A Comparative Analysis of Grillage Method and Beam line Analysis of a Reinforced Concrete Waffle Brifge Deck
(Nigeria Journal of Engineering and Applied Sciences (NJEAS), 2022-01-23) Adamu, H. N.; Abbas, B. A.; Abubakar, M.; Yusuf, A.; Kolo, D. N.; Shehu, M.
The analysis of reinforced concrete waffle bridge deck using Chanchaga bridge as a case study was carried out with the aid of computer program written in MATLAB. The bridge deck which is a beam bridge was idealized to be a waffle slab. A mathematical model of the bridge was developed using the method of grillages because very complex shapes of problem domain with prescribed conditions can be handled easily using the method. The bridge deck was modelled as interconnection of grid elements. The analysis was carried out using direct stiffness matrix method. The nodal displacements and the resulting static internal forces; shear forces, bending moments and twisting moments of each grid element were determined using the matrix. The results obtained using the method of grillages were then compared with beam line analysis and the former method gave a 10% decrease in forces which will result in the reduction of overall design and materials by 10%.
Agriculture by-product: A Source for the Production of Biogas
(Asian Journal of Engineering and Technology, 2015-04) Eterigho, Elizabeth Jumoke; Farrow T. S.
Agricultural by-products, rice husk and maize bran were used anaerobically in this study to produce biogas. The suitability of these substrates as source of biogas and comparative study of the two substrates were investigated. Various analyses were carried out to determine the ash content, moisture content, volatile solids and fixed carbon content present in each substrate. The biogas produced was analysed using a gas chromatograph and was found to contain oxygen, nitrogen and methane in various proportions. From the results of the analyses, rice husk produced a larger volume of gas than the maize bran, though the maize bran's gas has a higher content of methane than that of rice husk (about 60.90%). The experiment was carried out under mesophilic temperature range and a pH of 6.2 - 7.6

(Nigerian Journal of Technological Research (NJTR), 2013) Eterigho, Elizabeth Jumoke; Lee, J. G. M.; Harvey, A. P.
Sulphated zirconia (SZ) was synthesized using two different methods with the same molar ratio (1:6) of reactants: (1) the direct mixing of ZrOCl.8H20 and (NH4),SO4, designated as SZ,; and (2) via the conventional wet-precipitation method with a molar ratio of l:6 rather than the conventional 15 ml H2SO4 to Ig of Zr(OH)4, denoted by (SZ,). The catalysts physiochemical properties were precisely characterized by FTIR, SEM, X-ray diffraction, EDX, XPS, and Py-DRIFTS techniques. The two methods of preparation with same molar ratio of sulphating agents led to sulphated zirconia that exhibited different morphological and structural properties in terms of specific surface areas, thermal stability, acid sites, and surface sulphate. The catalysts activity was tested in thermocatalytic cracking of triglyceride; a direct conversion process for fatty acid methyl esters (biodiesel). The SZ not only exhibited higher conversion of triglycerides but higher fatty acid methyl esters (FAMEs) yield of approximately 59% after 3h as compared to SZ, (32%). In addition, the sulphated zirconia, SZ, was selective towards unsaturated esters whereas SZ, was selective towards saturated esters.
An Investigation of Partial Shading Effects on Solar Photovoltaic Module Performance Using Infrared Thermography
(4th International Engineering Conference (IEC 2022) Federal University of Technology, Minna, Nigeria, 2023-03-21) Jaji, .U. F.; Bori Ige
Partial shading is detrimental to the performance of a solar PV module. This is because it not only reduces the current and voltage of the module which leads to power loss in the module but may also lead to the formation of hotspots. This work presents an investigation carried out on the cross-comparison of two different PV modules subjected to the same ambient conditions in a tropical hot climatic region, to observe the effects of partial shading on them and if hotspots are formed, determine if they are heightened by the climatic condition of the environment. Different shading patterns and shading due to partial obstruction of direct radiation were considered. Shading was achieved using opaque shading sheets. The results of the experiment showed that the efficiency or performance of these modules is dependent on the type and direction of shading. This implies that as the percentage of shading increases, there is a decrease in power output and ultimately its efficiency. Also, thermal images obtained showed that asides temperature difference between the modules, hotspots formed on the test modules were not magnified by climatic conditions. The Infrared image indicated the likelihood of an internal defect in the control module. Considering the emergence of new solar technologies to improve its efficiency, it’s recommended that a similar investigation under real outdoor conditions be carried out on Perovskite solar cells. Results of the outcome of the findings should be compared to those of the silicon crystalline modules, to determine which solar technologies perform better.

