Graph Partitioning for the Finite Element Method: Reducing Communication Volume with the Directed Sorted Heavy Edge Matching
(2019-05-07)A technique called the Finite Element Method is primarily utilized to numerically solve Partial Differential Equations, most commonly by the use iterative methods, over a compact domain. The partial differential equations ... -
Graph-based Object Understanding
(2021-06-18)Computer Vision algorithms become increasingly prevalent in our everyday lives. Especially recognition systems are often employed to automatize certain tasks (i.e. quality control). In State-of-the-Art approaches global ... -
Graphen auf Siliziumcarbid: elektronische Eigenschaften und Ladungstransport
(2014-06-10)In this thesis the local electronic as well as charge transport properties down to atomic length scales of epitaxial graphene on the SiC(0001) surface are investigated. To achieve this, next to well known scanning probe ... -
Grass growth, matter turnover and herbage production in temperate silvopastoral systems
(2022-12-07)In recent times, silvopastoral systems gain increasing attention due to their various ecological and economic benefits. They have the potential to be a more sustainable alternative to common intensive land-use practices ... -
Grassland management with horses: Its role in grassland utilization in Germany and the effects on grassland vegetation
(2021-01-19)Grazing is a well known management tool to increase and maintain species richness in grasslands. Generally, livestock grazing enhances sward structural heterogeneity due to dietary choices, trampling, nutrient cycling and ... -
Gravitational Microlensing: GPU-based Simulation Algorithms and the Information Content of Light Curves
(2011-07-22)The simulation of gravitational microlensing light curves is a time-consuming effort, but essential for confirming potential planetary microlensing events. In this thesis a point-wise binary ... -
Green algae in soil: assessing their biodiversity and biogeography with molecular-phylogenetic methods based on cultures
(2016-02-04)Green microalgae (Chlorophyta) dominate soils in the northern temperate climate zone, however, their biodiversity is still poorly understood. Available diversity inventories rely on light microscopy and morphospecies, which ... -
Grenzflächen- und Verspannungseffekte in La₁₋ₓSrₓMnO₃-Dünnschichten
(2024-12-19)In this dissertation, strain and interface effects on La₁₋ₓSrₓMnO₃ (LSMO) thin films with doping levels 0 ≤ x ≤ 0.6 are investigated by Raman spectroscopy and surface-enhanced Raman spectroscopy (SERS). For undoped LaMnO₃, ... -
Grenzflächeneffekte in Manganatschichten
(2008-01-07)Interfaces play a major role in manganites and magnetoresistive systems. Thus, this work deals with the systematic analysis of the influence of interfaces on the transport properties of ... -
Gromov-Wasserstein Distances and their Lower Bounds
(2022-11-25)In various applications in biochemistry, computer vision and machine learning, it is of great interest to compare general objects in a pose invariant manner. Recently, the following approach has received increased attention: ... -
Gross N2O emission and gross N2O uptake in temperate cropland agroforestry and monoculture systems
(2022-02-24)Nitrous oxide (N2O) is a powerful greenhouse gas and also the remaining threat to the ozone layer. N2O emission is mainly from cropland accounting for 82% of the global N2O increase, which is of great concern for policymakers ... -
Gross N2O fluxes across soil-atmosphere interface and stem N2O emissions from temperate forests
(2017-05-22)Although nitrous oxide (N2O) is a minor constituent of the atmosphere, it is still of great concern. This is because N2O can significantly affect the physics and chemistry of the atmosphere and thus influence the climate ... -
Ground State Depletion Fluorescence Microscopy
(2008-01-16)Microscopy is one of the most important analysis tools of modern science. One defining attribute of a microscope is its resolution as it specifies the minimum distance at which one can ... -
Groundwater Use and Management along the Rural-Urban Interface:
(2019-11-15)Groundwater has become one of the most important freshwater sources worldwide. Population growth, socio-economic development, changing consumption patterns as well as the expansion of irrigated agriculture have increased ... -
Group coordination during collective movements in Guinea baboons (Papio papio)
(2019-11-08)Despite potentially diverging interests, members of social groups coordinate to maintain group cohesion. The mechanisms and processes of group coordination are modulated by species- and context-specific factors. The genus ... -
Group Coordination Processes and Determinants of Leadership in Red-fronted Lemurs (Eulemur rufifrons)
(2019-12-13)For animals to enjoy the benefits of group living it is vital that they coordinate their activities despite divergent needs. The challenge this poses becomes apparent when animals are moving between resources. In this ... -
Groupoids in categories with partial covers
(2019-02-07)Meyer and Zhu survey the general theory of groupoids, groupoid actions, groupoid principal bundles, and various kinds of morphisms between groupoids in the framework of categories with pretopology. We modify the categorical ... -
Growth and Characterization of Carbon-Metal-Nanocomposite-Thin-Films and Self-Organized Layer Growth
(2009-06-09)The simultaneous deposition of carbon and metal ions by mass-selected ion beam deposition leads to the formation of carbon-metal-nanocomposites. The morphology of the resulting films depends ... -
