Wet Path Delay Corrections from Line-of-Sight Observations of Effelsberg’s Water Vapour Radiometer for Geodetic VLBI Sessions
(2012-08-01)
Water vapour induced excess path lengths in electromagnetic waves have been one of the most unmanageable errors in space geodesy, such as GPS and VLBI. The difficulty mainly comes from the highly variable distribution of ...
Attributierte Grammatiken zur Rekonstruktion und Interpretation von Fassaden
(2012-03-19)
Dem Bedarf und Nutzen hoch detaillierter 3D-Stadt- und Gebäudemodelle steht deren aufwendige Erfassung gegenüber. Ist die automatische Ableitung vereinfachter Dachstrukturen aus Luftbildern oder Laseraltimetrie weitestgehend ...
Assessing People´s Early Warning Response Capability to Inform Urban Planning Interventions to Reduce Vulnerability to Tsunamis: Case Study of Padang City, Indonesia
(2014-03-10)
In the last decade, more emphasis is given on the human aspect of early warning or the attribute of “people-centered” early warning systems. This study seeks to better understand the specific conditions that shape people´s ...
Sorption, Transformation and Transport of Sulfadiazine in a loess and a sandy Soil
(2014-12-10)
Veterinary antibiotics are unintentionally introduced into the environment and therefore found in ground and surface water, soil and sediments, air, plants etc. They enter these compartments mainly via application of manure ...
Statistical Signal Decomposition Techniques for Analyzing Time-Variable Satellite Gravimetry Data
(2014-09-29)
The time-variable gravity fields from the Gravity Recovery and Climate Experiment (GRACE) satellite mission provide valuable information about total water storage variations on a global scale. This quantity is difficult ...
On High Performance Computing in Geodesy: Applications in Global Gravity Field Determination
(2014-12-08)
Autonomously working sensor platforms deliver an increasing amount of precise data sets, which are often usable in geodetic applications. Due to the volume and quality, models determined from the data can be parameterized ...
Modeling soil erosion and reservoir sedimentation at hillslope and catchment scale in semi-arid Burkina Faso
(2011-08-23)
Soil erosion is a major factor of land degradation in Sub-Saharan Africa. The loss of nutrient-rich topsoil from hillslopes causes severe agricultural problems for an extremely vulnerable agricultural society that depends ...
Entwicklung eines Kalman-Filters zur Bestimmung kurzzeitiger Variationen des Erdschwerefeldes aus Daten der Satellitenmission GRACE
(2011-07-14)
Eine wichtige Beobachtungsgröße bei der Erforschung des Erdsystems stellt das Gravitationsfeld der Erde dar, dessen zeitliche Variationen mit der Satellitenmission GRACE (Gravity Recovery And Climate Experiment) erstmals ......
Development of a Kalman filter to derive short-term variations of the Earth's gravity field from GRACE data
The gravitational field and its temporal variations represent an important observable for ......

Ökonomisches Entscheidungstool zur Wohnbaulandentwicklung: Wirtschaftlichkeitsanalysen potenzieller Wohnbauflächen auf der Ebene des Flächennutzungsplanes
(2011-05-18)
Die aktuellen Trends der Siedlungsflächenentwicklung führen in Verbindung mit der demographischen Entwicklung in Deutschland zu hohen Anforderungen an die langfristige Wirtschaftlichkeit von Wohnbauflächen. Da vor allem ...
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 ...
