ABSTRACT Analysis of plane truss structures based on the assumptions that (1) members are connected at joints by frictionless pins and (2) loads are applied at joints only have become a norm not minding the facts that our practical trusses are always constructed by connecting members to gusset plates by welds, rivets, or high-strength bolts and loads may not necessarily be applied only at the nodes, have made such assumptions not to yield quite precise results. By the nature of practica...
ABSTRACT Solar cells based on ITO/InP have been shown to possess a remarkable potential for space applications. The determination of the terrestrial and simulated-space stability of any type of solar cell is important in obtaining the payload power requirements of a spacecraft which will be powered by that type of cell. In this work, a preliminary investigation of the terrestrial stability of ITO/InP cells has been performed. The cells were stored in the dark for six months in thermostaticall...
ABSTRACT The development and utilization of energy has led to environmental degradation with associated health hazard. Hence the trust of this project is to optimize energy mix in a reliable, affordable, available, safe, efficient, effective and sustainable way at control cost subject to environmental constraints. In other to achieve the desired goal, optimization model is derived with unit cost of each of the various energy sources as the objective function and environmental impact as const...
Abstract Reliable electricity supply is essential for development. As a result, demand for electricity has continued to increase globally, occasioned by the fact that electricity is highly portable and can be transformed from one form to another to meet needs. In Nigeria and most developing countries, electricity supply from the public utility is not only insufficient but highly erratic. The effect of this is adverse on critical and sensitive infrastructure that depend on uninterrupted power...
Abstract Torsional vibration in Internal Combustion Engines is an important phenomenon occurs due to excitation loads, cycle-to-cycle variations results from the force the burnt gases and to change in inerita forces generated by reciprocating parts during convertoin of rotary motion to the linear one . This conversion leads to twist torque on the crankshaft which, in turn, leads to high stresses causing its damage. The importance of the present study stem from the fact that this phenomenon c...
ABSTRACT Blind people daily encounter many difficulties such as walking on the road, finding right path. In this project the interactive cane comes as a solution to enable them to identify the world around by integrate the traditional white cane with circuit consisting of microcontroller and ultrasonic sensors to detect obstacles ( forward ,above knee ) and pits .In addition there is water sensor to detect water on the ground. The result of ultrasonic sensors is alarm with different rings fo...
ABSTRACT Heart Rate Variability (HRV) Represent one of the most promising markers which represent anon invasive way of measuring autonomic nervous system(ANS), it describes the variation over time of both instantaneous heart rate and the interval between consecutive heart beats. Previously traditional methods had been used for calculating heart beat as using hand with time , and after the appearance of the new method and devices those depend on computer program the HRV analysis become more ea...
ABSTRACT Businesses (Manufacturing, Merchandising or Service Delivery) have similar organizational structures like Administration, Human Resources, Marketing, Accounting and Customer Care/Public Relations. Stand alone software products have been developed to enhance operations in each of these business. The business management system software developed in this project is aimed at integrating these software products into a single system that will provide solution to different management...
Abstract With the increase in vehicle production and world population, more and more parking spaces and facilities are required. In this research a new parking system called Smart Parking System (SPS) is proposed to assist drivers to find vacant spaces in a car park in a shorter time and save effort. The new system uses sensors to detect either car park occupancy or improper parking actions. Features of SPS include display of available parking spaces, payment facilities and different types o...
ABSTRACT Biomass is naturally abundant in rural communities but is generally considered to be a waste in most developing countries of the world where it is used inefficiently in its traditional form. The effective utilization of these materials offers many advantages among which is a renewable and sustainable energy feedstock for the production of solid fuel – briquettes - for heating applications. Attempts have been made in developing machines for commercial briquetting of biomass in deve...
Abstract In areas in which there is little or no communication infrastructure or the existing infrastructure is expensive or inconvenient to use, wireless mobile users may still be able to communicate through the formation of an ad hoc network. This research investigates the overall performance of the Optimized Link State Routing (OLSR) protocol on Voice over Internet Protocol (VoIP) applications in Mobile Ad hoc Networks (MANETs) under IPv6 environment. Using VoIP over MANETs takes advantag...
ABSTRACT This project is a farm operation monitoring system using a microcontroller device that gets the status of the farm by using the following factors: soil moisture, temperature, light and humidity and send the status of the farm to the user using a SMS alert notification system all at a given time. In the field section, the Farm monitoring system was built around three sensor modules, and will be programmed using to read in data from a monitoring device that will be attached to the sen...
ABSTRACT Agriculture is considered as the basis of life as it is the main source of food and other raw materials. This report describes an IOT Irrigation Monitoring and Control system wherein, the user can monitor and control the supply of water from a remote location. The system makes use of a concept called TOT (Internet of Things). This enables the system to be connected to the internet using a Wi-Fi module. An Arduino Uno board was used to send the control signals and connect to the desi...
ABSTRACT In today's world, speech recognition has become very popular and important, speech plays a vital role in human to system and machine communication, speech signal is transformed from analog to digital wave form, which can be understood by the system or machine. , , The development of a speech recognition system for toilet flushing using Mel Frequency Cepstral Coefficient (MFCC) technique, has become a necessity as the physically challenged ones (handicap), individuals suffering from ...
ABSTRACT Language is the basic medium of communication and it is ultimately important because it is the primary means through which humans have the ability to communicate and interact with one another. Translation has been made very important so as to bridge the gap of information inequality. A lot of countries and organizations rely on human translators to disseminate information but human translators are limited in terms of speed, insecurity and high cost, therefore the demand for faster a...
