  1. 1. Feature Informativeness, Curse-of-Dimensionality and Error Probability in Discriminant Analysis

    Author : Tatjana Pavlenko; Mittuniversitetet.; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; Multivariate analysis; Statistics; feature selection; Discriminant analysis; feature informativeness; growing dimension assymptotics; operations research; operationsanalys; programmering; aktuariematematik; programming; actuarial mathematics; Statistik;

    Abstract : This thesis is based on four papers on high-dimensional discriminant analysis. Throughout, the curse-of-dimensionality effect on the precision of the discrimination performance is emphasized. A growing dimension asymptotic approach is used for assessing this effect and the limiting error probability are taken as the performance criteria. READ MORE

  3. 3. Stochastic Modeling and Operational Optimization in District Heating Systems

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Lars Arvastson; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; Statistik; programming; operations research; Statistics; Matematik; optimization; Mathematics; simulation; prediction; District heating; grey-box modeling; operationsanalys; programmering; aktuariematematik; Systems engineering; computer technology; Data- och systemvetenskap;

    Abstract : Operation of a district heating system is accomplished via a sequence of decisions by the operators controlling the system. These decisions are based on expectations of conditions in the system that are not known at decision time. READ MORE

  4. 4. Road profile statistics relevant for vehicle fatigue

    University dissertation from Mathematical Statistics, Centre for Mathematical Sciences, Lund University

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

    Abstract : 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). READ MORE

  5. 5. Asymptotic Expansions of Crossing Rates of Stationary Random Processes

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Oskar Hagberg; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; actuarial mathematics; operationsanalys; aktuariematematik; programming; operations research; Matematik; Statistics; sea elevation; Mathematics; asymptotic expansions; wave crest hight distribution; Saddle point approximations; Crossing rate; programmering;

    Abstract : The crossing rate of a stationary random process is a valuble tool when studying crest hight distributions and maxima of sea level elevation. This thesis considers two approximation techinques for cases when the crossing rate cannot be exactly computed. READ MORE
