A distribution network is one of the main parts of a power system as it is connected directly to the load center and can act as a microgrid during an islanding operation. The concept of integrating both renewable and distributed energy sources at the distribution level is currently of great interest for power system engineers. Further research by power companies and engineers on applying better techniques...
There are different kinds of technologies being used to improve the communication opportunity of children with verbal challenges. Portable communication devices provide the facility to the users for customizing applications according their needs. Besides, the usability and costing range of these portable communication devices make them less condemning for the users. On the other hand, communication...
Energy structure reforming and implementation of renewable energy generation in the regional grid usually depend up on the availability of resources, socioeconomic structure, political issues and environmental concern. In this sense a developing pacific Island country like Fiji acquires huge opportunities and potentials for implementing renewable energy. However the challenges that prevent developing...
The reliability of electrical power network is the driving force for the development of a country Nowadays most electrical power industries and companies are working for the better satisfaction of the customers while considering the associate cost. Utility companies must have precise information concerning system performance to achieve these goals, consequently guarantee the assets maintenance. The...
This research looks at the design and construction of an Arduino controlled prototype of irrigation system based on a mobile platform/vehicle for agricultural sector. The vehicle is designed to be controlled through an Infrared (IR) remote control with a range of at least 5 meters. The vehicle uses an ultrasonic sensor to avoid collisions and obstacles. This system is mostly manually controlled and...
With the increased development of mechatronics system and scarcity of land space, this paper introduces and prospects an engineering application to solve or reduce the mentioned issue by designing and implementing automated multi-level car parking system. The paper discusses the research antiquity, brief model methodology, software implementation, design analysis and recommendations.
Nowadays Geographic Information System (GIS) and Remote Sensing (RS) techniques are used in different area of research for monitoring, collecting and analysis data from various geographical locations. Due to the vast increase in global industrial output, rural to urban drift and the over-utilization of land and sea resources, the quality of water available to people has deteriorated greatly. The high...
Nowadays Internet of Things (IoT) and Remote Sensing (RS) techniques are used in different area of research for monitoring, collecting and analysis data from remote locations. Due to the vast increase in global industrial output, rural to urban drift and the over-utilization of land and sea resources, the quality of water available to people has deteriorated greatly. The high use of fertilizers in...
In generally, predictive maintenance of induction motors is well suited for small to larger scale industries in order to reduce downtime, increase efficiency and reliability. In this paper, the vibration and temperature of the induction motor is analyzed in order to gather specific information that can predict motor's bearing failure. Well analyzed vibration signal easily shows the difference between...
Nowadays rate of vehicle theft is very high all through the world and the situation are even worse in developing country. Therefore, protection of vehicles with an intelligent, reliable, effective and economical system is very important. The existing technologies for vehicle security have a number of limitations including high false alarm rate, easy deactivation and high cost. In this research an...
This paper describes the design and implementation of an automatic PCB drilling machine that can be used for drilling prototype PCB boards. The Model design is described first, and then the paper moves on to the electronic hardware designing phase where each component is explained and then moves on to explain the program logic written for the automatic PCB drilling machine.
Liquid levels are measured in a variety of industrial applications, and are often measured manually, which can be labor-intensive as well as time-consuming. Rapid advances in electronic technologies have made a variety of inexpensive sensing, monitoring, and control capabilities available. A mechatronic design solution is produced to solve a practical problem faced by Generation Strategic Business...
In this paper an intelligent system for remote patient physical condition monitoring service module for an Intelligent Robot Swarm for Attendance, Recognition, Cleaning and Delivery (iWARD) [1] is reported. The system algorithm and module software is implemented in C/C++, and the Orca robotics [2] components use the OpenCV[3] image analysis and processing library. The system is successfully tested...
To accomplish control tasks, an emerging innovative method of automation is voice control. In conjunction with Lab VIEW [1] and Windows Speech recognition [2], the two most human interactive activities; drawing of curtains and switching on and off of lights are controlled. This will help in improving living standard by making living easier for elderly people, reducing frustration and increasing independence...
The trend of current brain computer interfaces (BCI) seek to establish bi-directional communication with the brain, for instance, recovering motor functions by externally controlling devices and directly stimulating the brain. This will greatly assist paralyzed individuals through bypassing the damaged brain region. The key process of this communication interface is to decode movements from neural...
A major thrust in brain machine interface (BMI) is to establish a robust, bi-directional direct link between the central nervous system (CNS) and artificial devices (e.g. medical implants, artificial organs, neural stimulators, robotic hands, etc.) for cybernetic interface and treatment of a range of neurodegenerative conditions. Significant effort has centered on support of motor control through...
Decoding of movement related neural activity is a key process required for brain computer interfaces or bio-feedback. The subthalamic nucleus (STN) is involved in the preparation, execution and imagining of movements. This study therefore aimed to decode subthalamic local field potentials (LFPs) related to movements and its laterality, left or right sided visually cued movements. STN LFPs frequency...
Tongue movement ear pressure (TMEP) signals have been used to generate controlling commands in assistive human machine interfaces aimed at people with disabilities. The objective of this study is to classify the controlled movement related signals of an intended action from internally occurring physiological signals which can interfere with the inter-movement classification. TMEP signals were collected,...
