Learning analytics for smart campus: Data on academic performances of engineering undergraduates in Nigerian private university
Empirical measurement, monitoring, analysis, and reporting of learning outcomes in higher institutions of developing countries may lead to sustainable education in the region. In this data article, data about the academic performances of undergraduates that studied engineering programs at Covenant University, Nigeria are presented and analyzed. A total population sample of 1841 undergraduates that studied Chemical Engineering (CHE), Civil Engineering (CVE), Computer Engineering (CEN), Electrical and Electronics Engineering (EEE), Information and Communication Engineering (ICE), Mechanical Engineering (MEE), and Petroleum Engineering (PET) within the year range of 2002–2014 are randomly selected. For the five-year study period of engineering program, Grade Point Average (GPA) and its cumulative value of each of the sample were obtained from the Department of Student Records and Academic Affairs. In order to encourage evidence-based research in learning analytics, detailed datasets are made publicly available in a Microsoft Excel spreadsheet file attached to this article. Descriptive statistics and frequency distributions of the academic performance data are presented in tables and graphs for easy data interpretations. In addition, one-way Analysis of Variance (ANOVA) and multiple comparison post-hoc tests are performed to determine whether the variations in the academic performances are significant across the seven engineering programs. The data provided in this article will assist the global educational research community and regional policy makers to understand and optimize the learning environment towards the realization of smart campuses and sustainable education
Learning attributes of summa cum laude students: Experience of a Nigerian university
In this project, 276 students at a private university in Nigeria completed
a survey concerned with their personal attributes and study dispositions. First class
(summa cum laude) students were compared with third class (less successful)
students. Differences were not found in their goal setting habits, and declaration of
healthiness. The third class students indicated higher levels of participation in sporting
activities. The first class students reported higher levels of spirituality and Bible
reading. When asked about their use of basic study skills, the two groups reported
fairly similar levels, but then they diverged strongly on deeper learning approaches,
with the first class students reporting higher levels of deep study strategies
Learning analytics: Dataset for empirical evaluation of entry requirements into engineering undergraduate programs in a Nigerian university
In Nigerian universities, enrolment into any engineering undergraduate program requires that the minimum entry criteria
established by the National Universities Commission(NUC)must
be satisfied. Candidates seeking admission to study engineering
discipline must have reached a predetermined entry age and met
the cut-off marks set for Senior School Certificate Examination
(SSCE), Unified Tertiary Matriculation Examination(UTME),and
the post-UTME screening.However, limited effort has been made
to show that these entry requirements eventually guarantee successful academic performance in engineering programs because
the data required for such validation are not readily available.In
this data article, a comprehensive data set for empirical evaluation
of entry requirements into engineering undergraduate programs in
a Nigerian university is presented and carefully analyzed. A total
sample of 1445 undergraduates that were admitted between 2005
and 2009 to study Chemical Engineering(CHE), Civil Engineering
(CVE), Computer Engineering(CEN), Electrical and Electronics
Engineering (EEE),Information and Communication Engineering
(ICE), Mechanical Engineering(MEE),and Petroleum Engineering
(PET) at Covenant University,Nigeria were randomly selected. Entry age,SSCE aggregate, UTME score, Covenant University
Scholastic Aptitude Screening(CUSAS)score, and the Cumulative
Grade Point Average(CGPA) of the undergraduates were obtained
from the Student Records and Academic Affairs unit. In order to
facilitate evidence-based evaluation, the robust dataset is made
publicly available in a Microsoft Excel spreadsheet file. On yearly
basis, first-order descriptive statistics of the data set a represented
in tables. Box plot representations, frequency distribution plots,
and scatter plots of the dataset are provided to enrich its value.
Furthermore, correlation and linear regression analyses are performed to understand the relationship between the entry
requirements and the corresponding academic performance in
engineering programs. The data provided in this article will help
Nigerian universities, the NUC, engineering regulatory bodies,and
relevant stakeholders to objectively evaluate and subsequently
improve the quality of engineering education in the country
A Camera-Only Based Approach to Traffic Parameter Estimation Using Mobile Observer Methods
As vehicles become more modern, a large majority of vehicles on the road will have the required sensors to smoothly interact with other vehicles and infrastructure on the road. There will be many benefits of this new connectivity between vehicles on the road but one of the most profound improvements will be in the area of road accident prevention. Vehicles will be able to share information vital to road safety to oncoming vehicles and vehicles that are occluded so they do not have a direct line of sight to see a pedestrian or another vehicle on the road.
Another advantage of these modern connected vehicles is that different traffic parameters can be more easily estimated using the onboard sensors and technologies in the vehicles. For many decades traffic engineers have been able to estimate different traffic parameters like traffic flow, density, and velocity based on how many vehicles the primary vehicle passes and how many vehicles pass the primary vehicles. For much of the time that traffic engineers have been working on traffic estimation, it has been done using more manual and tedious methods. In this paper, a more novel approach of determining these traffic parameters is used.
