Semantic discovery and reuse of business process patterns
Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
Foundations of realistic rendering : a mathematical approach
Die vorliegende Dissertation ist keine gewöhnliche Abhandlung, sondern sie ist als Lehrbuch
zum realistischen Rendering fĂŒr Studenten im zweiten Studienabschnitt, sowie Forscher
und am Thema Interessierte konzipiert.
Aus mathematischer Sicht versteht man unter realistischem Rendering das Lösen der
stationÀren Lichttransportgleichung, einer komplizierten Fredholm Integralgleichung der
2tenArt, deren exakte Lösung, wenn ĂŒberhaupt berechenbar, nur in einem unendlich-
dimensionalen Funktionenraum existiert. WĂ€hrend in den existierenden BĂŒchern, die sich mit globaler Beleuchtungstheorie beschĂ€ftigen, vorwiegend die praktische Implementierung von LösungsansĂ€tzen im Vordergrund steht, sind wir eher daran interessiert, den Leser mit den mathematischen Hilfsmitteln vertraut zu machen, mit welchen das globale Beleuchtungsproblem streng mathematisch formuliert und letzendlich auch gelöst werden kann.
Neue, effzientere und elegantere Algorithmen zur Berechnung zumindest approxima-
tiver Lösungen der Lichttransportgleichung und ihrer unterschiedlichen Varianten können
nur im Kontext mit einem vertieften VerstÀndnis der Lichttransportgleichung entwickelt
werden. Da die Probleme des realistischen Renderings tief in verschiedenen mathematis-
chen Disziplinen verwurzelt sind, setzt das vollstÀndige VerstÀndnis des globalen Beleuch-
tungsproblems Kenntnisse aus verschiedenen Bereichen der Mathematik voraus. Als zen-
trale Konzepte kristallisieren sich dabei Prinzipien der Funktionalanalysis, der Theorie der
Integralgleichungen, der MaĂ- und Integrationstheorie sowie der Wahrscheinlichkeitstheo-
rie heraus.
Wir haben uns zum Ziel gesetzt, dieses KnÀuel an mathematischen Konzepten zu
entflechten, sie fĂŒr Studenten verstĂ€ndlich darzustellen und ihnen bei Bedarf und je nach
speziellem Interesse erschöpfend Auskunft zu geben.The available doctoral thesis is not a usual paper but it is conceived as a text book for
realistic rendering, made for students in upper courses, as well as for researchers and
interested people.
From mathematical point of view, realistic rendering means solving the stationary light transport equation, a complicated Fredholm Integral equation of 2nd kind. Its exact
solution exists|if possible at all|in an infinite dimensional functional space. Whereas practical implementation of approaches for solving problems are in the center of attentionin the existing textbooks that treat global illumination theory, we are more interested in familiarizing our reader with the mathematical tools which permit them to formulate the global illumination problem in accordance with strong mathematical principles and last but not least to solve it.
New, more eficient and more elegant algorithms to calculate approximate solutions for
the light transport equation and their different variants must be developed in the context
of deep and complete understanding of the light transport equation. As the problems
of realistic rendering are deeply rooted in different mathematical disciplines, there must
precede the complete comprehension of all those areas. There are evolving principles of
functional analysis, theory of integral equations, measure and integration theory as well
as probability theory.
We have set ourselves the target to remerge this bundle of fluff of mathematical
concepts and principles, to represent them to the students in an understandable manner,
and to give them, if required, exhaustive information
Sustainable Poetry: Four American Ecopoets
Focusing on the work of A.R. Ammons, Wendell Berry, W.S. Merwin, and Gary Snyder, author Leonard Scigaj shows that just as a sustainable society does not depreciate its resource base, so a sustainable poetry does not restrict interest to language. Over the past thirty years many poets have shown an increasing sensitivity to ecological thinking. But critics trained in poststructuralist language theory often fail to explore the substance of ecopoetry. Scigaj is the first to define ecopoetry as separate and distinct from nature or environmental poetry, marked by its concern with balancing the interests of human beings with the needs of nature. Just as science learned that the earth was not the center of the universe, ecopoetry insists on the recognition that humans are not at the center of the natural world.

Anymals, Poems, Empathy.:A Zoopoetical Study
Summary A vast body of research addresses the relationships between empathy and novels figuring human protagonists, and the notion that novel reading as a kind of âempathy trainingâ meets little skepticism. As the saying goes, readers can live a thousand lives in the minds of the characters in the novels they read. How different the case when the protagonists are anymals instead of humans. This study focuses on zoopoetry to explore the intricate relation between anymals, poems, and empathy. It addresses the abyss between the anymal and the human, whether an abyss of knowledge or of phenomenal experience, to argue that poets who write about anymals employ âzoopoetical toolsâ to bridge the gap between the two worlds. They employ an array of traditional poetic tools such as rhythm and metaphor, but they also draw from a previously unnamed zoopoetical lexicon to illustrate how the assumed abyss between the anymal and the human is in fact based on speciesism and Cartesian dualism. In his article âWhat Is It Like to Be a Bat?â (1974), the philosopher Thomas Nagel provocatively argues that we are unable to know what it is to feel bat-like. We might be able to imagine to a certain extent what it is to fly around and catch insects in our mouths, he writes, but then we only know what it is like for us to behave like a bat, whereas we can never know what it is like for a bat to be a bat. In trying to imagine what a bat experiences, we stumble on a line we can never cross, between our own subjective worlds and the phenomenal experience of the bat. Researchers in both literary studies and biology often invoke Nagelâs example and presume a skeptical stance concerning the knowability and envisionability of the phenomenal experience of anymal others. In this vein, Jenny Diski writes that there is âan abyss of knowledge that we simply canât crossâ (73). Three central oppositions emerge from speciecism and Cartesian dualism to complicate explorations of zoopoetical anymals: anthropocentrism versus anymals as themselves; projectivism versus empathy or sympathetic identification; and anymals inside a text versus anymals outside a text. Note that the tension in these oppositions is less felt when human subjects receive poetic attention. Zoopoetical anymals, however, seem to be inevitably anthropomorphised by poets and readers alike. As a result, empathy seems to become an unattainable ideal; with whom would we be empathising? In this study I argue, however, that many of these assumptions about anymal minds are based upon Cartesian dualism. This study, therefore, is driven by two central questions that counter these assumptions. In what ways does zoopoetry confront and unsettle Cartesian dualism? How do instances of perspective shift and empathy evoked through zoopoetry contribute to the empathy debate? These questions are not straightforwardly answered. Instead, the chapters show a hermeneutical to-and-fro movement between the poems, philosophical ideas, and the topic of empathy
