  1. 21. Non-fungible tokens: tracing shifts in the art market

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för företagande och ledning

    Författare :Julius Woeste; [2022]
    Nyckelord :NFT; art market; actor-network theory; Bourdieu; cartography of controversies;

    Sammanfattning : Given the advent and market boom of NFTs, this thesis concerns itself with observing how NFTs are shifting the art market, and how those shifts can be explained, as the two seemingly disparate markets have different actors, processes and characteristics. In order to answer these questions the thesis takes an abductive case study design and employs an actor-network theory (ANT) approach to observe shifts in the markets by both human and non-human actors.

  2. 22. Pneumatic Underground Waste Management System : A Technological Innovation System Analysis

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Shashank Jagadeesha; Darshan Venkatesh; [2022]
    Nyckelord :;

    Sammanfattning : Most of the urban areas face solid waste management issues due to the constantly rising population. The functional component of trash collection comprises not only the collection of solid waste and recyclables but also the transportation of the waste in vehicles to recycling/dumping centers.

  3. 23. Approximating Quasistationary Distributions Using Deep Learning

    Master-uppsats, KTH/Matematisk statistik

    Författare :Björn Wehlin; [2022]
    Nyckelord :Applied Mathematics; Deep Learning; Probability Theory; Stochastic Processes; Ito Diffusions; Quasistationary Distributions; Tillämpad matematik; djupinlärning; sannolikhetsteori; stokastiska processer; Ito-diffusioner; kvasistationära fördelningar;

    Sammanfattning : We study a class of It\={o} diffusion processes on domains with smooth boundary, at which the process is killed. Such a process, when conditioned on non-extinction, gives rise to a stationary state known as a \emph{quasistationary distribution} (QSD). LÄS MER

  4. 24. Physics-Based Modelling for SEI and Lithium Plating During Calendar and Cycling Ageing

    Master-uppsats, KTH/Kemiteknik

    Författare :Oskar Nordlander; [2022]
    Nyckelord :Lithium-ion Battery; Calendar Ageing; Cycling Ageing; Battery Degradation; Physics-Based Modelling; SEI; Lithium Plating; Litium-jonbatterier; Kalenderåldring; Cykling åldrande; Batteriåldrande; Fysikbaserad Modellering; SEI; Litium Plätering;

    Sammanfattning : Målet med projektet var att undersöka samt implementera en fysikbaserad DFN modell för att simulera kalender samt cyklingåldrande av litiumbatterier som används i elbilar. Den fysikbaserade modellen var konstruerad baserad på ett Python biblioteket vid namn PyBaMM, vilket till skillnad från datadrivna modeller ger essentiell information om de kemiska processerna inuti batteriet.

  5. 25. The Diffusion of Hydrogen Technology in the Road Transport Sector in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Henrik Bratt; [2022]
    Nyckelord :Alternative fuels; Diffusion of Innovations; Fuel Cell Electric Vehicles; Hydrogen diffusion; Hydrogen-powered vehicle; Sustainable Development;

    Sammanfattning : Carbon emissions are one of the primary drivers of climate change and the transport sector accounts for 24% of the global carbon emissions. A shift within the automobile industry towards more eco-friendly modes of transportation is hence needed. LÄS MER
