Survey on Parameter Estimation Within System Identification Using a Priori Knowledge of System Analysis is based on construction drawings and technical data? its result is the predicted dynamic behaviour, which is erroneous because of simplifying assumptions. The prediction errors in general are unknown. If comparable experience is not available, and if a proof of the prediction is needed, tests h

Modal and Damage Analysis of Elastic Structures — Frequency Separation by Non-Linear Filterr high damping ratios of the system. To overcome such difficulties, we apply a non-linear modal filter by cutting off a measured signal of the response according to the momentary amplitude configuration that all measured amplitudes have the same sign if the lowest natural frequency of the system has

System Identification of Structural Dynamic Parameters From Modal Datause can be made of the data and parameters of the model to arrive at a better correlation. The corresponding objective function is minimized in an iterative manner by means of a modified Newton-Raphson scheme requiring first order derivatives of the measured quantities with respect to the parameters

Pressure Field Data Acquisition on a Physical Well Model Using a Minicomputeration Hydraulic Laboratory in Denver, Colorado. Head losses due to the effects of size, orientation, and configuration of the openings in different types of well screens can be lessened through various well development techniques. This reduction of head loss is beneficial because, when the head loss

Computer-Based Measurements Of Incipient Wave Breaking bottom-mounted, half cylinder. Steps taken at NRL to minimize extraneous waves and to develop systems and methods for acquiring and correctly interpreting the data are described along with representative test results. In addition to establishing corrective procedures the approach has permitted furt

Aquisition and Display of Data From Large Arrays of Sensors. The system produces up to 8 Chapaullel analog signals and channel address information. It is presently used in connection with a PDP 11/34 computer with 4 digital input channels and an A/D converter for 32 analog signals. The maximum scanning rate is 12800 channels per second..A method is introduc
