  1. 11. Wire and Arc Additive Manufacturing : Topology Optimised Vehicle Component

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Malte Petersson; [2022]
    Keywords : Wire and Arc Additive Manufacturing; Additive Manufacturing; WAAM; AM; Overhang; Cooling times; Simulation; Welding;

    Abstract : Wire and arc additive manufacturing (WAAM) is a manufacturing method using a numerical controlled motion system and a welding system to additively manufacture three dimensional components. The motion system is programmed from three dimensional computer aided design model data (3D-CAD) of the intended geometry which is then sliced in to layers and welded on additively. READ MORE

  3. 12. Real time estimations of kLa and viscosity in a fermentation pilot plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Arvid Norberg; [2022]
    Keywords : Oxygen transfer; Viscosity; Fermentation; Biotechnology; Direct method; kLa; OUR; DO; Online monitoring; Soft sensor; Fungus; Fungal fermentation; A. oryzae; A. niger; Herschel-Bulkley; Power law; Shear thinning; Novozymes; Enzymes; Technology and Engineering;

    Abstract : Fermentation is a process that utilizes live microorganisms to produce different biological products such as enzymes. The oxygen mass transfer rate is often the limiting factor in aerobic fermentations and thereby an important process parameter. READ MORE

  4. 13. Identification of spectral features differentiating fungal strains in infrared absorption spectroscopic images

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Dejan Stancevic; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There are many unknowns regarding the interaction between fungi and their surroundings. In this project, we took a closer look at hyperspectral images of several fungal strains on two different substrates. The project mainly consisted of developing a code for the classification of fungal strains and the extraction of information from it. READ MORE

  5. 14. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

    University essay from

    Author : Manroop Bhattasali; [2022]
    Keywords : Catalytic converter; packaging mats; support mats; compression; friction; hyperelastic; hyperfoam; viscoelastic; canning; finite element;

    Abstract : The increase of new and ever more stringent emission legislation has brought about with it a surge in the demand for more sustainable automotive solutions. This has particularly been the case for automobiles, including heavy-duty vehicles like trucks and buses, with internal combustion engines, which now require the design and manufacturing of more durable and reliable components.

  6. 15. Investigation of Methods to Improve PZT Sol-Gel Deposition Process for Energy Harvesting Applications

    University essay from KTH/Hälsoinformatik och logistik

    Author : Mikael Granberg; [2022]
    Keywords : PZT; sol-gel; self-polarization; seed layer; titanium oxidation; PZT; sol-gel; självpolarisering; seedlager; titanoxidering;

    Abstract : The purpose of this work was to investigate ways to modify Silex sol-gel deposition of PZT (PbZrxTi(1-x)O3, Lead Zirconate Titanate) in order to improve its properties for energy harvesting applications. A number of methods to improve the figure of merit for energy harvesting (FOM= e312/ε), cause self-polarization, increase lifetime, reduce cost, increase throughput or simplify processing were tested.
