Delaying transition in a Blasius boundary layer with finite compliant panels
(Fourth International Symposium on Bifurcations and Instabilities in Fluid Dynamics (BIFD),, 2011-07-18) Bori Ige; Zhao, .X.; Yeo, .K. S.
Compliant surfaces have been shown to be a promising passive control measure for controlling and delaying boundary layer transition in various theoretical studies [1-2]. In this paper, we report on a recent study we have done on the evolution of pulse-initiated disturbance wavepackets over one or more finite-length compliant panels. The broadband nature of a wavepacket offers a central advantage in permitting natural selection of most dominant waves to operate through the sum of its growth processes. This may be helpful in identifying the critical waves and key processes that are involved at the various stages in natural transition. The initiation, evolution and final breakdown of wavepackets into the incipient turbulent spots in a Blasius boundary layer was modelled by Direct Numerical Simulation (DNS) briefly described in [3]. The comparative evolution and transition performance of three cases are discussed here, namely the rigid-wall case, a single-panel wall and a two-panel wall. In all cases, a fixed vertical-directed delta pulse of small amplitude was initiated at the point x /  349.4, where   2.3182103m is the displacement thickness of the boundary layer at the initiation point. The evolution and breakdown of the wavepacket in a Blasius boundary layer on a rigid wall has already been reported in [3]. For the single-panel case, a finite section of the wall from x /  450 to 762 was replaced by a tensioned membrane on a viscoelastic foundation, whose properties were designed to inhibit the development of compliant-wall modes. The simulation results showed that, the upstream intervention by the finite compliant panel effectively delayed the onset of the incipient turbulent spot by a distance of about 100 cm ( x /  430). This represents an approximately 30% increase in the transition distance measured from the point of wavepacket initiation. Spectral study indicated that the relatively short membrane panel was able to effectively attenuate the primary 2-D Tollmien-Schlichting (TS) wave mode so that resultant wavepacket after the panel was dominated by a pair of oblique waves. Subharmonic secondary instabilities [4-5], which are responsible for nonlinear disturbance wave amplification on a rigid wall, were thus inhibited by the absence or near absence of the 2-D TS wave mode. Staggered Λ-structures and streamwise streaky structures similar to those found in the rigid wall case were observed for the single-panel case, but much further downstream. A second tensioned membrane panel of the same length was added at x /  1359-1658 to form the two-panel case. The last stage of the present simulation shows the wavepacket arriving the location x /  2000 in a perfectly laminar form ( max | u | /U 0.05   ) – this already represents an increase in transition distance of about 50% over the corresponding rigid-wall case. The eventual breakdown location will be further downstream as the wavepacket has not displayed the usual structural features that signify imminent breakdown. This study has shown the efficacy of short compliant panel(s) in controlling and delaying transition.
Delaying transition further with the aid of a short compliant panel in a Blasius boundary layer flow
(The Chinese Society of Theoretical and Applied Mechanics (CSTAM), Fluid Mechanics Division Conference, Guilin, China., 2012-11-12) Bori Ige; Yeo, .K. S.; Dou, .H-S.; Zhao, .X.
The cost of fuelling especially for those in the transport industries could be reduced drastically if there is a means of reducing drag force over their vehicles while in motion. One way to overcome this is to use compliant (membrane) surface; a passive control means which has been proved in various theoretical studies as a promising tool in delaying transition further. In this paper, following the earlier work done on flow over rigid wall within a Blasius boundary layer, we account for the current study carried out on the evolution of pulse-initiated disturbance wavepackets over a finite-length compliant panel by direct numerical simulation (DNS) method. For the single-panel case, a finite section of the wall from X = x/δ0 = 450 -762, was replaced by a tensioned membrane on a viscoelastic foundation, whose properties were designed to inhibit the development of compliant-wall modes. Where δ0 is the displacement thickness at the perturbation location. A small amplitude vertical initiating delta pulse was introduced from the wall streamwise location X0 = 349.4 (x0 = 81cm), and study in detail both spatially and spectrally how the wavepackets generated evolve from the initiating point to the breakdown location over a Blasius boundary layer. The simulation results showed that, the upstream intervention by the finite compliant panel effectively delayed the onset of the incipient turbulent spot by a further distance of Δx = 550, when compared with the rigid wall case results that earlier broke down at X = 1420. This represents an approximately 51% increase in the transition distance measured from the point of wavepacket initiation. Spectral study indicated that the relatively short compliant panel was able to effectively weaken the primary 2-D Tollmien-Schlichting (TS) wave mode, thereby extending the linear regime, so that resultant wavepacket after the panel is dominated by two oblique wave modes and this is the effective strategy of transition delay.
