In this paper we present an energy efficient framework for processing spatial alarms on mobile clients, while maintaining low computation and storage costs. Our approach to spatia...
This paper investigates the design and implementation of mobile computations in Java. We discuss various issues encountered while building a Java library that allows active objects...
When we communicate with others in a most primitive way like face-to-face conversation, we normally gather at a common physical place. This physical constraint has been recognized ...
Abstract— In human-robot communication it is often important to relate robot sensor readings to concepts used by humans. We suggest to use a virtual sensor (one or several physic...
