On the theory and application of model misspecification tests in geodesy
(2007)
Many geodetic testing problems concerning parametric hypotheses may be formulated within the framework of testing linear constraints imposed on a linear Gauss-Markov model. Although geodetic standard tests for such problems ...
On Monte Carlo methods with applications to the current satellite gravity missions
(2007)
Large-scaled least squares problems require tailored numerical techniques to overcome the computational burden. For these types of problems iterative strategies are suitable because of their flexibility and effectiveness. ...
Visual SLAM from image sequences acquired by unmanned aerial vehicles
(2009-12-08)
This thesis shows that Kalman filter based approaches are sufficient for the task of simultaneous localization and mapping from image sequences acquired by unmanned aerial vehicles. Using solely direction measurements to ...
Konzept zur Harmonisierung und Präsentation von Nutzungsdaten auf Grundlage des 3A-Modells
(2010-06-04)
Mit dem AFIS®-ALKIS®-ATKIS®-Anwendungsschema hat die AdV ein modernes Konzept zur integrierten Führung der Geobasisdaten des amtlichen Vermessungswesens geschaffen. Die verschiedenen Grunddatenbestände des Liegenschaftskatasters, ...
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 ...
Robust Wide-Baseline Stereo Matching for Sparsely Textured Scenes
(2011-08-19)
The task of wide baseline stereo matching algorithms is to identify corresponding elements in pairs of overlapping images taken from significantly different viewpoints. Such algorithms are a key ingredient to many computer ...
Separablity of deformations and measurement noises of GPS time series with modified Kalman filter for landslide monitoring in real-time
(2011-08-04)
The separation of the deformations and measurement noise of GPS coordinate time series and accuracy improvement of GPS real-time coordinates are major aspects of the thesis. In order to reduce the influence of the colored ...
Ein hierarchischer Ansatz zur Interpretation von Gebäudeaufnahmen
(2012-06-20)
Durch die Fortschritte bei der 3D-Visualisierung von Landschaften und urbanen Räumen in den vergangenen Jahren wächst die Nachfrage nach semantischen und detailgenauen 3D-Stadtmodellen. Die Interpretation von Digitalbildern ...
Konsistente Kombination von Schwerefeld, Altimetrie und hydrographischen Daten zur Modellierung der dynamischen Ozeantopographie
(2012-07-18)
Die dynamische Ozeantopograpie als Differenz zwischen Meeresoberfläche und dem Geoid reflektiert charakteristische Merkmale der Ozeanzirkulation und stellt als gemessene Größe somit eine bedeutende Eingangsgröße in ...
Role of termites for the distribution patterns of carbon and phosphorus fractions and the genesis of tropical soils, Brazil
(2012-07-27)
Tropical soil fertility is limited by low phosphorus (P) availability, limited accumulation of organic matter and by advanced stages of pedogenesis. Termites are well-known soil-engineers, which accumulate clay, organic ......
Die Bedeutung von Termiten für die Verteilungsmuster von Kohlenstoff- und Phosphor-Fraktionen sowie die Genese Tropischer Böden, Brasilien
Die Bodenfruchtbarkeit in den Tropen ist durch eine geringe ......
A fertilidade dos solos tropicais é limitada pela baixa disponibilidade de fósforo, a falta de acumulação de matéria orgânica, e por estados avançados de pedogênese. Os térmitas ou cupins são bem-conhecidos 'engenheiros ......
