1. 1. Mapping incomplete relational data : networks in ecology & evolution

   Författare :Daniel Edler; Martin Rosvall; Alexandre Antonelli; Renaud Lambiotte; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network science; information theory; map equation; community detection; biogeography; evolution;

   Sammanfattning : We live in an interconnected world full of complex systems that cannot be understood simply by analyzing their components. From how genes regulate biological functions to the distribution of life on Earth, we need methods that can analyze systems as a whole. LÄS MER

3. 2. Optimal stopping, incomplete information, and stochastic games

   Författare :Yuqiong Wang; Erik Ekström; Sören Christensen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimal stopping; sequential analysis; incomplete information; asymmetric information; stochastic filtering; Dynkin games; tug-of-war games; Mathematics; Matematik;

   Sammanfattning : This thesis contains six papers on the topics of optimal stopping and stochastic games. Paper I extends the classical Bayesian sequential testing and detection problems for a Brownian motion to higher dimensions. We demonstrate unilateral concavity of the cost function and present its structural properties through various examples. LÄS MER

4. 3. Essays on the Economics of Networks Under Incomplete Information

   Författare :Theodoros Rapanos; Yves Zenou; Francis Bloch; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social networks; social learning; social influence; incomplete information; Bayesian game; Economics; nationalekonomi;

   Sammanfattning : Social networks constitute a major channel for the diffusion of information and the formation of attitudes in a society. Introducing a dynamic model of social learning, the first part of this thesis studies the emergence of socially influential individuals and groups, and identifies the characteristics that make them influential.

5. 4. Selfish Dynamic Spectrum Access in Multichannel Wireless Networks : Complete and incomplete information analysis

   Författare :Ali Özyagci; Jens Zander; Alexandre Proutiere; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Game theory; Multichannel random access; Bayesian game; Nash equilibrium Heterogeneous channels; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The increasing popularity and widespread deployment of wireless data systems fuel the increasing demand for more spectrum. On the other hand, various studies measuring spectrum utilization show that there is a huge variation in spectrum utilization at different times and locations. LÄS MER

7. 5. On the Asymptotics of Increasing Dimension Models : Methods for Complete or Incomplete Data

   Författare :Peter Karlsson; Thomas Holgersson; Rolf Larsson; Jönköping University; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Statistik;

   Sammanfattning : In some multivariate contexts there is a close relation between the number of parameters (p) and the number of observations (n). In a situation where p grows with n it frequently happens that the statistic does not converge to its true parameter. LÄS MER
