  2. 1. Optimal thinning : a theoretical investigation on individual-tree level

    Author : Peter Fransson; Åke Brännström; Ola Lindroos; Oskar Franklin; Per Lundberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest management; Simulation; Optimization; Spatially explicit model; Individual-based model;

    Abstract : Paper I: In paper I, we asked how a tree should optimally allocate its resources to maximize its fitness. We let a subject tree grow in an environment shaded by nearby competing trees. The competitors were assumed to have reached maturity and had stopped growing, thus creating a static light environment for the subject tree to grow in. READ MORE

  4. 2. Optimal Stopping and Model Robustness in Mathematical Finance

    Author : Henrik Wanntorp; Johan Tysk; Svante Janson; Boualem Djehiche; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimal stopping; model robustness; American options; free boundary problems; hedging; option pricing; Mathematical statistics; Matematisk statistik;

    Abstract : Optimal stopping and mathematical finance are intimately connected since the value of an American option is given as the solution to an optimal stopping problem. Such a problem can be viewed as a game in which we are trying to maximize an expected reward. READ MORE

  5. 3. Optimal design for dose-finding studies

    Author : Renata Eirini Tsirpitzi; Frank Miller; Kirsten Schorning; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bivariate model; distortion; drug combination; Elfving set; Emax model; Fedorov algorithm; mixed effects models; optimal experimental design; Statistics; statistik;

    Abstract : One of the most complex tasks during the clinical development of a new drug is to find a correct dose. Optimal experimental design has as a goal to find the best ways to perform an experiment considering the available resources and the statistical model. Optimal designs have already been used to determine the design of dose-finding studies. READ MORE

  6. 4. Optimal Control and Model Reduction of Nonlinear DAE Models

    Author : Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAE Models; Optimal Control; Model Reduction; Automatic control; Reglerteknik;

    Abstract : In this thesis, different topics for models that consist of both differential and algebraic equations are studied. The interest in such models, denoted DAE models, have increased substantially during the last years. READ MORE

  7. 5. Effective Techniques for Stateless Model Checking

    Author : Stavros Aronis; Konstantinos Sagonas; Bengt Jonsson; Patrice Godefroid; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Concurrent; Parallel; Model Checking; Partial Order Reduction; Dynamic Partial Order Reduction; DPOR; Sleep Set Blocking; Source Sets; Source DPOR; Wakeup Trees; Optimal DPOR; Observers; Verification; Bounding; Exploration Tree Bounding; Testing; Erlang; Concuerror; Protocol; Chain Replication; CORFU; Computer Science; Datavetenskap;

    Abstract : Stateless model checking is a technique for testing and verifying concurrent programs, based on exploring the different ways in which operations executed by the processes of a concurrent program can be scheduled. The goal of the technique is to expose all behaviours that can be a result of scheduling non-determinism. READ MORE
