3D hydrological simulation of a forested headwater catchment: Spatio-temporal validation and scale dependent parameterization
Fang, Zhufeng (2016-09-30)Soil moisture plays a key role in the water and energy balance in soil, vegetation and atmosphere systems. There is a grand need to increase global-scale hyper-resolution water-energy-biogeochemistry land surface modelling ... -
3D Motion Analysis via Energy Minimization
Wedel, Andreas (2009-12-04)This work deals with 3D motion analysis from stereo image sequences for driver assistance systems. It consists of two parts: the estimation of motion from the image data and the segmentation of moving objects in the input ... -
3D Radar reflectivity assimilation with an ensemble Kalman filter on the convective scale
Bick, Theresa (2017-03-10)Atmospheric processes are governed by strongly nonlinear dynamics, and predicting convective events is a challenging task. In numerical weather prediction (NWP), an accurate description of the current state of the atmosphere ... -
3D Reconstruction of Plant Architecture by Grammar-based Modeling and Markov Chain Sampling
Schöler, Florian Erwin (2014-09-11)The world population is growing rapidly. As a consequence increasingly more products of crop plants are needed. Here, plant breeding gains a special significance. The goal of plant breeding is to develop new cultivars that ... -
3D-Modeling of unsaturated flow dynamics and pattern: Potentials and Limitations at different spatial and temporal scales
Cornelissen, Thomas Daniel (2016-06-14)The aim of this thesis was to evaluate the suitability of the physically based, distributed 3D hydrological model HydroGeoSphere for the simulation of spatio-temporal soil moisture variability as well as unsaturated flow ... -
3D-Silicon and Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
Pohl, David-Leon (2020-10-30)The future upgrade of the Large Hadron Collider to the High-Luminosity LHC demands new pixel detectors that can operate in environments with exceptionally high radiation. This requires investigations into new radiation-tolerant ... -
A LAsMA Survey of the Milky Way: Effects of Feedback on Molecular Clouds
Mazumdar, Parichay (2022-09-02)The advent of radio and (sub) millimetre astronomy has opened the world of molecular clouds (MCs) to astronomers' wonder. At the turn of the 21st century, MC surveys have helped us better understand them. How MCs form, ... -
