The recent rise of smart applications has drawn interest to logical reasoning over data streams. Different query languages and stream processing/reasoning engines were proposed. However, due to a lack of theoretical foundations, the expressivity and semantics of these diverse approaches were only informally discussed. Towards clear specifications and means for analytic study, a formal framework...

The rapidly growing market of industrial and automotive vision systems demands for image sensors with very high dynamic ranges of more than 100dB. State of the art linear imagers are not capable of delivering this signal range at standard video speeds while sensors with logarithmic signal compression suffer from high fixed pattern noise, low contrast and excessive temperature drift. The newly d...

Labdog is a novel web technology designed to promote learning in and around the teaching laboratory. During a laboratory session, Labdog offers functionality similar to a Classroom Response System (CRS), e.g. ‘clickers’ or ‘zappers’. Labdog focuses on a different environment: the teaching laboratory – and can therefore be referred to as a Laboratory Response System (LaRS). Results from piloting...

We analyse issues of provider incentives and the actual burden sharing between government, enterprises and people. We further aim to identify a number of current problems and link these to a discussion of future challenges in the form of an aging population, increased privatizatio...
