• Sommario/riassunto: Tackling the questions that systems designers care about, this book brings queueing theory decisively back to computer science. The book is written with computer scientists and engineers in mind and is full of examples from computer systems, as well as manufacturing and operations research. Fun and readable, the book is highly approachable, even for undergraduates, while still being thoroughly rigorous and also covering a much wider span of topics than many queueing books. Readers benefit from a lively mix of motivation and intuition, with illustrations, examples and more than 300 exercises - all while acquiring the skills needed to model, analyze and design large-scale systems with good performance and low cost. The exercises are an important feature, teaching research-level counterintuitive lessons in the design of computer systems. The goal is to train readers not only to customize existing analyses but also to invent their own.

• Sommario/riassunto: Offering a new, exciting approach to the typically conventional practice for creating presentations, this new edition to a popular resource has compiled its material from more than 200 research studies in the fields of communication, marketing, psychology, multimedia, and law. The book demonstrates how to adapt a presentation to different audience personality preferences, what role the data should play and how much of it is necessary, how to turn data into a story, and how to design persuasive-yet-comprehensible visual layouts.
