1. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. LÄS MER
2. The effects of management practices and environmental variables on the biodiversity of Nardus grasslands in the national park Hohe Tauern, Austria
Master-uppsats, SLU/Dept. of EcologySammanfattning : Introduction. A large part of the biodiversity of the Alps is linked to an interaction between the natural environment and traditional land-use practices. This study focuses on the priority habitat type of species rich Nardus grasslands (Natura 2000 Code 6230*), which is endangered, but continues to thrive in extensively managed subalpine pastures.

3. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.

4. Speckle suppression in ultrasound images of heterogeneous materials
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : Performing non-destructive testing (NDT) on materials is a helpful tool for maintenance and quality control because the materials are not destroyed or disturbed; ultrasound imaging is one type of NDT. Ultrasound imaging of heterogeneous materials contains many echoes from the material itself. LÄS MER
5. Ekologisk funktionalitet i Malmö : En jämförande undersökning av biodiversitet i Varvsparken & Strandparken
Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)Sammanfattning : Ett stort hot mot biologisk mångfald är urbaniseringen, då utbyggnad av städer leder till attplatser som tidigare utgjort viktiga habitat ersätts av hårdgjorda ytor, byggnader och mänskligaktivitet. Det finns ett nytt tankesätt inom stadsplanering, nämligen förtätning. LÄS MER
