Greenhouse Gas Emissions from Composting and Anaerobic Digestion Plants
Nguyen Thanh, Phong (2012-10-16)Almost all biowaste collected in Germany is treated either by composting or by anaerobic digestion (AD). Both treatments result in greenhouse gas emissions. The main focus of the thesis was to quantify the contribution of ... -
Greenhouse Gases: Inventories, Abatement Costs and Markets for Emission Permits in European Agriculture: A Modelling Approach
Pérez Domínguez, Ignacio (2005)Greenhouse gas emissions from the agricultural sector are not yet fully included in the current international obligations on combating the effects of climate change. This is due to the fact that policy efforts have been ... -
Groundwater potential to supply population demand within the Kompienga dam basin in Burkina Faso
Sandwidi, Wennegouda Jean Pierre (2007)Groundwater recharge is constrained by various factors with rainfall playing a key role. The Kompienga dam basin located in southeastern Burkina Faso displays semi-arid climatic conditions with rainfall occurring five ... -
Grouping Uncertain Oriented Projective Geometric Entities with Application to Automatic Building Reconstruction
Beder, Christian (2007)The fully automatic reconstruction of 3d scenes from a set of 2d images has always been a key issue in photogrammetry and computer vision and has not been solved satisfactory so far. Most of the current approaches match ... -
