  1. 1. Statistical Survey of Earth’s Magnetopause Using MMS Data : Pressure Balance, Total Pressure Contributions and Magnetopause Velocity near the Subsolar Point, Dawn- and Dusk Flanks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Arthur Grönlund; [2021]
    Keywords : Magnetopause; Magnetosheath; Magnetosphere; Pressure balance; Total pressure contributions; Magnetopause velocity;

    Abstract : The magnetopause is an important feature in near-Earth space, where the continuously emitted solar wind from the sun meets the magnetic field of the Earth. This boundary region between the so-called magnetosheath on the outside and magnetosphere on the inside is a constantly back-and-forth moving discontinuity upheld by a pressure balance on both sides, upon which an important process in mass and energy transportation through the universe called magnetic reconnection occurs.

    Abstract : This thesis provides a standardized method to measure accuracy for engine and gearbox sensors. Accuracy is defined by ISO 5725, which states that trueness and precision need to be known to provide a metric for accuracy. However, obtaining and processing the data required for this is not straight forward. READ MORE

  4. 3. Design and layout of power conversion chain for a wave energy converter

    University essay from KTH/Elkraftteknik

    Abstract : Wave energy has the potential to provide an energy resource in this challenging energyenvironment. Wave energy converters are devices used to extract this energy and convertit into electricity. READ MORE

  5. 4. Ammonia Metal Halides Thermochemical Heat Storage System Design

    University essay from KTH/Energiteknik

    Author : Michail Laios; [2017]
    Keywords : thermochemical heat storage TCS ; NH3-SrCl2 system; absorption; desorption; numerical modelling; Aspen; termokemisk värmelagring TCS ; NH3-SrCl2 system; absorption; desorption; numerisk modellering; Aspen;

    Abstract : One of the most crucial issues nowadays is the protection of the environment and the replacement of fossil fuels, which are abundantly used around the world, with more efficient and renewable sources. The highest portion of global energy demands today is used in heating and cooling purposes. READ MORE

  6. 5. Spin-FET based on InGaAs/InP heterostructure

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

    Author : Ricardo Moreira Salles De Andrade; [2011]
    Keywords : Spin; Spintronics; Field-effect transistor; Datta-Das transistor; Rashba effect; Low-temperature.; Physics and Astronomy;

    Abstract : A new design based on the spinFET proposed by Datta-Das was fabricated, using a channel defined by etching on a 2DEG material and nanomagnets as top-gates. The magnetotransports properties were measured at low temperatures. READ MORE
