Experimental and numerical studies on solute transport in unsaturated heterogeneous porous media under evaporation conditions
(2012-08-31)
Groundwater level rise, root water uptake, or evaporation induces local upward water and solute fluxes in soils, causing soil salinization and rise of contaminants to the soil surface, and influencing the migration of ...
Planning and Implementation of the Dyke Systems in the Mekong Delta, Vietnam
(2011-04-05)
Floods are a dangerous threat and an implicit risk for farming communities in rural floodplains of the Mekong Delta (MD). The Vietnamese government decided the dyke system construction to control floods and ensure safety ...
Hierarchical and Spatial Structures for Interpreting Images of Man-made Scenes Using Graphical Models
(2012-02-02)
The task of semantic scene interpretation is to label the regions of an image and their relations into meaningful classes. Such task is a key ingredient to many computer vision applications, including object recognition, ......

Analysis of Water Use and Crop Allocation for the Khorezm Region in Uzbekistan Using an Integrated Hydrologic-Economic Model
(2011-04-20)
Sustainable and efficient water management is of central importance for the dominant agricultural sector and thus for the population and the environment of the Khorezm region. Khorezm is situated in the lower Amu Darya ...
Soil organic carbon pools and their spatial patterns: rapid assessment using mid-infrared spectroscopy
(2011-02-09)
Soil organic carbon (SOC) plays an important role in global C cycling. Until today, the spatial patterns of individual SOC fractions are, however, largely undiscovered as traditional methods for their determination are too ...
Automatische Detektion von Krankheiten auf Blättern von Nutzpflanzen
(2011-12-21)
In dieser Arbeit wird ein neuartiges, automatisches Verfahren zur Detektion von Krankheiten auf Blättern von Nutzpflanzen vorgestellt. Die Anwendung von Mustererkennungsverfahren zur Detektion von Blattkrankheiten ist noch ...
Hydrological Characterization of a Forest Soil Using Electrical Resistivity Tomography
(2010-07-13)
An explicit knowledge of soil properties is required in agronomy, nature conservation, and hydrology to characterize water storage and water flow processes, even more in the context of climate change. Electrical resistivity ...
Entwicklungsperspektiven metropolitaner Peripherien im Rahmen stadtregionaler Planungs- und Entwicklungsprozesse am Beispiel Nordrhein-Westfalen
(2013)
Die zurückliegenden Dekaden haben sich durch eine enorme Zunahme der Entwicklungsdynamiken von gesellschaftlichen, ökonomischen und ökologischen und daraus hervorgehend räumlichen Entwicklungen charakterisiert. Ein prägnantes ...
Management support by optimization-based trade-off analysis: the example of biodiesel crop production
(2014)
Modeling in decision support applications has often been used to compare outcomes between alternative scenarios of decision options. The introduction of optimization methods enable the comparison of a very large number of ...
Non-invasive monitoring of water and solute fluxes in a cropped soil
(2010-12-15)
Although the influence of root water uptake on solute transport is commonly recognized as important, it has barely been studied throughout the literature. However, plants take up a big amount of the infiltrating water and ...
