  1. 1. Wireless system design : NB-IoT downlink simulator

    University essay from Uppsala universitet/Signaler och System; Uppsala universitet/Signaler och System

    Author : Piotr Krasowski; Douglas Troha; [2017]
    Keywords : nb-iot; lte; lte-a; downlink; simulator; wireless;

    Abstract : The newly defined NB-IoT standard currently lacks a toolkit and simulator. In order to develop algorithms for this new standard there is a need for channels and signals as reference during tests. MATLAB is commonly used for testing LTE signals and therefore the toolkit was developed in this environment. READ MORE

  2. 2. Evaluation of X-ray Camera As a Tool for Automated Beam Characterization

    University essay from Uppsala universitet/Materialfysik

    Author : Otte Marthin; [2017]
    Keywords : camera; characterization; X-ray; beam;

    Abstract : Several methods for analysing materials and proteins use highly concentrated beams of X-rays, e.g. SAXS and X-ray crystallography. To evaluate the outgoing beam, it is of high importance to know the light distribution of the incoming beam. READ MORE

  3. 3. Diode laser spectroscopy for oxygen detection in the lungs of infants

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Peilang Liao; [2016]
    Keywords : GASMAS; Tunable laser; Transport theory; 3D phantom; Diagnoses; Gas; Lung; Physics and Astronomy;

    Abstract : This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments.

  4. 4. Coupling of neutron optics and shielding using Vitess and Geant4

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Ellen Brydevall; [2016]
    Keywords : Geant4; gamma radiation; neutron; ESS; Vitess; Physics and Astronomy;

    Abstract : The European Spallation Source (ESS) will be a material research center built around a powerful neutron source. At ESS, researchers will be able to carry out precise measurements using neutron scattering. The quality of the measurements is determined by the signal-to-noise ratio. READ MORE

  5. 5. Non-Linear Automatic Control of Autonomous Lawn Mower

    University essay from Linköpings universitet/Reglerteknik

    Author : Hannah Dysenius; [2016]
    Keywords : autonomous lawn mower; non-linear automatic control;

    Abstract : This master thesis contains modeling and nonlinear automatic control of an autonomous lawn mower. The vehicle shall be able to follow a magnetic field loop buried in the lawn on an arbitrary distance, including straddling. A unicycle model of the lawn mower has been derived based on previous work. READ MORE
