Queuing theory as a tool for optimising patients flow and resources utilisation in the female section of the OPD at Yusuf Dantsoho memorial hospital Kaduna, the study was conducted for a period of 5 days. Simple queuing theory calculations were done using the data collected in the evaluation of the performance characteristics of the system, i.e. th... Continue Reading
This research developed a license plate and classification scheme using deep learning architecture which utilized transfer learning using pre-trained Convolutional Neural Network (CNN). The developed scheme used images obtained from Caltech dataset, Peking University VehicleID (PKU VehicleID) dataset and a developed dataset of vehicle licence plate... Continue Reading
This research developed a hybrid forecasting technique that integrates Cat Swarm Optimization Clustering (CSO-C) and Particle Swarm Optimization (PSO) algorithms with Fuzzy Time Series (FTS) forecasting model. Cat Swarm Optimization Clustering (CSO-C) which is an algorithm for data classification is adopted at the fuzzification stage to objectively... Continue Reading
This work aimed at designing and implementation of Shunt Active Power Filter (SAPF) for power quality improvement through harmonic reduction. The current harmonics are being caused by nonlinear characteristic of power electronics based equipments which increase power losses and in turn reduce power quality. This work employed a three phase three wi... Continue Reading
This study assessed the impact of open dumpsites on the quality of groundwater within the vicinity of solid waste dumpsites in Maiduguri. The problem of rapid urbanization and poor waste management has resulted in an increased of hand dug wells with some located within the premises of an open dumpsites. The mean percentage composition of solid wast... Continue Reading
This research work presents the development of branch current based state estimation for Non-Technical Losses (NTLs) Detection and Localization. The use of weighted least square (WLS) state estimation for the evaluation of branch current of a network during theft is considered. In order to confirm the presence of theft in a network, current measure... Continue Reading
This research developed a distributed big data fusion architecture for machine to machine communication using ensemble learning. This is implemented to mitigate the challenges that characterize centralized big data fusion architecture commonly adopted through the use of Hadoop MapReduce platform. These challenges include bandwidth consumption, late... Continue Reading
It has being observed over time that there are problems associated with the quality of designs and execution of jobs within the Building Services Sector of the Engineering Industry. The sector is an important aspect of Engineering Practice in Nigeria and its performance can only be measured by the quality of its output which include good engineerin... Continue Reading
This study has evaluated the effectiveness of metallic materials as chill in sand casting of aluminium alloy. Four plates of dimension 165mm x 80mm x10mm were cast using sand mould. Steel, copper and brass chills in form of cylindrical bar of geometry 7mm in diameter and 50mm long were inserted, side by side at regular intervals of 30mm in each san... Continue Reading
This research work presents the development of a privacy aided trust routing model using social similarity in an Opportunistic Network (OppNet). OppNet is a delay tolerant network where link is highly unpredictable. It is an ideal solution in situations where the deployment of wired and conventional wireless networks is difficult or practically imp... Continue Reading
The effectiveness and sensitivity of vertically curved concrete flyover bridge (VCCFB) profile is presented. Modal analysis was conducted on three VCCFB models; one for a profile achieved using horizontal beams, profile achieved using slightly curved beams and a profile achieved using combination of straight and curved beams. Twelve vibration mode ... Continue Reading
Four timber species (Strombosia pustulata, Macrocarpa biquertii, Entandrophragma cylindricum and Nauclea diderichii) were laminated with aluminium sheets of varying thicknesses.Axial and flexural loads were applied to the composite columns to determine their behaviour under such loadings. Finite element analysis was carried out in Abaqus/CAE 6.10 (... Continue Reading
The methodology of the experiment involves three main stages. The first part describes the synthesis of the PF (novolac) resins. Novolac (resins) were prepared with an excess of phenol over formaldehyde under acidic conditions. PF molar ratio were varied from 1P:2F to 1P:8F. The structure of the PF was determined using FT-IR techniques. The prepara... Continue Reading
This dissertation presents the development of an improved application specific tunnelling protocol selection scheme (iASTPSS) for site-to-site virtual private network (VPN). The aim is to develop an improved tunnelling protocol selection scheme for site to site VPN that is application specific, requiring security, bandwidth, and time sensitivity as... Continue Reading
This dissertation presents the development of an Internet Protocol (IP) traceback scheme for the detection of a denial of service (DoS) attack source base on shark smell optimization algorithm (SSOA). Detection of the source of DoS attack is very important due to the serious damages the attack do cause and the need to bring the perpetrators to just... Continue Reading