Also, one of the problems with traffic parameter estimation is that sometimes the results are not accurate because of vehicles that might not have been counted because of occlusion. In this paper, a proposal is put forward on how this can be remedied utilizing the connected vehicle\u27s framework
Fluid Shift and Fluid Resuscitation in Burn Patients with the use of Bio-Electrical Impedance Spectroscopy to Monitor Fluid Levels
The purpose of this research is to explore the current methods of fluid resuscitation and other possible methods of measuring the body fluid levels of burn patients in order to fully understand the fluid increase patterns in the torso area. This will be done primarily by focusing on the concept of bio-electrical impedance spectroscopy to measure the fluid levels only in the human torso area. Three similar tests were carried out by measuring the resistance values after ingesting 500ml of water. This was repeated until a total of 1500ml of water was ingested. It was found that the resistance in the extracellular fluid (R0) appear to not be significantly affected by the increase in fluid intake but the resistance in the intracellular fluid (R∞) show a greater difference. This can be due to a variety of conditions including the path flow of the ingested water content. The resistance measurements from the back of the torso posed to be more accurate than that of the front of the torso. This can also be connected to the water path flow. In order to further study the chosen electrode placements and understand the cause of the difference between the front and back torso results, more focused tests will be carried out in the future
SPATIO-TEMPORAL INFORMATION SYSTEM ANALYSIS OF REVENUE ALLOCATION IN NIGERIA (1999-2008)
The bulk of the federally allocated revenue derived from revenue accruing to the Federal Government of Nigeria is shared with the other two tiers of government under a revenue allocation system (RAS) using different formulas at different times. The sharing principle has remained a contentious issue to date. This paper presents a spatio-temporal analysis of three items of revenue allocation namely, statutory, excess crude oil, value added tax and 13% share of derivation shared among the three tiers between May 1999 – December 2008. A comparative analysis was conducted among 6 geo-political zones, 36 states and 774 local government areas of the country. The result shows that when allocations from the four items of revenue are combined, the South-South zone leads with incredible margin, thus raising questions about the legitimacy of agitations from this zone
Socio-Economic Benefits of Iroko Trees (Milicia excelsa Welw C.C. Berg) in Ibadan Metropolis, Oyo State, Nigeria
A complete survey of Iroko trees in Ibadan metropolis was carried out with the view to determining their distribution and status. The entire of Ibadan City was considered for the study. The city was divided into sections and a reconnaissance survey was conducted to confirm existence of the tree species within each of the section. Direct observation of the already identified Iroko trees was then carried out during the actual data collection stage of the study. Permissions were sought before data collection was carried out on the identified trees. A total of 62 Iroko trees were surveyed; out of these, 33 (53.2%) stands were accessible while the remaining 29 stands (46.8%) were inaccessible. Many of the trees that could not be accessed were a result of restriction into the location where they exist. The most frequently observed benefit obtained trees are shade from direct sunlight and cool breeze it creates. Other uses of trees include peeling of the tree bark and used in preparation of local medicine, fetish activities on and around the tree, and use of the fallen branches as firewood. There is urgent need for appropriate protection strategies of these remaining indigenous tree species where they exist.

SEN-Iot: A Smart Emergency Notification System Suitable for Developing Countries using Internet of Things
Research has shown that disaster effects on properties and lives can be drastically reduced through wide dissemination of information on the impending danger to people at the appropriate time. Generally, the emergency alert systems are usually proactive systems; they are meant to gather data in surrounding using the necessary tools, alert the specified listeners about an impending danger and gives suggestion on the necessary actions to be taken in each situation. In addition, some emergency alert systems also activate automatic responses. Furthermore, the integration of Internet of things (IoT) technology with emergency notification systems is rapidly attracting new discovery in this domain. In this paper, an effective smart emergency notification system named SEN-IoT was design using IOT technology. SEN-IoT was modeled to manage domestic hazard with a scope of water, fire and gas leaks; by creating an emergence notification and immediate response systems. The SEN- IOT was implemented using arduino, sensors and the GSM module. The system was tested for maintainability, functionality, efficiency, usability and reliability, and results revealed that SEN-IoT can effectively handle domestic hazard
Auctioneering in the Practice of Estate Surveyors and Valuers
There has been recent agitation amongst estate surveyors and valuers that auctioneering ought to
be an aspect of their practice. This crave for supremacy appears contestable as they have not had
an exclusive preserve in this aspect of practice coupled with the participation of other
professionals. This study thereby aimed at discovering the prospect of estate surveyors and
valuers in auctioneering amongst various stakeholders. Questionnaires were distributed to one
hundred and eighty-three (183) estate surveyors and valuers in Lagos State, thirty-nine (39)
auction houses in Lagos state and eleven (11) government agencies who require the services of
auctioneers. The use of descriptive and inferential statistics such as the Relative Importance
Index (RII), Chi-square test and Kruskal-Wallis test of significance were used in the analysis of
the data. It was revealed that although the proportion of estate surveyors and valuers engaged in
auctioneering are quite minimal, they are still substantial compared to other contending
professionals. Estate surveyors and valuers are being vaunted to handle auctioneering even
though caution has to be applied in the result not being significant at the 5% significant level but
significant at the 1% level of significance. The need for professionals exclusively known as
auctioneers was advocated. The researchers thereby opine that the inclusion of auctioneering in
the curriculum of all higher institutions offering estate management will be a welcome
development that will give the estate surveyors and valuers the hedge for specialization as the
professional auctioneer being advocated from responses in the study
