this research has been done for studying the effect of split application of nitrogen fertilizer on growth indexes and yield of three hybrids of grain corn in shahrood. a split plot experiment based on randomized complete block design with four replications was carried out in 2007. three hybrids of corn (double cross 370, single cross 447, single cross 499) were placed in main plots and split ap...

in this research, the effects of split application of nitrogen fertilizer on yield and yield component of three varieties of corn have been investigated. for this purpose, a split plot experiment on the base of randomized complete blocks in four replications was used. the main plots were three varieties of corn (370, 447 and 499), and sub plots were six split application of urea fertilizer trea...

This chapter presents a variety of applications of norms. These applications include governance in sociotechnical systems, data licensing and data collection, understanding software development teams, requirements engineering, assurance, natural resource allocation, wireless grids, autonomous vehicles, serious games, and virtual worlds.

This chapter addresses the problem of building normative multiagent systems in terms of regulatory mechanisms. It describes a static conceptual model through which one can specify normative multiagent systems along with a dynamic model to capture their operation and evolution. The chapter proposes a typology of applications and presents some open problems. In the last section, the authors expre...
