This abstract discussed the implementation of speech recognition applications to control the on-off electrical device of speech. The work is divided into two modes. Offline mode and online mode. To use voice commands to turn on-off electrical device. Which the words sound as a statement. The speech sounds in offline mode is saved in SOPARE voice and speech mode are saved online in Google Assistant via the microphone. Then process the Raspberry pi 3 board to send data to the wireless transceiver module to control the power on-off. From testing the control system for opening and closing electrical devices with sound it was found that the sound test in the offline mode of the power-on-off control system with sound the accuracy of 96 percent of the voice command and the accuracy of the lamp according to the voice command spoken 100 percent accuracy. Sound tests in the online mode of the power-on-off control system with sound the accuracy of 8 7 percent voice commands and the accuracy of the lamp according to the voice command spoken 100 percent accuracy. The power-on-off control system with sound. Can be used to effectively control the opening and closing of electrical equipment. Only the user speaks the voice commands as needed and can immediately turn on-off the electrical equipment. Helps reduce steps and shorten the time of use making it more convenient

This project presents the development of wearable device for logging cow behavior using IoT technology. This project aims to develop the device that can collect the cow’s behavior and to identify the current position of cow. The accelerometer and ultrasonic sensors are used to measure walking behavior and sitting behavior respectively. The current position of cow is measured by GPS module. The measured data will be shown and stored in IoT platform. According to the experiments the developed systems can measure the behavior properly with human acting as a cow. Moreover the developed system can show the current position of the cow and message when the cow is out of area. In the future it is planned to implement the developed system with the actual cow in real situation

This research is to study and develop writing aids for learning disabilities in children. These children usually have shot span attention. The writing disability can be detected in the early age such as children in pre-school or kindergarten but it will be amplifies when the children are in grade school. The research shows that these writing aids for learning disabilities in children can help children to be more focus and pay longer attention to the teacher. The main problem in learning disabilities in children is that these children don’t have the ability to tell the different between the letters that look similar to one another. After using these writing aids for learning disabilities in children and slowly teaching them step by step to the 5 year old and up children these children shows some improvement. These children spend longer time with writing aids for learning disabilities in children because of their light color and the sound that the aids make. The children seems to be enjoy using the aids and this can also help the teacher in the class room.

This paper presents the method to reduced electromagnetic interference from electronic drive for LED lamp to achieve the TIS standard No.1955-2551. According to standard it must have been tested for magnetic field compatibility that are included Magnetic Field Emission: ME Conducted Emission: CE and Coupling Decoupling Network: CDN. The 3 LED lamp which defined as Type A B and C were tested. Each lamps has 16 watt electric power and was different electromagnetic interference of electronic drive. After that the reduce electromagnetic interference circuit has been designed for low frequency. This circuit test was based on Conducted Emission test only. The integrated design was preferable to reduces electromagnetic interference for LED lamp drive device type A to the TIS. standard No. 1955-2551. That design circuit was been trialled in LED lamp drive device type B and C in order monitor efficiency of reduce electromagnetic Interference. The results showed that design circuit can reduce electromagnetic interference from LED lamp drive device type A and B to the standard. For LED lamp drive device types C the design circuit can reduce electromagnetic interference but it still has not achieve the standard.

This project report proposes a design and construction of model of protection equipment for three-phase transmission line by voltage relay for protect. By protection equipment can protect the transmission line from over voltage and under voltage on the transmission line The objective of design and construction model of protection equipment for three-phase transmission line. The objective for construction model of protection equipment for three-phase transmission line. For understand power system protection principles. And understand using to protection equipment for three-phase transmission line correct. From experimentation model of protection equipment could protect over voltage and under voltage on the transmission line
