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 ...
Spatio-Temporal Registration Techniques for Agricultural Robots
(2021-06-16)
A critical challenge that we face today is to meet the rising demand for food, feed, fiber, and fuel from an ever-growing world population. We must meet this demand within the limited arable land available to us and do so ...
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 ...
Optimization of point grids in regional satellite gravity analysis using a Bayesian approach
(2020-03-25)
The subject of this thesis is the global and regional gravity field determination from GOCE data using the short arc approach. The focus is on the extension of the regional method regarding an adaption of the model resolution ...
Health and Welfare Implications of Climate Variability: Evidence from Rural Uganda
(2022-12-20)
Uganda has been highly affected by extreme weather events and climate change in the recent years. Weather-related disasters could potentially affect health outcomes directly, or indirectly through its deleterious effects ...
Efficient calibration strategies for panoramic terrestrial laser scanners
(2021-01-25)
Terrestrial laser scanner (TLS) measurements are unavoidably affected by systematic errors due to internal mechanical misalignments, while the calibration is the fundamental procedure for mitigating these effects and ...
Linking land use-land cover change with annual and perennial plant growth models for the spatio-temporal explicit simulation of ecosystem services: A case study in a savanna region of Ghana
(2023-08-30)
Many West African economies have been experiencing fast growth over recent decades. At the same time, their landscapes are also experiencing one of the fastest changes in the world, and the pace has accelerated over recent ...
