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

    Författare :Oskar Hagberg; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; Statistik; operationsanalys; aktuariematematik; programming; operations research; Matematik; Statistics; sea elevation; Mathematics; asymptotic expansions; wave crest hight distribution; Saddle point approximations; Crossing rate; programmering;

    Sammanfattning : 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. LÄS MER

  3. 2. Modelling Sea Surface Dynamics Using Crossing Distributions

    Författare :Anastassia Baxevani; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistik; actuarial mathematics; programmering; operations research; Statistics; velocities; global maximum; Rice formula; level crossings; Gaussian random fields; programming; aktuariematematik; operationsanalys;

    Sammanfattning : The thesis deals mainly with modelling sea surface dynamics. We consider two different scales. LÄS MER

  4. 3. Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture

    Författare :Ellika Faust; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation genetics; population genetics; aquaculture escapee; hybridisation; corkwing wrasse; lumpfish; cleaner fish translocation; sea lice; range expansion; fishery management;

    Sammanfattning : Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control in salmon aquaculture, often considered to be more environmentally friendly than other delousing methods. LÄS MER

  5. 4. Crossing the river by feeling the stones : Approaches to Sustainable Urban Development in China

    Författare :Hongling Liu; Björn Frostell; Dick Urban Vestbro; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : China already has the highest numbe of,and largest cities in its history. According to recent statistics, Chinese cities were home to 52.6% of China’s total population at the end of 2012. LÄS MER

  7. 5. Ocean circulation in the Amundsen Sea, West Antarctica

    Författare :Ola Kalén; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean; currents; icebergs; remote sensing; ocean model;

    Sammanfattning : The increase of mass loss from the Antarctic Ice Sheet is a significant contribution to global sea level rise. The most rapid changes are occurring in the Amundsen Sea area, where the thinning of the floating glaciers is assumed to be driven by the ocean. LÄS MER
