ABSTRACT
Four simple, low cost aerodynamic drag reduction devices have been developed for application to
the trailer of a tractor-trailer truck. Two vortex flow devices have undergone extensive
operational fleet testing where they have amassed over 85,000 miles of use. These two vortex
flow technologies have shown a combined fuel savings of 8% at an average speed of 47.5 mph.
This improvement in fuel economy correlates to an equivalent drag reduction of approximately
20% with a corresponding drag coefficient of 0.45. Observations ....etc

ABSTRACT
This paper presents results of numeric modeling of three-dimensional flow around the configuration of the piloted orbital spaceship “the winged aerospace vehicle proposed by the central Hydrodynamic Institute.The flight vehicle with nondeflected control devices was examined.The effect of the deflection of the balancing flap on the flow field and the aerodynamic performance of the vehicle is studied here.The efficiency of the flap with its deflection is obtained.Computations were perfomed using the applied p ....etc

ABSTRACT
A novel approach for estimating articulated body posture and motion from monocular video sequences is pro-posed. Human pose is defined as the instantaneous two dimensional configuration (i.e., the projection onto the image plane) of a single articulated body in terms of the position of a predetermined set of joints. First, statistical segmentation of the human bodies from the background is performed and low-level visual features are found given the segmented body shape. The goal is to be able to map these, g ....etc

Numerical Simulation for Aerodynamic Characteristics of Low Altitude and Subsonic Flight Vehicle
Abstract—In order to analyze the drag characteristics of the vehicle having different war head and empennage, the computational fluid dynamics numerical simulation was used. The method was based on fully hexahedral mesh and three-dimensional Navier-Stokes equations and Spalart-Allmaras turbulence model. Through numerical simulation the flow field structures and computational aerodynamic characteristics were obtained. T ....etc
