Adaptive critic (AC) based controllers are typically discrete and/or yield a uniformly ultimately bounded stability result because of the presence of disturbances and unknown approximation errors. A continuous-time AC controller is developed that yields asymptotic tracking of a class of uncertain nonlinear systems with bounded disturbances. The proposed AC-based controller consists of two neura...

Process yield has been an essential criterion used for manufacturing industries in business management. Quality managers and engineers involved in factories require capability analyses to access process yields, particularly, for processes with a very low fraction of defectives. It is noted that the accuracy of process yield is important; as it is one of major considerations for supplier selecti...

this study was conducted to investigate the genotype¬×¬environment interaction effects on yield and yield components of wheat. ten cultivars of wheat were evaluated in 8 environments (combinations of two levels of nitrogen and four irrigation regimes) in growing season of 2006-2007 at the research farm of isfahan university of technology. based on the stability parameters of eberhart and russel...

in order to investigate the yield stability of eight promising rice genotypes, these lines along with shiroudi and fajr cultivars as control were sown in three regions of mazandaran province (amol, sari and tonekabon) as randomized complete block arrangements with three replications in 2012 and 2013. analysis of variance for grain yield indicated significant differences among the genotypes in a...

nowdays, production of high quality engine oils is one of the worries of our country’s engine oil industry. in this study, the behavior of four commercial polymers used in nation motor oil industry in obtaining the best viscosity index improver was investigated. in this regard, viscometric behavior, shear stability and polymers’ performance for engine cranking were compared at low temperature. ...

In order to assess the reliability of power systems, transient stability simulations must be conducted in addition to steady state study. The transient stability component of reliability studies usually involves extensive simulations generating large amounts of data to be analyzed. Conventional stability analysis relies on a visual examination of selected simulation data plots to classify the s...

introduction: β-glucan is the most important water soluble fiber found in cell wall of some cereals such as barley, oat, wheat and rye, that are composed of β-d-glucoseunits with (1→4) (70%) and (1→3) (30%)anomericbonds(benito-román, alonso, & cocero, 2013).β-glucan is regarded as a dietary fiber in functional foods. it can act as a hydrocolloid due to its thickening characteristic in aqueous p...
