1. Reconstruction of Fire Spread with a Markov Random Field Mixture Model
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

2. Optimal Auxiliary Variable Assisted Two-Phase Sampling Designs.
Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaperSammanfattning : Two-phase sampling is a procedure in which sampling and data collection is conducted in two phases, aiming at achieving increased precision in estimation at reduced cost. The rst phase typically involves sampling a large number of elements and collecting data on variables that are easy to measure. LÄS MER
3. Detecting contacts in protein folds by solving the inverse Potts problem - a pseudolikelihood approach
Magister-uppsats, KTH/Matematisk statistikSammanfattning : Abstract Spatially proximate amino acid positions in a protein tend to co-evolve, so a protein's 3D-structure leaves an echo of correlations in the evolutionary record. Reverse engineering 3D-structures from such correlations is an open problem in structural biology, pursued with increasing vigor as new protein sequences continue to fill the data banks. LÄS MER
