1. 1. Exact inference in Bayesian networks and applications in forensic statistics

   Författare :Ivar Simonsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; forensic statistics; familial relationship inference; Bayesian networks; variable elimination; exact inference; mutation models;

   Sammanfattning : Bayesian networks (BNs) are commonly used when describing and analyzing relationships between interacting variables. Approximate methods for performing calculations on BNs are widely used and well developed. LÄS MER

3. 2. Stability theory in finite variable logic

   Författare :Marko Djordjevic; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; MATEMATIK; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

   Sammanfattning : This thesis studies finite variable theories. To be more precise. complete Ln -theories, where Ln is the set of formulas in a first order language L in which at most n distinct variables occur. These need not be complete in the usual first order sense. LÄS MER

4. 3. Bayesian networks: exact inference and applications in forensic statistics

   Författare :Ivar Simonsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian networks; variable elimination algorithm; forensic statistics; relationship inference; mutation models; relationship inference;

   Sammanfattning : Exact inference on Bayesian networks has been developed through sophisticated algorithms. One of which, the variable elimination algorithm, identifies smaller components of the network, called factors, on which local operations are performed. In principle this algorithm can be used on any Bayesian network. LÄS MER

5. 4. Variable surface molecules of the plasmodium falciparum infected erythrocyte and merozoite

   Författare :Malin Haeggström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :P.falciparum; infected erythrocytes; transport; Maurer s clefts; antigenic variation; PfEMP1; RIFIN; SURFIN; merozoites; subgroups;

   Sammanfattning : As Plasmodium falciparum parasites matures within the infected erythrocyte (IE) it produces a number of various proteins, which are transported out to the cell surface where they are exposed to the host immune system. To avoid recognition and elimination by the liver and spleen these proteins can undergo antigenic variation, a phenomenon where the parasites switch from expressing one variant to' another, both belonging to the same gene-family.

7. 5. Nickel and iridium pincer complexes with saturated frameworks - synthesis and reactivity

   Författare :Klara Jonasson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCP complexes; aliphatic pincer ligands; coordination; cyclometallation; iridium; nickel; organometallic synthesis; CO2 activation; catalysis;

   Sammanfattning : As the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. LÄS MER
