Short circuit is a key factor which drastically affects the efficiency of metal electrorefining. Infrared image of the intercell busbar region is used to perform short circuit detection. To cope with the high thermal background, a two-level short circuit detection method is designed. Firstly, with background subtraction, high intensity short circuit electrodes, as well as the background, are removed, and normal working electrodes are preserved. In the second stage, suspicious short circuit areas are sifted out by normal electrode detecting and texture period estimation. Gaussian difference filter (DoG) which is based on the human visual system is improved to match the target gray distribution. A comparative experiment indicates that the proposed orthogonal DoG outperforms the original DoG and top-hat in the accuracy of normal electrode detection. The two-level detection method in this paper is applied in a copper electrolysis plant and exhibits superiority in locating short circuits and avoiding miss detection.

“…This made it possible to significantly expand the possibilities of studying physical processes in combustion [32,33], and the use of IR thermography together with other modern noncontact research methods. Particle Image Velocimetry (PIV) allowed one to identify and evaluate the scale of turbulent structures in a flame and establish a correspondence between hydrodynamic and thermodynamic processes [34,35].…”

The paper gives an overview of experiments on the study of natural fires, carried out by the staff of the Department of Physical and Computational Mechanics of the Faculty of Mechanics and Mathematics of TSU. A number of recommendations for safe conduct of experiments are given, the requirements for measuring equipment and its use in conducting firefighting activities are indicated. It is noted that for the early detection of fires, it is best to use measuring equipment that allows you to estimate the number and size of aerosol particles in the air. To register meteorological parameters should be used ultrasonic weather stations, allowing to register the various components of flow velocity and some characteristics of turbulence.
