    » A Proposed Method of Identifying Significant Effects in Unreplicated Factorial Experiments

    » Ibraheem B. A., Adeleke B. L. and Oyeyemi G. M.

    ABSTRACT:

    In many areas of research/ production, a lot of factors are combined to obtain a desired product. To be able to analyze which factors (or combinations of factors and at what level) are significant, the experiment has to be replicated. For economic or practical reasons, it may not be feasible to perform the experiment more than once therefore unreplicated factorial designs are often employed. This is especially true in the field of Medicine, Pharmacy and Industrial production units. The traditional method of analysis of variance (ANOVA) cannot be employed in unreplicated factorial designs, therefore many methods have been proposed in literature. In this paper, a new method of analyzing unreplicated factorial designs is proposed and was compared with some of the existing methods. The four existing methods considered were: Lenth, Berk and Picard, Juan and Pena, and Dong. The comparison was performed using Monte Carlo simulation method. The criteria used in evaluating the performances of the methods are Power and Individual Error Rate (IER). Using these criteria of evaluation, the results showed that on overall performance, Dong method is the best among the four existing methods considered and was closely followed by Berk and Picard, Lenth, then Juan and Pena methods in that order. It was also found that not only is the proposed method simpler to compute, it competed favourably with Dong and even performed better than all the others when IER is used for assessment.

    » Performance Enhancement of Huffman Coding Image Compression with Chinese Remainder Theorem

    » Mohammed Babatunde Ibrahim and Kazeem Alagbe Gbolagade

    ABSTRACT:

    Data compression is the process of reducing the size of data. Due to the improvement of Information Technology, there are more data that are being generated nowadays that are transferred from one source to another. This data required higher size and bandwidth to be transferred between two parties. Hence, how to reduce the size of data before transferring from one medium to another has been an important issue. This paper proposed an enhanced method to compress image data file. In this paper, we integrate Chinese Remainder Theorem (CRT) into the Huffman compression algorithm to enhance the speed of compression as against the Traditional Huffman Compression (THC). The experimental analysis was performed in matrix laboratory environment (2015). The experimental results revealed that there is significant reduction in size of image, compression time minimization and data quality retention of original image. The shortcomings of THC are blocky appearance and poor quality reconstructed image after decompressing operation is overcome in our enhanced method with CRT.

    » K.Sreekala and K. Sai Jeevan Reddy

    ABSTRACT:

    The Main Objective of Transport Location Inference Drawing Using Global Positioning System is to help the passengers to track the location of their respective vehicle. Nowadays, it became difficult for passengers to know the exact location of the vehicle for which they are waiting. This application helps the passenger in tracking the vehicle and reach to the boarding point on time. Passengers can greatly use this application since Android mobiles have become common and affordable to all. This will also enhance security since the movement of the vehicles is always available. It is a real-time system as the current location of the bus is updated every moment in the form of latitude and longitude which is received by the passengers through their application on Google maps.

    » Development of a mobile application for swazi entertainment events

    » Mashwama Petros, Fashoto Stephen G. and Mabuza Lindelwa

    ABSTRACT:

    The use of mobile technology within the entertainment industry is growing at a fast rate worldwide. In Swaziland, the lack of real time informative platforms has led to several property damages due to an angry audience that did not get all the information or updates about an event on time. This paper presents a system that connects event organizers, artists, and fans. It has been noted that most event mobile applications tend to focus on either uploading information on events updates or information on artists. This system integrates these two ideas into one package in the sense that users have event updates and also get updates on a specific artist all in the same system. Most of the existing applications do not have a platform where users get to comment about a past event that was uploaded in a system.

    » Spotting Skin Disorder using Template Matching

    » K. Sreekala and K. Sree Mounika

    ABSTRACT:

    There are a number of skin diseases like Acne, Eczema, Hives, impetigo, Melanoma, Moles etc. Acne is a disease that affects the skin's oil glands. The small holes in the skin (pores) connect to oil glands under the skin. These glands make a substance called sebum. Eczema, also known as atopic dermatitis, is a long-term skin disease. The most common symptoms are dry and itchy skin, rashes on the face. Hives causes red and sometimes itchy bumps on the skin. Likewise, different skin diseases have different symptoms. Sometimes, it is difficult for the dermatologist to diagnose the skin disease by looking at the disease. This paper aims at spotting the skin disorder by using the template matching algorithm.

    » Comparative Analysis of Some Selected Metaheuristic Algorithms for Solving Intelligent Path Planning Problem of Mobile Agents

    » Olabode A. O., Abdulkareem B. Q. and Ajao T. A.

