  1. 1. On two-component Bose-Einstein condensates in a ring

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Marcus Sköld; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : A Bose-Einstein condensate is a type of gas consisting of one or more types of particles called bosons which are cooled to a temperature very close the absolute zero. Under these conditions the particles all start to occupy their lowest quantum state. READ MORE

  2. 2. Econometric Features of Models Used in Aid Allocation Studies

    University essay from Lunds universitet/Statistiska institutionen

    Author : Sandra Ågren; [2019]
    Keywords : Heckman s two step model Tobit model Multiple linear regression Aid allocation; Mathematics and Statistics;

    Abstract : Research of aid allocation deals with a dependent variable, received aid expressed in absolute or relative terms, that is equal to zero for numerous observations. This is because donor countries tend to target specific countries for their allocation, leaving the rest of the countries without any development assistance. READ MORE

  3. 3. Proposal networks in object detection

    University essay from KTH/Matematisk statistik

    Author : Mikael Grossman; [2019]
    Keywords : Deep learning; Machine learning; Computer vision; Applied mathematics; Statistics; Artificial Neural Networks; Object detection; Faster R-CNN; RPN; Proposal Network; Maskininlärning; Neurala nätverk; Objektdetektering; Tillämpad matematik; Matematisk statistik; RPN; Förslags nätverk;

    Abstract : Locating and extracting useful data from images is a task that has been revolutionized in the last decade as computing power has risen to such a level to use deep neural networks with success. A type of neural network that uses the convolutional operation called convolutional neural network (CNN) is suited for image related tasks. READ MORE

  4. 4. Are GARCH Models Appropriate for Analysing Volatility Structures in Fundamental Valuations of the OMXS30?

    University essay from Lunds universitet/Statistiska institutionen

    Author : Gustav Furenmo; [2019]
    Keywords : GARCH; OMXS30; financial time series; volatility; heteroscedasticity; stationarity; McLeod-Li test; normal distribution; student-t distribution; skewed student-t distribution; generalised error distribution; skewed generalised error distribution; Mathematics and Statistics;

    Abstract : This thesis investigates the volatility structures found in forward-looking fundamental valuations of the Swedish stock index OMXS30. The evaluated data constitutes daily observations of P/E ratios based on twelve months earnings estimates during the period 2009-01-02 until 2018-10-18. READ MORE

  5. 5. Efficient Barrier Option Greeks using Automatic Differentation

    University essay from Lunds universitet/Matematisk statistik

    Author : Gustav Hedin; [2019]
    Keywords : Automatic Differentiation; Greeks; Barrier Option; Vibrato Monte Carlo; Mathematics and Statistics;

    Abstract : Automatic Differentiation (AD) is an effective method for calculation of derivatives. It can evaluate an unlimited number of derivatives to a fixed cost relative to the computing time of the original function. The AD technique is used in many fields for large and complex calculations in order to get accurate values of derivatives fast. READ MORE
