Those familiar with mathematics texts will note the fine illustrations throughout and large number of problems offered at the chapter ends. An answer section is provided. Students weary of plodding mathematical prose will find Professor Flanigan's style as refreshing and stimulating as his approach.

The Scandal of Reform pulls the curtain back on New York's reformers past and present, revealing the bonds they have always shared with the bosses they disdain, the policy failures they still refuse to recognize, and the transition they have made from nonpartisan outsiders to ideological insiders.

Francis S. Barry examines the evolution of political reform from the frontlines of New York City's recent reform wars. He offers an insider's account and analysis of the controversial 2003 referendum debate on nonpartisan elections, and he challenges reformersùand members of both partiesùto reconsider their faith in reforms that are no longer serving the public interest.

Author G. N. Watson begins by reviewing various propositions of Poincaré's Analysis Situs, upon which proof of the theorem's most general form depends. Subsequent chapters examine the calculus of residues, calculus optimization, the evaluation of definite integrals, and expansions in series. A historical summary concludes the text, which is supplemented by numerous challenging exercises.

The writing in this book aims to convey the intent of ideas early in discussion. The narrative proceeds through figures, formulas, and text, guiding the reader to do mathematics resourcefully by marshaling the skills of

geometric intuition (the visual cortex being quickly instinctive) algebraic manipulation (symbol-patterns being precise and robust) incisive use of natural language (slogans that encapsulate central ideas enabling a large-scale grasp of the subject).Thinking in these ways renders mathematics coherent, inevitable, and fluid.

The prerequisite is single-variable calculus, including familiarity with the foundational theorems and some experience with proofs.The two-part structure of Applied Complex Variables affords the college instructor maximum classroom flexibility. Once fundamentals are mastered, applications can be studied in any sequence desired. Depending on how many are selected for study, Professor Dettman's impressive text is ideal for either a one- or two-semester course. And, of course, the ambitious student possessing a knowledge of basic calculus will find its straightforward approach rewarding to his independent study efforts.

Applied Complex Variables is a cogent, well-written introduction to an important and exciting branch of advanced mathematics — serving both the theoretical needs of the mathematics specialist and the applied math needs of the physicist and engineer. Students and teachers alike will welcome this timely, moderately priced reissue of a widely respected work.

The two-part approach begins with the development of the primary concept of analytic function, advancing to the Cauchy integral theory, the series development of analytic functions through evaluation of integrals by residues, and some elementary applications of harmonic functions. The second part introduces some of the deeper aspects of complex function theory: mapping properties of analytic functions, applications to various vector field problems with boundary conditions, and a collection of further theoretical results. 1990 edition.

David Casullo's book provides the road map for how to harness your own energy while energizing those around you. Every leader can increase their effectiveness by implementing the ideas he presents.”

--Patrick M. Wright, William J. Conaty GE Professor of Strategic Human Resources in the ILR School (Industrial and Labor Relations), Cornell University

Leaders and managers today are experiencing an “energy crisis” resulting from the failure to engage and inspire their people. Yet, a handful of leaders have found an endless supply of energy to fuel their organizations. They're the ones who attract the top talent, the most loyal customers, and the public's imagination. They're leaders like Zappos's Tony Hsieh and the late Steve Jobs, who've built cultures energized at every level to innovate, grow, and succeed. Leading the High-Energy Culture: What the Best CEOs Do to Create an Atmosphere Where Employees Flourish is the handbook to powering this kind of workplace with the energy that your workforce already possesses.

A change this big starts at the top. David Casullo, a leadership authority and strategic consultant to businesses large and small, explains the steps for establishing an authentic leadership presence based on your powerful personal truths. Then he shares the secrets for how to communicate your vision in order to create a sense of purpose throughout your organization and beyond, thereby spreading excitement to consumers, investors, and the media. Using his own experience, research, and demonstrated results from the leadership development program that he developed while helping transform Raymour & Flanigan from a small regional company to a billion-dollar furniture retail giant, Casullo outlines the specific steps that let you discover and unlock the latent energy in your team.

Casullo organizes these practices into 10 simple principles, each illustrated and reinforced with firsthand client interviews; real-world examples from businesses such as Ford, FedEx, and GE; and thought-provoking interactive exercises. These principles illuminate the path to creating real employee engagement by giving you an actionable model to:

Learn what matters to your organization and its people, and align your leadership strategy with these truths Communicate clearly, with purpose and passion, to create a resonant message Find the leaders in your workforce who give your organization a competitive advantageLeading the High-Energy Culture uses methods proven to generate results. Beyond the bottom line, however, it will reignite your own commitment and passion by giving you a fresh perspective on how to become an energized leader of a charged-up organization.

Prerequisites are minimal; a three-semester course in calculus will suffice to prepare students for discussions of these topics: the complex plane, basic properties of analytic functions (including a rewritten and reorganized discussion of Cauchy's Theorem), analytic functions as mappings, analytic and harmonic functions in applications, and transform methods. Useful appendixes include tables of conformal mappings and Laplace transforms, as well as solutions to odd-numbered exercises.

