Several next-generation radio telescopes, now in the planning stages, are based on phased-array technology. One reason for this is to make use of adaptive nulling techniques to combat radio frequency interference, which is a growing problem for radio astronomy. This paper presents a low-complexity approach to interference nulling which is suitable for use in such systems. The approach uses subs...

The increasing functionality that handheld devices have come to incorporate at lower prices make them powerful candidates for various kinds of location-aware systems and services. In this work, we describe the innards of Uhuru, an RF based in-building location tracking system that we have developed and deployed on a mobile device. Our work seeks to build upon and extend previous work in this fi...

multiple people detection and tracking is a challenging task in real-world crowded scenes. in this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. we have detected objects with deformable part models and a visual background extractor. in the tracking phase we have used a combination of support vector machine (svm) person-specific classifie...

Predation is a major source of mortality for many avian species. Species that face more predators, and those with less effective anti-predator responses, are presumably likely to die from predation over time. rate, as measure susceptibility predation, difficult in the field. Radio-tracking studies, however, allow researchers determine time cause death marked individuals, making it possible esti...

The proliferation of technologically advanced and mobile devices poses risks to public safety security. These threats can be mitigated by systems equipped perform timely identification tracking their operators. In pursuit these capabilities, we propose an automated sensing platform designed specifically for multiple, radio frequency (RF) targets. There are a number challenges involved with mult...
