  1. 1. The Impact of Global Warming on Wind Power Potential in the Greater Horn of Africa

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Bromwel Apondi; [2023-08-17]
    Keywords : Near-surface wind speed; the Greater Horn of Africa; ERA5; Wind power density; CORDEX-Africa;

    Abstract : The wind speed variability and wind power potential in the Greater Horn of Africa is analyzed in this study to fill a knowledge gap regarding if wind power can be used more as a source of energy for the region. This is investigated based on reanalysis data from ERA5, observed wind speeds, CORDEX-Africa regional climate models (RCMs) for future projections and a literature review. READ MORE

  3. 2. Modeling the penetration of fragmented shaped charge jets

    University essay from Uppsala universitet/Materialfysik

    Author : Alexander Palfelt; [2023]
    Keywords : Shaped charge; Analytical penetration model; Visualization; Riktad sprängverkan; RSV; Analytisk penetrationsmodell; Visualisering;

    Abstract : The penetration power of a shaped charge is an important characteristic in determining its capability. A model has previously been developed by FOI to analytically predict the penetration of a shaped charge jet striking a target at varying stand-off distances. READ MORE

  4. 3. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

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

    Author : Ahsan Ali; [2023]
    Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  5. 4. 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

  6. 5. Pathway for Sustainable Aviation : Analysis of Science-Based Targets for Aviation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sebastian Lindfors; [2023]
    Keywords : Aviation; Airline; Science-Based Targets initiative; Climate change; Sustainable transformation; Alternative fuels; Sustainable aviation fuels SAF ; Hydrogen; Electric aviation; Scenario analysis; Flygindustrin; Flygbolag; Science-Based Targets-initiativet; Klimatförändring; Hållbar transformation; Alternativa bränslen; Hållbart flygbränsle; Väte; Elektrisk flygning; Scenarioanalys 437 07-21;

    Abstract : In order for the aviation industry to meet the targets of the Paris agreement and reach net-zero by 2050, significant amounts of greenhouse-gas emissions are to be reduced. However, as the industry is essentially dependent on conventional jet fuel, it becomes necessary for alternative technologies to develop and phase out fossil-based fuels. READ MORE
