  1. 1. ”Att ensamt slåss motväderkvarnarna är definitivt inte lika kul som tillsammans mot krisen.” : Drivkrafter som påverkar klimataktivistiska studenters syn på densocioekologiska transformationen

    Kandidat-uppsats, Karlstads universitet/Institutionen för samhälls- och kulturvetenskap (from 2013)

    Författare :Kerstin Anton; [2023]
    Nyckelord :vision; self-experience opportunities; adaptation; climate-activism; vision; självutveckling; anpassning; klimataktivism;

    Sammanfattning : Unga klimataktivisters drivkrafter beskrivs ofta i negativ konnoterade termer som klimatångest eller flygskam i media och deras livsstilar sägs vara full av begränsningar. Denna studie undersöker hur klimataktivistiska studenter själva ser på sin livsstil och vilka visioner de har för en socioekologisk transformation. LÄS MER

  3. 2. Fano Resonances in Time-Dependent Wells

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Anton Gregefalk; [2023]
    Nyckelord :Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

    Sammanfattning : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. LÄS MER

  4. 3. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  5. 4. Automatic Recycling Sorting Unit: A platform designed to sort glass, plastic and metal

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Anni Li; Agnes Agåker Karlsson; [2023]
    Nyckelord :Mechatronics; Recycling; Inductive sensor; Capacitive sensor; Loadcell; Mekatronik; Återvinning; Induktivsensor; Kapacitivsensor; Viktcell;

    Sammanfattning : This report describes the design and construction of a tilting platform for sorting household waste, limited to plastic, glass, and metal. The platform utilizes a capacitive sensor to identify if an object is placed on the platform, an inductive sensor to detect metal, and a load cell to differentiate between plastic and glass based on their weight difference.

  7. 5. Dynamics of a CRAFT : A simulation study on a Counter Rotating vertical Axis Floating Tilting wind turbine

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Benjamin Hedlund Peters; Linda Goude; [2023]
    Nyckelord :wind power; counter rotating; contra rotating; offshore wind; floating wind power; vertical axis wind turbine; VAWT; renewable energy;

    Sammanfattning : In this thesis the Counter Rotating vertical Axis Floating Tilting wind turbine (CRAFT) has been explored by creating a simulation model in the program Simulink. The CRAFT prototype is a new type of wind turbine under development by World Wide Wind and Uppsala University with the aim to produce a large scale floating vertical axis wind turbine (VAWT) with two cone shaped counter rotating turbines.
