S is a high-level language for manipulating, analysing and displaying data. It forms the basis of two highly acclaimed and widely used data analysis software systems, the commercial S-PLUS® and the Open Source R. This book provides an in-depth guide to writing software in the S language under either or both of those systems. It is intended for readers who have some acquaintance with the S language and want to know how to use it more effectively, for example to build re-usable tools for streamlining routine data analysis or to implement new statistical methods. One of the outstanding strengths of the S language is the ease with which it can be extended by users. S is a functional language, and functions written by users are first-class objects treated in the same way as functions provided by the system. S code is eminently readable and so a good way to document precisely what algorithms were used, and as much of the implementations are themselves written in S, they can be studied as models and to understand their subtleties. The current implementations also provide easy ways for S functions to call compiled code written in C, Fortran and similar languages; this is documented here in depth. Increasingly S is being used for statistical or graphical analysis within larger software systems or for whole vertical-market applications. The interface facilities are most developed on Windows® and these are covered with worked examples. The authors have written the widely used Modern Applied Statistics with S-PLUS, now in its third edition, and several software libraries that enhance S-PLUS and R; these and the examples used in both books are available on the Internet. Dr. W.N. Venables is a senior Statistician with the CSIRO/CMIS Environmetrics Project in Australia, having been at the Department of Statistics, University of Adelaide for many years previously. Professor B.D. Ripley holds the Chair of Applied Statistics at the University of Oxford, and is the author of four other books on spatial statistics, simulation, pattern recognition and neural networks. Both authors are known and respected throughout the international S and R communities, for their books, workshops, short courses, freely available software and through their extensive contributions to the S-news and R mailing lists.

Here is a thorough and authoritative guide to the latest version of the S language and to its programming environment the premier software platform for computing with data. Programming with Data describes a new and greatly extended version of S and is written by the chief designer of the language. The book is a guide to the complete programming process, starting from simple interactive use and continuing through ambitious software projects. S is designed for computing with data-for any project in which organizing, visualizing, summarizing, or modeling data are central concerns. Its focus is on the needs of the programmer/user, and its goal is "to turn ideas into software, quickly and faithfully." S is a functional object-based language with a huge library of functions for all aspects of computing with data. Its long and enthusiastic use in statistics and applied fields has also led to many valuable libraries of user-written functions. The new version of S provides powerful class/method structure, new techniques to deal with large objects, extended interfaces to other languages and files, object-based documentation compatible with HTML, and powerful new interactive programming techniques. This version of S underlies the S-PLUS system, versions 5*0 and higher.

Annotation Adobes Stage3D (Molehill) is a set of 3D APIs that has brought 3D to the Flash platform. Being a completely new technology, there were almost no resources to get you acquainted with this revolutionary platform, until now. This book will show you how to make your very own next-gen 3D games in Flash. If you have ever dreamed of writing your own console-style 3d game in Flash, get ready to be blown away by the hardware accelerated power of Stage3D. This book will lead you step-by-step through the process of programming a 3D game in Actionscript 3 using this exciting new technology. Filled with examples, pictures and source code, this is a practical and fun-to-read guide that will benefit both 3D programming beginners and expert game developers alike. Starting with simple tasks like setting up Flash to render a simple 3d shape, each chapter presents a deeper and more complete videogame as an example project. Right from a simple tech demo, your game will grow to become a finished product - your very own playable 3d game filled with animation, special effects, sounds, and tons of action. The goal of this book is to teach you how to program a complete game in Molehill that has a beginning, middle, and game over. As you progress further into your epic quest, you will learn all sorts of useful tricks such as ways to create eye-catching special effects using textures, special blend modes for transparent particle systems, fantastic vertex and fragment programs that are used to craft beautiful shaders and much more. You will learn how to upload the geometry of your 3D models to video RAM for ultra-fast rendering. You will dive into the magical art of AGAL shader programming. You will learn optimization tricks to achieve blazingly fast frame rate even at full screen resolutions. With each chapter, you will level up your game programming skills, earning the title of Molehill Master you will be able to honestly call yourself a 3D game programmer. This book is written for beginners by a veteran game developer. It will become your trusty companion filled with the knowledge you need to make your very own 3D games in Flash.

This book constitutes the refereed proceedings of the 17th European Symposium on Programming, ESOP 2008, held in Budapest, Hungary, in March/April 2008, as part of ETAPS 2008, the European Joint Conferences on Theory and Practice of Software. The 25 revised full papers presented together with the abstract of one invited talk and two tool presentations were carefully reviewed and selected from 104 submissions and address fundamental issues in the specification, analysis, and implementation of programming languages and sytems. The papers are organized in topical sections on static analysis, security, concurrency and program verification.

The primary aim of this monograph is to present the current research efforts that have gone into/or going on in the systematic design of real-time programs. Such an effort would help researchers and users in the area to get a clear picture of the issues of specification, verification and design of real-time reactive programs. It will clearly enable us to identify languages that can be used for different kinds of applications. Obviously, in an upcoming area like this, this presentation is far from complete. The quintessence of the monograph can be captured by the following question: How can we design and develop Robust Reactive (real-time) Programs? We address this question in this monograph through the various underlying issues listed, such as characteristics of real-time/reactive programs, reactive programming languages, verification and refinements.

Fractional Programming

Mathematical programming has know a spectacular diversification in the last few decades. This process has happened both at the level of mathematical research and at the level of the applications generated by the solution methods that were created. To write a monograph dedicated to a certain domain of mathematical programming is, under such circumstances,especially difficult. In the present monograph we opt for the domain of fractional programming. Interest of this subject was generated by the fact that various optimization problems from engineering and economics consider the minimization of a ratio between physical and/or economical functions, for example cost/time, cost/volume,cost/profit, or other quantities that measure the efficiency of a system. For example, the productivity of industrial systems, defined as the ratio between the realized services in a system within a given period of time and the utilized resources, is used as one of the best indicators of the quality of their operation. Such problems, where the objective function appears as a ratio of functions, constitute fractional programming problem. Due to its importance in modeling various decision processes in management science, operational research, and economics, and also due to its frequent appearance in other problems that are not necessarily economical, such as information theory, numerical analysis, stochastic programming, decomposition algorithms for large linear systems, etc., the fractional programming method has received particular attention in the last three decades.
