  1. 11. Arbitrary motion Synthetic Aperture Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Alberius; Erik Rolander; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 12. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Annachiara Nardone; [2023]
    Keywords : tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

    Abstract : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. READ MORE

  4. 13. Designing an Electric Road System

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : David Pålsson; Samuel Henley; [2023]
    Keywords : ERS; Electric Road System; Power Demand; Energy Storage; Peak Shaving; Emergency Backup; Elväg E20; Hallsberg; Örebro; Technology and Engineering;

    Abstract : Electric road systems (ERS) provide electric power to vehicles en route (dynamic charging) and can reduce the need for onboard battery capacity. This thesis sets out to examine the power demand of an ERS and the integration of energy storage in its power supply for grid load alleviation and backup power. READ MORE

  5. 14. Night-time Vehicle Detection Based on Observable Light Cues Using Deep Learning

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Celine Ivarsson; Jennifer Zacke; [2023]
    Keywords : Technology and Engineering;

    Abstract : This thesis investigates the issue of computer vision-based detection of oncoming cars during night-time, a critical road safety issue for automated high-beam assist. We propose a holistic image classification approach that uses deep learning methods to detect light artifacts from an oncoming car’s headlights before the car is entirely visible. READ MORE

  6. 15. Firefighting safety and efficiency in twin-tube city road tunnels

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Birgir þór Guðbrandsson; [2023]
    Keywords : Tunnel; safety; firefighting; fire department; säkerhet; brandbekämpning; räddningstjänst; Technology and Engineering;

    Abstract : Key question: Can firefighting tactics in twin-tube road traffic tunnels be made safer and more efficient through infrastructure design and installed equipment. Method: A literature study was conducted, and individuals in the Nordic countries with experience in the field were interviewed. READ MORE
