and correlation (Ch. 3).

简介：Pratt, one of the primary developers of the Programmers Imaging Kernel System (the program included on the CD), offers an introduction to the field of digital image processing for students in electrical engineering or computer science, as well as practitioners. His objective is to provide the PIKS software and summarize the most important contributions to the field in one volume. Topics cover the characterization of continuous images, sampling and quantization, signal processing, enhancement and restoration, analysis, and software implementation. New to this edition are sections on color image sampling systems, contrast manipulation, polar coordinate conversion, and other topics. The CD also includes C program source demonstration programs and a digital image database of most of the images in the book. Background in linear systems theory, vector space algebra, and random processes is assumed. Topics related to the field, such as pattern recognition, image understanding, and coding, have been omitted. Annotation 漏2007 Book News, Inc., Portland, OR (booknews.com)
