Pulp exploits the efficiency of push approaches, while limiting redundant messages and therefore imposing a low overhead, as pull protocols do. Pulp leverages the dissemination of multiple messages from diverse sources: by exploiting the push phase of messages to transmit information about other disseminations, Pulp enables an efficient pulling of other messages, which themselves help in turn with the dissemination of pending messages. We deployed Pulp on a cluster and on PlanetLab. Our results demonstrate that Pulp achieves an appealing trade-off between coverage, message redundancy, and propagation delay.

Analyzing Software Architectures: A Semantic Model
View more presentations from Förderverein Technische Fakultät.
Abstract: Ideally, we want to think of the software architecture phase of a product lifecycle as the phase when the non functional attributes of the product are determined; a disciplined approach to software architecture consists in identifying the non functional attributes that we want to optimize for the product at hand, and architecting the system accordingly, perhaps at the expense of other desirable but less important attributes. Yet, most current architectural description languages offer no means to represent non functional attributes of architectural components, and (to the best of our language) none offer any means to (automatically) reason about them. In this talk, we discuss our work in defining an architectural description language as an extension of ACME, and in designing a compiler for this language that enables us to compute system-wide attributes from component-level attributes. The talk concludes with a demo of the tool on a sample software architecture.

Selbstorganisierende Synchronisation
30. Mai 2012
Abstract: Communication and computer networks interconnect an increasing number and diversity of entities, such as mobile devices, sensors, wearable computers, and embedded systems. This trend poses new challenges to the design and operation of networking algorithms and protocols. In particular, the increased system dynamics requires adaptability, distributed operation, and autoconfiguration. One approach to these challenges is to increase the level of self-organization in networks, i.e. to accomplish an intended overall system behavior from local interactions between the individual entities.
In this talk, I focus on a specific aspect of self-organization in networks, namely on self-organized synchronization, as required for medium access, scheduling of sleep phases, and collaborative sensing, to give some examples. We illustrate some synchronization phenomena occurring in nature, explain the theory of pulse-coupled oscillators, and finally present a synchronization solution that has been developed for wireless networks.
Keywords: Selbstorganisation, Synchronisation, Gekoppelte Oszillatoren, Dynamische Systeme, Vernetzte Systeme

His doctoral thesis on mobility modeling, connectivity, and adaptive clustering in wireless ad hoc networks was awarded the Dr.-Ing (summa cum laude) degree in 2004. Before becoming a professor, Christian was a senior researcher at DoCoMo Euro-Labs for two years, doing research on medium access and topology aspects of ad hoc networks.
Christian and his team work on the design, modeling, and analysis of future networked communication systems, with a focus on mobile and wireless networking. Major expertise is on algorithms and protocols, stochastic modeling aspects, network theory, and architectures. Current projects address cooperative relaying, self-organized synchronization, and collaborative microdrones. Christian’s teaching portfolio includes various graduate courses on mobile networks and an undergraduate course on electromagnetism.
The publication record includes over 20 articles in journals, magazines, and books, and about 70 papers in refereed conference proceedings. Two of his publications received best paper awards at the IEEE Vehicular Technology Conference, and another one the 2004 outstanding paper award from the German Informationstechnische Gesellschaft (ITG). He also co-authored the Wiley textbook ‚GSM – Architecture, protocols and services.‘ His current h-index, being a measure for the visibility and impact of publications, is 29.

Interaction in “off-screen space”: design possibilities and challenges
29. Mai 2012
Abstract: Many workspaces extend beyond the user’s available viewport, particularly on mobile devices with small screens. Scrolling, panning and zooming are commonly used interaction techniques to manipulate the content of the viewport, but hardware innovations are enabling new forms of interaction. In particular, range sensors and similar technology have recently been added to devices to support interaction in the surrounding “off-screen” space. This talk will sketch possible applications and usage scenarios for off-screen interaction, discuss the human factors involved when interaction is moved into off-screen space, and present the design possibilities and challenges currently investigated by the Interactive Systems research group.
Zur Person: Dr. David Ahlström is a Computer Scientist with interests in developing interactive techniques and interfaces. His current research is focused on modeling and empirically measuring human performance with interactive systems with the aim to understand human factors in computer use. Ahlström received his M.Sc. degree in Computer and Systems Sciences from Stockholm University, Sweden, and his Ph.D. in Computer Science from Klagenfurt University. After that he received an eighteen-months Erwin-Schrödinger-scholarship from The Austrian Science Fund and joined the Computer Science and Software Engineering department at the University of Canterbury in Christchurch, New Zealand. Since 2010 he is back in Klagenfurt and works as an assistant professor in the Interactive Systems Group at the Department of Informatics Systems.

FASTEST: Test Case Generation from Z Specifications
View more presentations from Förderverein Technische Fakultät.
Abstract
Fastest is a tool that assist software engineers in generating test cases from Z specifications. It provides tool support for a method of model-based testing know as the Test Template Framework. The tool reads a Z specification written in LaTeX markup and waits for commands from the user. Users can apply testing tactics to partition the input space of Z operations thus creating testing trees. Later they can prune these trees to eliminate unsatisfiable test specifications. In a third step, a satisfiability algorithm can be run to find a test case for each leaf in a testing tree. Finally, it is possible to refine these test cases into programs to test the implementation of the Z specification. In this talk I will show how Fastest works on some toy examples and our current research efforts.

A Conceptual-Modeling Approach to Data Extraction
9. Mai 2012
Abstract: For more than a decade we have been studying ways that conceptual modeling can improve our ability to extract semantic data from unstructured and semi-structured information sources such as web pages and historical documents. We start with a data-extraction ontology that comprises a conceptual model together with data frames describing concepts of interest that may be found in an information source. Data-extraction ontologies provide significant advantages over traditional extraction techniques because they give relatively high precision and recall and are robust to changes in the information source structure. However, these benefits come at a price: extraction ontologies require significant expertise to construct, and they apply to a relatively narrow domain of interest. In this lecture I will review our past contributions with a special emphasis on the research techniques we have applied, and I will also describe current areas of research and directions for future experimentation.
