A Review of Mechanical Strength Properties of Some Selected Timbers in Nigeria
(THE INTERNATIONAL JOURNAL OF SCIENCE & TECHNOLEDGE, 2016-02) Adeyemi, F. O.; Jimoh, A. A.; Wilson, U. N.
The variation in mechanical properties of eight different timber species was reviewed from the project works on timber carried out in the Department of Civil Engineering, University of Ilorin. Kwara state, Nigeria. These species include Iroko (Chlorophora excelsa), Mahogany (Khaya ivorensis), Fanpalm (Borassus aethoiopum), Ekki (Lophira alata), Opepe (Nauclea diderrichii), Apa (Afzelia, bipindensis), Ayin (Anogeissus leiocarpus), Afara (Terminalia superba). The Annual Book of ASTM Standard Section 4, (D143), method of testing small clear specimens of timber was adopted to evaluate the variation of strength properties of the species from standard speed and dimension specifications. The strength properties reviewed were, compression parallel to grain, compression perpendicular to grain, static bending (flexure) and tensile strength parallel to grain. From the review, it was found that strength of timbers along the grain is far greater than across or perpendicular to grain showing the anisotropic nature of timber. Prior soaking of the specimen before test accounts for reduction in strength. Also deviations from the specified dimensions and speed of testing of specimen will in one way or the other affect the accuracy of strength obtained in the test. It is therefore recommended that strict adherence to the test procedure and specifications should be followed so as to achieve the exact strength values of timbers and that further research work be done on other timbers in order to maximize their usefulness as a construction material.
Design and Implementation of a GSM based Electronic Appliances Monitoring and Controlling System
(International Journal of Advanced Research in Computer and Communication Engineering, 2016-03-01) Oyediran, Mayowa Oyedepo; Akande, Noah Oluwatobi
This paper presents a GSM based electronic appliances monitoring and controlling system. This enables individuals to connect their home or office electronic appliances to the developed system which in turn enables them to remotely monitor and control these appliances though a Short Message Service (SMS). In remotely controlling the connected electronic appliances, users can determine the status of the electronic appliances remotely and decide whether to either switch any of the connected electronic appliances on or off. The uniqueness of the approach introduced is further revealed in the way the GSM module of the developed system was integrated with thePIC16F877Amicrocontroller to give a single and more compact system. Also, the SMS format used in monitoring and controlling the connected electronic appliances allows users to control their electronic appliances from anywhere provided there is a GSM network; hence, distance was not a barrier. The SMS format used is not lengthy and is simple to understand which makes it attractive to its users. The performance of the developed system was evaluated by connecting twelve (12) electronic appliances with it and the developed system shows the capability to remotely monitor and control them.

(Circulation in Computer Science, 2016-05-05) Amusan, D. G.; Oyediran, M.O.
The development of e-recruitment system is web-based tool used in order to reduce communication gap between job seekers and employers. E-recruitment, also known as online recruitment, is the practice of using technology and in particular Web-based resources for tasks involved with finding, attracting, assessing, interviewing and hiring new personnel. Most of the existing mode of recruitment (manual recruitment) takes much time in processing the application form, existing system will not automatically send feedback to all applicant whose meet up with the job requirement but with the help of the developed system there is reduction in time to process the application form and there is automatic feedback from the employer to the job seeker that meet up with requirement. The objective of this work is to developed an efficient e-recruitment system capable of managing all stages of the e- recruitment process, including multi-job posting, agency channel management and candidate filtering to identify the most relevant candidates...
Development of an Optimized Mobile Agent Migration Pattern for Pull-All Data Strategy
(British Journal of Mathematics & Computer Science, 2016-05-22) Oyediran, M. O.; Fagbola, T. M.; Olabiyisi, S. O.; Omidiora, E. O.
A mobile agent is a software entity that migrates from one host to another, performing data collection and software configuration tasks on behalf of users in distributed networks. However, studies have shown that the existing pull – all data strategy of mobile agent migration pattern moves data from one host to the next host along with the mobile agent, thereby resulting in data accumulation which lowers the performance of the mobile agent in terms of transmission time and network load. This research developed an optimized mobile agent migration pattern for the pull-all data strategy in distributed networks using path strategy of Ant Colony Optimization (ACO) technique. The obtained results shows that the optimized pull-all data migration pattern developed produced lower network load and transmission time than the existing pull-all data migration pattern.

