โฆ Synopsis
A simple method for estimating the dynamic properties of isolators is described. The experimental set-up consists of a seismic mass with isolators installed on an electrodynamic shaker. The method enables experiments with a relative wide frequency range and with different excitation levels. In this study, random and sinusoidal excitations are used and analysis is based on the acceleration signals at input and output sides of the isolators. The measured results of helical wire rope isolators are shortly presented.

Many different non-linear identification methods have been developed so far. Most of them proceed from various experimental or numerical approaches. Inside the cost action F3 project, one common benchmark was chosen to test several identification methods in order to compare their efficiencies and th
## Abstract This paper describes the LINPACK Benchmark and some of its variations commonly used to assess the performance of computer systems. Aside from the LINPACK Benchmark suite, the TOP500 and the HPL codes are presented. The latter is frequently used to obtained results for TOP500 submissions
