  1. 21. Analysis of wall-mounted hot-wire probes

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Alvisi Alex; Perez Adalberto; [2020]
    Keywords : Turbulent Boundary layer; Turbulent Channel Flow; Hot Wire Anemometer; Direct Numerical Simulations; Immersed Boundary Method;

    Abstract : Flush-mounted cavity hot-wire probes have been around since two decades, but have typically not been applied as often compared to the traditional wall hot-wires mounted several wire diameters above the surface. While the latter suffer from heat conduction from the hot wire to the substrate in particular when used in air flows, the former is belived to significantly enhance the frequency response of the sensor.

  3. 22. Traffic State Estimation for Signalized Intersections : A Combined Gaussian Process Bayesian Filter Approach

    University essay from KTH/Transportplanering

    Author : Michael Sederlin; [2020]
    Keywords : Traffic State Estimation; Traffic Flow modelling; Gaussian Processes; Bayesian Filtering; Kalman Filter; Traffic Signals; Intersection; Non-parametric;

    Abstract : Traffic State Estimation (TSE) is a vital component in traffic control which requires an accurate viewof the current traffic situation. Since there is no full sensor coverage and the collected measurementsare inflicted with random noise, statistical estimation techniques are necessary to accomplish this. READ MORE

  4. 23. Towards Robust Localization : Deep Feature Extraction with Convolutional Neural Networks

    University essay from Luleå tekniska universitet/Signaler och system

    Author : Erik Carlbaum Ekholm; [2020]
    Keywords : Autonomous Vehicles; MAVs; Visual Odometry; Localization; Convolutional Neural Networks; Optical Flow;

    Abstract : The ability for autonomous robotics to localize themselves in the environment is crucial and tracking the change of features in the environment is key for visual based odometry and localization. When shifting into rough environments of dust, smoke and poor illumination as well as erratic movements common in MAVs however, that task becomes substantially more difficult. READ MORE

  5. 24. Behaviour of NOx sensors at their end of life

    University essay from KTH/Förbränningsmotorteknik

    Author : Jose Mathew; [2020]
    Keywords : NOx sensor; failure modes; oscillatory fault monitor; diagnosis of sensors; NOx sensor; felfunktioner; oscillerande felmätare; diagnos av sensorer;

    Abstract : NOx-sensorn är grundläggande i det moderna efterbehandlingssystemet och dess pålitlighet är avgörande för att kunna leva upp till rådande emissionslagkrav. Livslängden samt sensorns beteende i slutet av denna varierar betydligt. READ MORE

  6. 25. Are you ok app

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Peder Nilsson; Kasper Kold Pedersen; [2020]
    Keywords : Fall detection; GPS; Android; Xamarin; IoT Hub; Azure; Stream Analytics; Smartphone; Emergency; System; Cloud storage;

    Abstract : Denna avhandling beskriver hur en smartphone-baserad larm-applikation som ger säkrare resor för cyklister och löpare kan konstrueras. Genom att övervaka och utvärdera GPS-data från telefonen över tid skickar den föreslagna applikations-prototypen, namngiven till Are You OK App (AYOKA), automatiskt SMS-meddelanden och initierar telefonsamtal till kontakter i en lista konfigurerad av användaren när densamme har råkat ut för ett fall.
