ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with ...
ABSTRACTA comparative study was conducted among organic waste materials namely coconut fiber, hair, sawdust and woodchips as crude oil absorbents. Twenty grams of each of these materials were wrapped in a pouch and submerged into two set-ups, Set-up A: Pure Crude Oil and Set-up B: Crude Oil with seawater, for an hour. Amount of oil absorbed was gathered and recorded. ANOVA was conducted to verify if the results significantly differed. The results show that hair had the highest amount of ...
ABSTRACTIn recent times, most of the household appliances are using electric power and as such, electricity shortage has become a major problem throughout the world. Ceiling fan is one of such appliances that consume electric power. The best way to minimize the power consumption of the ceiling fan is to reduce the weight of the ceiling fan blade. Thus, this project work entails the design of a new ceiling fan blade in which case the weight and power consumption was compared to the Panasonic m...
ABSTRACTThe general approach to any design of a process plant involve an advanced network of Chemical Engineering processes. This equipment design project was carried out to design a molten salt cooler (heat exchanger) for production of 2.7 x 104 tonnes/year capacity of phthalic anhydride by direct synthesis of gaseous naphthalene.The information concerning the design of this equipment was gotten from literature review which was then used to obtain the physical properties datas. T...
INTRODUCTIONA public address system is an electronics sound amplification and distribution system with a microphone, amplifier and loud speaker used to allow a person to address a large public. The public address system consists of three main parts namely, the microphone (input transducer), amplifier and the loudspeaker (output transducer).The microphone picks up the sound and convert it to electronic signal in milivolts and this is fed to the amplifier for amplification. In this project, a d...
ABSTRACTAs the name of the project implies “Automatic Emergency Light” is an electronic system that can provide light during emergency situations i.e when mains (NEPA) supply fails. This system can provide enough light with full brightness in a given room or office. The system makes use of white light emitting diodes for the lightings. It is automatic in operation, in the sense that it can switch itself off when the battery charges full. Automatic Emergency light compri...
ABSTRACT As the name of the project implies “Power Inverter”, is an electronics system that converts DC Energy (voltage) to an AC energy. The major aim of this project is to design and construct a 1000VA Power inverter that is capable of powering loads of equivalent ratings, in the absence of power supply from NEPA or Generator. The system (power inverter) consists of the AC mains sensor section, Relay/change over section, Battery charger section, oscillator section, Driver section,...
ABSTRACTAir pollutions pollutant showed that the extent of spreading depends on the motor vehicle traffic population of the area. This pollution strongly generated through combustion of fossil fuels presents difficult environmental challenge to societies as it could degrade the environment and affect human health and quality of life. Vehicular emissions are major contributors to air pollution in urban areas as they contain harmful gases. The levels of carbon monoxide has been investigated in ...
ABSTRACTFlooding has been described as one of the most important environmental factors determining the distribution of salt marsh plants. We studied the impact of five water levels on the germination and establishment of the invasive cord-grass spartina deniflora. Plant house experiment was carried out to determine the effects of time and depth of flooding on the survival and growth of rice. Data showed that time and depth of flooding had significant effects on the survival and growth of rice...
ABSTRACTThe microbiological and organic pollutants characteristics of umuosoko stream in ikwuano local government area, Enugu state, Nigeria were carried out. Twenty water samples were collected from four different parts of the river. The pour plate technique was employed for the isolation of micro-organisms. Colonial morphology, Gram staining and biochemical tests were used for identification and characterization. The statistical analyses used were analysis of variance and standard dev...
INTRODUCTION The purpose of a control system is to produce a desired output. This output is usually specified by a command input, and is often a function of time. For simple applications in well structured situations, to control, and the controller must have the capability of reacting to disturbance, changes in its environment, and new input commands. The keys element that allows a control system to do this is feedback, which is the process by which a system’s output is used to influe...
DEFINITION OF A KEY A key is a piece of steel in inserted between the shaft and a hub of the pulley or the gear, mainly to that power. Key are always inserted parallet to the shaft axis. They are need as temporally fastening and are subjected to considerable cursing and shearing stresses. A key - way in a slut or recess in the shaft and hub of a pulley to accommodate a key. KEYS A key is a machine member employed at the interface of a pair of mating male and female circular c...
INTRODUCTIONCommunication means extending information form one person to another in a way in which it can be understood. Information and ideas in technical and scientific fields can very often be more easily communicated through sketching or instrument drawing and blueprint reading. Drawing involves describing the shape and size of an object. CHAPTER ONE PreamblesTypes of Engineering DrawingsCHAPTER TWO2.1 STAGES IN THE DEVELOPMENT OF A NEW PRODUCT 2.2 THE DRAWING OFFICE 2...
INTRODUCTIONThis work was obligated to present in one. The fundamental and practical information in the filed of the comparative analysis of the strength of concrete made from various aggregate which may be useful to people involve in civil and structural engineering and particularly, those that found pleasure in the design and related structure.Due to high cost of sand in the market the comparative analysis of strength of concrete made from various aggregate play an important rol...
INTRODUCTIONRetaining walls are structures used in providing stability for earth or materials where conditions dis allow the materials from summing its nature al slope or stabilityThere are many factors affecting or militating against the stability of retaining walls. These includes the level of water table behind the wall, size of the base of the wall and nature of the soil retainedUnder these effects of he nature of soil,. we have the angle of internal content between the particles, t...