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.

(Nigerian Institution of Mechanical Engineers (NiMeCHE), 2020-10-20) Irekeola, .B. J.; Bori Ige; Adedipe, .O.; Babawuya, .A.
For many years, Nigeria has been facing energy crisis that is hampering her economic development. Energy is one of the key fundamentals for economic development and it is also fundamental to all human activities in this era. In this study, renewable energy potentials in Sokoto and Katsina states were analyzed respectively. Data covering a period of ten years (2007 - 2017) were obtained from the Nigerian Meteorological Agency (NIMET), Abuja, for monthly average daily solar radiation, maximum and minimum temperatures for the two states under investigations. The data were subjected to statistical analysis such as normality test, to examine whether the data is normally distributed using standardized coefficient of skewness, and kurtosis using a 250 Watts by 1.68m square solar panel; the results show that the solar radiations are negatively skewed by a value of -0.6 and -0.43, which makes the two states more reliable during the dry season of the year. The two states have a kurtosis of -1.17 and -1.38 indicating that the bell shape is slightly flatten than normal distribution shape. A linear regression model was also developed to predict the trends in solar radiation for the study area. The results show that Katsina state has a higher reliability (0.86) for solar energy potentials than Sokoto state (0.72).
Analysis of Statically Determinate Trusses using Exact Method (Joint Resolution Method) and Matrix Stiffness Method
(USEP: Journal of Research Information in Civil Engineering, 2017) Abdullahi, A.; Yusuf, I. T.; Abubakar, Mahmud; Aminulai, H. O.; Yusuf, A.; Alhaji, B.
Matrix Stiffness Method (MSM) as a tool for static analysis of structures is premised on the principle of Finite Element Method (FEM), which in itself is a numerical/approximate method capable of giving only approximate results. However, Joint Resolution Method (JRM) is one of the most popular classical/exact methods of static analysis capable of giving exact results. This paper presents an analysis of a statically determinate 2-D truss using Exact/Joint Resolution Method (JRM) and Matric Stiffness Method (MSM) to ascertain the validity of the latter against the former. In the JRM, the support reactions and internal member forces were obtained from considerations of the equilibrium conditions of the entire truss and isolated joints respectively. On the other hand, a computer program was written in MATLAB 7.8.0 (R2009a) based on the principles of MSM for ease of computation and increased accuracy to solve for member forces and reactions of the same truss. The element properties were obtained and employed to calculate the element stiffness matrices, these were then assembled into the global stiffness matrix, from which the unknown displacements, member forces and support reactions were calculated. The results obtained from using both JRM and MSM were found to be exactly the same or very close, with percentage errors ranging between 0% and 3%. Hence MSM results as compared to JRM have 97% accuracy and above, and can therefore be relied upon.

APPLICATION OF ARTIFICIAL INTELLIGENCE FOR PREDICTING THE COMPRESSIVE STRENGTH OF CONCRETE USING NATURAL AGGREGATE
(2nd Annual Seminar of The Nigerian Society of Engineers Bida Branch:, 2023-10-05) Okafor A.; YUSUF, Abdulazeez; Abbas B. A.; Kolo D. N.; Adelasoye J.
