  1. 21. Deriving Spectral Maps from JWST Data : A Study of Enceladus’ Plumes

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Stephan Weissenböck; [2023]
    Keywords : Data Analysis; Enceladus; Plumes; Atmosphere; JWST; NIRSpec; IFU; Infrared spectroscopy; Dataanalys; Enceladus; plym; atmosfär; JWST; NIRSpec; IFU; infraröd spektroskopi;

    Abstract : This study investigates the presence of water vapor plumes in the region south of Enceladus, a moon in the Saturnian system, through observations conducted by the James Webb Space Telescope. Enceladus is believed to harbor a subsurface ocean or localized water reservoir that gives rise to water geysers, expelling vapor into its tenuous atmosphere and outer space. READ MORE

  3. 22. Map Based Sensor Fusion for Lane Boundary Estimation on ADAS

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Puya Faghi; [2023]
    Keywords : Lane estimation; Lane detection; Map-matching; Sensor fusion; Smart camera; Vehicle Radar; Intelligent vehicle systems; Körfältsestimering; Körfältsdetektering; Kartmatchning; Sensorfusion; Smart Kamera; Radar system; Fordonsradar; Intelligenta fordonssystem;

    Abstract : A vehicles ability to detect and estimate its surroundings is important for ensuring the safety of the vehicle and passengers regardless of the level of vehicle autonomy. With an improved road and lane estimation, advanced driver-assistance systems will be able to provide earlier and more accurate warnings and actions to prevent a possible accident. READ MORE

  4. 23. Deep Neural Networks for Object Detection in Satellite Imagery

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Frederik Fritsch; [2023]
    Keywords : Object Detection; Satellite Imagery; Deep Neural Networks; YOLOv8; xView;

    Abstract : With the development of small satellites it has become easier and cheaper to deploy satellites for earth observation from space. While optical sensors capture high-resolution data, this data is traditionally sent to earth for analysis which puts a high constraint on the data link and increases the time for making data based decisions.

  5. 24. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Ideström; [2023]
    Keywords : Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Abstract : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. READ MORE

  6. 25. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Author : Nick Bergmans; [2023]
    Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Abstract : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. READ MORE
