ABSTRACT In the last decade, there was rapid growing of Wireless Sensor Networks (WSNs) for research and commercial uses. Low-cost/low-power WSNs techniques are utilised in various applications such as smart-home, industrial control, health care, agricultural fields, environmental purposes, biomedical systems, and scientific applications. The aim of this research is to find the suitable number of paths and hops in each path to be used in transmit power control protocols for multi-path unifor...
ABSTRACT The Automated Guided VehicleAGV or a programmable mobile vehicle is capable of transportation task fully automated at limited area such as using in industrial applications to transfer material and production around a manufacturing unit. In the traditional industry materials and products are transported and moved using workers which lead to waste of the time and increase labour cost. Also its unsafe for the workers themselves by exposing them to bone and muscle diseases and exposing ...
Abstract Wireless charging through inductive coupling could be one of the next technologies that carry the futures forward. In this study it has been shown that it is possible to charge low power devices wirelessly via inductive coupling. It minimizes the complexity that arises for the use of conventional wire system. In addition, the thesis also opens up new possibilities of wireless systems in other daily life uses. Much interest in the research has been conducted to determine the feasibili...
ABSTRACT The topic of today's lecture concerns Electricity as it exists in Nigeria from the very beginning. The lecture will take us through the developmental stages of Electricity infrastructure in Nigeria from the beginning to what it is now. We all know that the engine of life the world over, is the uninterrupted electrical power supply. We also know that there is a very strong link between the per capita consumption of electrical power and the state of physical advancement of a nat...
Abstract This research study process of combined process of injection of preform and immediately then blowing of these preform on the same machine. Such a process has its advantages compared with the traditional sequence of preform injection in one machine and later the blowing of the preform to produce the bottle. Process combined products like pharmaceutical bottles made in a small size are not susceptible to pollution and more economical, in the case of the separate process becomes more ...
Abstract Rural health service is an important national and international priority. However, the availability of electricity to support proper rural health services is less than adequate in many countries. In recent years the development of reasonably priced and reliable energy systems has made it possible to provide vaccines and other basic health care services in remote areas. A number of international, national, local institutions and private companies are now deploying renewable energy sys...
ABSTRACT This thesis dealt with suitable fabrics to protect human skin from ultraviolet rays (UV) using nanomaterial. Nanomaterials have attracted much of attentions that due to their unique properties demanded in various applications. Their used in textile finishing for imparting advanced functions for textile fabrics attracted many scientists. In this study, novel nanodiamond composites were developed for textile fabrics coating .The nanodiamond were well dispersed in coating by using ultr...
ABSTRACT This study is concerned with the production of high strength concrete using recycled concrete aggregates as alternative to natural aggregates. The study includes also the determination of the proportions, characteristics and components of concrete mixes required for production and use in multiple applications at suitable prices. The basic materials used in this research (ordinary Portland cement, natural aggregates, recycled concrete aggregates, natural valley sand, local tap water ...
ABSTRACT A sample of high density polyethylene and graphite powder was made to study the effect of graphite power content on the electrical properties of high density polyethylene, graphite offers the benefit of low density and cost when compared to metallic substances used for the same function , the sample was tested with different concentrations of graphite powder (30,40,50)% and in different temperatures, the study reached to the following results: The conductivity of the HDPE was increa...
ABSTRACT Every semester, students from each school in AUN take on their Senior Project. This project is expected to be a culmination of their work at the University and represent what they have learned. One of the biggest issues students have is what project they should take on. From the inception of AUN, there have undoubtedly been a great number of projects that have been done. Some could have been expanded upon or even improved; there has however seldom been an opportunity for this to tak...
ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of change of current with time have been identified as the input variables, duly represented in the programme as “Error” and “Error-Dot”. Thes...
ABSTRACT The construction industry in developing countries is under tremendous pressure to improve its performance and the quality of its products and services. The small-scale construction firms dominate the construction industry and governments had globally recognized micro and small-scale enterprises as an instrument of economic growth and development. Past studies by various researchers have recommended a number of performance improvement strategies. However each country has peculiar prob...
ABSTRACT The study was undertaken to measure the variational change in residual chlorine decay in water distribution network. A total of 330 water sample were collected at different periods of the day for ten days. Ten water sample locations at water stand taps, were taken for the study area in Calabar South Local Government Area of Cross River State, Nigeria. The effect of various Pipe diameter, water sample point distance, change in chlorine concentration with time on residual chlorine and...
Abstract In industries like oil and gas, Telecommunication Networks used multiple communication technologies to eliminate any possibilities of failures, when the network is operational, in case of catastrophic situation these networks have strict and tight requirements for robust. Accordingly availability of the transmission network is essential, even short interruptions especially during catastrophic risks may cause considerable economic losses and major environmental impacts. In reality th...
Abstract Sediments resulting from soil erosion are the major non-point source pollutant of surface waters in agricultural watersheds. Annualized Agricultural Non-Point Source Pollution Model (AnnAGNPS) is a computer-based watershed model that predicts non-point source pollutants and runoff loadings within agricultural watersheds. AnnAGNPS v5.2 was used in conjunction with Arcview 3.2 GIS to predict streamflow and sediment discharges from a 250.89 ha agricultural watershed, Upper Ebonyi River...
