In this study, performance of object-oriented classification approach has been tested using medium resolution satellite dataset of Zonguldak testfield. For this purpose, Landsat 7 ETM+ and ASTER images were used because of their nearly similar ground sampling distance (GSD). As a first step, pan-sharpened images were created based on the combination of panchromatic and color bands available in ...

Overlay applications generate huge amounts of traffic in the Internet, which determines a problem for Internet Service Providers, since it results in high charges for inter-domain traffic. Traditional traffic management techniques cannot deal successfully with overlay traffic. An incentive-based approach that employs economic concepts and mechanisms is required in order to deal with the overlay...

We present a new hybrid BDD and SAT-based algorithm for model checking. Our algorithm is based on backward search, where each pre-image computation consists of an efficient All-SAT procedure. The All-SAT procedure exploits a graph representation of the model to dynamically prune the search space, thus preventing unnecessary search in large sub-spaces, and for identifying independent sub-problem...

Impervious surface area (ISA) is a key factor for monitoring urban environment and land development. Automatic mapping of impervious surfaces has attracted growing attention in recent years. Spectral built-up indices are considered promising to map ISA distributions due to their easy, parameter-free implementations. This study explores the potentials of impervious surface indices for ISA mappin...

This paper discusses the use of multitemporal remote sensing data for mapping and monitoring land cover in Acre State located in the western Brazilian Amazônia. According to IBGE vegetation maps, the study area is primarily covered by moist tropical forests (“Floresta Ombrofila Aberta”) that has been partially deforested during the last decades. The climate in Acre is classified as Am in the Ko...

Enterprise architecture management (EAM) is supposed to be a helpful means to support the management of enterprise transformations, i.e., fundamental changes. However, in current corporate practice, there seems to be no regular application of EAM as leading authority or support service for enterprise transformation. Thus, we examine, which activities need to be conducted in order to manage ente...
