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
A method of preparing cast aluminium alloy �“ graphite particulate composite using uncoated graphite with the addition of 1wt% magnesium to aid wettability was studied. The method consists of introducing and dispersing uncoated but pre-treated graphite particles in aluminium alloy melt and casting the resulting composite melts in suitable moulds. ...

Characterization and concentration of Kurungu Iron ore has been undertaken. Bulk samples were collected from the deposit site located in Kurungu village Ajaokuta Local Government Area of Kogi State, Nigeria. The samples were crushed and pulverized and a representative sample obtained by coning and quartering method. Analysis of the representative s... Continue Reading
This thesis presents the development of a Three Degree of Freedom (3DoF) based outlet fluid temperature controller for Shell and Tube Heat Exchanger (STHX). Shell and Tube Heat Exchangers are classes of heat exchangers being used in industries for heat transfer between fluids. Tracking a setpoint by the STHX is usually a challenging problem, especi...

This study focused on water allocation for different purposes in Tiga dam, using WEAP model to carry out analysis of the hydrological and meteorological information of the study area, with a view to settling the conflict between water allocation of Kano City and major irrigation project. The research commenced with a preliminary site investigation ... Continue Reading
The lack of information on bus travel time in Makurdi metropolis to enable trip makers plan for journeys is seen as a challenge in recent times. This study developed a multiple linear regression model for predicting bus travel time along bus routes within the metropolis and this was achieved throughmeasurement of the physical characteristics of the...

In this research, experimental research was carried out to assess the flexural and shear capacities of RC beams strengthened with different amount of carbon fibre reinforced polymer laminates at the tension face and U-strips. Twelve rectangular RC beams of cross-sectional dimension 150x150x750mm were cast and three were un-strengthened and used as ... Continue Reading
The influence of tungsten inert gas (TIG) welding process parameters on the microstructural features and mechanical properties (hardness and tensile strength) of AISI430 ferritic stainless steel (FSS) welds based on the central composite design (CCD) approach, was investigated. The process parameters considered in this study include; the welding cu... Continue Reading
Records of flooding are increasing due to heavy storm which tend to filled most of the water bodies, thereby overflowing onto the land, causing damages and endangering the lives people. Flood also occur due to other factors such dam break, overflowing rivers etc. Most of this event occur with inadequate capacity of reservoirs, channels, drainages e... Continue Reading
In the calibration of partial safety factor of steel reinforcement bars conducted in this study, necessary parameters (i.e. steel diameter, area, yield strength, ultimate strength, and elongation) needed for the calibration were obtained from the steel testing laboratory, Department of Civil Engineering, Ahmadu Bello University Zaria. The test resu... Continue Reading
Vegetable oils need to be chemically modified before being used for biolubricant production for internal combustion engines applications. One of the most effective chemical modifications for vegetable oils is epoxidation of its double bonds. In this work, Crude Jatropha oil (CJO) was epoxidized using peracid generated in-situ by the reaction of for... Continue Reading
Aromatization is an important process for catalytic conversion of light alkanes to aromatics which are essential feedstocks to petrochemical industries. A number of catalysts have been used for this transformation among which Zn/ZSM-5 emerged so far best owing to its good dehydrogenating activity, lower cost and environmental friendliness. Compared... Continue Reading
The necessity to source clean energy and contain CO2 emissions has brought about a global interest in the use of biomass as an environmental friendly renewable energy route. One of the drawbacks in the conversion of biomass to energy via pyrolysis/gasification is the liberation of CO2 from the syngas.This study was carried out in a two- stage catal... Continue Reading
A Carbon fiber-reinforced polymer (CFRP) has emerged as promising material for rehabilitation of existing reinforced concrete structures. However, one of the major concerns of using this material is its high cost. In this research, a classical optimization technique was employed to optimize the thickness of Carbon Fibre Reinforced Polymer material ... Continue Reading
