ABSTRACT-Nowadays farmers often use N-fertilizers to increase crop yield, but they lost quickly by leaching causes environmental contaminations that reported as most important source of pollutant. Although biofilters are useful for removing nitrate from drainage water, but many researches show that they need an external carbon source to sustain denitrification. Many researchers study on differe...

This paper uses theories of complexity, pace layering and resilience to address the question of tagging and folksonomies, and their influence on the practice of information architecture. User-centered tagging systems such as Flickr and del.icio.us have triggered diverse responses, both within and outside the community of information studies, because they differ so sharply from many standard app...

Visualizing dynamic graphs is challenging because changing node and edge attributes as well as topological alterations need to be encoded in the visual representation. However, existing approaches such as animation, juxtaposition, and superimposition do not scale well. In this poster we propose a novel layering approach for visualizing dynamic graphs where the graph for each point in time is a ...

Video coding for Internet applications faces major challenges. Due to the heterogeneity of the network, users with very different access bandwidths to the Internet want to receive videos of the best possible quality. A good coding scheme for layered video pursues the following major goal: it maximises the subjective visual quality at a given bandwidth. In this article, we present four different...
