The dissipation rate of turbulent kinetic energy () and shear rate (γ) are the key process parameters for mixing in surface aerators. At constant dynamic variables (rotational speed), both  and γ are greatly affected by the geometric parameters (impeller diameter, cross-sectional area of the tank, liquid height, rotor blade length and immersion height). By doing numerical computation by VISIM...

Image-Based Localization (IBL) is the problem of estimating the 3D pose of a camera with respect to a 3D representation of the scene. IBL is quite challenging in largescale environments spanning a wide variety of viewpoints, illumination, and areas where matching a query image against hundreds of thousands of 3D points becomes prone to a large number of outliers and ambiguous situations. The cu...

to produce embryogenic callus and somatic embryos, tendril explants were collected and cultured in ms medium supplemented with various concentrations of hormones. after one month most of explants produced callus. the highest percent of embryogenic callus obtained in ms medium supplemented with 4.5 µm bap and 1µm 2,4-d. production of somatic embryos was depended on genotype and medium. yaghouti ...
