    Sammanfattning : In this thesis multi-objective optimization is used to find Pareto fronts showing the set of optimized damping parameters of primary and secondary bogie suspensions. Special interests are put on requirements to enhance safety and comfort of a railway vehicle. LÄS MER

  4. 4. Optimal Design of District Energy Systems: a Multi-Objective Approach

    Författare :Cong Wang; Ivo Martinac; Birgit Müller; KTH; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; multi-objective optimization; robust design optimization; district energy; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The aim of this thesis is to develop a holistic approach to the optimal design of energy systems for building clusters or districts. The emerging Albano university campus, which is planned to be a vivid example of sustainable urban development, is used as a case study through collaboration with the property owners, Akademiska Hus and Svenska Bostäder.

  5. 5. Multi-objective CFD-based design method for axial compressors

    Författare :Lars R Ellbrant; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Q3D; Turbomachinery; Design; Meta-modeling; Optimization; CFD; Validation; Compressor; Transonic;

    Sammanfattning : Economic aspects such as reducing specific fuel consumption and ever growing environmental requirements on emissions and perceived noise levels are the major incentives in the pursuit to improve aircraft engines. The overall efficiency of the engine is a combination of propulsive efficiency and thermal efficiency. LÄS MER
