  • Value+Driven+Product+Planning+and+Systems

    The “bottom-line” metrics of cash flow, demand, price, and return on investment are driven by a second set of financial metrics represented by value to the customer, cost, and the pace of innovation. Get them right relative to competition and impressive bottom-line results should follow. Because of their importance, we call value to the customer, variable cost, and the pace of innovation the “fundamental metrics.”

  • Dynamic Security

    This book is written for engineers involved in the operation, control, and planning of electric power systems. In addition, the book provides information and tools for researchers working in the fields of power system security and stability. The book consists of two volumes. The first volume provides traditional techniques for the stability analysis of large scale power systems. In addition, an overview of the main drivers and requirements for modernization of the traditional methods for online applications are discussed. The second volume provides techniques for online security assessment and corrective action studies. In addition, the impact of variable generation on the security of power systems is considered in the second volume. The first volume may be considered as a background builder while the second volume is intended for the coverage of edge techniques and methods for online dynamic security studies.

  • Electric+Vehicles+on+Power+System

    With the rapid development of electric vehicles (EVs) as well as the promotion and application of vehicle-to-grid (V2G) technologies, EVs charging loads, as flexible loads, have the potential to participate in the grid services, including peak shaving and valley filling, frequency regulation (FR), emergency power, energy market participation, and so on. Therefore, great attention has been paid to EVs and V2G. Focusing on the interactions between EVs and power system, this book aims to bring readers with basic knowledge of electrical engineering promptly to the frontier of the EVs’ influence on power system and environment. This book may serve as a reference for scientists, electrical engineers, and postgraduate students majoring in electrical engineering or other related fields.

  • GaN-on-Si+Displace+Si+and+SiC

    GaN is an already well implanted semiconductor technology, widely diffused in the LED optoelectronics industry. For about 10 years, GaN devices have also been developed for RF wireless applications where they can replace Silicon transistors in some selected systems. That incursion in the RF field has open the door to the power switching capability in the lower frequency range and thus to the power electronic applications. Compared to Silicon, GaN exhibits largely better figures for most of the key specifications: Electric field, energy gap, electron mobility and melting point. Intrinsically, GaN could offer better performance than Silicon in terms of: breakdown voltage, switching frequency and Overall systems efficiency.

  • Chipless_Radio_Frequency_Identification

    Introduction to Radio Frequency Identification (RFID): RFID is a wireless modulation and demodulation technique for automatic identification of objects, tracking goods, smart logistics, and access con- trol. RFID is a contactless, usually short‐distance transmission and reception technique for unique ID data transfer from a tagged object to an interrogator (reader). The generic configuration of an RFID system comprises (i) an ID data‐carrying tag, (ii) a reader, (iii) a middleware, and (iv) an enterprise application.

  • ForDummies_RFID_For_Dummies

    With all the recent hype over radio frequency identification (RFID) and the requirements to implement it, you might think that RFID can turn water into wine, transform lead into gold, and cure the world’s diseases. You might also be worried that RFID will enable Big Brother to track your move- ments to within a foot of your location from a satellite five hundred miles up in space. The truth is, RFID can do none of these things. In this chapter, you find out the basics of what RFID is, what forces are dri- ving RFID as a replacement for the bar code in the marketplace, and what benefits RFID can offer

  • Multiresonator-Based+Chipless+RFID

    Radio frequency identifi cation (RFID) is a modern wireless data transmission and reception technique for applications including automatic identifi cation, asset track- ing and security surveillance. As barcodes and other means of identifi cation and asset tracking are inadequate for recent demands, RFID technology has attracted interest for applications such as logistics, supply chain management, asset tracking and security access control.

  • RFID AND SENSOR NETWORKS Architectures

    Radio frequency identification (RFID) technology is witnessing a recent explosion of development in both industry and academia. A number of applications include supply chain management, electronic payments, RFID passports, environmental monitoring and control, office access control, intelligent labels, target detection and tracking, port management, food production control, animal identification, and so on. RFID is also an indispensable foundation to realize the pervasive computing paradigm—“Internet of things.” It is strongly believed that many more scenarios will be identified when the principles of RFID are thoroughly understood, cheap components available, and when RFID security is guaranteed.

  • RFID_-_A_Guide_to_Radio_Frequency_IDentification

    Radio frequency identifi cation (RFID) technology is a wireless communication technology that enables users to uniquely identify tagged objects or people. RFID is rapidly becoming a cost-effective technology. This is in large part due to the efforts of Wal-Mart and the Department of Defense (DoD) to incorporate RFID technology into their supply chains. In 2003, with the aim of enabling pallet-level tracking of inventory, Wal-Mart issued an RFID mandate requiring its top suppliers to begin tagging pallets and cases, with Electronic Product Code (EPC) labels. The DoD quickly followed suit and issued the same mandate to its top 100 suppliers. This drive to incorporate RFID technology into their supply chains is motivated by the increased ship- ping, receiving and stocking effi ciency and the decreased costs of labor, storage, and product loss that pallet-level visibility of inventory can offer.

  • RFID+and+RFID-Enabled+Sensors

    adio Frequency Identification (RFID) is a rapidly developing automatic wireless data-collection technology with a long history.The first multi-bit functional passive RFID systems,with a range of several meters, appeared in the early 1970s, and continued to evolve through the 1980s. Recently, RFID has experienced a tremendous growth,due to developments in integrated circuits and radios, and due to increased interest from the retail industrial and government.
