    Abstract: This article presents a geometrically nonlinear formulation of a two node axisymmetric shell element. The geometrically nonlinear formulation is based on the Total Lagrangian approach and the material behavior is assumed to be linearly elastic. The spherical arc-length procedure is used to obtain the pre-buckling, buckling and post-buckling deforma... Show More

    Abstract: Among the various inventory systems our method is used to find the optimal supply size. To find the optimal supply size taking in to consideration the aspects like inventory holding cost per unit, cost of shortage per unit etc., In many situation the demand taken to be a random variable. The total demand is in turn a sum of three random variables n... Show More

    Abstract: A Doppler ultrasound signal has been reconstructed using different compressed sensing algorithms. With compressed sensing it’s possible to reconstruct signals and images using a few numbers of measurements so as to overcome the limitation of sampling in a real-time Doppler ultrasound sonogram. In this work we want to compare different compressed se... Show More
