  1. 21. Improvement of conductivity measurement in liquid chromatography

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Jerker Ortman; [2021]
    Keywords : conductivity; liquid chromatography; electronics; sensors; measurement techniques;

    Abstract : In liquid chromatography the ability to measure the conductivity is essential toreach a good result. This is done by applying a current through the electrolyte ofinterest and measuring the voltage drop over the electrolyte. The conductivity isthen calculated with the known current and the measured voltage. READ MORE

  3. 22. Detection of in-plane orbital manoeuvres from a catalogue of geostationary objects

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Phuong Linh Ngo; [2020]
    Keywords : manoeuvre detection; geostationary orbit; perturbations; filters; Two-line elements; station keeping;

    Abstract : The number of man-made space objects is dramatically growing nowadays. The continuous monitoring and studying of these objects are necessary to keep their number under control and ensure safe space operations. READ MORE

  4. 23. Analysis and Implementation of a Method to Smooth Data Functions

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Sarah Rohart; [2020]
    Keywords : Spline; Numerical Analysis; Mathematics; Data; Smoothing; Computer; Mathematics and Statistics;

    Abstract : The goal of the thesis is to create a method that can be used to smooth data functions so that they are more easily readable and interpretable, through curve fitting. So as to do that, we adapt the smoothing spline method, which uses discrete data, to continuous data... READ MORE

  5. 24. Development and Assessment of Re-Fleet Assignment Model under Environmental Considerations

    University essay from KTH/Optimeringslära och systemteori

    Author : Prashant Prashant; [2020]
    Keywords : Aviation; Fleet Assignment; Greenhouse Gases; Linear Optimization; Resource Management; Applied Mathematics; Mathematical Modelling; Flygindustrin; Tillämpad Matematik; Linjär Optimering; Fleet Assignment; matematisk modellering;

    Abstract : The imminent threat of global catastrophe due to climate change gets more real by each passing year. The Aviation trade association, IATA, claims that Aviation accounts for approximately 2% of the Greenhouse Gases (GHG) caused by human activities, and 3.5% of the total Radiative Forcing. READ MORE

  6. 25. The spatial distribution of dark matter in the Universe

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Tamina Lund; [2020]
    Keywords : dark matter halos; NFW profile; curve fitting; Bayesian inference; least Squares; data uncertainties; Physics and Astronomy;

    Abstract : It was previously found that the density profile of dark matter halos is well-fit by a universal, smooth function over a vast range of masses and redshifts, named the Navarro-Frenk-White (NFW) profile after its discoverers. Despite its impressive goodness of fit, the NFW model remains an approximation of the density profile of realistic halos. READ MORE
