Category theory is a general mathematical theory of structures and of structures of structures. It occupied a central position in contemporary mathematics as well as computer science. This book describes the history of category theory whereby illuminating its symbiotic relationship to algebraic topology, homological algebra, algebraic geometry and mathematical logic and elaboratively develops the connections with the epistemological significance.

Tool-Being offers a new assessment of Martin Heidegger's famous tool-analysis, and with it, an audacious reappraisal of Heidegger's legacy to twenty-first-century philosophy. Every reader of Being and Time is familiar with the opposition between readiness-to-hand (Zuhandenheit) and presence-at-hand (Vorhandenheit), but commentators usually follow Heidegger's wishes in giving this distinction a limited scope, as if it applied only to tools in a narrow sense. Graham Harman contests Heidegger's own interpretation of tool-being, arguing that the opposition between tool and broken tool is not merely a provisional stage in his philosophy, but rather its living core. The extended concept of tool-being developed here leads us not to a theory of human practical activity but to an ontology of objects themselves. Tool-Being urges a fresh and concrete research into the secret contours of objects. Written in a lively and colorful style, it will be of great interest to anyone intrigued by Heidegger and anyone open to new trends in present-day philosophy.

Object Thinking blends historical perspective, experience, and visionary insight - exploring how developers can work less like the computers they program and more like problem solvers.

Object technology pioneer Wirfs-Brock teams with expert McKean to present a thoroughly updated, modern, and proven method for the design of software. The book is packed with practical design techniques that enable the practitioner to get the job done.

Concern identification aims to find the implementation of a functional concern in existing source code. In this work, concerns are described, using the Hierarchic Concern Model, as gray-boxes containing subconcerns, inputs, and outputs. The inputs and outputs are used as concern seeds to identify data-oriented abstractions of concern implementations, called concern skeletons. The identification approach is based on context free language reachability and supported by a tool, called CoDEx.

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.

This is a new edition of this pack which covers the three leading object modelling notations, Coad, OMT and the new Unified (Booch-Rumbaugh) methodology. It presents 177 state-of-the-art strategies and 31 patterns for object model development. The new edition includes 29 new strategies which include: using feature milestones to deliver results more quickly; extracting useful content from data models; using patterns to discover new features, separating definition from usage; when to use, or not use, inheritance; how to decide whether you need an attribute or something more; and why you should nearly always ask for more than a data value.

Object-Process Methodology (OPM) is an intuitive approach to systems engineering. This book presents the theory and practice of OPM with examples from various industry segments and engineering disciplines, as well as daily life. OPM is a generic, domain independent approach that is applicable almost anywhere in systems engineering.

Driven by demand from the entertainment industry for better and more realistic animation, technology continues to evolve and improve. The algorithms and techniques behind this technology are the foundation of this comprehensive book, which is written to teach you the fundamentals of animation programming. In this third edition, the most current techniques are covered along with the theory and high-level computation that have earned the book a reputation as the best technically-oriented animation resource. Key topics such as fluids, hair, and crowd animation have been expanded, and extensive new coverage of clothes and cloth has been added. New material on simulation provides a more diverse look at this important area and more example animations and chapter projects and exercises are included. Additionally, spline coverage has been expanded and new video compression and formats (e.g., iTunes) are covered. - Includes companion site with contemporary animation examples drawn from research and entertainment, sample animations, and example code - Describes the key mathematical and algorithmic foundations of animation that provide you with a deep understanding and control of technique - Expanded and new coverage of key topics including: fluids and clouds, cloth and clothes, hair, and crowd animation - Explains the algorithms used for path following, hierarchical kinematic modelling, rigid body dynamics, flocking behaviour, particle systems, collision detection, and more
