The aim of the work is to develop a new analytical model of liquid solidification taking into account the phenomenon of free convection in horizontal, fluid -saturated, granular porous plates and to experimentally verify the theory. This model is based on previous theoretical research and experiments of the authors of this work. In order to determine the solidification front, the measuring cylinder method was used, in which the solidification front was determined indirectly by measuring the increase in water volume in a measuring cylinder connected to the test chamber. Based on the analysis of the phenomenon of free convection of water in a porous medium saturated with fluid, the heat transfer coefficient on the solidification surface was determined, which is an important parameter from the point of view of heat transfer. It was also deemed necessary to take into account the anomalous properties of water. The results of theoretical research were compared with the authors' experimental research and presented in pictorial form. Due to the great practical importance of the issue of freezing of the ground and elements of buildings and structures, it is necessary to understand this phenomenon as undesirable for the durability of building structures.
Protective coatings for machine parts can be economically viable if the wear is localized or if the coating material has different properties than the substrate. Technological surface layers (TSLs) are applied to objects before use, while functional surface layers (FSLs) are applied during maintenance. Laser surface modification is a field of study that involves numerous research centers worldwide. By controlling laser parameters such as power, scanning speed, and pulse duration, it is possible to create coatings with various surface properties, such as surface geometry, microhardness, stress states, or resistance to wear. One of the most common and affordable techniques for surface modification is electro-spark alloying (ESA) or electro-spark deposition (ESD), which involves using a focused stream of energy similar to laser treatment. However, electro-spark deposited coatings may have drawbacks that limit their application. To address this, the coatings can be further treated with a laser, which effectively eliminates surface defects such as scratches, delamination, and microcracks. Additionally, the laser treatment seals the coating, improving its overall performance. ESA coatings have multiple applications, including protecting new elements and restoring the properties of worn elements. ESD is a proven technique for regenerating aircraft engine and hydraulic components in specialized vehicles. The production of ESD protective coatings has also found extensive use in the automotive industry. Significant research has been conducted to assess the effect of various ESD parameters on the properties of coatings. This paper aims to determine the properties of electro-spark coatings by analyzing their microstructure, measuring their microhardness, friction force, and corrosion resistance. To carry out these tests, a Cu-Mo coating (the anode) was electro-spark deposited onto carbon steel C45 (the cathode). The resulting coatings are intended for use in increasing wear and corrosion resistance.
There is an increase in cyberattacks directed at the network behind firewalls. An all-inclusive approach is proposed in this assessment to deal with the problem of identifying new, complicated threats and the appropriate countermeasures. In particular, zero-day attacks and multi-step assaults, which are made up of a number of different phases, some malicious and others benign, illustrate this problem well. In this paper, we propose a highly Boosted Neural Network to detect the multi-stageattack scenario. This paper demonstrated the results of executing various machine learning algorithms and proposed an enormously boosted neural network. The accuracy level achieved in the prediction of multi-stage cyber attacks is 94.09% (Quest Model), 97.29% (Bayesian Network), and 99.09% (Neural Network). The evaluation results of the Multi-Step Cyber-Attack Dataset (MSCAD) show that the proposed Extremely Boosted Neural Network can predict the multi-stage cyber attack with 99.72% accuracy. Such accurate prediction plays a vital role in managing cyber attacks in real-time communication.
The paper presents an analysis of the functional operational properties of multilayer coatings for use in military technology in the field of masking. The developed coating systems are characterized by operational innovation due to their small thickness when compared to those currently used by global defence contractors while maintaining the re-emission coefficient required for camouflage to be effective in the optical range. Their service life and durability were assessed in terms of functional properties based on measurements of attenuation coefficients, surface geometric structure, adhesion, specular gloss and colour parameters. The tests were carried out for coating systems fabricated in five variants: a two-layer paint system (SP1), a threelayer paint system (SP2), a laser-modified three-layer paint system (SP3) and a four-layer paint system in two variants (SP4 and SP5), with the former being modified with carbon nanotubes and the later − with spherical iron. Coating systems are characterized by low roughness and good adhesion and have appropriate attenuation coefficients for radar waves. Due to their operational properties, the developed coating systems can be used on armaments and military equipment.
The purpose of this paper is to perform unsteady hydrodynamic flow over an inclined plate embedded in a porous medium with Soret‐aligned magnetic field and chemical reaction. Once momentum, energy, and mass are equal, they can be combined using the diffusion equation to yield the dimensionless momentum/energy/mass model. Computations were performed to analyze the behavior of fluid velocity, temperature and concentration on the inclined vertical plate with the variation of emerging physical parameters like aligned magnetic field, Casson parameter, inclined angle, chemical reaction including soret parameter. The findings derived from skin friction, Nusselt number, and Sherwood number are included in the tables provided for different parameters. The results match with a special case of previously published work. From the present analysis, it is reported that the presence of angle of inclination, aligned magnetic field, and Casson fluid parameters sustains a retarding effect on velocity. The velocity decreases with increasing angle of inclination, aligned magnetic field parameter, and Casson fluid parameter. Comparisons with previously published work performed and the results are found to be in excellent agreement.
