  1. 1. Boundedness of a Class of Hilbert Operators on Modulation Spaces

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Nils Zandler Andersson; [2019]
    Nyckelord :;

    Sammanfattning : In this work we take interest in frames and modulation spaces. On the basis of their properties, we show how frame expansions can be used to prove the boundedness of a particular class of Hilbert operators on modulation spaces taking advantage of the special category of piece-wise polynomial functions known as B-splines. ..

  2. 2. Deformable 3D Brain MRI Registration with Deep Learning

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Louis Joos; [2019]
    Nyckelord :Deep Learning; Image Registration;

    Sammanfattning : Traditional deformable registration methods have achieved impressive performances but are computationally time-consuming since they have to optimize an objective function for each new pair of images. Very recently some learning-based approaches have been proposed to enable fast registration by learning to estimate the spatial transformation parameters directly from the input images. LÄS MER

  3. 3. Defining and predicting fast-selling clothing options

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Sara Jesperson; [2019]
    Nyckelord :Apparel retail; B-splines; Gaussian mixture model; Probabilistic prediction; Sales prediction;

    Sammanfattning : This thesis aims to find a definition of fast-selling clothing options and to find a way to predict them using only a few weeks of sale data as input. The data used for this project contain daily sales and intake quantity for seasonal options, with sale start 2016-2018, provided by the department store chain Åhléns. LÄS MER

  4. 4. Radiostereometry Using NURBS Implant Models

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Heba Shehabeldin; [2018]
    Nyckelord :;

    Sammanfattning : Radiostereometric analysis (RSA) is a method used for determining migration and wear of orthopaedic implants through measurements performed in radiographs. There are two approaches of RSA: marker-based and model-based (MBRSA). Marker-based RSA is the conventional and most accurate method. LÄS MER

  5. 5. Airfoil Optimization Through Differential Evolution

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Eddie Nilsson; [2017]
    Nyckelord :Differential evolution; optimization; airfoil; wind turbine; Technology and Engineering;

    Sammanfattning : This thesis presents the development of a numerical optimization algorithm for airfoils, and how it can be used in design of wind turbine blades. It was found that the developed algorithm successfully improves the goal parameters under given conditions and constraints. LÄS MER
