The Design and Construction of A Mobile Station Compatible Hearing Aid (with Volume and Pitch Control)

ABSTRACT It would seem that hearing is a secondrate sense when compared to vision in our visually oriented modern society. People with hearing loss delay a decision to get hearing help because they are unaware of the fact that receiving early treatment for hearing loss has the potential to literally transform their lives. Research by the National Council on the Aging on more than 2,000 people with hearing loss demonstrated t...

A Web- Based Management Information System for National Health Insurance Scheme

ABSTRACT A web-based information management system for national health insurance scheme(NHIS) will assist the body to have an online registration of people, health maintence organizations (HMOs), accredited heath care providers, etc. Looking at the Nigerian population, access to health insurance is denied to a certain category of people as a result of not being a government worker or not privileged to be duly informed on the operation of the scheme and how to enroll Knowing that Health insura...

Development of Jos Tv Broadcasting Studio Reliability Model

ABSTRACT The broadcasting stations in Nigeria often encounter sudden failures, which results in loss of signal that causes the station to experience down-time. Causes of the failures could be traced to the issues that range from erratic power supply to degradation in the studio equipment. Each failure and its consequent down-time influences the reliability of the station. In our environment (Nigeria) reliability does not only depend on the established parameters, instead it includes parameter...

Strategies For Optimizing Password Management Against Versatile Attacks

ABSTRACT Managing passwords is a significant problem for most people in the modern world. Passwords are a critical part of information and network security. Passwords serve as primary authentication method to protect user accounts but a poorly chosen password, if compromised, could put the entire network at risk. Many users do not understand why good passwords and password management are important for information systems. “We’re secure! We use passwords!” How many of us have heard...

Design And Construction Of A Door Lock Alert System Using A Microcontroller

ABSTRACT This project focused on how one can safely keep the house safely locked through minimizing the access to its door unit, monitoring whoever is trying to open the door and providing an alert to the security agencies in case he/she is proved an intruder by the system. The work is arranged mainly in five chapters, Chapter one includes the introduction of a system. Chapter two discusses the literature related to the system, Chapter three illustrates the methodologies used in coming up wit...

Design And Fabrication Of An Electronic System For Pressure And Temperature Measurement In Thin Film Deposition Systems

Temperature and pressure are quantities of great importance in various applications such as integrated circuit (IC) manufacture and vacuum coating just to mention a few. Therefore, their accurate measurement is inevitable. However, it is tiresome to measure and record these quantities manually by pen and paper when operating a thin film deposition system. This approach is not only time consuming but also causes human errors on the measured physical parameters. To solve this problem, an automa...

Compressionion Of Pulse Code Modulation Signal Using Type Iv Discrete Cosine Transform Based On The Mp3 Model.

Digital signal compression in the recent past has become the mainstay of the basic technologies of multimedia due to the bandwidth and storage limitations inherent in networks and computers. The change from circuit switched to packet switched systems in the telecommunication infrastructure in the past few years, has reflected on the way Pulse Code Modulation (PCM) signal which in essence is a raw audio signal, is carried in present systems. The purpose of this study was to design an applicati...

Designing And Fabrication Of A Current-Voltage Curve Meter For Electrical Characterization Of Photovoltaic Modules

In the recent past the use of renewable energy as an alternative source of energy has increased considerably. The solar cells modules manufacturing technology is becoming more reliable and economical. The feasibility of photovoltaic solar energy as an alternative source of energy has   become real. The low efficiency and the weather condition dependency give room for improvement of this technology to extract maximum power for different environmental conditions. Therefore, the current–volt...

Study Of Snxsey Thin Films For Phase Change Memory (Pcm) Applications

Phase Change Random Access Memory (PCM) is one of the most optimized candidates for the next generation non-volatile memory due to its fast operation speed, high scalability, low power operation and fabrication costs. The transition from the amorphous to the crystalline phase is induced by heating the material above its crystallization temperature for a long enough time, and the switching back to the amorphous phase is realized by melting and quenching the material fast enough that it solidif...

Optical And Electrical Characterization Of Cdxse1-Xs And Cu2sthin Films For Solar Cell Application

ABSTRACT There has been a steady increase in demand for clean and renewable energy globally. As a result, more effort has been put into research to harness solar energy from the sun to generate electricity using solar cells. Solar cells convert solar energy directly into electricity. Recent research findings indicate that properties of thin film solar cells strongly depend on the various deposition techniques chemical bath deposition (CBD) being one of them. This technique yields stable, adh...

Design Of An Intelligent Room Light Controller With Bidirectional Counters For Energy Efficiency Applications

ABSTRACT Despite the installation of light energy waste control systems in modern buildings, many people end up paying for high energy bills. The cost of installation of these systems is usually high, and most of them are inefficient making it a major concern to the normal user. Due to technological advancement, sensors and microcontrollers are employed in a wide range of applications. This includes domestic and industrial fields where they aid in control of automated processes. In these app...

Design And Fabrication Of Aperture Coupled Microstrip Patch Antennas With Arbitrarily Shaped Apertures

ABSTRACT A linearly-polarized aperture coupled microstrip antenna design is characterized and optimized using FEKO antenna simulation software. One of the major drawbacks of these microstrip antennas is their narrow bandwidth. Aperture coupled being one of the feeding technique has proven to be a solution to this problem. In this research a patch antenna that is coupled to a microstrip-line by an aperture in the intervening ground plane has been designed and fabricated and implemented. The sh...

Characterization Of Cdxse1-Xs/Pbs Thin Films Deposited By Chemical Bath Deposition For P-N Junction Solar Cell Application

ABSTRACT The CdS and PbS are of great research interest due to their outstanding electronics and optical properties such as winder energy band gap phase and good antireflective properties respectively. CdS has been earlier doped by Zn and used as a window layer combined with PbS as the absorber material using the CBD method. It realised an efficiency of 0.9. It is for this reason in my research, I doped CdS with Se in the fabrication of CdxSe1-xS/PbS PN junction for solar cell application to...

Optical And Electrical Analysis Of Cd1-Xfexs/Cus P-N Junction For Solar Cell Application

ABSTRACT The rapid population growth in Kenya and the world in general has led to very high energy demands; this has necessitated urgent exploration of other alternative energy sources. Solar energy is one such alternative that has not been fully utilised hence many researchers have developed much interest in them. Solar cells absorb light from the sun and convert it in to useful electrical energy however the challenge has been how to harness it as well as the very low efficiencies recorded b...

System Sizing Of Solar Energy Requirement For An “All-Direct Current” Stand-Alone Telecommunication System

ABSTRACT Solar photovoltaic (PV) energy has been widely used for decades especially where connection to a national grid is seldom possible and other sources such as fossil fuel and others are either unavailable or uneconomical. Solar PV energy owing to its free, natural availability and environmental friendliness has found demand for use in industries, homes and institutions. However, very little research has been carried out to precisely establish its effectiveness, reliability and adequacy....