    ABSTRACT:

    Mobile Agents (MA) are objects that migrate through the nodes of heterogenous networks to perform intelligent path finding tasks. Prioritizing the metaheuristics algorithms (PSO, ACO, GA and SA) with the best performance in terms of cost value and computational time efficiency for mobile agents path planning has been a major challenge. The performance of these selected meteheuristic algorithms was evaluated. Prototypes of mobile agents were introduced into two dimensional (2-D) workspace of adhoc network consisting of 16 nodes. The PSO, ACO, GA and SA were introduced into the mobile workspace for path planning and encoding. The corresponding path plans from PSO, ACO, GA and SA were later used for finding path and implemented in MATLAB environment. The performance of the metaheuristic techniques was evaluated using Computational Time (CT), Cost Value (CV), Program Effort (PE) and Program Size (PS).

    » Effect of Computation Time, Memory usage and Number of Nodes visited on the Performance of Some Selected Heuristic Algorithms

    » Olabode A. O. and Fenwa O. D.

    ABSTRACT:

    The efficiency with which searching is carried out often has significant impact on the overall efficiency of a program. Some of the factors affecting the performance of informed tree based or heuristic search algorithms include high exponential execution time to search, drastic memory or storage usage and number of nodes visited. However, prioritizing each of these factors based on their influence has been a major challenge. Therefore, this research prioritized computational time, memory usage and number of nodes visited based on their influence using factor analysis by principal component.

    » Split-Plot Analysis to Investigate Different Rates of NPK Fertilizers application and Genotype on the Yield of Cassava

    » Osuolale Peter Popoola, Matthew T. Odusina, Ayaniyi A. Ayanrinde and Abosede T. Popoola

    ABSTRACT:

    Cassava (Manihot esculenta Crantz) like any other crops required high soil nutrients content for quality and quantity yield. When the crop is grown on the land for a number of years in succession or in rotation, the stored nutrients in the soil will be reduced and must therefore be replenished by means of fertilization. This depletion of nutrients is aggravated when a high-yielding cassava variety is planted. Hence, this study investigates to know if NPK fertilizers and genotype have effect on the yield of Cassava, examines at what proportion the trio of Nitrogen, Phosphorus and Potassium are to be applied and which genotype is the best and what would be the optimum yield when NPK is applied correctly to the best genotype. A Split – plot design was adopted in the data analysis. Further test was carried out using LSD, Tukey, Scheffe and Bonferroni to detect which of the levels of NPK fertilizer and Genotype have significance effect on the yield. Multiple regression model was obtained to investigate at what proportion the trio of Nitrogen, Phosphorus and Potassium are to be applied, Response surface methodology was carried out to obtain the optimum yield of Cassava. The result of the Analysis of Variance (ANOVA) carried out showed that NPK Fertilizer and Genotype contribute significantly to the yield of Cassava. A further analysis on the Mean Separation of the Fertilizers at various levels of application and different Genotype shows that fertilizer when applied at N0P50K150 are more significant than any other levels, Genotype B is the best and the best variety is C. Thus, the multiple regression model for Cassava was obtain as Yield=131.5805+4.6462B–4.6462G+4.5803F–0.2127B*G– 0.0179 B*F+0.1140*G*F. Hence, the fixed regression model showed that optimum yield of 181.902 tone / hectare is achievable if NPK fertilizers are applied appropriately at the recommended rate.

    » Modification of Ratio Estimator for Population Mean

    » J.O. Muili and A. Audu

    ABSTRACT:

    In this study a ratio type estimator of finite population mean has been proposed under simple random sampling without replacement. The properties of the proposed estimator (Bias and Mean Square Error) have been obtained up to first order of approximation using Taylor’s Series Expansion and the condition for its efficiency over some existing estimators have been established. The minimum value of the mean square error of the proposed estimator has also been derived. The efficiency of proposed estimator based on optimal value of the constant, exhibit significant improvement over the existing estimators considered in the study. Empirical studies were conducted with natural populations to demonstrate the performance of the proposed estimator comparing with some existing estimators. The results of the empirical study show that the proposed estimator performs better than the existing estimators.

    ABSTRACT:

    Assessment of the view of senior school students on HIV/AIDS was carried out in Offa Local Government Area of Kwara State, Nigeria with the aim of investigating the general views of senior school students on HIV/AIDS. Random sampling technique was employed to select 10 schools comprising both public and private schools while purposive method was used to sample 300 biology students across the selected schools. Sharing of blade, needle or any sharp object with another person had higher risk of contracting HIV account for 89.3% of the respondents, followed by casual sex intercourse with an infected person and prostitutes. It is therefore recommended that HIV/AIDS and sex education should be incorporated into the Biology curriculum of senior secondary school students in Nigeria. Also, more emphasis should be made on abstaining from early sexual activities and parents should be encouraged to talk about sex values to their children.

