In this paper, a design framework is presented for integrating the various perspectives and major investigation aspects of ubiquitous smart spaces. A key problem in developing ubiquitous smart spaces is how to design a physical space that maps to the underlying computing infrastructure and the corresponding patterns of situated interactions in every life. This paper explores design methods and ...

Theories of species coexistence have played a central role in ecology and evolutionary studies of the origin and maintenance of biodiversity in highly diverse communities. The concept of niche and associated theories predict that competition for available ecological space leads to a ceiling in species richness that influences further diversification patterns. By contrast, the neutral theory sup...

in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...
