The instantaneous speed ratio between roller and workpiece is not only the basis of the relative movement relationship but also the key to deriving the curve of non-rotating shafts with cross wedge rolling. In the paper, the instantaneous speed ratio was analyzed by using FEM. Then, the ...
THE consideration of an instantaneous monodirectional point source for the solution of the single-speed transfer equation is of twofold interest. On the one hand, in a number of problems for non-stationary collimated sources of small extent the model of the instantaneous monodirectional point source ...
Obstacles can be of polygonal shape and their instantaneous speed vector is unknown to robot. Robot is having detectors or range sensors to get the velocity profile of obstacles. The velocity of the obstacle is VO¯ and the Collision Cone, CCR,OB can be defined as the set of relative ...
Instantaneous speed is the magnitude of instantaneous velocity. Usually the direction of the displacement is known from context and the speed is used as shorthand for the velocity, e.g. 50 mph vs 50 mph 'east'. To be careful we should include the direction of the displacement in the ...
This fact forces to consider the response of G to the instantaneous intensity via Eq. (2): G has in this case a τ dependence and thus the pulse broadening brought about by the gain cannot be modeled by (5) (in fact it cannot be modeled properly in existing ME theories). The ...
What is the equation for acceleration?Acceleration:The object's acceleration can be described as the vector quantity representing how fast and in which direction the object is moving. The determining factor of the acceleration is the object's initial and final velocities and the time in which it...
v= wave velocityt= instantaneous timex= position of particle from originNote:(a) If the sign between t and x terms is negative, the wave propagates along the positive X-axis, and if the sign is positive, the wave moves in a negative x-axis direction....
Thus we can write the wave equation for the instantaneous density fluctuation to obtain the Lighthill equation in its final form (2.48)∂2∂t2(ρ−ρ0)−c02∇2(ρ−ρ0)=∂2∂yi∂yjTij+∂q∂t where we now introduced the fluctuation of pressure p–p0 into the stress ...
For α = 1 smoothing property is instantaneous for ∂tu and asymptotic for u ( see [5]). It is well known that when α = 0 equation (1.1) enjoys finite speed of propagation property. In the presence of the non-linear term of type f (u) ∼ u|u|q even well-posedness becomes ...
