Power And Performance

Power and Performance: Software Analysis and Optimization is a guide to solving performance problems in modern Linux systems. Power-efficient chips are no help if the software those chips run on is inefficient. Starting with the necessary architectural background as a foundation, the book demonstrates the proper usage of performance analysis tools in order to pinpoint the cause of performance problems, and includes best practices for handling common performance issues those tools identify. Provides expert perspective from a key member of Intel’s optimization team on how processors and memory systems influence performance Presents ideas to improve architectures running mobile, desktop, or enterprise platforms Demonstrates best practices for designing experiments and benchmarking throughout the software lifecycle Explains the importance of profiling and measurement to determine the source of performance issues

To perform well in today's highly competitive world where technical skills have been advanced to an unprecedented degree, a singer must be able to handle incredible pressure within the performing arena; his or her ability to deal with this stress will often determine whether he or she will succeed. Why, then, do singers with less technical skill sometimes out-perform stars? Why do some stars suddenly stop performing? What is that mysterious factor that makes an electric performance? Consistent, competent performances do not depend solely upon superior vocal skills, nor are they a matter of luck. On the contrary, the best performances result from a combination of mental attitude, concrete performing skills, and excellent technical skills in that order. Yet most singers have never had the opportunity to acquire the essential skills that make for a successful career. Written as a self-help manual for singers at all levels of expertise, Power Performance for Singers is designed to teach performing artists, and especially singers, how to experience elite performance at their level. The skills outlined in this book will help singers use what they have, to enjoy their voices during performance, and to perform consistently to the best of their present ability.

Recently in the field of theatre studies there has been an increasing amount of debate and dissonance regarding the borders of its territory, its methodologies, subject matter, and scholarly perspectives. The nature of this debate could be termed "political" and, in fact, concerns "the performance of power"—the struggle over power relations embedded in texts, methodologies, and the academy itself. This striking new collection of nineteen divergent essays represents this performance of power and the way in which the recent convergence of new critical theories with historical studies has politicized the study of the theatre. Neither play text, performance, nor scholarship and teaching can safely reside any longer in the "free," politically neutral, self-signifying realm of the aesthetic. Politicizing theatrical discourse means that both the hermeneutics and the histories of theatre reveal the role of ideology and power dynamics. New strategies and concepts—and a vital new phase of awareness—appear in these illuminating essays. A variety of historical periods, from the Renaissance through the Victorian and up to the most contemporary work of the Wooster group, illustrate the ways in which contemporary strategies do not require contemporary texts and performances but can combine with historical methods and subjects to produce new theatrical discourse.

Performativity has emerged as a critical new idea across the humanities and social sciences, from literary and cultural studies to the study of gender and the philosophy of action. In this volume, Jeffrey Alexander demonstrates how performance can reorient our study of politics and society. Alexander develops a cultural pragmatics that shifts cultural sociology from texts to gestural meanings. Positioning social performance between ritual and strategy, he lays out the elements of social performance - from scripts to mise-en-scène, from critical mediation to audience reception - and systematically describes their tense interrelation. This is followed by a series of empirically oriented studies that demonstrate how cultural pragmatics transforms our approach to power. Alexander brings his new theory of social performance to bear on case studies that range from political to cultural power: Barack Obama's electoral campaign, American failure in the Iraqi war, the triumph of the Civil Rights Movement, terrorist violence on September 11th, public intellectuals, material icons, and social science itself. This path-breaking work by one of the world's leading social theorists will command a wide interdisciplinary readership.

Shows how global ratings and rankings shape political agendas and influence states' behavior, reframing how we think about power.

Power Plant Performance discusses the different procedures and practices involved in the operation of power plants. The book is divided into four parts. Part I covers general considerations such as steam cycles; the sampling, analysis, and assessment of coal; and pumping – its related terms, the different types of pumps, and the determination of sizes and efficiency. Part II tackles the important measurements in power plants such as temperature, pressure, and gas and water flow. Part III deals with the operation of power plant components such as the boiler, turbine, and condensers. Part IV tackles other related topics such as steam turbine heat consumption tests; plant-operating parameters; and the costs of outages. The text is recommended for professionals involved in the development, maintenance, and operation of power plants, especially those who would like to be familiar with the basics.
