  1. 1. Automatic parallel parking : park assist systems for passenger vehicles

    Författare :Pär Degerman; Linköpings universitet; []

    Sammanfattning : This thesis discusses how the problem of parking a passenger car can be solved. There ane numerous obstacles when creating a fully or semi automated system for assisting the parking maneuver. The obstacles range from unobtrusive Man Machine Interface issues to robust algorithms for finding features in sensor data. LÄS MER

    Sammanfattning : Methods for performing large-scale parallel Molecular Dynamics(MD) simulations are investigated. A perspective on the field of parallel MD simulations is given. Hardware and software aspects are characterized and the interplay between the two is briefly discussed. LÄS MER

  3. 3. Efficient Parallel Algorithms for Combinatorial Problems

    Författare :Oscar Garrido Gómez; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics; Data- och systemvetenskap; computer technology; Systems engineering; matchings.; independent sets; graphs; parallel algorithms;

    Sammanfattning : This thesis is concerned with the design of efficient parallel algorithms for some optimization graph problems. A subset S of vertices or edges in a graph G is said to be maximum with respect to a property if, among all the subsets of G having this property, S is one having the largest cardinality. LÄS MER

  5. 5. Phase transitions in novel superfluids and systems with correlated disorder

    Författare :Hannes Meier; Mats Wallin; Asle Sudbø; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; phase transitions; critical phenomena; spin models; quantum phase transitions; quantum fluids; superfluidity; superconductivity; disordered systems; Bose glass; dirty bosons; vortex pinning; statistical mechanics; Monte Carlo simulation; Wolff algorithm; classical worm algorithm; Wang-Landau algorithm; Physics; Fysik;

    Sammanfattning : Condensed matter systems undergoing phase transitions rarely allow exact solutions. The presence of disorder renders the situation  even worse but collective Monte Carlo methods and parallel algorithms allow numerical descriptions. LÄS MER
