HOME CONTROL SWITCH AUTOMATION USING GSM COMMUNICATION

ABSTRACTThe 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 ...

CONSTRUCTION OF MICROCONTROLLER BASED VEHICLE SPEED ALARM.

ABSTRACT The project is based on Construction of microcontroller vehicle speed alarm system which automatically warns the driver by activating a panic alarm which is triggered on when the driver exceeds the speed limit set in the system which also stops the alarm when the speed is reduced below the set speed limit. A speedometer system is used to monitor the speed of the car. The voltage output of the speedometer system is used to set the time the alarm comes on. The other component part...

CONSTRUCTION OF MICROCONTROLLER DOT MATRIX DISPLAY SYSTEM

ABSTRACTThe microcontroller based display board is an advert system that displays information based on a specific purpose. The system is designed to enable the viewer know the designers aim.The system comprises of different blocks of functional circuit that are put together to achieve the desired aim. These blocks include; the power supply section, the control section, the demultiplexer section and the display unit. The power supply unit is the section of the system that ensures that the syst...

CONSTRUCTION OF A BLENDER

ABSTRACTBlender is an electric machine for size reducing soft food or liquid mixture.  Blender is some time called liquidizer consists of a glass jar or jug containing a steel blade assembly at the base driven by a small electric motor.Construction of blender was done based on the principle of size of reduction using electric motor as the major driver force.  During the construction of blender, we adopted different stages which includes:i.    The production of prelimi...

DESIGN AND IMPLEMENTATION OF ONLINE VOTING SYSTEM INCORPORATING FINGER VEIN SENSING

ABSTRACTVoting is a very important process in the Nigerian political system.  It is one of the means and most effective method of ensuring a legitimate government through popular participation.  To enthrone sound democracy and stability in the political system in Nigeria, a system of rig-free voting has to be put in place. Online voter registration systems supplement the traditional paper-based process, by which new voters fill out a paper form that is submitted to election official...

Production and characterization of briquette from chat residue

Briquette is a block of compressed materials suitable for burning. Briquettes can be made from low cost materials such as old newspaper, any bio mass wastes and agricultural residues. They can be used as fuel instead of charcoal, firewood or mineral coal and costs less. Depending on which materials were used to make the briquettes, they may burn cleaner than charcoal. Finally, turning waste materials into a fuel source is attractive because it reduces waste as well as reducing the demand for ...

Advanced Fine Finishing Process

ABSTRACTThis technology is so helpful in our everyday life. This paper dealt extensively about the latest technology which is useful for finishing materials with a very high precision. These latest processes are known as Advanced Fine Finishing Processes. In this paper, we gave a thoroughinsight into some of these processes.With the demand of stringent technological and functional requirements of the parts from micro- to nano-meter range, evolution of ultra-precision finishing processes becam...

Automatic Temperature Control In Vacuum Brazing Furnace Using P.L.C

ABSTRACTBrazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel as based filter material in air or atmosphere the braze joint will porous and braze strength is not achievable. To avoid the presence of oxygen while brazing, either inert gas furnace or vacuum furnace can be used. Vacuum furnace is superior to inert gas controlled by furnace ...

Production Of Biodiesel From Jatropha Crop

ABSTRACT:    The interest in using Jatropha  curcas  L.  (JCL)  as a feedstock for  the  production  of  bio-diesel  is  rapidly  growing.   The  properties  of  the  crop  and  its  oil  have  persuaded  investors and policy  makers to consider  JCL  as  a  substitute  for  fossil  fuels  to reduce  greenhouse&nbsp...

Biostimulation Of Crude Oil Contaminated Soil Using Local And Foreign Stimulants

ABSTRACT Bioremediation is an important technology for the restoration of oil polluted environments by indigenous or selected microorganisms. In general, the rate of biodegradation depends on the number and types of micro-organism, the nature and chemical structure of pollutants to be degraded and the environmental conditions. In this study, the efficacy of the biodegradation potentials of foreign (  PETROX HC 500, PETROX HC 600, PETROX HC 100, PETROX HC 1150 AND PETROX HC 339 ) and loca...

Cryogenic Science And Engineering

   ABSTRACTThis report is intended for a general insight into cryogenics. Different individuals may have faint ideas about what cryogenics are as much is not known here in Nigeria about what cryogenics are and this report work clearly gave a deeper knowledge of cryogenics     Chapter one gives a brief history of cryogenics and the various cryogenic temperatures that have been achieved since 1800 to 1965. Chapter two gives a general knowledge of the fundament...

Design of a Hudraulic Escalator

ABSTRACTAn escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of usage are; shopping malls, airports, transit systems, convention centers, hotels, and public buil...

Thermodynamic Principle Of Energy Conversion

ABSTRACTEnergy conversion engineering (or heat-power engineering, as it was called prior to the Second World War), has been one of the central themes in the development of the engineering profession. It is concerned with the transformation of energy from sources such as fossil and nuclear fuels and the sun into conveniently used forms such as electrical energy, rotational and propulsive energy, and heating and cooling. A multitude of choices and challenges face the modern energy conversioneng...
