  1. 1. A Structural Analysis of the Fracture Sets in Gothenburg, Sweden: A Remote Sensing and Manual Lineament Approach

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jacek Krysik; [2023-05-22]
    Nyckelord :Remote sensing; Manual lineament analysis; Fractal analysis; Structural; Regional geology; LiDAR; Gothenburg region;

    Sammanfattning : The fracture-valley landscape within the Gothenburg region was analysed based on LiDAR-derived hillshade images as well as several sources of orthomosaics. Using a manual lineament interpretation approach and complimented with an objective fractal analysis software (FROST), the objective of the study was to characterise the regional fracture sets as well as attempt to link the sets to the complex regional geological history.

  3. 2. Autonoma fordon och det framtida samhället

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Linus Sallander; [2023]
    Nyckelord :Autonoma fordon; uppbyggnad; sensorer; historia; utveckling; säkerhet; ansvar; hållbarhet; trafikflöde; framtid;

    Sammanfattning : Denna rapport är ett kandidatexamensarbete vid Kungliga Tekniska Högskolan och ärämnat att fungera som en handbok för autonoma fordon, detta genom att arbetet är indelati tre huvudområden; det autonoma fordonets uppbyggnad, det autonoma fordonetshistoria samt det autonoma fordonets roll i det framtida samhället. Syftet med arbetet äratt ge en övergripande helhetsbild av dessa tre områden. LÄS MER

  4. 3. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jessica McKenna; [2023]
    Nyckelord :Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Sammanfattning : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  5. 4. Point Cloud Registration using both Machine Learning and Non-learning Methods : with Data from a Photon-counting LIDAR Sensor

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Maja Boström; [2023]
    Nyckelord :Point Cloud Registration; Machine Learning; Photon-counting LIDAR; Iterative Closest Point;

    Sammanfattning : Point Cloud Registration with data measured from a photon-counting LIDAR sensor from a large distance (500 m - 1.5 km) is an expanding field. Data measuredfrom far is sparse and have low detail, which can make the registration processdifficult, and registering this type of data is fairly unexplored. LÄS MER

  7. 5. DRONAR: Obstacle echolocation using ego-noise

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Henrik Nilsson; [2023]
    Nyckelord :Drone; Autonomous systems; Obstacle avoidance; Sound; Noise; Planning; SONAR; Ego-noise; Multi-rotor aerial vehicle; Unmanned areal vehicle; Drönare; Autonoma system; Hinderundvikning; Ljud; Oljud; Planering; SONAR; Egenljud; Multirotorfordon; Obemannat luftfordon;

    Sammanfattning : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. LÄS MER
