Elementary Functions: Algorithms and Implementation
by Jean-Michel MullerThis textbook presents the concepts and tools necessary to understand, build, and implement algorithms for computing elementary functions (e.g., logarithms, exponentials, and the trigonometric functions). Both hardware- and software-oriented algorithms are included, along with issues related to accurate floating-point implementation. This third edition has been updated and expanded to incorporate the most recent advances in the field, new elementary function algorithms, and function software.After a preliminary chapter that briefly introduces some fundamental concepts of computer arithmetic, such as floating-point arithmetic and redundant number systems, the text is divided into three main parts. Part I considers the computation of elementary functions using algorithms based on polynomial or rational approximations and using table-based methods; the final chapter in this section deals with basic principles of multiple-precision arithmetic. Part II is devoted to a presentation of “shift-and-add” algorithms (hardware-oriented algorithms that use additions and shifts only). Issues related to accuracy, including range reduction, preservation of monotonicity, and correct rounding, as well as some examples of implementation are explored in Part III. Numerous examples of command lines and full programs are provided throughout for various software packages, including Maple, Sollya, and Gappa. New to this edition are an in-depth overview of the IEEE-754-2008 standard for floating-point arithmetic; a section on using double- and triple-word numbers; a presentation of new tools for designing accurate function software; and a section on the Toom-Cook family of multiplication algorithms.The techniques presented in this book will be of interest to implementers of elementary function libraries or circuits and programmers of numerical applications. Additionally, graduate and advanced undergraduate students, professionals, and researchers in scientific computing, numerical analysis, software engineering, and computer engineering will find this a useful reference and resource.PRAISE FOR PREVIOUS EDITIONS“[T]his book seems like an essential reference for the experts (which I'm not). More importantly, this is an interesting book for the curious (which I am). In this case, you'll probably learn many interesting things from this book. If you teach numerical analysis or approximation theory, then this book will give you some good examples to discuss in class." — MAA Reviews (Review of Second Edition)"The rich content of ideas sketched or presented in some detail in this book is supplemented by a list of over three hundred references, most of them of 1980 or more recent. The book also contains some relevant typical programs." — Zentralblatt MATH (Review of Second Edition)“I think that the book will be very valuable to students both in numerical analysis and in computer science. I found [it to be] well written and containing much interesting material, most of the time disseminated in specialized papers published in specialized journals difficult to find." — Numerical Algorithms (Review of First Edition)

Elementary Mathematical and Computational Tools for Electrical and Computer Engineers Using MATLAB
by Jamal T. ManassahEngineers around the world depend on MATLAB for its power, usability, and outstanding graphics capabilities. Yet too often, engineering students are either left on their own to acquire the background they need to use MATLAB, or they must learn the program concurrently within an advanced course. Both of these options delay students from solving realistic design problems, especially when they do not have a text focused on applications relevant to their field and written at the appropriate level of mathematics.Ideal for use as a short-course textbook and for self-study Elementary Mathematical and Computational Tools for Electrical and Computer Engineers Using MATLAB fills that gap. Accessible after just one semester of calculus, it introduces the many practical analytical and numerical tools that are essential to success both in future studies and in professional life. Sharply focused on the needs of the electrical and computer engineering communities, the text provides a wealth of relevant exercises and design problems. Changes in MATLAB's version 6.0 are included in a special addendum.The lack of skills in fundamental quantitative tools can seriously impede progress in one's engineering studies or career. By working through this text, either in a lecture/lab environment or by themselves, readers will not only begin mastering MATLAB, but they will also hone their analytical and computational skills to a level that will help them to enjoy and succeed in subsequent electrical and computer engineering pursuits.

Elementary Number Theory, Cryptography and Codes (Universitext)
by M. Welleda Baldoni Ciro Ciliberto G.M. Piacentini CattaneoIn this volume one finds basic techniques from algebra and number theory (e.g. congruences, unique factorization domains, finite fields, quadratic residues, primality tests, continued fractions, etc.) which in recent years have proven to be extremely useful for applications to cryptography and coding theory. Both cryptography and codes have crucial applications in our daily lives, and they are described here, while the complexity problems that arise in implementing the related numerical algorithms are also taken into due account. Cryptography has been developed in great detail, both in its classical and more recent aspects. In particular public key cryptography is extensively discussed, the use of algebraic geometry, specifically of elliptic curves over finite fields, is illustrated, and a final chapter is devoted to quantum cryptography, which is the new frontier of the field. Coding theory is not discussed in full; however a chapter, sufficient for a good introduction to the subject, has been devoted to linear codes. Each chapter ends with several complements and with an extensive list of exercises, the solutions to most of which are included in the last chapter. Though the book contains advanced material, such as cryptography on elliptic curves, Goppa codes using algebraic curves over finite fields, and the recent AKS polynomial primality test, the authors' objective has been to keep the exposition as self-contained and elementary as possible. Therefore the book will be useful to students and researchers, both in theoretical (e.g. mathematicians) and in applied sciences (e.g. physicists, engineers, computer scientists, etc.) seeking a friendly introduction to the important subjects treated here. The book will also be useful for teachers who intend to give courses on these topics.

