Introduction to JavaScript Object Notation

No one can dispute the impact Grady Booch's writings have had on object-oriented technology. The Best of Booch contains articles on various object-oriented topics published since Grady Booch's book Object Oriented Modeling and Design with Applications, second edition. Designed for software professionals who are concerned about the success of their object-oriented projects, this volume covers all aspects of the Booch method and how a complete method must address a model's notation and semantics as well as a process for creating that model. Many of the articles have been updated to reflect the current thinking in the Unified Modeling Language (UML).

This book is a cross-cultural reference volume of all attested numerical notation systems (graphic, non-phonetic systems for representing numbers), encompassing more than 100 such systems used over the past 5,500 years. Using a typology that defies progressive, unilinear evolutionary models of change, Stephen Chrisomalis identifies five basic types of numerical notation systems, using a cultural phylogenetic framework to show relationships between systems and to create a general theory of change in numerical systems. Numerical notation systems are primarily representational systems, not computational technologies. Cognitive factors that help explain how numerical systems change relate to general principles, such as conciseness or avoidance of ambiguity, which apply also to writing systems. The transformation and replacement of numerical notation systems relates to specific social, economic, and technological changes, such as the development of the printing press or the expansion of the

Michael McMillan provides a complete presentation of the object-oriented features of the Visual Basic .NET language for advanced Visual Basic programmers. Beginning with an introduction to abstract data types and their initial implementation using structures, he explains standard OOP topics including class design, inheritance, access modifiers and scoping issues, abstract classes, design and implemention of interfaces and design patterns, and refactoring in VB.NET. More advanced OOP topics are included as well, such as reflection, object persistence, and serialization. To tie everything together, McMillan demonstrates sound OOP design and implementation principles through practical examples of standard Windows applications, database applications using ADO.NET, Web-based applications using ASP.NET, and Windows service applications.

Using CRC Cards, first published in 1995, is a comprehensive introduction to CRC (Class, Responsibility, Collaborator) cards. It includes a description of the cards and how they can be used in interactive sessions to develop an object-oriented model of an application. In this book, the author draws on her years of project experience to describe how CRC cards can contribute at all stages of the software lifecycle. It includes practical examples of how to utilize CRC cards in projects using either formal or informal development techniques. Using CRC Cards also provides a detailed look at how designs created with CRC cards can be mapped to an effective and efficient implementation in C++. Software analysts, designers and developers will find this a practical handbook for using CRC cards. It guides the transition to the object-oriented paradigm as well as providing a process for the development of object-oriented applications. In addition, software managers will gain an understanding of t

Musical notation has not always existed: in the West, musical traditions have often depended on transmission from mouth to ear, and ear to mouth. Although the Ancient Greeks had a form of musical notation, it was not passed on to the medieval Latin West. This comprehensive study investigates the breadth of use of musical notation in Carolingian Europe, including many examples previously unknown in studies of notation, to deliver a crucial foundational model for the understanding of later Western notations. An overview of the study of neumatic notations from the French monastic scholar Dom Jean Mabillon (1632–1707) up to the present day precedes an examination of the function and potential of writing in support of a musical practice which continued to depend on trained memory. Later chapters examine passages of notation to reveal those ways in which scripts were shaped by contemporary rationalizations of musical sound. Finally, the new scripts are situated in the cultural and social con

Kalman filter, particle filter, IMM, PDA, ITS, random sets... The number of useful object-tracking methods is exploding. But how are they related? How do they help track everything from aircraft, missiles and extra-terrestrial objects to people and lymphocyte cells? How can they be adapted to novel applications? Fundamentals of Object Tracking tells you how. Starting with the generic object-tracking problem, it outlines the generic Bayesian solution. It then shows systematically how to formulate the major tracking problems – maneuvering, multiobject, clutter, out-of-sequence sensors – within this Bayesian framework and how to derive the standard tracking solutions. This structured approach makes very complex object-tracking algorithms accessible to the growing number of users working on real-world tracking problems and supports them in designing their own tracking filters under their unique application constraints. The book concludes with a chapter on issues critical to successful impl

