Although invasive measurement of intracranial pressure (ICP) involving high-resolution waveform analysis allows assessment of intracranial compliance (ICC), it is only feasible in a few selected neurosurgical conditions. Intracranial compliance can be assessed using the high-frequency centroid (HFC), which is the power-weighted mean frequency within the 4(More)
Ambient notifications can support people in their daily activities, providing courses of action and relevant information in context. A key aspect of ambient notifications is the unobtrusive provision of information, embedded into the users' environment.

The world's population is aging, and this shift in demographics will place a high burden on the world's healthcare systems. Smart technology provides a potential method of addressing the demands of these changing demographics. In this paper, we describe the design for a smart calendar that supports elderly people in their daily tasks and activities with the(More)
The phototrophic bacterium Rhodobacter capsulatus photoreduces 2,4-dinitrophenol to 2-amino-4-nitrophenol, which is further metabolized by an aerobic pathway that is also light-dependent. The catabolism of 2-amino-4-nitrophenol requires O2 and the presence of alternative carbon (C) and nitrogen (N) sources, preferably acetate and ammonium. Rhodobacter(More)