Evolution of wavepacket over short compliant panels in a Blasius boundary layer
(American Physical Society (APS), 65th Annual Meeting Division of Fluid Dynamics (DFD), 2012-11-18) Bori Ige; Yeo, .K. S.; Dou, .H-S.
Compliant surface has been proved in various theoretical studies as a promising tool in delaying transition. This study concerns our recent work carried on the evolution of pulse-initiated disturbance wavepackets over finite-length compliant panels in a Blasius boundary layer by direct numerical simulation (DNS) method. A finite section of the wall was replaced by a tensioned membrane on a damped foundation. By comparing with the rigid wall case, the upstream intervention by a finite compliant panel was found to effectively delay the onset of the incipient turbulent spot – an increase of about 40% in the transition distance with respect to the initiation point was obtained. Transition distance to the occurrence of the incipient turbulent spot was increased further to about 75% relative to a rigid wall when a second compliant panel was introduced. Spectral analysis shows the important role of the fundamental 2D modes in wavepacket evolution and the roles played by compliant panels in transition delay.
Wealth Creation for the Nigerian Youths and Sustainable National Economic Development in Nigeria through Entrepreneurship and Information and Communication Technology
(The Humanities Complex, A.B.U. Zaria. Nigeria, 2012-11-19) IKyembe, Princess; Akuso, Afiniki; Goshie, Rhoda Wusa
Wealth Creation for the Nigerian Youths and Sustainable National Economic Development in Nigeria through Entrepreneurship and Information and Communication Technology As Nigeria marks her fifty-two years of independence, ‘ this giant of Africa’ with a population of over 140 million, is blessed with abundant mineral, material, human, and financial resources. With many of these resources yet untapped, there are numerous challenges confronting the nation which include abject poverty, low standard of living, low rate of economic growth, corruption, insecurity, unemployment, over- dependence on petroleum products and foreign goods and inadequate power supply, among others. The present state of insecurity and incidence of petty and serious crimes in the country has direct bearing on the issue of unemployment among the youths in Nigeria. In order to tackle these problems, certain programs and policies have been adopted by successive governments. These include National Economic Empowerment Development Strategies (NEEDS), Nigeria Bank for Commerce and Industries (NBC), National Directorate of Employment( NDE), National Economic Reconstruction Fund( NERFUND), Poverty Eradication Program, Small- Scale Industry Scheme (SSIS), Structural Adjustment Program (SAP). Operation Feed the Nation (OFN), Green Revolution (GR), State Economic Empowerment Development Strategy (SEED), Local Empowerment Development Strategy (LEEDS), Centre for Entrepreneurship Development (CED), and Youth Enterprise with Innovation in Nigeria (YouWin), among others. This paper therefore examines the role of Entrepreneurship and Information and Communication Technology in wealth creation for the Nigeria youths towards enhancing a sustainable national economic development. Entrepreneurship and Information and Communication Technology can provide a platform for inculcating the necessary skills, innovative abilities and creative capabilities in youths which should prepare them to function well in business and become self- reliant and employers of labor. The paper therefore recommends that government should create enabling environment for foreign investment, transform agricultural sector, provide adequate power supply, encourage indigenous entrepreneurs to expand their markets in order to employ youths, revive textiles and other manufacturing industries and strengthen the existing ones’ and also take proactive measures on the issues of insecurity as well as provide affordable ICT infrastructural facilities to run business centre. If these are properly put in place, the paper stresses an affordable and enabling environment would have been created for both the indigenous and foreign investors to make Nigeria their destination thereby creating more jobs for the teeming youths.
