3. 2. Learning from Interactions : Forward and Inverse Decision-Making for Autonomous Dynamical Systems

   Författare :Inês de Miranda de Matos Lourenço; Bo Wahlberg; Sandra Hirche; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intelligent systems; autonomous decision-making; Reinforcement Learning; Markov models; Human-Robot Interaction; Biologically-inspired systems; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Decision-making is the mechanism of using available information to generate solutions to given problems by forming preferences, beliefs, and selecting courses of action amongst several alternatives. In this thesis, we study the mechanisms that generate behavior (the forward problem) and how their characteristics can explain observed behavior (the inverse problem). LÄS MER

4. 3. On protein structure, function and modularity from an evolutionary perspective

   Sammanfattning : We are compounded entities, given life by a complex molecular machinery. When studying these molecules we have to make sense of a diverse set of dynamical nanostructures with wast and intricate patterns of interactions. LÄS MER

5. 4. Meson Properties in Partially Quenched Effective Field Theory

   Författare :Niclas Danielsson; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Fysik; Chiral Perturbation Theory; masses; decay constants; Physics; electromagnetic interactions; Strong interactions; pseudoscalar mesons; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

   Sammanfattning : Mass corrections and decay constants for light mesons have been calculated in Partially Quenched Chiral Perturbation Theory. The calculations of the charged meson masses have been performed to third order, first for degenerate quark masses, and then, in a second project, for the general case. LÄS MER

7. 5. Supersymmetric Gauge Theories and Matrix Models

   Författare :Rainer Heise; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; Effective field theory; Matrix model; Supersymmetric gauge theories;

   Sammanfattning : We discuss recent developments in supersymmetric field theory due to the conjecture of Dijkgraaf and Vafa relating the effective superpotential of such theories to the computation of an associated matrix model. We give a short survey of N=1 supersymmetric gauge theories and state the conjecture. LÄS MER
