Development And Evaluation Of An Integral Passive Solar Crop Dryer

ABSTRACT A direct-heated solar crop dryer suitable for rural farmers and households was developed and evaluated. The simple structured dryer was fabricated using square and round pipes, aluminium sheet, Perspex, wire gauze, bolts and nuts. Its performance was evaluated using cassava chips and three cylindrical aluminium chimneys of heights 1200mm, 800mm and 400mm; all of equal diameter. Mature cassava roots were peeled, washed, chopped into flat circular chips of 10mm thickness and spr...

Developing Rainfall Models For Enugu City

ABSTRACT Suitable rainfall models of Enugu City is presented based on the statistical method of least squares. A total of 23 rainfall models are developed in all and grouped into 2 sets. The first set contains 4 rainfall models which represents an inverse relationship between rainfall intensities and durations for specified return periods of 1.1, 2.2, 5.5 and 11 years. High and positive values of coefficients of correlations of 0.9735 to 0.9885 were obtained; an indication of good curv...

Determination Of The Hydraulic Conductivity And Infiltration Capacity Of The Fedral Unversity Of Technology Owerri (Futo) Farm

ABSTRACT This thesis describes the in situ methods of the determination of both the hydraulic conductivity and infiltration capacity of the Federal University of Technology, Owerri (FUTO) farm soil. The inverse anger hole method was chosen to determine the hydraulic conductivity due to its simplicity and effectiveness. Cognizance was taken of the factors as presented in the project report that affect the results determined. Also the various methods of determining the two parameters were...

Determination Of The Compressive Strength Of Palm Kernel Shell Concrete

ABSTRACT This study is on the determination of the Compressive Strength of Palm Kernel Shell Concrete. The effect of percentage replacements (0, 25, 50, 75 and 100%) of crushed granite with palm kernel shell on density and compressive strength of concrete is presented. Concrete cube specimens of mix 1:2:4 were prepared with water-cement ratio of 0.6. The cubes (150mm×150mm×150mm) were cured using water-submerged curing until testing ages of 7, 14, 21 and 28 days when their densities a...

Design Of Community Informatics Social Network Web Application: A Case Study Of Niger Delta Region Of Nigeria

ABSTRACT In this research, Social Network Web Application (SNWA) was developed and tailored for a specific use; community development in the Niger Delta region of Nigeria. In the SNWA development, preliminary context analysis was conducted to capture contextual information on community development challenges in the Niger Delta and the readiness of the target local community to adopt web-based solution to the identified challenges. Subsequently, User-Centered Requirement Engineering, Us...

Design Of A Robust Electronic Internal Temperature Controller For Petroleum Distillation Columns

Abstract Design of a Robust Electronic Internal Temperature Controller for Petroleum Distillation is presented in this Thesis. During unstable weather conditions, there is a noticeable drop in the distillation internal column temperature. An extreme and frustrating case of this occurs during rainfall and at night when the fractional distillation column external temperature drops, greatly affecting the internal. Consequently, it becomes difficult to maintain a stable and optimum interna...

Design And Performance Evaluation Of A Parabolic Solar Cooker

Abstract The design, construction and performance test of a parabolic solar cooker for domestic use are presented. The simple experimental parabolic solar cooker, made of locally available materials, consists of a parabolic dish of thickness 0.3mm, adjustable mechanism, pot, pot holder, base support and a reflecting glass surface. The concave surface of the dish was lagged with reflective glasses which serve as a reflecting surface. Commercially available (3mm) thick glass is used as gl...

Design And Implementation Of A Hybrid Cloud Using Stackops Distro Community Edition

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...

Design And Development Of Computer Based Test System To Facilitate E-Exam.

ABSTRACT The purpose of this project was to design and develop a Computer Based Testing (CBT) system in order to facilitate the process of conducting e-examinations especially in tertiary institutions. There is a growing need to find an easy and effective way to carryout continuous assessments for the increasing population of students. The CBT system will afford instructors the opportunity to assign different weights to the multiple choice questions. The method adopted was a client/serv...

Design And Development Of An Evaporative Cooling System For Fresh Fruit And Vegetable Storage

ABSTRACT An evaporative cooling system was developed with locally available materials. The system was aimed at providing lower temperature and higher relative humidity necessary for extending the shelf life of fruits and vegetables. The performance of the cooler was evaluated in terms of temperature drop, humidity gain, cooling efficiency and quality assessment of the stored products. Two categories of test were carried out on the cooler with the chosen absorbent materials: the no-loa...

Design And Development Of A Hybrid Solar/Charcoal Fish Smoke-Dryer

ABSTRACT An indirect, natural convection solar-assisted charcoal smoking system was designed and fabricated in one of the host communities of the Federal University of Technology, Owerri where most of the fish farmers and processors adopt the conventional method of drying fishes, that is, using firewood. This method which works well during the dry period of the year is very inconvenient during the rainy season. Given the excessive heat generated by firewood and its resultant effect on t...

Design And Construction Of A Wireless Smart Meter

Abstract Consumers’ complaints of estimated bills from the Utility have risen to an alarming extent in recent years. On the other hand, Utility incurs huge losses attributing it to electric energy consumption theft among consumers. These complaints by the utility and the consumer led to the quest for a system that in addition to recording energy consumption data, will be able to compute and report the data to the Utility remotely. This work proposes the implementation of smart meter ...

Design And Construction Of A Robotic Arm With Adaptive Behaviour

ABSTRACT This project work covers the design and construction of a robotic arm mechanically capable of 5 Degrees of Freedom. It solves the problem of automatically detecting and picking up objects placed within distances of 10-30cm round the robot base platform. It does this by using a simplified forward and inverse kinematic relation modeled in two dimensional robot workspace. The work does not cover the more general case, of an n-linked (n>2) robotic arm working within a three dimens...

Design And Construction Of A 40a Intelligent Charge Controller For The Department Of Electrical And Electronic Engineering

ABSTRACT This project presents a 40A maximum power point tracking solar charge controller. The MPPT charge controller tries to keep the voltage and the power stable. The MPPT charge controller will harvest more power from the solar array – it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. An MPPT charge controller is an electronic DC to DC converter that ...
