Recently, there has been a significant growth in pervasive computing and ubiquitous sensing which strives to develop and deploy sensing technology all around us. We are also seeing the emergence of applications such as environmental and personal health monitoring to leverage data from a physical world. Most of the developments in this area have been(More)
Personal Health (pHealth) sensor networks are generally used to monitor the well being of both athletes and the general public to inform health specialists of future and often serious ailments. The problem facing these domain experts is the scale and quality of data they must search in order to extract meaningful results. By using peer-to-peer sensor(More)
We investigated the role of oropharyngeal and postingestional stimulation in the control of the intake of water and NaCl solutions by testing water-deprived rats under real- and sham-drinking conditions with water, 0.150, 0.225, and 0.300 M NaCl solutions. A series of real-drinking tests was given until intake stabilized followed by a series of(More)
The performance of a compact K-band power amplifier MMIC fabricated in standard 6-inch 0.15-mum GaAs power PHEMT technology is reported. The circuit features on-chip ESD protection including input short-circuit stub, dual capacitors at RF ports and high-current diode arrays on each gate pad. Occupying less than 3 mm<sup>2</sup>, this 3-stage power amplifier(More)
55 When dealing with sensor data for a team sport, it is often useful to be able to query across multiple sensors and thus to be able to compare data from several players for any given moment in time. In order to do this, the data from all sensors must be synchronized so that the start time of the game or activity can be identified in the data from each(More)
1 Background New sensing technologies and the decreasing cost of Information and Communication Technologies (ICTs) make possible the development of electronic Health (eHealth) monitoring systems. The challenges of such systems include the representation of data extracted from various sensor devices by knowledge workers through semantic enrichment and(More)
We describe at the microstructural level the impact of unconditioned and conditioned negative feedback on the licking behavior of the rat. Six groups of rats were trained to ingest one of six different dilutions of sweetened milk (0.5:1, 1:1, 2:1, 4;1, 8:1, and 16:1, water to milk ratios) under real feeding conditions until intake was stable. Then they were(More)
