  1. 1. Design and Fabrication of a Kinetic Inductance Parameric Amplifier for multi-mode entanglement studies

    University essay from KTH/Tillämpad fysik

    Author : Sara Persia; [2022]
    Keywords : Parametric amplifier; kinetic inductance; superconducting NbTiN nanowires; Parametrisk förstärkare; kinetisk induktans; supraledanden NbTiN- nanotrådar;

    Abstract : Parametric amplifiers are essential for analyzing and measuring the weak signals generated byquantum circuits at cryogenic temperatures. This project aims to realize a low noise travelingwave parametric amplifier (TWPA) by exploiting the nonlinear current dependence of thekinetic inductance of superconducting NbTiN nanowires.

  3. 2. Electrical Impedance Profiling of Plants, Coffee and TREO

    University essay from Uppsala universitet/Signaler och system

    Author : Adam Bushara; Sebastian Daniel Clyne; [2022]
    Keywords : ;

    Abstract :  The aim of the project was to investigate the possibility of using low-cost hardware to monitor plant health, measure the impedance of water containing dissolved substances at different concentrations, and observe how the plant impedance is affected compared to auxiliary measurements of soil moisture, ambient light, humidity, and temperature.To measure impedance, we used electrical impedance spectroscopy which gives the impedanceacross a spectrum of frequencies.

  4. 3. Accuracy verification of GT-Power model and reduction of computational time

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Viktor Dahl; Maja Dyrsmeds; [2022]
    Keywords : Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

    Abstract : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. READ MORE

  5. 4. Development of Characterization methodology for battery research

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Marcus Rydja; [2022]
    Keywords : battery; cell; characterization method; impedance; batteri; cell; karakteriseringsmetod; impedans;

    Abstract : Vår tids miljöutmaning att minska mängden klimatförändringar i framtiden har gjort människor mer miljömedvetna. Högpresterande batterier är nu implementerade i många typer av elektroniska enheter och den ökade efterfrågan driver på utvecklingen av ännu bättre batterier. READ MORE

  6. 5. Developing data processing program for a new radio magnetotelluric (RMT) instrument

    University essay from Uppsala universitet/Geofysik

    Author : Elis Uebel; [2022]
    Keywords : RMT radio magnetotellurics matlab GUI;

    Abstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE
