ABSTRACT Till date IVR systems are used in the areas of telephone banking, tele-voting etc but our project is a step towards even broader aspect and usage of IVR systems i.e. in college automation. Through our project “microcontroller based automation system”, we are trying to replace the conventional notice board by a well automated device. The circuit enables the user to hear as well as read the information being announced through a speaker and an LCD.If the announcements regarding any...
ABSTRACTThe world today is moving ahead at a very fast pace. Some of the very common examples of fast moving objects are aeroplanes, high speed cars and many more. In our everyday life we come across many fast moving vehicles and so it is very important to measure the speed of these vehicles.This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although wi...
ABSTRACTThis design is aimed at providing a system that has the capability of recharging batteries after use. The design is to incorporate an auto charging cut off circuit that operates when the battery is fully charged to avoid damaging the device and also a low voltage circuit which prevents the system from damage should in case the battery voltage level drops to a particular preset value. This design is used to charge batteries not exceeding 36volts and a lineup of batteries not exceedin...
ABSTRACTThis system “MICROCONTROLLER BASED AUTOMATIC HAND DRYER SYSTEM” comprises of many modules which are: The Sensor/Input Unit, Microcontroller Unit and the Output Interface. The sensor detects when the hand approaches the nozzle. Once the approaching hand is detected, the hand dryer produces a very hot to dry the hand as well as displaying “busy” on the display unit of the design. Once the hand is removed, the hot air automatically stops and the display unit displays “idle”. ...
INTRODUCTION This project presents the design and construction of a computer based program used to control office appliance. It is based on a Graphic user interface (GUI) programming language (Visual Basic 6.0), Parallel Port Interactive Mode, Opto-Coupler Isolation of the computer from the appliance to prevent damage to the system should a fault develop in the appliance. The implementation was based on the interaction of the computer with electronic appliance via the 25 Pin Centronic...
This work is based on automatic changeover switch. If there is failure in main power supply it will automatically change to auxiliary power supply such as generator. This project is based on electromechanical changeover with the use of magnetic contractors, relay,and circuit breaker.
ABSTRACT This project involves the development of a console that allows multiple inputs (3 inputs) and a single output to a screen through the use of software. The micro controller which serves as the ‘heart’ of the hardware was encoded using C programming language. These lines of code enable the micro controller to switch to the selected signal when the remote is pressed or one of the buttons is pushed.
ABSTRACT Deregulation is the removal or simplification of government rules and regulations that constrain the operation of market force. In course of studying the effect of deregulation, various economic model will be applied to data gotten from the Nigerian National Petroleum Corporation NNPC for efficient and workable economic policy that will bring a sustainable development to both the sector and the country as a whole. This work analyzes the various implications removal of subsidy wil...
ABSTRACT Industrial waste water treatment covers the mechanisms and process used to treat water that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. Water is a natural and inorganic solvent with the composition of hydrogen and oxygen only (H20). When there is addition of other organic or inorganic, substances (high levels of nutrients, nitrogen and phosphorous) in water which may come as a re...
ABSTRACT The production and analysis of “Ngu” extract for temperature and water requirement for leaching of caustic alkali is the basic objective of this project. The production was carried out by using unit operations and also using the female inflorescence of a palm fruit (Eleasis Guineesis) as raw material. The female inflorescence of palm fruit was size reduced from original dimensions to maintain particle size characteristics. The size reduced bunches were dried at room temper...
ABSTRACT This project “production of plane mirror using local raw material” is meant to study the possibility of producing plane mirror using sand rich in silica as its major local raw material.Plane mirror is produced by casting one side of a sheet glass. Presently in Nigeria, sheet glass is not used easily produce and as such, the local raw material used in the in the production of plane mirror in this product backing paint. The facilities for the production include spraying gu...
ABSTRACT This project is aimed at producing black and brown polish of good quality. For clearity, polish is a substance rubbed on the surface of materials to make them smooth and shiny. Polish has being of immense importance in protecting leather surfaces and enhancing their beauty.To produce a standard polish, hard waxes such as carnduba wax, candelhla wax and palm wax; semi-hard waxes which include, paraffin wax and ozokerite; solvents like tupentine and naphtha; dyes and dryers are esse...
ABSTRACT This report aimed at determining the presence and removal of mercaptan sulphur in kerosene using colour indicator method. It is known that impurities such as free sulphur, sulphur dioxide, mercapters, funing materials etc. are found in petroleum products. Consequently,absorbents like molecular sieve, calcium oxide and even activated carbon could be used to trap these impurities, thereby making the product impurity free.The afficac of the absorption using calc...
ABSTRACT Interface on petroleum product in multi-purpose pipeline system refers to as the zone of demarcation between two products where mixing occurs. Generally, interface is a boundary layer, so the boundary between two products when they are pumped in succession is known as interface.In Nigeria Petroleum Industries like NNPC (PPMC) make use of multi-purpose pipeline system. This is where interface comes in petroleum products. Interface as defined above plays a lot of economics impor...
ABSTRACT Blender 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 preliminary drawings with deta...
