This seminar paper delves into the realm of ion thrusters, which have become pivotal in driving forward space exploration amidst the growing space industry and humanity's wish to traverse the vast expanse of the solar system. It traces the evolution of ion thrusters from its beginnings to becoming the backbone of propulsion systems for deep-space missions. The paper focuses extensively on the working principles of ion thrusters, particularly the electromagnetic principles that govern their op...
The main content of this project is to mathematically use the method of bilinear transformation to design a digital bandpass IIR filter, which will cut off frequencies below 20Hz and above 500Hz, since in electromyography the dominant frequencies for myopic signals lie between the frequency range of 20Hz and 500Hz.
This research work focuses on the comparative of FET and Bipolar power transistor performance in amplifiers. Field effect transistors (FET) have been widely used as transducers in electrochemical sensors for over 40 years. In this report, a FET transducer is compared with the recently proposed bipolar junction transistor (BJT) transducer. Measurements are performed on two chloride electrochemical sensors that are identical in all details except for the transducer device type. Comparative meas...
ABSTRACT This project is aimed at explaining the Design and construction of a digital wall clock with a calendar. It give report on how we can achieve this aim and the primary objective of this work is to bring a vibrant digital clock display to everyone located within the vicinity where the clock is being installed, and the importance of clock is to tell time and date, so you can meet up with events and assignments, these are just few importance of CLOCK. In developing co...
INTRODUCTION RADIO FUNDAMENTALS. Radio equipment are used for the transfer of information by electromagnetic means. A complete assembly of a radio circuit required to effect the desired transfer of Information is known as a telecommunication system. Common telecommunication systems include telegraphy, telephony, telemetry, television, radio etc. In general, the building block of wireless systems or otherwise include the transmitter, the channel and the receiver, The transmitter converts the...
INTRODUCTION TO NANOTECHNOLOGY Nanotechnology has gained ground in the twenty-first century and is rapidly growing due to the ability to manipulate and harness properties of assemblies that are at the nanosize scale of biomolecules. Bionanotechnology is defined by science’s growing ability to work at the molecular level, atom by atom, combining biological materials and the rules of physics, chemistry and genetics to create tiny synthetic structures [1]. The end result of nanotechnology...

ABSTRACT Nigeria’s dependence on conventional energy for power needs has been her undoing. Given the limited supply, and inherent dangers, her quest for electrical power self sufficiency has remained a dream. As the inhabitants of the world increases, pressure is placed on almost all the essential commodities for human satisfaction. The continuous supply of power from the national grid to industries and establishments has become a major problem thereby forcing some companies to go for gen...
ANTENNA SIMULATION: How to optimize your design. antenna are virtually everywhere from commercial applications such as smartphone,RFID tags and wireless printers, to deference application such as phased array antennas, to provide integral ground based communication systems. electromagnetic simulation is highly valuable tool in antenna design and platform integration. it provides the designer with the ability to virtually design and evaluate 'what if' scenarios as well as verify the fin...
AbstractThis project work focuses on the design and construction of heat detector for use in homes, industries, offices etc. It uses thermistor as the heat sensitive element; which is a type of resistor whose resistance changes significantly according to temperature change. The thermistor was connected as a voltage divider to one input therminal of the comparator (Pin 2) of the 555 timer IC as the resistance of the thermistor increases, the voltage at pin 2 decreases. Thus pin 1 becomes high ...
AbstractThe uninterrupted power is only dedicated for the purposed of illumination. Light is so important to man, so there is need to build an emergency lightening system to help reduce the problem encounter due o frequent interrupted power failure. This is reason for this project report which is CONSTRUCTION OF AUTOMATIC EMERGENCY LIGHTING SYSTEM. These project forms a stand-by source of light energy to man, it operates with the principles that when there is power failure the system will aut...
Abstract Digital (Fan) Regulator is one of the applications of electronics to increase the facilities of life. Fan is one of the unavoidable Electronic equipment in our day to day life. It has become essential element without which people can’t lead a smooth life. The presence of a fan in a house or office is not now considered as a luxury on the other hand it is included in the basic requirement. The uses of new electronic theories have been put down by expertise to increase the fa...
ABSTRACT Transient over voltages have often been blamed for the malfunctioning of electrical power systems. This seminar paper is an overview which seeks to describe the state of the power system under transient condition. It also provides information on the rate of occurrence, on the wave shape, and on the energy associated with the transients, as a function of the location within the power system. Also, the basic principles of coordinated protection with specific experimental examples are e...
ABSTRACT Congestion remains a major challenge to telecommunications service provision both to the service providers as well as the subscribers. This seminar work attempted to determine the causes of congestion and evaluated congestion control mechanisms adopted by service providers in Nigeria using MTN Nigeria as a case study. Findings from the study showed that apart from the carrying capacity of the MTN network other factors such as the use of phones for data transfer and multimedia activ...
