  1. 1. Temperature distribution in air tight cavities of steel framed modular buildings when exposed to fire

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser; Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Elin Bergroth; Greta Torstensson; [2019]
    Keywords : Cavities; fire furnace; fire test; modular building; steel; TASEF; Brandugn; brandtest; hålrum; modulbyggnader; stål; TASEF;

    Abstract : A common way to construct large buildings is by assemble prefabricated modules around a load bearing steel construction. However, if a fire occurs these buildings can be subject to a rapid fire spread due to its cellular nature. READ MORE

  2. 2. Instance-level Object Detection of Grocery Store items using R-CNN:s

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Rydén; [2019]
    Keywords : Image analysis; simulation; r-cnn; Mathematics and Statistics;

    Abstract : Currently, the best ways to perform object detection in an image is to use a neural network trained on large sets of annotated data. However, in certain environments, the number of objects is large and gathering a sufficiently big set of annotated data is prohibitively expensive. READ MORE

  3. 3. Mechanical properties of SiC nanowires with polytypes

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Anders Vesti; [2019]
    Keywords : atomistic modeling; nanowires; molecular dynamics; simulation; SiC; silicon carbide; fracture behavior; nanomechanics; Physics and Astronomy;

    Abstract : In this report, we model the mechanical properties and fracture behavior of SiC nanowires with different polytypes using Molecular Dynamics (MD) simulations. The mechanical properties investigated are the Young’s modulus, the maximum tensile stress and the fracture strain. The three polytype tested are SiC (3C), (2H) and (4H). READ MORE

  4. 4. Finite element modelling of strained nanowire heterostructures

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Alexander Grape Wyke; [2019]
    Keywords : Strain; nanowire; heterostructure; physics; nanophysics; COMSOL; simulation; lattice; Physics and Astronomy;

    Abstract : When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. READ MORE

  5. 5. Implementation of an 8-bit Dynamic Fixed-Point Convolutional Neural Network for Human Sign Language Recognition on a Xilinx FPGA Board

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Ricardo Núñez-Prieto; [2019]
    Keywords : Artificial Intelligence; Computer Vision; Machine Learning; Convolutional Neural Networks; FPGA; Sign Language Recognition; Technology and Engineering;

    Abstract : The goal of this thesis work is to implement a convolutional neural network on an FPGA device with the capability of recognising human sign language. The set of gestures that the neural network can identify has been taken from the Swedish sign language, and it consists of the signs used for representing the letters of the Swedish alphabet (a.k.a.
