ANALYSIS OF MECHANICAL ENGINEERING RESEARCH ACTIVITIES A CASE STUDY USING BIBLIO METRIC METHOD:A CASE STUDY OF UNDERGRADUATE PROJECTS

This study investigated the citation pattern of Mechanical engineering students in Landmark University, Nigeria.Biblio metric method was adopted, the study covered research projects submitted from 2015 to 2018. All the references of the research projects were examined one after the other and the different types of cited materials were recorded according to the year. It was discovered that the citations was high and multiple authored projects accounted for the that the citations on the projects increased on yearly basis. It was also revealed that journal articles accounted for the highest number of cited documents, it was also revealed that most of the cited materials ar that the students preferred to cite multiple authored materials, it was also discovered that the degree of collaboration by the students varies. Based on this research, the paper concluded that researchers should research so as to improve the research output of the undergraduate projects

COMPARATIVE ANALYSIS OF CITATION PATTERNS IN CIVIL AND MECHANICAL ENGINEERING RESEARCH PROJECTS

This study investigated the citation patterns in Civil and Mechanical Engineering research projects in a private university in Nigeria. The study adopted Bibliometric method was used to analyse the research projects submitted by graduates of the Department of Civil and Mechanical Engineering, Landmark University, Omu-Aran, Nigeria from 2016 to 2018. All the references of the research projects were examined. For each research project retrieved, data were obtained manually on some characteristics of cited materials. The findings revealed that the citation in the projects in the two programmes were high. The average number of citation per project was higher in civil engineering than mechanical engineering. It was also discovered that most of the cited documents were very recent in the two programmes. The findings also shows that the most cited materials in the two programmes was journal articles, followed by books among others. It was also discovered that mechanical engineering students cite more books and internet materials than civil engineering students. Also the result shows that civil engineering students cite more multiple authored materials than mechanical engineering students. Based on the findings, the study concluded and made recommendations

Figures of Merit for Wind and Solar PV Integration in Electricity Grids

349-357In future electrical grids, high levels of Variable Renewable Energy (VRE) penetration including solar photovoltaics (PV) and wind energy is expected. This poses a challenge in system operation and planning especially in balancing electricity demand and supply. This paper examines figures of merit for wind and solar integration in electricity grids. Quantitative tools such as load duration curves, correlation analyses, and the Fourier transform were used to study the intermittency/variability of wind and solar PV power. Time series data on power production from the European Network of Transmission System Operators for Electricity (ENTSO-E), and Réseau de Transport d'Électricité (RTE) were used for the analyses. The analyses illustrate that despite the valuable amount of energy that can be obtained from wind and solar PV, these energy sources cannot be used as baseload power supply. Solar PV power is available for approximately 50% of the time year-round. Wind power output on the other hand can reach very small magnitudes of just a few megawatts several times in a year. More to that, wind is positively correlated over long distances, even exceeding 3000 km and aggregating wind fleets over a large geographic area might not guarantee continuous availability of wind power. Nonetheless, these sources can still be integrated in electricity grids in high proportions, provided intermittency mitigation options such as energy storage, curtailment, and demand-response are implemented

Dataset on cellular and geo-spatial information of a 10 km distance along Akure-Ilesha road

This dataset contains cellular and geo-spatial information of a 10 km distance along Akure-Ilsha road in Ondo state, Nigeria. The data was acquired using a designed data acquisition system which was kept inside golf3 vehicle interfaced with Acer laptop, the data was acquired as the vehicle moves from the reference point (7.39919, 5.05944 ) to its destination point (7.32818, 5.10836), it harvests GSM signal Strengths from a base station in intervals with its time, latitude and longitude simultaneously as the vehicle moves along the travelled rout; the data acquired shows the variation of signal strength against distance along the road from one base station to another in the travelled path. The raw data of this work is hosted in the Mendeley repository DOI:10.17632/tmksc8mkt8.

Design, modelling, energy and exergy analysis of a parabolic cooker

A functional parabolic solar cooker was designed and constructed to serve as an alternate renewable source of energy for cooking and to also reduce the adverse effects of other sources of energy on the environment. The solar cooker was fabricated using cheap, locally sourced available materials in Nigeria. Experimental investigation was carried out on the produced model in Omu-Aran Metropolis, Kwara State, Nigeria in December 2016. Thereafter other investigations were carried out from January to December 2017 and lastly in January 2018 between the hours of 10:00 a.m. to 5:00 p.m. local time for both stagnation and sensible heating, using 2 L of water at every experiment. The average energy and exergy efficiencies of the parabolic cooker were about 39% and 44% respectively. The instability of the energy efficiency occurred as a result of optical and thermal losses from the reflector and pot, as well as the varying environmental conditions. Mathematical expressions were used to calculate the theoretical values of energy and exergy efficiencies using Minitab, while the statistical analysis showed that there was no significant difference between the experimental and predicted results for exergy and energy efficiencies of both cookers at p > 0.05, this validated the design.
