Reports the enhancement of the service's intelligence, surveillance and reconnaissance capabilities of the United States Air Force. Improvement of the speed and accuracy for information gathering of the military actions in Afghanistan; Innovations on the strategy employed in unmanned aerial vehicles and ...

The magneto-mechanical testing can be both static and dynamic, which can be decided depending on the nature of the force/deformation to be experienced by the MSMs in the targeted applications. A force versus displacement can be used to characterize the mechanical properties of MSMs where the stru...
A liquid filament, free in the air, retracts by the action of surface tension. This is a classical problem that has been widely studied in the literature through theoretical, numerical and experimental methods2,3,4,5,6,7,8,9,10. However, the first significant studies on this topic were ...
In this research, an experimental study was conducted to high light the impact of the exterior shape of a cylindrical body on the forced and free convection heat transfer coefficients when the body is hold in the entrance of an air duct. The impact of changing the body location within the ...
In fact, most of sand particles in natural environment are nonspherical and usually rotating while they saltate in the air, and the complicated turbulent gas‐solid flow caused by irregular shape and rotation of particles cannot be predicted. In this paper, the microcosmic midair movements of ...
the change in shape—and particularly the fissure displacement—with age that we observe in this cohort reflects lung tissue micro-structural and elasticity changes, and their force balance with the chest wall. For example, the loss of elastic recoil with age leads to airway closure and increase...
The results of front tension stress, back tension stress, strip's exit gauge, the force between rolls and rolling force distribution calculated by model coupling method coincide very well with results coupling method. However the calculation course of model coupling method is more steady than ...
Otherwise, StylusInAirMove is raised instead. (Inherited from UIElement) StylusOutOfRange Occurs when the stylus is too far from the digitizer to be detected, while over this element. (Inherited from UIElement) StylusSystemGesture Occurs when a user performs one of several stylus gestures...
