Information Security/Java “This book is mandatory reading for every user and developer of Webware.” -Peter G. Neumann, Moderator of the Risks Forum, from his review of the first edition Securing Java Java security is more important now than ever before. As Java matures and moves into the enterprise, security takes a more prominent role. But as Java evolves, its security issues and architectures get more complicated. Written by the world’s leading experts on mobile code security, this updated and expanded edition of the groundbreaking guide to Java security includes lessons for Web users, developers, system administrators, and business decision-makers alike. This book navigates the uncharted waters of mobile code security and arms the reader with the knowledge required for securing Java. It provides in-depth coverage of:
* The base Java security sandbox, made up of the Verifier, Class Loaders, and the Security Manager
* Code signing, stack inspection, and the new Java 2 security architecture

Real-Time Applications with Stochastic Task Execution Times: Analysis and Optimisation

Real-Time Applications with Stochastic Task Execution Times: Analysis and Optimisation

Real-Time Applications with Stochastic Task Execution Times: Analysis and Optimisation
Springer; 1 edition | ISBN: 1402055056 | 160 pages | January 2007 | PDF | 1 Mb

Embedded systems have become indispensable in our lives: household appliances, cars, airplanes, power plant control systems, medical equipment, telecommunication systems, space technology, they all contain digital computing systems with dedicated functionality. Most of them, if not all, are real-time systems, i.e. their responses to stimuli have timeliness constraints.
The timeliness requirement has to be met despite some unpredictable, stochastic behaviour of the system. In this book, we address one cause of such stochastic behaviour, namely the application and platform-dependent stochastic task execution times.

The problem of accurately determining the deadline miss ratio of an application and to optimise the performance of a system taking the aforementioned ratio into consideration is extremely important as it has a significant impact on the cost of the end product.

Real-Time Applications with Stochastic Task Execution Times presents three approaches to the analysis of the deadline miss ratio of applications with stochastic task execution times. Each of the three approaches fits best to a different context. The first approach is an exact one and is efficiently applicable to monoprocessor systems. The second approach is an approximate one, which allows for designer-controlled trade-off between analysis accuracy and analysis speed. It is efficiently applicable to multiprocessor systems. The third approach is less accurate but sufficiently fast in order to be placed inside optimisation loops. Based on the last approach, we propose a heuristic for task mapping and priority assignment for deadline miss ratio minimisation.

PHP : PHP Web 2.0 Mashup Projects

PHP Web 2.0 Mashup Projects

Shu-Wai Chow “PHP Web 2.0 Mashup Projects”
Packt Publishing | 2007-09-22 | ISBN: 184719088X | 304 pages | PDF | 7,1 Mb

This practical tutorial has detailed, carefully explained case studies using PHP to build new, effective mashup applications, which combine data from multiple external online sources into an integrated Web 2.0 experience. If you are confident with PHP programming and interested in mashing things up, this book is for you! All you need to know about formats, protocols, web services, and web APIs is covered as you learn to write PHP code to remotely consume services like Google Maps, Flickr, Amazon, YouTube, MSN Search, Yahoo!, Last.fm, the Internet UPC Database, and even the California Highway Patrol Traffic data! The 5 real-world PHP projects each start with an overview of technologies and protocols needed and then dive into the tools used and details of creating the project, and you can download each project’s source code. You will learn how these technologies work with each other and how to use this information, together with your imagination, to build your own cutting-edge websites.

Introduction to Probability with Statistical Applications

Publisher: Birkh?user Boston
Language: English
ISBN: 0817644970
Paperback: 328 pages
Data: Aug 2007
Format: PDF
Description: This textbook is an introduction to probability and statistics for non-mathematics majors who do not need the exhaustive detail and mathematical depth provided in more comprehensive treatments of the subject. The presentation covers the mathematical laws of random phenomena, including discrete and continuous random variables, expectation and variance, and common probability distributions such as the binomial, Poisson, and normal distributions. Main statistical concepts considered are point and interval estimates, hypothesis testing, power function, various statistical tests: z, t, chi-square and Kolmogorov-Smirnov.

Key features:
* Presents rigorous discussion, with definitions, theorems, and proofs, but aimed at a non-specialist audience;
*Avoids linear algebra;
* Treats informally the few unavoidable concepts from multivariable calculus, such as double integrals;
* Motivates new concepts throughout using examples and brief conceptual discussions;
* Develops basic ideas with clear definitions, carefully designed notation and techniques of statistical analysis, along with well-chosen examples, exercises and applications.

The book contains enough material for two semesters but, with judicious selection, it can also be used for a one-semester course, either in probability and statistics or in probability alone. .Advanced undergraduate and graduate students in computer science, engineering, and other natural and social sciences with only a basic background in calculus will benefit from this introductory text balancing theory with applications.
Thanks, procyon!

Classification Algorithms for Codes and Designs

Publisher: Springer
Language: English
ISBN: 3540289909
Paperback: 413 pages
Data: 2005
Format: PDF
Description: This book considers one of the basic problems in discrete mathematics: given a collection of constraints, describe up to isomorphism all the objects that meet them. Only a handful of classification results for combinatorial objects are dated before the mid-20th century; indeed, it is through modern computers and recent developments in algorithms that this topic has flourished and matured. This book is the first comprehensive reference on combinatorial classification algorithms, with emphasis on both the general theory and application to central families of combinatorial objects, in particular, codes and designs. The accompanying DVD provides an exhaustive catalogue of combinatorial objects with small parameters. The book will be of great interest to researchers and can be used as course material for graduate courses in both computer science and mathematics.

Stochastic Calculus and Financial Applications

Publisher: Springer
Language: English
ISBN: 0387950168
Paperback: 344 pages
Data: Jun 2003
Format: PDF
Description: The Wharton School course on which the book is based is designed for energetic students who have had some experience with probability and statistics, but who have not had advanced courses in stochastic processes. Even though the course assumes only a modest background, it moves quickly and – in the end – students can expect to have the tools that are deep enough and rich enough to be relied upon throughout their professional careers. The course begins with simple random walk and the analysis of gambling games. This material is used to motivate the theory of martingales, and, after reaching a decent level of confidence with discrete processes, the course takes up the more demanding development of continuous time stochastic process, especially Brownian motion. The construction of Brownian motion is given in detail, and enough material on the subtle properties of Brownian paths is developed so that the student should sense of when intuition can be trusted and when it cannot. The course then takes up the It¿ integral and aims to provide a development that is honest and complete without being pedantic. With the It¿ integral in hand, the course focuses more on models. Stochastic processes of importance in Finance and Economics are developed in concert with the tools of stochastic calculus that are needed in order to solve problems of practical importance. The financial notion of replication is developed, and the Black-Scholes PDE is derived by three different methods. The course then introduces enough of the theory of the diffusion equation to be able to solve the Black-Scholes PDE and prove the uniqueness of the solution.
