Social behaviour has a key role in animal survival across species, ranging from insects to primates and humans. However, the biological mechanisms driving natural interactions between multiple animals, over long-term periods, are poorly studied and remain elusive. Rigorous and objective quantification of behavioural parameters within a group poses a major challenge as it requires simultaneous m...

Radio frequency identification (RFID) is poised for growth as businesses and governments explore applications implementing RFID. The RFID technology will continue to evolve to meet new demands for human and target location and tracking. In particular, there are increasing needs to locate and track multiple RFID-tagged items that are closely spaced. As a result, localization and tracking techniq...

Radio Frequency Identification (RFID) systems promise large scale, automated tracking solutions but also pose a threat to customer privacy. The tree-based hash protocol proposed by Molnar and Wagner presents a scalable, privacy-preserving solution. Previous analyses of this protocol concluded that an attacker who can extract secrets from a large number of tags can compromise privacy of other ta...

In MRI of the human brain, subject motion is a major cause of magnetic resonance image quality degradation. To compensate for the effects of head motion during data acquisition, an in-bore optical motion tracking system is proposed. The system comprises two MR-compatible infrared cameras that are fixed on a holder right above and in front of the head coil. The resulting close proximity of the c...

In many cases, radio-frequency catheter ablation of the pulmonary veins attached to the left atrium still involves fluoroscopic image guidance. Two-dimensional X-ray navigation may also take advantage of overlay images derived from static pre-operative 3D volumetric data to add anatomical details otherwise not visible under X-ray. Unfortunately, respiratory motion may impair the utility of stat...

We present a precise thermometry system to monitor room-temperature components of telescope for radio-astronomy such as cosmic microwave background (CMB) observation. The realizes precision 1 mKs on timescale 20 s at 300 K. achieved this high by tracking only relative fluctuation and combining thermistors with low-noise measurement device. show the required temperature monitors CMB observation ...

Radio frequency identification (RFID) technology has already been applied in a number of areas to facilitate the tracking process. However, the insufficient tracking accuracy of RFID is one of the problems that impedes its wider application. Previous studies focus on examining the accuracy of discrete points RFID, thereby leaving the tracking accuracy of the areas between the observed points un...

In this paper we describe the speaker tracking and clustering system that we implemented for the ESTER evaluation campaign. We present some experiments on normalization in speaker tracking, in particular concerning the use of t-norm for speaker tracking in broadcast news. Results show that the use of t-norm significantly improves the performance at low false alarm rates. In a second part of the...

BACKGROUND Accurate estimates of movement behavior and distances travelled by animals are difficult to obtain, especially for small-bodied insects where transmitter weights have prevented the use of radio-tracking. METHODOLOGY/PRINCIPAL FINDINGS Here, we report the first successful use of micro radio telemetry to track flight distances and space use of bumblebees. Using ground surveys and Ces...

Abstract The work on the project was focused implementation of a commercial PAN network in radio tomography system as more precise method tracking objects inside buildings that do not require presence user device. solution to be an alternative inaccurate systems using beacons and scaling RSSI indicator.