This seminar presentation explored the application of various artificial intelligence techniques such as Artificial Neural network (ANN), Adaptive Neuro-Fuzzy Inference System (ANFIS) and Multiple Linear Regression (MLR) for predicting the compressive strength of concrete using natural aggregates. Twenty-seven different experimental data points which was augmented to 180 data points was used in the study. The ANN, ANFIS and MLR models were developed, trained, tested and validated with the augmented data using MATLAB software. Statistical evaluators like the R2, MSE and the RMSE was used to evaluate the algorithm with the strongest predictive capability. The results obtained from the analysis revealed distinct performance variations among the three AI models studied. Both the ANN and ANFIS models consistently demonstrated superior predictive capabilities compared to the MLR model. The ANN gave R2 of 1, MSE of 8.66e-26 and RMSE 2.94e-13, the ANFIS gave R2 values of 1, MSE of 0.00033 and RMSE of 0.0183 while the MLR reported R2 values of 0.1243, MSE of 85.93 and RMSE of 9.27. The ANN model was adjudged to be the best prediction model for concrete containing natural aggregate based on the performance metrics.
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.
Artificial Intelligence and Structural Reliability Analysis in Nigeria: A Review
(Department of Civil Engineering, FUT Minna, 2024-12-12) Olorunpomi, M. D; Kolo, D. N.; Abdullahi, A.; Agbese, E. O.
Reliability is a probabilistic measure of structural safety. In Structural Reliability Analysis (SRA), both loads and resistances are modelled as probabilistic variables, and the failure of structure occurs when the total applied load is larger than the total resistance of the structure. This review presents the recent advances in using Artificial Intelligence (AI) in SRA; it explores the application of Artificial Intelligence (AI) in assessing the structural reliability of structures, particularly focusing on the integration of machine learning models, predictive analytics, and data-driven approaches. AI-based tools can enhance accuracy, speed, and efficiency in structural assessments, offering a potential solution to Nigeria's infrastructure challenges. Machine learning-based techniques have been introduced to SRA problems to deal with its huge computational cost and increase accuracy. ANNs and SVMs are two popularly used tools in the ML-based SRA literature. They have been widely used for the SRA because of their adaptability to different well-known reliability calculation methods such as MCS, FORM, and SORM. While these technologies have been successfully implemented in other parts of the world, its application in Nigeria faces challenges related to data availability, infrastructure, and expertise. Nonetheless, with the increasing adoption of digital technologies in Nigeria’s construction industry, AI offers a compelling opportunity for improving the safety and sustainability of concrete structures.
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.
Assessment of the Compressive Strength of Concrete Produced with Fine Aggregate from Different Locations in Minna
(3rd International Engineering Conference (IEC 2019) Federal University of Technology, Minna, Nigeria, 2019) Aminulai, H. O.; Abdullahi, A.; Abubakar, Mahmud; Abdulrahman, H. S.; Alhaji, B.; Joseph, O. F; Aliyu, S. Y
The construction industry in Nigeria has been witnessing serious collapse of buildings resulting from the qualities of materials used in their construction. This continuous collapse necessitates the need to investigate some of the materials used in the production of the building components in order to ascertain their appropriateness. This research thus investigates the compressive strength of concrete produced using fine aggregate from different locations in Minna. Fine aggregates were obtained from Chanchaga, Maikunkele, Bosso, Lapai Gwari and Garatu areas of Minna and subjected to series of tests namely: sieve analysis, Specific gravity, bulk density, moisture content, and water absorption. Concrete samples were produced using the mix ratio 1:2:4 and the water/cement ratio of 0.6. These samples were subjected to both the slump test and compressive strength test. For each of the fine aggregates, nine cubes of concrete (150mm x 150mm x 150mm) were cast, cured and tested at 7, 14 and 28 days. The results obtained for the mean compressive strength of the concrete produced shows that they all have mean strength greater than 20N/mm2 with fine aggregate from Chanchage having the highest mean of 25.17N/mm2 at 28days of curing. Thus all the fine aggregates could be used in the production of structural lightweight concrete but for structures that require higher strength, the fine aggregate from Chanchaga is recommended
ASSESSMENT OF THE HYGROTHERMAL PROPERTIES OF MORTAR USING QUARRY DUST
(1st International Civil Engineering Conference (ICEC 2018), 2018-09-22) Okafor A.; YUSUF, Abdulazeez; Abdullahi A.
