1. Numerical Analysis of Evolution Problems in Multiphysics
Sammanfattning : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.

2. Bi2212 intrinsic Josephson junctions, fabrication and high frequency properties
Sammanfattning : The objective for this work was to investigate the high-frequency properties of Bi2212 intrinsic Josephson junctions (IJJ’s). Particularly, the possibility to reach the THz range with a SIS mixer is theoretically promising due to the high energy gap of Bi2212. LÄS MER
3. Equilibrium and Nonequilibrium Properties of Nonionic Surfactant Membranes
Sammanfattning : An extensive investigation of the multilamellar vesicles (La*), lamellar (La), and multiply connected sponge (L3) phase formed in surfactant systems is presented in this thesis. These membrane structures were studied using surfactant systems containing poly(oxyethylene) alkyl ethers, n-CnH2n+1(OCH2CH2) mOH, commonly abbreviated as CnEm. LÄS MER
4. Coupled models related to manufacturing simulations
Sammanfattning : Manufacturing simulations is today on a level where a manufacturingchain can be simulated including various steps such as machining, welding, metal deposition and heat treatment. This opens up for the possibility to investigate different manufacturing routes without the high costsof experimental work. LÄS MER
5. Exploration of Metal Composites and Carbon Nanotubes for Thermal Interfaces
Sammanfattning : Modern microelectronics are perpetually pushing against limitations caused by inadequate heat dissipation. One of the critical bottlenecks is at the interfaces between different materials and components. LÄS MER