Students and teachers alike will find this volume, with its well-organized text and clear, concise proofs, an outstanding introduction to the intricacies of complex variables.

The following summer he reports to the Naval Air Training Command in Pensacola, Florida and is greeted by Technical Sergeant Dempsey Flanagan, a Marine more frightening than any non-commissioned officer he has ever seen on the silver screen. From that moment he knows that his life will never be the same.

The days of flight training are occasionally terrifying, often uproarious, and always turbulent. A timid college sophomore who has never succeeded at anything, Tom is increasingly anxious before each flight, and then depressed about his mediocre performance when it is over. On several occasions he barely escapes being washed out for lack of flying aptitude. Though tempted to quit, he decides to hang around and struggle through one disheartening day at a time, always hoping things will improve. Instead of getting better,however, the days get worse. He is hounded by his lack of self-confidence, the disturbing memories of his near-disastrous flying experience eight years earlier, the often expressed doubts of his parents and mentors, and the incessant pleas by his cousin and idol, a WWII fighter pilot, to give up his foolish idea and come home. As he progresses many of his classmates quit or wash out, and a few are killed in aircraft accidents. In the meantime, he must battle the ever-present harassment by an adversary from his youth who is now a fellow cadet. When Tom tries to boost his confidence by participating in reckless rites of passage, the results are usually comical and sometimes painful. He learns that what may seem a good idea over a few beers can prove to be a mistake with long-lasting consequences.

Frustrated by the lack of encouragement from home, Tom joins a group of cadets who surrender their fate to guardian angels, accepting the premise held by many pilots that they are colleagues killed in combat or aircraft accidents. When he finally develops confidence in his flying, his childhood nemesis works hard to tear it down. Tired of dodging the daily attacks, Tom confronts the bigger and stronger cadet in impromptu wrestling and boxing matches and later, in a reckless, illegal dogfight over central Texas that nearly takes both their lives. It is after this frightening experience that their adversarial relationship takes a new and surprising twist.

With graduation day approaching, Tom and his surviving classmates are given their assignments in the fleet. Although disappointed, they struggle to keep a positive attitude and vow to somehow be assigned together at their new duty station where they will strive to make their squadron the finest in the Marine Corps. Later that week, however, an unexplained tragedy torpedoes their renewed enthusiasm. But again, the NavCads’ camaraderie binds them together. They bury their sadness and focus on the adventures awaiting them over the horizon.

With Flying Colors is a must read for all young men and women about to make a major change in their lives. Journeying through Tom Fitzgerald’s calamitous and humorous escapades while in quest of his Navy wings reminds us how people, culture, and events shape us--good or bad--into what we eventually become.

"An extremely useful textbook for both formal classes and for self-study." — Society for Industrial and Applied Mathematics

Engineers often do not have time to take a course in complex variable theory as undergraduates, yet is is one of the most important and useful branches of mathematics, with many applications in engineering. This text is designed to remedy that need by supplying graduate engineering students (especially electrical engineering) with a course in the basic theory of complex variables, which in turn is essential to the understanding of transform theory. Presupposing a good knowledge of calculus, the book deals lucidly and rigorously with important mathematical concepts, striking an ideal balance between purely mathematical treatments that are too general for the engineer, and books of applied engineering which may fail to stress significant mathematical ideas.

The text is divided into two basic parts: The first part (Chapters 1–7) is devoted to the theory of complex variables and begins with an outline of the structure of system analysis and an explanation of basic mathematical and engineering terms. Chapter 2 treats the foundation of the theory of a complex variable, centered around the Cauchy-Riemann equations. The next three chapters — conformal mapping, complex integration, and infinite series — lead up to a particularly important chapter on multivalued functions, explaining the concepts of stability, branch points, and riemann surfaces. Numerous diagrams illustrate the physical applications of the mathematical concepts involved.

The second part (Chapters 8–16) covers Fourier and Laplace transform theory and some of its applications in engineering, beginning with a chapter on real integrals. Three important chapters follow on the Fourier integral, the Laplace integral (one-sided and two-sided) and convolution integrals. After a chapter on additional properties of the Laplace integral, the book ends with four chapters (13–16) on the application of transform theory to the solution of ordinary linear integrodifferential equations with constant coefficients, impulse functions, periodic functions, and the increasingly important Z transform.

Dr. LePage's book is unique in its coverage of an unusually broad range of topics difficult to find in a single volume, while at the same time stressing fundamental concepts, careful attention to details and correct use of terminology. An extensive selection of interesting and valuable problems follows each chapter, and an excellent bibliography recommends further reading. Ideal for home study or as the nucleus of a graduate course, this useful, practical, and popular (8 printings in its hardcover edition) text offers students, engineers, and researchers a careful, thorough grounding in the math essential to many areas of engineering. "An outstanding job." — American Mathematical Monthly
