ABSTRACT Traditional power grids are now transformed into Smart Grids (SGs) in order to solve the problems of energy wastage, energy control, uni-directional flow of information, growing energy demand, reliability, measurement and security. Smart grids increase the automation, coordination and connectivity between these electricity suppliers, electricity users and networks used in local distribution tasks and long distance transmission. Smart Grids offer bi-directional energy flow between ele...
ABSTRACT A traffic light also known as a traffic signal, stop light and go light, robot or semaphore is a signally device positioned at four (cross) junction, pedestrian crossing or other locations in other to indicate when it is safe to drive or walk using a universal color code ( and in precise sequence for those that are color blind). Traffic light system operate on a turning mechanism that changes the light after a given interval of 7-120 seconds depending on the traffic congestion on t...
ABSTRACT This research study the concentration of certain toxic metals in street dust along road construction site and relate the finding to the standard control measure to determine the extent to which environmental uncontrolled process can pollute the environment. This study therefore investigate the Physicochemical parameters of street dust and concentration of three toxic metals; Nickel (Ni), Copper (Cu) and Cadmium (Cd) in Arakale – NEPA Road in Akure City of Ondo State. A total numbe...
The effect of magnetic treatment of water on the growth, yield and germination of maize seed has a positive impact in Agricultural crop production
Abstract Indirect combustion noise had not been attracting research in the past, but recent indication seems to prove that it could be a threat in the future if not addressed. Means of reducing this type of noise to a low decibel value was also included. Noise is due to the ingestion of distorted atmospheric turbulence, as the two set of blades rotate in different direction. Open rotor noise is higher since the rotors are fully exposed to oncoming turbulence and lack ducting or a nacelle to a...
ABSTRACT This project presents the results of the investigation conducted on a lightweight foamed concrete using different reagents; Sodium Lauryl Sulphate (SLS) and Lithofoam, with a view to determining its potential as a construction material in Nigeria. The properties investigated on the foamed concrete having target density of 1800kg/m3 were: workability, bulk density and compressive strength. The foamed concretes produced using SLS were developed using a w/c ratio of 0.5 and a mix ratio ...
Wireless power transfer (WPT) technologies have been widely used in many areas, e.g., the charging of electric toothbrush, mobile phones, and electric vehicles. This project introduces fundamental principles of three WPT technologies, i.e., inductive coupling-based WPT, magnetic resonant coupling-based WPT, and electromagnetic radiation-based WPT, together with discussions of their strengths and weaknesses. Several WPT applications are described. Open research challenges are then presented wi...
ABSTRACT The adsorptive removal of the colour pigment (due to high content of carotenoids) from palm oil using ortho-phosphoric acid activated kaolin clay was investigated in this research. The clay was activated at different acid concentrations to improve its adsorptive capacity. In order to study the effect of process variables on the bleaching efficiency of the raw and activated clay ...
Focuses on the maximum volume of waste generated in a particular month in a particular area and uses a heuristic model for it's analysis. Research Problem A proper, efficient, reliable and hygienic waste handling and disposal technique tells more of our maintenance culture but the capacity and ability to efficiently manage the waste becomes inadequate. The need for this study a rose because effective waste management is a tool for sustainable development. This can be achieved...
Abstract In this report, we perform a comparison of two gas condensate stabilization techniques: fractional distillation and multi-flash vaporization. Our prime objective is to compare relevant parameters .e.g. Reid vapor pressure (RVP) and associated costs in order to determine the more effective method for the stabilization of our gas condensate feed. The Aspen Plus software application suite was extensively used for the process design and simulation as well as the economic analysis for thi...
ABSTRACT The maximum recoverable oil in place from the reservoir is a major challenge when it comes to EOR which is an essential part of every oil production project. In some cases, the natural drive mechanism is a relatively inefficient process and results in a low overall oil recovery. The lack of sufficient natural drive in such reservoirs has led to the practice of supplementing the natural reservoir energy by introducing some form of artificial drive, the most basic method being the inje...
ABSTRACT The presence of methylene blue (MB) in wastewater is a major concern in the environment due to its low biodegrability and harmful effect on man. The treatment of effluent containing such dye is important where adsorption on activated carbon (AC) produced from agricultural waste is of great choice. Optimization of the removal efficiency of MB from aqueous solution onto AC prepared from mango shell was investigated. The AC was prepared from mango shell, activated with BaCl2 at I.R (0.0...
ABSTRACT This study was conducted to remove mango shell waste which is one of the seasonal environmental nuisance items and recycle it as a precursor for the production of activated carbon. Discarded mango shells were sourced from local vicinity, and they were washed thoroughly to remove dirt, sundried and reduced to smaller sizes. Two-Level Factorial Design under Factorial Methodology of Design Expect (10.0.1) software was employed to optimize interaction of impregnation ratio (0.033 - 0.167...
ABSTRACT The document outlines an investigation done in order to study Fifth Generation (5G) systems and to identify a role that satellite systems will play in contribution to the many advanced and diverse demands on existing telecommunication networks. This next generation network is a build-up and phenomenal improvement in wireless communication done by the “5GPP” on the already existing mobile generations. The evolution has seen us move from first generation which employed analogue te...
