ABSTRACT Due to global competition, many organizations are coming up with ways of sharpening their competitive edge. This has been achieved through cost leadership, differentiation of goods and services and lastly, through quick response to the needs of the customers. To respond to these market requirements, manufacturers are using high-tech equipment. They are also adopting new material control methods such as Just-In-Time philosophy. Set-up costs are also being minimized to a minimum. All ...
Biodiesel is a clean-burning alternative fuel produced from renewable resources. However, it is susceptible to oxidative degradation due to autoxidation in the presence of oxygen, which hinders its widespread use. Antioxidant addition is a prospective solution to this problem. It is expected that antioxidants may affect the clean-burning characteristic of biodiesel. The aim of current study is to investigate the feasibility of biodiesel-diesel blended fuel of (30%, 35% and 40% biodiesel)...
ABSTRACT The Hydrogen sulfide gas released from the geothermal operations has a potential impact on the health of the workers and the community living within the vicinity and also the geothermal equipment. Similarly, this gas is a toxic pollutant when released into the atmosphere. Additionally, this gas is corrosive to metal-based materials including brass and iron when dissolved in water. In this regard, there is need to manage the concentrations of hydrogen sulfide in the atmosphere at acc...
Because of the significant importance of the gas-turbine engines as it is the core of the aircraft, the engine health status should be tested periodically. Testing methodologies are needed to conduct the engine tests required as a part of airworthiness certification. In this project a data acquisition system was developed as a gas turbine engine testing system. This system was developed to monitor the engine parameters to determine its condition and to control the engine starting compo...
ABSTRACT In real situation the physical earth is in three Dimension (3D), a two dimension (2D) and one dimension (1D) earth models may not therefore explicitly explain or characterize the 3-D Earth in all situations. This is a simple and apparent reason why one needs a higher dimensional interpretation of Magnetotelluric (MT) resistivity data in modelling geothermal reservoirs. 2D MT interpretation is frequently applied in geothermal assessment and in many cases has effectively provided accu...
Generally the anti-theft security system becomes very important these days according to the high rate recording of the theft crimes cases around the world. In this project the vehicles security system type will be the focus of the study. The main objective of this vehicle’s anti-Theft Security System project is to design a smart security system to provide the highest level of protection to the owners of the vehicles or the authorized persons for unauthorized usage objects. In the resu...
Abstract The basic goal of manufacturing industries is tomaximize profitability in order be competitive and stay in the market. This is mainly achievedby producing products at low cost to maximize profits. However,low productivity has been the major problem facing most manufacturing companies just like DMKL. Two major sections that are affected by low productivity in DMKL processing plant are Labeling and Parking section. Productivity in these sections stand at an average of 50% the rated ca...
ABSTRACT This research work is aimed at using the energy and exergy analysis with thermodynamic data to suggest improvements in the performance of steam and gas turbine power plants. In this regard, specific data from Egbin steam power plant and Geregu I gas turbine power plant were used for the analysis. In the analysis, scientific tools such as Engineering Equation Solver (EES) programme with built-in functions for most thermodynamic and transport properties was used to calculate the entha...
ABSTRACT This research work on “Modelling and Simulation of Leakage-Induced Pressure drops along oil and gas pipelines tends to develop flow equations that can detect and localize leakages in oil and gas pipelines by modifying the Darcy-weisbach equation for liquid/oil flow, and the Panhandle B equation for natural gas flow in pipelines. These modified equations were simulated using matlab to show how flow rate values for the oil and gas pipelines vary when; the pipeline is working at full...
ABSTRACT This research work focused on the use of an hybrid RANS-LES turbulence model in simulating and checking the drag performance characteristics of an aerodynamic vehicle. The Spalart-Allmaras shear stress transport (SST)- Scale Adaptive Simulation (SAS) Turbulence model was selected for use, and with the help of OpenFOAM Finite Volume Computational Fluid Dynamic Solver the simulation algorithm was set and carried out in a total time step of 4000. Convergence was achieved under the stip...
ABSTRACT Performance analysis of a model pulverized coal combustion system is undertaken. The system consists of a hopper, screw conveyor, blower, electric motor, among others. The design and construction of the system focused on the following procedures in this work: The outlet of the pulverized coal from the silo opens directly into the receiving hopper of the screw conveyor. The drive of the blower is connected to the drive of the screw conveyor via bearings, pulleys, belt and gears. This ...
Abstract A Mobile Ad-hoc Data Network (MADNET) is a self-configuring, infrastructure-less network of mobile devices (nodes) where nodes communicate with each other using multi-hop wireless links. Node failures and arbitrary movement of nodes at higher node velocity break the routes and lead to the frequent operation of rebuilding routes that consume lots of the network resources and the energy of nodes. This study, analyses the impact of node velocity on performance of two MADNET Transport p...
ABSTRACT This work analysed the performance of an automatic control system for the online blending of petrol with corrosion inhibitor in the direct, continuous electronic fuel injection automobile engine. The automatic control system was designed by superimposing a feedforward control system on a feedback control system. The design of the automatic control system was analysed by the method of direct substitution. The governing equations used in analysing the blending process, as well as the ...
ABSTRACT Environmental pollution with petroleum and petrochemical products has been recognized as one of the most important and serious challenges facing environment engineers. Disposal from mechanic sites, accidental leakages from petroleum carrying ships, vandalization of pipelines, have all contributed to the current common oil pollution in Nigeria today. The currently used physical and chemical remediation are effective for the degradation of petroleum products but the affected medium lo...
ABSTRACT Data storage and retrieval are at the centre of today’s applications. Currently, no organization can effectively carry on its activities without one form of database or the other. Indeed, one of the key challenges of information technology organizations is how to ensure quality and reliable database administration. Consequently, if the database and the server that support the applications are unavailable it could lead to considerable costs in terms of efficiency, loss of revenue a...
