In many data streaming applications, streams may contain data tuples that are either redundant , repetitive, or that are not " interesting " to any of the standing continuous queries. Processing such tuples may waste system resources without producing useful answers. To the contrary, some other tuples can be categorized as promising. This paper proposes(More)
A low cost dataglove system is developed by designing a glove equipped with Force Sensing Resistor (FSR) on to the thumb, index and middle finger, named as GloveMAP. The system involves the finger movements with some of grasping activities to investigate the force exerted on the fingertips during grasping five different shapes of objects with same weight.(More)
A wired glove system is developed by designing a low cost glove which has the similar function with the conventional dataglove and has been named as GloveMAP. The system involves the finger movements with some of grasping activities to investigate the force exerted on the fingertips during grasping a cylinder with different weight. Force sensing resistors(More)
A phenomenon appears in a sensor network when a group of sensors continuously generate a similar behavior over a period of time. PhenomenaBases (or databases of phenomena) are equipped with Phenomena Detection and Tracking (PDT) techniques that continuously run in the background of a sensor database system to detect and track phenomena. The process of(More)
Scalability and energy management issues are crucial for sensor network databases. In this paper, we introduce the Sharing and PArtitioning of Stream Spectrum (SPASS) protocol as a new approach to provide scalability with respect to the number of sensors and to manage the power consumption efficiently. The spectrum of a sensor is the range/distribution of(More)
