SIMULATING PASSIVE SUSPENSION ON AN UNEVEN TRACK SURFACE

Detection of Uneven Flatness on Liquid Surface

Abstract: This research is aimed at improving accuracy of stereolithography (Rapid prototyping) system. The objective of this paper is to detect the flatness of freeform liquid surface. The principle of measurement is performed by obtaining grating image of total reflection from freeform liquid surface. The detection is performed by two steps, coarse detection and fine one. Coarse detection is ...

Scattering of surface waves over an uneven sea-bed

This work is concerned with the scattering of a train of progressive waves by a small undulation of the bottom of a laterally unbounded sea, using two-dimensional linear water wave theory. Assuming irrotational motion, a simplified perturbation analysis is employed to obtain the first-order corrections to the velocity potential by using the Green’s integral theorem in a suitable manner, and the...

An Automated Approach to Passive Sonar Track Segment Association

The primary objective of passive surveillance is to covertly develop situational awareness. In the underwater environment, passive sonar is commonly used to detect and track targets by their own acoustic emissions. Although significant advances have been made in sensor technology and front-end signal processing, much of the work of identifying targets from a series of intensity peaks in time an...

Optimal integrated passive/active design of the suspension system using iteration on the Lyapunov equations

In this paper, an iterative technique is proposed to solve linear integrated active/passive design problems. The optimality of active and passive parts leads to the nonlinear algebraic Riccati equation due to the active parameters and some associated additional Lyapunov equations due to the passive parameters. Rather than the solution of the nonlinear algebraic Riccati equation, it is proposed ...