Assessment of the hygrothermal properties of mortar using quarry dust as fine aggregate was studied. The material used include Ordinary Portland Cement, water and quarry dust. Preliminary test such as particle size distribution, bulk density, moisture content and specific gravity were conducted on the aggregate in accordance to BS EN 1097:6. The mortar was prepared using a mix ratio of 1.4 and cured for 28 days. Water absorption, porosity and sorptivity test were the properties measured. Fineness modulus of 2.94, specific gravity of 2.42 and water absorption of 1.4% was recorded. The porosity and sorptivity were within the limit set by standard but the water absorption capacity was slightly higher that the limit specified. The study concluded that quarry dust can be used in the production of structural mortar.

(2018-09-22) Mohammed T.A.; YUSUF, Abdulazeez; Abdullahi A.
The study was carried out to assess the properties of High-strength concrete made using Quarry dust as Fine aggregate. Preliminary tests were carried out on the aggregates to determine their suitability for use in High- strength concrete. The aggregates were well graded and other properties met the requirements of aggregates to be used for High-strength concrete. Superplasticizer and Rice husk were used as chemical and mineral additives to improve the workability and other properties of the concrete. Based on the properties of the aggregates, a mix ratio of 0.23:0.51:0.044:1.05:0.7:0.2, representing cement: fine aggregate: coarse aggregate: superplasticizer: water: rice husk was used. Concrete cubes of 100x100x100 mm were cast, cured and the 28-day compressive strength determined. An average 28-day compressive strength of 63 N/mm2 was obtained. This can be categorized as class I high strength concrete and is applicable in the construction of high rise buildings. The Study therefore concludes that quarry dust can be used as total replacement for fine river sand in high strength concrete production.
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.
Bio-electrochemical response to selected experimental treatments of a soil-type microbial fuel cell for sustainable bioelectricity generation
(International conference on sustainable development and technology-Elsevier, 2021-11-02) Simeon, Meshack Imologie; Alfons, R. Weig; Freitag Ruth
The need to protect the environment has triggered a search for alternative and sustainable energies to replace or drastically reduce the world's dependence on fossil fuels. Bio-electrochemical systems (BES) are among the leading research topics in alternative energy sources due to their multi-functional potential. However, their low energy production rate limits their application in the real world. Therefore, architectural and biological optimization is required to take BES beyond laboratory-scale experiments. In this study, we investigated the interactive influence of electrode materials, electrode spacing, and frequent substrate feeding on microbial community diversity and electrochemical behavior of a soil BES for sustainable power generation. Two electrode materials (carbon felt (CF) and stainless steel/epoxy/carbon black composite (SEC) were tested in a soil microbial fuel cell (S-MFC) under three levels of electrode spacings (2, 5, and 8 cm) and treatment frequencies (4, 6, and 8 days). After 30 days of operation, all MFCs achieved an Open-circuit voltage of 782+12.2 mV regardless of the treatment. However, the maximum power of the CF-MFCs was 12.19 + 1.6 mW/m2 at a current of 15.8 mA/m2, while the SEC-MFCs produced 125.69 + 9.3 mW/m2 at a current of 277.4 + 19.3 mA/m2 under the same experimental conditions. The overall best and sustainable performance (145.3 + 8.03 mW/m2) during the 66-day operating period was obtained with SEC-MFC at 5 cm electrode spacing and treatment frequency of 8 days. 16S rDNA gene amplicon sequencing of DNA samples from the anode, cathode, and point of maximum power (MPP) revealed complex microbial diversity that showed significant compositional changes at the electrodes and MPP. The results showed that too small or too large electrode spacing and frequent substrate loading were not suitable for the MFC configuration in this study, and the electrode material had the greatest impact on S-MFC performance.
