  1. 1. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

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

    Author : Jacob Lindahl; [2023]
    Keywords : LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

    Abstract : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. READ MORE

  2. 2. Exploring Near-Field SAR with mmWave Pulsed Coherent Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Elina Yrlid; [2023]
    Keywords : SAR; Synthetic Aperture Radar; PCR; pulsed coherent radar; radar; mmWave; millimeter-wave; near-field; 60GHz; Technology and Engineering;

    Abstract : This thesis explores the option to apply Synthetic Aperture Radar (SAR) techniques to image near-field targets utilizing mmWave pulsed coherent radar (PCR). The recent development of mmWave radars has broadened the scope for SAR, but there are few concrete examples explaining and demonstrating the fundamental SAR algorithms from a PCR perspective.

  3. 3. Wood and moisture-induced strains in a large deformation setting in 3D

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Fredrik Ström; Anwar Obeido; [2022]
    Keywords : Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

    Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

  4. 4. An aeroelastic prediction model for slender wings in supersonic flow

    University essay from KTH/Flygdynamik

    Author : Zakarias Priebe; Alexander Hasp Frank; [2021]
    Keywords : ;

    Abstract : Aeroelasticity is a multidisciplinary subject encompassing several fields of study. Aeroelastic behaviour is defined by the relation between inertial-, elastic- and aerodynamic forces that appear in dynamic systems in steady- or unsteady conditions. READ MORE

  5. 5. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Emil Nilsson; [2021]
    Keywords : CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

    Abstract : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.
