Abstract:
This study work deals with the determination of the gravimetric geoid model for Kazakhstan by using the KTH-method. A number of data sets were collected for this work, such as the gravity anomalies, high-resolution Digital Elevation Model (DEM), Global Geopotential Models (GGMs) and GPS/Levelling data. These data has been optimally combined through the KTH approach, developed at the Royal Institute of Technology (KTH) in Stockholm. According to this stochastic method, Stokes’ formula is being used with the original surface gravity anomaly, which combine with a GGM yields approximate geoid heig

The main objective of this study is to compute a new gravimetric geoid model of Sudan using the KTH method based on modification of Stokes’ formula for geoid determination. The modified Stokes’ formula combines regional terrestrial gravity with long-wavelength gravity information provided by the global gravitational model (GGM). The collected datasets for this study contained the terrestrial gravity measurements, digital elevation model (DEM), GPS/levelling data and four global gravitational Models (GGMs), (EGM96, EIGEN-GRACE02S, EIGEN-GL04C and GGM03S).

Metal cutting subjects the material being cut to strains greater than 100% at high strain rates between 103/s and 106/s and may be a good test for mechanical properties in this strain rate regime. This thesis presents an experimental study of the velocity field in the primary shear zone (PSZ) while cutting OFHC copper under six different cutting conditions. A new type of ultra high speed camera is used to acquire sequences of high resolution stereoscopic microphotographs of the PSZ at frame rates from 50 kHz to 1 MHz. The velocity field is obtained by 3D stereoscopic correlation of the images.

Abstract:
Subduction zones represent a tectonic environment where the Earth's crust is subducted into the mantle, but several components are returned to the surface via arc magmatism. These include Cu and S, which form Porphyry Copper Deposits (PCD). It has been suggested these 'hot spots' of Cu represent local oxygen fugacity (fO2) anomalies resulting from strongly oxidized conditions in the magma at some stage on the journey from slab to near-surface. One obstacle to our understanding of this journey is the difficulty in controlling fO2 in high-pressure experiments representing the mid- to lower-crust
