  1. 16. Interaction of sublevels in gated biased semiconductor nanowires

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Henrik Karlsson; [2016]
    Keywords : nanowire; spintronics; lateral spin-orbit coupling; asymmetrical confinement potential; spin polarization;

    Abstract : Mesoscopic devices, such as nano-wires, are of interest for the next step in creating spintronic devices. With the ability to manipulate electrons and their spin, spintronic devices may be realised. To that end the different effects found in low-dimensional devices must be studied and understood.

  3. 17. STRUCTURAL ANALYSIS OF TRUSS CONSTRUCTION FOR WIND TURBINE BLADES

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Björn Weddig; [2016]
    Keywords : Wind turbine blade; FRP; Truss system; Instability; Buckling; Non-Linear; Eigenvalue problem; Frequency response analysis; Transient dynamic response; Technology and Engineering;

    Abstract : The usage of wind turbines during the latest years has grown substantially and are becoming an increasingly important source of renewable energy, as many countries are trying to reduce their reliance on fossil fuels. In order to increase the effect of the wind turbines the length of the blades has been increased, which has also led to an increase of the cross-section dimensions. READ MORE

  4. 18. Models and algorithms for the study of traffic with delay

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Hanna Fredenklo Jansson; Ruth Aleksandrauskaite; [2016]
    Keywords : ;

    Abstract : Trac is an essential matter to examine and understand since it is a paramount aspect of modern society. The objective in this bachelor thesis is to formulate models that describe the propagation of vehicles and analyse these using the concepts of stability as well as sensitivity. READ MORE

  5. 19. Fingerprint Matching - Hard Cases

    University essay from Lunds universitet/Matematik LTH

    Author : Alexander Karlsson; Johan Hagel; [2016]
    Keywords : Interest point; descriptor; matching; gray scale matcher; false reject rate.; Mathematics and Statistics;

    Abstract : Today fingerprint matching software is widely used in applications such as mobile phones. Software for enrollment and verification of fingerprints is usually designed to work for "good" fingerprints, meaning that the fingerprint matching algorithms use minutiae locations. READ MORE

  6. 20. On Identification of Hidden Markov Models Using Spectral and Non-Negative Matrix Factorization Methods

    University essay from KTH/Reglerteknik

    Author : Robert Mattila; [2015]
    Keywords : ;

    Abstract : Hidden Markov Models (HMMs) are popular tools for modeling discrete time series. Since the parameters of these models can be hard to derive analytically or directly measure, various algorithms are available for estimating these from observed data. READ MORE
