    The study was carried out on organizational structure and sports personnel satisfaction in Nigeria South West Tertiary Institutions. To this end, a total of 200 sports personnel’s that cut across four institutions, that is, LASU, UNILAG, UI, and Ibadan Poly, were selected through a stratified random sampling technique and served as respondents in the study. A self-developed and validated questionnaire was the instrument used for data collection. Fifty (50) copies of the questionnaire were administered in each of the institutions using on the spot administration for high percentage returns. The data collected was used to develop a frequency distribution table for analysis. The descriptive statistics of percentage, bar, and pie charts were used for data presentation, while the t-test statistical tool was used in testing all stated hypotheses using 0.05 confidence levels. The findings show that Organizational structure, Reward, and Communication have significant influences on sports personnel satisfaction in Nigeria South-west Tertiary institution, it can also be depicted that for the development of any institution or sport academic, the organizational structural effects of the sports personnel need to be structured appropriately to promote healthy living

    DEVELOPMENT OF A 0.5KW HORIZONTAL AXIS WIND TURBINE

    Wind turbine is a machine that is powered by the energy from the wind. It is designed to convert the kinetic energy from the wind into electrical power (electricity). This study focus on the development of 0.5KW horizontal axis wind turbine. The major components of the wind turbine which include the blades, hub, shaft and the tower, were design and fabricated to meet the required 0.5 KW and the turbine was mounted on a tower height of 5m from the sea level. The test result showed that the wind turbine is capable of producing about 500 W, at a rotor speed of 153.5 rpm. The necessary design details that have been applied at the design and fabrication stages of the wind turbine guarantees the high hope of this wind turbine performing better

    A Plan for Igniting Nigeria’s Industrial Revolution

    The Industrialization of countries is in every way influenced by forerunner nations. This is exemplified in Western Europe’s copying of Britain’s technology and manufacturing systems. This work presents a study of the industrialization of nations such as Japan, South Korea, Taiwan, Singapore and several other industrializing countries and the lessons learned revealed that the industrialization of these nations was based on initial imitative-reverse-engineering of products of forerunner nations which then leads to endogenous growth and the onset of innovation under certain constraints. This is a strategic form of import substitution and is in fact the model around which a plan for Nigeria’s Industrialization has been buil

    Current biometric methods for attendance are too intrusive. This paper presents a stress-free non-intrusive way of taking class attendance using face as the biometric. It also has the added novelty of relaying vital information about class attendance to handheld devices via any available cellular network. During enrollment, a camera was used to acquire facial images that were made into templates using Fisherfaces algorithm. These templates were stored in a database. During verification or attendance taking, facial features extracted from acquired face images and stored picture templates were compared using Fisher Linear Discrimination algorithm for any match within the pre-set threshold. Vital information about collated attendance reports were sent via a cellular network to designated handheld devices. The designed and implemented system had 54.17% accuracy during verification when lighting was varied without any variation in facial expression during enrollment. The system had 70.83% accuracy during verification when facial expressions were varied along with variations in lighting conditions during enrollment

    AN AUTOMATED ENERGY METER READING SYSTEM USING GSM TECHNOLOGY

    The measurement of the energy consumed by residential and commercial buildings by utility provider is important in billing, control and monitoring of the usage of energy. Traditional metering techniques used for the measurement of energy are not convenient and is prone to different forms of irregularities. These irregularities include inaccuracies in billing due to human error, energy theft, loss of revenue due to corruption and so on. This research study proposed the design and construction of a microcontroller based electric energy metering system using the Global System for Mobile communication (GSM) network. This system provides solution to the irregularities posed by the traditional metering technique by allowing the utility provider have access to remote monitoring capabilities, full control over consumer load, and remote power disconnection in the case of energy theft. Proteus simulation software was used to model the system hardware and the software was obtained by using embedded C programming and visual basic. It was observed that the system could remotely take accurate energy readings, provided full control over consumer loads and execute remote disconnection in case of energy theft. The system provides high performance and high accuracy in power monitoring and power management. Keywords: GSM, Automati

    A Bimodal Biometric Student Attendance System

    A lot of attempts have been made to use biometrics in class attendance systems. Most of the implemented biometric attendance systems are unimodal. Unimodal biometric systems may be spoofed easily, leading to a reduction in recognition accuracy. This paper explores the use of bimodal biometrics to improve the recognition accuracy of automated student attendance systems. The system uses the face and fingerprint to take students’ attendance. The students’ faces were captured using webcam and preprocessed by converting the color images to grey scale images. The grey scale images were then normalized to reduce noise. Principal Component Analysis (PCA) algorithm was used for facial feature extraction while Support Vector Machine (SVM) was used for classification. Fingerprints were captured using a fingerprint reader. A thinning algorithm digitized and extracted the minutiae from the scanned fingerprints. The logical technique (OR) was used to fuse the two biometric data at the decision level. The fingerprint templates and facial images of each user were stored along with their particulars in a database. The implemented system had a minimum recognition accuracy of 87.83%

    ATM was introduced to boost the cashless policy in Nigeria. Current trend of Cybercrime facilitate the need for an enhanced fingerprint application on ATM machine with GSM Feedback mechanism. The mechanism enable unassigned fingerprint authentication of customers with quick code and secret code. The project enhances the security authentication of customers using ATM. A core controller using fingerprint recognition system of ATmega128 in-system programmable flash is explored. An SM630 fingerprint module is used to capture fingerprints with DSP processor and optical sensor for verification, using AT command of GSM module for feedback text messaging (i.e. sending of Quick and Secret-Codes respectively). Upon system testing of capable reduction of ATM fraud using C program, the new method of authentication is presented
