1. Vegetation on lava fields in the Hekla area, Iceland
Sammanfattning : .... LÄS MER
2. Volcanism at the tip of a propagating rift : the Heimaey volcanic centre, south Iceland
Sammanfattning : Primary magmas are generated by 4-6% partial melting near the garnet-spinel stability fields beneath Heimaey (i.e. 80-65 km depth). The magmas fractionate 31% olivine and clinopyroxene en-route to ponding at the base of the crust (and forming a parental Vestmannaeyjar magma). LÄS MER
3. Post-Svecokarelian geologic evolution in central Sweden, with special emphasis on burial metamorphism
Sammanfattning : Granitoids and associated volcanics, postorogenic in relation to the Svecokarelian orogeny ending at ca. 1800-1750 Ma, constitute a belt in central Sweden. LÄS MER
4. Towards Enabling Exploration of Planetary Subterranean Environments using Unmanned Aerial Vehicles
Sammanfattning : This thesis presents a novel navigation framework established to enable the exploration of planetary subterranean areas with Unmanned Aerial Vehicles (UAVs). The key contributions of this thesis work form a robot-safe rapid navigation framework that utilizes a novel bifurcating frontier-based exploration approach. LÄS MER