A Comparative Evaluation of the Networks of Three Nigerian Federal Universities for Effective Library Services
(Ghana Library Journal, Ghana, 2013) Abduldayan, F.J.; Oluwade, B.; Oyedum, G.U.
This paper is a comparative evaluation of the networks of three Nigerian federal universities and how such networks can be used to enhance library services. The university networks included in this study are the Federal University of Technology Minna Network (FUTMINNet), University of Jos Network (UNIJOSNet) and University of Lagos Network (UNILAGNet). University of Minna (FUTMIN), established in the 1980s, belongs to the third generation of Nigerian universities; University of Jos (UNIJOS) (established in the 1970s) belongs to the second generation, while University of Lagos (UNILAG) (which was established in the 1960s) belongs to the first generation. Both FUTMIN and UNIJOS are located in North Central geo-political zone of Nigeria while UNILAG is located in the South West zone. The research design employed was the survey method (involving the use of questionnaire, interview, and direct observation) to study the wired and wireless connectivity of the networks of the three universities and compare them against criteria such as network speed, bandwidth, latency, and user response. Structured and semi-structured questionnaires were administered to the network users of each of the three universities, giving a total of 300 questionnaires for the study. The result of the study shows that UNIJOSNet is the fastest while in terms of the wired service, UNILAGNet is the fastest. FUTMINNet is not performing well compared with the UNIJOSNet and UNILAGNet, or not satisfying its users at a satisfactory level. Wireless services of UNIJOSNet and UNILAGNet, which in turn affects the quality of library services offered to users. Wireless services of FUTMINNet do not adequately meet the expectations of users of library services. The paper recommends that the library network services of UNILAGNet has the best performance, while FUTMINNet needs the most improvement. Finally, universities need to enhance their wireless networks by upgrading and expanding the network components and infrastructures of all the networks, especially FUTMINNet.

Evaluation of Sectoral Implementation of the Nigerian National IT Policy
(Social Science Research Network, USA,, 2014) Olatokun, W.M.; Abduldayan, F.J.
The Nigerian National IT policy (USE IT) was formulated in March 2001 with sixteen sectoral application areas and the National Information Technology Development Agency (NITDA) was established as the implementation agency. Out of these sixteen sectoral applications, this study sought to determine the extent of implementation of t he policy in six sectors - health, agriculture, urban and rural development, arts, culture and tourism, national security and law enforcement as well as research and development. Ministries and agencies relevant to each sector were studied and the extent of implementation of the IT policy was evaluated. The study also assessed the newly drafted national ICT Policy to determine whether areas in the current national 11 policy that are yet to be satisfactorily implemented have been taken care of. The implementation of the national 11 policy in health, agriculture, Nigeria Police Force as well as in the research and development sector was adjudged very satisfactory, that of urban and rural development and Nigeria Immigration Service was seen as average; while it was adjudged unsatisfactory in Arts. Culture and Tourism sector. A review of the newly drafted national ICT policy revealed that some of the identified gaps in the current national IT policy had been incorporated to some extent while recommendations were made tor the other areas.

(Benue Journal of Library, Management and Information Science (BJLMIS), Makurdi, 2015) Oyedum, G.U; Chukwu, P.; Abduldayan, F.J.; Abedoh, G.O.
Effective use of e-resources in university libraries is necessary for the academic development of students. This paper, therefore, assessed the relative effect of the available e-resources on undergraduate students' use of university libraries in Niger State. The study also ascertained the e-resources that made the greatest contribution to students' use of the libraries. A survey research design was used for the study, and the study population was 130 undergraduate students from Federal University of Technology, Minna, and Ibrahim Badamasi Babangida University, Lapai. The main instrument used for data collection was a questionnaire. The two libraries, as the study revealed, mainly subscribe to Science Direct for accessibility of e-resources. The study revealed that e-resources such as e-journals, bibliographic databases, e-books, e-databases, e-newspapers, and e-magazines, among others, were available in the university libraries studied. The study also revealed that, of all the available e-resources considered together, e-journals and bibliographic databases made the greatest contributions, which are significant to undergraduate students' use of the university libraries. To enhance the level of use of e-resources and the entire libraries by undergraduate students, the majority of the students indicated the need for the provision of stable network services, followed by an alternative power supply system and the provision of a regulatory body to govern the use of e-resources in the libraries.

