Physlets use simple graphics to convey only the salient features of physical phenomena. Physlet-based exercises can be used as part of almost any curriculum with almost any teaching style. Physlets are created and controlled with JavaScript, meaning that with only 24 Physlets, there can be hundreds of Physlet-based exercises created.
In particle physics, tracking is the process of reconstructing the trajectory (or track) of electrically charged particles in a particle detector known as a tracker.The particles entering such a tracker leave a precise record of their passage through the device, by interaction with suitably constructed components and materials.
The UDP tracker protocol is a high-performance low-overhead BitTorrent tracker protocol. It uses the stateless User Datagram Protocol (UDP) for data transmission instead of the HTTP protocol (over TCP ) regular trackers use.
An Apple Watch showing the numbers that track a typical run. A fitbit watch showing conditions for a workout A Garmin watch tracking activity and health data. Many devices primarily intended as smartwatches also function as fitness trackers. An early example was the Apple Watch, which has offered fitness tracker functions since 2014. [15]
In computer vision, the Kanade–Lucas–Tomasi (KLT) feature tracker is an approach to feature extraction. It is proposed mainly for the purpose of dealing with the problem that traditional image registration techniques are generally costly. KLT makes use of spatial intensity information to direct the search for the position that yields the ...
A 60-foot dish mechanical tracking radar built by General Electric. Deployed at Shemya Island, Alaska, as a UHF radar and upgraded to L-Band in 1964. Used as tracker radar for Spacetrack network measurements once target detected. Principally used for intelligence purposes to track Russian missiles.
Opentracker is a free (licensed as beerware) BitTorrent peer tracker software (a special kind of HTTP or UDP server software) that is designed to be fast and to have a low consumption of system resources.
A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position (geotracking) to determine its location.
