Todays organizations are socio-technical entities, and interactions have significant impact on their success. Around 50% of the work in the US is knowledge work, and other countries show a similar tendency. Compliance monitoring of course can only cover processes and tasks that are modeled or documented somehow. Therefore, today it faces the problem that(More)
Knowledge workers already face a broad range of tools to support their work, e.g. adaptive case management systems, tailored information systems, groupware, and other (process) support systems. Case data is scattered across many systems, and the overlapping structured, semi-structured, and ad-hoc processes involved further impede keeping track of related(More)
Ground nodes receive the signals transmitted by the mobile nodes. They are also sensor nodes that run on batteries. Currently, all their detections are forwarded to a central base station, where a localization method integrates them into a position estimation for each bat [NKD15]. The base station is a standard computer with sufficient power and energy. In(More)
Many interesting applications of continuous-query processing are concerned with pattern matching or complex temporal aggregation of events. Real-world queries that rely on these operations are difficult to implement in current stream-processing systems. The reason seems to be a gap between two types of existing query languages: Some languages (e. g. CQL)(More)
In the medical domain, data quality is very important. Since requirements and data change frequently, continuous and sustainable monitoring and improvement of data quality is necessary. Working together with managers of medical centers, we developed an architecture for a data quality monitoring system. The architecture enables domain experts to adapt the(More)
