Accuracy of Shock Response in Time History Analysis
Seismic Engineering, Volume 1, 2004A very small time step may be needed in the solution of the shock response from an impulse. In fact, this time step might be much smaller than the time step to have accurate representation of the impulse and negligible period distortion. It will be proved that the discontinuity in external force at the end of an impulse is responsible for this ...

Redundant wavelet analysis applied to GRB time histories
Fourth Huntsville gamma-ray burst symposium, 1998We apply Redundant Wavelet Transforms (RWTs) to GRB time histories in order to identify significant structures on various time scales. While the classical Discrete Wavelet Transform (DWT) also carries out a data compression and a denoising, it does not lead to a description as a set of peaks.

REMEDY FOR LOAD DISCONTINUITY IN TIME HISTORY ANALYSIS
International Journal of Structural Stability and Dynamics, 2012Discontinuity at the end of an impulse will lead to an amplitude distortion in a time history analysis. This amplitude distortion can be effectively reduced, if a very small time step is used to perform a complete step-by-step integration procedure. As a result, a lot of computational effort is involved.

A Discrete-Time Method for the Analysis of Event Histories
1992Abstract In demographic longitudinal studies, time measurements in the data are mostly reported in a rounded form: a time unit is fixed, typically a month or a year, and then the interval (of unit length) during which the event in question occurred is reported. Such rounding does cause some problems, however.

Optimum load time history for non‐linear analysis using dynamic relaxation
International Journal for Numerical Methods in Engineering, 1986AbstractA modification of the dynamic relaxation method is proposed which facilitates static analysis of non‐linear problems. Continuous loading in time is adopted instead of the ordinary step function of time. Inertia and damping forces arising during the loading process are kept at a minimum using an optimum load time history.
