  1. 1. Tau phosphorylation on threonine 217 as a potential biomarker for neurodegenerative diseases

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

    Author : Sukri Omar Jama; [2019]
    Keywords : P217; hyperphosphorylation; Taupathies; CSF; plasma; serum; Simoa; antibodies; assay; Progressive supranuclear palsy; Alzheimer’s disease and Global glial Taupathies; P217; hyperfosforyrlering; Taupathies; CSF; plasma; serum; Simoa; antikroppar; analys; Progressiv supranukleär pares; Corticobasal degeneration och Globular glialtauopati;

    Abstract : Hyperfosforylering av biomarkörproteinet Tau förekommer i flera neurodegenerativa sjukdomar som kallas Taupathies. Proteinets huvudfunktion i människokroppen är att modulera flexibilitet och stabilitet för axonal-mikrotubulin. I Taupathies utlöser hyperfosforyleringen av Tau instabilitet och neurodegenerationen.

  2. 2. Numerical analysis of aerodynamic damping in a transonic compressor

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

    Author : Vincenzo Stasolla; [2019]
    Keywords : transonic compressor; flutter; vibration; CFD; transonic kompressor; fladder; vibration; CFD;

    Abstract : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.

  3. 3. Opportunities, Barriers and Preconditions for Battery Energy Storage in Sweden : A Study Investigating the Possibilities of Grid Connected Lithium-Ion Battery Energy Storage Systems in the Swedish Electricity Market

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

    Author : Maja Isaksson; Ellen Stjerngren; [2019]
    Keywords : Energy storage; Battery energy storage system; Lithium-ion batteries; Stationary applications; Grid flexibility; Electricity market; Regulatory framework;

    Abstract : The global energy system is under transformation. The energy transition from a centralized, fossil fuel based energy system to a more decentralized, renewable energy based system will challenge the balancing of electricity supply and demand. This stresses the importance of grid flexibility. READ MORE

  4. 4. Pac-King : Placement of IR Sensors on Line Following Robot and Construction of a Gripper and Lift

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

    Author : Tess Antonsson; Sofia Jönsson; [2019]
    Keywords : Mechatronics; Line Following Robot; Infrared sensor; Gripper; Lift; Robotics; Mekatronik; Linjeföljarrobot; Infraröd sensor; Grepp; Lift; Robotik;

    Abstract : Line following robots are a practical mechatronics solution in a world that is becoming more and more automated. With added gripping and lifting abilities, a very versatile robot can be created. The goal of this thesis was to create a prototype that could navigate a black line using infrared sensors whilst gripping and lifting a package. READ MORE

  5. 5. Powertrain of heavy electric vehicles: : Analysis of the production chain and impact on environment and industry

    University essay from KTH/Energiteknik

    Author : Svenja Gelpke; [2018]
    Keywords : ;

    Abstract : Elektrifiering av bilar och mindre transportfordon pågår och flottaaktier ökar men diskussionen om elektrifiering av långdistanstransport är relativt ny. Elektriska lastbilar som använder fossila bränslen och som produceras med förnybara energikällor är lovande, särskilt i länder med en ren elmix. READ MORE
