Many applications or algorithms in sensor networks require positional information of the sensors. Most approaches for this problem rely either on distances between communicating node pairs or on local angular information. Although distance-based methods are widespread, we here present a technique for direction-based localization in general networks. Whereas Bruck et al. proved that the correspo...

This paper addresses the issue of cluster labeling and presents a method for assigning labels by using concepts in a machinereadable dictionary. We assume that salient terms in the cluster content have the same hypernym because hypernymic semantic relation represents a generalization that goes from specific to generic. Our experimental results reveal that hypernymic semantic relations can be ex...

To retrieve multimedia contents by their meaning , it is necessary to use not only the contents of distinct media, such as image or language, but also a certain semantic relation holding between them. For this purpose, in this paper, we propose a method to find coreferences between human names in the article of newspaper and human faces in the accompanying photograph. The method we proposed is ...

Point source spectrophotometric ("single-point") light curves of Earth-like planets contain a surprising amount information about the spatial features those worlds. Spatially resolving these is important for assessing time-varying surface and existence an atmosphere, which in turn critical to life on Earth significant determining habitability exoplanets. Given that only celestial body confirmed...

Introduction Traditional architectures which consist of a single processor, a small main memory, and secondary memory devices (e.g. disks), are gradually being replaced by multiprocessor multi-disk architec­ tures with a relatively large main m~mory. The processors either reside in the same site and communicate via the shared memory, or reside in different sites and communicate via a local netw...
