Well suited to medium-scale general purpose computing, the Unix time sharing operating system is deservedly popular with academic institutions, research laboratories, and commercial establishments alike. Its user com munity, until recently a brotherhood of experienced computer profes sionals, it now attracting many people concerned with computer appli cations rather than the computer systems themselves. This book is intended for that new audience, people who have never encountered the Unix system before but who do have some acquaintance with computing. While helping beginning users get...

This third edition of the principal text on the finite element method for electrical engineers and electronics specialists presents the method in a mathematically undemanding style, accessible to undergraduates who may be encountering it for the first time. Like the earlier editions, it begins by deriving finite elements for the simplest familiar potential fields, and then formulates finite elements for a wide range of applied electromagnetics problems. These include wave propagation, diffusion, and static fields; open-boundary problems and nonlinear materials; axisymmetric, planar and fully...
