  • The field of industrial electronics covers a plethora of problems that must be solved in industrial practice. Electronic systems control many processes that begin with the control of relatively simple devices like electric motors, through more complicated devices such as robots, to the control of entire fabrication processes. An industrial electronics engineer deals with many physical phenomena as well as the sensors that are used to measure them.

  • An updated approach to reference frame analysis of electric machines and drive systems Since the first edition of Analysis of Electric Machinery was published, the reference frame theory that was detailed in the book has become the universally accepted approach for the analysis of both electric machines and electric drive systems. Now in its second edition, Analysis of Electric Machinery and Drive Systems presents, in one resource, the application of this theory to the analysis, simulation, and design of the complete drive system including the machine, converter, and control....

  • This text started out many years ago as a lab-based text, one of the first such published by ISA—titled Basic Electrical Measurements and Calibration—in 1978, nearly 28 years ago. Many things in the electrical/ electronics industry have changed since this first edition was published. In the years following publication, digital instrumentation has become affordable, widespread, and has almost totally displaced analog devices in automation. While analog instruments have not completely disappeared, it is no longer the technology of choice for current automation installations....

  • This book will discuss the topic of Control Systems, which is an interdisciplinary engineering topic. Methods considered here will consist of both "Classical" control methods, and "Modern" control methods. Also, discretely sampled systems (digital/computer systems) will be considered in parallel with the more common analog methods. This book will not focus on any single engineering discipline (electrical, mechanical, chemical, etc), although readers should have a solid foundation in the fundamentals of at least one discipline....

  • © National Instruments Corporation I-1 Fundamentals of Digital Electronics Introduction Digital electronics is one of the fundamental courses found in all electrical engineering and most science programs. The great variety of LabVIEW Boolean and numeric controls/indicators, together with the wealth of programming structures and functions, make LabVIEW an excellent tool to visualize and demonstrate many of the fundamental concepts of digital electronics.

  • This book is concerned with the subject of Wind Energy, as a source of clean and renewable and free for all. The need for this type of book is very well documented, the current consumption of energy is unsustainable and humans have to change their habits and or utilise this source, but there is so much work before we can rely completely on renewable energy. This book aims to describe the fundamentals of wind energy and the pertinent parameters that control the amount of energy available from a given wind turbine. Coal fuelled the industrial revolution in the 18th and 19th century.

  • Digital electronics is one of the fundamental courses found in all electrical engineering and most science programs. The great variety of LabVIEW Boolean and numeric controls/indicators, together with the wealth of programming structures and functions, make LabVIEW an excellent tool to visualize and demonstrate many of the fundamental concepts of digital electronics. The inherent modularity of LabVIEW is exploited in the same way that complex digital integrated circuits are built from circuits of less complexity, which in turn are built from fundamental gates.

  • While most HVAC designers will have the support of a competent electrical design staff, it is important to understand certain fundamentals of electricity, power distribution, and utilization, because so many HVAC system devices are mechanically driven and controlled. This book cannot present electrical topics in great detail, but it can address several common topics and refer to more definitive works.

  • The title of this textbook, Biosensors: From Electric Circuits to Immunosensors, implies that we are going to learn both electric circuitry (in relation to conventional sensors such as temperature sensors) and biosensors (such as antibody-based immunosensors). The idea of putting these two topics together into a single book came from my decision to add biosensor topics to the “Sensors and Controls” class taught at the University of Arizona. At that time, I realized there was no available textbook that equally addressed these two topics.
