  1. 1. Reinforcement in Biology Stochastic models of group formation and network construction

    Detta är en avhandling från Uppsala : Department of Mathematics

    Författare :Qi Ma; Uppsala universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reinforcement in biology; merge and split model; preferential attachment; reinforced random walk; network construction; shortest path problem; transport networks; ant algorithm; slime mould; physarum polycephalum; speed-accuracy tradeoff.; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Sammanfattning : Empirical studies show that similar patterns emerge from a large number of different biological systems. For example, the group size distributions of several fish species and house sparrows all follow power law distributions with an exponential truncation. LÄS MER

  3. 3. Reinforcement in Tailor-made Concrete Structures

    Detta är en avhandling från Chalmers University of Technology

    Författare :David Fall; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; Byggproduktionsteknik; Building manufacturing engineering; Övrig samhällsbyggnadsteknik och arkitektur; Other civil engineering and architecture; Konstruktionsteknik; Construction engineering; Tailor-made concrete structures; Geometrically complex structures; Reinforcement alternatives; Steel fibre reinforcement; Automated production;

    Sammanfattning : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. LÄS MER

  5. 5. Computational Modeling of the Basal Ganglia Functional Pathways and Reinforcement Learning

    Detta är en avhandling från Stockholm : Numerical Analysis and Computer Science (NADA), Stockholm University

    Författare :Pierre Berthet; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computational neuroscience; modelisation; reinforcement learning; basal ganglia; dopamine; datalogi; Computer Science;

    Sammanfattning : We perceive the environment via sensor arrays and interact with it through motor outputs. The work of this thesis concerns how the brain selects actions given the information about the perceived state of the world and how it learns and adapts these selections to changes in this environment.