    ABSTRACT:

    Tuberculosis has persisted over the years as a significant contributor to mortality and morbidity counts globally and in particular, Nigeria. This study formulated a continuous-time Markov process model for TB dynamics with the introduction of vaccination impact in the susceptible and exposed classes. Using the Gillespie’s algorithm, we obtained stochastic realizations of the disease behavior using the Kolmogorov equations. Sensitivity analysis on impact of key parameters showed that intervention effort at 50% - 85% effectively reduced TB incidence despite reinfection of recovered individuals.

    » Investigation of Family Planning as a Function of Women Lifespan using a Multiple Regression Approach

    » Marufat B. Oyedeji

    ABSTRACT:

    The focus of this study was to examine the effect of family planning based on the methods of contraceptives on women life span (female life expectancy), using the secondary data collected from the University College Hospital (UCH), Ibadan, Lagos Bureau of Statistics (LBS) and World Bank Statistical database. Analytically, regression model was employed in this study. The data, being a time series data was tested for stationarity using the augmented Dickey- Fuller test and the test indicates that the data were stationary. The results obtained indicate that the method of contraceptives and age are statistically significant for predicting women life span. The coefficient of determination in the regression output also revealed that 93.37% (0.9337) of the total variation in life expectancy was accounted for by the use of contraceptive (injectable, Oral, pills and IUCD) and age with other variables in the expectancy. This study concludes that that the independent variables explain the dependent variable substantially and recommends the need to provide aggressively family planning education, so that people can understand the use, cope with it, take control and develop survival skills. The analyses were done in Minitab and E-views statistical packages to estimate the parameters of the model.

    » A Neural Network Approach in Performing Non-Invasive Analysis of Muscle Impulses for Hand Gesture Recognition

    » Akinrotimi, Akinyemi Omololu and Mabayoje, Modinat Abolore

    ABSTRACT:

    Surface Electromyography (sEMG) signals have been found to be useful in developing methods of recognizing hand gestures using digital signal processing devices or ensemble approaches. In building hand gesture recognition models, it is essential to avoid or reduce computational complications which may result in complex circuit connections while implementing the model. As such, simple but efficient approaches in achieving the desired results are required. A explicable model for hand gesture recognition, using Flexible Neural Trees (FNTs) and sEMG signals is presented in this paper. sEMG is an approach of detecting and documenting the electrical impulses of the muscles, from the surface of the skin. The feed forward Neural Network approach is first used in generating the FNT model before improving it, using predefined simple instruction sets. The FNT model helped to avoid complex computations while building the model and provided a high recognition rate. The experimental outcomes obtained from the developed model shows that the model is capable of classifying six different hand gestures at an accuracy of 92.46%.

    ABSTRACT:

    This study evaluated the effect of atmospheric condition on radio network. Response Surface Methodology was used to develop a signal model in terms of atmospheric condition, analyse and optimize the effect of atmospheric temperature, pressure and relative humidity on signal of a WE-FM radio station based in Abuja. The result shows that atmospheric parameters such as temperature, pressure and relative humidity have inverse relationship with radio signal. The analysis of variance for the model formulated reveals that the atmospheric parameters have significant effect on signal strength. Also, the R – Squared value obtained implies that atmospheric condition have variability of 98.30% on the signal strength. The optimum signal strength of 54.0851 dBuV was obtained with the atmospheric condition of temperature 26.800C, pressure, 24.43inHg, and relative humidity of 78%. The model predicts signal strength with the accuracy of 84.71%. Hence, the approach is efficient for minimizing signal strength degradation in radio network.

    » Efficiency of some Modified Ratio Type Estimators using product of Sample size and parameters of auxiliary variable for estimating Population Mean

    » S. A. Suleiman and A. A. Adewara

    ABSTRACT:

    In this paper, we modified twenty-eight ratio type estimators for estimation of population mean of the study variable earlier suggested by Gupta and Yadav (2017) using product of sample size and population parameter of auxiliary variable. The expressions for the bias and mean square errors of the newly modified ratio type estimators have been obtained up to the first order of approximation. A comparison has been made with the mentioned existing ratio estimators of population mean using the same data set used by Gupta and Yadav for easy justification. The results obtained on the Mean Square Errors shows that the newly modified ratio type estimators perform better vis-à-vis the earlier suggested Gupta and Yadav existing ratio type estimators but the newly modified ratio type Estimator, t*27, perform better, hence, recommended for usage in Sampling.

