The Kinect sensor was introduced in November 2010 by Microsoft for the Xbox 360 video game system. The sensor unit is connected to a base with a motorized pivot. It was designed to be positioned above or below a video display and to track player body and hand movements in 3D space, which allows users to interact with the Xbox 360. The device contains a RGB camera, depth sensor, IR light source, three-axis accelerometer and multi-array microphone, as well as supporting hardware that allows the unit to output sensor information to an external device. In this article we evaluate the capabilities of the Kinect sensor as a data acquisition platform for use in physics experimentation. Data obtained for a simple pendulum, a spherical pendulum, projectile motion and a bouncing basketball are presented. Overall, the Kinect is found to be both qualitatively and quantitatively useful as a motion data acquisition device in the physics lab.
The use of a strongly donating "(bis-dialkylphosphine)Ni" fragment promotes the catalytic coupling of a large range of ArCl and ArZnCl derivatives under mild conditions. Stoichiometric mechanistic investigations and DFT calculations prove that a Ni(0) /Ni(II) cycle is operative in this system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
