Are you looking for a more effective approach to real-time systems development? Real-Time Object-Oriented Modeling The development of real-time distributed systems is one of the most difficult engineering problems ever faced, taxing the capabilities of traditional real-time software development approaches. Real-Time Object-Oriented Modeling is the first book that brings together, in a single harmonious approach, the power of object-oriented concepts tailored specifically for real-time systems, with an iterative and incremental process based on the use of executable models. Developed by practitioners, the proven methodology described here is becoming a leader in the industry. Using a learn-by-example approach, this book offers: * A single consistent set of graphical modeling concepts, chosen to improve developer effectiveness, which apply uniformly to analysis, design, and implementation. This reduces the learning curve to master the entire method and eliminates expensive discontinuities across different stages of development. * An approach to the object paradigm that is easy to learn and that applies to the construction of reusable architectural design components, not just low-level language elements. This unleashes the true power of the object paradigm. * Techniques for constructing executable models to gain early confidence in specifications and design decisions. * Approaches to project management that deliver the benefits of the object paradigm and executable models.

Provides an introduction to modern object-oriented design principles and applications for the fast-growing area of modeling and simulation Covers the topic of multi-domain system modeling and design with applications that have components from several areas Serves as a reference for the Modelica language as well as a comprehensive overview of application model libraries for a number of application domains

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. This book focuses squarely on object-oriented Ruby application design. Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

This practical new book provides much-needed, practical, hands-on experience capturing analysis and design in UML. It holds the hands of engineers making the difficult leap from developing in C to the higher-level and more robust Unified Modeling Language, thereby supporting professional development for engineers looking to broaden their skill-sets in order to become more saleable in the job market. It provides a laboratory environment through a series of progressively more complex exercises that act as building blocks, illustrating the various aspects of UML and its application to real-time and embedded systems. With its focus on gaining proficiency, it goes a significant step beyond basic UML overviews, providing both comprehensive methodology and the best level of supporting exercises available on the market. Each exercise has a matching solution which is thoroughly explained step-by-step in the back of the book. The techniques used to solve these problems come from the author's decades of experience designing and constructing real-time systems. After the exercises have been successfully completed, the book will act as a desk reference for engineers, reminding them of how many of the problems they face in their designs can be solved. - Tutorial style text with keen focus on in-depth presentation and solution of real-world example problems - Highly popular, respected and experienced author

Object-oriented techniques and languages have been proven to significantly increase engineering efficiency in software development. Many benefits are expected from their introduction into electronic modeling. Among them are better support for model reusability and flexibility, more efficient system modeling, and more possibilities in design space exploration and prototyping. Object-Oriented Modeling explores the latest techniques in object-oriented methods, formalisms and hardware description language extensions. The seven chapters comprising this book provide an overview of the latest object-oriented techniques for designing systems and hardware. Many examples are given in C++, VHDL and real-time programming languages. Object-Oriented Modeling describes further the use of object-oriented techniques in applications such as embedded systems, telecommunications and real-time systems, using the very latest techniques in object-oriented modeling. It is an essential guide to researchers, practitioners and students involved in software, hardware and system design.
