HOW TO PREVENT UNDERGROUND FIBER CABLE CUT

ABSTRACT Fiber optic communication systems have revolutionized the telecommunications industry, because it is used for faster transmitting of telephone signals, internet communication and cable television signal due to such lower attenuation and interference. The optical fibers are buried deep in the ground (1.2-1.5 meters) away from human activities. However, these fibers are been cut on frequently, the minute a fiber is cut, there is a halt in the smooth transition of signal.  To prevent...

Enhancing concrete properties with the use of coconut (coir) fibers and admixture

Abstract In countries where industrialization is on the rise there is a corresponding increase in waste production resulting from industries which eventually upsetsthe environment and community for which they provide. While most of these waste generated are hazardous and should be managed, others could be put to appropriate use either directly or after been recycled. Most agro-waste can be recycled and be used asraw materialsfor manufacturing various products. This research is designed to inv...

Health Effects of Air Pollution in Oleh Town, Delta State

The spread of pollutant in an area is partly a function of wood burning in local kitchens by the population of the area. This pollution generated through combustion of wood  fuels presents difficult environmental challenges to societies as it could degrade the environment and affect human health and quality of life. Wood burning emissions are major contributors to air pollution in rural areas as they contain harmful gases. The level of carbon monoxide in the air in two location in oleh town ...

Design and Construction of a Four Way Traffic Light Control

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...

PHYSICOCHEMICAL PARAMETERS & LEVEL OF SOME TOXIC METALS IN STREET DUST

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...

Effect of Electromagnetic Treatment of Water on Growth, Germination and Yield of Maize Crop

The effect of magnetic treatment of water on the growth, yield and germination of maize seed has a positive impact in Agricultural crop production

Design of Next Generation Civil and Military Aircraft with Ultra-High Bypass Engine using Composites, Advanced Materials and Technology

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...

Comparative Study On The Strength Of Lightweight Foamed Concrete Using Different Reagents (Lithofoam & Sodium Lauryl Sulphate)

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 ...

Contactless Power Transfer System Using Inductive Coupling-based Wireless power transfer (WPT) Principle

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...

KINETICS AND EQUILIBRIUM STUDIES OF COLOUR PIGMENTS REMOVAL FROM CRUDE PALM OIL USING ACID ACTIVATED KAOLIN CLAY

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 ...

Design of Effective Solid Waste Management System: A Case Study of Ifite-Awka zone, Anambra State

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...

Application of Reveal for polymer flooding modelling

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...

The Role of Satellite Network in future 5G wireless networks

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...

Commutation failures in HVDC Schemes

Commutation failures are very frequent dynamic events in high voltage dc (HVDC) transmission systems. Commutation failure is mostly observed at the inverter side of HVDC links, where large firing angles are used. The minimum value of the extinction angle required for the proper operation of a valve is specified by the valve manufacturer; however, at the inverter side of HVDC systems the extinction angle is regulated to a value higher than the valve specifications to allow control adjustments ...
