Analysis of Land Surface Dynamics in Ukraine Observed by Satellite Sensors
(2020-06-18)
Land surface changes, induced by anthropogenic or climatic drivers, can dramatically impact ecosystem functioning. The growing amount of data from remote sensing and complementary data sources greatly supports the ...
Algebraic, logical and stochastic reasoning for the automatic prediction of 3d building structures
(2021-01-26)
3D building models are nowadays an important prerequisite for many applications such as rescue management or navigation tasks. However, most approaches for the automatic reconstruction of buildings rely on high-resolution ...
Plant Classification Systems for Agricultural Robots
(2021-03-16)
Due to a continually growing world population, the demand for food and energy increases continuously. As a central source of food, feed, and energy, crop production is therefore called upon to produce higher yields. To ...
Exact Optimization Algorithms for the Aggregation of Spatial Data
(2020-12-16)
The aggregation of spatial data is a recurring problem in geoinformation science. Aggregating data means subsuming multiple pieces of information into a less complex representation. It is pursued for various reasons, like ...
Investigations to quantify individual exposure to solar ultraviolet erythemal radiation including cloud meteorological impact
(2020-07-09)
Combined meteorological and dosimetric ultraviolet (UV) erythemal radiation (UVER) measurements were performed in 2016 and 2017. Based on collected data sets the actual UVER exposure of outdoor working probands is determined ...
Networks, translocality, and the resilience of rural livelihoods in Northeast Thailand: Insights from a social network perspective
(2022-03-24)
This dissertation aims to substantiate the ongoing debate on migration and its role in resilience building, and in particular in building resilient rural livelihoods amidst rural transformation and climate change. For a ...
Improvement of hail detection and nowcasting by synergistic combination of information from polarimetric radar, model predictions, and in-situ observations
(2020-10-21)
Large hail can pose a major threat to people, infrastructure, and property. While polarimetric radar observations enable us to reliably detect hail, discrimination of hail size and strategies to nowcast and predict hail ...
Underwater flight in sea turtles and plesiosaurs: Dissection, muscle reconstructions, analog models, and finite element structure analyses inform on flipper twisting and muscle forces in plesiosaurs
(2020-08-13)
This dissertation contributes to our understanding of plesiosaur locomotion by providing foreflipper and hindflipper muscle reconstructions and studying aspects of their muscle physiology (functions, forces, muscle length ......
High Performance Computing in Basin Modeling: Simulating Mechanical Compaction with the Level Set Method
(2020-07-09)
The evolution of sedimentary basins is a complex set of processes developing over millions of years. Often, tectonic activity will create accommodation space that is filled in with sediments. These sediments undergo changes ...
Efficient Semantic Scene Understanding for Mobile Robots
(2021-12-16)
Over the last few years, robots have been slowly making their way into our everyday lives. From robotic vacuum cleaners picking up after us already working in our homes, to the fleets of robo-taxis and self-driving vehicles ...
