This paper describes a tablet-based application to be used by novice geologists for taking geological measurements during fieldwork. The application was implemented on an iPad2. Both our app and the FieldMove Clino iOS app (from Midland Valley, a well-known geophysics software company) were compared with ground truth measurements taken using a Silva compass clinometer. The results show that the...

We introduce a new transform of offset-domain Common Image Gathers (CIGs) obtained by wavefield-continuation migration methods. This transformation can be applied to either horizontal-offset CIGs or vertical-offset CIGs. It overcomes the limitations that both kinds of CIGs suffer in the presence of a wide range of reflectors’ dips. The result of our transformation is an image cube that is equiv...

Normal mode solutions for • spherical earth model are superposed to obtain realistic synthetic surface waves for various force systems. The calculation of excitation functions is greatly facilitated by the variational technique. The effects of attenuation anal instrument response are included in the synthesis. The synthesized seismograms are compared with the actual seismograms for wave form, a...

Kinematic data from two segments of the Coast Range fault are used to test the hypothesis that the Franciscan subduction complex was exhumed by extensional faulting. The data reveal a consistent geometry for the principal directions of brittle strain. The maximum extension direction has an east-west orientation and lies subperpendicular to the present attitude of the Coast Range fault, which di...

This paper presents a comparative analysis for stabilization and control of highly non-linear, complex and multi-variable Double Inverted Pendulum on cart. A Matlab-Simulink model of DIP has been built using governing mathematical equations. The objective is to control both the pendulums at vertical position while cart is free to move in horizontal direction. The control of DIP was achieved usi...

the scope of this research is to investigate the effect of geometrical and physical input parameters in crustal viscoelastic deformation models. to do this analysis viscoelastic model of wang et al., 2006 is used. the increasing quality of data on time-dependent deformation of the earth's surface can be used to extract more details on the spatial and temporal development of earthquake-rela...

Abstract Strike-slip faults can be nonplanar in both their strike and dip dimensions. While a large body of work has investigated the effects changes on earthquake rupture arrest, no previous studies have role along-strike variations strike-slip ruptures. Here, I use three-dimensional finite-element method to conduct dynamic simulations ruptures with linear surface traces along strike. experime...

Supramolecular organic ferroelectrics have unique properties related to plasticity and freedom of design but the extensive post-deposition treatments that are typically required achieve saturation polarization limit their applicability. A possible solution is pre-align molecules. Here, effect dip-coating on pre-alignment prototypical supramolecular ferroelectric trialkylbenzene-1,3,5-tricarboxa...

To optimize the prediction of structural geological conditions in underground as data collected at surface, due to usual great uncertainties involved, we discuss new perspectives for construction models, bearing mind common doubts involved and their implications safety infrastructure works, mining, etc. This paper presents a statistical simulation applied measures (dip-dip direction) obtained f...
