  1. 1. Understanding Weather effects on, in, and from large Herbivore Population Dynamics

    Detta är en avhandling från Department of Ecology, Lund University

    Författare :Lena Månsson; Lund University.; Lunds universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monitoring; management; data collection; Ecology; Ekologi; indirect effects; vegetation; modeling; time series analysis; precipitation; weather; population dynamics; Large herbivores;

    Sammanfattning : Large herbivores are monitored for various reasons in many areas around the world. Data from such monitoring can be of varying degree of detail and extent. Several studies have shown that we need extensive amounts of data with a high degree of detail to be able to understand anything from it. LÄS MER

  2. 2. Space Weather Physics: Dynamic Neural Network Studies of Solar Wind-Magnetosphere Coupling

    Detta är en avhandling från Lund Observatory, Lund University

    Författare :Jian-Guo Wu; Lund University.; Lunds universitet.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; kosmisk kemi; rymdvetenskap; Astronomi; cosmic chemistry; solar wind; space weather; magnetosphere; solar wind-magnetosphere coupling; geomagnetic activity; geomagnetic storms; predictions; modeling; neural networks; space research; Astronomy; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Fysicumarkivet A:1997:Wu;

    Sammanfattning : This thesis presents studies of solar wind-magnetosphere coupling using dynamic neural networks in combination with statistically correlative analysis. The primary contribution of the thesis is dynamic neural network models that can be implemented for near real-time predictions of geomagnetic storms from the solar wind alone. LÄS MER

  3. 3. Modeling stormwater transport through unsaturated green roof substrates

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Sammanfattning : In recent decades there has been an increase in research regarding green roofs and similar technologies. This increased interest is driven by the requirements of urban development and its effects both on humans and the environment. LÄS MER

  4. 4. Modelling Weather Dynamics for Weather Derivatives Pricing

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Emanuel Evarest Sinkwembe; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis focuses on developing an appropriate stochastic model for temperature dynamics as a means of pricing weather derivative contracts based on temperature. There are various methods for pricing weather derivatives ranging from simple one like historical burn analysis, which does not involve modeling the underlying weather variable to complex ones that require Monte Carlo simulations to achieve explicit weather derivatives contract prices, particularly the daily average temperature (DAT) dynamics models.

  5. 5. Probabilistic modeling in sports, finance and weather

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jan Lennartsson; Göteborgs universitet.; Gothenburg University.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; Game theory; Team sport tactics; Modern portfolio theory; Gaussian fields;

    Sammanfattning : In this thesis, we build mathematical and statistical models for a wide variety of real world applications. The mathematical models include applications in team sport tactics and optimal portfolio selection, while the statistical modeling concerns weather and specifically precipitation. LÄS MER