Elementi di informatica in diagnostica per immagini (Imaging & Formazione #1)
by Roberto Grassi Giuseppe Guglielmi Giovanni Pinto Alfredo SianiIl volume nasce dall’esperienza acquisita dagli autori con le lezioni svolte nel corso di laurea in Tecniche Radiologiche per Immagini e Radioterapia. I contenuti sono articolati in quattro parti principali - il Sistema e l’Hardware, il Software, Macchine Evolute, Pratica e Applicazioni - e i singoli capitoli sono arricchiti da curiosità e approfondimenti allo scopo di sollecitare l’attenzione del lettore a fini didattici. Con la stessa finalità nel testo si alternano concetti formativi, specialistici e squisitamente professionali, come le reti neurali, a richiami storici sulla evoluzione dei sistemi di calcolo. Stile e linguaggio sono spesso volutamente orientati alla rapida comprensione e facile assimilazione di argomenti anche complessi, più che al rigore strettamente formale. Il lettore potrà infine valutare il proprio grado di apprendimento eseguendo i test di autoverifica strutturati con il metodo "multiple choice". Il volume rappresenta pertanto un efficace strumento educativo per i tecnici di radiologia medica come pure un utile riferimento per gli operatori che usino quotidianamente procedure informatiche nelle strutture sanitarie presso le quali svolgono la loro professione.
Elements for a Theory of Decision in Uncertainty (Applied Optimization #32)
by Jaime Gil-AlujaDecisions in uncertainty Scientific reaction to change During latter decades, the basic elements that have traditionally made up the society in wh ich economic activity develops, have been submitted to the effect of multiple aggressions as a consequence of the outcome of events motivated by the nature itself of the human being, always seeking a level of happiness that is never reached. In a very brief manner we are accustomed to mention these by using words such as revolution, profound changes, convulsions . . . . , the results of which are manifest through non-linear reactions that lead to a future charged with uncertainty. To get to know, explain and treat this new world constitutes one of the many objectives of those who desire a society in the service of man, and for those who aspire to the fact of the concept of mutuality transcending the use less limits of the printed word. But for this it will be necessary to overcome a whole realm of obstacles placed in the way by those comfortably embedded in old principles, decrepit ideas and are not willing to open the windows of their mind to receive the fresh air of a new era.

Elements of C (Foundations of Computer Science)
by Morton H. LewinStatements in C, like statements in any other programming language, consist almost entirely of expressions and special reserved words. Declarations in C, unlike declarations in other languages, also contain arbitrary expressions. Thus, studying the means by which C expressions are constructed and evaluated is especially important-particularly since the number of permissible C operators is so large. Since all of the operands in a C expression (excluding constants) must be properly declared before they are used, and since declarations themselves contain expressions, the teaching of C involves the following chicken-and-egg problem: Should one begin by considering only elementary declarations, in which case the topic of expression construction and evaluation cannot be fully treated in one place, because the operators that pertain to the more complex objects-like pointers and structures (whose declarations have not yet been introduced)--have not yet been covered, or should one postpone entirely the issue of how decla rations are written (merely assuming that all of the objects under discussion have been properly declared) in order to fully treat all types of operands and operators in one comprehensive discussion? If the student is encouraged to begin writing programs immediately, the former choice is mandatory, because even the most elementary programs must vII Preface viii contain proper declarations. Thus, most C textbooks postpone the discussion of objects like arrays, structures, and pointers (and of the operators that pertain to them) until the second half of the book is reached.
Elements of Cloud Computing Security: A Survey of Key Practicalities (SpringerBriefs in Computer Science)
by Mohammed M. AlaniThis book offers a thorough yet easy-to-read reference guide to various aspects of cloud computing security. It begins with an introduction to the general concepts of cloud computing, followed by a discussion of security aspects that examines how cloud security differs from conventional information security and reviews cloud-specific classes of threats and attacks. A range of varying threats in cloud computing are covered, from threats of data loss and data breaches, to threats to availability and threats posed by malicious insiders. Further, the book discusses attacks launched on different levels, including attacks on the hypervisor, and on the confidentiality of data. Newer types, such as side-channel attacks and resource-freeing attacks, are also described. The work closes by providing a set of general security recommendations for the cloud.
Elements of Cloud Storage Security: Concepts, Designs and Optimized Practices (SpringerBriefs in Computer Science)
by Tatiana Galibus Viktor V. Krasnoproshin Robson de Oliveira Albuquerque Edison Pignaton de FreitasThis work provides guidelines for the practical implementation of security architecture in a particular corporate cloud. The authors are mathematicians and specialists in data modeling and security. Experience of scientific collaboration with industry inspired the authors to attempt to conceptualize the common processes and strategies in cloud security, in order to make security system deployment as simple and transparent as possible. The deployment is broken into several essential steps that allow the functionality of security architecture for any cloud to be split into a set of modules. The continuous verification of security support on all levels (data, processes and communication channels) helps to avoid common security breaches and protect against the most dangerous attacks. Additionally, performing the proposed optimization of the selected set of mechanisms will enhance the efficiency of the security system.

Elements of Computation Theory (Texts in Computer Science)
by Arindama SinghThe foundation of computer science is built upon the following questions: What is an algorithm? What can be computed and what cannot be computed? What does it mean for a function to be computable? How does computational power depend upon programming constructs? Which algorithms can be considered feasible? For more than 70 years, computer scientists are searching for answers to such qu- tions. Their ingenious techniques used in answering these questions form the theory of computation. Theory of computation deals with the most fundamental ideas of computer s- ence in an abstract but easily understood form. The notions and techniques employed are widely spread across various topics and are found in almost every branch of c- puter science. It has thus become more than a necessity to revisit the foundation, learn the techniques, and apply them with con?dence. Overview and Goals This book is about this solid, beautiful, and pervasive foundation of computer s- ence. It introduces the fundamental notions, models, techniques, and results that form the basic paradigms of computing. It gives an introduction to the concepts and mathematics that computer scientists of our day use to model, to argue about, and to predict the behavior of algorithms and computation. The topics chosen here have shown remarkable persistence over the years and are very much in current use.