Biogas Production from Rumen, Municipal and Co-Digested Substrates: An Opportunity for Small and Medium Scale Entrepreneurs (SME)
(APWEN International conference (a division of NSE) Kano, 2017-09) Habibu, Uthman; Musa, Michael Adeiza; Eterigho, E. J.
Comparative study of anaerobic digestion of Rumen, municipal w a s t e and co-digested feedstock was investigated. 10kg each of rumen, municipal waste and co-digested feedstock each was used in a 30 litres anaerobic digester. The digester was loaded batch wise for 3 0 retention day runs up to 80% volume of the digester nominal volume. The cumulative biogas production was recorded as 181900, 217350 and 180250 ml/g VS-1 respectively. Methane composition of the various biogas was 56.42, 55.81 and 58.820 % untreated biogas samples. The treated s c r u b b e d water produced a burning gas with m e t h a n e composition 84.08,51.54 and 95.518 % respectively for the feedstock. Co-digested s u b s t r a t e d o e s n o t actually have any significant effect on production and composition of the gas produce. Since waste raise a major environmental concern, these simple steps could be exploited by small and m e d i u m scale entrepreneurs (SME), an alternative to convert waste into fuel that c a n be tremendously useful as renewable fuel source especially for domestic and industrial use.
Catalytic Cracking of Tryglyceride by Sulphated Zirconia for Fatty Aciud Methyl Ester with High Selectivity
(American Institute of Chemical Engineers (AIChE) Annaul Conference meeting, Minneapolis, MN, United State, 2010-07-21) Eterigho, Elizabeth Jumoke; Lee, Jon G. M.; Harvey, Adam P.
Conventional wet-precipitation method was used to synthesis sulphated zirconia using two different molar ratios of sulphating agents. (1) the first was using a molar ratio of 1: 45 of ZrOCl2.8H20 impregnated with 1 M H2SO4, (wp) and (2) a molar ratio of 1: 6 was used for the modified conventional wet-precipitation method, (wp). The properties of both catalysts were examined by various techniques: EDX, XPS, FTIR, SEM, XRDP, Py-DRIFTS and BET nitrogen adsorption techniques. The variation in the molar ratio of the sulphating agent used during preparation led to sulphated zirconia that exhibited different properties in terms of specific surface areas, acid sites, thermal stability and surface sulphate. Both catalysts were catalytically active for triglycerides cracking for fatty acid methyl esters in a thermocatalytic reaction. The SZ not only exhibited higher conversion of triglycerides but higher FAMEs yield, approximately 50% after 3 h, as compared to SZ2 (39%). Interestingly, SZ1 was selective towards unsaturated esters whereas SZ2 was towards saturated esters.

(2nd International Civil Engineering Conference (ICEC 2020), 2020-08-29) Asogwa E.O; Umar B.M; Adesiji A.R; Gbadebo A.O; Mangey J.A
Random samples of bottled drinking water in Minna metropolis were collected and analyzed using water quality index. This study was carried out to characterize the bottled drinking water using water quality index so as to assess the suitability of bottled drinking water from different sources with the study area. Ten samples were purchased at the sources of production for four consecutive months of April, May, June and July 2019 and analyzed for pH, Calcium, Total Hardness, Total Alkalinity, Chlorides, Magnesium, Sulphate, Nitrate, Iron, and Manganese. The results show that all the parameters analysed were all within the permissible limits of World Health Organization. The results obtained for the WQI from the different bottled water products were found to be varied from 4.96 to 21.65. These results indicate that the all the bottled water samples analyzed are safe for human consumption and for other domestic purposes. Effort should, however, be made to ensure the sustainability of the current method of bottled water production within the metropolis.
