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 ...
Determination and verification of possible resource savings in manual dishwashing
(2011-07-14)
Many tests and consumer surveys have shown that manual dishwashing at home is done in very different ways, taking also different amounts of resources. Because almost every household, whether owning an automatic dishwasher ...
Soil erosion modeling and soil quality evaluation for catchment management strategies in northern Ethiopia
(2011-11-02)
About 85% of the Ethiopian population is engaged primarily in agriculture. However, changing environmental factors have led to soil quality (SQ) degradation that poses a critical risk for food security. But, despite some ...
Resource utilization and sustainability of conservation-based rice-wheat cropping systems in Central Asia
(2011-08-26)
Excessive and inefficient water use, intensive soil tillage and decreasing soil fertility have caused land degradation and desertification, which are threatening the sustainability of rice-wheat systems in the irrigated ...
The effect of phosphorus amendments on nitrogen fixation and growth of trees on salt-affected croplands in the lower reaches of Amu Darya, Uzbekistan
(2011-12-07)
Afforestation, particularly with the use of N2-fixing trees (NFTs), is an option for ecological restoration of salinized, irrigated croplands in the lower reaches of the Amu Darya River. But current knowledge of enhanced ...
Futtermittelkundliche und ernährungsphysiologische Bewertung von Rapskuchen für Milchkühe
(2011-08-02)
In den letzten Jahren war ein ständig zunehmender Rapsanbau in der Bundesrepublik Deutschland zu verzeichnen. Gründe hierfür waren eine erhöhte Biodieselnachfrage sowie die Nutzung von Rapsöl in der Humanernährung. Als ...
