  1. 21. Classifying stock returns using high-frequency fundamental factors and convolutional neural networks

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Denis Dvinskikh; Axel Kotnik; [2021]
    Keywords : convolutional neural networks; fundamental factors; technical indicators; high-frequency stock prices; classification;

    Abstract : We evaluate the usefulness of high-frequency fundamental factor exposures of five US equities, between 2013 and 2017, as features for classifying and predicting the binary movements of the same stocks in 5-minute and 20-day intervals using Convolutional Neural Networks (CNN). After plotting rolling factor betas (Market, HML, SMB) and the close price of a given stock in the corresponding intervals, these time series are converted into images as Gramian Angular Difference Fields (GADF) and then concatenated to be fed to the CNN as input.

  3. 22. Analysis of the Potential of Different Foam Materials in Face Protection to Reduce the Risk of Concussions in Ice Hockey

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Annika Neumann; [2021]
    Keywords : Ice Hockey Jaw Protection; FEM; Concussion; Foam;

    Abstract :  Ice hockey players are at a high risk to sustain a concussion. Most of the concussion-inducing hits are to the jaw region, nevertheless, most players do not wear any protective gear shielding the jaw. READ MORE

  4. 23. FORESAIL-2 AOCS Trade Studies and Design

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Guillaume Le Bonhomme; [2020]
    Keywords : space engineering; CubeSat; ADCS; AOCS; spacecraft subystems; nanosatellite;

    Abstract : This thesis aims to design a reliable CubeSat platform, including the avionic subsystems that can sustain a high radiation environment for a mission having a lifetime of at least six months. The science instruments put stringent requirements on the platform to achieve and maintain the desired spin rate. READ MORE

  5. 24. Experimental studies at CERN-nTOF of the 230Th(n,f) reaction

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Felicia Lapinski; [2020]
    Keywords : fission; neutron induced fission; fission cross section; fission fragment angular distribution; thorium;

    Abstract : This work investigates the feasibility to perform an experiment at CERN n_TOF to study the fission cross section and fission fragment angular distribution (FFAD) of the 230Th(n,f) reaction. An analysis of fission fragment energy losses in the experimental target resulted in a choice of target thickness of 0. READ MORE

  6. 25. Investigating RT using two-particle angular correlations in proton-proton collisions

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Dilan Chroscik; [2020]
    Keywords : particle physics; proton-proton collisions; two-particle angular correlations; underlying event; relative transverse activity; ALICE; LHC; collective flow; long range correlations; Physics and Astronomy;

    Abstract : The observable, RT , is investigated using two-dimensional (∆η, ∆φ) angular correlations, where ∆η and ∆φ are the differences in pseudorapidity and azimuthal angle respectively, between the trigger and associated tracks. The analysed data consists of reconstructed tracks, from proton-proton collisions at collision energy ps = 13 TeV, taken from the ALICE detector at the LHC. READ MORE
