1. Geological 3D Modelling ofthe File Hajdar Quarry, Slite
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Located on the island of Gotland, Sweden, the File Hajdar limestone quarry is an important locality for domestic cement production. With depositional settings generally related to shallow sea carbonate ramps, the lithologies encountered on File Hajdar range from reef-associated limestone units to more basinal deposition of marls.

2. First principles investigation of the thermal conductivity of Zr, ZrC, and ZrN
University essay from KTH/FysikAbstract : The thermal conductivity and electrical resistivity of Zr, ZrC, and ZrN were calculated using first-principles density functional theory (DFT) and the Boltzmann transport equation. The electron-phonon scattering was modeled via the self-energy relaxation time approximation (SERTA), and the phonon-phonon scattering via the analogous single-mode relaxation time approximation (SMRTA).

3. The Influence of Roughness on Electrical Properties of Single Rock Fractures
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. READ MORE

5. Developing data processing program for a new radio magnetotelluric (RMT) instrument
University essay from Uppsala universitet/GeofysikAbstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE
