  2. 1. Optimisation of Long-Term Industrial Planning

    Author : Peter Forsberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimisation under uncertainty; Transition strategy optimisation; Investment strategies; Multi-objective decision making;

    Abstract : In this thesis, long-term optimisation methods for industrial transition processes have beendeveloped, taking monetary and environmental considerations into account. Two different methods forinvestment optimisation have been developed. READ MORE

  4. 2. The Story of Phosphorus : Sustainability implications of global phosphorus scarcity for food security

    Author : Dana Cordell; Stuart White; Jan-Olof Drangert; Julie Wilk; Johan Rockström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; global phosphorus scarcity; peak phosphorus; global food security; sustainable resource use; food production and consumption system; transdisciplinary; systems thinking; global fosforbrist; peak fosfor; global matsäkerhet; hållbar resursanvändning; system för produktion och konsumtion av mat; transdisciplinaritet; systemtänkande; Water in nature and society; Vatten i natur och samhälle;

    Abstract : The story of phosphorus began with the search for the philosopher’s stone, and centuries later the critical role of phosphorus in soil fertility and crop growth was highlighted. Eventually, phosphorus was implicated in the global environmental challenge of eutrophication. READ MORE

  5. 3. Long-Term Localization for Self-Driving Cars

    Author : Erik Stenborg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sequential semantic localization; self-driving; localization;

    Abstract : Long-term localization is hard due to changing conditions, while relative localization within time sequences is much easier. To achieve long-term localization in a sequential setting, such as, for self-driving cars, relative localization should be used to the fullest extent, whenever possible. READ MORE

  6. 4. Strategies, Methods and Tools for Solving Long-term Transmission Expansion Planning in Large-scale Power Systems

    Author : Desta Zahlay Fitiwi; Lennart Söder; Michel Rivier; Fernando de Cuadra; Andres Ramos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission expansion planning; uncertainty and variability; optimization; stochastic programming; moments technique; clustering; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Driven by a number of factors, the electric power industry is expected to undergo a paradigm shift with a considerably increased level of variable energy sources. A significant integration of such sources requires heavy transmission investments over geographically wide and large-scale networks. READ MORE

  7. 5. Global stability analysis of three-dimensional boundary layer flows

    Author : Mattias Brynjell-Rahkola; Dan Henningson; Philipp Schlatter; Ardeshir Hanifi; Spencer Sherwin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic stability; transition to turbulence; global analysis; boundary layers; roughness; laminar flow control; Stokes Laplace preconditioner; optimal forcing; crossflow vortices; Ginzburg-Landau; Falkner-Skan-Cooke; Blasius; lid-driven cavity;

    Abstract : This thesis considers the stability and transition of incompressible boundary layers. In particular, the Falkner–Skan–Cooke boundary layer subject to a cylindrical surface roughness, and the Blasius boundary layer with applied localized suction are investigated. READ MORE