Scala is a highly expressive, concise and scalable language. It is also the most prominent method of the new and exciting methodology known as object-functional programming. In this book, the authors show how Scala grows to the needs of the programmer, whether professional or hobbyist. They teach Scala with a step-by-step approach and explain how to exploit the full power of the industry-proven JVM technology. Readers can then dive into specially chosen design challenges and implementation problems, inspired by the trials of real-world software engineering. It also helps readers to embrace the power of static typing and automatic type inference. In addition, the book shows how to use the dual-object and functional-oriented natures combined at Scala's core, and so write code that is less 'boilerplate', giving a genuine increase in productivity.

This is the only book that walks COBOL users through the next phase of COBOL: Object-Oriented COBOL (OOCOBOL). Written by experts in COBOL programming, Object-Oriented COBOL teaches you how to integrate COBOL with object-oriented methodologies. It provides explanations and roadmaps that will help you understand, navigate, and successfully integrate analysis and design concepts with enabling OOCOBOL constructs. Designed for current COBOL users and based on the authors' experience teaching Object-Oriented COBOL, experienced COBOL programmers can use Object-Oriented COBOL to begin programming effectively with objects in as little as twelve weeks, significantly less than the steep learning curve of twelve to twenty-four months for Smalltalk and C++. Object-Oriented COBOL also includes extensive examples and experiences, written in OOCOBOL, that explain the defining traits of an object-oriented language, such as encapsulation, inheritance, and polymorphism.

First published in 1903, Antoine Meillet's Introduction a l'Étude comparative des langues Indo-Européennes exemplifies the key methodologies and insights of early twentieth-century comparative linguistics. Its primary aim, as Meillet states, was 'très limité': to provide a brief but comprehensive overview of the Indo-European languages and their shared linguistic structures. He accomplished this object and more in his Introduction, outlining a theory of language change that would influence a generation of linguists, including his students Émile Benveniste and André Martinet. Meillet's debt to his own mentor, Ferdinand de Saussure, is evident in his conception of language as simultaneously social and structural, a lived reality and a constantly evolving grammatical system. This second edition (1908) includes Meillet's extensive revisions and a new chapter on the development of Indo-European dialects. It remains a valuable introduction to the phonology, morphology, and grammar of the Ind

This edited volume presents a unique multidisciplinary perspective on the problem of visual object categorization. The result of a series of four highly successful workshops on the topic, the book gathers many of the most distinguished researchers from both computer and human vision to reflect on their experience, identify open problems, and foster a cross-disciplinary discussion with the idea that parallel problems and solutions have arisen in both domains. Twenty-seven of these workshop speakers have contributed chapters, including fourteen from computer vision and thirteen from human vision. Their contributions range from broad perspectives on the problem to more specific approaches, collectively providing important historical context, identifying the major challenges, and presenting recent research results. This multidisciplinary collection is the first of its kind on the topic of object categorization, providing an outstanding context for graduate students and researchers in both

Learn how to write technical applications in a modern object-oriented approach, using Fortran 90 or 95. This book will teach you how to stop focusing on the traditional procedural abilities of Fortran and to employ the principles of object-oriented programming to produce clear, highly efficient executable codes. Get ready now to take advantage of all the features of the finalized, fully object-oriented Fortran 200X! In addition to covering the OOP methodologies the book also covers the basic foundation of the language and good programming skills, making the book valuable also as a good migration tool for experienced Fortran programmers who want to smoothly pick up the OOP paradigm. The author highlights common themes by using comparisons with Matlab and C++ and uses numerous cross-referenced examples to convey all concepts quickly and clearly. Complete code for the examples is included on the book's web page.

