  1. 1. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Martin Åsell; [2024]
    Nyckelord :Inflow and Infiltration; I I; CNN; Linear regression;

    Sammanfattning : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. LÄS MER

  3. 2. Performance metrics and velocity influence for point cloud registration in autonomous vehicles

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

    Författare :Óscar Poveda Ruiz; [2023]
    Nyckelord :autonomous vehicle; localization; registration; metrics; error; classification; estimation; autonomt fordon; lokalisering; registrering; mätvärden; fel; klassificering; uppskattning;

    Sammanfattning : Autonomous vehicles are currently under study and one of the critical parts is the localization of the vehicle in the environment. Different localization methods have been studied over the years, such as the GPS sensor, commonly fused with other sensors such as the IMU. LÄS MER

  4. 3. Deep Neural Networks for dictionary-based 5G channel estimation with no ground truth in mixed SNR scenarios

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

    Författare :Matteo Ferrini; [2022]
    Nyckelord :5G; Channel Estimation; Sparse Linear Inverse Problem; Approximate Message Passing; Neural Networks; 5G; kanaluppskattning; sparsamt linjärt inversproblem; approximativ meddelandeöverföring; neurala nätverk;

    Sammanfattning : Channel estimation is a fundamental task for exploiting the advantages of massive Multiple-Input Multiple-Output (MIMO) systems in fifth generation (5G) wireless technology. Channel estimates require solving sparse linear inverse problems that is usually performed with the Least Squares method, which brings low complexity but high mean squared error values. LÄS MER

  5. 4. Development of an ICP-based Global Localization System

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Rebecka Nylén; Katherine Rajala; [2021]
    Nyckelord :localization; ICP; EKF; automatic control;

    Sammanfattning : The most common way to track the position of a vehicle is by using the Global Navigation Satellite System (GNSS). Unfortunately, there are many scenarios where GNSS is inaccessible or provides low precision, and it can therefore be vulnerable to only rely on GNSS. LÄS MER

  7. 5. Optical Detection and Altitude Estimation of Power Lines Relative to a UAV

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

    Författare :Carl Daniel Ahlberg; [2020]
    Nyckelord :;

    Sammanfattning : Inspection of power lines is a crucial activity to locate the source of power outages or to preemptively stop them. Visual inspection methods using optical cameras attached to Unmanned Aerial Vehicles (UAV) have become increasingly popular due to cheap operating costs, large areal coverage and the wide availability of these platforms.
