In this paper, block-matching with Gaussian Filter adaptive technique is proposed to estimate the motion velocity displacement point in the ultrasound image. We apply the Hexagon-Diamond Displacement Point (HDDP) technique to estimate the motion displacement. The motion displacement is based on the hexagon and diamond displacement pattern search points. The displacement pattern search point is ...

This paper introduces a novel methodology for the optimum design of linear tuned mass dampers (TMDs) to improve seismic safety structures through Whale Optimization Algorithm (WOA). The algorithm is aimed reduce maximum horizontal peak displacement structure, and root mean square (RMS) response displacements as well. Furthermore, four additional objective functions, derived from multiple weight...

An image pattern tracking algorithm is described in this paper for time-resolved measurements of miniand micro-scale movements of complex objects. This algorithm works with a high-speed digital imaging system, which records thousands of successive image frames in a short time period. The image pattern of the observed object is tracked among successively recorded image frames with a correlation-...

b = vortex spacing l = lateral displacement N = Brunt–Väisälä frequency q = root-mean-square turbulence velocity t = time u = axial velocity v = lateral velocity, vertical displacement V = aircraft ground speed w = descent speed, vertical wind velocity x = axial coordinate y = spanwise coordinate z = vertical coordinate = circulation = eddy dissipation rate = potential temperature = standard de...

the aim of this study was to evaluate the effects of dilution rate and holding time on various motility parameters using computer-assisted sperm analysis (casa). the semen samples were collected from three ghezel rams. samples were diluted in seminal plasma (sp), phosphate-buffered saline (pbs) containing 1% bovine serum albumin (bsa) and bioexcell. the motility parameters that computed and rec...

The complexity of networks has outpaced our tools to debug them; today, administrators use manual tools to diagnose problems. In this paper, we show how packet histories—the full stories of every packet’s journey through the network—can simplify network diagnosis. To demonstrate the usefulness of packet histories and the practical feasibility of constructing them, we built NetSight, an extensib...

In this paper, transverse and longitudinal vibration of nonlinear plate under exciting of orbiting mass is considered based on first-order shear deformation theory. The nonlinear governing equation of motion are discretized by the finite element method in combination with Newmark’s time integration scheme under von Karman strain-displacement assumptions. For validation of method and formulation...