Not only in the wide range of commercial and law enforcement applications, but also the availability of feasible technologies, Although current migration process of mobile agent systems have reached a certain level of maturity, Autonomous migration of mobile agent is an area that has witnessed a lot of research activity and their development is still limited by the conditions brought about by many real applications. Several approaches have been proposed for the migration process of mobile agent. This paper provides an up-to date survey of migration process of mobile agent research. To present a comprehensive survey, we categorize existing mobile agent migration process approaches and present detailed descriptions of representative methods within each category with special focus on the soft computing approaches.
FEASIBILTY STUDIES OF A PROPOSED HYBRID POWER GENERATION SYSTEM FOR A COMPUTER CENTER IN A REMOTE STATION
(International Journal of Technical Research and Applications, 2016-08-01) Omogoye, Okeolu Samuel; Ogundare, Ayoade Benson; Oyetola, Jamiu Babatunde; Keshinro, Kolawole Kazeem; Adenle, Johnson Gbadebo
This paper presents the feasibility study of a proposed Photovoltaic/Diesel power generation hybrid system for a remote computer centre in Nigeria. This design comprises the correct determination of station electrical daily load consumption and station solar radiation data. These data are used to determine the hybrid components sizes and its configuration via the use of HOMER software for design and simulation. The simulation results were used to carry out the optimization of this system based on twenty five years life expectances. Analyzing the hybrid power generation system (HPGS) helps in determining the cost effect, the level of emission and optimizes the size of the system. This analysis shows that the HPGS has lower cost, emit less harmful gaseous substances and give reasonable system sizes leading to reduction of energy wastage as compared to conventional stand alone Diesel generator. However, the final design perfectly meets the station energy requirement. Hence, (HPGS) is a recommended solution for this application.
AN ENHANCED PRINCIPAL COMPONENT ANALYSIS APPROACH FOR EXTRACTING FEATURES IN PALMPRINT IMAGES
(International Journal of Emerging Technology in Computer Science & Electronics (IJETCSE), 2016-09-15) Akande, Noah Oluwatobi; Oyediran, Mayowa Oyedepo; Ogundokun, Roseline Oluwaseun; Adeyemo, Isiaka Akinkunmi
In reducing the dimensions of feature space so as to achieve better performance, minimal features that yet represent the original image maximally need to be extracted. Principal Component Analysis (PCA) which is an appearance based projection method has been widely used in this regards. Literatures have shown that PCA performs well for dimensionality reduction but instead of reducing within class variations, it increases it therefore resulting in its low performance. In contrast, Independent Component Analysis (ICA) performs preferably well in this instead since it linearly transforms an original data into completely independent components thereby reducing within class variations. While both PCA and ICA have been used for the purpose of feature extraction, no single feature extraction algorithm is exclusively flawless in all ramifications. In lieu of this, this paper introduces an Enhanced Principal Component Analysis (EPCA) approach which first extracts principal components from data and further uses the extracted components as input to an ICA algorithm. The EPCA was employed for feature extraction in a palmprint recognition system. The resultant system was validated using 900 palmprint images which were downloaded from three public palmprint databases. Recognition and verification rates arising from the palmprint recognition system showed that the EPCA performed well than PCA algorithm.

