COMMUNICATION IN VISIBLE LIGHT USING BLUE GaN µLED AND FLUORESCENT POLYMER COLOR CONVERTER
Abstract. A new method to achieve high speed visible light communication (VLC) using white light generated by a blue GaN µLED and a yellow fluorescent copolymer is presented. We generated white light suitable for indoor lighting by optimizing the ratio between the blue EL of a µLED and the yellow photoluminescence of a copolymer color […]

SINGLE-PHOTON AVALANCHE DIODE (SPAD) VLC SYSTEM AND APP FOR DOWNHOLE MONITORING
Abstract. This paper shows for the first time that the problem of continuous downhole monitoring in the oil and gas industry is effectively solved through the use of visible light communication (VLC). As a reliable, flexible and low-cost method, VLC can meet the critical need of operators to maintain production efficiency and optimize gas well […]
THE USE OF CASE-STUDY IN TEACHING PROFESSIONAL ENGLISH ON THE EXAMPLE OF A LESSON ON THE TOPIC “DIPLOMATIC SECURITY”
Abstract. The purpose of considering the application of case-study methods in the form of watching a video in professional English lessons is to develop interpersonal communication for all participants in the educational process. Indeed, in conditions of situational learning, it is very important to maintain the interest of students through the mutual exchange of information […]
THE ACADEMIC PERFORMANCE FUNCTION AND ITS STUDY
Abstract. The academic performance of the study group is tracked at each stage of the monitoring of the educational process in the university. Changes in the learning process related to academic performance require constant monitoring, adjustment, and management. In every situation or human life, for example, if we talk about health, it is better to […]

ORGANIZATION OF CHARACTER DATA TRANSMISSION WITH THE HELP OF WHITE LIGHTING LEDS
Abstract. The article proposes a data transmission system based on VLC technology using a new physical coding. The transfer of character data from one personal computer to another was realized using a white illuminating LED. When transferring data, a driver was used to control the LED. Instead of the standard physical coding approach, where one […]
