16. Biomass patterns in boreal-subarctic lake food webs along gradients of light and nutrients
Sammanfattning : There is large natural variation in light and nutrient conditions across lakes. In the boreal-subarctic region most lakes are small, shallow and nutrient poor. In such lakes there is often sufficient light to support primary production at the lake bottom. LÄS MER
17. Mesoscopic phenomena in the electromechanics of suspended nanowires
Sammanfattning : Over the last two decades nanotechnology has been a very active field of scientific research, both from fundamental perspectives as well as for applications in technology and consumer goods. In this thesis, theoretical work on quantum mechanical effects on charge transport in nanoelectromechanical systems is presented. LÄS MER
18. On perfect simulation and EM estimation
Sammanfattning : Perfect simulation and the EM algorithm are the main topics in this thesis. In paper I, we present coupling from the past (CFTP) algorithms that generate perfectly distributed samples from the multi-type Widom--Rowlin-son (W--R) model and some generalizations of it. LÄS MER
19. Optical interconnects and high frequency electronic packaging : SBU-materials, material characterization, LAP- & microprocessing
Sammanfattning : The main objective of this thesis is to discuss and demonstrate optical interconnect technologies. These can be used to enhance the data throughput capacity of future printed circuit boards and backplanes, i.e. exchange Copper conductors with light conductors. LÄS MER
20. Spins and Giants : Fundamental Excitations in Weakly and Strongly Coupled ABJM Theory
Sammanfattning : The discovery of integrability on both sides of the duality between planar N=4 super Yang-Mills theory and free type IIB string theory in AdS5 × S5 has lead to great progress in our understanding of the AdS/CFT correspondence. Similar integrable structures also appear in the more recent three-dimensional superconformal N=6 Chern-Simons-matter theory constructed by Aharony, Bergman, Jafferis and Maldacena (ABJM), as well as in its gravity dual, type IIA string theory on AdS4 × CP3.
