""Educational Social Software for Context-Aware Learning: Collaborative Methods and Human Interaction"" examines socio-cultural elements in educational computing focused on design and theory where learning and setting are intertwined. This advanced publication addresses real-life case studies where evaluations have been applied and validated in computational systems.

Interactive Operations Research with Maple - Methods and Models (Hardcover, 2000 ed.): Mahmut Parlar Interactive Operations Research with Maple - Methods and Models (Hardcover, 2000 ed.)
Mahmut Parlar
R1,771 Discovery Miles 17 710 Ships in 12 - 19 working days

This work fills an important gap in the literature by providing an important link between MAPLE and its successful use in solving problems in Operations Research (OR). The symbolic, numerical, and graphical aspects of MAPLE make this software package an ideal tool for treating certain OR problems and providing descriptive and optimization-based analyses of deterministic and stochastic models. Detailed is MAPLE's treatment of some of the mathematical techniques used in OR modeling: e.g., algebra and calculus, ordinary and partial differential equations, linear algebra, transform methods, and probability theory.

A number of examples of OR techniques and applications are presented, such as linear and nonlinear programming, dynamic programming, stochastic processes, inventory models, queueing systems, and simulation. Throughout the text MAPLE statements used in the solutions of problems are clearly explained. At the same time, technical background material is presented in a rigorous mathematical manner to reach the OR novice and professional. Numerous end-of- chapter exercises, a good bibliography and overall index at the end of the book are also included, as well as MAPLE worksheets that are easily downloadable from the author's website at www.business.mcmaster.ca/msis/profs/parlar, or from the Birkhauser website at www.birkhauser.com/cgi-win/ISBN/0-8176-4165-3.

The book is intended for advanced undergraduate and graduate students in operations research, management science departments of business schools, industrial and systems engineering, economics, and mathematics. As a self-study resource, the text can be used by researchers and practitioners who want a quick overview ofMAPLE's usefulness in solving realistic OR problems that would be difficult or impossible to solve with other software packages.

For years, companies have rewarded their most effective engineers by suggesting they move to a management position. But treating management as the default (or only) path for an engineer with leadership ability doesn't serve the industry well. The staff engineer path allows you to contribute at a high level, with more free time to drive big projects, determine tech strategy, and raise everyone's skills. With this in-depth book, author Tanya Reilly shows you ways to master strategic thinking, manage difficult projects, and set the standard for technical work. You'll learn how to be a leader without direct authority, how to plan ahead so that you're making the right technical decisions, and how to make everyone around you better, all while still leaving you time to grow as an expert in your domain. In three parts, you'll explore the three pillars of an engineer's job: Big picture thinking: learn how to take a broad, strategic view when thinking about your work Project execution: dive into tactics and explore the practicalities of making projects succeed Being a positive influence: determine the standards for what "good engineering" means in your organization

R15,195 Discovery Miles 151 950 Ships in 10 - 15 working days

Non-Functional Requirements in Software Engineering presents a systematic and pragmatic approach to `building quality into' software systems. Systems must exhibit software quality attributes, such as accuracy, performance, security and modifiability. However, such non-functional requirements (NFRs) are difficult to address in many projects, even though there are many techniques to meet functional requirements in order to provide desired functionality. This is particularly true since the NFRs for each system typically interact with each other, have a broad impact on the system and may be subjective. To enable developers to systematically deal with a system's diverse NFRs, this book presents the NFR Framework. Structured graphical facilities are offered for stating NFRs and managing them by refining and inter-relating NFRs, justifying decisions, and determining their impact. Since NFRs might not be absolutely achieved, they may simply be satisfied sufficiently (`satisficed'). To reflect this, NFRs are represented as `softgoals', whose interdependencies, such as tradeoffs and synergy, are captured in graphs. The impact of decisions is qualitatively propagated through the graph to determine how well a chosen target system satisfices its NFRs. Throughout development, developers direct the process, using their expertise while being aided by catalogues of knowledge about NFRs, development techniques and tradeoffs, which can all be explored, reused and customized. Non-Functional Requirements in Software Engineering demonstrates the applicability of the NFR Framework to a variety of NFRs, domains, system characteristics and application areas. This will help readers apply the Framework to NFRs and domains of particular interest to them. Detailed treatments of particular NFRs - accuracy, security and performance requirements - along with treatments of NFRs for information systems are presented as specializations of the NFR Framework. Case studies of NFRs for a variety of information systems include credit card and administrative systems. The use of the Framework for particular application areas is illustrated for software architecture as well as enterprise modelling. Feedback from domain experts in industry and government provides an initial evaluation of the Framework and some case studies. Drawing on research results from several theses and refereed papers, this book's presentation, terminology and graphical notation have been integrated and illustrated with many figures. Non-Functional Requirements in Software Engineering is an excellent resource for software engineering practitioners, researchers and students.