(Ahmadu Bello University Library Complex, A.B.U. Zaria. Nigeria, 2015) Gwari, Williams Habiba; Esew, Micheal; Goshie, Rhoda Wusa; Jimada, Aisha
The study aimed at examining the factors that influence the attitude of teacher librarians toward information technology in Kaduna State Secondary Schools. Survey research method was adopted. The study population comprises all the five hundred and four (504) schools. Out of this population two hundred and sixty- four (264) was used as sample size for the study. Questionnaire was the instruments used for data collection. The data collected were presented and analyzed using descriptive statistics. The study found that teacher librarians have positive attitude toward information technology as shown from the respondents who opined that information technology can enhance student learning. The study also found that the possible constraints which tend to have unanimous consensus among the respondents were inadequate trainings on the job, lack of access to technology, poor infrastructure/ social facilities and the epileptic power supply which adversely limit use of the technologies in secondary schools. The inferential analysis showed that the constraints to information technology usage in the secondary schools are positively correlated with the attitude of the teacher librarians towards the information technology use for teaching and learning in the schools. The study concluded that inadequacy of information technology resources, lack of confidence, anxiety, inadequate training, and lack of access to technology, poor infrastructure/ social facilities and epileptic power supply were some of the constraints that significantly influence the teacher librarians’ attitude towards information technology usage in the schools.

Application of Inverse method to Reconstruct the form of Pulse During Impulsive damage to Pipelines
(International Engineering Conference (IEC), 2015) O. A. Olugboji; J. Hale; J. Y. Jiya; C. K. Jack
Petroleum pipelines damages if untimely detected, poses a tremendous challenge to the oil sector of an economy as it causes oil spillage, theft or explosion of the petroleum products while on transit. It is against this backlash an inverse pulse propagation method for reconstructing the form of pulse generated during pipeline defects was devised and presented in this paper. Inverse problem occurs in several branches of science and engineering. It involves the determination of the parameters of a model that describes or explains a set of observed data .This work deals with an inversion technique that was developed to reconstruct the form of a pulse after it has been propagated along a pipe. To test the suitability of the developed technique, a mathematical model was developed. The theoretical model was validated by experiment using a developed pipeline system. The experimental test rig comprises of a flexible hose pipe 23m long and 19mm diameter with four pressure sensors distributed along the pipeline and connected to the data acquisition system. Static and flowing air in the pipeline were use in the experimental test to validate the developed inverse technique model. The inverse method showed a close relationship to the original pulse.

(Civil Engineering and Urban Planning: An International Journal (CiVEJ), 2015-06-01) Ekung, Samuel; Olubajo, Oluseun Olukemi; Ebong, Ubong
The project environment in Nigeria is shifting from traditional practice towards dispersed teams thereby creating the need to understand leadership attributes that lead to successful project outcomes. This study assessed the impact of leadership traits on team performance as correlates of success in construction projects. Like many other management research, the study involve inferential survey. 172 participants drawn from the different professions in the construction industry selected from 42 mega projects completed in the last three years in south-south Nigeria were sampled. Twelve collaborative leadership traits drawn from emotional, managerial competencies were tested against team performance and team spirit stimulants from the literature. Mean item score was used to evaluate relevance of the traits to collaborative working while hypotheses were tested using chi square. While the result of the study is not different from literature, the far reaching implication is that, project team members’ satisfaction translates into successful projects. Project management’s leadership quest to satisfy the project team must be guided towards collaboration. The current result has advance significantly the understanding of team leadership attributes for the research environment and further buttress the need to meet project participants’ mutual objectives for a successful project.