(Waste Management, 2017-07-11) Odedina, Mary Jesuyemi; Charnnok, Boonya; Saritpongteeraka, Kanyarat; Chaiprapat, Sumate
Methane production potential of tropical fruit wastes, namely lady-finger banana peel, rambutan waste and longan waste were compared using BMP assay and stoichiometric modified Buswell and Mueller equation. Methane yields based on volatile solid (VS) were in the order of ground banana peel, chopped banana peel, chopped longan waste, and chopped rambutan waste (330.6, 268.3, 234.6 and 193.2 mLCH 4 / gVS) that corresponded to their calculated biodegradability. In continuous operations of banana peel digestion at feed concentrations based on total solid (TS) 1–2%, mesophilic single stage digester run at 20-day hydraulic retention time (20-day HRT) failed at 2%TS, but successfully recovered at 1.5%TS. Pre- hydrolysis thermophilic reactor (4-d HRT) was placed as pre-treatment to mesophilic reactor (20-d HRT). Higher biogas (with an evolution of H 2 ) and energy yields were obtained and greater system sta- bility was achieved over the single stage digestion, particularly at higher solid feedstock. The best perfor- mance of two stage digestion was 68.5% VS destruction and energy yield of 2510.9 kJ/kgVS added at a feed concentration of 2%TS.

(FERVAAP, 2017-07-25) Odedina, Mary Jesuyemi; Saritpongteeraka, Kanyarat; Charnnok, Boonya; Chaiprapat, Sumate
Methane production potential of tropical fruit wastes were compared by anaerobic digestion assay and stoichiometric Buswell's equation. Methane yields were in the order of banana peel, longan waste, and rambutan waste (330.6, 268.3, 234.6 and 193.2 mLCH 4 /gVS). Their calculated biodegradability related well with structural composition and properties. In continuous system operations on banana peel at feed concentrations 1%TS and 2%TS, mesophilic single stage digester (20-day HRT) failed at 2%TS. Prehydrolysis thermophilic reactor (4-d HRT) was placed as pre-treatment to mesophilic reactor (20-d HRT). Higher biogas and energy yields were obtained and greater system stability was achieved over the single stage digestion. The energy yield of 2510.9 kJ/kgVS was achieved at a feed concentration of 2%TS with thermophilic prehydrolysis.

(Journal of Scientific Research & Reports, 2017-12-08) Adeyemo, Temitope Tosin; Adepoju, Temilola Morufat; Sobowale, Adedayo Aladejobi; Oyediran, Mayowa Oyedepo; Omidiora, Elijah Olusayo; Olabiyisi, Stephen Olatude
One of the most common diseases in women today is breast cancer. The method of detection and analyzing breast images according to literature, to mention few are mammography, magnetic resonance, thermography and ultrasound of which mammography is the most accurate and low cost method. Mass is a major symptom of breast abnormality. Despite the high success of mammography in mass detection, radiologists find it difficult to interpret breast abnormality and take decision. Computer Aided Detection (CADe) and Computer Aided Diagnosis (CADx) are the two systems to improve radiologists’ accuracy of detection and, classification of breast cancer into benign or malignant prior to biopsy. However, the optimal classification rate of CAD system depends on effectiveness of feature extraction technique. This paper present review of different feature extraction Techniques (FETs) that have been adopted for mass detection and classification.
ADAPTATION AND USABILITY OF QUICK RESPONSE CODES FOR SUBSCRIPTION TO MOBILE NETWORK OPERATORS’ SERVICES
(Anale. Seria Informatică., 2018-03-01) Akande, Noah Oluwatobi; Arulogun, Oladiran Tayo; Oyediran, Mayowa Oyedepo
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.

