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.

Time-dependent thermo-creep analysis of rotating FGM thick-walled cylindrical pressure vessels under heat flux (2014)
Journal Article

In the present study, time-dependent thermoelastic creep response for isotropic rotating thick-walled cylindrical pressure vessels made of functionally graded material (FGM) has been investigated, taking into account the creep behavior of the FGM pre...

Face recognition via edge-based Gabor feature representation for plastic surgery-altered images (2014)
Journal Article

Plastic surgery procedures on the face introduce skin texture variations between images of the same person (intra-subject), thereby making the task of face recognition more difficult than in normal scenario. Usually, in contemporary face recognition... Read More about Face recognition via edge-based Gabor feature representation for plastic surgery-altered images.

Treatment of Automotive Gas Oil (AGO)-contaminated water using activated carbon from Indian bamboo (2014)
Journal Article

This study investigated the ability of activated carbon extracted from Nigerian-grown Indian bamboo, to absorb hydrocarbon from automotive gas oil -contaminated water. The water was polluted in the ratio of 3:1 (that is, 3parts of water to 1part of a...

Investigation of ground water quality during the dry season in Rivers State, Nigeria: A case study of Port Harcourt Metropolis (2014)
Journal Article

This research is to investigate the quality of ground water in boreholes and hand-dug wells during the dry season in six locations in Port Harcourt metropolis of Rivers State. The locations are Rumuola, D-line and Trans-Amadi, which use borehole whil...

Effect of heat flux on creep stresses of thick-walled cylindrical pressure vessels (2014)
Journal Article

Assuming that the thermo-creep response of the material is governed by Norton's law, an analytical solution is presented for the calculation of time-dependent creep stresses and displacements of homogeneous thick-walled cylindrical pressure vessels.... Read More about Effect of heat flux on creep stresses of thick-walled cylindrical pressure vessels.

The effect of septic tank locations on borehole water quality in Port Harcourt, Nigeria (2014)
Journal Article

The effect of septic tank locations on borehole water quality in five locations in Port Harcourt metropolis of Rivers State, Nigeria, was investigated. The locations were Miles I and III, Old GRA, Rukpokwu and Ada George. Three boreholes and septic t...

Application of a conditional approach for multivariate extreme values to flood risk (2014)
Presentation / Conference Contribution

Flood risk is a function of probability and consequence. Flooding events can arise from different sources, pluvial, fluvial, groundwater and coastal flooding. Sometimes flooding at a specific location arises from a single source in isolation. Often h... Read More about Application of a conditional approach for multivariate extreme values to flood risk.

A novel cutting strategy for measuring two components of residual stresses using slitting method (2014)
Journal Article

An exact knowledge of residual stresses that exist within the engineering components is essential to maintain the structural integrity. All mechanical strain relief (MSR) techniques to measure residual stresses rely on removing a section of material...

A novel method to determine material properties and residual stresses simultaneously using spherical indentation (2014)
Journal Article

Spherical indentation is one of the non-destructive techniques that has gained great interest among researchers in recent years. Spherical indentation is inexpensive and quick and can provide a fairly accurate estimation of in-plane residual stresses...

Neural network-based motion control of an underactuated wheeled inverted pendulum model (2014)
Journal Article

In this paper, automatic motion control is investigated for one of wheeled inverted pendulum (WIP) models, which have been widely applied for modeling of a large range of two wheeled modern vehicles. First, the underactuated WIP model is decomposed i... Read More about Neural network-based motion control of an underactuated wheeled inverted pendulum model.

Measurement and time dispersion analysis of UWB channels for Infostation application in an outdoor recreation park (2014)
Presentation / Conference Contribution

In this paper the time dispersive analysis of a set of data obtained from the UWB channel measurement of an environment typical of the Infostation scenario in a recreation park is presented. The measurements were carried out in the frequency band of... Read More about Measurement and time dispersion analysis of UWB channels for Infostation application in an outdoor recreation park.
