This volume contains those research papers presented at the Second International Conference on Tests and Proofs (TAP 2008) that were not included in the main conference proceedings. TAP was the second conference devoted to the convergence of proofs and tests. It combines ideas from both areas for the advancement of software quality. To prove the correctness of a program is to demonstrate, through impeccable mathematical techniques, that it has no bugs; to test a program is to run it with the expectation of discovering bugs. On the surface, the two techniques seem contradictory: if you have proved your program, it is fruitless to comb it for bugs; and if you are testing it, that is surely a sign that you have given up on any hope of proving its correctness. Accordingly, proofs and tests have, since the onset of software engineering research, been pursued by distinct communities using rather different techniques and tools. And yet the development of both approaches leads to the discovery of common issues and to the realization that each may need the other. The emergence of model checking has been one of the first signs that contradiction may yield to complementarity, but in the past few years an increasing number of research efforts have encountered the need for combining proofs and tests, dropping earlier dogmatic views of their incompatibility and taking instead the best of what each of these software engineering domains has to offer. The first TAP conference (held at ETH Zurich in February 2007) was an attempt to provide a forum for the cross-fertilization of ideas and approaches from the testing and proving communities. For the 2008 edition we found the Monash University Prato Centre near Florence to be an ideal place providing a stimulating environment. We wish to sincerely thank all the authors who submitted their work for consideration. And we would like to thank the Program Committee members as well as additional referees for their great effort and professional work in the review and selection process. Their names are listed on the following pages. In addition to the contributed papers, the program included three excellent keynote talks. We are grateful to Michael Hennell (LDRA Ltd., Cheshire, UK), Orna Kupferman (Hebrew University, Israel), and Elaine Weyuker (AT&T Labs Inc., USA) for accepting the invitation to address the conference. Two very interesting tutorials were part of TAP 2008: "Parameterized Unit Testing with Pex" (J. de Halleux, N. Tillmann) and "Integrating Verification and Testing of Object-Oriented Software" (C. Engel, C. Gladisch, V. Klebanov, and P. Rümmer). We would like to express our thanks to the tutorial presenters for their contribution. It was a team effort that made the conference so successful. We are grateful to the Conference Chair and the Steering Committee members for their support. And we particularly thank Christoph Gladisch, Beate Körner, and Philipp Rümmer for their hard work and help in making the conference a success. In addition, we gratefully acknowledge the generous support of Microsoft Research Redmond, who financed an invited speaker.
The University of Koblenz-Landau would like to apply for participation in the RoboCup Mixed Reality League in Suzhou, China 2008. Our team is composed of ten team members and two supervisors. All members are graduate students of Computational Visualistics. Our supervisors are Ph.D. candidates currently researching in the working groups of artificial intelligence and computer graphics.
Social networking platforms as creativity fostering systems: research model and exploratory study
(2008)
Social networking platforms are enabling users to create their own content, share this content with anyone they invite and organize connections with existing or new online contacts. Within these electronic environments users voluntarily add comments on virtual boards, distribute their search results or add information about their expertise areas to their social networking profiles and thereby share it with acquaintances, friends and increasingly even with colleagues in the corporate world. As a result, it is most likely that the underlying knowledge sharing processes result in many new and creative ideas. The objective of our research therefore is to understand if and how social social networking platforms can enforce creativity. In addition, we look at how these processes could be embedded within the organizational structures that influence innovative knowledge sharing behavior. The basis for our research is a framework which focuses on the relations between intrinsic motivation, creativity and social networking platforms. First results of our empirical investigation of a social software platform called "StudiVZ.net" proved that our two propositions are valid.
Probability propagation nets
(2008)
In der vorliegenden Arbeit wird eine Petri-Netz-Repräsentation für die Propagation von Wahrscheinlichkeiten und Evidenzen (Likelihoods) vorgestellt und auf probabilistische Horn-Abduktion sowie Fehlerbäume und Bayes-Netze angewendet. Diese sogenannten Wahrscheinlichkeits-Propagations-Netze (probability propagation nets) machen Propagations-Prozesse transparent, indem sie strukturelle und dynamische Aspekte in einer homogenen Darstellung vereinen. Anhand populärer Beispiele wird verdeutlicht, dass Wahrscheinlichkeits-Propagations-Netze die Propagations-Prozesse - besonders im Hinblick auf die Bayes-Netz-Algorithmik - anschaulich darstellen und gut nachvollziehbar machen, so dass sie sich für die Analyse und Diagnose probabilistischer Modelle eignen. Durch die Repräsentation von Fehlerbäumen mit Wahrscheinlichkeits-Propagations-Netzen können diese Vorzüge auf die Modellierung technischer Systeme übertragen werden.