R4,426 Discovery Miles 44 260 Ships in 10 - 15 working days

Chaos-based cryptography, attracting many researchers in the past decade, is a research field across two fields, i.e., chaos (nonlinear dynamic system) and cryptography (computer and data security). It Chaos' properties, such as randomness and ergodicity, have been proved to be suitable for designing the means for data protection. The book gives a thorough description of chaos-based cryptography, which consists of chaos basic theory, chaos properties suitable for cryptography, chaos-based cryptographic techniques, and various secure applications based on chaos. Additionally, it covers both the latest research results and some open issues or hot topics. The book creates a collection of high-quality chapters contributed by leading experts in the related fields. It embraces a wide variety of aspects of the related subject areas and provide a scientifically and scholarly sound treatment of state-of-the-art techniques to students, researchers, academics, personnel of law enforcement and IT practitioners who are interested or involved in the study, research, use, design and development of techniques related to chaos-based cryptography.

Semantic Integration of Heterogeneous Software Specifications (Hardcover, 2004 ed.): Martin Grosse-Rhode Semantic Integration of Heterogeneous Software Specifications (Hardcover, 2004 ed.)
Martin Grosse-Rhode
R4,393 Discovery Miles 43 930 Ships in 10 - 15 working days

In a model-based development of software systems different views on a system are elaborated using appropriate modeling languages and techniques. Because of the unavoidable heterogeneity of the viewpoint models, a semantic integration is required, to establish the correspondences of the models and allow checking of their relative consistency.

The integration approach introduced in this book is based on a common semantic domain of abstract systems, their composition and development. Its applicability is shown through semantic interpretations and compositional comparisons of different specification approaches. These range from formal specification techniques like process calculi, Petri nets and rule-based formalisms to semiformal software modeling languages like those in the UML family.

R4,426 Discovery Miles 44 260 Ships in 10 - 15 working days

Requirements engineering has since long acknowledged the importance of the notion that system requirements are stakeholder goals-rather than system functions-and ought to be elicited, modeled and analyzed accordingly. In this book, Nurcan and her co-editors collected twenty contributions from leading researchers in requirements engineering with the intention to comprehensively present an overview of the different perspectives that exist today, in 2010, on the concept of intention in the information systems community. These original papers honor Colette Rolland for her contributions to this field, as she was probably the first to emphasize that 'intention' has to be considered as a first-class concept in information systems engineering. Written by long-term collaborators (and most often friends) of Colette Rolland, this volume covers topics like goal-oriented requirements engineering, model-driven development, method engineering, and enterprise modeling. As such, it is a tour d'horizon of Colette Rolland's lifework, and is presented to her on the occasion of her retirement at CaISE 2010 in Hammamet, the conference she once cofounded and which she helped to grow and prosper for more than 20 years.

SMIL 3.0: Multimedia for the Web, Mobile Devices and Daisy Talking Books is a revised introduction to - and resource guide for - the W3C SMIL language. It covers all aspects of the SMIL specification and covers all of SMIL's implem- tation profiles, from the desktop through the world of mobile SMIL devices. Based on the first version of the book, which covered SMIL 2.0, this edition has been updated with information from the past two releases of the SMIL l- guage. We have benefitted from comments and suggestions from many readers of the first edition, and have produced what we feel is the most comprehensive guide to SMIL available anywhere. Motivation for this Book While we were working on various phases of the SMIL recommendations, it became clear to us that the richness of the SMIL language could easily ov- whelm many Web authors and designers. In the 500+ pages that the SYMM working group needed to describe the 30+ SMIL elements and the 150+ SMIL attributes, there was not much room for background information or extensive examples. The focus of the specification was on implementation aspects of the SMIL language, not on the rationale or the potential uses of SMIL's declarative power.

R4,648 Discovery Miles 46 480 Ships in 10 - 15 working days

This book initiates a new digital multimedia standards series. The purpose of the series is to make information about digital multimedia standards readilyavailable. Both tutorial and advanced topics will be covered in the series, often in one book. Our hope is that users will find the series helpful in deciding what standards to support and use while implementors will d- cover a wealth of technical details that help them implement those standards correctly. In today's global economy standards are increasingly important. Yet until a standard is widely used, most of the benefits of standardization are not realized. We hope that standards committee chairpeople will organize and encourage a book in this series devoted to their new standard. This can be a forum to share and preserve some ofthe "why" and "how" that went into the development of the standard and, in the process, assist in the rapid adoption of the standard. Already in production for this series are books titled Digital Video: - troduction to MPEG-2 and Data Compression in Digital Systems.

R3,000 Discovery Miles 30 000 Ships in 10 - 15 working days

This book is concerned with topological and differential properties of multivalued mappings and marginal functions. Beside this applica- tions to the sensitivity analysis of optimization problems, in particular nonlinear programming problems with perturbations, are studied. The elaborated methods are primarily obtained by theories and concepts of two former Soviet Union researchers, Demyanov and Rubinov. Con- sequently, a significant part of the presented results have never been published in English before. Based on the use of directional derivatives as a key tool in studying nonsmooth functions and multifunctions, these results can be considered as a further development of quasidifferential calculus created by Demyanov and Rubinov. In contrast to other research in this field, especially the recent publica- tion by Bonnans and Shapiro, this book analyses properties of marginal functions associated with optimization problems under quite general con- straints defined by means of multivalued mappings. A unified approach to directional differentiability of functions and multifunctions forms the base of the volume.

