In the paper we represent experimental results of the research of human vision sensitivity to pulsed radiation of discrete light emitting diodes (LEDs) of different colors when their dissipated electrical power was the same. We used color components of RGB LED matrix and determined the values of the dissipated power at which resultant LED radiation was perceived as white light. These power values...
The article deals with theoretical and practical issues of the implementation of professional activity analytical evaluation information technologies. The focus is on new methods for presenting and processing data in the activity description and evaluation tasks.
The goal of the work is to define the probability factor of particles movement in a gas-dispersed turbulent flow. The object of the research is the description of harmful impurities transfer process in the atmosphere with the help of mathematical modelling of variability of gas and aerosol composition of atmosphere. Another object is assessment atmospheric impurities on the environment. The novelty...
