Sensor networks are a major new area of research. Some sensor applications, such as video surveillance, will need to be tethered for reasons of bandwidth and power requirements. T...
It is well known that optimal server placement is NP-hard. We present an approximate model for the case when both clients and servers are dense, and propose a simple server alloca...
A drawback of the commonly used single source computed tomography systems (CT) is that different materials might show very similar attenuation at any selected radiation energy. How...
