A water storage reanalysis over the European continent: assimilation of GRACE data into a high-resolution hydrological model and validation
Springer, Anne (2019-04-18)Continental water storage and redistribution within the Earth’s system are key variables of the terrestrial water cycle. Changes in water storage and fluxes may affect resources for drinking water and irrigation, lead to ... -
Development of a one-step 3D approach for the phase unwrapping process in a D-InSAR stack based on SBAS interferograms
Esch, Christina (2020)Differential Interferometric Synthetic Aperture Radar (D-InSAR) is a unique technique to detect and map deformations of the Earth's surface over large temporal and spatial scales. Processing a whole stack of multitemporal ... -
Visual Odometry and Sparse Scene Reconstruction for UAVs with a Multi-Fisheye Camera System
Schneider, Johannes (2020)Autonomously operating UAVs demand a fast localization for navigation, to actively explore unknown areas and to create maps. For pose estimation, many UAV systems make use of a combination of GPS receivers and inertial ... -
Active 3D Reconstruction for Mobile Robots
Palazzolo, Emanuele (2020)Mapping the environment with the purpose of building a 3D model that represents it, is traditionally achieved by trained personnel, using measuring equipment such as cameras or terrestrial laser scanners. This process is ... -
Visual Place Recognition in Changing Environments
Vysotska, Olga (2020)Localization is an essential capability of mobile robots and place recognition is an important component of localization. Only having precise localization, robots can reliably plan, navigate and understand the environment ... -
Extrinsic Calibration and Ego-Motion Estimation for Mobile Multi-Sensor Systems
Huang, Kaihong (2020)Autonomous robots and vehicles are often equipped with multiple sensors to perform vital tasks such as localization or mapping. The joint system of various sensors with different sensing modalities can often provide better ... -
Sensor fusion for localization of automated vehicles
Merfels, Christian (2020)Automated vehicles need to precisely know where they are at all times to be able to make informed driving decisions. Therefore, multiple localization systems are typically installed on such vehicles to provide redundant ... -
Robot mapping and navigation in real-world environments
Bogoslavskyi, Igor (2020)Robots can perform various tasks, such as mapping hazardous sites, taking part in search-and-rescue scenarios, or delivering goods and people. Robots operating in the real world face many challenges on the way to the ... -
Automatische, hochaufgelöste 3D-Phänotypisierung von Trauben und Beeren der Weinrebe unter Feldbedingungen
Rose, Johann Christian (2020)<em>Pilzwiderstandsfähige Sorten (PIWI) </em>sind eine der Innovationen im Weinbau. Das Projekt <em>Novel Viticulture Systems for sustainable production and products (NoViSys)</em> kombiniert die PIWIs zur Effizienzsteigerung ... -
Analysis and mitigation of site-dependent effects in static and kinematic GNSS applications
Zimmermann, Florian (2020)Satellitensignale unterliegen auf ihrem Weg von der Satelliten- zur Empfangsantenne einer Vielzahl an Einflüssen die zu Abweichungen führen. Heutzutage stellen in vielen Anwendungsbereichen insbesondere die stationsspezifischen ... -
Atmospheric refraction and turbulence in VLBI data analysis
Halsig, Sebastian (2018)The progress in further improving the quality of results derived by space-geodetic techniques observing in the radio frequency domain, such as Very Long Baseline Interferometry (VLBI) or Global Navigation Satellite Systems ... -
Hochwasserrisiko und Immobilienwerte: Zum Einfluss der Lage in überschwemmungs-gefährdeten Gebieten sowie zu den Folgen von Überschwemmungsereignissen auf den Verkehrswert von Wohnimmobilien
Kropp, Sebastian Alexander (2017)Aufgrund des fortschreitenden Klimawandels und dem weiteren Anstieg der Flächenversiegelung ist auch in Deutschland mit einer Zunahme extremer Hochwasserereignisse zu rechnen. Ein Anstieg des Hochwasserrisikos stellt ... -
Exploring urban structure to approach energy optimization: The case of residential settlement development in Dhaka city, Bangladesh
Sikder, Sujit Kumar (2017)The concept of energy optimization in urban development has the potential to address many urban challenges besides local energy concerns. Past research has attempted to combine the cross-cutting issues of urban planning, ... -
Conceptualizing the concept of disaster resilience: a hybrid approach in the context of earthquake hazard: case study of Tehran City , Iran
Asadzadeh, Asad (2017)From the natural perspective, disaster resilience is defined as the ability of a system or community to resist, mitigate, respond, and recover from the effects of hazards in efficient and timely manner. How urban communities ... -
