  1. 1. Digital Valve-Jet Printing of Chitosan Ink on Cotton Fabric for Antibacterial and Comfort Properties

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Media Haghi; [2023]
    Keywords : Chitosan; Digital printing; Valve-jet printing; ChromoJet printer; Antibacterial textile; cotton fabric;

    Abstract : Throughout history, the spread of microorganisms has caused much damage including infectious diseases and deaths. Ever since humans realized the impact of bacteria especially on population health many efforts have been done to combat the spread of pathogens. READ MORE

  3. 2. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  4. 3. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Kent Nystedt; [2022]
    Keywords : Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Abstract : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. READ MORE

  5. 4. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Musole Kambita; [2022]
    Keywords : Cylindrical steel tanks; yield strength; carbon steel; high strength steel; design load; buckling; stiffening rings; Finite Element Method FEM ; Linear Elastic Bifurcation LBA ; and Geometrically and Materially Nonlinear Analysis with Imperfections GMNIA .;

    Abstract : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. READ MORE

  6. 5. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Amir Avdic; Kishore-Babu Vejendla; [2022]
    Keywords : viscous losses; hydrostatic bearing; hydrodynamics; thin oil film.; Viskösa förluster; generator; hydrostatiska lager; hydrodynamik; tunn oljefilm.;

    Abstract : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it. READ MORE
