ABSTRACT The over dependent on the utilization of industrially manufactured soil improving additives (cement, lime etc), have dept the cost of such stabilized soils financially high. The hitherto have continued to deter the underdeveloped and poor nations of the world from providing accessible pavement to their rural dwellers who constitute the higher percentage of their population and are mostly, agriculturally dependent. A number of researchers have studied the physical and chemical propert...
ABSTRACT The DC motor speed control system using mobile phone is a device used for controlling the speed of a DC motor. It is powered electrically to vary the speed of a DC motor. This project makes use of dial tone multi frequency (DTMF) decoder after being powered to pick the key pad tones from the GSM phone, encode the tone in binary code to the programmed microcontroller which decodes the binary code and executes the speed control of the DC motor. The speed of the motor depends on the num...
ABSTRACT Security is one thing human should not joke with, especially in today’s world where crime is at a higher rate. One of the ways of providing security is the introduction of security doors in houses, companies, offices and warehouses. Security doors may prevent or control entry or exit, or they may be merely decorative. Larger doors can be used for a whole building, such as a castle or fortified town, or the actual doors that block entry through the gatehouse. Today many doors are ...
ABSTRACT Today in this digitalized world, if the fuel indicator in the automobiles is also made digital it will help to know the exact amount of fuel available in the fuel tank. The above furnished fact is considered in our project and we found out a proper solution for indicating the accurate availability of fuel in the tank digitally. An ultrasonic transmitter and receiver is used to find out the fuel level which is economic and also accurate. The added Feature in this ...
This device takes over the task of Ringing of the Bell in Colleges. It replaces the Manual Switching of the Bell in the College. It has an Inbuilt Real Time Clock (DS1307 /DS 12c887) which tracks over the Real Time. When this time equals to the Bell Ringing time, then the Relay for the Bell is switched on. The Bell Ringing time can be edited at any Time, so that it can be used at Normal Class Timings as well as Exam Times. The Real Time Clock is displayed on LCDt display. The Microcontroller ...
ABSTRACT Artificial intelligence is the study of computer or microcontrollers ability to perform task which is currently done by human. For instance, when there is an outage of a certain power supply in a particular illuminating lighting device. In that case intelligence emergency light is an electronic circuit that controls automatically the security lighting of an industrial layout according to the ambient level of lighting. In the field of security, security lighting is often used as a pre...
ABSTRACT A digitally controlled light dimmer circuit is based on the principle of power control using thyristor. The switch enables light from an electric bulb to be raised from full brilliance down or up to a high range of luminance. Owning to its construction, adequate conservation of energy is achieved. The circuit is made in various patterns depending on the manufacturer. Some have a rotary knob; some have milled edged control while others have a depressing switch or side...
ABSTRACT This seminar focuses on a low cost DC motor speed control system using a microcontroller logic pulse-width modulation [pwm] controller to control brushless DC Motor. In a digital controller of brushless DC Motor, the control accuracy is of a high level, and it has a fast response time. Here a microcontroller of 8-bit type (80CL580) will be used as the systems core controller in other to acquire an accurate logic control algorithm. The DC motor speed control has found vast application...
ABSTRACT Construction industry has complexity in it nature because it contains large number of parties such as clients, consultants and contractors. The factors that influence construction management practice differ from country to country, due to prevailing conditions. The objective of this project is to identify factors that influence construction management practice in Nigeria construction industry and elicit perceptions/ranking of the severity using relative importance index of the variou...
ABSTRACT Safety on Nigeria roads has become a thing of concern in recent times. This is as a result of numerous carnages that have characterized with Nigeria roads. This loss of lives and properties have been attributed to many factors including poor road design and defective construction practice. A road that is poorly designed, is in no doubt a threat to the safety of the road users. In this paper, therefore the way in which highway design and construction practice impacts on the safety of ...
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 A web-based information management system for national health insurance scheme(NHIS) will assist the body to have an online registration of people, health maintence organizations (HMOs), accredited heath care providers, etc. Looking at the Nigerian population, access to health insurance is denied to a certain category of people as a result of not being a government worker or not privileged to be duly informed on the operation of the scheme and how to enroll Knowing that Health insura...
ABSTRACT The traditional methods of analysis of frames are based on first-Order Solution which has many simplifying assumptions, the chief of which includes negligence of shear and axial deformations. In its formulation, the existing second order solution neglected the contribution of shear deformation as well as the contribution of axial force in the curvature of the element. In the attempt to estimate the effect of shear deformation, A, Chugh super-imposed to the conventionals (traditional)...
ABSTRACT ( . 1, Routing of solid waste collection vehicles in Nigeria poses a challenging task I because ol' attitudinal and liapliazard infi-a structural problems to contend with. 1, New decision procedures for solid waste collection problem are introduced in this study. 'The problem objective is to minimise the overall cost, which is essentially I based on tlie distance travelled by vehicle. The study proposes heuristic methods to generate a feasible solution to an extended Capacitated Chin...
