In this thesis, we developed a Bayesian approach to estimate the detailed composition of an unknown feedstock in a chemical plant by combining information from a few bulk measurements of the feedstock in the plant along with some detailed composition information of a similar feedstock that was measured in a laboratory. The complexity of the Bayesian model combined with the simplex-type constrai...

This paper considers the estimation methods for dynamic panel data (DPD) models with fixed effects, which suggested in econometric literature, such as least squares (LS) and generalized method of moments (GMM). These methods obtain biased estimators for DPD models. The LS estimator is inconsistent when the time dimension (T) is short regardless of the cross-sectional dimension (N). Although con...

A new variant of the accelerated over relaxation (AOR) method for solving systems of linear algebraic equations, the KAOR method is established. The treatment depends on the use of the extrapolation techniques introduced by Hadjidimos (1978) and the KSOR introduced by Youssef (2012) and its modified version published in (2013). The KAOR is an extrapolation version of the KSOR. This approach has...

An investigation of 55 bridge construction workers is reported. The overall bends rate was 097 %. (The term 'bends' as used in this study is defined in the paper.) Chokes were encountered in 67-27% of workers. A cli...

A total 98 school children were randomly assigned take part either 40-min sensory exploration cooking Jozef Youssef Kitchen Theory team (the experimental condition) or else cr...

Since the Intifada of 2000, living conditions in Gaza Strip have progressively deteriorated, and when Hamas came to power 2006–07, a complete blockade was enforced on inhabitants by Egypt Israel. In addition, five full-scale wars been waged Strip. Despite these conditions, Gazans remain resilient, as evidenced several recent cultural productions. This article analyses number films that endeavou...
