ABSTRACT Microcontroller based remote control system is a project design of a system that uses infra red transmission and reception principle to switch on or off other appliances. It is a wireless mode of switching appliances to a desired state. When a number is pressed in the transmitter section, the receiver section decodes the signal and utilizes it in controlling the desired appliances. Several functional blocks of circuit are put together to ensure that the design works as the designer ...
ABSTRACT Flooding has been described as one of the most important environmental factors determining the distribution of salt maize plants. We studied the impact of five water levels on the germination and establishment of the invasive cord grass spartina denifora. Plant house experiment was carried out to determine the effects of time and depth of flooding o the survival and growth of rice. Data showed that time and depth of flood had significant effects on the survival and growth of rice. �...
ABSTRACT This project has been design and fabricated with special economical needs for small scale baking industries, wholesalers and distributors who impact this type of baking even from outside the country to su0pply the customers. And in view of the scarcity and high cost of gas and electricity in the country and also smoke release when using firewood for drying and preserving fresh fish by some matters at home, restaurant fast food shop etc, the pressurized kerosene oven have been fabric...
ABSTRACT As a result of modern development in Science and Technology, most of the large scale industrial used machine were now modernized to simple small and efficient machines. Some of these machines were either operated manually or the aid of electricity. For this reason, big metal sharpening machine was here reduced to simple term, which can be operated manually such as file and grinding machine for production firms and homes. This machine performs the same functions as the large i...
ABSTRACT The aim of this paper is to get a best performance by an ice block/cube making machine of refrigeration with suitable time. In present day hotels, resort and bar require more ice in very less time. So, to solve this problem and control the required time to ice formation, we construct an ice cube making machine. In present days, in market this machine is available with very high cost. So we try to make it at optimum price. Ice making machine consists of four key components; the evapor...
Abstract Power failure or outage in general does not promote development to public and private sector. The investors do not feel secure to come into a country with constant or frequent power failure. These limit the development of industries. In addition there are processes that cannot be interrupted because of their importance, for instance surgery operation in hospitals, transfer of money between banks and lots more. This paper presents the design and construction of an automatic power chan...
ABSTRACT Transportation is a requirement for every nation, regardless of its industrial capacity, population size or technological development. The Nigerian transport systems, right from inception, were poorly designed and are unable to scale up to meet greater demand, a design flaw which causes traffic congestion on roads, overstressed railways, faltering airfields, and mass-transport blind spots. Overall there appear to be market impediments which operate to limit the extent to which Nigeri...
ABSTRACT The project dealt on the production of yam flour from yam chips. The yams were peeled and washed, 100grams samples coded sample A to G were subjected to two different drying conditions. Some were dried using the sun drying method while the others were dried through oven drying method kept at constant temperature of 500C, sodium bi-carbonate was added to some of the samples, all these were done to obtain a flour with the best colour and texture quality. From the results obtained, it w...
ABSTRACT The effect of concentration of hydrochloric acid on hydrolysis of cellulose (saw-dust) to glucose was studied on this research project and the steps obtained to achieve this project involved treatment of saw-dust (cellulose) with different concentrations of the acid at constant temperature of 80° (350k) for 30mins. This was followed by glucose analysis, some analysis or experiments were done on acid hydrolysis in order to study the effect of (HCL) acid on the hydrolysis of cellulose...
The major aim and objective of this design [of a patient heartbeat and temperature monitor using RF.] is to help the doctors and family members to keep track of the heartbeat condition of their loved ones [as well as their body temperature] in the case of an abnormality in the health condition (for those with heartbeat defects and those that run excessive high temperature beyond normal). If any varied change takes place, it is notified. This notification through RF. Channel would to take an a...
ABSTRACT The advantage of cellular communication like GSM technology is a potential solution for such remote controlling activities. GSM-SMS technology can be used to control household appliances from remote places. Remotely, the system allows the home owner to monitor and control his house appliances via his mobile phone set by sending commands in the form of SMS message and receiving the appliances status as well. This system provides ideal solution to the problems caused in situations when...
ABSTRACT A comparative investigation was undertaken to determine the head loss coefficients for horizontally mounted and vertically mounted orifices using a Fluid mechanics and Heat transfer trainer developed in Nigeria. Experiments were carried out observing the procedure and the discharge of the flow of water was collected to obtain the volumetric flow rate and also read off the right and left limb of the horizontal and vertical manometers at different set points. The experimental measureme...
The scope of the project covers aspects like the features of automatic three phase selector, its applications, and its operations. Its advantages and its components. Finally, it covers the importance on the need of automatic three phase selector and contributions toward a greater sharing load balance and a better three phase power distribution and monitoring for domestics consumers. INTRODUCTION As the growing population of human race widens the gulf between energy supply and energy demand, ...
The main aim and objective of this project is to design and build and arc welding machine that operates on 36vdc at variable frequency which of benefit to urban area. This reduces the weight and size of the transformer use for welding. To have an arc welding machine that is more efficient which produce neat welding. INTRODUCTION Welding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two...
ABSTRACT It has become inevitable that there would be communication and due to the inherent limitation of the human voice, the public address system came to being. A public address or “P.A SYSTEM” is an electronic amplification system with a mixer ,amplifier and loudspeakers, used to reinforce a given sound , e.g a person making a speech, pre-recorded music ,or message and distributing the sound throughout a venue . The voice signal is passed through a microphone , which converts the sou...
