Design and Construction of Permanent Magnet Generator

ABSTRACT  A drastic change in the perception of electric energy . But at the same time there is misreading of FREE ENERGY. Energy becomes free only at a point after which we don’t have to pay for power generation after hiring the unit. By using the magnetic force of magnets continuous motion (Energy) is made. This magnet also produces a magnetic field, so both the magnetic fields repel each other (like poles repel), which reasons the fins to move. The free Energy Generator was mounted in...

COMPARISON OF THREE STATISTICAL METHODS FOR ESTIMATING WEIBULL PARAMETERS FOR WIND ENERGY ANALYSIS

There is a crucial need in the mainland regions of Nigeria to enhance the development of wind technology and engineering, which is essential for the designing of Wind Energy Conversion Systems (WECS). The Weibull Probability Density Function (PDF) with two parameters is widely accepted and commonly utilized for modelling, characterizing and predicting wind resource and wind power, as well as assessing optimum performance of WECS. Therefore, it is paramount to precisely estimate the scale and ...

Systematic study of z transform and its analysis on Discrete Time Systems

                    ABSTRACT In this project work, we have established a systematic study of z transform and its analysis on Discrete Time (DT) systems. The researcher also deal with Linear Time Invariant (LTI) system and Difference Equation as examples of DT systems. The right and left shift was use as a method of solution of the z transform to linear difference equation. CHAPTER 1                                                   �...

COMPUTERIZED LEARNING AND TEACHING MANAGEMENT SYSTEM

In this project i have explored the use of Information Communication and Technology to help students have access to learning resources such as course content online, downloadable materials. With the learning management system we designed and implement. Students can download materials to be read online or offline. It involves redefining the importance of e-learning, design issues and strategies to promote interactivity and active learning, learning support, policy and management issues. E-lear...

AN ONLINE BOOK-BANK MONITORING SYSTEM

This project was aimed at developing an online book-bank monitoring system in Makerere University. The responsibility of monitoring book-banks in Makerere University is vested in the main library and is executed by the Bank-Bank section. It was intended to address the current problems encountered in using a manual system to monitor the activities of the book-banks. The study covered three book-banks namely; Faculty of Computing and IT, Faculty of Law and Department of Adult Education and Comm...

Fullwork-A System for Health Document Classification Using Machine Learning

Due to the massive increase in medical documents every day (including books, journals, blogs, articles, doctors' instructions and prescriptions, emails from patients, etc.), it is becoming very challenging to handle and to categorize them manually. One of the most challenging projects in information systems is extracting information from unstructured texts, including medical document classification. The discovery of knowledge from medical datasets is important in order to make effective medic...

The relationships between students’ attitude towards mathematics and their performance in mathematics

It is said that mathematics is the gate and key of the sciences. According to the famous philosopher Kant, “A science is exact only in so far as it employs mathematics”. So all scientific education which does not commence with mathematics is said to be defective at its foundation, In fact it has formed the basis for the evolution of scientific development all over. Taking into cognizance, the usefulness, relevance and importance of mathematics, like bringing positive changes to the scient...

Assessment of some micronutrient in sesamum indicum

ABSTRACT Sesamun indicum is used for both domestic and commercial purpose in Northern Nigeria, this research is aimed at assessing some micronutrients in sesamum indicum seed in Nguru town, using atomic absorption spectroscopy, spectrophotometric and flame photometric techniques in order to determine the elemental concentrations of  some elements in sesame seeds collected from Nguru town, Nguru local government of Yobe state, Nigeria. The results showed the presence of sodium (Na), potassium...

ALFRED NON-OIL EXPORTS ON ECONOMIC GROWTH

ABSTRACT The research focuses on the impact of non-oil exports on Nigerian economy. It employs the documentary method in retrieving secondary data for the study. The data is retrieved from the CBN statistical bulletin for the year 2016. The method of data analysis is the ordinary least square (OLS) method of multiple regressions using the Microfit software. At the end of the analysis, it is discovered that non-oil exports has a significant impact on the economic growth of Nigeria. I recommen...

CORRELATIONS BETWEEN ELECTRICAL PERFORMANCES OF POTATO BATTERIES TREATED UNDER THREE DIFFERENT CONDITIONS.

ABSTRACT Using basic galvanic cell principles, the ability of tissues to generate electrical current through electrolysis was characterized. Studying Zn/Cu electrolysis in animal organs revealed a fundamental and measurable tissue-specific property – the galvanic apparent internal impedance (GAII), that is most likely related to the salt bridge function of tissues delineated by electrodes. We now report on new fundamental studies on GAII in vegetative matter and on a simple way for signific...

Protein

Protein is an essential nutritional supplement of food that contain may elements of Amino acid  CHAPTER ONE1.1 INTRODUCTION Milk is one of the most nutritious foods. It is rich in high quality protein providing all tenessential amino acids. It contributes to total daily energy intake, as well as essential fatty acids,immunoglobulins, and  other   micronutrients.   Cow’s   milk  is the   predominant   type   in  severalcountries,   although   goat,   buffalo,   sheep...

THE USE OF GEOSPATIAL APPROACH IN ASSESSING LANDUSE AND LAND COVER OF MADALLA IN SULEJA LOCAL GOVERNMENT AREA, NIGER STATE

                                                   ABSTRACT This study examines the spatial and temporal changes in land use and land cover of Madalla in Suleja Local Government Area (LGA) of Niger State between 1984 and 2013, as well as, the rate of change, factors responsible and suggests measures on how to check the trend in order to maintain sustainable development. The study utilized ILWIS 3.3 software for the processing and classification of the tri-date (19...

DESIGN AND IMPLEMENTATION OF AN ENHANCED CHILD DIAGNOSTIC EXPERT SYSTEM

Detecting diseases in a child at early stage can enable one to overcome some avoidable diseases that can lead to death of the child and treat them appropriately. This system is poised at a greater extent to reduce infant mortality rate. The Enhanced Child Diagnostic Expert System (DExS) can help the nursing mothers, parents, nannies, guidance and crèche teachers even the medical personnel a great deal in identifying specific diseases and describing methods of treatment to be administered. Th...

Determination of levels of lead in paints to which young children and adults are exposed.

The Paint samples were gotten from old houses in areas of Ikorodu, Onipan, Lekki, Berger, Agbado-Ijaye, Lagos Island, Moremi and Makama hall (University of Lagos) and were digested using three different methods, which include 1) Nitric acid and per-chloric acid digestion 2) Nitric acid and hydrogen peroxide digestion 3) Dry ashing digestion using muffle furnace     These methods were compared and was discovered that oil - based paints (gloss paints) has higher concentration of lead tha...
