1. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)
Master-uppsats, Uppsala universitet/GeofysikSammanfattning : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.

2. Discrete time variational mechanics of multidomain systems : Applications to coupled electronic, hydraulic, and multibody systems
Master-uppsats, Institutionen för fysikSammanfattning : Today there exist few non-smooth multi-domain simulation tools using time-discretized Lagrangian mechanics for circuits.The main goal is to show that itis possible to use a semi-implicit, parameter free non-smooth variational timestepper to simulate the circuits with time-steps proportional to the system timescales.

3. Att lösa reglertekniska problem med Modelica
Magister-uppsats, ReglerteknikSammanfattning : Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components. LÄS MER
4. Magnetic grain-size analyses of Holocene sediments in the North Atlantic and Norwegian Sea : palaeoceanographic applications
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : High-resolution magnetic hysteresis measurements were carried out on three sediment cores, one from the North Atlantic and two from the Norwegian Sea. These measurements can be used to reconstruct changes in magnetic grain-size. Physical grain-size has been interpreted as a proxy for bottom current intensity (McCave et al. LÄS MER