Information Service Provision for the Sustenance of the 21st century Educational Development in Nigeria
(School of Science and Technology Education, Federal University Of Technology Minna, Niger State. Nigeria, 2016-10-04) Ikwe, John Adoga; Goshie, Rhoda Wusa; JImada, Aisha
The increasing important of knowledge as a driver of economic growth; the information and communication revolution; the advent of worldwide labor market and global Socio-political transformations have today brought about a paradigm shift in human capital development in nations of the world. Conceiving and achieving a national aspiration and strategic planning in human resources development is undoubtedly essential to all forms of investment in education which, Nigeria, like most other developing economies are looking forward to. In doing so, Nigeria is also deemed capable of becoming a contributor to scientific and technological advancement. This paper examines the roles played by our educational institutions through provision of relevant information that supports the education for the contemporary sophisticated information society. Libraries and information centers in our institution of learning should address digital literacy, which, some school of thoughts now see as the secret sauce. The paper recommends relevant information provision in our present educational system as this aims at bringing in today’s world for the student because of the flexibility that comes with the contemporary learning through digital objects; social media tools-use should be highly encouraged as they provide a fast means of information sharing between information stakeholders in our educational community; it also recommends an urgent need for eventual update of the education curriculum to integrate the connections in the digital world
Assessment of Safety Provisions on Building Construction Sites in Abuja, Nigeria: Professionals and Workers Perspectives
(Proceedings of the 2nd International Engineering Conference, Federal University of Technology Minna, Nigeria., 2017-01-02) Kolo, D. N.; Yitmen, I.; Tsado, T. Y.; Abdullahi, M.; Yakubu, D. M.
Despite the growth of the building construction sector in Nigeria, the provision of the basic safety materials and facilities to workers remains a challenge. The construction industry is believed to be a pillar of domestic economy in most nations; it is believed to contribute about 2.08% to the GDP of Nigeria. Yet, the rate of non-fatal, fatal injuries and illnesses exceeds that of many other industries, the construction industry has the most fatality rate when compared to other industry sectors. This paper examines the level of provision of the basic safety materials and facilities to workers by contractors in the Nigerian construction industry, the study employed the work study and field survey research method. Structured questionnaire were administered to the Architects, Engineers, Project managers and Contractors as well as the workers engaged in construction. The research exposed the neglect in the provision of safety materials and facilities on the part of the contractors. Scaffolds and shovels where the materials readily provided by the contractors from the list of safety materials provided as recommended by the regulatory authorities. The Institute of safety professionals of Nigeria, Council of registered builders of Nigeria and other statutory government agencies should be more diligent to effectively monitor the activities of building construction contractors in Abuja, Nigeria.

(2nd International Engineering Conference (IEC 2017) Federal University of Technology, Minna, Nigeria, 2017-10-17) Yusuf, .A. W.; Bori Ige; Nasir, .A.
time. Heating, ventilation and air-conditioning (HVAC) play an important role in providing a comfortable condition for occupants in a building. This work concerns air conditioning designs, installations, and performances of some event centres namely: Banquet Hall, Atlantic Event Centre and Nimatoni Event Centre and some offices within the Kwara State Ministry of Water Resources. The impact of the effect of improper design and ventilation on energy efficiency and consumption were also considered. The event centres and offices were studied, by taking both the temperature and relative humidity values for over a period ranging from 75 minutes to 130 minutes, with the use of a device referred to as HOBOware temperature/relative humidity data logger coupled with a HOBOware Software interface installed on a personal computer, for post processing of acquired data. The obtained results of the event centres showed variations in the capacities of the installed air-condition understudied. Also from the results obtained, the cubic meter per minute (cmm) values were found to be 0.0896, 0.2908 and 0.0404 for Banquet hall, Atlantic Event Centre and Nimatoni Event Centre respectively, and these were below the standard recommended value of 0.4245 in the literature.
