A comprehensive experimental and numerical study on redistribution of residual stresses by shot peening (2015)
Journal Article

Shot peening is one of the most effective surface strengthening treatment technologies in which compressive residual stresses are induced beneath the specimen surface. Effects of various factors on the distribution of residual stress profile induced...

Spherical indentation, part II: Experimental validation for measuring equibiaxial residual stresses (2015)
Journal Article

It is occasionally important or even inevitable to measure residual stresses without harming engineering components. Spherical indentation can be categorized as a nondestructive method to measure residual stresses, as it causes very little damage to...

Stress variations effect on the accuracy of slitting method for measuring residual stresses (2015)
Journal Article

To maintain the structural integrity of the engineering components, having an exact knowledge of residual stresses is important. Among all mechanical strain relief techniques to measure residual stresses, slitting is one of the youngest. This techniq...

Influence of asymmetrical cuts in measuring residual stresses using contour method (2015)
Journal Article

Experimental methods to determine residual stresses are mainly divided into destructive and non-destructive categories. Contour method is a destructive technique that offers a two dimensional map of normal component of residual stresses. The conventi...

Control of oxygen excess ratio in a PEM fuel cell system using high-order sliding-mode controller and observer (2015)
Journal Article

The main objective of this manuscript is to design a high-order sliding-mode observer to provide finite time estimation of unmeasurable states (x4 : oxygen mass, x5 : nitrogen mass) together with the oxygen excess ratio (ratio of the input oxygen ow...

Production of biodiesel from TGX-1778 soybeans (glycine max) by sodium hydroxide-catalyzed transesterification (2014)
Journal Article

This study investigated the potential of a Nigerian-grown soyabean (TGX-1778) to produce biodiesel.
The Soybeans at room temperature, were dehulled, ground to a powdery form, and the oil extracted by
Soxhlet extraction method using n-Hexane. 50 ml... Read More about Production of biodiesel from TGX-1778 soybeans (glycine max) by sodium hydroxide-catalyzed transesterification.
