This quantity is dedicated to the tenth Anniversary Colloquium of UNU/IIST, the foreign Institute for software program expertise of the United international locations collage, in addition to to the reminiscence of Armando Haeberer, who passed on to the great beyond whereas he was once engaged on the instruction of this booklet in February 2003.

The quantity begins with a distinct paper via Tom Maibaum recollecting Armando Haeberer's existence and paintings. the second one half offers paintings performed by means of individuals of UNU/IIST in addition to a paper at the background of the institute. the following topical sections current key contributions through prime researchers and hence examine the cutting-edge in software program engineering and its engineering and medical ideas, from types to software program, real-time platforms, and verification. All in all, the publication is a distinct survey of the ability and power of formal tools in software program engineering.

Download Program Development in Computational Logic: A Decade of by Maurice Bruynooghe, Kung-Kiu Lau PDF

By Maurice Bruynooghe, Kung-Kiu Lau

1 The 10th anniversary of the LOPSTR symposium supplied the inducement for this quantity. LOPSTR begun in 1991 as a workshop on good judgment software synthesis and transformation, yet later it broadened its scope to logic-based software improvement typically, that's, application improvement in computational good judgment, and consequently the name of this quantity. The motivating strength at the back of LOPSTR has been the idea that declarative paradigms resembling good judgment programming are higher suited for software improvement projects than conventional non-declarative ones resembling the central paradigm. Speci?cation, synthesis, transformation or specialization, research, debugging and veri?cation can all accept logical foundations, hence delivering a unifying framework for the full improvement technique. long ago 10 years or so, the sort of theoretical framework has certainly began to emerge. Even instruments were carried out for research, veri?cation and speci- ization. However,itisfairtosaythatsofarthefocushaslargelybeenonprogrammi- in-the-small. So the longer term problem is to use or expand those suggestions to programming-in-the-large, in an effort to take on software program engineering within the genuine international. Returning to this quantity, our objective is to offer a set of papers that re?ect signi?cant learn e?orts over the last 10 years. those papers disguise the wholedevelopmentprocess:speci?cation,synthesis,analysis,transformationand specialization, in addition to semantics and systems.

Download Automatische Komplexitätsanalyse funktionaler Programme by Wolf Zimmermann PDF

By Wolf Zimmermann

Es gibt im Bereich der Softwaretechnik viele Werkzeuge, die den Programmentwicklungsprozeß unterstützen. Sie stellen die Korrektheit der Implementierung sicher, nicht aber ihre Effizienz. Die vorliegende Arbeit führt daher eine Methode ein, die es erlaubt, die Zeitkomplexität funktionaler Programme automatisch zu ermitteln. Die Grundidee dieser Methode besteht darin, ein funktionales Programm in ein process von Rekurrenzgleichungen zu übersetzen, dessen Lösung das Zeitverhalten des Programms angibt. Durch Einführung von bedingten Rekurrenzen und Rekurrenzfamilien ist es möglich, obere und untere Schranken für die Zeitkomplexität zu finden. Um die mittlere Zeitkomplexität zu bestimmen, müssen Wahrscheinlichkeiten dafür berechnet werden, daß im Programm vorkommende Bedingungen wahr bzw. falsch werden. Diese Wahrscheinlichkeiten werden anhand einer probabilistischen Semantik des Programms berechnet. Um möglichst genaue Schranken für die Zeitkomplexität zu erhalten, muß eine Abhängigkeitsanalyse durchgeführt werden. Dies ermöglicht eine genaue examine von Divide-and-Conquer-Programmen.

By Kim Marriott, Bernd Meyer

Kim Marriott Bernd Meyer verbal exchange is without doubt one of the hallmarks of people. once we give some thought to hu­ guy verbal exchange, most folk first give some thought to spoken and written lan­ guages. those are comparable in that symbols within the language are encountered and processed sequentially, both temporally as they're spoken or as char­ acters are learn throughout a web page. although, now not all human conversation is sequential in nature. vital elements of human conversation are visible languages, resembling maps or diagrams. In those languages the elemental symbols are usually not encountered sequentially yet relatively visible jointly at a look. visible languages are ubiquitous in human cultures, starting from tradi­ tional work of vital Australian aborigines that are, partially, maps of the nation-state to an architect's layout of a brand new development. visible languages were hired from earliest pre-history to the current and are utilized in virtually each human recreation. They hide the full spectrum of human expression starting from wonderful artwork, akin to an summary expressionist's deepest language, to specific technical conversation utilizing conscientiously outlined no­ tation, comparable to musical notation, mathematical notation, or road maps. a few visible languages, corresponding to signal languages utilized by the deaf group, replacement spoken language totally. certainly, signal languages, for instance American signal Language, are a very fascinating example of visible verbal exchange, given that they use 3-dimensional spatial preparations of symptoms together with their sequential temporal order to represent meaning.

Download Parallel Machines: Parallel Machine Languages: The Emergence by Robert A. Iannucci PDF

By Robert A. Iannucci

It is universally authorised this present day that parallel processing is right here to stick yet that software program for parallel machines remains to be tough to strengthen. despite the fact that, there's little attractiveness of the truth that adjustments in processor structure can considerably ease the advance of software program. within the seventies the provision of processors which may deal with a wide identify house at once, eradicated the matter of brand administration at one point and lead the way for the regimen improvement of huge courses. equally, this day, processor architectures that could facilitate reasonable synchronization and supply a world deal with house can simplify compiler improvement for parallel machines. If the price of synchronization is still excessive, the professional­ gramming of parallel machines will stay considerably much less summary than programming sequential machines. during this monograph Bob Iannucci provides the layout and research of an structure that may be a greater construction block for parallel machines than any von Neumann processor. there's one other very fascinating motivation in the back of this paintings. it truly is rooted within the lengthy and venerable background of dataflow graphs as a formalism for ex­ urgent parallel computation. the sphere has bloomed on account that 1974, whilst Dennis and Misunas proposed a very novel structure utilizing dataflow graphs because the parallel computing device language. the newness and magnificence of dataflow architectures has, despite the fact that, additionally stored us from asking the genuine query: "What can dataflow architectures purchase us that von Neumann ar­ chitectures can't?" within the following I clarify in a around approximately method how Bob and that i arrived at this question.
