  1. 1. Material Characterization by Millimeter-Wave Techniques

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

    Author : Leonard Andersson; [2016]
    Keywords : time domain; Material Characterization; frequency domain; reflection; transmission; free space; permittivity; conductivity; PMMA; Silicon; Measurement; Technology and Engineering;

    Abstract : This master thesis investigates material characterization by reflection and transmission of electromagnetic waves in the 40-60 GHz band (millimeter-wave spectrum) for different materials. The free-space measurement method is a fast, efficient and non-destructive way of examining a material and is being researched by both academics and industries. READ MORE

  2. 2. Developments of detection of X-ray scattering in combustion - characterization of noise levels of an A/D sampling device

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

    Author : Björn Annby Andersson; [2016]
    Keywords : noise; detector resolution; detection; X-ray scattering; Combustion physics; Physics and Astronomy;

    Abstract : A simple investigation about the noise of the acquisition cards NI PXI-4495, provided by National Instruments, was performed. Standard deviations were calculated for data acquired from a signal generator, a constant voltage source and when the input channels were grounded, to estimate the noise. READ MORE

  3. 3. 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

  4. 4. Parameter Optimization for Equilibrium Solutions of Mass Action Systems

    University essay from Lunds universitet/Matematik LTH och numerisk analys

    Author : Edvard Johansson; David Petersson; [2016]
    Keywords : Strict Quasiconvexity; Parameter Optimization; Strict Quasilinearity Infinity Norm; Max Norm; Technology and Engineering; Mathematics and Statistics;

    Abstract : In this thesis, functions describing relations between chemical concentrations at equilibrium are studied. The functions have some parameters that are desired to be determined. Based on the properties of the functions, an optimization method will be proposed. READ MORE

  5. 5. 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 : Tunable laser; GASMAS; 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.
