    Analysis of convective-radiative porous fin With temperature-dependent internal heat Generation and magnetic field using Homotopy Perturbation
    (Journal of Computational and Applied Mechanics, 2017) Sobamowo, M.G; Adeleye, O.A; Yinusa, A
    In this work, thermal behavior of convective-radiative porous fin with temperature-dependent internal heat generation subjected to magnetic field using homotopy perturbation method is analyzed. The developed symbolic heat transfer model is used to investigate the effects of convective, radiative, magnetic parameters on the thermal performance of the porous fin. From the study, it is established that increase in porosity, convective, radiative and magnetic parameters increase the rate of heat transfer from the fin and consequently, improve the efficiency of the fin. The homotopy perturbation method used in the work is validated with the results of a numerical method. The results of the two methods are in excellent agreement. Therefore, this study provides a platform for comparison of results of any other method of analysis of the problem. Also, such an analytical tool is valuable as a design and optimization approach for finned heat exchangers where each fin/row is analytically analyzed and where the surrounding fluid is influenced by a magnetic field.

    Application of Daftardar-Gejiji and Jafari Method to Kinetic Analysis of Thermal Inactivation of Jack Bean Urease
    (Journal of Applied Mathematics and Computational Mechanics, 2018) Sobamowo, M.G; Adeleye, O.A
    Jack bean urease has been used as a good catalyst for hydrolysis of urea in various applications such as biotechnology and biomedical engineering. The wide range of applications require proper understanding of the thermal inactivation of the enzyme. Consequently, the theoretical analysis of the enzyme kinetic of the thermal inactivation is required. In this paper, a new iterative method proposed by Daftardar-Gejiji and the Jafari method is applied to analyse the kinetic of thermal inactivation of jack bean urease (EC3.5.1.5). The kinetics of the urease consist of three-reaction steps and included the Arrhenius equation for temperature-dependent rate constants as well as the temperature change in the initial heating period. The approximate analytical solutions are verified with results of numerical method using Runge-Kutta with the shooting method, and good agreements are established between the results of the methods. From the analytical investigation, it is established that the molar concentration of the native enzyme decreases as the time increases while the molar concentration of the denatured enzyme increases as the time increases. The time taken to reach the maximum value of the molar concentration of the native enzyme is the same as the time taken to reach the minimum value of the molar concentration of the denature enzyme. It is hoped that the information given in this theoretical investigation will assist in the kinetic analysis of thermal inactivation of the experimental results over handling rate constants and molar concentrations.

    (UNILAG Journal of Medicine, Science and Technology, 2016) Adeleye, O.A; Fakinlede, O.A; Ajiboye, J.S; Adegbulugbe, C.I
    The deformation behavior of commercial microhybrid resin based composite (20/20 composite) and nanofilled composite (Light Cured Universal Composite) cured with the conventional Light Emitting Diode (LED) and exponential Light Emitting Diode (HiLED) under various loading condition have been investigated. Deformation of restorations such as shrinkage and shearing from curing and mastication have been a major concern for clinicians because of void and crack formations in restored tooth structure which affects the mechanical properties of the resin composites. Samples of microhybrid resin based composite (20/20 composite) and nanofilled composite (Light Cured Universal Composite) were molded with copper foil molds with standard dimension 2 x 2.5 x 8mm, photo-cured by both conventional Light Emitting Diode (LED) and exponential Light Emitting Diode (HiLED) and then tested on the ElectroForce 3200 for their deformation behavior and mechanical properties. Effects of variation of strain rate and curing time were also investigated. The results showed that, out of the four groups of samples studied, microhybrid resin based composite (20/20 composite) cured with exponential Light Emitting Diode (HiLED) exhibited highest tensile strength of 28 MPa. The loading and unloading of the samples exhibited hysteresis responses and path dependence nonlinear behavior. At stress values less than 4 MPa, rate dependent recoverable (viscoelasticity) deformation was observed in all the four groups of samples but at stress values beyond 4 MPa rate dependent irrecoverable (viscoplasticity) deformation was observed. Finally, it was observed that increasing curing time leads to increasing tensile strength for materials cured by both methods.

