Ocean wave energy – An option for Nigerian power situation

As energy presents itself in various forms, here we will be looking at it from the perspective of wave energy. This paper investigates wave theory and use of some forms of mechanical wave fronts to generate electrical energy. A major means of production of these waves is discussed - being the wave front from the ocean, which is presently a source of worry to the people of Lagos State, Nigeria. These wave fronts from the...

Improved (G’/G)- expansion method for constructing exact traveling wave solutions for a nonlinear PDE of nanobiosciences

In the present paper, the improved (G’/G) - expansion method combined with suitable transformations is used to construct many exact solutions involving parameters of a nonlinear equation describing the nano-ionic currents along microtublues. As a result, hyperbolic function solutions, trigonometric function solutions and rational function solutions with parameters are obtained. When these parameters are taken...

Impact of computer graphics on the engineering product design: Conceptual analysis

Computer graphics matured over many years and played an important role in the development of engineering products like automotive and aircraft components. The current CAX (CAD/CAM/CAE) tools use computer graphics extensively, while helping in conceiving better designs with improved quality. Nowadays, engineering product development is being done concurrently and collaboratively, due to the advances in computer graphics....

Diagnosis and recommendation integrated system (DRIS) model establishment for diagnosing Sorghum (Sorghum bicolor) nutrient status in Benin (West Africa)

The Diagnosis and Recommendation Integrated System (DRIS) is a potential method for interpreting plant foliar nutrient composition. It provides a reliable means of linking leaf nutrient concentrations to the yield of sorghum, and has been developed for this crop using experimental data from organic and inorganic trials carried out in the Upper Catchment of Benin. Grain yield and leaf nutrient concentration were used to...

An inverse feedback fuzzy state space modeling (FFSSM) for insulin-glucose regulatory system in humans

The complexity and nonlinearity of the insulin-glucose regulatory system in humans demands for an inverse modeling technique. In this study the insulin-glucose regulatory system was modeled with the help of an inverse feedback fuzzy state space modeling (FFSSM) approach. The feedback insulin regulatory system was presented as a state space model, its input/output parameters fuzzified and the optimized values...

A robust digital watermarking technique based on feature and transform method

This paper proposed a new robust digital watermarking technique with an aim of image protection. The proposed technique incorporates both the transform and feature methods. Initially, the Harris Laplacian detector extracts the features from the cover image that suites well for the watermarking. The extracted characteristic regions are grouped to form a primary feature set where the secret message is embedded to form a...

Aircraft noise pollution assessment of Port Harcourt International Airport, Omagwa, Rivers State, Nigeria

An expressive survey, measurement and analysis of aircraft noise pollution assessment at the Port Harcourt International Airport, Omagwa, Rivers State, Nigeria has been performed. The study collaborated both sound levels and environmental pollution of aircrafts noise impact on the communities. Physical/acoustic measurements of the airport were carried out through the use of a BK Precision digital sound level meter....
