The effects of hypo-central distances and magnitude on the acceleration response spectra in this study are based 24 sites Gansu province China, all spread over loess regions. normalized with 5% damping were determined for 106 strong ground motions contained horizontal vertical components, recorded at these ranging from 3.7 to 7.0. It is shown that shape spectrum affected by not only but also di...

The deposition of x-ray energy resulting from the microexplosion i.o an inertial confinement fusion reactor and the subsequent thermal response of candidate wall coating and structural materials is examined. Evaporation losses and resulting melt layer thicknesses for these materials exposed to a variety of different x-ray energies and spectra are calculated. Softer x-ray energy spectra absorbed...

Harashima and Miyakawa [I] and Tomlinson [2] have described a generalized partial response technique which achieves the performance of the decision-feedback equalizer without the error propagation problem. We show here that when the equalized and baud-rate sampled channel assumes the special rational z transform M g;zi i-0 F ( 2 ) =

A cost effective method employing polysulphone, nalidixic acid, 8-methoxypsoralen and phenothiazine as UV dosimeters is presented for evaluating the UV spectrum. The exposure measured by each dosimeter is a function of the source spectrum and the spectral response of the material. Each material has a different spectral response and records a different dose for the same exposure. A least squares...

This paper presents the physical relationships that exist between the response spectra and the Fourier Transform of strong-motion accelerograms through the extreme value statistics of oscillator response. Under the assumption of a stationary response, it has been shown that the spectrum value depends only on two parameters: arms, the root-mean-square-value of the response, and, ~, a parameter w...

The visible absorption spectra of Radiachromic FWT-60 radiochromic film have been investigated to analyse the dosimetry characteristics of the film. The film is radiation sensitive to high absorbed doses. The visible absorption spectra of this film when exposed to photon radiation show a peak at 605 nm which is stable over the dose range of 0 Gy to 20 kGy. The radiation sensitive absorption spe...

We present the implementation of the time-dependent density-functional theory both in linear-response and in time-propagation formalisms using the projector augmented-wave method in real-space grids. The two technically very different methods are compared in the linear-response regime where we found perfect agreement in the calculated photoabsorption spectra. We discuss the strengths and weakne...

In stress response studies, metabolomics tries to individuate spectral areas or metabolites whose response to a specific stress is particularly significant. This evaluation is normally carried out with a series of tedious and time consuming comparisons of spectral areas obtained from cells subject to different stress intensities. MMS is a package written in “R” language able to individuate whic...

A simple mathematical model was used to investigate the spectral properties of the tubuloglomerular feedback (TGF) system. A perturbation, consisting of small-amplitude broad-band forcing, was applied to simulated thick ascending limb (TAL) flow, and the resulting spectral response of the TGF pathway was assessed by computing a power spectrum from resulting TGF-regulated TAL flow. Power spectra...
