the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...
We propose a system that reduces laser display speckles by vibrating the light pipe. A small displacement of the light pipe appears to allow the total reflection of the laser, thereby resulting in a homogenized speckle field that changes with time. In this case, the speckle interference generated by the pattern projected by the laser through the light pipe destroys the spatial homogenization of...
Comprehensive beam tracing method is a simulation method that calculates refraction as well as reflection of sound. Due to the non-linear nature of Snell’s law, refraction (in contrast to reflection) is not a linear transformation. Because of this triangular beams used in comprehensive beam tracing simulation lose focus after refraction. In this paper the problem of non-linearity of refraction ...