(International Journal of Computers & Technology, 2018-03-16) Oyediran, Mayowa Oyedepo; Wahab, Wajeed Bolanle; Elegbede, Adedayo Wasiat; Enegbe, Toye Jolie
Security is crucial all around. Access into institutions, examination centers, organizations or even estates ought to be controlled and closely monitored through a verification system. The method of authenticating a student for an examination has an obvious problem such as presentation of fake clearance card, impersonation and so on and the unethical manner associated with the examination is a grim issue that requires the stakeholders in academic area to seek for alternative means of authenticating student for examination, because the manual paper-based clearance process is fundamentally flawed. Sequel to that, a dependable and effective system is designed to tackle the issues of the convectional technique. The system will verify the understudy using fingerprint biometrics technique and generate a report which can serve as an attendance.
An Embedded Arduino based LPG Detection System with SMS Alert and Automatic Gas Shut Off
(Journal of Scientific and Engineering Research, 2019-02-03) Olusanya, Olamide O.; Oyediran, Mayowa O.; Usman, Musa; Elegbede, Adedayo W.; Fawole, Ayobami O.; Adebo, King
The level of technological advancement which engendered enhanced transportation of Liquefied Petroleum Gas (LPG) has, to a large extent, solved the problem of energy demand. Unfortunately, in doing this, it brought about concomitant risk- damage to the pipes as a result of human errors, natural disasters, and acts of vandalism. This paper addresses the issue of gas leakage and proposes a leakage detection system using an MQ 2 gas sensor, a buzzer, and a GSM module. A response mechanism which shut off the supply of gas when the level of leakage seems not to reduce.
Towards maximising the integration of renewable energy hybrid distributed generations for small signal stability enhancement: A review
(International Journal Energy Res. 2020, 2019-08-12) Ajeigbe, Olusayo A.; Munda, Josiah L.; Hamam, Yskandar
Integrating renewable energy hybrid distributed generation (REHDG) into distribution network systems (DNSs) has become increasingly important because of various technical, economic, and environmental advantages accruing from it. However, the output power of REHDGs from photovoltaic (PV) and wind is highly variable because of its dependency on intermittent parameters such as solar irradiance, temperature, and wind speed. Such variability of generated power from large-scale REHDGs or load introduces small signal instabilities (oscillations). Meanwhile, different locations of integration and sizes of REHDGs in the DNS affect the system oscillation modes by either improving or depriving the small-signal stability (SSS) of the network. Consequently, a significant number of research has been conducted on the planning of optimal allocation of REHDGs in DNS. In this regard, this paper reviews the existing planning models, optimisation techniques, and resources' uncertainty modelling employed in REHDGs allocations in terms of their capability in obtaining optimal solutions and enhancing SSS of the system. Planning models with optimisation algorithms are evaluated for modelling renewable resource uncertainties and curtailing SSS variables. Researchworks on planning of optimal allocation of these generations attain minimum cost, but were unable to satisfy the SSS requirements of the system. The existing models for the planning and design of optimal timing, sizing, and placement of REHDGs will need to be improved to optimally allocate REHDGs and satisfy the SSS of the DNS after the integration.

In e-commerce, credit card fraud is an evolving challenge. The increase in the number of credit card transactions provides more opportunity for fraudsters to steal credit card numbers and execute fraud. Fraud detection is a continuously evolving discipline to tackle ever changing tactics to commit fraud. Existing fraud detection systems have not been so much efficient to reduce fraud transaction rate. Improvement in fraud detection practices has become essential to maintain existence of payment system. This research designed hybrid of Counter Propagation Neural Network and genetic algorithm (CPNN-GA) for the detection of anomaly in any online transactions.

Optimal Allocation of Renewable Energy Hybrid Distributed Generations for Small-Signal Stability Enhancement
(2019-11-14) Ajeigbe, Olusayo A.; Munda, Josiah L.; Hamam, Yskandar
wind, and biomass takes into consideration the impact assessment of variable generations from PV and wind on the distribution networks’ long term dynamic voltage and small-signal stabilities. Unlike other renewable distributed generations, the variability of power from solar PV and wind generations causes small-signal instabilities if they are sub-optimally allocated in the distribution network. Hence, the variables related to small-signal stability are included and constrained in the model, unlike what is obtainable in the current works on the planning of optimal allocation of renewable distributed generations. Thus, the model is motivated to maximize the penetration of renewable powers by minimizing the net present value of total cost, which includes investment, maintenance, energy, and emission costs. Consequently, the optimization problem is formulated as a stochastic mixed integer linear program, which ensures limited convergence to optimality. Numerical results of the proposed model demonstrate a significant reduction in electricity and emission costs, enhancement of system dynamic voltage and small-signal stabilities, as well as improvement in welfare costs and environmental goodness
