Oscillatory base manipulator (OBM) is a kind of mechanical system suffering from unexpected oscillations. The oscillations affect tremendously stability. Various control methods have been explored, but most them require measurement or prediction the This study concerned with novel OBM—the autoloader, which used in modern, autonomous main battle tanks. oscillation autoloader hard to be obtained ...

in this paper, optimum location of power system stabilizers in order to damp inter-area oscillations has been investigated by using modal series method. nonlinear effects grow in dynamical behaviors of heavily loaded stressed power systems significantly. hence linear based methods and techniques no longer present clear and exact response of the systems. in this article by defining new nonlinear...

This work presents the face-centred finite volume (FCFV) paradigm for simulation of compressible flows. The FCFV method defines unknowns at face barycentre and uses a hybridisation procedure to eliminate all degrees freedom inside cells. In addition, Riemann solvers are defined implicitly within expressions numerical fluxes. resulting methodology provides first-order accurate approximations con...

Let (un) be a sequence of real numbers and L be an additive summability method with some property. We show that if slow decrease of (un) or one-sided boundedness of the classical control modulo of the oscillatory behavior of (un) is a Tauberian condition for a general summability method L, then one-sided boundedness by a sequence with certain conditions of the general control modulo of the osci...

Abstract: The Gibbs phenomenon refers to the lack of uniform convergence which occurs in many orthogonal basis approximations to piecewise smooth functions. This lack of uniform convergence manifests itself in spurious oscillations near the points of discontinuity and a low order of convergence away from the discontinuities. Here we describe a numerical procedure for overcoming the Gibbs phenom...

Numerical methods for strongly oscillatory and singular functions are given in this paper. We present an alternative numerical solution for of oscillatory integrals of the general form Where and are smooth functions in the interval [a, b]. Also ε ω and . In order to achieve this goal and avoid singularity, the mentioned integral is solved by the modified moments using interpolating at the Cheby...
