The role of the passing mechanism in traffic flows is examined. Specifically, we consider passing rates that are proportional to the difference between the velocities of the passing car and the passed car. From a Boltzmann equation approach, steady-state properties of the flow such as the flux, average cluster size, and velocity distributions are found analytically. We show that a single dimens...

With high quality editing of video shots of arbitrary duration in mind, we focus on this problem: how to construct accurate dense fields of correspondences over extended time periods using series of elementary optical flows. Highly elaborated optical flow estimation algorithms are at hand, and they were applied before for dense tracking by simple accumulation, however with unavoidable position ...

This paper presents a technique for estimating the threedimensional velocity vector field that describes the motion of each visible scene point (scene flow). The technique presented uses two consecutive image pairs from a stereo sequence. The main contribution is to decouple the position and velocity estimation steps, and to estimate dense velocities using a variational approach. We enforce the...

background: serological assay based on dense granular (gra) proteins of toxoplasma gondii (t. gondii) is actually the most popular laboratory diagnostic tool to detection of toxoplasmosis. we aimed to construct a recombinant gra7-ptz57rt plasmid vectors that it is suitable for sub-cloning and gra7 protein production. m aterials and methods: souris mice were used for maintaining of t. gondii tac...
