    » Handling Multicollinearity; A Comparative Study Of The Prediction Performance Of Some Methods Based On Some Probabiltiy Distributions

    » Zakari Y., Yau S. A. and Usman U.

    ABSTRACT:

    This study used some probability distribution (Gamma, Beta and Chi-square distributions) to assess the performance of partial least square regression (PLSR), ridge regression (RR) and LASSO regression (LR) methods. Ordinary Least Squares may fail if the variables are almost collinear or related. As such, this methods (PLSR, RR, AND LR) were compared using simulated data that follows gamma, beta and chi-square distributions with number variables (P=4 and 10) and sample sizes (n=60 and 90). The comparison was carried out using Mean Square Log Error (MSLE), Mean Absolute Error (MAE) and R-Square (R2) which shows that the results of RR is better when P=4 and n=60 using gamma distribution, but using chi square distribution PLRS is better methods. Also, when P=4 and n=90, RR shows better results with both gamma and beta distributions but with chi square distribution all methods have equal predictive ability. However, at P=10 and n=60 RR performed better with both gamma and chi square distributions while when data follows beta distribution all distributions have equal predictive ability. RR shows better results at both gamma and chi square distributions when P=10 and n=90 while PLSR performed better with beta distribution.

    » On the Estimation of Empty cell Probabilities in a Contingency Table

    » Oyeyemi, G. M. and Mbaeyi, G. C.

    ABSTRACT:

    In this paper, an Independent Binary Model (IBM) is proposed. It is aimed at estimating cell probabilities in an r x c contingency table when some of the cells have zero count. Existing methods in this situation are either subjective or based on arbitrary decision of the researcher. The IBM is applied to sets of simulated data for various combinations of categorical variables. It is pointed out that the IBM could be an alternative for such situations especially when the result is needed for further analysis.

    » e-HAMS: A Unified Model-based Integrated Healthcare Services Management System for Low-and-Middle Income Economies

    » Fagbola Temitayo Matthew, Egbetola Funmilola Ikeolu, Emuoyibofarhe Justice, Olaniyan Olatayo Moses, Oloyede Ayodele and Akinpelu James

    ABSTRACT:

    The emerging proliferation of fragmented healthcare applications has accounted for an overwhelming high cost of maintaining healthcare services and facilities, clinical data security and privacy concerns, decentralized data redundancy leading to snail-speed of improvement in healthcare services’ delivery efficiency and more often than not, a total shutdown of health facilities. Due to lack of communication among these decentralized and often similar health applications, their relative characteristics and advantages are either misaligned and/or duplicated in most cases. Hence, needs be that robust and integrated healthcare services management applications, that can collaboratively deliver consolidated healthcare objectives and facilitate huge cost savings, seamless clinical information workflow, optimum access and sharing of centralized clinical data, highly-efficient quality of service (QoS) and real-time accountability, be developed especially for the healthcare systems in low-and-middle-income economies. In this paper, an integrated web-based electronic HealthcAre Management System (e-HAMS) for low-and-middle income economies was developed. e-HAMs is a composite mobile-compliant system with a collaborative framework that accommodates electronic patients’ health record, electronic cash flow audit, electronic personnel record management, electronic pharmacy services and the electronic healthcare services payment management systems. Prior to its development, a users’ needs assessment was conducted and the possibility that e-HAMS would offer some cost-savings benefit was also modelled. The collaborative model when evaluated based on Closed World Assumption (CWA) reveals that cost-savings benefit is huge. An underlying architecture for the integrated development plan was also developed. Unified modeling language and V-shaped software development model were employed to co-design and orient the development of e-HAMS. Interactive graphical user interfaces were developed to implement e-HAMS’ designs in a visual studio integrated development environment using C# language. The system database was developed using a SQL server application. At the testing stage, a qualitative users’ assessment of e-HAMS was conducted to evaluate the performance of the developed e-HAMS system. Results obtained reveal that cost savings benefit of e-HAMS is rated at 96%, reliability (92%), availability (90%), privacy (90%), security (89%), quality assurance (86%), user interface design (82%), ease of use (78%) and user friendliness (76%) in that order. Thus, e-HAMS is best suited for low-and-middle income economies to realize improved Quality of healthcare services delivery and facilitated efficiency of operations while offering timely generation of informed decisions.

