The wireless market of the future will demand inexpensive hardware, expandability, interoperability, and the implementation of advanced signal processing functions—i.e. a software radio. Configurable computing machines are often ideal software radio platforms. In particular, the Stallion reconfigurable processor's efficient hardware reuse and scalability fulfill these radio's demands. The advan...

Natal dispersal in a vagile carnivore, the American marten (Martes americana), was studied by comparing radio-tracking data and microsatellite genetic structure in two populations occupying contrasting habitats. The genetic differentiation determined among groups of individuals using F(ST) indices appeared to be weak in both landscapes, and showed no increase with geographical distance. Genetic...

Superpositional sensor model can characterize the observations in many different applications such as radio frequency tomography, acoustic sensor network based tracking and wireless communications. In this paper we present two filters based on the random finite set (RFS) theory the multi-Bernoulli filter and its variant the hybrid multi-Bernoulli CPHD filter for superpositional sensors. We prov...

Validation studies of current GPS radio occultation experiments using meteorological analyses consistently report on a negative refractivity bias in the lower troposphere. It is shown that refractivity profiles obtained from Doppler-inverted bending angle profiles not only deviate significantly within zones of multipath propagation but also depend on the selected end point of the occultation si...

Radio frequency (RF) sensor networks are wireless sensor networks (WSNs) which use only the received signal strength (RSS) to perform tasks such as device-free localization (DFL) and tracking of individuals. In these systems, people to be located do not participate in the localization effort by carrying any radio device or sensor. Instead, a static deployed wireless network measures RSS on its ...

In this paper we address the problem of localizing, tracking and navigating mobile nodes associated to operators acting in a fixed wireless sensor network (WSN) using only RF information. We propose two alternative and somehow complementary strategies: the first one is based on an empirical map of the Radio Signal Strength (RSS) distribution generated by the WSN and on the stochastic model of t...

Radio-interferometric ranging is a novel technique that allows for fine-grained node localization in networks of inexpensive COTS nodes. In this paper, we show that the approach can also be applied to precision tracking of mobile sensor nodes. We introduce inTrack, a cooperative tracking system based on radio-interferometry that features high accuracy, long range and low-power operation. The sy...

This paper deals with the hardware implementation of base band (acquisition and tracking) modules of a GPS receiver using system generator 9.2 has been tried out. The implementation will be tested on Lyrtech (small form factor-software defined radio) platform which consists of 3 layers. The upper layer is the radio frequency (1 GHz) layer, middle layer is the ADACMasterIII layer and the last is...

This paper introduces Topic Tracking for Punjabi language. Text mining is a field that automatically extracts previously unknown and useful information from unstructured textual data. It has strong connections with natural language processing. NLP has produced technologies that teach computers natural language so that they may analyze, understand and even generate text. Topic tracking is one of...

In modern and crowded traffic life, it becomes mandatory to save the human life by reaching the hospital very sooner than possible. This paper explains about the advancement in tracking the ambulance presence amidst the traffic with the usage of GPS tracking system calculating the position of the ambulance from the traffic signal which replaces the RF transmitter receiver circuitry. This paper ...
