  1. 1. How is returns management differentiated between click-and-mortar and pure play companies?

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Emma Midgley; Victoria Seim Strömseng; [2019-06-20]
    Nyckelord :;

    Sammanfattning : The emergence of e-commerce and returns management has not only provided a wide selection of corporate opportunities, but it has also come with new obstacles that challenge competitive objectives, goals and strategies of businesses. The following thesis aims to distinguish returns management processes between click-and-mortar and pure player companies. LÄS MER

  2. 2. Wireless electrocardiogram based on ultra-wideband communications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Maria Toll; [2019]
    Nyckelord :UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

    Sammanfattning : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).

  3. 3. Production of the Σ0-bar hyperon in the PANDA experiment at FAIR

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Gabriela Pérez Andrade; [2019]
    Nyckelord :PANDA; hadrons; hyperons;

    Sammanfattning : The PANDA experiment is one of the main pillars of the Facility for Antiproton and Ion Research (FAIR), currently under construction in Darmstadt, Germany. PANDA will be a fixed target experiment designed for the study of non-perturbative phenomena of the strong interaction. LÄS MER

  4. 4. Single Channel Spectrum-based Speech Enhancement Using Neural Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Filip Wen-Fwu Tsai; [2019]
    Nyckelord :;

    Sammanfattning : The ability to communicate is fundamental to form a relationship, and it is anecessity for a well-functioning society. Since a major part of our daily communicationtakes place orally, the ability to perceive speech is important. LÄS MER

  5. 5. Deep-Learning Side-Channel Attacks on AES

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Martin Brisfors; Sebastian Forsmark; [2019]
    Nyckelord :AES; Machine Learning; Side Channel Attack; Encryption; AES; maskinlarning; sidokanalattack; kryptering;

    Sammanfattning : Nyligen har stora framsteg gjorts i att tillämpa djupinlärning på sidokanalat- tacker. Detta medför ett hot mot säkerheten för implementationer av kryp- tografiska algoritmer. Konceptuellt är tanken att övervaka ett chip medan det kör kryptering för informationsläckage av ett visst slag, t.ex. LÄS MER
