The mixture of Type I and Type II censoring schemes, called the hybrid censoring. This article presents the statistical inferences on lognormal parameters when the data are hybrid censored. We obtain the maximum likelihood estimators (MLEs) and the approximate maximum likelihood estimators (AMLEs) of the unknown parameters. Asymptotic distributions of the maximum likelihood estimators are used ...

Economic Load Dispatch (ELD) is an important optimization problem in the energy system. (ED) a short-term determination of optimal performance set power generation assets to meet system load at lowest possible cost, taking into account transmission and operational constraints. dispatch problems are solved by dedicated computer software that needs take limitations available resources correspondi...

The strong interaction between the discrete dynamic and the one continue is now seriously taken into account in the model. These models newborn so-called hybrid models describe at one time the two dynamics and are already used as well in control systems as in analysis. The methods and present tools of the dependability of systems are either of quantitative order or qualitative one. The avenue o...

Objective(s): Binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. Materials and Methods: Template free ZSM-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/ZSM-5 hybrid composites with nano chitosan...

Genetic diversity estimation of plant materials is one of the important pre-breeding activities in breeding field crops. Twenty-one microsatellite markers used to assess genetic diversity and relationship of 68 sunflower genotypes (Helianthus annuus L.). All of 21 pairs of SSR (Simple Sequence Repeats) markers produced a total number of 49 polymorphic bands. DNA fragments ranged from 9...
