This dissertation describes the development of receiver function processing methods to create images of the seismic structure of the crust and upper mantle from teleseismic earthquake arrivals. These methods include receiver function estimation and prestack migration techniques which reduce deconvolution instability and produce regularized, multi-phase receiver function images. The receiver fun...

Introduction: The possibility of depression is common in the elderly. Novel technologies allow us to monitor people related to depression. Hence, a model was provided to detect depression in elderly based on artificial neural network (ANN). Methods: The present study is an applied descriptive-survey research. Forty elderly people were randomly selected from the Elderly Care Center in Gonbad Ka...

The Differential Code Biases (DCB), which are also termed hardware delay biases, are the frequency-dependent time delays of the satellite and receiver. Possible sources of these delays are antennas and cables, as well as different filters used in receivers and satellites. These instrumental delays affect both code and carrier measurements. These biases for satellites and some IGS stations tend ...

Receiver function analysis is one of the most powerful methods for modeling the subsurface structure beneath a seismograph station. Based on the assumption that similar receiver functions should be observed at stations located close to each other, we can construct a spatial distribution of a seismic velocity interface, such as the Moho discontinuity, to trace the distribution of P-to-S (Ps) con...

The estimation of channel coefficients constitutes a major function of the receiver. It is also an important step in the signal detection process at the receiver, in a wireless communication system. To describe the spacetime channel from multiple transmitters to a single receiver, many parameters are required. This means that in order to perform channel estimation and signal detection, the orde...

in this paper we introduce strongly $left[  v_{2},lambda_{2},m,pright]-$summable double vsequence spaces via orlicz function and examine someproperties of the resulting these spaces. also we give natural relationshipbetween these spaces and $s_{lambda_{2}}-$statistical convergence.

SUMMARY P-to-S and S-to-P receiver functions are widely used to constrain the seismic discontinuity structures of Earth. Typically, projected depth location conversion assuming a 1-D layered Earth structure. Receiver function finite frequency sensitivity kernels have potential increase resolution. Here we present method for rapidly calculating P- S-wave kernels, based upon shortest path Dijkstr...
