Language in Zambia


Book Description

Originally published in 1978, this volume is divided into 3 parts. Part 1 presents an overview of the linguistic situation in Zambia: who speaks which languages, where they are spoken, what these languages are like. Special emphasis is given to the extensive survey of the languages of the Kafue basin, where extensive changes and relocations have taken place. Part 2 is on language use: patterns of competence and of extension for certain languages in urban settings, configurations of comprehension across language boundaries, how selected groups of multilinguals employ each of their languages and for what purposes, what languages are used in radio and television broadcasting and how decisions to use or not use a language are made. Part 3 involves language and formal education: what languages, Zambian and foreign, are used at various levels int he schools, which are taught, with what curricula, methods, how teachers are trained, how issues such as adult literacy are approached and with what success.







Actuators


Book Description

Authored by a team of acknowledged experts, this book presents a multidisciplinary view of the state of the art in the field of actuators. The goal of the book is to provide a comprehensive overview of the properties, applications, and potential applications of traditional and unconventional actuators, together with their corresponding power electronics. Special attention is paid to the objective assessment of competing actuator principles. The book is written primarily for designers and engineers in research and development, but will also be valuable as a textbook for students of automation engineering, mechatronics and adaptronics.
















Microwave Impedance Measurements and Standards


Book Description

A survey and discussion of well-known microwave impedance measurement techniques is presented.The discussion includes an introduction which emphasizes basic concepts and reflection coefficient-VSWR relationships.Sources of error in the various measurement techniques are discussed and methods to reduce errors are presented.The discussion of errors in slotted line and reflectometer * techniques is most thorough.Methods using rotating loops and resonance lines are included and a brief discussion of microwave impedance standards is given.
