The course gives an overview of different types of electrical machines and drives. Different types of mechanica loads are discussed. Maxwell's equations are applied to magnetic circuits including permanent magnets. DC machines, induction machines, synchronous machines, switched reluctance machines, brushless DC machines and single-phase machines are discussed with the power electronic converters used to drive them.Study Goals After following this course the students should have an overview over the different types of electrical machines and the way they are used in drive systems and they should be able to derive equations describing the steady-state performance of these machines

European gas and electricity markets have largely been liberalized. Due to the specific physical characteristics and public interest aspects of electricity and gas, and to the fact that the networks continue to be natural monopolies, these markets require careful design. In this class, it is analyzed what the market design variables are and how the ongoing process of market design depends on policy goals, starting conditions and physical, technical and institutional constraints. In addition, a number of current policy issues will be discussed, such as security of supply, the CO2 emissions market, the integration of European energy markets and privatization. Participation in a simulation game, in which long-term market dynamics are simulated, is mandatory.

This collection uses primary sources to explore the introduction of electric power to the United States. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

Electromagnetics Volume 1 by Steven W. Ellingson is a 225-page, peer-reviewed open educational resource intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wage equations for voltage and current.

This book contains eight chapters. Chapter Two briefly describes the technology that makes electronic commerce possible, while Chapter Three introduces the topic of Web strategy. The major functions of marketing are described in the next five chapters: Promotion (Chapter Four); Promotion and Purchase (Chapter Five); Distribution (Chapter Six); Service (Chapter Seven); and Pricing (Chapter Eight). The final chapter takes a broader, societal perspective and discusses the influence of electronic commerce on society.

This unit describes the overview and introduction to the electronic health record (EHR).

This course is a basic course on Instrumentation and Measurement. Firstly, the detection limit in a typical instrument for measurement of an electrical quantity is determined for: offset, finite common-mode rejection, noise and interference. The dominant source of uncertainty is identified and the equivalent input voltage/current sources are calculated. Secondly, the measurement of a non-electrical quantity is discussed. In this case the detection limit should be expressed in terms of the non-electrical input parameter of interest. Issues discussed are: (cross-)sensitivities in frequently used transduction effects, non-electrical source loading and noise in the non-electrical signal domain. Coupled domain formal modeling is subsequently introduced to facilitate analytical multi-domain system analysis. Finally, the detection limit in typical applications in the mechanical, thermal, optical and magnetic signal domain are analysed, along with circuit and system techniques to maximize overall system detectivity.

This course is an introduction to power electronics. First the principles of power conversion with switching circuits are treated as well as main applications of power electronics. Next the basic circuits of power electronics are explained, including ac-dc converters (diode rectifiers), dc-dc converters (non-isolated and isolated) and dc-ac converters (inverters). Related issues such as pulse width modulation, methods of analysis, voltage distortion and power quality are treated in conjunction with the basic circuits. The main principles of operation of most commonly used power semiconductor switches are explained. Finally, the role of power electronics in sustainable energy future, including renewable energy systems and energy efficiency is discussed.

Study Goals
To get acquainted with applications of power electronics, to obtain insight in the principles of power electronics, to get an overview of power electronic circuits and be able to select appropriate circuits for specific applications and finally to be able to analyse the circuits. The focus in the course is on analysis and to a lesser extent on design.

This book is not intended for budding mathematicians. It was created for a math program in which most of the students in upper-level math classes are planning to become secondary school teachers. For such students, conventional abstract algebra texts are practically incomprehensible, both in style and in content. Faced with this situation, we decided to create a book that our students could actually read for themselves. In this way we have been able to dedicate class time to problem-solving and personal interaction rather than rehashing the same material in lecture format.

Elementary Algebra is designed to meet the scope and sequence requirements of a one-semester elementary algebra course. The book’s organization makes it easy to adapt to a variety of course syllabi. The text expands on the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Each topic builds upon previously developed material to demonstrate the cohesiveness and structure of mathematics.