This new edition of Introduction to Lattices and Order presents a radical reorganization and updating, though its primary aim is unchanged. The explosive development of theoretical computer science in recent years has, in particular, influenced the book's evolution: a fresh treatment of fixpoints testifies to this and Galois connections now feature prominently. An early presentation of concept analysis gives both a concrete foundation for the subsequent theory of complete lattices and a glimpse of a methodology for data analysis that is of commercial value in social science. Classroom experience has led to numerous pedagogical improvements and many new exercises have been added. As before, exposure to elementary abstract algebra and the notation of set theory are the only prerequisites, making the book suitable for advanced undergraduates and beginning graduate students. It will also be a valuable resource for anyone who meets ordered structures.

Distributed Object Architectures with CORBA is a guide to creating a software architecture comprising distributed components. While it is based on OMG's Common Object Request Broker Architecture (CORBA) standard, the principles also apply to architecture built with other technology (such as Microsoft's DCOM). As ORB products evolve to incorporate new additions to CORBA, the knowledge and experience required to build stable and scalable systems is not widespread. With this book the reader can develop the skills and knowledge that is necessary for building such systems. The book assumes a familiarity with object-oriented concepts and the basics of CORBA. Software developers who are new to building systems with CORBA-based technologies will find this book a useful guide to effective development.

Over the last ten years Kent Beck has written dozens of technical papers for the Smalltalk community, earning himself a reputation as both a gifted writer and thinker. Kent Beck's Guide to Better Smalltalk, is a collection of his best work from Object Magazine, The Smalltalk Report, Dr Dobbs Journal, and more. Each article has a new introduction that takes a retrospective view of the writing. Topics include: idioms and environments; methods and metamodels; architecture and pattern languages, objects, classes, inheritance, and all things Smalltalk. Nowhere else can one obtain such a complete collection of Beck's writing. While demonstrating the elegance of Smalltalk and how some of its most powerful features can be exploited profitably, this collection also illuminates breakthrough concepts in object-oriented development. This book is for Smalltalk programmers and anyone working in object-oriented software development.

This textbook provides an introduction to general relativity for mathematics undergraduates or graduate physicists. After a review of Cartesian tensor notation and special relativity the concepts of Riemannian differential geometry are introducted. More emphasis is placed on an intuitive grasp of the subject and a calculational facility than on a rigorous mathematical exposition. General relativity is then presented as a relativistic theory of gravity reducing in the appropriate limits to Newtonian gravity or special relativity. The Schwarzchild solution is derived and the gravitational red-shift, time dilation and classic tests of general relativity are discussed. There is a brief account of gravitational collapse and black holes based on the extended Schwarzchild solution. Other vacuum solutions are described, motivated by their counterparts in linearised general relativity. The book ends with chapters on cosmological solutions to the field equations. There are exercises attached to

First published in 1979, this volume presents an elementary and, as far as is practicable, non-mathematical introduction to radiation dosimetry. Where it proved necessary to use mathematical notation, it was kept to a simple level. The volume treats dosimetry from first principles, dealing with the interaction of the various radiations with matter, then defining dosimetric quantities and units and showing how the more important ones are measured. It concludes with a brief chapter on radiation protection. Although a number of dosimetric systems are described in some detail the treatment is by no means encyclopaedic. SI units appear throughout, including some which were not yet in universal use when the book was first published. Where it was considered necessary, the older non-SI units were also defined and conversion factors were given.

Musical notation is a powerful system of communication between musicians, using sophisticated symbolic, primarily non-verbal means to express musical events in visual symbols. Many musicians take the system for granted, having internalized it and their strategies for reading it and translating it into sound over long years of study and practice. This book traces the development of that system by combining chronological and thematic approaches to show the historical and musical context in which these developments took place. Simultaneously, the book considers the way in which this symbolic language communicates to those literate in it, discussing how its features facilitate or hinder fluent comprehension in the real-time environment of performance. Moreover, the topic of musical as opposed to notational innovation forms another thread of the treatment, as the author investigates instances where musical developments stimulated notational attributes, or notational innovations made practic

In the Book of Judges the narrator presents an image of the good parent YHWH whose enduring love and loyalty is offset by his wayward child Israel who defaults on the relationship repeatedly. Biblical scholars have largely concurred, demonstrating the many faults of Israel while siding with YHWH's privileged viewpoint. When object-relations theory (which examines how human beings relate to each other) is applied to Judges, a different story emerges. In its capacity to illuminate why and how relationships can be intense, problematic, rewarding, and enduring, object-relations theory reveals how both YHWH and Israel have attachment needs that are played out vividly in the story world. Deryn Guest reveals how its narrator engages in a variety of psychological strategies to mask suppressed rage as he engages in an intriguing but rather dysfunctional masochistic dance with a dominant deity who has reputation needs.

