  1. 16. Models and Critical Maneuvers for Road Vehicles

    Detta är en avhandling från Linköping University Electronic Press

    Författare :Kristoffer Lundahl; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As manufacturers are pushing their research and development toward more simulation based and computer aided methods, vehicle dynamics modeling and simulation become more important than ever. The challenge lies in how to utilize the new technology to its fullest, delivering the best possible performance given certain objectives and current restrictions. LÄS MER

  2. 17. Optimal Sequential Decisions in Hidden-State Models

    Detta är en avhandling från Uppsala : Department of Mathematics, Uppsala University

    Författare :Juozas Vaicenavicius; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sequential analysis; optimal stopping; optimal liquidation; drift uncertainty; incomplete information; stochastic filtering;

    Sammanfattning : This doctoral thesis consists of five research articles on the general topic of optimal decision making under uncertainty in a Bayesian framework. The papers are preceded by three introductory chapters.Papers I and II are dedicated to the problem of finding an optimal stopping strategy to liquidate an asset with unknown drift. LÄS MER

    Detta är en avhandling från Uppsala : Department of Mathematics, Uppsala University

    Författare :Vilhelm Verendel; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Backward Induction; Bayesian analysis; Finitely Repeated Prisoners Dilemma; Cooperation; Fermi Paradox; Learning; Climate negotiations; Catastrophic risk;

    Sammanfattning : Our world presents us with dangers and opportunities. Some of these dangers and opportunities are easier to handle if two or more individuals learn to cooperate. This thesis contributes five papers about cooperation, learning and catastrophic risk. LÄS MER

  4. 19. Toward Sequential Data Assimilation for NWP Models Using Kalman Filter Tools

    Detta är en avhandling från Stockholm : Department of Mathematics, Stockholm University

    Författare :Jelena Bojarova; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-Gaussian state space models; Kalman filtering; ETKF; 3D-Var; data assimilation; NWP; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The aim of the meteorological data assimilation is to provide an initial field for Numerical Weather Prediction (NWP) and to sequentially update the knowledge about it using available observations. Kalman filtering is a robust technique for the sequential estimation of the unobservable model state based on the linear regression concept. LÄS MER

  5. 20. Population dynamics and demography - inferences from stochastic models

    Detta är en avhandling från Department of Ecology, Lund University

    Författare :Jonas Knape; Lunds universitet.; Lund University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Time series analysis of population abundances is a common approach to making inferences about population dynamics, and especially for estimating density dependence. Traditionally the impact of potential errors in observations or measurements of the abundances on inference has been ignored. LÄS MER
