G eant 4 is a toolkit for simulating the passage of particles through matter. It includes a complete range of functionality including tracking, geometry, physics models and hits. The physics processes offered cover a comprehensive range, including electromagnetic, hadronic and optical processes, a large set of long-lived particles, materials and elements, over a wide energy range starting, in some cases, from 250 eV and extending in others to the TeV energy range. It has been designed and constructed to expose the physics models utilised, to handle complex geometries, and to enable its easy adaptation for optimal use in different sets of applications. The toolkit is the result of a worldwide collaboration of physicists and software engineers. It has been created exploiting software engineering and object-oriented technology and implemented in the C++ programming language. It has been used in applications in particle physics, nuclear physics, accelerator design, space engineering and medical physics.

In The Unified Modeling Language User Guide, the original developers of the UML--Grady Booch, James Rumbaugh, and Ivar Jacobson--provide a tutorial to the core aspects of the language in a two-color format designed to facilitate learning. Starting with a conceptual model of the UML, the book progressively applies the UML to a series of increasingly complex modeling problems across a variety of application domains. This example-driven approach helps readers quickly understand and apply the UML. For more advanced developers, the book includes a learning track focused on applying the UML to advanced modeling problems.With The Unified Modeling Language User Guide, readers will:Understand what the UML is, what it is not, and why it is relevant to the development of software-intensive systemsMaster the vocabulary, rules, and idioms of the UML in order to "speak" the language effectivelyLearn how to apply the UML to a number of common modeling problemsSee illustrations of the UML's use interspersed with use cases for specific UML features, andGain insight into the UML from the original creators of the UML.

Geant4 - A Simulation Toolkit

Given the central role that software development plays in the delivery and application of information technology, managers are increasingly focusing on process improvement in the software development area. This demand has spurred the provision of a number of new and/or improved approaches to software development, with perhaps the most prominent being object-orientation (OO). In addition, the focus on process improvement has increased the demand for software measures, or metrics with which to manage the process. The need for such metrics is particularly acute when an organization is adopting a new technology for which established practices have yet to be developed. This research addresses these needs through the development and implementation of a new suite of metrics for OO design. Metrics developed in previous research, while contributing to the field's understanding of software development processes, have generally been subject to serious criticisms, including the lack of a theoretical base. Following Wand and Weber (1989), the theoretical base chosen for the metrics was the ontology of Bunge (1977). Six design metrics are developed, and then analytically evaluated against Weyuker's (1988) proposed set of measurement principles. An automated data collection tool was then developed and implemented to collect an empirical sample of these metrics at two field sites in order to demonstrate their feasibility and suggest ways in which managers may use these metrics for process improvement. >

Prior research has provided valuable insights into how and why employees make a decision about the adoption and use of information technologies (ITs) in the workplace. From an organizational point of view, however, the more important issue is how managers make informed decisions about interventions that can lead to greater acceptance and effective utilization of IT. There is limited research in the IT implementation literature that deals with the role of interventions to aid such managerial decision making. Particularly, there is a need to understand how various interventions can influence the known determinants of IT adoption and use. To address this gap in the literature, we draw from the vast body of research on the technology acceptance model (TAM), particularly the work on the determinants of perceived usefulness and perceived ease of use, and: (i) develop a comprehensive nomological network (integrated model) of the determinants of individual level (IT) adoption and use; (ii) empirically test the proposed integrated model; and (iii) present a research agenda focused on potential pre- and postimplementation interventions that can enhance employees' adoption and use of IT. Our findings and research agenda have important implications for managerial decision making on IT implementation in organizations.

One of the most intriguing ways that commercial developers of software can become more efficient is to reuse not only software but also best practices from the open-source movement The open-source movement encompasses a wide collection of ideas, knowledge, techniques, and solutions Commercial software vendors have an opportunity to both learn from the open-source community, as well as leverage that knowledge for the benefit of its commercial clients This paper looks at a number of the characteristics of the open-source movement, offers a categorization of open-source dimensions, and provides an analysis of the opportunities available to commercial software vendors when applying the lessons from the open-source movement

Reusing Open-Source Software and Practices: The Impact of Open-Source on Commercial Vendors

Computing has transformed humanity in ways that we have only begun to metabolize. Computing amplifies what we celebrate most about being human, but it also has the capacity to magnify that which we mourn. Exploring the story of computing has value, for an educated populace is far more able to reconcile its past, reason about its present, and be intentional about its future.

Object-Oriented Design with Applications has long been the essential reference to object-oriented technology, which, in turn, has evolved to join the mainstream of industrial-strength software development. In this third edition--the first revision in 13 years--readers can learn to apply object-oriented methods using new paradigms such as Java, the Unified Modeling Language (UML) 2.0, and .NET.The authors draw upon their rich and varied experience to offer improved methods for object development and numerous examples that tackle the complex problems faced by software engineers, including systems architecture, data acquisition, cryptoanalysis, control systems, and Web development. They illustrate essential concepts, explain the method, and show successful applications in a variety of fields. You'll also find pragmatic advice on a host of issues, including classification, implementation strategies, and cost-effective project management.New to this new edition are An introduction to the new UML 2.0, from the notation's most fundamental and advanced elements with an emphasis on key changes New domains and contexts A greatly enhanced focus on modeling--as eagerly requested by readers--with five chapters that each delve into one phase of the overall development lifecycle. Fresh approaches to reasoning about complex systems An examination of the conceptual foundation of the widely misunderstood fundamental elements of the object model, such as abstraction, encapsulation, modularity, and hierarchy How to allocate the resources of a team of developers and mange the risks associated with developing complex software systems An appendix on object-oriented programming languagesThis is the seminal text for anyone who wishes to use object-oriented technology to manage the complexity inherent in many kinds of systems.Sidebarsi¾ i¾ Prefacei¾ Acknowledgments i¾ i¾ About the Authors i¾ i¾ Section I: Conceptsi¾ i¾ Chapter 1: Complexityi¾ i¾ i¾ Chapter 2: The Object Model i¾ i¾ Chapter 3: Classes and Objects i¾ i¾ Chapter 4: Classification i¾ i¾ Section II: Method i¾ Chapter 5: Notation i¾ i¾ Chapter 6: Process Chapter 7: Pragmaticsi¾ i¾ i¾ Chapter 8: System Architecture: Satellite-Based Navigation i¾ i¾ Chapter 9: Control System: Traffic Management i¾ i¾ Chapter 10: Artificial Intelligence: Cryptanalysis i¾ i¾ Chapter 11: Data Acquisition: Weather Monitoring Station i¾ Chapter 12: Web Application: Vacation Tracking System i¾ i¾ i¾ Appendix A: Object-Oriented Programming Languagesi¾ Appendix B: Further Reading i¾ i¾ Notes i¾ i¾ Glossary i¾ i¾ Classified Bibliography i¾ i¾ Index i¾ i¾
