Anxiety and depression are very common in population and occur in a wide range of clinical states and is very common in epileptic patients. Many recent epidemiological studies have found a high prevalence of depression and anxiety in epileptic patients. These studies found that epileptic patients suffered from depression and anxiety than those without epilepsy. The prevalence of depression or a...

Data coverage, expressed as path density of Rayleigh wave group velocities, is shown in Figure 1. Coverage is best at intermediate periods, and reduces particularly at very long periods. It is also considerably lower for Love waves than for Rayleigh waves, especially at periods above about 100 sec. Resolution estimates are shown in Figure 2. Average resolution across the Paci c is about 600 km ...

There are several reports about thermal anomalies associated with the impending earthquakes (EQs); among which underlying mechanism is linked main shock long, intermediate and short-term precursors. In this paper, we analyzed from Moderate Resolution Imaging Spectroradiometer (MODIS) based Land Surface Temperature (LST) of three different magnitudes shallow depth EQs in Pakistan. Our focus to i...

Abstract Noise attenuation is a major seismic data processing concern. In seismic data, noise can appear as random, coherent and/or impulsive. Recently, many different techniques, ranging from relatively simple processes to extremely complex ones, have been used for noise attenuation. Image filtering techniques are relatively new methods in seismic exploration. We introduced the anisotropic non...

With the growing demand of high-resolution subsurface characterization from 3D seismic surveying, the size of 3D seismic data has been dramatically increasing, and correspondingly, the process of interpreting seismic data is becoming more time consuming and labor intensive. Recently, there has been great interest in various supervised machine learning techniques that can help reduce the time an...

High-resolution 3-D P and S wave crustal velocity and Poisson’s ratio models of the 1992 Landers earthquake (Mw 7.3) area are determined iteratively by a wave-equationbased travel-time seismic tomography (WETST) technique. The details of data selection, synthetic arrival-time determination, and trade-off analysis of damping and smoothing parameters are presented to show the performance of this ...

Temporal reasoning is complex. Typically, the proof methods used for temporal logics are both slow and, due to the quantity of information required, consume a large amount of space. The introduction of parallelism provides the potential for significant speedups together with the increased memory size required to handle larger proofs. Thus, we see the effective utilisation of parallelism as bein...

Earthquakes arrive without previous warning and can destroy a whole city in a few seconds, causing numerous deaths and economical losses. Nowadays, a great effort is being made to develop techniques that forecast these unpredictable natural disasters in order to take precautionary measures. In this paper, clustering techniques are used to obtain patterns which model the behavior of seismic temp...
