    Simultaneous localization and mapping using single cluster probability hypothesis density filters 

    Lee, Chee Sing (Date of defense: 2015-09-01)

    The majority of research in feature-based SLAM builds on the legacy of foundational work using the EKF, a single-object estimation technique. Because feature-based SLAM is an inherently multi-object problem, this has led ...

    Sonar scan matching for simultaneous localization and mapping in confined underwater environments 

    Mallios, Angelos (Date of defense: 2014-05-15)

    This thesis presents the development of a localization and mapping algorithm for an autonomous underwater vehicle (AUV). It is based on probabilistic scan matching of raw sonar scans within a pose-based simultaneous ...

    Supporting competence development processes on open learning systems through personalization 

    Baldiris Navarro, Silvia Margarita (Date of defense: 2012-12-14)

    This thesis aim for promoting the learning objects economy by offering teacher the possibility of generating adaptive and standardized learning designs. The adaptation of the generated learning design considers two of the ...
