Probability and Random Processes for Electrical and Computer Engineers

Hardback (ISBN-13: 9780521864701 | ISBN-10: 0521864704)
available from June 2006

Courses: Probability and Random Processes (as a primary text) - graduate level - Electrical and Computer Engineering Departments. Wireless Communications (as a background text in probability) - graduate level - Electrical and Computer Engineering Departments. Also suitable for advanced undergraduates.
The theory of probability has important applications for computer and electrical engineers as a tool to explain, model, analyse and design the technology they develop. Consequently, a course in probability and random processes is a prerequisite for further study in communications or signal processing. Gubner presents a primary text that progresses from advanced undergraduate level, assuming a modest knowledge of probability, through to the more complex topics suitable for graduates, including random vectors, Gaussian random vectors, random processes and Markov chains. Describing tools and results that are used extensively in the field, this is more than a textbook: it is also a valuable reference for researchers working in communications, signal processing, and computer network traffic analysis. With chapter outlines, over 300 worked examples, some 800 problems and sections for exam preparation, this is an essential companion for advanced undergraduate and graduate students.

* Each chapter contains a eNotesf section at the end to discuss the more techincal points of theory

* There are worked examples throughout the main text, accompanied by homework problems (800 in total) and exam preparation at the end of each chapter: a number of examples and problems use MATLAB

* The book is structured such that instructors can target the level (undergraduate or graduate) of the course to suit the background of the students

Random Fragmentation and Coagulation Processes

Series: Cambridge Studies in Advanced Mathematics (No. 102)
Hardback (ISBN-13: 9780521867283 | ISBN-10: 0521867282)
available from July 2006

Fragmentation and coagulation are two natural phenomena that can be observed in many sciences and at a great variety of scales - from, for example, DNA fragmentation to formation of planets by accretion. This book, by the author of the acclaimed Levy Processes, is the first comprehensive theoretical account of mathematical models for situations where either phenomenon occurs randomly and repeatedly as time passes. This self-contained treatment develops the models in a way that makes recent developments in the field accessible. Each chapter ends with a comments section in which important aspects not discussed in the main part of the text (often because the discussion would have been too technical and/or lengthy) are addressed and precise references are given. Written for readers with a solid background in probability, its careful exposition allows graduate students, as well as working mathematicians, to approach the material with confidence.

* Author is the world-leading expert on the field and a great expositor

* The first book on an important class of stochastic models

* Wide-ranging areas of application - computer science, physics, geophysics, biology and more

Contents

Introduction; 1. Self-similar fragmentation chains; 2. Random partitions; 3. Exchangeable fragmentations; 4. Exchangeable coalescents; 5. Asymptotic regimes in stochastic coalescence; References; List of symbols; Index.

Lectures on the Combinatorics of Free Probability

Series: London Mathematical Society Lecture Note Series (No. 335)

Free Probability Theory studies a special class of enoncommutativefrandom variables, which appear in the context of operators on Hilbert spaces and in one of the large random matrices. Since its emergence in the 1980s, free probability has evolved into an established field of mathematics with strong connections to other mathematical areas, such as operator algebras, classical probability theory, random matrices, combinatorics, representation theory of symmetric groups. Free probability also connects to more applied scientific fields, such as wireless communication in electrical engineering. This book is the first to give a self-contained and comprehensive introduction to free probability theory which has its main focus on the combinatorial aspects. The volume is designed so that it can be used as a text for an introductory course (on an advanced undergraduate or beginning graduate level), and is also well-suited for the individual study of free probability.

* Presents the state of the art of the combinatorial facet of free probability

* Gives a friendly and self-contained introduction to the general field of free probability

* Written in a style which makes it ideal for use in the presentation of a graduate level course

Applied Multilevel Analysis
A Practical Guide for Medical Researchers

This is a practical introduction to multilevel analysis suitable for all those doing research. Most books on multilevel analysis are written by statisticians, and they focus on the mathematical background. These books are difficult for non-mathematical researchers. In contrast, this volume provides an accessible account on the application of multilevel analysis in research. It addresses the practical issues that confront those undertaking research and wanting to find the correct answers to research questions. This book is written for non-mathematical researchers and it explains when and how to use multilevel analysis. Many worked examples, with computer output, are given to illustrate and explain this subject. Datasets of the examples are available on the internet, so the reader can reanalyse the data. This approach will help to bridge the conceptual and communication gap that exists between those undertaking research and statisticians.

* Non-mathematical approach

* Computer output of all examples

* Comparison between software packages
