  3. 17. Attention-deficit/hyperactivity disorder : alterations of motor behaviour and dopaminergic transmission

    Författare :Aurelija Jucaite; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :AD HD; DCD; neurodevelopmental disorder; PET; dopamine transporter; dopamine D2 receptors; raclopride; striatum; midbrain; anticipatory postural adjustments;

    Sammanfattning : Altered catecholaminergic neurotransmission in the brain has long been thought to be of importance in the regulation of motor behavior and cognitive performance in children who had symptoms of distractability, impulsivity and clumsiness. The dopamine theory of AD/HD has mainly been substantiated by: i) the effects of psychostimulants, which target the dopamine transporter (DAT), and thereby reduce impulsiveness and inattentiveness, increase the striatal cerebral blood flow and functional activity, and ii) the evidence from linkage studies associating the AD/HD syndrome with allelic variations of genes encoding the dopamine transporter and, possibly, the dopamine D4 receptors.

  4. 18. Learning Sequential Decision Rules in Control Design: Regret-Optimal and Risk-Coherent Methods

    Författare :Matias I. Müller; Cristian R. Rojas; Håkan Hjalmarsson; Tom Oomen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Engineering sciences deal with the problem of optimal design in the face of uncertainty. In particular, control engineering is concerned about designing policies/laws/algorithms that sequentially take decisions given unreliable data. This thesis addresses two particular instances of optimal sequential decision making for two different problems. LÄS MER

  5. 19. Enhancing Aircraft Conceptual Design using Multidisciplinary Optimization

    Författare :Daniel Raymer; KTH; []
    Nyckelord :aircraft design MDO optimization fighter UAV transport;

    Sammanfattning : Research into the improvement of the Aircraft ConceptualDesign process by the application of MultidisciplinaryOptimization (MDO) is presented. Aircraft conceptual designanalysis codes were incorporated into a variety of optimizationmethods including Orthogonal Steepest Descent (full-factorialstepping search), Monte Carlo, a mutation-based EvolutionaryAlgorithm, and three variants of the Genetic Algorithm withnumerous options.
