  1. 1. Experiments with Visual Odometry for Hydrobatic Autonomous Underwater Vehicles

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

    Author : Somnath Balaji Suresh Kumar; [2023]
    Keywords : Hydrobatic AUVs; VO; Stonefish; ORB-SLAM2; VISO2; Hydrobatiska AUV:er; VO; Stonefish; ORB-SLAM2; VISO2;

    Abstract : Hydrobatic Autonomous Underwater Vehicles (AUVs) are underactuated robots that can perform agile maneuvers in challenging underwater environments with high efficiency in speed and range. The challenge lies in localizing and navigating these AUVs particularly for performing manipulation tasks because common sensors such as GPS become very unreliable underwater due to their poor accuracy.

  3. 2. Doppler radar odometry for localization in difficult underground environment

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Emil Fritz; Annika Nilsson; [2023]
    Keywords : SLAM; Localization; Mappers; Odometry; Drift; RIO; Radar; Lidar; IMU;

    Abstract : Accurate and efficient localization is a fundamental requirement for autonomous operation of robots, especially in areas that deny global navigation services. Localization is even more challenging in environments that present visual and geographic difficulties. READ MORE

  4. 3. Dataset Drift in Radar Warning Receivers : Out-of-Distribution Detection for Radar Emitter Classification using an RNN-based Deep Ensemble

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Kevin Coleman; [2023]
    Keywords : Radar Emitter Classification; Pulse Descriptor Word; Out of Distribution Detection; Dataset Drift; Uncertainty Estimation; Deep Ensembles; Recurrent Neural Networks; LSTM;

    Abstract : Changes to the signal environment of a radar warning receiver (RWR) over time through dataset drift can negatively affect a machine learning (ML) model, deployed for radar emitter classification (REC). The training data comes from a simulator at Saab AB, in the form of pulsed radar in a time-series. READ MORE

  5. 4. Drivers of flower size evolution in the selfing species Arabidopsis thaliana

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Clàudia Fernández Mestre; [2023]
    Keywords : Arabidopsis thaliana; petal size; fitness; selection; evolutionary drivers; GWAS;

    Abstract : The influence of pollinators on the evolution of flower morphology has been extensively explored. Yet, the effect of other ecological factors, such as genetic drift, environmental filtering, and allometric constraints, gained less attention. In this study, we addressed the importance of those drivers in a predominantly selfing species. READ MORE

  6. 5. Lidar data processing for railway catenary systems

    University essay from Luleå tekniska universitet/Drift, underhåll och akustik

    Author : Daniël Voorwald; [2022]
    Keywords : lidar data processing; linearity; surface variation; overhead catenary systems; railway infrastructure;

    Abstract : Railway Catenary systems play a crucial role in the safe and reliable transportation of goods and people throughout the world. Monitoring the catenary infrastructure is crucial for safety purposes and therefore requires inspections. However, the current inspection methods are not sufficient for detecting all possible failure modes. READ MORE
