ABSTRACT FM bugger is a device which generates frequency modulated signal. It is one element of a radio system which, with the aid of an antenna, propagates an electromagnetic signal. Standard FM broadcasts are based in the 88 - 108 MHz range. The signal (from the microphone) is fed into the audio frequency (AF) for amplification then to the modulator which combines the modulating signal with the carrier wave transports the modulated signal through (RF) for final amplification to t...
ABSTRACT This project report is an excerpt of the design of a Micro-controller based Access Control Lock system implemented to assist the university with the aid of security personnel in the prompt detection of students who have not completed necessary fees payment and to checkmate the problem of the ever increasing rate of examination impersonation perpetuated by students. The Micro-controller based Access Control Lock system is an automatic software-based system having two major part...
ABSTRACT In this project work, a hybrid cloud system using StackOps Distro Community Edition was designed and implemented. The Electrical and Electronic Engineering Department of the Federal University of Technology, Owerri was used as a case study. This is essential as there is greater need for readily available and on-the-go Information and Communication Technology services. Ubiquitous access to data, files, documents, project work and the like are vital in all spheres of life, and e...
ABSTRACT According to the definition of Third Generation Partnership Program (3GPP), Machine Type Communication (MTC) is a new type of data communication between machines and devices without human interactions. Long Term Evolution (LTE) is a recent 3GPP cellular standard and is a promising technology to support future MTC data traffic. One of the main goals of LTE is to provide fast and seamless handover from one cell to another to meet strict performance requirements while simultaneous...
ABSTRACT A means of providing radio broadcasting services by using Frequency Modulation (FM) technique is called FM Broadcasting. Aeronautical Communication Service refers to radio communication service intended for the safety operations of aircrafts. Aeronautical communication service is categorized by International Telecommunication Union (ITU) as a primary service. This service needs to be offered under frequency interference free environment for ensuring aircrafts navigation safety...
The exponential growth of mobile data traffic affects not only the capacity requirements of the mobile networks, but even the expected quality of service. The introduction of LTE improved the situation to some extent. However, as a high percent of mobile data traffic is generating from indoors, LTE operating at higher frequencies cannot really meet the ever-increasing demand of data traffic and reasonable quality of service. This Thesis provides an analysis of the network throughput wit...
ABSTRACT Models for radar detection targets under complex electromagnetic environment were established, including clutters and active electrical jamming. MTI filter based clutter rejection technique is presented. RADARs with fixed carrier frequency profile are vulnerable to jamming; Frequency agility is one of the best techniques used for anti jamming by changing the carrier frequency of the radar.
ABSTRACT Recently, in most of the developing countries like Tanzania, life expectancy and the inherent costs of caring for an aging population are increasing. These have put an enormous demand on the health care systems and have driven the advancement of technology-based sensor devices that can remotely monitor key vital life signs. These advancements enabled proliferation of wireless sensor networks. These sensor networks are capable of monitoring and controlling environments remotely,...
ABSTRACT Over the last few years, there has been mounting concern about the possibility of adverse health effects resulting from exposure to radio-frequency electromagnetic fields. Such emissions from wireless communication devices like mobile phones. Since then, researchers, scientists, and other professionals have issued many reports that prove either a correlation between radiations emitted by mobile phones and health related hazards (cancer, reproduction, car accidents etc) exis...
ABSTRACT Wireless indoor positioning systems have become very popular in recent years. These systems have been successfully used in many applications such as asset tracking and inventory management. Although satellite-based Global Positioning Systems (GPS) and Cellular Networks (CNs) have empowered a variety of location based services but they do not work well in indoor environments where walls and excessive multipath objects greatly attenuate satellite and cellular signals. In most ca...
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 t...
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 the...
ABSTRACT Automated Fish Feeder is a system, which focuses on aiding small scale fish farmers to feed their farms efficiently. By using Arduino and Internet of Things, this is made possible. This provides fish farmers with time and adequate information as the system is set to feed at several time intervals and send information through the internet should the feed container be low or empty . In addition, the system has so many potentials. The system can be embed into other systems such a...
ABSTRACT In Power line communication the information are sent via electrical power lines. The power lines are characterized by multipath fading and frequency selectivity due to impedance mismatch of the channel and impulsive noise. Therefore there should be a way to increase performance of the system. In this dissertation OFDM and MCSS modulation techniques were used to enhance PLC system performance. Bit Error Rate (BER) performance of OFDM and MCSS was analyzed and system efficie...
AbstractThe main objective of this project was to design a cost effective and efficient electronic voting system interfaced with a GSM module. There is need to replace the conventional voting system based on paper in Zimbabwe and many African countries by electronic voting machines which are cheaper, more secure and less cumbersome. Voting is when societies or a particular group of people come up with decisions based on choice and or preferences hence the need for a cheaper, more secure,...
