A method and a traffic prediction and control system (TPCS) for predicting and controlling vehicle traffic flow through a traffic intersection dynamically with proximal traffic intersections are provided. The TPCS dynamically receives sensor data from sensors at a local traffic intersection, determines traffic flow parameters, and determines a traffic flow flux using the traffic flow parameters. The TPCS dynamically receives analytical parameters from sensors at proximal traffic intersections and determines a minimum safe driving distance between leading and trailing vehicles, a traffic free flow density, a synchronized traffic flow density, and a traffic jam density to predict transitions of the vehicle traffic flow across traffic flow phases through the local traffic intersection. The TPCS controls the vehicle traffic flow by dynamically adjusting duration of traffic signals of the local traffic intersection and transmitting traffic signal time adjustment instructions to the proximal traffic intersections to maintain an optimized traffic flow flux.

Traffic prediction and control system for vehicle traffic flows at traffic intersections

A method for calibrating an apparatus for ellipsometric measurements performed on an arbitrarily large or continuously moving sample, using a visible sample reference frame, and one or more laser sources in order to calibrate the ellipsometer for variations in the distance between the ellipsometer apparatus and the sample of interest. Included are techniques for projecting a first laser beam spot from an incident laser source onto a sample, then analyzing the position of the first laser beam spot relative to the center of the sample reference frame using human-aided measurements and confirmations and/or computer vision techniques. Then adjusting pivot points and/or apparatus-to-sample distance to achieve a first beam spot being located about the center of the sample reference frame, and concurrently intersecting the plane of the sample. Other techniques include changing the incidence and reflectance angle using a semi-circular track arc design with a stepping motor activating each goniometer arm.

A thin-film magnetic recording disc for use with a read/write head in a disc drive is disclosed. To reduce the static and dynamic frictional coefficients of the disc surface, the disc is coated with a lubricant layer composed of a mixture of a polyphenoxycyclotriphosphazene lubricant and a perfluoropolyether oil. Also disclosed is a lubricant composition containing these two components, as well as a method for improving the lubricating properties of a perfluoropolyether oil.
