Purpose: The purpose of this paper is to analyse the obtained experimental data, which is advisable to use to verify the thermophysical model of the thermal regime of a separate premise while using ceramic electric heating panels for heating purposes. Design/methodology/approach: The experimental studies were carried out at the scientific thermophysics laboratory with the help of up-to-date equipment...
Purpose: of this paper is to provide operational tension control of fabric on knitting equipment using ultrasonic contactless transducers to improve the quality characteristics of the finished product. Design/methodology/approach: It has been established that the amplitude of ultrasonic waves passing through different zones of the textile material can be used to determine the tension of the knitted...
Purpose: The purpose of the paper is to substantiate the new method of measuring the voltage-current characteristics of solar batteries based on the use of a digital oscilloscope and a special linear sweep device. Design/methodology/approach: To solve this problem, a test bench was developed on the basis of a solar radiation simulator. Findings: Practically it is proved that within the duration of...
Purpose: The ultrasonic amplitude method for controlling the surface texture density of textile materials was first studied and used. Design/methodology/approach: For the first time, the surface texture density has been determined. The research was conducted using the ultrasonic method, rather than by mathematical calculations, which made it possible to invent a new approach to contactless quality...