    » Performance Evaluation of Implementation Languages on Cognitive Complexity of Dijkstra Algorithm

    » Isah Olawale Mustapha, Stephen Olabiyisi, Rasheed Gbenga Jimoh and Maruf Olasunkanmi Alimi

    ABSTRACT:

    Maintainability is a key factor in measuring the quality of developed software and it becomes important due to dynamism of software. Partially, maintainability is a function of source code understandability on the part of developers. Therefore, cognitive complexity of software is relevant to its maintainability. In fact it is not an overemphasis to state that, quality of software in general can hardly be control if the code is complex (Banker, Datar and Zweig, 2009;francalanci and Merlo, 2010). Hence as a result of strong impact that cognitive complexity has on the software quality this research work investigates the effect of some implementation languages on cognitive complexity. Three earlier and recent implementation languages were sampled in term of Procedural Programming Languages and Object Oriented Languages then implemented on a unique algorithm and appraised using Procedural Cognitive Complexity Metric[P.C.C.M] and Multiparadigm Cognitive Complexity Metrics [ M.C.C.M] respectively. The experiment results have shown that among the procedural programming languages, Fortran has least cognitive complexity with sixty six while among Object Oriented Languages C++ has the least with one hundred and thirty eight. Cross assessment of Fortran and C++ using both [P.C.C.M] and [M.C.C.M] reveal that Fortran has the least cognitive complexity among all the implementation languages used. The research results has shown that Fortran 77 is the best for implementation of Dijkstra algorithm among the selected languages to have the least cognitive complexity and has reaffirmed that some languages are more appropriate for easy understandability of source code than others.

    » Quadratic Regression and Factorial Analysis on the Effect of Climatic Elements on Global Food Production and Land Nutrients in Africa

    » Osuolale Peter Popoola, Omotola Omotayo Dawodu and Olufemi Olusola Yusuf

    ABSTRACT:

    The United Nation has its number one Sustainable Development Goal (SDG #1) of No Poverty Global World which is, Agriculture and Food Security. The question to be asked is how do we make production of food like maize, rice, and wheat (the three – world stable food) available in abundant, in the face of excessive temperature, limited or excessive rainfall, and low or sometimes high humidity? World maize, rice, and wheat production must increase by approximately 1% annually to meet the growing demand for food that will result from population growth and economic development. Global mean surface air temperature increased by ≈0.5°C in the 20th century and is projected to further increase by 1.5°C to 4.5°C this century. The seasonal and spatial variation of temperature, rainfall and humidity have been an important climatic factor determining the cropping pattern, regulates the agricultural activities and quality of food production all over the world. This research work examines the effect of these climatic elements on Food Production in Africa: establishes standard Temperature level, amount of Rainfall and relative Humidity required for the optimal yields of Maize, Rice and Wheat; Predicts the optimal yields of these global crops; Investigates degree of loss to food productions in Africa. A 3 by 3 factorial experiment was used for data analysis, further test was carried out using Duncan Multiple Range Test to detect the most significance of the various levels of climatic elements used. Multiple regression analysis was adopted to obtain the normal levels for the three main factors. Thus, the derived Quadratic regression model: Yi=µ+αTi+βHi+ẟRi+λT2i+πH2i+τR2ii was used to predict yields of these crops. The result of the various data analysis shows that all the three climatic elements contributed significantly to the yields of the three crops. In some region of Africa, Temperature, Rainfall and Humidity exceed normal while in some region the three climatic elements were below normal which affected the yields of the crops. Thus, there is reduction in the food production in Africa between 2015 and 2016: Maize 9.489%, Rice 11.482%, Wheat 14.827%.

    » Simulation of an Intelligent Traffic Light using Embedded System

    » Owolafe O. and Olanrewaju O.S.

    ABSTRACT:

    The level of urbanization in developing nations indicates that more people live in cities than before. This increase heaviness on traffic flow and makes living in urban area complex. Traffic control at road junction which was done purely by human effort and expansion of roads remain inefficient owing to the increasing rate of both motorists as well as the complexity of road networks. This paper proposes that an intelligent traffic light in addition to existing traffic management techniques should be put in place to monitor traffic congestions. The traffic light system is designed using arduino uno microcontroller, ultrasonic sensor, liquid crystal display and light emitting diode (LED). For effective traffic control, the controller was programmed using C language. The designed traffic light control system was simulated on cardboard and using toy cars as model of the real vehicle.

