Reliability Analysis of Continuous Beam Using Hasofer-Lind Reliability Method

This project work “Reliability analysis of a continuous beam using Hasofer-Lind Reliability Method” was primarily concerned with the effect of varying parameters such as load, modulus of elasticity, moment of inertia and span length on the reliability of a continuous beam. The limit state considered is deflection, and the allowable deflection is specified as L/360. The maximum deflection is 0.0069wL^4/EI and it occurs at 0.446L from either end (AISC, 1986). Reliability analysis, expre...

Basic Principle of Machining and Arc Welding

ABSTRACT This project tittle ‘’basic principle of machining’’ deal with the operations on lathe, milling and some part of arc welding, turning, taper turning, threading, knurling and chamfering, while on milling machine spur Gears were cut, forming a hexagon shape and square shape were all done on milling machine. A simple component/part which contained all the above mention operation were produced in one work piece. In conclusion we are able to produce spurs gears, square thread, an...

Design and Construction of a 4 Way Inter-Communication System

ABSTRACT An intercom is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones. Four-way intercommunication system is nothing but the communication within four persons not close to one another. This does not mean w...

Design and Development of a Hybrid Bicycle

This project involved the conversion of a conventional bicycle into an electric hybrid bicycle using a hub motor, battery, controller, throttle, and battery indicator. The selection of a flywheel-based regenerative mechanism was justified based on its superior energy storage capabilities. The challenges faced during the assembly, including bearing and clutch drive iterations, were overcome through the use of multiple bearings, metal casting, and welding. The implementation of an indirect...

Prototype of Autonomous Vehicles Using Image Processing & Raspberry Pi

ABSTRACT An innovative approach to achieving autonomous vehicle navigation through the integration of image processing techniques and the Raspberry Pi platform. The aim is to develop a self-driving system that can analyze real-time images captured by onboard cameras and make informed decisions based on the detected objects and road conditions. By employing advanced computer vision algorithms, such as object detection and lane detection, the system can identify and tracking obstacles, recogniz...

Design and Construction of a Vehicle Tracking and Accident Alert System Using GPS and GSM Module

This project is about the Design and Construction of a Vehicle Tracking and  Accident Alert System (VTAA) using GPS and GSM Technology. It comprises of  integration between GPS receiver, microcontroller and GSM module, and of  course the push button for accident alert activation. The combination of all this  technology will produce our VTAA system. The GPS module receive the  coordinate of the point at which the system is located, controlled by the user using  command interfaces through...

Implementation of Web-Based Health Management System for National Health Insurance Scheme

ABSTRACT Web-based health management system for National Health Insurance Scheme is considered in this project work as an online information storage and retrieval internet portal where the stakeholders registered and participating in the National Health Insurance Scheme of the federal ministry of Health will be able to access relevant information regarding NHIS. The Internet portal will also be useful to prospective or intending participants who want to key into the programme. The stakeholder...

A Fault Detection and Protection Scheme for a 200 MVA Transformer using Fuzzy Logic

ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of change of current with time have been identified as the input variables, duly represented in the programme as “Error” and “Error-Dot”. Thes...

Design Analysis of HCCI Engine Piston

The piston is a heart of the engine and its working condition is the most exceedingly bad one of the key parts of the engine in the workplace. A piston is a segment of responding piston, responding pumps, gas compressors and pneumatic chambers, among other comparative systems. It is the moving part that is contained by a barrel and is made gas-tight by piston rings. In a piston, its motivation is to exchange force from growing gas in the barrel to the crankshaft through a piston bar and addit...

NanoCharge DNA Sensor - Folded Floating Gate CMOS Biosensor

A CMOS biosensor with a folded floating-gate is created to detect charged biochemical molecules. It contains a FET, a control-gate and a sensing area. The floating-gate spans the whole device, allowing the sensing area to be placed on top of the FET, resulting in a decrease of the device's total area. The device is sensitive to the polarity and quantity of charged poly amino acids and could be used for electronic recognition of temporal and spatial migration of charges, such as in biological ...

Dispersion Studies in River Ebere

ABSTRACT The Conventional Levenspiel and Smith fixed point continuous monitoring method is used in the evaluation of the dispersion number and the dispersion coefficient, I? of river Ebm under study. Comparisons were made with Agunwamba’s method and both methods for different results. The leverspiel and Smith method gave higher values than those obtained with the Agunwamba's method except in me station. This is due to experimental errors. The Agunwamba's method though more tedious gave mor...

Design and Development of a Data Ware-House for School Information System Case Study of Heritage International School

ABSTRACT  Data warehousing and business intelligence are key enablers in the drive to harness management information and improve decision-making. They underpin the recent wave of interest in data mining and customer relationship management, and create opportunities for performance improvements based on quantitative analysis at every le-vel in an organization. Data warehousing is a relatively new field in information technology, and current research centers primarily on data warehousing in bu...

Effect of Service Differentiation on Quality of Service (Qos) in Ieee 802.11e Enhanced Distributed Channel Access (Edca)

ABSTRACT  With recent advances in wireless technology, users of wireless network now expect quality of service and performance comparable to what is available in fixed networks. The IEEE 802.11e Medium Access Control (MAC) is an emerging supplement to the IEEE 802.11 Wireless Local Area Network (WLAN) standard that supports Quality-of-Service (QoS) requirements of both data and real-time applications. The IEEE802.11e MAC is based on both centrally-controlled and contention-based channel acce...

Development and Performance Evaluation of a Double-Rotor Self-Action Cassava Grater

ABSTRACT The modification of a single-rotor cassava grater was undertaken. The singlerotor grater was modified into a double-rotor self-action grater and its performances evaluated by determining its throughput capacity and efficiency. The throughput capacity was determined by grating known quantities of cassava roots in three respective runs and the time taken to grate them measured from a stop watch. The efficiency of the machine was calculated from the quantity of roots grated and quantit...
