  1. 11. Homebuilt reactor design and atomic layer deposition of metal oxide thin films

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Pamburayi Mpofu; [2021]
    Nyckelord :Thin films; atomic layer deposition;

    Sammanfattning : This research thesis covers work done on building an atomic layer deposition (ALD) reactor followed by the development and optimization of an ALD process for indium oxide thin films on crystalline silicon substrates from new precursors using this new homebuilt cost-effective tool. This work describes the design, building and testing of the ALD system using an indium triazenide precursor and water in a novel precursor combination. LÄS MER

  3. 12. Deep Learning Approach for Extracting Heart Rate Variability from a Photoplethysmographic Signal

    M1-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Gudny Björk Odinsdottir; Jesper Larsson; [2020]
    Nyckelord :Heart rate variability; photoplethysmograpic signal; human activity recognition; deep learning approach; recurrent neural network; long short-term memory network;

    Sammanfattning : Photoplethysmography (PPG) is a method to detect blood volume changes in every heartbeat. The peaks in the PPG signal corresponds to the electrical impulses sent by the heart. The duration between each heartbeat varies, and these variances are better known as heart rate variability (HRV). LÄS MER

  4. 13. Corrosion studies on multicomponent TiZrNbTa thin films

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Asker Jarlöv; [2020]
    Nyckelord :Corrosion resistance; Multicomponent thin-film; High entropy alloy; TiZrNbTa; Bipolar plates; Magnetron sputtering;

    Sammanfattning : The goal of this work was to evaluate the electrochemical properties of TiZrNbTa thin films deposited by magnetron sputtering using an industrial physical vapor deposition system. Samples were deposited on both Si(001) and 316L stainless steel. LÄS MER

  5. 14. Process and microstructure development of a LPBF produced maraging steel

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Kenny Johansson; [2020]
    Nyckelord :Maraging steels; additive manufacturing; Laser Powder Bed Fusion; LPBF; additiv tillverkning; maråldringsstål; pulverbädd;

    Sammanfattning : Additive manufacturing (AM) has the possibility of producing complex-shaped components which can not be produced by conventional manufacturing methods. This gives the opportunity for designers to freely think outside the design spectra which is otherwise limited by conventional manufacturing methods. LÄS MER

  7. 15. Artificial Intelligence for detecting IoT data intrusions

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Daniel Nilsson; [2020]
    Nyckelord :;

    Sammanfattning : The importance of the Internet of Things (IoT) continues to grow in modern society,yet it remains relatively vulnerable to data intrusion attacks. These attacks can compromise both the IoT networks them selves and the services that rely on them. LÄS MER
