Communication Networking: An Analytical Approach by Kumar

Key Features Systematically uses mathematical models and analyses to drive the development of a practical understanding of core network engineering problems. Provides in-depth coverage of many current topics, including network calculus with deterministically-constrained traffic, congestion control for elastic traffic, packet switch queuing, switching architectures, virtual path routing, and routing for quality of service. Includes over 200 hands-on exercises and class-tested problems, dozens of schematic figures, a review of key mathematical concepts, and a glossary. Description The viewpoint is that communication networking is about efficient resource sharing. The focus is on the three building blocks of communication networking, namely, multiplexing, switching and routing. The approach is analytical, with the discussion being driven by mathematical analyses of and solutions to specific engineering problems. The result? A comprehensive, effectively organized treatment of core engineering issues in communication networking. Written for both the networking professional and for the classroom, this book covers fundamental concepts in detail and places design issues in context by drawing on real world examples from current technologies. Readership PROFESSIONAL REFERENCE: Networking professionals whose work is primarily architecture definition and implementation, i.e., network engineers and designers at telecom companies, industrial research labs, etc. ACADEMIC: Final year undergrad and first year graduate students in EE, CE, and CS programs. Quotes This book combines an innovative and uniform representation of a variety of communication networks, simple to understand motivations for real design problems for these networks, intuitive approaches to solutions, and rigorous mathematical analysis where appropriate. It will be very valuable both as a textbook and as a reference for practitioners. --Bharat Doshi, Director of Transformational Communication, Johns Hopkins. ...

Chemistry: A Very Short Introduction by Peter Atkins

Library

Most people remember chemistry from their schooldays as largely incomprehensible, a subject that was fact-rich but understanding-poor, smelly, and so far removed from the real world of events and pleasures that there seemed little point, except for the most introverted, in coming to terms with its grubby concepts, spells, recipes, and rules. Peter Atkins wants to change all that.In this Very Short Introduction to Chemistry, he encourages us to look at chemistry anew, through a chemist's eyes, in order to understand its central concepts and to see how it contributes not only towards our material comfort, but also to human culture. Atkins shows how chemistry provides the infrastructure of our world, through the chemical industry, the fuels of heating, power generation, and transport, as well as the fabrics of our clothing and furnishings.By considering the remarkable achievements that chemistry has made, and examining its place between both physics and biology, Atkins presents a fascinating, clear, and rigorous exploration of the world of chemistry - its structure, core concepts, and exciting contributions to new cutting-edge technologies. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable....

Developing User Interfaces by Dan R. Olsen

Library

In the early days of computing, technicians in white coats controlled refrigerator-sized computers housed in sealed rooms, far from ordinary users. Today, computers are inexpensive commodities, like television sets,and ordinary people control and interact with them. This new paradigm has led to a burgeoning demand for graphics-intensive and highly interactive interfaces.Developing User Interfaces is targeted at the programmer who will actually implement, rather than design, the user interface. Most user interface books focus on psychology and usability, not programming techniques. This book recognizes the need for programmers to collaborate with usability experts and psychologists, so topics such as the principles of visualization, human perception, and usability evaluation are touched upon. Yet the primary focus remains on those tools and techniques required for programming the complex user interface. * Focuses on advanced programming topics * event handling * interaction with geometric objects * widget tool kits * input syntax * Useful to programmers using any language―no particular windowing system or tool kit is presumed, examples are drawn from a variety of commercial systems, and code examples are presented in pseudo code * The basic concepts of traditional computer graphics such as drawing and three-dimensional modeling are covered for readers without a computer graphics background....

Exercises in Programming Style by Cristina Videira Lopes

Library

Using a simple computational task (term frequency) to illustrate different programming styles, Exercises in Programming Style helps readers understand the various ways of writing programs and designing systems. It is designed to be used in conjunction with code provided on an online repository. The book complements and explains the raw code in a way that is accessible to anyone who regularly practices the art of programming. The book can also be used in advanced programming courses in computer science and software engineering programs.The book contains 33 different styles for writing the term frequency task. The styles are grouped into nine categories: historical, basic, function composition, objects and object interactions, reflection and metaprogramming, adversity, data-centric, concurrency, and interactivity. The author verbalizes the constraints in each style and explains the example programs. Each chapter first presents the constraints of the style, next shows an example program, and then gives a detailed explanation of the code. Most chapters also have sections focusing on the use of the style in systems design as well as sections describing the historical context in which the programming style emerged....
