With the increase in applications for sensor networks, data manipulation and representation have become a crucial component of sensor networks. This chapter explores an implementation to process and interpret the data gathered by sensor networks. In a project supported by SensIT program at DARPA, we have built wireless sensor networks deployed to monitor rare plants or other endangered species....

in this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. we extract the information function ofan ergodic dynamical system (x,t) from the relative information of t fromthe view point of observer χx, where x denotes the base space of the system.we also generalize the inv...

pacs is used as a way to store images and matches well with the workflow in the radiology department and can spread to other parts of hospital. integration with other pacs and other hospital systems like radiology information system (ris), hospital information system (his), and electronic patient records has been completely done, but there are still problems. pacs also provide good conditions f...
