  1. 21. Graphical lasso for covariance structure learning in the high dimensional setting

    University essay from KTH/Matematisk statistik

    Author : Viktor Fransson; [2015]
    Keywords : ;

    Abstract : This thesis considers the estimation of undirected Gaussian graphical models especially in the high dimensional setting where the true observations are assumed to be non-Gaussian distributed. The first aim is to present and compare the performances of existing Gaussian graphical model estimation methods. READ MORE

  3. 22. Parallelisation and Performance Analysis of a TreeSPH Code for Galaxy Simulations

    University essay from KTH/Numerisk analys, NA

    Author : Maximilian Volkan Baloglu; [2014]
    Keywords : ;

    Abstract : In cosmological simulations, the Lagrangian method Smoothed Particle Hydrodynamics is often applied to cover gas dynamics and combined with tree algorithms for long-range potentials like the Barnes-Hut method to include self-gravity and derive the nearest neighbour lists efficiently. In this thesis, a so-called TreeSPH code is parallelized by using MPI and subsequently the performance is analysed. READ MORE

  4. 23. ””Världens bästa planeringsprocess” - en analys av en informationsflödesprocess hos ett flygbolag på den skandinaviska marknaden

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Maria Modin; [2014]
    Keywords : Flygbolag; planering; förfrågning; process; flödeskartläggning; effektivisering; tidsreducering; logistik; Lean production; informationsflödesprocess; Alternate Chief Pilot; synkronisering; parallellisering; sekvensering;

    Abstract : Detta projekt har utförts på ett charterflygbolag som verkar på den skandinaviska flygmarknaden, och är en första del i flygbolagets projekt (översatt till svenska) ”Världens bästa planeringsprocess”. ”Världens bästa planeringsprocess” skall kartlägga flygbolagets planeringsprocess sett till från det att en förfrågan kommer in till flygbolaget, till dess att ett svar kan lämnas till kunden.

  5. 24. Large-scale time parallelization for molecular dynamics problems

    University essay from KTH/Numerisk analys, NA

    Author : Johannes Bulin; [2013]
    Keywords : ;

    Abstract : As modern supercomputers draw their power from the sheer number of cores, an efficient parallelization of programs is crucial for achieving good performance. When one tries to solve differential equations in parallel this is usually done by parallelizing the computation of one single time step. READ MORE

  6. 25. A Survey & Implementation of Financial Alarm Classification.

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Jens Wirén; Farhad Kimanos; [2013]
    Keywords : ;

    Abstract : The goal of this thesis is to find, implement and evaluate a suitable machine learning algorithm to classify and predict true and false alerts using labelled data. Alerts are triggered in the Scila Surveillance software when certain parameters are exceeded in a trade, such as a to big volume over a to small time-span. READ MORE
