  1. 6. Microstructural design and optimization of Nickel-based superalloys for gas turbines

    University essay from KTH/Materialvetenskap

    Author : Anirudh Vasishta; [2023]
    Keywords : Nickel- based superalloys; gamma prime γ′ size calculations; Nickelbaserade superlegeringar; gamma prime γ′ storleksberäkningar;

    Abstract : One of the main sources of energy in this modern world is the gas turbine.  They reach extremely high working temperatures at peak capacity and hence require materials that can withstand the same. READ MORE

  3. 7. Unlocking the Potential of AI-driven Circular Business Model Innovation : A case study of an industrial symbiosis

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Björn Tomas Minde; Niklas Bäcklund; [2023]
    Keywords : Artificial intelligence; Circular business model; Circular business model innovation; Circular economy; Industrial symbiosis; Artificiell intelligens; Cirkulär affärsmodell; Cirkulär affärsmodell innovation; Cirkulär ekonomi; Industriell symbios;

    Abstract : Purpose – This study aims to explore and provide empirical insights into AI-driven circular business model innovation (CBMI) in industrial symbiosis. In doing so, it addresses the knowledge gap regarding how industrial companies can use AI to amplify circular business models and facilitate AI-driven circular innovation. READ MORE

  4. 8. Design and implementation of an energy harvesting system in a prosthetic limb

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ódinn K. Rúnarsson; [2023]
    Keywords : Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Abstract : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. READ MORE

  5. 9. Investigation of coarse-grid CFD approach for nuclear engineering application

    University essay from KTH/Fysik

    Author : Michela Casarella; [2023]
    Keywords : Thermal-hydraulics; Nuclear reactor; CFD; Sub-channel; Coarse-grid; Turbulence; Pressure drop; Termisk-hydraulik; kärnreaktor; CFD; underkanal; grovkornigt nät; turbulens; tryckfall;

    Abstract : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

  6. 10. Biologisk bekämpning av potatiscystnematoder : några biologiska bekämpningsorganismer och deras potential för svenskt bruk

    University essay from SLU/Dept. of Ecology

    Author : Sabina Juhlin Munoz; [2023]
    Keywords : tillsättande biologisk bekämpning; Globodera; potatiscystnematoder; svampar; bakterier; parasitism; antibios; Trichoderma harzianum; Bacillus thuringiensis;

    Abstract : Potatiscystnematoderna (PCN) Globodera pallida (vit potatiscystnematod) och G. rostochiensis (gul potatiscystnematod) är sedentära endoparasiter på potatis som kan orsaka stora skördeförluster i potatisodlingar. Båda arterna av PCN är även klassade som karantänskadegörare i Sverige. READ MORE
