This research investigated image recognition frameworks on datasets of visible-light and infrared (IR) imagery using deep convolutional neural networks (CNN). This is due to their recent success on a variety of problems including computer vision which often surpassed the state of the art methods. Three deep learning based object recognition approac...

This study is aimed at the development of a mechanism for black hole attack mitigation in Wireless Sensor Network (WSN) using a modified Bacterial Foraging Optimization Algorithm (BFOA). A total of 200 randomly generated bacterial sensor nodes with a communication range of 20m were deployed in a 100mx100m network coverage area, consisting of four b... Continue Reading
Modern campus networks are designed for high-speed service with the capacity to handle many organization's bandwidth requirements, support data applications such as electronic-mail, web and files sharing services. These networks sometime lack the capacity to guarantee quality of service for voice, video and other interactive applications due to ban... Continue Reading
The Sokoto Basin,(the South-Eastern sectorof Iullemmeden basin), located in Nigeria, consists of an aquifer system which is bi-layered with cretaceous Continental Intercalaire (CI) sedimentary deposit at the bottom,(Sokoto Group, Rima Group, Gundumi-Illo Formation), by Continental Terminal (CT) Formation(Gwandu Formation) and surface water. The wat... Continue Reading
This study determined the effects of copper addition and section thickness on some mechanical properties and the morphology of graphite flakes in grey cast iron. It also characterised the microstructure of grey cast iron evolved in the investigation. This was of the view of ensuring that automotive industry designers are able to make informed choic...

This study is to investigate the effects of Expanded Polystyrene (EPS) as a partial replacement for coarse aggregates at 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50% at elevated temperatures of Room Temperature (280C), 200?, 400?, 600?, and 800? for the duration of 2 hrs each. Compressive strength and flexural strength were carried out o... Continue Reading
Single stage alkali-catalyzed transesterification of vegetable oils having free fatty acid (FFA) content above 0.5% promotes saponification which lowers the biodiesel yield by deactivating the catalyst. A strong solid base KF/Eggshell catalyst, which is capable of circumventing saponification while producing biodiesel in a single stage from neem oi... Continue Reading
The challenges of continual depletion, economic crisis and environmental issues of the petroleum fuels have attracted the scientists’ interest to seek for alternatives to fossil fuels.Biodiesel is the alternative to petrol diesel because; it has similar physicochemical properties to petrol diesel. However, biodiesel has not been competing favoura... Continue Reading
The physicochemical and bacteriological qualities of effluents from WUPA Sewage Treatment Plant, Abuja were determined within the duration of twelve weeks. Grab method of wastewater sampling was used while sampling for the analysis. The sampling and analysis were carried out between May and September, 2015. Samples were collected at the inlet to th...

One of the requirements for enabling two nodes to communicate through a network is the existence of a fully connected path between them. However, there are scenarios in wireless networks where this is not the case and yet nodes still need to communicate freely. Despite concerted efforts to resolve this problem of unconnected wireless nodes trying t... Continue Reading
Admission Control is a vital component for end-to-end Quality of Service (QoS) delivery in a packet flow network. It is more effective when implemented at the edge of the network. The edge of a mobile network is dominated withmultiplexer which either uses Synchronous Digital Hierarchy (SDH) or Wavelength Division Multiplexing (WDM) for transport. T... Continue Reading
The physicochcmical characteristics of water in rivers of middle Galma basin were monitored at twelve stations during a period of two years. These stations were located at various points on river Shika, river Kubanni and river Galma. The parameters measured were pH, electrical conductivity, temperature, total dissolved solids, nitrates, phosphates,... Continue Reading
Over the years, oil spillage has been precarious and most of the time unpredictable. It misbalances the ecosystem directly and indirectly on a rampage scheme, claiming thousands of marine lives; animals and plants and in some cases humans too. Whenever it occurs, the oil being less dense than water floats on it, which simply means that there is no ... Continue Reading
This research work utilized the silica obtained from locally sourced kaolin (from Kankara in Katsina State) to produce zeolite grade sodium silicate as a raw material for the preparation ofsilica sol for ZSM-5 synthesis. The work also involved development of sodium silicate pilot plant. Of the various dealumination routes considered, double dealumi... Continue Reading
