  1. 1. Increasing Autonomy of Unmanned Aircraft Systems Through the Use of Imaging Sensors

    Författare :Piotr Rudol; Andrzej Szalas; Pascual Campoy; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UAV; UAS; UAV autonomy; human-body detection; color-thermal image fusion; vehicle tracking; geolocation; UAV indoor navigation;

    Sammanfattning : The range of missions performed by Unmanned Aircraft Systems (UAS) has been steadily growing in the past decades thanks to continued development in several disciplines. The goal of increasing the autonomy of UAS's is widening the range of tasks which can be carried out without, or with minimal, external help. LÄS MER

  2. 2. Movement ecology of aerial insectivorous birds : Individual-based studies on swifts and nightjars

    Författare :Gabriel Norevik; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; swift; nightjar; Apus; Caprimulgus; tracking; archival tags; GPS; geolocation; multi-sensor logger; migration; continuous flight; route choice; altitude; lunar cycle; seasonality;

    Sammanfattning : Many birds are predisposed to annually undertake movements over large temporal and spatial scales. They have an efficient flight machinery, demonstrate impressive capacities in storing and burning fuel, and they exhibit necessary orientation and navigational skills. LÄS MER

  3. 3. Enhancing Tropospheric Humidity Data Records from Satellite Microwave and Radiosonde Sensors

    Författare :Isaac Moradi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CDR; climate; microwave; radiosonde; water vapor; remote sensing; antenna; homogenization; humidity; meteorology; troposphere; radio-frequency;

    Sammanfattning : Water vapor is the most dominant greenhouse gas and plays a critical role in the climate by regulating the Earth's radiation budget and hydrological cycle. A comprehensive dataset is required to describe the temporal and spatial distribution of water vapor, evaluate the performance of climate and weather prediction models in terms of simulating tropospheric humidity, and understand the role of water vapor and its feedback in the climate system.

  4. 4. Clustering in the Big Data Era: methods for efficient approximation, distribution, and parallelization

    Författare :Amir Keramatian; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clustering; Approximation-based synopsis; Distributed and Parallel Processing; Applied ML;

    Sammanfattning : Data clustering is an unsupervised machine learning task whose objective is to group together similar items. As a versatile data mining tool, data clustering has numerous applications, such as object detection and localization using data from 3D laser-based sensors, finding popular routes using geolocation data, and finding similar patterns of electricity consumption using smart meters.