    » Develop Self-Studying Ability of High School Students through Learning Projects - A Case Study in Vietnam

    » Nguyen Van Quyen

    ABSTRACT:

    In addition to traditional teaching methods, project-based teaching method has been introduced to catch up with the modern trend in education in the world towards improving students' self-learning capacity. By understanding the principles of project-based teaching teachers will have more opportunities to promote the self-learning of students, thereby making teaching activities more plentiful and practical. Therefore, in this research I aim to enhance the capacity of Mathematics self-studying of high school students through learning projects. This research was done through studying documents related to capacity and Mathematics self-study ability. In addition, in order to evaluate the results of mathematics self-study capacity of high school students in Vietnam I and the teachers involved in the project designed the assessment tool set including self-studying ladder levels, and a self-assessment note. Fourteen 10-grade students were randomly selected to participate in the project. Research results: The learning project has improved the efficiency, confidence and interest of students in solving practical problems, nurturing creative talents. Students increase their self-study ability. In addition, this study is the basis for teachers, educational researchers and curriculum developers to implement a constructive approach in enabling students to understand the relationship between theory and practice, then improving students' self-studying ability.

    KEYWORDS:

    Project -based teaching, self-studying ability, solving practical problems.

    » Improved Modified Ratio Estimator for Estimating Population Mean in Double Sampling Using Information on Auxiliary Attribute

    » F. E. Amoyedo and A. A. Adewara

    ABSTRACT:

    This paper proposes a modified family of ratio estimator of population mean using information on auxiliary attribute and the estimation of population mean in double sampling in ratio form. The proposed modified ratio estimator is a family of estimator which results to different estimators at different value of alpha. For the proposed estimator, when α = 0,0.5 and 1, the estimators of Naik, Gupta, Nirmala Sawan and Sample mean were recovered respectively. When the auxiliary attribute is a variable, the estimator result to that of Subhash et al. When α=0 and the auxiliary attribute is a variable, it results to conventional double sampling. The expression for the Bias, and Mean Square Error of the proposed modified estimator were obtained up to the first order of approximation. An efficiency comparison of both the theoretical and empirical were carried out with some related existing estimators in double sampling. It has been established that the proposed modified ratio estimator is more efficient when compared with the existing ones at optimum value of alpha.

    KEYWORDS:

    Ratio estimator, bias, mean square error and double sampling.

    » Robust Three-step Broyden-like Algorithms for Functions of Several Variables

    » S. O. Yusuff, I. A. Osinuga, O. J. Adeniran and S. A. Onashoga

    ABSTRACT:

    In this work, we suggest some variants of Broyden-like algorithm to solve systems of nonlinear equations using various combination of quadrature rules . The proposed methods are three-step in nature whereby the first step is the initial iterate of the Newton’s method and the remaining two steps are the predictor-corrector of Broyden method and quadrature rules. Numerical tests show that these methods give encouraging results with respect to some existing Broyden-like methods in view of Dolan and More performance profile and Bogle and Perkins comparison index.

    KEYWORDS:

    Broyden-like method, quadrature formulas, predictor- corrector model, systems of nonlinear equations, numerical examples.

    » Exponential Smoothing Methods in Forecasting Nigeria Consumer Price Index

    » K. A. Muhammed, F. A. Bolariwa and I. O. Ajao

    ABSTRACT:

    The consumer price index (CPI) measure the average change over a time in price of goods and services consumed by people, this study is focus to determine the best smoothing technique, to remove the irregularity in the series and to use the smoothed data to fit the model for future prediction. The data used for this study are monthly data, extracted from the record of CBN via www.cbn .gov.ng. The data spanned from January 1995 to December 2017. The behavioral pattern of the associated time plot exhibits the existence of trend and non-seasonality in the data. In view of this, non-seasonal Exponential Smoothing Techniques were adopted and the Holt’s Smoothing Exponential Technique was proved to be the best techniques to use for this study because, the accuracy measure i.e. MAPE (2.457), MAE (0.9352), MSE (4.5512), are relatively smallest compare with others used smoothing techniques, using the smoothing constant α( 0.933) and β(0.07) The future value of Nigeria CPI for year 2018 was predicted using fitted equation. In view of this study, it was discovered that Nigeria CPI will be gradually increasing over times.
