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

    Författare :Sofia Åberg; Matematisk statistik; []
    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

  3. 2. Comparative study of residue pellets from cane sugar and palm-oil industries with commercial wood pellets, applied in downdraft gasification

    Författare :Catharina Erlich; Torsten Fransson; Björn Zethraeus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy engineering; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Sammanfattning : While biomass utilization for energy conversion in the industrialized nations is being largely developed, highly efficient and environmentally friendly, many tropical countries still use biomass at low efficiencies and high emission levels. The main reasons for these gaps are both political and technological: the energy markets are different, the Gross National Product (GDP) differs widely, and the feedstock differs in form and conversion behaviour.

  4. 3. Statistical Analysis of Crests and Maxima in Gaussian Seas

    Författare :Jesper Rydén; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; physical oceanography; meteorology; Geofysik; programmering; aktuariematematik; fysisk oceanografi; meteorologi; Statistik; operationsanalys; actuarial mathematics; programming; Statistics; operations research; Mathematics; Matematik;

    Sammanfattning : An important problem in ocean engineering is to find distributions for characteristic wave parameters. For wind-generated water waves at deep water, a Gaussian distribution for the wave-surface elevation is considered a reasonable model. LÄS MER

  5. 4. Crossings and maxima in Gaussian fields and seas

    Författare :Eva Sjö; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; random waves; extremes; generalised Rice s formula; level-crossings; Gaussian random fields; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : In this thesis the focus is on crossing points in random fields and the probability distributions of various crossing variables in different applications. The crossing points are generalisations to random fields of points of level crossings by stochastic processes. LÄS MER

  7. 5. On Non Parametric Regression and Panel Unit Root Testing

    Författare :Xijia Liu; Rolf Larsson; Johan Lyhagen; Niklas Ahlgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : In this thesis, two different issues in econometrics are studied, the estimation of regression coefficients and the non-stationartiy analysis in a panel setting.Regarding the first topic, we study a set of measure of location-based estimators (MLBEs) for the slope parameter in a linear regression model with a single stochastic regressor.
