Available in PDF, EPUB and Kindle. Book excerpt: Improve Failure Detection and Optimize Protection In the ever-evolving field of protective relay technology, an engineer’s personal preference and professional judgment are as important to power system protection as the physical relays used to detect and isolate abnormal conditions. Invaluable Insights from an Experienced Expert Protective Relay Principles focuses on probable power system failure modes and the important characteristics of the protective relays used to detect these postulated failures. The book presents useful new concepts in a way that is easier to understand because they are equally relevant to older, electromechanical and solid-state relays, and newer, more versatile microprocessor-based relays. It introduces the applications, considerations, and setting philosophies used in transmission-line, distribution-line, and substation applications, covering concepts associated with general system operations and fault detection. Topics include relay load limits, cold load pickup, voltage recovery, and arc flash. The author also delves into the philosophies that engineers employ in both urban and rural areas, with a detailed consideration of setpoint function. Analysis of Key Concepts That Are Usually Just Glossed Over This versatile text is ideal for new engineers to use as a tutorial before they open the instruction manuals that accompany multi-function microprocessor-based relays. Guiding readers through the transient loading conditions that can result in relay misoperation, the author elaborates on concepts that are not generally discussed, but can be very helpful in specific applications. Readers will come away with an excellent grasp of important design considerations for working with overcurrent, over- and undervoltage, impedance, distance, and differential type relay functions, either individually or in combination. Also useful for students as a textbook, this book includes practical examples for many applications, and offers guidance for more unusual ones.

Book excerpt: This book examines how one aspect of the social and technological situation of literature--namely, the postal system--determined how literature was produced and what was produced within literature. Language itself has the structure of a relay, where what is transmitted depends on a prior withholding. The social arrangements and technologies for achieving this transmission thus have had a particularly powerful impact on the imagination of literature as a medium. The book has three parts. The first part reconstructs the postal conditions of classic and Romantic literature: the invention of postage in the seventeenth century, which transformed the postal system into a service meant to be used by the population (instead of by the prince alone); the sexualization of letter writing, which was introduced in the middle of the eighteenth century and changed the reading of a letter into an interpretation of intimate confessions of the soul; and Goethes turning of this new ontology of the letter into a logistics of literature whereby literary authorship was constructed by means of postal logistics, with the precision of engineering. The second part analyzes nineteenth-century postal innovations that facilitated communication through letters and examines how literary works were able to live off such communication. These innovations included the reform of the post office; the invention of the postage stamp; the Universal Postal Union, which subjected letter writing to an economy of materials and uniform standards; and the telegraph and the telephone, which surpassed literature in terms of speed, economy, and analog-signal processing. In the third part, on the basis of a close reading of Franz Kafkas letters to his typist-fiancée, the author demonstrates how postal logistics of love and authorship have worked in the era of modern postal systems and technical media. Kafkas correspondence is deciphered as a "war of nerves waged by means of all available techniques and conditions of transmission.

Book excerpt: The Bible is laden with stories of those who've carried the baton before us, who've stumbled,who've persevered. It's equally laden with stories of God's chosen people falling-away from theirfaith - often in the space of just a few short years.So is Christianity itself in peril? "Of course not," Shamblin notes, "but under the rightcircumstances, it is endangered in any given region of the world. Consider that, just a generationand a half after John Lennon outraged the West by quipping that the Beatles were 'bigger thanJesus,' Europe's percentage of practicing Christians is in the single digits."In The Relay, Shamblin catalogs the comparative successes and failures of nine individuals inpassing-along their faith to the next generations - from the father of all failure (Adam) to theultimate Spirtual Rags To Riches success (Paul). At the center of his book, not only thematicallybut literally (chapter six of eleven) is Jesus Christ, whose followers who took "the race" to a wholenew level, and a whole new arena.While a relay makes for an apt metaphor for passing-along our faith, Shamblin concludes, ourgoal as Christians is not to win a race, but to win the world. More than a message of profoundaffirmation, The Relay is a triumph of practical How To advice for anyone looking to take theirown journey with the Lord to the next level - and beyond.

Available in PDF, EPUB and Kindle. Book excerpt: CMOS scaling has been very successful in generating small, fast, low cost electronics. However, in advanced CMOS nodes, the total power consumption is dominated by the static power dissipation, which is caused greatly by gate leakage, short channel effects, and finite subthreshold slope. Further scaling of CMOS only exacerbates these problems. Nanoelectromechanical (NEM) relays are promising devices for assisting CMOS systems by reducing the static power dissipation due to their zero leakage current, infinite subthreshold slope, and scalable actuation voltage. Electrostatically-actuated NEM relays are devices where the operation is based on the deformation of a flexible beam under the influence of electrostatic force in order to create a conducting path between two electrodes. This work studies the fabrication process development of sidewall-coated laterally-actuated NEM relays. The developed process enables decoupling of the mechanical and electrical properties of the relay, allowing independent optimization of each property and paving the path for creating a back-end-of-line (BEOL) compatible process. Furthermore, a major failure mechanism of NEM relays is beam-to-gate shorting after actuation. To ameliorate this problem, new designs with improved mechanical properties were simulated and tested. These designs utilize a stiff electrode and a compliant beam to eliminate undesired beam deformation near the gate electrode. These results in addition to variation studies, stress outcomes, and basic logic functionality of the NEM relays are shown.
