  1. 1. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints

    Author : Nilsson Olof; Lennart Söder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Integer Constraints; Lagrange relaxation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... READ MORE

  2. 2. Analysis, synthesis and application of automaton-based constraint descriptions

    Author : María Andreína Francisco Rodríguez; Justin Pearson; Pierre Flener; Christopher Jefferson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; constraint programming; constraint predicates; global constraints; automata; automaton-described constraint predicates; automaton-induced constraint decompositions; implied constraints; time-series constraints; transducers; automaton invariants; Computer Science; Datavetenskap;

    Abstract : Constraint programming (CP) is a technology in which a combinatorial problem is modelled as a conjunction of constraints on variables ranging over given initial domains, and optionally an objective function on the variables. Such a model is given to a general-purpose solver performing systematic search to find constraint-satisfying domain values for the variables, giving an optimal value to the objective function.

  4. 4. On Models and Methods for Global Optimization of Structural Topology

    Author : Mathias Stolpe; KTH; []
    Keywords : topology optimization; global optimization; stress constraints; linear programming; mixed integer programming; branch-and-bound;

    Abstract : This thesis consists of an introduction and sevenindependent, but closely related, papers which all deal withproblems in structural optimization. In particular, we considermodels and methods for global optimization of problems intopology design of discrete and continuum structures. READ MORE

  5. 5. On Methods for Discrete Topology Optimization of Continuum Structures

    Author : Mats Werme; Krister Svanberg; Wolfgang Achtziger; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Topology optimization; Stress constraints; Sensitivity calculations; Neighbourhood search methods; Sequential integer programming; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : This thesis consists of an introduction and seven appended papers. The purpose of the introduction is to give an overview of the field of topology optimization of discretized load carrying continuum structures. READ MORE
