Design, Modelling and Fabrication of a Portable Solar Powered Suction Pump

Some inventions are glamorous and very sophisticated – microchips embedded system technology –and more while some others are quieter, yet not less relevant in easing the work that man has to do with his own energy. Pumps do fall in the latter category (Mario, 2001).This project is intended to model a portable solar powered suction pump. Pumps are devices that transfer fluids (liquid or gas) from one point to another through some mechanical means. Pumps generally have being in use fo...

Design and construction of an RF editable LED display board

This project is based on the design and construction of a Wireless Electronic Notice Board. It can be widely used to display latest information anywhere such as institutions, shop, place of worship and other places. This Wireless Electronic Notice Board will offer flexibility to user to control the information display within 50m to 200m range. Similar works were reviewed and the draw backs of these projects were cited and their advantage also considered.The desig...

Design

Solar powered systems have been built for various applications ranging from public lighting to water supply units but robust efforts have not been made in the development of pumping systems that can effectively replace the manually operated pumps used in field applications. Designing a machine that can pump the fluid without the need of so much energy on the part of the operator as well as boycott the use of direct electricity will hence be a reasonable contribution to field of maintena...

Development of a pedal operated breadfruit dehulling machine

ABSTRACTBreadfruit (Treculia Africana) or simply breadnut is very important  both as food and as a potential source of oil. The economic  importance of this tropical seed on domestic and commercial basis  has necessitated the development of a pedal breadfruit dehuller, that  would reduce the Cost of maintaining and purchasing motorized dehuller, Solve the problem of fuel scarcity, inadequate electricity supply . In the engineering design of this machine, the action zone co...

Scheffe’s Mathematical Model for Optimization of Compressive Strength of Periwinkle Shell Aggregate Concrete.

 This project work aims at formulating Scheffe’s mathematical model which prescribes concrete mix ratios for a desired compressive strength of periwinkle shell aggregate concrete and obtaining the  combination of water, cement,  river sand and periwinkle shell which will produce the optimum strength. The model was formulated from first principle producing an equation with several unknown coefficients. These coefficients were determined by carrying out compressive strength tes...

The role of informal Sector in employment generation in Ilorin, kwara state Nigeria

                       AbstractThis research work examined the role of informal Sector in employment generation in Ilorin, kwara state Nigeria. The study made use of primary data obtained from 100 respondents from Ilorin West Local Government in kwara state through the copies of questionnaire administered. The data collected was analysed using descriptive statistics and statistical package for social sciences (SPSS). The outcome of the empirical investigations showed that inf...

Catalytic conversion of polyethylene to liquid fuel and solid wax using the (CaOH2)

ABSTRACTThe objective of the work is the catalytic conversion of waste plastics into fuel oil and solid wax using Ca(OH)2 and the design of pyrolysis reactor. Plastic wastes such as, polypropylene, low density polyethylene, high density polyethylene, polystyrene are the most frequently used in everyday activities and disposed of to the environment after service. There are a number of methods by which plastic wastes can be managed such as incineration, recycling, land filling, thermal and cata...

Pultruded FRP-Concrete hybrid beams: characterization of shear connection behavior through static push-out tests

This paper discusses the recent investigation into the composite action of pultruded Fibre Reinforced Polymer (FRP) and concrete hybrid systems, under static push-out tests. The study sought to experimentally determine the characteristic load-slip behaviour of the FRP-concrete composites under varying shear stud arrangements and failures modes associated with the variations and the push-out load capacity. For the initial tests, three composite test spe...

Some Ecological Disasters And How They Affect The Human Environment In Nigeria

Ecological DisastersA “disaster” can be defined as ‘a calamitous event, especially one occurring suddenly and causing great loss of life, damage or hardship, caused by negligence, bad judgment, or the like, or by natural forces, as a hurricane or flood….the emphasis is on grief or sorrow caused…or the destruction or irreparable loss. they often come with such inexplicable emotional force that triggers in man that innate human desperation or determination for survival against a...

Inhibition of corrosion on AISI 4137 steel in H2SO4 using Cascabela thevetia and Jatropha curcas leaves

Abstract: Inhibition of corrosion on AISI 4137 steel in H2SO4 using Cascabela thevetia and Jatropha curcas leaves as inhibitor was studied using gravimetric and gasometric analysis. It was found that the leaves extract of both plants act as a good corrosion inhibitor for AISI 4137 steel in all concentrations of the extract ranging from 0.3 - 1.5 g/l and the inhibitive efficiency increases with increasing concentration of inhibitor. Cascabela thevetia has better surface coverage than Jathr...

Car security control using RfId

ABSTRACT Security Car Using RFID System. This project is designed to enhance vehicle safety systems available. Thus, this project consists of some combination of equipment and components to create a car security system that meets the security features and use more advanced. RFID (Radio Frequency Identification) is the most reliable way to electronically identify, data capture, control, track, and inventory items using RF communication. Thus the project was produced by using RFID (Radio F...

Development of speech accent adaptation algorithm

ABSTRACTThe serious setback in modern day Automatic Speech Recognition (ASR) technology is posed by intonation differences which results in acoustic and durational variability; a problem that hindered the full exploration of this area of research and the development of the speech technology product globally. This work developed an algorithm that is capable of adapting to the accent of the focused Nigerian major tribes (Hausa, Yoruba, Ibo, and Fulani) thereby improving the development of local...