    » Non Linear Fusion of Colors to Face Authentication using LDA

    » M. Fedias, D. Saigaa, M. S. Mimoune, M. Boumehraz

    ABSTRACT:

    In this article, we propose the use of information color to authenticate face; several spaces of colors were used for the transformation of colorimetric components RGB of the original images. The results obtained in different spaces/or component colorimetric are combined by the use of a nonlinear fusion with a simple neuron network type MLP (Multi layer perceptron). We applied the method of linear discriminant analysis (LDA) to extract the characteristic vector of the face image. To validate this work we tested this approach on frontal images of the data base XM2VTS according to its associated protocol (protocol of Lausanne).

    » Adaptation and Usability of Quick Response Codes for Subscription to Mobile Network Operators’ Services

    » Akande Noah Oluwatobi, Arulogun Oladiran Tayo, Adeyemo Isiaka Akinkunmi and Oyediran Mayowa Oyedepo

    ABSTRACT:

    Mobile Network Operators (MNOs) permit subscribers to gain access to data, voice calls or short messaging services offered by their networks. Payments for any of these services could be via online payments platforms, short codes provided by financial institutions or the acquisition of recharge vouchers. Of these payment methods, the recharge voucher acquisition option remains the most widely used. However, illegal access to the recharge codes has not been totally eradicated and this has marred the recharge vouchers payment method. Therefore, this paper examined and demonstrated the feasibility of employing Quick Response (QR) code as a more secured payment alternative to recharge vouchers. Twitter fabric’s crashlytics tool was used to evaluate the performance of the developed QR code mobile payment method for a three month periods. A successful payment attempt and crash free sessions were experienced among 48 volunteers who used the application in 125 sessions.

    » Development of an Enhanced AODV Energy Management model and Link Stability in MANET

    » Muhsin Hassanu Saleh and Alimi O. Maruf

    ABSTRACT:

    A mobile ad hoc network (MANET) nodes move arbitrarily and as a result the networks experience a rapid and unpredictable topology changes. The mobile nodes can receive and forward packets as router which leads to superfluous energy consumption. Routing being critical MANET makes this paper focus on one of the routing protocols i.e. Ad hoc On-Demand Distance Vector (AODV).To make the AODV more efficient with an enhanced route discovery procedure that will yield a reduction in the transmission delay that is caused due to instability of the path. Mobile nodes in MANET are battery dependant then suffers from limited energy level and as a result makes it difficult to recharge /replaced. Energy constraint in MANET lead to the development of an enhanced AODV (E-AODV) that reduces the variance in residual energy of the nodes, it also proposed a link stability parameter while selecting the path in order to increase the energy efficiency using a formulation for the link strength of the path that have the highest residual energy between the nodes. The enhanced AODV selects the path with the highest reliability and stability. Simulation was carried out using OPNET modeler for a different number of nodes in terms of delay, traffic sent and traffic received and the results shows that in any way the enhanced E-AODV outperforms the AODV.

    » Mukaila Olagunju, A. E. Adeniyi, S. E. Adewumi and U. S. Onyeabor

    ABSTRACT:

    Due to the problem that normally occur when colors are needed to be chosen for industrial uses, color are needed to be mixed together to generate new difference color. The algorithms were developed in two phases which consist of illustration algorithm and the other aspect which is the working algorithm which focus on the pattern of the mixing of any two colors in order to generated new color. Java programming language is used to develop the color mixture template as a guide for the users in industrial painting in order to know the likely match color, when two colors where to mixed together. This color mixture techniques algorithm will go a long way in generating the new color and will surely eliminate the issue of color riot when trying to use for industrial purpose and also help to showcase the beauty of color mixture.

    » Environmental Waste Management in Ilorin Metropolis using Software Application

    » Olagunju M. and Adeniyi, A. E.

    ABSTRACT:

    One of the major causes of death in Ilorin metropolis which is the capital of Ilorin Kwara State is the issue of environmental waste. Wastes are unused and rejected materials from household, schools, industries and highways. The waste materials are increasing as the population also increases. This paper aimed at developing a software model that is capable of predicting the waste generation and number of RORO bin needed based on population. Visual Basic programming was used to interpret the model developed and with this, we can predict the waste generation and number of RORO bin in One Dimensional representation. This will help both the government of Kwara state and Nigerian as a whole to tackle the environmental treat causes by waste generation by predetermine the number of RORO bin a particular environment or city we be needed. It will also assist the government to plan ahead especially in procurement of RORO bin and also reduce the number of disease (such as Malaria, Typhiod) which the government spends millions of Naira on yearly.