Querying for meta knowledge
(2008)
The Semantic Web is based on accessing and reusing RDF data from many different sources, which one may assign different levels of authority and credibility. Existing Semantic Web query languages, like SPARQL, have targeted the retrieval, combination and reuse of facts, but have so far ignored all aspects of meta knowledge, such as origins, authorship, recency or certainty of data, to name but a few. In this paper, we present an original, generic, formalized and implemented approach for managing many dimensions of meta knowledge, like source, authorship, certainty and others. The approach re-uses existing RDF modeling possibilities in order to represent meta knowledge. Then, it extends SPARQL query processing in such a way that given a SPARQL query for data, one may request meta knowledge without modifying the query proper. Thus, our approach achieves highly flexible and automatically coordinated querying for data and meta knowledge, while completely separating the two areas of concern.
Die automatische Detektion der Lage und Ausrichtung von Unterwasser-Kabeln oder -Pipelines in Kamerabildern ermöglicht es, Unterwasserfahrzeuge autonome Kontrollfahrten durchführen zu lassen. Durch Pflanzenwuchs auf und in der Nähe von Kabeln bzw. Pipelines wird deren visuelle Erfassung jedoch erschwert: Die Bestimmug der Lage über die Detektion von Kanten mit anschließender Linien-Extraktion schlägt oft fehl. Probabilistische Ansätze sind hier den deterministischen überlegen. Durch die Modellierung von Wahrscheinlichkeiten kann trotz geringer Anzahl von extrahierten Merkmalen eine Aussage über den Zustand des Systems getroffen werden. Diese Arbeit stellt ein neues auf Partikelfiltern basierendes Tracking-System für die Verfolgung von Kabeln und Pipelines in Bildsequenzen vor. Umfangreiche Experimente auf realistischen Unterwasser-Videos zeigen die Robustheit und Performanz des gewählten Ansatzes sowie Vorteile gegenüber vorangegangenen Arbeiten.
Öffentliche elektronische Beschaffung (eProcurement), bzw. strategischer elektronischer Einkauf (eSourcing), sind mit hoher Wahrscheinlichkeit Thema sobald eGovernment Experten aufeinander treffen. So ist es nicht überraschend, dass eProcurement im aktuellen Aktionsplan der EU als "high-impact service" eingestuft wurde. Dies lässt sich zum Großteil durch den großen Einfluss vom öffentlichen Einkauf auf die Staatskasse erklären. So macht eProcurement in der Regel bis zu 20% des BIP aus und beherbergt somit ein enormes Einsparpotenzial. Dieses Potenzial liegt zum Teil im gemeinsamen Europäischen Wirtschaftsraum, da effizientes länderübergreifendes eSourcing neue Möglichkeiten für Einkäufer sowie Lieferanten eröffnen kann. Um diese Möglichkeiten ausschöpfen zu können, müssen Prozesse und Tools in der Lage sein, miteinander zu kommunizieren, sich aufeinander abzustimmen oder transferierbar sein. In einem Wort, sie müssen interoperabel sein. In vielen wichtigen Bereichen ist Interoperabilität sehr weit fortgeschritten, in anderen hingegen muss noch viel verändert werden. Daher ist es von wesentlicher Bedeutung Interoperabilitätsanforderungen zu definieren, sowie den aktuellen Forschungs- und Entwicklungsstand zu evaluieren.
Computers and especially computer networks have become an important part of our everyday life. Almost every device we use is equipped with a computer or microcontroller. Recent technology has even boosted this development by miniaturization of the size of microcontrollers. These are used to either process or collect data. Miniature senors may sense and collect huge amounts of information coming from nature, either from environment or from our own bodies. To process and distribute the data of these sensors, wireless sensor networks (WSN) have been developed in the last couple of years. Several microcontrollers are connected over a wireless connection and are able to collect, transmit and process data for various applications. Today, there are several WSN applications available, such as environment monitoring, rescue operations, habitat monitoring and smart home applications. The research group of Prof. Elaine Lawrence at the University of Technology, Sydney (UTS) is focusing on mobile health care with WSN. Small sensors are used to collect vital data. This data is sent over the network to be processed at a central device such as computer, laptop or handheld device. The research group has developed several prototypes of mobile health care. This thesis will deal with enhancing and improving the latest prototype based on CodeBlue, a hardware and software framework for medical care.
