INPUT MOTION OF AN ACTUAL RIGID EMBEDDED FOUNDATION DUE TO SPATIALLY VARIABLE SEISMIC GROUND MOTIONS
in this work, we study a unilateral contact problem with non local friction of coulombbetween a locking material and a rigid foundation. in the first step , we present the mathematicalmodel for a static process, we establish the variational formulation in the form of a variationalinequality and we prove the existence and uniqueness of the solution. in the second step, usingthe penalty method we...
Abstract The present article focuses on the analytical approach to discuss thermo–vibrational convection in a suspension of active (gyrotactic) swimmers. onset instability criterion is investigated for stationary and oscillatory modes shallow fluid layer with no–slip rigid–free walls. eigenvalue problem tackled by Galerkin scheme get desired stability diagram correlation between critical Raylei...
Waves form when the water surface is disturbed, for example, by wind or gravitational forces. During such disturbances energy and momentum are transferred to the water mass and sea-state is changed. For shallow water regions, the bottom topography affects the waves dramatically. Waves may cause evident slant of the ocean surface with large inclination angle of about 55 o . When high-speed rigid...
We describe a simple modification to a rigid endoscope so as to provide both high-quality conventional and confocal images of reasonably accessible regions of the body. This versatile system uses a structured illumination approach together with a conventional incoherent illumination source. Images taken in fluorescence are presented using this combined conventional and confocal endoscope.
