Parameters estimation methodology for the nonlinear rolling motion of finned cylindrical body (2018)
Journal Article

Identification of nonlinear roll dynamics of finned cylindrical bodies is a critical step when assessing free motion stability and trajectories of aerially dispensed munitions or decoys. In this paper the authors present a parameter estimation proces... Read More about Parameters estimation methodology for the nonlinear rolling motion of finned cylindrical body.

Reducing cost and size in photovoltaic systems using three-level boost converter based on fuzzy logic controller (2018)
Journal Article

Photovoltaic (PV) systems are dependent on two main factors of temperature and solar radiation, changing the PV system into a nonlinear system. Therefore, it is necessary to propose an intelligent control system for power control of PV systems to tac...

Measuring nonequibiaxial residual stresses and mechanical properties using Knoop indentation (2018)
Journal Article

A proper knowledge of the mechanical properties and residual stresses of materials has a significant role in the prediction of engineering failures. Indentation is a simple, nondestructive test that is capable of estimating both residual stresses and...

Assessing the joint probability of sea conditions: A robust approach (2018)
Presentation / Conference Contribution

The design of breakwaters and other coastal structures around the UK requires the assessment of the joint probability of extreme waves and sea levels. There is a standard simplified approach applied within the UK that uses joint exceedance contours o... Read More about Assessing the joint probability of sea conditions: A robust approach.

Time-dependent creep analysis and life assessment of 304 L austenitic stainless steel thick pressurized truncated conical shells (2018)
Journal Article

This paper presents a semi-analytical solution for the creep analysis and life assessment of 304L austenitic stainless steel thick truncated conical shells using multilayered method based on the first order shear deformation theory (FSDT). The cone i... Read More about Time-dependent creep analysis and life assessment of 304 L austenitic stainless steel thick pressurized truncated conical shells.

Failure analysis of bolt connections in fired heater of a petrochemical unit (2018)
Journal Article

The main function of a fired heater in a petrochemical site is to produce supersaturated steam. Due to extremely difficult working conditions and high temperatures, there is a very high probability of failures in different parts of a fired heater. In...

Robust control design for air breathing proton exchange membrane fuel cell system via variable gain second-order sliding mode (2018)
Journal Article

The nonlinear and time-dependent characteristic and unknown modeling uncertainty of proton exchange membrane fuel cell (PEMFC) such as complex electro-chemical, thermal, and fluid mechanic phenomena make its controller design quite challenging. In th... Read More about Robust control design for air breathing proton exchange membrane fuel cell system via variable gain second-order sliding mode.

Application of three nodded finite eleme (2018)
Journal Article

The convergence of numerical solution based on two nodded beam finite element require considerable number of
iterations and time; and is also plagued with shear locking. To address these deficiencies a three nodded beam element is
proposed in thi... Read More about Application of three nodded finite eleme.
