Design Of An Electronic Siren Circuit

Siren is a device that produces loud noise. They are the means communication. Sirens can be seen in emergency vehicles such as police cars, ambulances and fire trucks.Generally, sirens are used as indication or warning. There are different circuits to produce different sirens. The word siren first originated in Greek mythology and was also later used to refer to mermaids. Language and literature have used the word siren as indicative of dangerous temptations. The sire...

Design, Development And Testing Of A Liquefied Petroleum Gas Powered Tomato Dryer With Water Energy Stotage

Despite high levels of good quality tomato production in Kenya, about 40% of the produce goes to waste.  This loss is attributed to glut during the harvesting season, poor feeder roads which lead to inaccessibility to the market centres as well as bruise damage during transport.  This translates to a huge financial loss to tomato farmers.  Preservation through drying technology can help in reducing this loss.  Therefore, this study was initiated to investigate the pe...

Nitrogen Doping Effect On Tin-Selenium Thin Films For Phase Change Memory Applications

ABSTRACTPhase change materials have been widely used in optical and electronic storage due to rapid and reversible phase transition between amorphous and crystalline states with remarkable resistivity and optical contrasts. More recently these materials have been identified as suitable candidates for phase change random access memory (PCRAM) applications due to their potential for high scalability, low power and fast speed operation. Despite these superior properties and enormous potential, h...

Automation of Waste Segregation Via Sensors by Using PLC

Abstract With the growing population rate, the amount of waste being produced is also increasing at a very fast rate. These days in our environment waste management is one of the major problems, the best solution has been proposed to solve this problem is segregating this waste and recycle it. But segregating it manually is complex, dangerous and utilizes more human efforts, cost and time. The proposed system designed to separate five types of wastes into respective bins automatically...

An Assessment Of Embedded Power Generation In Nigeria

ABSTRACT In the last decades, the power industry has had a gradual and steady change from the centralized bulk system (grid) where power is injected to the transmission network from generator to a more decentralized system where power is injected directly to a distribution network (embedded generation). Nigeria is not left out in this trend. In this assessment study, the Siemens’ PSS/E software is used to run the Newton-Raphson load flow program to see the effect of EG on loss reducti...

Greenhouse Wireless Monitoring and Control System Based on Sensor Network

ABSTRACTIn this thesis, an embedded system which is closely monitored and controlled theclimate parameters such as humidity, temperature, and light of a greenhousesbased on wireless sensor network on a regular basis round the clock forcultivation of crops or specific plant species which could maximize theirproduction was presented. The designed system comprises beside the sensorsfrom microcontroller, monitor, wireless communication based on XBee andrespondents such as fan, heater and p...

A Comparison between Proportional-Integral-Derivative and Fuzzy Controllers for Water Tank

Abstract Fuzzy logic is a paradigm for an alternative design methodology, which can be applied in developing both linear and non-linear systems for embedded control. One of successful application that can use fuzzy control is liquid level control. This control system keeps developing from time to time to replace the ordinary system which applies mechanical functions in its control in order to improve the system reliability. In order to find the best design to stabilize the liquid lev...

Reliability Centered Maintenance (Rcm) For Asset Management In Electric Power Distribution System'

ABSTRACTAbility to use electrical energy when required is one of the fundamental presumptions of a modern society, and the introduction of complex and sensitive machines and systems into the network had increased the need for high reliability of supply [1]. Deregulation and competition are forcing improvements in efficiency and reductions in cost while customers are becoming more sensitive to electrical disturbances and are demanding higher levels of service reliability. Since a typical...

Reliability Centered Maintenance (Rcm) For Asset Management In Electric Power Distribution System

ABSTRACTThe purpose of Maintenance is to extend equipment life time or at least the meantime to the next failure.Asset Maintenance, which is part of asset management, incurs expenditure butcould result in very costly consequences if not performed or performed too little.It may not even be economical to perform it too frequently.The decision therefore, to eliminate or minimize the risk of equipment failuremust not be based on trial and error as it was done in the past.In this thesis, an ...

Reliability Evaluation Of Secondary Distribution System In Nigeria: A Case Study Of Ayetoro 1 Substation, Aguda, Lagos State

 ABSTRACT A power system is set up basically to meet the demands of the customers. However, interruptions which are largely unavoidable contribute to the unavailability of power and thus prevent power system from achieving this. In most cases, it is the sustained interruptions that greatly affect both the utility company and its customers. Hence, it is necessary to find means of determining which component failure contributes most to the unavailability of the distribution s...

Overcoming Barriers To New Learning Technologies In A University Setting: The Case Of Covenant University

The university has currently invested a lotof funds in the acquisition of relevant and contemporary e-learning technologies, su...

Application Of Common Management Information Protocol (Cmip) In Atm Network Bandwidth Allocation System

Asynchronous Transfer Mode (ATM) of transmission is designed as a Broadband Integrated Services Digital Network (B-ISDN) transfer mode that supports a wide range of traffic classes with diverse flow characteristics. ATM guarantees different quality of service (QoS) demands placed on a network by different services (traffic types). The above powerful feats could be well achieved in ATM network with the application of an efficient and effective network resource management system. This the...
