Based on the parallel computing cluster platform of the ABAQUS software, a large-scale 2D finite-element refined nonlinear modeling approach was used to study seismic site effects in the Fuzhou basin, such as peak ground acceleration (PGA), spectral acceleration, duration, and acceleration transfer functions. A 1D equivalent linear wave propagation analysis was conducted also, with Proshake for...
The site response transfer functions using 1D layered velocity models based on microtremor array exploration in the Niigata area, Japan, were examined whether it would be possible to explain the estimated high-frequency site responses using observed earthquake records or not. Our results showed the site response transfer functions were relatively larger in the frequency over about 3 or 6 Hz tha...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
ABSTRACT We estimate the amplitude of nano-Hz stochastic gravitational wave background (GWB) resulting from an unresolved population inspiralling massive black hole binaries (MBHBs). To this aim, we use L-Galaxies semi-analytical model applied on top Millennium merger trees. The dynamical evolution MBHBs includes friction, stellar and gas binary hardening, (GW) feedback. At frequencies proved b...
The effect of smearing the temporal envelope on the speech-reception threshold (SRT) for sentences in noise and on phoneme identification was investigated for normal-hearing listeners. For this purpose, the speech signal was split up into a series of frequency bands (width of 1/4, 1/2, or 1 oct) and the amplitude envelope for each band was low-pass filtered at cutoff frequencies of 0, 1/2, 1, 2...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
objective: in electrochemotherapy (ect), there is an unpleasant sensation of muscle contraction when using a low frequency (1 hz). therefore, by increasing the pulse frequency above the tetanic frequency this painful sensation can be reduced. the aim of the present study is to compare the treatment efficiencies of low and high frequency ect, and estimate the effect of its repeated sessions. mat...
The three-dimensional (3-D) properties of the translational vestibulo-ocular reflexes (translational VORs) during lateral and fore-aft oscillations in complete darkness were studied in rhesus monkeys at frequencies between 0.16 and 25 Hz. In addition, constant velocity off-vertical axis rotations extended the frequency range to 0.02 Hz. During lateral motion, horizontal responses were in phase ...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
