—We describe a new technique for tracking snakes that is an alternative to radio-transmitters and thread trails. We coated the bodies of three species of garter snakes (Thamnophis) in fluorescent powder, then followed and marked the trails with a UV light at night. The use of a UV light allowed us to see very detailed paths left by the snakes. This technique was effective for snakes > 10 g and ...

The significance of tracking in operations management has been overshadowed, theoretically by the concept of supply chain visibility, and practically by the attention grabbing radio frequency identification (RFID) technology. This paper describes how uses of tracking for operations management, specifically, to improve the management of project and service supply chains, were explored and develo...

Patterns of home range overlap between individuals are key parameters used in discussions of sociality in nocturnal prosimians. Despite the importance of space use variables in defining social structure in nocturnal prosimians, researchers have yet to reach a consensus concerning the most reliable techniques for measuring patterns of home range use. In this paper, we review the methods used in ...

Toronto physician Miriam Shuchman has spent the last 4 months tracking the research issues surrounding a controversial clinical trial conducted in Toronto. Much of the information appearing in this article was gathered while she was preparing a segment for the CBC Radio program Quirks and Quarks. Earlier, she had reported on similar issues in the US for the Annals of Internal Medicine.

Radio Frequency Identification (RFID) systems are now appearing in many systems and applications across enterprises and vertical markets. Spurred on by efficiencies and mandates from both private and public entities, the once obscure RFID technology of just a few years ago, is now becoming the preeminent method to meet the growing demand for tracking and identify assets and products throughout ...

The objective is to design a model based controller for a small radio-controlled helicopter in hover. To this end, a multi-input multi-output state-space model is identiied from experimental data using linear estimation. A stabilizing H1 controller with setpoint tracking is designed and is compared to a standard LQG controller.

Many research based on indoor positioning and tracking systems have been developed due to growing interest in location-aware services. Nevertheless, satisfying solutions have not been found with the considerations of both accuracy and system complexity. In fact, an indoor localization system highly accurate, low energy, widely available, and easily deployed has not yet been developed. Hence, th...

Radio-frequency identification (RFID) technology is making inroads in healthcare. Such kind of up gradation must be provided to health care industry. It reflects better results in; improvement of patient assistance, medication flaws will be omitted, patient identification becomes easier, and to locate and track capital instruments in the hospital. Meanwhile RFID technology seems effective; in c...

In this paper, we propose a low cost, robust vision based system for monitoring patient movements during stereotactic radiotherapy: the Monocular Visual Patient Movement Monitoring (MVPM) System. The system consists of a light weight mouth bite with dual fiducial system used for position tracking. One set of fiducials consist of easy-to-detect checkerboard whose 3D position can be tracked using...

Video tracking is a powerful new tool for studying natural undisturbed behaviour in a wide range of birds, mammals and reptiles. Using integrated animal-borne video tags, video footage and positional data are recorded simultaneously from wild free-ranging animals. At the analysis stage, video scenes are linked to radio fixes, yielding an animal's eye view of resource use and social interactions...
