1. Value Activation with vertical annual rings - material, production, products
Sammanfattning : .... LÄS MER
2. Large-scale testing of granular material
Sammanfattning : The main problem to investigate in this study is if larger grained materials, up to 200 mm nominal size, could be used as an embankment material for high-speed railways. High-speed railways have very strict settlement requirements, allowing only very small settlements to ensure safety. LÄS MER
3. Nonlinear Dust Particle Dynamics and Collective Effects in Complex Plasmas
Sammanfattning : Theoretical studies of dusty plasmas have been performed by focusing attention principally on collective phenomena and on grain motion. This thesis consists of a collection of seven published papers that explore both the collective behavior of a complex plasma system as well as the dynamics of grains in plasmas. LÄS MER
4. Anisotropic mechanical behaviors and microstructural evolution of thin-walled additively manufactured metals
Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a concept and method of a manufacturing process that builds a three-dimensional object layer-by-layer. Opposite to the conventional subtractive manufacturing, it conquers various limitations on component design freedom and raises interest in various fields, including aerospace, automotive and medical applications.

5. Seasonal turnover in groundwater
Sammanfattning : This Licentiate Thesis presents a new approach of understanding leakage in agricultural land. Former studies concentrate on long term measurement of different pollutants in nearby watercourses and streams. The new approach is so far only numerically performed, but will soon be complemented by laboratory tests and field measurements. LÄS MER
