The book ¿Lectures on Electromagnetic Fields, Waves, Energy & Their Applications (With Worked Examples),¿ is put together in a conversational manner with adequate mathematical step-by-step explanations. The mathematical explanations became very necessary due to the imaginative nature of the subject. That notwithstanding, nearly all mathematical expressions have been thoroughly explained with adequate references made to their physical meanings. This, hopefully, would make readers to have a good understanding of the contents of the book. The last chapter of the book has been devoted to solving numerous examples often encountered by students in Electromagnetic Fields & Waves. It is hoped that the worked examples would enable readers to acquire deeper understanding of the subject. The book adequately covers the syllabus for B.Sc. degree requirements in Electromagnetic Fields & Waves. It would equally serve as a good refresher source for higher degree students of Electrical Engineering.

The book ¿Lectures on Transmission Lines for Electrical Engineers, (With Worked Examples)¿ is written from first principles as transmission lines are. The parameters that are inherent in the lines are brought into the fore and used articulately to model the lines for accurate representation and understanding. Electrical engineers need to familiarize themselves with the theory behind transmission lines, hence how to handle designs involving them. This book would prove to be a valuable resource for both students of electrical engineering and practicing engineers in meeting the requirements associated with transmission lines.

It would be interesting for one to acquaint himself/herself with the knowledge of how electrical energy is generated, transmitted and distributed to consumers. This book, though small in size, provides the scientific and engineering principles that come into play to make all that possible. The rigorous mathematics that often accompany most electrical engineering textbooks, have been avoided. Rather, it focuses on discussions and explanations of what¿s practically going on in the three critical areas of electrical power/energy: generation, transmission and distribution. The book provides answers to basic questions that are often asked about those three key aspects of electrical engineering.

This book has been carefully prepared to address the needs of controller selection for any application. Chapter 1 deals on the definition of Process Control Engineering and the classification of process control systems. In chapter 2, engineering models of analog controllers are presented. Chapter 3 deals on digital controllers, real ¿ time control systems and types of automatic control systems. Since there¿s a relationship between analog controllers and analog computers, chapter 4 of the book is devoted to analog and hybrid computers. In chapter 5 of the book, reliability, a very important factor in any component/equipment, is meticulously and extensively treated. Chapter 6 of the book deals on the conventional flow chart and the Algorithmic State Machine, which are both tools used in process control engineering as well as in other areas of human endeavours. In order to drive home the several concepts expressed in the book, several real ¿ life questions, (and their answers), are presented in chapter 7 of the book. It is hoped that students and practitioners of control engineering will find the book a valuable companion.

This book is intended for senior level undergraduate and postgraduate students taking control engineering either as a major or service course. The practicing engineer would equally find it valuable. It will surprise readers if I state that unknown to a lot of people, control engineering principles are similar to all human, physical, physiology, biological, mental and economic activities. It can hence be stated that control engineering took after nature in ¿sensing¿ and ¿regulating¿ activities hence ensuring that what is required is what is obtained. To support these facts, basic terms commonly met in control engineering, have been defined in this book, solved examples have also been presented as guidance to readers.

The book, ¿Advanced Electronic Circuits for Engineers, (with worked Examples),¿ is meant for higher level students of Electrical/Electronic Engineering and practicing Electrical/Electronic engineers. It is written from several years of experience acquired in teaching Electrical/Electronic Engineering courses at the University level. The materials are carefully arranged in a sequential order of complexity in order to carry readers along. A lot of time had been devoted to solving circuit problems both diagrammatically and analytically using several mathematical approaches. Also, circuits have been synthesized and analyzed. All these are meant to demonstrate the various available methods in tackling electronic engineering problems. Several more worked examples are equally shown in the last chapter of the book. Though the primary target of the book is higher level B. Sc. Electrical/Electronic Engineering students, post-graduate students of Electrical/Electronic Engineering and practicing electronic engineers will equally find the book valuable. Several design examples have also been given in the book.

The book: ¿Lectures on Digital & Discrete-Time Control Engineering (with Worked Examples)¿ is meant to explain the rudiments of control engineering to post-graduate students; Masters and Doctorate. It is written from experience obtained from teaching digital/discrete-time control systems in the university to post-graduate systems for several years. In order to carry students along, worked examples are presented at the end of most chapters. In some chapters, as the need arises, the examples are given right in the main discussions of the subject. This is to enable students understand the subject of discussion immediately, rather than being held in suspense until the end of the chapter. Though the primary target of the book is university post-graduate students studying for Master¿s or Doctorate degrees in systems/control Engineering, higher undergraduate students taking control Engineering and Research institutes/centers will equally find the book a valuable source of information. It would also be useful to Instrumentation, Systems and Control Engineering practitioners in industry, mostly system Integrator.

In an age like ours where digital computers have taken over almost every aspect of our daily life, it is absolutely necessary for one to have a good understanding of how digital activities are carried out in digital computers and other Information & Communication Technology (ICT) devices. This book provides a ¿first ¿ principles¿ approach for the understanding of digital technology in digital electronic devices. The subject matters are carefully treated in ascending orders of complexity for easy understanding. Undergraduate and post graduate students of ICT, Electronic, Computer, & Communications Engineering would find the book valuable.
