  1. 11. Modelling Human Developmental Hematopoiesis. Towards in vitro Generation of Human Hematopoietic Stem Cells

    Författare :Carolina Guibentif; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human pluripotent stem cells; Embryonic Development; endothelial-to-hematopoietic transition; Hematopoiesis;

    Sammanfattning : The possibility to manufacture hematopoietic stem cells (HSCs) in the laboratory would provide an indefinite source of cells for patients requiring bone marrow transplantation. Moreover, combined with the progress in gene editing techniques, it would provide a novel platform for gene and cell replacement therapies for a range of currently incurable congenic and acquired disorders.

  3. 12. On Reference Architectures for Development of Flexible Cell Control Systems

    Författare :Per Gullander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shop-floor control; generic modelling; cell control; flexible manufacturing systems; modelling framework; reference architecture; computer-integrated manufacturing;

    Sammanfattning : Industrial problems of inflexible and expensive shop-floor control systems were analysed. The principal causes are suggested to be poor development methodology, poor tools used for development and implementation, and poor knowledge on how such systems are best built. LÄS MER

  4. 13. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems

    Författare :Jens Pålsson; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; Gases; fluid dynamics; plasmas; plasma; hydraulik; Maskinteknik; vibration and acoustic engineering; hydraulics; vacuum technology; Modelling; Mechanical engineering; Solid oxide fuel cell; Hybrid system; Gaser; fluiddynamik;

    Sammanfattning : Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. LÄS MER

  5. 14. Validated Modelling of Electrochemical Energy Storage Devices

    Författare :Niklas Mellgren; Anders Dahlkild; Michael Vynnycky; Jesper Oppelstrup; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium ion battery; polymer electrolyte fuel cell; modelling; model validation; parameter fitting; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : This thesis aims at formulating and validating models for electrochemical energy storage devices. More specifically, the devices under consideration are lithium ion batteries and polymer electrolyte fuel cells. A model is formulated to describe an experimental cell setup consisting of a LixNi0.8Co0. LÄS MER

  7. 15. Modelling and experimental investigation of the porous nickel anode in the molten carbonate fuel cell

    Författare :Mari Sparr; Göran Lindbergh; Kas Hemmes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; molten carbonate fuel cell; MCFC; mechanism; cell modelling; porous electrode; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : The thesis is focussed on the performance of the fuel cell and the design of the cell for operation with natural gas and renewable fuels, e.g. biogas or gasified biomass. The performance is one of the important issues for the development and commercialisation of fuel cell stacks. LÄS MER