    (Faculty of Engineering, The University of the West Indies St Augustine, Trinidad and Tobago, West Indies, 2019-07-01) Nwaneri, S.C; Ogbuji, P.I
    Cardiovascular diseases are the most common causes of deaths globally. Continuous and regular monitoring of vital signs is necessary for patients suffering from cardiovascular diseases especially in low and middle income countries (LMIC), with limited facilities for diagnosis and monitoring of the cardiovascular system. In this paper, a low cost, non-invasive cardiovascular monitoring system was developed. The system was powered by a 12V battery and consists of a pulse rate sensor for recording pulse rate, heart monitor sensor for recording electrocardiogram, Arduino board (ATMega 2560), potentiometer, jumper connecting wires, 16×2 liquid crystal display monitor. The design includes modulation and demodulation sections that record signals from the measure and and transmit them to the doctor. The device was initially tested on ten subjects. Periodic heart beat was observed with mean ± standard deviation pulse rates obtained as 75.82 ± 1.09 BPM (beats per minute). Further comparison between the device and a standard blood pressure monitor on forty-five volunteers revealed a mean pulse rate of 76.44 ± 10.04 BPM and 77.84 ± 10.65 BPM for the proposed and standard device, respectively. The Wilcoxon-signed rank test results performed in SPSS gave a p-value of 0.118, showing that there was no statistically significant difference between the pulse rates observed in both devices. Standard Electrocardiograph (ECG) waveform for healthy subjects was obtained when the device was tested on healthy patients. Based on the test results, the device was shown to be effective for real-time monitoring of the cardiovascular system.

    Developing Sustainable Renewable Energy for Rural Dwellers' Energy Sufficiency
    (ABUAD Journal of Engineering Research and Development (AJERD), 2017) Ajibola, O.O; Ibidapo-Obe, O; Balogun, O.J
    The issues connected with the worldwide growth in energy consumption, energy conservation, and finding environmentally benign ways of energy production may arguably be the most significant challenge facing mankind in the 21st century. Government policies on rewarding economic goals have failed due to inadequate supply of energy. A strong energy sector is essential for a vibrant and competitive economy. Whilst we proceed with increasing the energy generation capacity, transmission and distribution of existing energy from traditional sources through the development of energy systems that enhance social, economic and environmental performance; it is appropriate to focus on renewable and sustainable energy forms for rural areas. In this paper, we explored various renewable and sustainable energy options, namely: solar, wind, micro hydro, fuel cells and bio fuel; with the aim of proposing an environmental friendly and cost effective option that will ultimately solve the energy crisis both in rural and urban areas in Nigeria. Our methodology is purely empirical with data drawn from a pilot project carried out on a household in Magboro community, a suburb of Lagos. The result of the work revealed that the solar system based on photovoltaic cells is a viable renewable energy solution to the perennial power failure especially to the rural populace in Nigeria. The ultimate aim of this paper is to provide the springboard for the development of an enduring energy policy in Nigeria.

    (Korean Society of Medical Informatics, 2022-01) Odukoya, O.; Nwaneri, S.; Odeniyi, I.; Akodu, B.; Oluwole, E.; Olorunfemi, G.; Popoola, O.; Osuntoki, A.
    Objectives This study developed and compared the performance of three widely used predictive models—logistic regression (LR), artificial neural network (ANN), and decision tree (DT)—to predict diabetes mellitus using the socio-demographic, lifestyle, and physical attributes of a population of Nigerians. Methods We developed three predictive models using 10 input variables. Data preprocessing steps included the removal of missing values and outliers, min-max normalization, and feature extraction using principal component analysis. Data training and validation were accomplished using 10-fold cross-validation. Accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the receiver operating characteristic curve (AUROC) were used as performance evaluation metrics. Analysis and model development were performed in R version 3.6.1. Results The mean age of the participants was 50.52 ± 16.14 years. The classification accuracy, sensitivity, specificity, PPV, and NPV for LR were, respectively, 81.31%, 84.32%, 77.24%, 72.75%, and 82.49%. Those for ANN were 98.64%, 98.37%, 99.00%, 98.61%, and 98.83%, and those for DT were 99.05%, 99.76%, 98.08%, 98.77%, and 99.82%, respectively. The best-performing and poorest-performing classifiers were DT and LR, with 99.05% and 81.31% accuracy, respectively. Similarly, the DT algorithm achieved the best AUC value (0.992) compared to ANN (0.976) and LR (0.892). Conclusions Our study demonstrated that DT, LR, and ANN models can be used effectively for the prediction of diabetes mellitus in the Nigerian population based on certain risk factors. An overall comparative analysis of the models showed that the DT model performed better than LR and ANN.

