As reported earlier, our experiments demonstrate that very high information transfer rates can be achieved using the readiness potential (RP) when predicting the laterality of upcoming left-versus right-hand movements in healthy subjects. A more recent study showed that the RP similarily accompanies phantom movements in arm amputees, but the signal strength decreases with longer loss of the limb. In a complementary approach, oscillatory features are used to discriminate imagined movements (left hand versus right hand versus foot). In a recent feedback study with six healthy subjects with no or very little experience with BCI control, three subjects achieved an information transfer rate above 35 bits per minute (bpm), and further two subjects above 24 and 15 bpm, while one subject could not achieve any BCI control. These results are encouraging for an EEG-based BCI system in untrained subjects that is independent of peripheral nervous system activity and does not rely on evoked potentials even when compared to results with very well-trained subjects operating other BCI systems}, language = {en} } @article{WilligMitschke2006, author = {Willig, Andreas and Mitschke, Robert}, title = {Results of bit error measurements with sensor nodes and casuistic consequences for design of energy-efficient error control schemes}, isbn = {978-3-540-32158-3}, year = {2006}, abstract = {For the proper design of energy-efficient error control schemes some insight into channel error patterns is needed.

P.}, title = {Conformance testing: Measuring the fit and appropriateness of event logs and process models}, year = {2006}, abstract = {Most information systems log events (e.g., transaction logs, audit traits) to audit and monitor the processes they support. At the same time, many of these processes have been explicitly modeled. For example, SAP R/3 logs events in transaction logs and there are EPCs (Event-driven Process Chains) describing the so-called reference models. These reference models describe how the system should be used. The coexistence of event logs and process models raises an interesting question: "Does the event log conform to the process model and vice versa?". This paper demonstrates that there is not a simple answer to this question. To tackle the problem, we distinguish two dimensions of conformance: fitness (the event log may be the result of the process modeled) and appropriateness (the model is a likely candidate from a structural and behavioral point of view). Different metrics have been defined and a Conformance Checker has been implemented within the ProM Framework}, language = {en} } @article{GerbserSchaub2006, author = {Gerbser, Martin and Schaub, Torsten H.}, title = {Tableau calculi for answer set programming}, issn = {0302-9743}, doi = {10.1007/11799573}, year = {2006}, language = {en} } @article{Konczak2006, author = {Konczak, Kathrin}, title = {Voting Theory in Answer Set Programming}, year = {2006}, language = {en} } @article{AngerGebserJanhunenetal.2006, author = {Anger, Christian and Gebser, Martin and Janhunen, Tomi and Schaub, Torsten H.}, title = {What's a head without a body?}, year = {2006}, language = {en} } @article{GerbserLeeLierler2006, author = {Gerbser, Martin and Lee, Joohyung and Lierler, Yuliya}, title = {Elementary sets for logic programs}, isbn = {978-1-57735-281-5}, year = {2006}, language = {en} } @article{GerbserSchaub2006, author = {Gerbser, Martin and Schaub, Torsten H.}, title = {Characterizing (ASP) inferences by unit propagation}, year = {2006}, language = {en} } @article{Konczak2006, author = {Konczak, Kathrin}, title = {Weak order equivalence for Logic Programs with Prefernces}, year = {2006}, language = {en} }
