  1. 1. Comparative analysis of contact and non-contact method for determining the natural frequencies of a bolted joint

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Malin Dyberg; Elvira Troillet; [2023]
    Nyckelord :;

    Sammanfattning : To ensure high assembly quality of components, a proper clamping force in bolted joints is essential. The existing tightening technology rely on torque and angle; however, this thesis proposes a method for obtaining the clamping force of a bolted joint based on measuring the natural frequencies.

  3. 2. PiChess : Voice Controlled Robotic Chess Player

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Oscar De Brito Lingman; Axel Sernelin; [2021]
    Nyckelord :Mechatronics; Raspberry Pi; Chess; SCARA; Dynamixel; Mekatronik; Raspberry Pi; Schack; SCARA; Dynamixel;

    Sammanfattning : The purpose of this bachelor’s thesis was to create a robot that could play chess through voice recognition and robotics. The two areas to be investigated were the robot’s precision and speed. The reason for building a robot arm of the SCARA type was that it can easily pick up and place pieces with reach over the entire chessboard. LÄS MER

  4. 3. Taluppfattbarhet med strupmikrofon

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

    Författare :Erik Wickman; [2018]
    Nyckelord :throat microphone; frequency response; speech intelligibility; contact microphone; transfer function; accelerometer; communication; signal-to-noise ratio; strupmikrofon; frekvenssvar; taluppfattbarhet; kontaktmikrofon; överföringsfunktion; accelerometer; kommunikation; signal-brusförhållande;

    Sammanfattning : Contact microphones, especially throat microphones, have been developed to be used in environments with high background noises to improve the speech intelligibility in communication. They pick up vibrations from the surface they are attached to and are therefore less sensitive to sound and noise from the air. LÄS MER

  5. 4. Differentiation and classification of different materials on a touch-screen using a piezoelectric contact microphone

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Anders Björn; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this report, a potential improvement of an optical touch screen solution by means of acoustic sensing is presented. The goal is to utilize the different vibration patterns that arise when different materials touch the screen to be able to identify them. LÄS MER

  7. 5. En analys av ljudlatens i Windows 10 på tillgängliga enheter

    Kandidat-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Richard Ahlén; Robin Grönholm; [2016]
    Nyckelord :;

    Sammanfattning : This report is written during a project done by two students at Mälardalen University during the course DVA331. The purpose of this project was to determine if it was possible to reduce the latency on devices with Windows 10 to what is possible on an iOS device. LÄS MER