The Functional Treatment of Parsing (Hardcover, 1993 ed.): Rene Leermakers The Functional Treatment of Parsing (Hardcover, 1993 ed.)
Rene Leermakers
R2,971 Discovery Miles 29 710 Ships in 10 - 15 working days

Parsing technology traditionally consists of two branches, which correspond to the two main application areas of context-free grammars and their generalizations. Efficient deterministic parsing algorithms have been developed for parsing programming languages, and quite different algorithms are employed for analyzing natural language. The Functional Treatment of Parsing provides a functional framework within which the different traditional techniques are restated and unified. The resulting theory provides new recursive implementations of parsers for context-free grammars. The new implementations, called recursive ascent parsers, avoid explicit manipulation of parse stacks and parse matrices, and are in many ways superior to conventional implementations. They are applicable to grammars for programming languages as well as natural languages. The book has been written primarily for students and practitioners of parsing technology. With its emphasis on modern functional methods, however, the book will also be of benefit to scientists interested in functional programming. The Functional Treatment of Parsing is an excellent reference and can be used as a text for a course on the subject.

The art, craft, discipline, logic, practice, and science of developing large-scale software products needs a believable, professional base. The textbooks in this three-volume set combine informal, engineeringly sound practice with the rigour of formal, mathematics-based approaches.

Volume 3 is based on the maxim: "Before software can be designed its requirements must be well understood, and before the requirements can be expressed properly the domain of the application must be well understood." This book covers the process from the development of domain descriptions, via the derivation of requirements prescriptions from domain models, to the refinement of requirements into software designs, i.e., architectures and component design. Emphasis is placed on what goes into proper domain descriptions and requirements prescriptions, how one acquires and analyses the domain knowledge and requirements expectations, and how one validates and verifies domain and requirements models.

The reader can take an informal route through Vol. 3, and this would be suitable for undergraduate courses on software engineering. Advanced students, lecturers, and researchers may instead follow the formal route through Vol. 3, and in this case Vol. 1 is a prerequisite text. Lecturers will be supported with a comprehensive guide to designing modules based on the textbooks, with solutions to many of the exercises presented, and with a complete set of lecture slides.

R4,489 Discovery Miles 44 890 Ships in 10 - 15 working days

Both object orientation and parallelism are modern programming paradigms which have gained much popularity in the last 10-15 years. Object orientation raises hopes for increased productivity of software generation and maintenance methods. Parallelism can serve to structure a problem but also promises faster program execution. The two areas of computing science in which these paradigms play the most prominent role are programming languages and databases. In programming languages, one can take an academic approach with a primary focus on the generality of the semantics of the language constructs which support the respective paradigm. In databases, one is willing to restrict the power of the constructs in the interest of increased efficiency. Inter- and intra-object parallelism have received an increasing amount of attention in the last few years by researchers in the area of object- oriented programming. At first glance, an object is very similar to a process which offers services to other processes and demands services from them. It has, however, transpired that object-oriented concepts cause problems when combined with parallelism. In programming languages, the introduction of parallelism and the synchronization constraints it brings with it can get in the way of code reusability. In databases, the combination of object orientation and parallelism requires, for example, a generalization of the transaction model, new approaches to the specification of information systems, an implementation model of object communication, and the design of an overall system architecture. There has been insufficient communication between researchers in programming languages and in databases on these issues. Object Orientation with Parallelism and Persistence grew out of a Dagstuhl Seminar of the same title in April 1995 whose goal it was to put the new research area object orientation with parallelism' on an interdisciplinary basis. Object Orientation with Parallelism and Persistence will be of interest to researchers and professionals working in software engineering, programming languages, and database systems.

Computability of Julia Sets (Hardcover, 2009 ed.): Mark Braverman, Michael Yampolsky Computability of Julia Sets (Hardcover, 2009 ed.)
Mark Braverman, Michael Yampolsky
R1,613 Discovery Miles 16 130 Ships in 10 - 15 working days

Among all computer-generated mathematical images, Julia sets of rational maps occupy one of the most prominent positions. Their beauty and complexity can be fascinating. They also hold a deep mathematical content.

Computational hardness of Julia sets is the main subject of this book. By definition, a computable set in the plane can be visualized on a computer screen with an arbitrarily high magnification. There are countless programs to draw Julia sets. Yet, as the authors have discovered, it is possible to constructively produce examples of quadratic polynomials, whose Julia sets are not computable. This result is striking - it says that while a dynamical system can be described numerically with an arbitrary precision, the picture of the dynamics cannot be visualized.

The book summarizes the present knowledge (most of it from the authors' own work) about the computational properties of Julia sets in a self-contained way. It is accessible to experts and students with interest in theoretical computer science or dynamical systems.
