  1. 1. Oscillations in a complex sunspot: From theory to data

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Femke Kranenbarg; [2024]
    Keywords : ;

    Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  3. 2. The Role of Transport Purchasing Companies in the Reduction of Freight Transport Emissions : The Opportunities and Barriers of Environmentally Friendly Freight Transport

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

    Author : Alva Lundgren; Ellen Haavikko; [2023]
    Keywords : Freight transport; green logistics; environmentally friendly logistics; sustainable freight transport; voluntary environmental targets; corporate carbon strategies; transport purchasing companies; PESTEL-analysis; Godstransporter; grön logistik; miljövänlig logistik; hållbara godstransporter; frivilliga miljömål; företags koldioxidstrategier; transportinköpande företag; PESTEL-analys;

    Abstract : The freight transport industry accounts for a large and, moreover, an increasing share of the global greenhouse gas emissions. Despite this, previous studies point to the fact that freight transport purchasing companies (TPCs) do not take sufficient action to reduce emissions from the freight transports they buy. READ MORE

  4. 3. Quantum Transport in Topological Insulator Nanowires

    University essay from KTH/Fysik

    Author : Sergi Pradas Rodriguez; [2023]
    Keywords : quantum transport; topological insulators; nanowires; numerical analysis; Kwant; etc.; kvanttransport; topologiska isolatorer; nanotrådar; numerisk analys; Kvant; etc.;

    Abstract : Three-dimensional topological insulators are materials that have a bulk band gap like a traditional insulator, but which hold topologically protected conducting surface states. In this thesis we present a numerical analysis of the surface states of topological insulator nanowires in the tight-binding approximation. READ MORE

  5. 4. Simulations of current transport phenomena in ferroelectric tunnel junctions

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Ivan Lubar; [2022]
    Keywords : Technology and Engineering;

    Abstract : Ferroelectric memories pose as a potential candidate as resistive memory devices that could be used for in-memory computing and artificial synapses. One promising type of ferroelectric memory device is the ferroelectric tunnel junction (FTJ). READ MORE

  6. 5. Parametrization of a Lithium-ion battery

    University essay from KTH/Kemiteknik

    Author : Elsa Arksand; [2021]
    Keywords : Parametrization; LiFePO4; Single particle model; Li-ion battery; Pseudo-OCV; Parametrisering; LiFePO4; Singlepartikelmodell; Litiumjonbatteri; Pseudo-OCV;

    Abstract : Batterimodeller används för att representera batterier. För ändamål som batterihanteringssystem används idag främst empiriska modeller som representerar ett batteri med en motsvarande kretsmodell. Några nackdelar för dessa modeller ligger i dess oförmåga att simulera interna tillstånd och en tidskrävande parametriseringsprocess. READ MORE
