BACKGROUND: Artificial intelligence (AI) is a system based on machine learning of neural networks. AI structure resembles nerve tissue, having the so called neurons, i.e. mathematical codes. A neural network has three levels, including the input laye

The method of magnetron sputtering in an argon, nitrogen, and ethylene atmosphere was used to obtain Ta-Zr-Si-B-C-N coatings. The coating structure was studied using scanning electron microscopy, energy dispersive and X-ray phase analysis. Mechanical

A new algorithm for detecting linear infrastructural objects in aerial photos is presented. It is assumed that these objects pass through the whole image: beginning at one side and finishing at the opposite one. It is also assumed that the altitude o

We propose a new fast and reliable algorithm of parametric curves detection on images. In our approach as well as in many other approaches based on the Hough transform, we analyze the set of points obtained by an edge detector. Edge points are collec

The interaction of a gas jet (He, Ne, Xe) with the incident laser plasma from a solid target [B, (CH2)n, (CF4)n] removed by ≈1 cm is investigated. Line spectra arising from the charge exchange of multiply charged plasma ions with rare-gas atoms are

We discuss the potentialities of aperiodic multilayer structures for the reflection of XUV radiation, including attooptical applications. Pilot samples of aperiodic normal-incidence broadband focusing multilayer mirrors are employed in a stigmatic tr

A 'clean' (debris-free) pulsed soft X-ray (12.5–25 nm) source excited by nanosecond neodymium laser pulses in a pulsed xenon jet was optimised. The source efficiency in the λ < 15 nm range is improved due to the weakening of photoabsorption in the
