21. Population viability analysis for plants : practical recommendations and applications
Sammanfattning : Population viability analysis (PVA) is commonly used in conservation biology to predict population viability in terms of population growth rate and risk of extinction. However, large data requirements limit the use of PVA for many rare and threatened species. LÄS MER
22. Functional Fibers for Biomedical and Thermal Management Applications
Sammanfattning : This thesis explores the integration of electrospun polymeric structures in two fields; fibrous scaffolds as cell culture substrates for biomedical applications and fiber carrier networks in metal matrix polymer composites as thermal interface materials in microsystems. Electrospinning has been found to carry great potential for a range of future biomedical engineering applications. LÄS MER
23. Numerical Renormalization, Doped Antiferromagnets, and Statistics - Topics in Low Dimensional Physics
Sammanfattning : The first part of the thesis deals with so called numerical renormalization group methods, and in particular the density-matrix renormalization group (DMRG). This method performs extremely well for large one-dimensional quantum systems like spin-chains and Hubbard models. LÄS MER
24. Silicon nanowire based devices for More than Moore Applications
Sammanfattning : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. LÄS MER
25. A Theoretical Study of Magnetism in Nanostructured Materials
Sammanfattning : A first-principles linear scaling real-space method for investigating non-collinear magnetic behaviour of nanostructured materials has been developed. With this method, the magnetic structures of small supported transition metal clusters have been examined. LÄS MER
