The paper treats the semi active isolation of a single equipment, acceleration sensitive, by means of a variable elastic control device. A numerical study on a single degree of freedom (SDOF) structural model equipped with a continuously variable elastic device subjected to harmonic input is presented. The utilized control algorithm is derived by the Lyapunov method and specialized in order to ...

We have developed a dynamic model of accommodation that combines independent phasic-velocity and tonic-position neural signals to control position, velocity and acceleration properties of accommodative step responses. Phasic and tonic signals were obtained from neural integration of a fixed-height acceleration-pulse and variable-height velocity-step respectively to control independent accelerat...

The paper presents the NetCOPE experimental platform for evaluation of 100Gb/s networks. The platform consists of acceleration boards with FPGAs, FPGA firmware and control software. While the NetCOPE for 10Gb/s networks is a mature platform, multiplying the throughput ten times brings major challenges in the platform design.

A process employing a computer controlled crane system for controlling the motion of a movable trolley from which a load is suspended at a variable hoist length therefrom to meet a selected arbitrary horizontal velocity reference while preventing sway of the load involves the steps of first, determining a lateral acceleration to reduce by a factor of one-half the sway energy contributed by (1) ...
