1. Matematiska modeller och datorberäkningar för ytdiffusion
Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaperSammanfattning : I detta arbete undersöks geometriska flöden och hur dessa kan implementeras numeriskt med fasfältsmodeller. Speciellt ligger fokus på ytdiffusion, som är ett geometriskt flöde där ändliga ytor i andra dimensionen konvergerar mot en cirkel och arean bevaras. LÄS MER
2. Design of a 2-D Lattice Flower Constellation for Earth observation applying the twin satellite concept
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Events such as forest fires or floods are a danger to our Earth’s environment and the people living in it. The sooner they can be detected, the less damage they can cause. An idea arises: use satellites to monitor the Earth and relay information to prevention and rescue organizations in a very short time, regardless of accessibility from ground. LÄS MER
3. Z2-Gauge Theory with Matter : Dispersive behaviour of a dimer in a 1+1-dimensional lattice
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : The intention with this thesis is to investigate a dimer in a spin chain. Inorder to do that, a model from Z2-gauge theory is taken as the theoretical motivation to construct a discrete lattice with Ising spin properties. A dimer is then allowed to exist indirectly in the empty space between sites. LÄS MER
4. Thermal and flow field validation of lattice Boltzmann method solver
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. LÄS MER
5. Exploratory study of additively manufactured heat exchangers for aerospace applications
Master-uppsats,Sammanfattning : Thermal management is a crucial part in the aviation industry. It is also essential that the components involved in aviation be light weight. One of the vital components of thermal management is heat exchangers. It has been observed that the optimization of the heat exchanger is approaching its saturation with traditional manufacturing.
