Alternate modal combination methods in response spectrum analysis [PDF]

open access: yes, 1990
In piping analyses using the response spectrum method Square Root of the Sum of the Squares (SRSS) with clustering between closely spaced modes is the combination procedure most commonly used to combine between the modal response components. This procedure is simple to apply and normally yields conservative estimates of the time history results.

Relative Flux Calibration of Keck HIRES Echelle Spectra

open access: yes, 2003
We describe a new method to calibrate the relative flux levels in spectra from the HIRES echelle spectrograph on the Keck-I telescope. Standard data reduction techniques that transfer the instrument response between HIRES integrations leave errors in the

Linear response to long wavelength fluctuations using curvature simulations

open access: yes, 2015
We study the local response to long wavelength fluctuations in cosmological $N$-body simulations, focusing on the matter and halo power spectra, halo abundance and non-linear transformations of the density field.

Application of cross-oscillator, cross-floor response spectrum method of multiply supported systems, considering the correlations between three directional earthquake excitations

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Response spectrum analysis method is widely used for the seismic design of equipment and piping systems of nuclear power plant, or other industrial facilities. Some of the equipment and piping systems are multiply supported with plural floors, or several
