Incremental Map Building with Markov Random Fields and its Evaluation
(2018-01-04)
This thesis presents a novel occupancy grid mapping approach which takes the dependencies of neighboring grid cells into account. The grid maps are estimated based on a compact environment representation which is derived ...
Extrinsic Calibration and Ego-Motion Estimation for Mobile Multi-Sensor Systems
(2018-12-20)
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 ...
Conceptualizing the concept of disaster resilience: a hybrid approach in the context of earthquake hazard: case study of Tehran City, Iran
(2017-05-19)
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 ...
Visual Place Recognition in Changing Environments
(2019-10-10)
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 ...
Phosphorus forms in fertilized arable soil profiles and related 33P uptake
(2019-09-13)
Arable soils usually store several thousand kg phosphorus (P) per ha, thus far exceeding the recommended P fertilizer dose to sustain crop yields. However, the soil profile is frequently not considered in fertilizer ...
Partitioning Water Vapor Fluxes by the Use of Their Water Stable Isotopologues: From the Lab to the Field
(2019-09-04)
Water stable isotopes are powerful tracers for partitioning of the terrestrial ecosystem water vapor fluxes into process-based components, i.e. evapotranspiration (ET) into soil evaporation (E) and plant transpiration (T). ......
Analysis and mitigation of site-dependent effects in static and kinematic GNSS applications
(2019-10-08)
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 ...
A water storage reanalysis over the European continent: assimilation of GRACE data into a high-resolution hydrological model and validation
(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 ...
