Metal silicides play a significant role in the preparation of ohmic contacts and Schottky barriers on silicon. The formation of ohmic contacts is carried out by applying a metal film with a thickness of ∼ 100 nm to silicon, followed by annealing at temperatures of 400–600 °C, as a result of which there is a reaction between silicon and metal with the formation of silicide. With this technology, silicon diffusion leads to instability of devices. In this regard, the authors developed an improved technology for the formation of silicides of refractory metals to obtain ohmic contacts. Ion implantation allows, due to ionic mixing, forming nickel silicide on the surface of the samples when heated. It is important that, with an increase in the radiation dose, the formation of Ni2Si silicide slows down. This effect can be explained by the formation of a dielectric Ni3Si2. Similar phenomena were observed during the bombardment by oxygen and nitrogen ions.
The robustness of the security algorithm is one of the most important properties that determines how difficult it is to break it. Increasing the robustness of the algorithm directly affects the degree of secrecy when it is used for confidential transmission. The paper analyzes the steganographic algorithm Least Significant Bit, represents a method of counteracting the algorithm of the "visual attack" and statistical methods used against stego-containers generated using the LSB algorithm. To prove the increase in resistance, the study used the PSNR index, Chi-square test. The proposed technique involves the use of a uniform distribution and compression method. The paper presents the results of computer experiments demonstrating the effectiveness of the proposed technique.

Data analytics using neural networks is a modern trend in scientific research. One of these scientific tasks is the use of artificial intelligence in the time series research and forecasting. The paper considers the results of experiments on the use of one-dimensional convolutional layers in a neural network within the framework of the meteorological (wind speed) time series data classifying task. The improving of the forecast accuracy by adding convolutional layers is shown, which in the considered real problem reaches 9 %. Several variants of architectures for building a model with convolutional layers with an estimate of the accuracy of their prediction are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
