    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : David Sundvall; [2022]
    Keywords : human centered design; frugal innovation; Innovation; resource constrained environment; Bottom of the pyramid; BOP; Jugaad; resource constrained environment design; Mänskligt centrerad design; Sparsam innovation; Innovation; Resursbegränsad miljö; Botten av den socioekonomiska pyramiden; BOP; Jugaad; Resursbegränsad miljö design;

    Abstract : Patrick and Felicia are a couple who run a farm. Every day they harvest their crops and sell them at the local market. This is the family's everyday life and today's income goes to all the family'sexpenses such as food, water, and transport to the market. At the end of the day, the family's totalbudget results in plus or minus zero. READ MORE

  3. 2. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Hanna Sjö; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.

  4. 3. Quantum thermodynamics explorations with a Hubbard-Holstein dimer

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Emil Adam Jonatan Östberg; [2021]
    Keywords : QTD Quantum Thermodynamics Hubbard-Holstein Hubbard Holstein dimer Lanczos Suzuki-Trotter ST Exact diagonalization ED Hysteresis Path dependence Battery Mott-insulator; Physics and Astronomy;

    Abstract : The goal of this project is to characterize the quantum thermodynamics of a Hubbard-Holstein dimer. We explore how the standard formalism of quantum thermodynamics behaves in the context many-body physics. READ MORE

  5. 4. Constrained Gaussian Process Regression Applied to the Swaption Cube

    University essay from KTH/Matematik (Avd.)

    Author : Adrien Deleplace; [2021]
    Keywords : Swaption cube; Constrained Gaussian process regression; No arbitrage; Option pricing; Hamiltonian Monte Carlo; Swaption-kuben; Regression för gaussiska processer med bivillkor;

    Abstract : This document is a Master Thesis report in financial mathematics for KTH. This Master thesis is the product of an internship conducted at Nexialog Consulting, in Paris. This document is about the innovative use of Constrained Gaussian process regression in order to build an arbitrage free swaption cube. READ MORE

  6. 5. PID Regulated Balancing Cube

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

    Author : SEBASTIAN BRANDMAIER; DENIS RAMSDEN; [2020]
    Keywords : Mechatronics; PID-control; Reaction wheel; Arduino; Cube.; Mekatronik; PID-kontroll; Reaktionshjul; Arduino; Kub.;

    Abstract : In this project a cube was constructed with the intent for it to balance on one of its edges by regulating the speed of a reaction wheel. To be able to do this, a research was done to understand the mechanics of the system and to know what components were required for the project. READ MORE
