This thesis is aimed at improving the availability of the New Haven-Onitsha 330kV transmission line byusing an adaptive PMU based insulation defect detecting and location scheme. The exposed nature ofoverhead power lines makes overhead power transmission lines very vulnerable to various kinds of faults.Insulation-related faults contribute reasonably to the number of faults experienced in overheadtransmission lines. These faults cause outages in the network and reduce the availability of thetr...
Anatomical variation in the human body presents a complex challenge to design a universal antenna for all. The presence of the human body in close proximity to the antenna also presents a challenge as the near field strongly couples with a lossy medium. Other challenges include design of an antenna that is small in size without affecting its radiation pattern, efficiency, gain etc. In this work design of a biomedical antenna for cancer treatment using voxal parameters for doing SAR (specific ...
The aim of this paper is to develop, implement and test an effective and practical working solution to a smart motion detector for LPWAN technologies using appropriate software and hardware platform. The smart motion detection system consists of a Raspberry Pi, an LCD display, PIR sensors, and wires. The hardware design collaborates with Python programming by being installed on a Raspberry Pi, and it is a key function to detect who is entering a room. The proposed smart motion detector wi...
During the COVID-19 epidemic, taking temperatures has been a major focus. The aim of this project is to implement a prototype of a cheap and high reliability digital temperature measurement device with the aid of Arduino Nano, Infrared temperature sensor (MXL90614), OLED 128 X 64 (0.96-inch screen size), IR sensor and buzzer. This thermometer uses an infrared sensor MXL90614 to detect the body temperature and then sends the reading to the microcontroller. If there is no human presence nea...
This project is intended to provide a solution to a company's problem of developing a smart motion detection device for home and office security applications. The company intends to deploy 100s of these motion detectors throughout the Greater London Area. As a result, each motion detector will require a low power wide area network (LPWAN) wireless interface. Unlike traditional motion detectors, which detect only motion, the proposed motion detector will be able to detect motion direction (...
The aim of this work is to develop a prototype of a low cost automatic internet of things extension system that looks like a regular extension system but can be operated automatically. The extension system is controlled and monitored with the use of a smartphone application. The node MCU, ESP8266, 9V 1A power adapter, breadboard power supply USB – 5V/3.3V, 5V 4-channel relay, and 1602 LCD with I2C are used in the design consideration and execution. The solution is low-cost, and it ...
As we know, nowadays issues in the agriculture field are a major concern. According to the Union Minister of Agriculture and Farmers Welfare Narendra Singh Tomar, 5,579 Indian farmers died by suicide in 2020. There are many conflicting reasons for farmer suicides which are mentioned by Activists and scholars but high debt burdens, crop failure, mental health, and personal issues have been some of the most common causes amongst them. So, what is the solution that would work in farm...
ABSTRACT This project is aimed at explaining the Design and construction of a digital wall clock with a calendar. It give report on how we can achieve this aim and the primary objective of this work is to bring a vibrant digital clock display to everyone located within the vicinity where the clock is being installed, and the importance of clock is to tell time and date, so you can meet up with events and assignments, these are just few importance of CLOCK. In developing co...
Abstract The main aim of this research is to determine how energy improvement, efficiency and conservation can be achieved in industry such as the cement plant. Energy, is an essential ingredient for socio-economic development and economic growth. The objective of the energy system is to provide energy services. Energy services are the desired and useful products, processes or indeed services that result from the use of energy, such as for lighting, provision of air-conditioned indoor clima...
ABSTRACT Managing passwords is a significant problem for most people in the modern world. Passwords are a critical part of information and network security. Passwords serve as primary authentication method to protect user accounts but a poorly chosen password, if compromised, could put the entire network at risk. Many users do not understand why good passwords and password management are important for information systems. “We’re secure! We use passwords!” How many of us have heard...
ABSTRACT This project focused on how one can safely keep the house safely locked through minimizing the access to its door unit, monitoring whoever is trying to open the door and providing an alert to the security agencies in case he/she is proved an intruder by the system. The work is arranged mainly in five chapters, Chapter one includes the introduction of a system. Chapter two discusses the literature related to the system, Chapter three illustrates the methodologies used in coming up wit...
Temperature and pressure are quantities of great importance in various applications such as integrated circuit (IC) manufacture and vacuum coating just to mention a few. Therefore, their accurate measurement is inevitable. However, it is tiresome to measure and record these quantities manually by pen and paper when operating a thin film deposition system. This approach is not only time consuming but also causes human errors on the measured physical parameters. To solve this problem, an automa...
Digital signal compression in the recent past has become the mainstay of the basic technologies of multimedia due to the bandwidth and storage limitations inherent in networks and computers. The change from circuit switched to packet switched systems in the telecommunication infrastructure in the past few years, has reflected on the way Pulse Code Modulation (PCM) signal which in essence is a raw audio signal, is carried in present systems. The purpose of this study was to design an applicati...
LPG is widely used in our everyday life. It should be handled with care as it is highly flammable which causes а fire or explosion. The above circumstances can be overcome by implementing techniques for detecting accurate gas leaks. The main aim of this paper is to put forth an IOT gas management system that will be able to sense gas leakage and fire detection. Whenever leakage of gas is detected, the user will be alerted through SMS and call so that the user can turn off the gas valve immed...
In the recent past the use of renewable energy as an alternative source of energy has increased considerably. The solar cells modules manufacturing technology is becoming more reliable and economical. The feasibility of photovoltaic solar energy as an alternative source of energy has become real. The low efficiency and the weather condition dependency give room for improvement of this technology to extract maximum power for different environmental conditions. Therefore, the current–volt...
