  1. 6. Small-Scale Decentralized Energy Systems optimization and performance analysis

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Sara Ghaem Sigarchian; KTH.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

    Sammanfattning : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. LÄS MER

  2. 7. Asynchronous Algorithms for Large-Scale Optimization Analysis and Implementation

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Arda Aytekin; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; optimization; asynchronous algorithms; algorithms; parallel algorithms; large-scale; big data; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis proposes and analyzes several first-order methods for convex optimization, designed for parallel implementation in shared and distributed memory architectures. The theoretical focus is on designing algorithms that can run asynchronously, allowing computing nodes to execute their tasks with stale information without jeopardizing convergence to the optimal solution.

  3. 8. On optimization of natural convection flows

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Clio Saglietti; KTH.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural convection cooling; topology optimization; flow optimization; heat sink; conjugate heat transfer; differentially heated cavity; optimal initial disturbances; adjoint optimization;

    Sammanfattning : Two different techniques are presented for enhancing the thermal  performance of natural convection cooled heat sinks. The physics is  described by solving the conjugate heat transfer problem with a  spectral element method. The temperature distribution is computed in  two sub-domains, whose solution is then conjugated. LÄS MER

  4. 9. Optimization of Compressive Crushing

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Elisabeth Lee; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cone Crusher; Modeling; Compressive Crushing; Implementation; Optimization;

    Sammanfattning : With almost all infrastructures being dependent on the supply of crushed rock materials,minerals, and ores, it is fair to say that the foundation of modern society is literally built uponthese materials. As society continues to develop and standards of living progressivelyincrease, the subsequent growing demand for crushed rock materials, minerals, and ores willresult in a need for improving the performance and efficiency of rock crushing equipment.

  5. 10. Product Configuration from a Mathematical Optimization Perspective

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Peter Lindroth; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; multiple objectives; platform-based products; heavy-duty trucks; configuration management; categorical variables; global optimization; robustness;

    Sammanfattning : The optimal truck configuration for a certain customer is very specific and depends on for what transport mission and in which operating environment the truck is to be used. In addition, the customers normally specify other feature requirements ranging from visual appearance to advanced driver support systems. LÄS MER
