  1. 11. Modeling and Optimization of Reversed-Phase Chromatography : Effects of Modulators and Temperature

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Karolina Arkell; Lunds universitet.; Lund University.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reversed-phase chromatography; Hydrophobic interaction chromatography; Mechanistic modeling; INSULIN; KCl; Ethanol; Temperature; Multi-objective optimization; Constraint; Solubility;

    Abstract : Many widespread diseases, such as diabetes, various types of cancer, and aggressive versions of influenza, are treated or prevented with biopharmaceuticals. Biopharmaceuticals are drugs that are based on proteins, peptides, antibodies, attenuated viruses (vaccines), and other biomolecules that are synthesized predominately in bacteria, yeast, and mammalian cells.

  2. 12. Energy Quality Management for Building Clusters and Districts Using a Multi-Objective Optimization Approach

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lu Hai; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : As society develops, energy needs and the warnings of global warming have become main areas of focus in many areas of human life. One such aspect, the building sector, needs to take responsibility for a significant portion of energy use. Researchers need to concentrate on applying innovative methods for controlling the growth of energy use. READ MORE

  3. 13. Optimal Estimation of Grain Orientation in an Anisotropic Weld by Ultrasonic Techniques

    University dissertation from Chalmers University of Technology

    Author : Qingwei Liu; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fastkroppsmekanik; Solid mechanics; anisotropic weld model; 2D ray tracing; ultrasonic probe model; nonlinear optimization; multi-objective genetic algorithm;

    Abstract : Grain orientation in an anisotropic weld highly influences ultrasound paths and thus is a significant parameter when making simulations of ultrasonic testing of anisotropic welds. Though each weld is thought to be unique in its structure, the common procedure in modeling is to prescribe the grain orientation in a weld based on limited experience. READ MORE

    University dissertation from Chalmers University of Technology

    Author : Kaijia Han; Chalmers tekniska högskola.; Chalmers University of Technology.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningsmekanik; Fluid mechanics; optimization; propeller geometry; full scale; Hamburg test case; cavitation; verification; correction; iteration number; grid density; efficiency; pressure fluctuation; delivered power; RANS;

    Abstract : The work presented in this thesis includes two stages in a research project at the Rolls-Royce University Technology Center (UTC) at Chalmers Technology University. The objective of the project is to develop an optimization technique for ship/propeller interaction. READ MORE

  5. 15. Slab Frame Bridges Structural Optimization Considering Investment Cost and Environmental Impacts

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Majid Solat Yavari; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slab frame bridge; Structural design; Cost optimization; Optimization of environmental impact; Life cycle assessment; Genetic algorithm; Pattern search method; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : This research encompasses the automated design and structural optimization of reinforced concrete slab frame bridges, considering investment costs and environmental impacts. The most important feature of this work is that it focusses on realistic and complete models of slab frame bridges rather than on optimization of only individual members or sections of a bridge.
