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)
The State of Minnesota has under way its Toward Zero Deaths (TZD) initiative, the goal of which is to eliminate fatal traffic crashes. This is a daunting task, and with limited financial resources, optimal strategies that provide the greatest benefit for a given cost have to be utilized if the goal of TZD is to be met. This report reviews both(More)
The provision of next generation mobile wireless access necessitates the coexistence of legacy cellular systems and new air interface technologies in cooperative heterogeneous environments. These multi-system environments consist of a number of radio access networks with different radio access technologies such as WiMax, GERAN, UMTS and WLAN. Joint radio(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)
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)
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)

A study was designed to determine the interactions, both clinical and pharmacokinetic, between methadone and lopinavir-ritonavir. Results demonstrated a 36% reduction in the methadone area under the plasma concentration-time curve after the introduction of lopinavir-ritonavir, with no coincident symptoms of opioid withdrawal and no requirement for methadone(More)
