In this article problems faced by engineers and scientists  in developing, and characterizing solar simu...

Improving the Availability of the Onitsha-New Haven 330kv Transmission Line Availability Using Adaptive PMU-Based Insulation Defect Detector

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...

Development of a Smart Motion Detection Device for Home and Office Security Applications

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...

Smart Digital Thermometer for Covid-19 Detection

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...

Development of a Low Cost Automatic Internet of Things Extension System

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 ...

LPG Gas Monitoring and Cylinder Booking Alert System

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...

Selection Of An Electricity Tariff Plan For Mini-Grid Business Models: An Intuitionistic Fuzzy Axiomatic Design Approach

Abstract This article proposes a conceptual framework that used mini-gird business models (MBMs) to rank electricity tariff plans. The framework combines intuitionistic fuzzy set (IFS), Criteria Importance Through Inter-criteria Correlation (CRITIC), fuzzy axiomatic design (FAD) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). It considered when decision-makers specify or did not specify for MBM’s requirements. Also, this article considered uncertainty in decisi...

Power Quality Enhancement For A Standalone Photovoltaic System

A distribution network connected to rural consumers is often quite weak due to the long distance. Hence, an increase in power demand over this network will result to power quality problems. The main cause of this unacceptable situation is the inability of the power system to meet the demand of reactive power. Inductive loads are the main cause of power quality problems and they are widely used in domestic and industrial sector, contributing to inefficient use of energy. In this paper, a react...

Rodin Platform Why3 plug-in

Abstract. We briefly present the motivation, architecture and usage experience as well as proof statistics for a new Rodin Platform proof back-end based on the Why3 umbrella prover. Why3 offers a simple and versatile notation as a common interface to a large number of automated provers including all the leading SMT-LIB and TPTP compliant tools. The plug-in can function either in a local mode when all the provers are installed locally, or remotely as a cloud service. We discuss the experience ...

Chaotic Secure Communication Schemes employing Chua’s Circuit

Abstract In recent years, chaotic secure communication systems have attracted significant interest due to their higher unpredictability over conventional secure communications systems and simplicity of implementation. This study presents the modeling of four chaotic modulation techniques. The techniques are Chaotic Masking (CM), Chaos Shift Keying (CSK), Chaos On-Off Keying (COOK), and Differential Chaos Shift Keying (DCSK). Simulations were carried out using Simulink in Matlab environment to...

Chaotic Behaviours in Dynamical Systems with Application to Secure Communication

ABSTRACT Attention has recently been focused on irregular aspect of the behavior of dynamic systems. One of such behaviour models is chaos which has been widely reported as having a great potential in communications. This study aimed at demonstrating the major concepts in non-linear dynamics and chaos grid the application of these properties in communication. The behavioural modes of logistic map which is a simple dynamical system were investigated with different values of system parameters a...

Control, Automation and Monitoring Of Hardboard Production Process Using PLCSCADA System

Human necessities are increasing day by day where as the factories are running out of resources. To ameet these demands industries need to improve the quality and quantity of their production. Programmable logic controllers (PLCs) have been used for many decades for standard control in industrial and factory environments. Over the years, PLCs have become computational efficient and powerful, and a robust platform with applications beyond the standard control and factory automation. This pa...

INVESTIGATION OF SUITABLE TIME FOR THE PERFORMANCE MEASUREMENT AND EVALUATION OF MONO-CRYSTALLINE PHOTOVOLTAIC PANELS AT FEDERAL UNIVERSITY OF AGRICULTURE, ABEOKUTA (FUNAAB), ALABATA, OGUN ST

Abstract  Human existence relies on solar energy either directly or indirectly and the world at large cannot continue to exist, remain or live without the solar energy. Solar power in Nigeria can serve as a source of sustainable energy if fully utilized due to abundant availability all year round energy and its regular appearance on daily basis in the sky under a friendly environment. The maximum output current and power of solar panel used in harvesting solar energy are obtained at sola...
