  1. 1. Distributed machine learning for embedded devices

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Niclas Gyllsdorff; [2018]
    Nyckelord :;

    Sammanfattning : The goal of the master thesis is to investigate the feasibility ofhaving distributed machine learning on embedded devices and toanalyse how the architecture of such a system can look like. A systemis proposed which enables machine learning running on multipleembedded devices to communicate with an end application. LÄS MER

  2. 2. Assessing blockchain technology for Transport Data Logger

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Björn Johansson; [2018]
    Nyckelord :blockchain; transport data logger; hyperledger; hyperledger fabric; byzantine fault tolerance; bft; supply chain; transport chain; permissioned; permissionless; documental truth; historical truth; immutability; security; log data; Technology and Engineering;

    Sammanfattning : A proof of concept permissioned blockchain system that holds data from the Transport Data Logger, TDL, was developed. Transport chain actors who hand off TDL-equipped goods between one another use the TDL app to upload a digital handoff containing their identities and log data from and signed by the TDL to a Hyperledger Fabric blockchain network.

  3. 3. Noggrannheten hos ett positioneringssystem baserat på Bluetooth 5 : En jämförande studie av fem olika filtreringsalgoritmers påverkan på positioneringsnoggrannheten

    Kandidat-uppsats, Högskolan i Jönköping/JTH, Datateknik och informatik; Högskolan i Jönköping/JTH, Datateknik och informatik

    Författare :Viktor Karlsson; Eric Pehrsson; [2018]
    Nyckelord :;

    Sammanfattning : Purpose – The purpose of this thesis was to identify and evaluate different filtering algorithms for raw Received Signal Strength Indication (RSSI) values in an indoor positioning system. The purpose was also to examine how the positioning accuracy is affected depending on which filter that was applied to an indoor positioning system based on Bluetooth Low Energy (BLE) 5. LÄS MER

  4. 4. Development of a Bluetooth controller for mobile VR headsets

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

    Författare :Tommy Holmberg; [2018]
    Nyckelord :bluetooth; virtual reality; VR; controller; fiducial markers; aruco; whycon; IMU; accelerometer; BLE; bluetooth low energy;

    Sammanfattning : Mobile virtual reality (VR) headsets have been becoming more and more popular. However, the cheapest headsets do not come with any controllers and the ones that do include controllers only uses sensors for rotation, not translational movement. LÄS MER

  5. 5. Construction, testing and verification of a brushless excitation system with wireless control of the field current in a synchronous generator.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära

    Författare :Rickard Larsson; Kenny Andersson; [2018]
    Nyckelord :Brushless excitation; synchronous generator; bluetooth; torque ripple; Borstlös matning; synkrongenerator; blåtand; momentpulsationer;

    Sammanfattning : Synchronous generators have been used in hydropower from more than a century where, traditionally, the field current is transferred to the rotor using slip rings and carbon brushes. There are some major disadvantages following the use static excitation; regular and expensive maintenance, as well as a source of carbon dust which, due to buildup, may cause short circuits.
