Mission Foundations and other Essays
Author: S. NkhomaPublisher: African Books Collective
ISBN: 999606073X
Category : Religion
Languages : en
Pages : 325
Book Description
The first two essays in this book examine the biblical and philosophical basis for mission in the post-modern world, emphasising the experiential quality of mission over against the rational. Subsequent essays discuss various aspects of mission with a focus on the Malawian context. They highlight the impact of missionary work on the formation, shaping and developments of Malawi as a national state. Other essays examine various issues in New Testament scholarship including images of the Historical Jesus and how these relate to wisdom and apocalyptic traditions.

Book Description
This book endeavors to break the stereotype that basic electrical machine courses are limited only to transformers, DC brush machines, induction machines, and wound-field synchronous machines. It is intended to serve as a textbook for basic courses on Electrical Machines covering the fundamentals of the electromechanical energy conversion, transformers, classical electrical machines, i.e., DC brush machines, induction machines, wound-field rotor synchronous machines and modern electrical machines, i.e., switched reluctance machines (SRM) and permanent magnet (PM) brushless machines. In addition to academic research and teaching, the author has worked for over 18 years in US high-technology corporative businesses providing solutions to problems such as design, simulation, manufacturing and laboratory testing of large variety of electrical machines for electric traction, energy generation, marine propulsion, and aerospace electric systems.

Book Description
Dynamics is a science concerned with movement and changes. In the most general approach it relates to life processes as well as behavior in nature in rest. It governs small particles, technical objects, conversion of matter and materials but also concerns people, groups of people in their individual and, in particular, social dimension. In dynamics we always have to do with causes or stimuli for motion, the rules of reaction or behavior and its result in the form of trajectory of changes. This book is devoted to dynamics of a wide class of specific but very important objects such as electromechanical systems. This is a very rigorous discipline and has a long tradition, as its theoretical bases were formulated in the first half of the XIX century by d’ Alembert, Lagrange, Hamilton, Maxwell and other prominent scientists, but their crucial results were based on previous pioneering research of others such as Copernicus, Galileo, Newton... This book in its theoretical foundations is based on the principle of least action which governs classical as well as relativistic mechanics and electromagnetism and leads to Lagrange’s equations which are applied in the book as universal method to construct equations of motion of electromechanical systems. It gives common and coherent grounds to formulate mathematical models for all lumped parameters’ electromechanical systems, which are vital in our contemporary industry and civilized everyday life. From these remarks it seems that the book is general and theoretical but in fact it is a very practical one concerning modern electrical drives in a broad sense, including electromechanical energy conversion, induction motor drives, brushless DC drives with a permanent magnet excitation and switched reluctance machines (SRM). And of course their control, which means shaping of their trajectories of motion using modern tools, their designed autonomy in keeping a track according to our programmed expectations. The problems presented in the book are widely illustrated by characteristics, trajectories, dynamic courses all computed by use of developed simulation models throughout the book. There are some classical subjects and the history of the discipline is discussed but finally all modern tools and means are presented and applied. More detailed descriptions follow in abstracts for the particular chapters. The author hopes kind readers will enjoy and profit from reading this book.

Book Description
Advances During The Past Two Decades In Use Of High-Powered And Fast-Acting Solid-State Devices Has Advanced The State Of The Art Of Motor Control And Excitation Systems For Alternators; These Require The Explanation Of Harmonic Torques In Motors, As Well As The Stability Of Machines. This Book Covers The Necessary Material At The Undergraduate Level And Could Serve As A Terminal Course In Electrical Machinery Syllabus.The Book Commences With Magnetic-Circuit Calculations For Devices And Machines, Field-Plotting Methods And Principles Of Electro- Mechanical Energy Conversion For Which The Magnetic Fields Serve As Reservoirs Of Energy. The Conversion Processes Are Based On The Application Ofamperes Law Of Force And Faradays Law Of E.M. Induction, Using D Alemberts Principle Of Virtual Work. A Great Emphasis Is Placed On The Application Oflagranges Equation, Including Motional E.M.F. And The Rayleigh Dissipation Function. The Author Has Experienced That A Firm Grasp Oflagranges Method Is Most Beneficial For Handling Complex E.M.C. Problems.Chapters 3 Through 10 Cover The Basic Principles Of Operation And Performance Of Transformers, Dc Machines, Induction Motors, Synchronous Machines Leading To Discussion Of Dynamics Of Machines In The Steady State And Transient State. The Chapter On Synchronous Machines Is Strengthened By Showing The Very Basic And Important Aspect Of Calculation Of Synchronous-Machine Constants Which Is Considered Novel In Such A Book. The Student Is Given The Idea That The Flux Distribution In The Machine Is Basic To Its Operation In All Its States Of Operation.The Final Chapter Is An Introduction To Computer Aided Design Of Machines Which Is Gaining In Importance In Practice. Every Chapter Has Many Worked Examples To Guide The Student Not Only In Problem Solving But To Illustrate Engineering Aspects Of This Very Important Topic. Review Questions, Problems For Self-Testing And Objective Type Questions With All Answers Are Provided.
