  1. 31. Simulating distributed PV electricity generation on a municipal level : Validating a model for simulating PV electricity generation and implementing it for estimating the aggregated PV generation in Knivsta Municipality

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Lisa Molin; Sara Ericson; [2023]
    Nyckelord :photovoltaic generation model; model validation; artificial intelligence; machine learning; convolutional neural network; LIDAR;

    Sammanfattning :   The deployment of distributed photovoltaic (PV) is accelerating worldwide. Understanding when and where PV systems will generate electricity is valuable as it affects the power balance in the grids. One way of obtaining this information is simulating the PV power production of systems detected in Remotely Sensed Data (RSD). LÄS MER

  3. 32. Performance Estimation of a 1D pulsed LiDAR : A Study of SiPM-Based LiDAR in Ambient Light

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Joel Rune; [2023]
    Nyckelord :LiDAR; SiPM; SPAD; Ambient light; LiDAR; Kisel-fotomultiplikator; SPAD; Bakgrundsljus;

    Sammanfattning : LiDAR is a remote sensing technology that uses a laser to map the surrounding environment. With its many applications, for example in autonomous vehicles, LiDAR is a growing field within technology and research. The silicon photomultiplier (SiPM) is a solid state device commonly used in the receiving system of a LiDAR. LÄS MER

    Sammanfattning : Autonomous driving is a rapidly changing industry and has recently become a heavily focused research topic for vehicle producing companies and research organizations. These autonomous vehicles are typically equipped with sensors such as Light Detection and Radar (LiDAR) in order to perceive their surroundings. LÄS MER

  5. 34. Arbitrary motion Synthetic Aperture Radar

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Filip Alberius; Erik Rolander; [2023]
    Nyckelord :RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Sammanfattning : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. LÄS MER

  7. 35. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Klara Lindroth; [2023]
    Nyckelord :automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

    Sammanfattning : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. LÄS MER
