to study of genetic diversity of rapeseed genotypes using multivariate methods under normal and drought stress conditions, 16 genotypes were evaluated using a randomized complete blocks design with three replications in razi university in 2007-08 cropping season. factor analysis under normal condition showed that nine factors explained 89.05 percentage of total data variation, and under drought...

Aiming at the Present Condition of Research on soybean growth model, in order to recur the overall dynamic process of soybean growth, we parameterized the main factors that can affect the plants’ physical development and built the soybean plant growth model by adopting the classical biologic plant growth logistic equation and the Self-similarity of plant morphology. In VC6.0 environment, we app...

A common strategy for control systems is to design a set of controllers for a given plant (i.e., the system to be controlled). The controller that is chosen to be implemented at any given time depends on the current operating condition of the plant. For example, a plant operating in nominal condition generally uses one controller, while a plant with a fault uses a different controller. The pred...
