    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GN model; optimization; resource allocation; Flexible-grid optical network; heuristic algorithm; DCNs; regenerator location;

    Sammanfattning : The theme of this thesis is the optimization, design, and analysis of flexible-grid optical networks that are constrained by physical-layer impairments (PLIs). We consider three flexible-grid network scenarios. LÄS MER

  3. 12. Spatio-temporal forecasting and optimization for integration of solar energy in urban energy systems

    Författare :Dennis van der Meer; Joakim Widén; Pierre Pinson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forecasting; photovoltaic; electricity use; net load; probabilistic; multivariate; optimization; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : The increasing penetration of non-dispatchable renewable energy sources such as photovoltaic (PV) systems in the electricity generating mix poses challenges to the operational performance of the power system. On the demand side, advanced schemes that increase the flexibility of customer loads and the increase in electrification are set to noticeably alter electricity demand. LÄS MER

  4. 13. Metaheuristic Algorithms for Spatial Multi-Objective Decision Making

    Författare :Olive Niyomubyeyi; Centrum för geografiska informationssystem (GIS-centrum); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geographic Information System GIS ; Multi-Objective Optimization MOO ; Spatial Decision Making; Metaheuristic Algorithms; Disaster management; Urban planning;

    Sammanfattning : Spatial decision making is an everyday activity, common to individuals and organizations. However, recently there is an increasing interest in the importance of spatial decision-making systems, as more decision-makers with concerns about sustainability, social, economic, environmental, land use planning, and transportation issues discover the benefits of geographical information.

  7. 15. Data Assimilation in Fluid Dynamics using Adjoint Optimization

    Författare :Johan Lundvall; Vladimir Kozlov; Per Weinerfelt; Matts Karlsson; Anders Szepessy; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data assimilation; Inverse problem; Adjoint optimization; Burgers equation; nonlinear; Landweber; Initial pressure; Euler flow; Applied mathematics; Tillämpad matematik;

    Sammanfattning : Data assimilation arises in a vast array of different topics: traditionally in meteorological and oceanographic modelling, wind tunnel or water tunnel experiments and recently from biomedical engineering. Data assimilation is a process for combine measured or observed data with a mathematical model, to obtain estimates of the expected data. LÄS MER
