Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Well-being; Latent semantic analysis; Statistical semantics; Satisfaction with life; Harmony in life; Välbefinnande; Harmoni i livet; Tillfredsställelse med livet; Statistisk semantik; Latent semantisk analys;
Abstract :
How to define and measure individuals’ well-being is important, as this has an impact on both research and society at large. This thesis concerns how to define and measure the self-reported well-being of individuals, which involves both theorizing as well as developing and applying empirical and statistical methods in order to gain a better understanding of well-being.

Author : Erik Sandelin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein folding; hydrophobicity; Monte Carlo; sequence analysis; sequence assembly; shotgun sequencing; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; Fysicumarkivet A:2000:Sandelin; statistisk fysik; relativitet; protein design; klassisk mekanik; kvantmekanik;
Abstract :
The protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. READ MORE

Author : Henrik Jönsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; annealing; variational; mean-field; phylogeny; constraint satisfaction; combinatorial optimization; maximum likelihood; Physics; Fysik; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2001:Jönsson; Matematisk och allmän teoretisk fysik; thermodynamics;
Abstract :
Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is introduced, and an algorithm similar to the mean-field annealing algorithm is proposed. READ MORE

Abstract :
There are many examples of complex networks in science. It can be genetic regulation in living cells, computers on the Internet, or social and economic networks. In this context, Boolean networks provide simplistic models that are relatively easy to handle using computer simulations and mathematical methods. READ MORE
