  1. 1. Road profile statistics relevant for vehicle fatigue

    Detta är en avhandling från Mathematical Statistics, Centre for Mathematical Sciences, Lund University

    Författare :Klas Bogsjö; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; Matematik; Mathematics; model evaluation; vehicle fatigue; stochastic processes; road roughness; Road profiles; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). LÄS MER

  3. 3. Approximation of Infinitely Divisible Random Variables with Application to the Simulation of Stochastic Processes

    Detta är en avhandling från Centre for Mathematical Sciences, Lund University

    Författare :Magnus Wiktorsson; Lund University.; Lunds universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; aktuariematematik; Stochastic differential equation; Infinitely divisible distribution; Type G distribution; Lévy process; Stochastic integral; Mathematical Statistics; Matematik; Mathematics; programming; actuarial mathematics; Statistik; operationsanalys; programmering;

    Sammanfattning : This thesis consists of four papers A, B, C and D. Paper A and B treats the simulation of stochastic differential equations (SDEs). The research presented therein was triggered by the fact that there were not any efficient implementations of the higher order methods for simulating SDEs. LÄS MER

  4. 4. Applications of Rice's formula in oceanographic and environmental problems

    Detta är en avhandling från KFS AB

    Författare :Sofia Åberg; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operations research; programming; actuarial mathematics; Statistik; operationsanalys; Statistics; Encountering waves; Gaussian random fields; Palm distributions; Rice s formula; wave statistics; level crossings; programmering; aktuariematematik;

    Sammanfattning : This thesis is based on five papers (A-E), all treating various applications of Rice's formula. The areas of application are oceanographic and environmental problems. The first three papers treat properties of encountering waves, that is, waves that a ship encounters while sailing on the ocean. LÄS MER

  5. 5. Spatial Statistics and Ancestral Recombination Graphs with Applications in Gene Mapping and Geostatistics

    Detta är en avhandling från Mathematical Statistics, Centre for Mathematical Sciences, Lund University

    Författare :Linda Werner Hartman; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetik; Genetics; cytogenetics; cytogenetik; genetic association analysis; ancestral recombination graph Generalized linear mixed models; kriging; bilinear interpolation; Gaussian Markov random fields; Statistics;

    Sammanfattning : This thesis explores models and algorithms in geostatistics and gene mapping. The first part deals with the use of computationally effective lattice models for inference of data with a continuous spatial index. LÄS MER
