A Rigorous Semantics for BPMN 2.0 Process Diagrams

By: Felix Kossak,Christa Illibauer,Verena Geist,Jan Kubovy,Christine Natschläger,Thomas Ziebermayr,Theodorich Kopetzky,Bernhard Freudenthaler,Klaus-Dieter Schewe

This book provides the most complete formal specification of the semantics of the Business Process Model and Notation 2.0 standard (BPMN) available to date, in a style that is easily understandable for a wide range of readers – not only for experts in formal methods, but e.g. also for developers of modeling tools, software architects, or graduate students specializing in business process management. BPMN – issued by the Object Management Group – is a widely used standard for business process modeling. However, major drawbacks of BPMN include its limited support for organizational modeling, its only implicit expression of modalities, and its lack of integrated user interaction and data modeling. Further, in many cases the syntactical and, in particular, semantic definitions of BPMN are inaccurate, incomplete or inconsistent. The book addresses concrete issues concerning the execution semantics of business processes and provides a formal definition of BPMN process diagrams, which can serve as a sound basis for further extensions, i.e., in the form of horizontal refinements of the core language. To this end, the Abstract State Machine (ASMs) method is used to formalize the semantics of BPMN. ASMs have demonstrated their value in various domains, e.g. specifying the semantics of programming or modeling languages, verifying the specification of the Java Virtual Machine, or formalizing the ITIL change management process. This kind of improvement promotes more consistency in the interpretation of comprehensive models, as well as real exchangeability of models between different tools. In the outlook at the end of the book, the authors conclude with proposing extensions that address actor modeling (including an intuitive way to denote permissions and obligations), integration of user-centric views, a refined communication concept, and data integration.

On Picture Making and Picture Seeing

A Brief Discourse

By: Jan B. Deręgowski

Archaeological and anthropological investigations of depictions seldom extend beyond a single culture or a single geographical location, although there is a powerful factor common to all depictions, the factor of human perception. In this volume an attempt is made to show how this factor affects both creation and recognition of depictions, how, in common with everyday vision of the environment, typical contours are derived and used, not merely to depict individually readily recognisable models, but also how by concatenation they lead to such a splendid figure as Australian Kakadu crocodiles, or by distortion to creation of illusions of pictorial depth, such as is evoked by Leonardo da Vinci’s perspective and by inverted (Byzantine) perspective thought by some to be an aberration. Bartel’s studies show that pictorial depth is often achieved to the artist’s, and many a viewer’s, but not to geometer’s satisfaction by partial distortion, and Chinese masterpieces embody, side by side, ‘normal’ and inverted perspective. The visual process is universally uniform (if it were not, one would not be able to recognise an Altamira bison as a bison) and its foibles can be freely exploited. Its best known exploiter is probably Cezanne. His pictures are admired by many and puzzle many. Strzemiński postulated that they compound distinct lines of sight, thus endorsing primacy of central vision, a concept thought by Gombrich to be of greater import to geometers than to artists.

Once upon a Time in the West

Essays on the Politics of Thought and Imagination

By: Jan Zwicky

Western civilization is over. So begins Jan Zwicky’s trenchant exploration of the root of global cultural and ecological collapse: a way of thinking that is also linked to some of the West’s most noted achievements. The Renaissance merged imperial enterprise with Islamic algebra and recently recovered Greek mathematics to precipitate mechanized industry and resource extraction; these in turn made possible the growth of capitalism, the military-industrial complex, and Big Technology. Despite its self-image as objective, Zwicky argues, the West’s style of thought is not politically neutral, but intensely anthropocentric. It has led those who adopt it to regard the more-than-human world as nothing more than timber licences and drilling sites, where value is not recognized unless it is monetized. Oblivious to context and blind to big-picture thinking, it analyzes, mechanizes, digitizes, and systematizes, while rejecting empathy and compassion as distorting influences. Lyric comprehension, in Zwicky’s view, offers an alternative to this way of thinking, and she provides a wide range of examples. Once upon a Time in the West documents how a narrow epistemological style has left Western thought blind to critical features of reality, and how the terrifying consequences of that blinkered vision are now beginning to unfold.

Virtual Crowds

Steps Toward Behavioral Realism

By: Mubbasir Kapadia,Nuria Pelechano,Jan Allbeck,Norm Badler

This volume presents novel computational models for representing digital humans and their interactions with other virtual characters and meaningful environments. In this context, we describe efficient algorithms to animate, control, and author human-like agents having their own set of unique capabilities, personalities, and desires. We begin with the lowest level of footstep determination to steer agents in collision-free paths. Steering choices are controlled by navigation in complex environments, including multi-domain planning with dynamically changing situations. Virtual agents are given perceptual capabilities analogous to those of real people, including sound perception, multi-sense attention, and understanding of environment semantics which affect their behavior choices. The roles and impacts of individual attributes, such as memory and personality are explored. The animation challenges of integrating a number of simultaneous behavior and movement demands on an agent are addressed through an open source software system. Finally, the creation of stories and narratives with groups of agents subject to planning and environmental constraints culminates the presentation.
