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...

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...

A Fault Detection And Protection Scheme For A 200 Mva Transformer Using Fuzzy Logic

ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of change of current with time have been identified as the input variables, duly represented in the programme as “Error” and “Error-Dot”...

Development Of Countermeasures Against Some Internet Security Threats

The internet is an unavoidable infrastructure that can provide enormous benefits to the average person/organization. Unfortunately there are elements whose goal is to interfere with the smooth benefits of it to users for either mischief or criminal intent. This has spawned a bourgeoning industry that focuses on developing and deploying countermeasures to the products of hackers and other internet pirates. Internet security is configured around several structural features that may b...

Modeling Modelingand Parameter Extraction of a and Parameter Extraction of a 214 MVA Turbo- 214 MVA Turbo-generator driven by DC generator driven by DC Motors during Off- Motors during Off-li

Abstract This thesis aims to extract d-axis machine parameters of a 214 MVA high-speed turbogenerator using well-established offline techniques. MATLAB/SIMULINK tool has been utilized to model the generator and perform sudden short-circuit (SSC) tests. Because constant speed operation of the generator is vital consideration for the accuracy of SSC tests for parameter extraction, this thesis has employed an arrangement of 2 DC motors operating alongside a drive system, which is configured...

Electric Vehicle Charging Infrastructure with Three-way Automatic Switch

Abstract Electric Vehicle (EV) technology is one of the steps in battling climate change through electrification of transport systems. Great advances in energy to size and energy to cost ratios have presented a great opportunity allowing all auto manufacturers to jumped for the idea of electrification as the future of transportation. The journey for better charging technologies is still a very important area of research. Among the main challenges in electrification of transport is inade...

PRIVACY-BY-DESIGN FOR INTERNET OF THINGS(IOT): IMPLEMENTING USER AUTONOMOUS OPTIONS IN A SMART HOME SCENARIO

Abstract In traditional Internet of Things (IoT) systems, users are unable to authorize and/or deauthorize the collection of user data. Hence, the problem of the absence of user autonomy in IoT systems. The project aims to tackle this problem by suggesting a human-centered privacy-by-design option in the design and implementation of IoT systems. It aims to prioritize the need for the privacy of the user in designing IoT systems. It proposes to do this through the provision of user autono...

A LOW COST ANTI-THEFT TRACKING SYSTEM FOR ELECTRIC VEHICLES

ABSTRACT A vehicle tracking system is any technology that can be used to access the location of a vehicle; either in real time or offline. However, for many car owners, especially on the continent of Africa, vehicle tracking is a luxury which only a few people can afford. Many people are struggling to get a car in the first place. Analysis of vehicle theft data done in South Africa showed that most of the vehicle theft in the Southern African country are as a result of poor security sys...

Store Management System To JIT

AbstractMy project is to improve JIT store management system from manual to automated system.   Which is used to avoid problem faced by store keeper when store material manually. Store is the place where many varieties of materials are kept for the purpose of work. So at a time of storage is hard to write in document all material listing by their name, id, model, price and quantity; and is also boring to search specific material from whole material for human being but is easy for computer t...

Speed control of marine diesel engine self-tuning based on fuzzy PID control and genetic algorithm PID

The mathematical model of diesel engine and its speed regulation system are presented and computer simulation is conducted in Matlab software. Simulation results verify that the proposed method improves the control accuracy of speed of diesel engine. A fuzzy PID hybrid controller and a Genetic Algorithm PID of parameter self-adjusting is put forward in this paper.Chapter I: Case Study 3Statement of Problem......................................................................................

SQUARE WAVE TO SINOUNSIDAL WAVE FORM

The availability and stability of electrical energy is necessary for domestic and industrial use. But unfortunately the monopoly which the Power holding company of Nigeria (PHCN) enjoys in this country is not in favor of the electricity users, because the supply is never constant and damages occur due to inconsistency of this supply is very enormous. However, millions of naira’s are lost every day in the commercial and industrial sectors, and even at the same time a lot of Lives are wasted ...

Design and construction of 36W automatic solar street light using Solar panel, charge controller, led and with battery

Design and construction of 36W automatic solar street light using Solar panel, charge controller, led and with batteryCHAPTER ONEINTRODUCTION1.1 Background InformationElectricity is a general term comprising of a variety of phenomena resulting from the presence and flow of electric charge. These include many phenomena, such as lightning, static electricity, and the flow of electrical current in a cable. In addition, electricity comprises less familiar concepts such as the electromagnetic fiel...

MODELING OF CORE LOSS IN INDUCTION MACHINE

AbstractInduction machine account for about 60percent of the electrical consumption in industrial countries; hence a huge energy savings could be achieved by even a small increment in the machine efficiency. Improving the designs of induction machines requires accurate quantification of the machine losses. A significant portion of the losses in electrical machine is caused by the core losses in the magnetic materials. The physical mechanism of core losses is still an open problem, and most of...
