Time-dependent thermo-elastic creep analysis of thick-walled spherical pressure vessels made of functionally graded materials (2015)
Journal Article

Assuming that the thermo-elastic creep response of the material is governed by Norton's law and material properties, except Poisson's ratio, are considered as a function of the radius of the spherical vessel, an analytical solution is presented for c...

Fuzzy PID control of a stand-alone system based on PEM fuel cell (2015)
Journal Article

Fuel cell (FC) systems are appropriate candidates as alternative energy sources for use in stand-alone applications. However, the FC generates an unregulated voltage, which is not suitable in stand-alone application usage solely. This paper presents...

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...

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...

The use of exploratory research in addressing knowledge issues in delivering sustainable retrofitted building projects (2015)
Presentation / Conference Contribution

This paper describes a proposed strategy of exploring the role of knowledge management (KM) in delivering retrofitted building projects. This is based on an on-going PhD project whose primary objective is to develop a decision support system (DSS) fo...

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...
