  • Electricity+Markets+Theories

    Why did an electricity market emerge? How does it really work? What are the perfor- mance measures that we can use to tell that the electricity market under consideration is well functioning? These are the questions that will be explored in this book. The main purpose of this book is to introduce the fundamental theories and concepts that underpintheelectricitymarketswhicharebasedonthreemajordisciplines:electrical power engineering, economics, and optimization methods.

  • Electromagnetic+Transients+in+Power+Cables

    For more than a century, overhead lines have been the most commonly used technology for transmitting electrical energy at all voltage levels, especially on the highest levels. However, in recent years, an increase in both the number and length of HVAC cables in the transmission networks of different countries like Denmark, Japan or United Kingdom has been observed. At the same time, the construction of offshore wind farms, which are typically connected to the shore through HVAC cables, increased exponentially.

  • Parallel Power Electronics Filters

    Power Electronics is one of modern and key technologies in electrical and Electronics Engineering for green power, sustainable energy systems, and smart grids. Especially, the transformation of existing electric power systems into smart grids is currently a global trend. The gradual increase of distributed generators in smart grids indicates a wide and important role for power electronic converters in the electric power system, also with the increased use of power electronics devices (nonlinear loads) and motor loadings, low cost, low-loss and high-performance shunt current quality compensators are highly demanded by power customers to solve current quality problems caused by those loadings.

  • Power+Electronic+Modules+Design+Manufacture

    A power semiconductor module is basically a power circuit of different materials assembled together using hybrid technology, such as semiconduc- tor chip attachment, wire bonding, encapsulation, etc. The materials involved cover a wide range from insulators, conductors, and semiconduc- tors to organics and inorganics. Since these materials all behave differently under various environmental, electrical, and thermal stresses, proper selec- tion of these materials and the assembly processes are critical. In-depth knowledge of the material properties and the processing techniques is there- fore required to build a high-performance and highly reliable power module.

  • Smart+Power+Grids

    The electrical power grid is often referred to as one of the most complex man- made systems on Earth. Its importance to all aspects of our daily lives, economic stability, and national security cannot be overstated, and the need for an updated, secure, resilient, and smarter power grid infrastructure is increasingly recognized and supported by policy makers and market forces.

  • Wide Area Monitoring, Protection

    Today, electric power transmission systems should face many demanding chal- lenges, which include balancing between reliability, economics, environmental, and other social objectives to optimize the grid assets and satisfy the growing electrical demand. Moreover, the operational environment of transmission systems is becoming increasingly rigorous due to continually evolving functions of interconnected power networks from operation jurisdiction to control responsibly – coupled with the rising demand and expectation for reliability.

  • RFID_Applied

    RFID Applied is just that. It’s about the application of RFID. If you want a book about electrical and computer engineering you need another source. Let’s say that you have been asked to lead an effort at your company to use RFID in your supply chain. You have heard about RFID because so much has been written on the topic since Wal-Mart and the US DoD made their proclamations that shippers attach RFID tags to their deliveries. This book is for you!

  • RFID+Essentials

    LIKE SO MANY OTHERS , THIS BOOK WAS WRITTEN BECAUSE WE COULDN ’ T FIND ONE LIKE IT . We needed something to hand to all of those people who have come to us asking for “a good book to read on RFID.” When we looked for candidates we found some great books, but most were aimed at electrical engineers or top-level managers, with very little for those of us who are in between. This book is for developers, system and software architects, and project managers, as well as students and professionals in all of the industries impacted by Radio Frequency Identification (RFID) who want to understand how this technology works. As the title suggests, this book is about RFID in general and not just the most recent developments; however, because so much is going on in the area of RFID for the supply chain and especially the Electronic Product Code (EPC), we have devoted consider- able space to these topics. Regardless of the type of RFID work you may be doing, we think you will find something useful here.

  • RFID+Security

    Radio frequency identification (RFID) is a type of automatic identification systems which has gained popularity in recent years for being fast and reliable in keeping track of the individual objects. In RFID systems, contactless object identification is achieved using radio signals without the need for physical contact as the case with other existing identification technologies such as barcodes. Therefore, a huge number of items can be identified in a short amount of time with high reliability and low cost which makes the RFID technology very attractive for a wide range of applications such as supply chain management, e-health, monitoring humans, pets, animals, and many other objects, toll control, and electrical tagging. Furthermore, RFID technology eliminates the human error and reduces the total cost of the products.

    In the early days, embedded systems were built primarily by engineers in a pretty exclusive club. Embedded devices and software tools were expensive, and building a functional prototype required significant software engineering and electrical engineering experience.
