  1. 1. Environmental Modelling Learning from Uncertainty

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : John M. Juston; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

    Abstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE

  2. 2. LES stochastic modelling of cavitation with its applications in OpenFOAM

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Boxiong Chen; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rayleigh-Plesset Equation; Cavitation; Modelling; Simulation; Eulerian Stochastic Field Method; OpenFOAM; Homogeneous Equilibrium Model;

    Abstract : Cavitation is a vaporization process that commonly happens in high-pressure injector nozzles nowadays. It has been shown by previous studies that cavitation has a significant influence on the subsequent atomization process, the quality of which would in turn heavily affect the process of combustion.

  3. 3. Groundwater Recharge in Crystalline Bedrock Processes, Estimation, and Modelling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Niclas Bockgård; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; groundwater recharge; bedrock; crystalline rocks; tracers; CFC; surface loading; loading efficiency; barometric effect; heterogeneity; stochastic modelling; Hydrologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi;

    Abstract : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. READ MORE

  4. 4. Stochastic modelling in disability insurance

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Björn Löfdahl; KTH.; [2013]

    Abstract : This thesis consists of two papers related to the stochastic modellingof disability insurance. In the first paper, we propose a stochastic semi-Markovian framework for disability modelling in a multi-period discrete-time setting. READ MORE

    Keywords : population model; stochastic population model; population dynamics; discrete time model; Beverton-Holt model; Skellam model; Hassell model; Ricker model; first principles; coupled map lattice; CML; area integral; square function; Mathematics; matematik;

    Abstract : This thesis consists of four papers, three papers about modelling animal populations and one paper about an area integral estimate for solutions of partial differential equations on non-smooth domains. The papers are: I. Å. Brännström, Single species population models from first principles. READ MORE
