Abstract In order to quantitatively evaluate the one-dimensional site seismic response analysis methods, this article selected 2418 ground motion records of Japan KiK-net strong-motion seismograph network and groups acceleration spectra calculated by DEEPSOIL, SHAKE2000, SOILQUAKE SOILRESPONSE, then` used dynamic time warping (DTW) algorithm calculate DTW distance between measured spectrum spec...

The present article discusses a role of psychophysical experiment as a powerful facility of psychodiagnostics and an instrument of professional selection. The experimental study shows that individual characteristics of signal detection during the changing a priori probability of the signal can be a base for the efficient forecast of success of real activity of the man-operator. Statistical sign...

A method is presented for determining the local magnitude, NIL, from records from seismoscopes and similar instruments. The technique extrapolates the maximum response of the standard Wood-Anderson seismograph, which determines ML, from the maximum response of the seismoscope. The standard deviation of the steady-state response of an oscillator subjected to white noise excitation is used to der...

Geyser and volcano monitoring suffer from temporal, geographic, instrumental biases. We present a recording bias identified through multiyear of Steamboat in Yellowstone National Park, USA. Eruptions are the tallest any geyser world they produce broadband signals at two nearby stations Park Seismograph Network. In winter, we observe lower eruption signal amplitudes these seismometers. Instead s...

Reduction of seismic velocities has been employed to study the hydration incoming plates and forearc mantle in recent years. However, few constraints have obtained Southern Mariana Trench. We use an ocean bottom seismograph (OBS) deployment conduct Rayleigh wave tomographic studies derive SV-wave velocity structure near Measured group phase as a function period are inverted determine using Baye...

Let $pounds$ be the category of locally compact abelian groups and $A,Cin pounds$. In this paper, we define component extensions of $A$ by $C$ and show that the set of all component extensions of $A$ by $C$ forms a subgroup of $Ext(C,A)$ whenever $A$ is a connected group. We establish conditions under which the component extensions split and determine LCA groups which are component projective. ...