    (Unilag Journal of Medicine, Science and Technology (UJMST), 2017-06-01) Nwoye, E. O.; Odebiyi, D. O.; Aiyegbusi, A. I.; Bakare, A. D.
    Introduction: Deep tendon reflex (DTR) is routinely used to evaluate the nervous system. Majority of the available devices to measure DTR response are not easily accessible, highly cumbersome, and capital intensive. This study sought to develop and evaluate a less cumbersome, cost effective and easily accessible instrument that can objectively quantify DTR Material and Methods: A simple DTR deice was fabricated and then evaluated. A total of 74apparently healthy individuals and five hemiplegic patients participated in this cross-sectional analytical study. Hemiplegic participants were to determine the criterion-related validity of the device. Of the apparently healthy participants, 69 were assigned into three groups according to their age. Angle of knee excursion (patellar \DTR response) was measured using the newly d3eveloped DTR device. Jendrassick maneuver was introduced in participants who failed to response to the initial patellar tendon tapping. Pearson correlation was used to determine relationship between variable at P < 0.05 Result: The device demonstrated good face and criterion-related validity coupled with high rest-retest and inter-rater reliability with coefficient of 0.74 and 0.86 respectively. There was no significant difference between the patellar tendon response for the right and left lower limbs (p>0.05. similarly, sex and age has no significant effect on the patellar tendon reflex response respectively (p>0.05 Conclusion: the newly developed instrument is less expensive and less cumbersome and was found to be valid. Findings of the study are comparable with previous study that age, sex and handedness had no significant effects on DTR response. It is therefore recommended for the use of clinicians.

    (Nigerian Journal of Technology (NIJOTECH), 2018-01-01) Nwoye, E. O.; Fidelis, O. P.; Falola, A. O.; Odebiyi, D. O.
    Exercise bicycles are used for kinesiological activities; to increased general fitness, and for training for cycling events. They are also used for weight loss. The aim of this study is to produce a special exercise bike which allows for both upper and lower limbs pedaling either independently or otherwise. The manufacturing processes employed in the design involved the use of AutoCAD design suite and other production engineering processes which included material selection and acquisition, cutting, welding and drilling. This device was tested for both comp=fort and effectiveness for cardiac rehabilitation using the rate of heartbeat as the test parameter. A strong positive correlation was found (p<0.001; =0.962) between the two heart rate tests. An ergonomic evaluation of the bi-modal exercise bike showed 98% suitable of the seat-pedal height with the knee height of the study population and 100% suitable of the seat handle post height with the buttock-knee length of the population. In conclusion, the goal of developing a bi-modal exercise bike that permits simultaneous upper and lower limbs pedaling was realized.

    Development of Exact Analytical Solution for Nonlinear Heat transfer Equation of Natural Convection Porous Fin
    (Journal of Engineering Research, 2016) Sobamowo, M.G; Adeleye, O.A
    The present of nonlinear term in heat transfer models makes it very difficult to develop exact analytical solutions to the problem. Consequently, recourse has been made to numerical or approximate analytical methods. However, the classical way for finding exact analytical solution is obviously still very important since it serves as an accurate benchmark for numerical and approximate analytical solutions. Therefore, in this work, exact analytical solution is developed using Gauss’ hypergeometric function for the nonlinear equation arising during heat transfer in porous fin. The developed model was validated with numerical method of solutions and the results were in good agreement. The developed exact analytical model can be compared with other approximate analytical methods found in the literature which are used for solving similar problems.

    Dynamic Analysis of the Biomechanical Model of Head Load Impact Using Differential Transform Method
    (Journal of Applied and Computational Mechanics JACM,, 2019) Adeleye, O.A; Ipinnimo, O; Yinusa, A.A; Otobo, E.P
    The dynamic analysis of the biomechanical model of the head load impact using the Differential Transform Method is presented in this paper. In many parts of the world, the problem of traumatic brain injuries (TBI) has led to neurodegenerative dementing disorders and diseases as a result of head load impact from sporting activities, accidents involving the head, etc. have serious effects on humanity. The head load impact and its control have been modeled as a rigid linkage head-neck manipulator. This rigid link manipulator is governed by a system of nonlinear ordinary differential matrix equations with three degrees of freedom which requires special techniques for its solution. The system of equations was solved using Differential Transform Method (DTM) and the results were compared with results obtained in earlier studies and validated with the fourth-order Runge-Kutta numerical method (RK4). Good agreements are reached in all these results. From the model, the effects of head loads, head mass, neck mass, upper and lower linkage lengths, head and neck moments of inertia were investigated. As the head loads increased, there were increases in both axial and angular displacement of the head motion and the neck region. The study provides a theoretical basis for the design and understanding of the effects of head load carriage on vital organs that are susceptible to pains, damages, and even failure.
