Simulation of artificial earthquake records using Point Source method with applying amplification effects
Today to design large hydraulic structures like dams, application of dynamic analysis in time domain seems very interesting due to its benefits. For applying such analysis, appropriate earthquake records that are compatible to site conditions are necessary for designer. Such information is rarely recorded for a dam site during an earthquake and usually the amount of recorded data is not suffici...
متن کاملParameters estimation of point moving source with time-frequency transformation
A new parameter estimation method for a point moving harmonic source with unknown moving velocity and frequency is presented in this paper. The time-frequency representation of the source signal is taking the place of traditional time correlation estimation methods. For a harmonic source moving at constant velocity, the received signal which is amplitude and frequency modulated has no spatial c...
متن کاملPoint - source scalar turbulence
The statistics of a passive scalar randomly emitted from a point source is investigated analytically. Our attention has been focused on the two-point equal-time scalar correlation function. The latter is indeed easily related to the spectrum, a statistical indicator widely used both in experiments and in numerical simulations. The only source of inhomogeneity/anisotropy is in the injection mech...
متن کاملLocal Tsunamis and Earthquake Source Parameters
A persistent problem in estimating the severity of local tsunamis generated by earthquakes is explaining the great event-to-event variability of tsunami run-up heights relative to the magnitude of the earthquake. Undoubtedly, there is always variability in run-up that is dependent on local bathymetry. However, many earthquakes in recent years have produced unexpectedly high local run-up heights...
متن کاملOptimizing point-source parameters for scanning satellite surveys
We describe a method for deriving the position and flux of point and compact sources observed by a scanning survey mission. Results from data simulated to test our method are presented, which demonstrate that at least a 10-fold improvement is achievable over that of extracting the image parameters, position and flux, from the equivalent data in the form of pixel maps. Our method achieves this i...
