Inexpensive wearable sensors are well-suited for the automatic recognition of many activities occuring in everyday life. But what about fast and involved movements such as those occuring in athletic sports? We tackle this question by studying the feasibility of using body-worn gyroscopes and acceleration sensors to recognize Tai Chi movements. To this end,(More)
Home and automation are not natural partners--one <i>homey</i> and the other cold. Most current automation in the home is packaged in the form of appliances. To better understand the current reality and possible future of living with other types of domestic technology, we went out into the field to conduct need finding interviews among people who have(More)
By incorporating temporal effects into the geographically weighted regression (GWR) model, an extended GWR model, geographically and temporally weighted regression (GTWR), has been developed to deal with both spatial and temporal nonstationarity simultaneously in real estate market data. Unlike the standard GWR model, GTWR integrates both temporal and(More)
The evidence presented, together with the lack of solid evidence for a specific receptor site, strongly suggests that taurine does not act as a traditional neurotransmitter in the CNS. In fact, the properties seen to be governing its efflux from both glial cells and neurons argue strongly in favor of a primary role in volume regulation. However, subsequent(More)

We present a mobile, multimedia system based on a network of body worn motion sensors, a wearable computer and a visualization engine that is used to produce a visual enhancement of Butoh dance performance. The core of the system is a novel motion classification scheme that allows us to capture the emotion expressed by the dancer during the performance and(More)
The focus of this research is in the definition of programmable expert Personal Health Systems (PHS) to monitor patients affected by chronic diseases using agent oriented programming and mobile computing to represent the interactions happening amongst the components of the system. The paper also discusses issues of knowledge representation within the(More)
A yellow fever epidemic erupted in Guinea in September, 2000. From Sept 4, 2000, to Jan 7, 2001, 688 instances of the disease and 225 deaths were reported. The diagnosis was laboratory confirmed by IgM detection in more than 40 patients. A mass vaccination campaign was limited by insufficient international stocks. After the epidemic in Guinea, the(More)