Development of Screw-Type Briquetting Machine for Municipal Solid Waste
(2nd International Engineering Conference (IEC 2017) Federal University of Technology, Minna, Nigeria, 2017-10-17) Okegbile, .O. J.; Bori Ige; Danlami, .S. M.
The Hydra headed problem of deforestation and Municipal Solid Waste (MSW) Management has bedeviled Nigerian States. Deforestation has put Nigeria on the world’s map as the highest contributor to the world’s deforestation of its primary forest (contributing over 50%), as over 70% of its population depends on firewood and charcoal for cooking and heating. The rising profile of MSW, characterized by inefficient management methods make most Nigerian cities an eye sore, with uncollected waste littering almost every available space, drainages and water channels which poses great danger to human existence. Without alternative energy source available to the growing population, deforestation will continue unabated and in the nearest future Nigeria risk losing all of its forest resource. A Screw-Type briquetting machine was developed that utilizes crushed, combustible MSW to form briquettes to be used for cooking and heating, which is using one problem to fix another. MSW was formulated, crushed and used to form briquette. The briquettes produced burn in similar way to charcoal when compared. This will reduce to the barest minimum, deforestation rate and improve the management of MSW by utilizing as a resource what is termed waste. The developed machine has a throughput capacity of 2605.4Kg/hr and is driven by a 5 Horsepower (5 hp) electric motor.
Empirical Study on Rainfall Patterns and Construction Programme Provisions in Jos, Nigeria
(West African Journal of Building and Road Research. © Nigerian Building and Road Research Institute (NBRRI), Nigerian & Building and Road Research Institute of Council for Scientific and Industrial Research (CSIR-BRRI), Ghana, 2017-11-30) Olubajo, Oluseun Olukemi; Olawuyi, Babatunde James
Weather conditions affect the duration and cost of construction activities, and many companies have neglected the need to consider the exact empirical effect it has on the delivery of construction projects. This prompted an investigation on the precipitation patterns in Jos Metropolis of Plateau State, Nigeria and its effects on the delivery of construction projects. The study evaluated the amount and frequency of yearly precipitation in Jos, and compared it with the provisions made by Builders and Construction Managers in preparing construction programmes and determined its effect on the construction projects delivery. A Mixed design approach was adopted with Rainfall data collected from the Nigerian Meteorological Agency for over a 10 year period as well as from structured questionnaires. The Data was analysed using mean and percentages. The study concluded that the provisions made for idle or rain days in preparation of work programmes for construction projects were in most cases inaccurate and thus affected the performance of the construction projects. The study suggests measures to be adopted by stakeholders towards better project outcome.
Barriers to the Adoption of Building Information Modelling in Nigerian Construction Industry
(Proceedings of the 1st International Civil Engineering Conference, Department of Civil Engineering, Federal University of Technology Minna, Nigeria, 2018-01-02) Kolo, D. N.; Tsado, T. Y.; Bala, A.; Adinoyi, S. A.; Kolo, D. N.
Building Information Modeling (BIM) involves the development and use of computer generated n-D models to simulate, plan, design, construct, adapt, operate, maintain, renovate, and ultimately beneficially deconstruct a building at the end of its life cycle. BIM represents a new paradigm in construction, it encourages the integration of roles of construction stakeholders enabling them to visualize the project to be built and further identifying potential issues that may occur during the operational phase of buildings. This study assessed the barriers to the adoption of BIM in the Nigerian construction industry and further highlighted ways to improve its adoption. A total of 50 questionnaires were administered to construction professionals in Abuja, Nigeria. Forty (40) retrieved questionnaires were analysed using Statistical Package for social Sciences (SPSS 21) and used for this study, it was revealed that there was generally a low awareness on the use of BIM among construction professionals. The major barrier to using BIM was lack of skilled personnel while the major means of ensuring its adoption was Provision of basic BIM infrastructure. These problems can be effectively tackled by increased support from government and construction industry stakeholders for its use; stressing the benefits derivable, training and retraining of key construction professionals taking into consideration peculiarities to the Nigerian construction industry.
