  2. 1. Analysis of the Age of Information in Status Update Systems

    Author : Antzela Kosta; Vangelis Angelakis; Nikolaos Pappas; Dán György; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Rapid advances in wireless technology have taken us towards a pervasively connected world in which a vast array of wireless devices, from mobile phones to environmental sensors, seamlessly communicate with each other. In some of these systems the freshness of the transmitted information is of high importance. READ MORE

  4. 2. Modeling of Protein Folding and Genetic Networks

    Author : Fredrik Sjunnesson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; two-state folding; Protein folding; all-atom model; Mathematical and general theoretical physics; Kauffman model.; local update; Monte Carlo; classical mechanics; quantum mechanics; relativity; statistical physics; gravitation; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Sjunnesson;

    Abstract : Models for potein folding are developed and applied to peptides and small proteins with both α-helix and β-sheet structure. The energy functions, in which effective hydrophobicity forces and hydrogen bonds are taken to be the two central terms, are sequence-based and deliberately kept simple. READ MORE

  5. 3. Numerical Algorithms for Optimization Problems in Genetical Analysis

    Author : Kateryna Mishchenko; Sverker Holmgren; Dmitrii Silvestrov; Lars Rönnegård; Ann-Charlotte Berglund Sonnhammer; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantitative Trait Loci QTL ; restricted maximum likelihood REML ; variance components; average information AI matrix; Local optimization; Quasi-Newton method; Active Set method; Hessian approximation; BFGS update; Applied mathematics; Tillämpad matematik; Matematik tillämpad matematik;

    Abstract : The focus of this thesis is on numerical algorithms for efficient solution of QTL analysis problem in genetics.Firstly, we consider QTL mapping problems where a standard least-squares model is used for computing the model fit. READ MORE

  6. 4. Local Social Exposure and Inter-Neighborhood Mobility

    Author : Alex Giménez de La Prada; Peter Hedström; Eduardo Tapia; Petri Ylikoski; Gianluca Manzo; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ethnic segregation; residential mobility; social interdependency;

    Abstract : Studies on ethnic residential segregation analyze how the inter-neighborhood mobility of individuals shapes their spatial distribution across cities. This literature has shown that the residential choices of households partly depend on the ethnic composition of their neighborhoods: higher in-group shares promote the presence of more in-group members, and vice versa.

  7. 5. Evaluation of design alternatives for a directory-based cache coherence protocol in shared-memory multiprocessors

    Author : Håkan Grahn; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In shared-memory multiprocessors, caches are attached to the processors in order to reduce the memory access latency. To keep the memory consistent, a cache coherence protocol is needed. READ MORE