Branching Brownian motion (BBM) is a classical object in probability theory with deep connections to partial differential equations. This book highlights the connection to classical extreme value theory and to the theory of mean-field spin glasses in statistical mechanics. Starting with a concise review of classical extreme value statistics and a basic introduction to mean-field spin glasses, the author then focuses on branching Brownian motion. Here, the classical results of Bramson on the asymptotics of solutions of the F-KPP equation are reviewed in detail and applied to the recent construction of the extremal process of BBM. The extension of these results to branching Brownian motion with variable speed are then explained. As a self-contained exposition that is accessible to graduate students with some background in probability theory, this book makes a good introduction for anyone interested in accessing this exciting field of mathematics.

Originally published in 2002, this book presents techniques in the application of formal methods to object-based distributed systems. A major theme of the book is how to formally handle the requirements arising from OO distributed systems, such as dynamic reconfiguration, encapsulation, subtyping, inheritance, and real-time aspects. These may be supported either by enhancing existing notations, such as UML, LOTOS, SDL and Z, or by defining fresh notations, such as Actors, Pi-calculus and Ambients. The major specification notations and modelling techniques are introduced and compared by leading researchers. The book also includes a description of approaches to the specification of non-functional requirements, and a discussion of security issues. Researchers and practitioners in software design, object-oriented computing, distributed systems, and telecommunications systems will gain an appreciation of the relationships between the major areas of concerns and learn how the use of object-o

Supersymmetric models of particle physics predict new superpartner matter states for each particle in the Standard Model. These superpartners will have wide ranging implications, from cosmology to observations at high energy accelerators, such as CERN's LHC. In this 2006 text, the authors develop the basic concepts of supersymmetry and show how it can be incorporated into a theoretical framework for describing unified theories of elementary particles. They develop the technical tools of supersymmetry using four-component spinor notation familiar to high energy experimentalists and phenomenologists. The text takes the reader from an abstract formalism to a straightforward recipe for writing supersymmetric gauge theories of particle physics, and ultimately to the calculations necessary for practical applications at colliders and in cosmology. This is a comprehensive, practical and accessible introduction to supersymmetry for experimental and phenomenological particle physicists and gradu

Dance played a major role in all French Baroque theatrical entertainments. Le Mariage de la Grosse Cathos, a short ballet performed at the court of Louis XIV, is of major importance, largely because it has survived complete in all its components - choreography, music, and text - and also because it uses a previously unknown dance notation system. This book reproduces the entire manuscript of this ballet and provides a comprehensive study of the work itself and of the circumstances in which it was created and performed. Chapters devoted to the composer, choreographer, and performers provide a framework for understanding the performance context not only of this work, but of other court entertainments of the period. A study and evaluation of the notation system in which the dances are recorded, together with a detailed analysis of the dances, completes the introduction.

The authors describe here a framework in which the type notation of functional languages is extended to include a notation for binding times (that is run-time and compile-time) that distinguishes between them. Consequently the ability to specify code and verify program correctness can be improved. Two developments are needed, the first of which introduces the binding time distinction into the lambda calculus, in a manner analogous with the introduction of types into the untyped lambda calculus. Methods are also presented for introducing combinators for run-time. The second concerns the interpretation of the resulting language, which is known as the mixed lambda-calculus and combinatory logic. The notion of 'parametrized semantics' is used to describe code generation and abstract interpretation. The code generation is for a simple abstract machine designed for the purpose; it is close to the categorical abstract machine. The abstract interpretation focuses on a strictness analysis that
