    • Sequential Anomaly Detection for Log Data Using Deep Learning 

      Hammargren, Lina; Wu, Wei (2021-06-14)
      Abstract Software development with continuous integration changes needs frequent testing for assessment. Analyzing the test output manually is time-consuming and automating this process could be beneficial to an ...
    • Simulation and statistical methods for stochastic differental equations 

      Källgren, Christian (2019-12-16)
      We look at numerical methods for simulation of stochastic differential equations exhibiting volatility induced stationarity. This is a property of the process which means that the stationary behaviour is mostly imposed ...

    • Singular and de Rham cohomology for the Grassmannian 

      Anghammar, Oscar (2015-09-16)
      We compute the Poincar e polynomial for the complex Grassmannian using de Rham cohomology. We also construct a CW complex on the Grassmannian using Schubert cells, and then we use these cells to construct a basis for the ...
    • Solving Inverse PDE by the Finite Element Method 

      Amad, Yahya (2012-09-03)
      In this Master thesis project solving inverse PDE by the finite element method. An optimal control problems subjected to PDE constraint with boundary conditions is given. Construct the variational form then construct ...
    • Spatio-temporal analysis of COVID-19 in Västra Götaland, Sweden 

      Andreeva, Natalia (2023-08-23)
      Spatio-temporal analysis of COVID-19 data with the two different statistical approaches is the main objective of this thesis. The first classical approach, the Endemic-Epidemic framework (Held et al., 2005) is a class of ...
    • Statistical Modelling of Pedestrian Flows 

      Håkansson, Erik (2019-06-13)
      Pedestrian counts and in particular their relation to the buildings in the vicinity of the streetandtothestructureofthestreetnetworkisofcentralinterestinthespacesyntax field. This report is concerned with using statistical ...
    • Stochastic Partial Differential Equations with Multiplicative Noise - Numerical simulations of strong and weak approximation errors 

      Petersson, Andreas (2015-06-23)
      A finite element Galerkin spatial discretization together with a backward Euler scheme is implemented to simulate strong error rates of the homogeneous stochastic heat equation with multiplicative trace class noise in ...
    • The New Economy - Knowledge Investments - Enterprises intangible investments - the new source of growth 

      Hashemi, Pasha (2017-03-15)
      Economic-based growth is increasingly becoming dependent on the wide range of intangible investments, known as knowledge-based capital (KBC) investments. Its rapid asset size growth has called for transparency in the ...
    • The noncommutative Shilov boundary 

      Johansson, Jimmy (2016-12-06)
      We introduce Arveson's generalization of the Shilov boundary to the noncommutative case and give a proof based on the work of Hamana of the existence of the Shilov boundary ideal. Moreover, we describe the Shilov boundary ...
    • Three Perspectives of Schiemann’s Theorem 

      Rydell, Felix (2020-06-23)
      Interest in the field of spectral geometry, the study of how analytic and geometric properties of manifolds are related, was sparked when Marc Kac in 1966 asked the question “can one hear the shape of a drum?”. One of ...
    • Volatility Curves of Incomplete Markets 

      Chechelnytska, Kateryna (2020-06-23)
      The graph of the implied volatility of call options as a function of the strike price is called volatility curve. If the options market were perfectly described by the Black-Scholes model, the implied volatility would ...
