  In this study, we apply different software complexity measures to Quick sort algorithm. Our intention is to study what kind of new information about the algorithm the complexity measures (Halstead’s volume and Cyclomatic number) are able to give and to study which software complexity measures are the most useful ones in algorithm comparison. The results explicitly show that Quick sort has the least Halstead’s Volume, Program Difficulty and Program Effort when programmed in Assembly language.

  A face recognition system is one of the most desirable biometric identification such as computerized access control, document control and database retrieval. Although, several researches have been done on face recognition, most (if not all) have made use of non-black faces or very few numbers of black faces in their experiments. This study presents results of experiments based on black African faces (with and without tribal marks) using the optimized Fisher Discriminant Analysis. In the experiment, different sizes of gray scale images were used for recognition performance accuracy of between 88 and 99% were obtained. Also, taking into consideration was the rate of identifying an image using the same number of images to test the face recognition system. While, a completely robust real-time face recognition system is still under heavy investigation and development, the implemented system serves as an extendable foundation for future research.

  In this research, we studied the flow of a reacting pressure/temperature dependent viscous fluid, when air or oxygen is introduced into a channel containing hydrocarbon, oxidation or combustion is induced, we study the heat transfer in the channel. The model leads to system of momentum and energy equation and the resulting non-linear differential equation is solved numerically, we showed that the momentum equation just like the energy equation has multiple solutions.

  We are concerned with the solution of the differential equations of the form:

where, = m/n, n 0. Equations of this type arise in the generalized viscoelastic constitutive equations and in fractional Brownian motion. Numerical methods for solution of Eq. (1) are well established, particularly for 0

  This study presents a reacting system where the thermal conductivity depends linearly on the temperature of the system. A numerical solution of the resultant energy equation of the system is obtained using shooting technique with second order Runge-Kutta scheme. We show that maximum temperature decreases as thermal conductivity increases and also, the temperature of the system increases as the reaction parameter increases.

  We present a new generalized Mathematical model for the study of diabetes mellitus. The model takes into account all glucose intake and insulin injected (administered) as a function of the molecular weight of carbohydrate and protein intake, respectively. We also used the model to monitor the blood plasma glucose level in non-diabetic and suspected diabetic subjects. The results obtained were compared with results in literature graphically.

  This study studies the effect of activation energies and strong viscous dissipation term on two-step Arrhenius combustion reactions to give further insight into the theory of combustion under physical reasonable assumptions. We extend the non-uniformity of vessels discussed in Olanrewaju. It is shown, as in one step reaction that in a non-uniform vessel, maximum temperature occurs toward the end of the tube. On the other hand, in a uniform tube maximum temperature occurs at the centre. Also maximum temperature for diverging or converging channel is greater than that of a uniform vessel. The graph shows effect of viscous dissipation term on the temperature of the system.

  Controlling the spreads of the disease is a primary goal of health administrators. In this study, we examine a mathematical model of virus neutralizing antibody response using a stability of the model based on Perron theorem. It is shown that the spread of the disease can be controlled if the critical parameter , where B* is the scale initial value of B cells and 6 is the death rate of the free virus.

  We study a two-step Arrhenius reaction in the multiple-step reaction that occurs during decomposition and combustion processes of a precursor chemical reagent. In order to enhance safety during manufacturing, storage and handling of the energetic materials, we revisit and analyze the equilibrium, stability and Hopfs bifurcation of the two-variable model for combustion in sealed containers and investigate the effect of reaction order on stability of the equilibrium solution. The numerical result of Hopfs bifurcation condition shows that the region of instability increases as the reaction order increases.
