Authors: Kuts V. V. , Grechukhin A. N. , Privalov A. S. 
Published: December 2024

Purpose of research. The study is devoted to the study of the influence of the angle of inclination of the receiving surface with a convex and concave profile on the change in the displacement of a single deposited layer during additive shaping by an electric arc in a protective gas medium. Experimental studies on shaping on receiving surfaces with different angles of inclination have been carried out. Based on the samples obtained by electric arc welding in a protective gas medium, the displacement values of the individual deposited layers are determined. Since the angle of inclination of the receiving surface can affect the displacement of a single deposited layer during additive shaping by an electric arc in a protective environment, a one-factor dispersion analysis was performed. Methods. Methods of organization and planning of the experiment, mathematical processing of experimental results, single-factor analysis of variance. Results. As a result of the dispersion analysis, it was revealed that the angle of inclination of the receiving surface during additive shaping of products affects the displacement of a single deposited layer and is a significant parameter during additive shaping by an electric arc in a protective gas environment. In particular, it was found that the significance criterion for the slope angle is p < 0.01. In turn, for a convex surface it is p < 0.03, for a concave surface it is p < 0.004. Comparing the results, it can be seen that the criterion is more significant for a concave surface. Conclusion. It is determined that the angle of inclination of the receiving surface significantly affects the change in the displacement of a single deposited layer during additive shaping by an electric arc in the sphere of protective gas. Therefore, the angle of inclination of the receiving surface with a convex and concave profile is significant and should be taken into account when designing technological processes for additive shaping of products by an electric arc in a protective environment.

Published: December 2024

Purpose of research. Due to the growing demand for energy-saving technologies around the world and in the Russian Federation, thermal energy storage devices are interesting for research. There are various ways to accumulate thermal energy, one of them is using thermal accumulators at a phase transition. These devices will be the target of research for further development. Methods. One of the most effective heat-storing substances of phase transition is paraffin. In the process of reviewing the scientific literature, three main areas for the use of thermal accumulators of phase transition were identified: heating and hot water supply systems from traditional energy sources, heating and hot water supply systems from renewable energy sources, pre-start preparation internal combustion engines. An unpackaged heat accumulator with a phase change can be used to accumulate low-grade heat in the return pipeline of a heating system; another type of accumulator will be effective when charged from a solar energy source. To preheat the internal combustion engine in a car before starting it, you can also use a heat accumulator. Results. The review and analytical study of existing phase change heat accumulators showed that existing phase change heat accumulators based on paraffin can be improved by trying different arrangement configurations, using polymer materials to supply coolant, and looking for ways to reduce the volume and weight of their design. Conclusion. Further comprehensive study of phase transition heat accumulators will make it possible to find effective ways to use it in individual heating and hot water supply systems, as well as in internal combustion engines. Look for new directions for their application, which will be the goal of further research.

Published: December 2024

Purpose of reseach. The main goal of this study is to evaluate the effectiveness of using non-metallic meshes made of high-strength fibres in the reinforcement of folded elements. For this purpose, methods for calculating folded structures made of concrete composites are investigated, and a comparative calculation of the structure with various reinforcement parameters is performed.Methods. The study analyzes an algorithm for calculating reinforced cement structures using the limit force method with the transition from the original folded section to the reduced section. Using the method under study, we calculated a thin folded panel reinforced with meshes of various materials with a constant mesh reinforcement coefficient. Welded steel mesh, high-strength glass fiber textile mesh and carbon fiber textile mesh were considered as reinforcement. Simultaneously, the inverse problem was solved, within the framework of which the reinforcement coefficient necessary to ensure the same load-bearing capacity of the section when using different reinforcing materials was selected.Results. Sample of section reinforced with carbon fiber mesh exhibit the greatest ultimate load of 14.5 kNm . Sample of section reinforced with glass fiber and welded steel mesh exhibit ultimate load of 6.4 kNm and 1.72 kNm, respectively. Inverse problem was also solved. The reinforcement ratio necessary to ensure equal load-bearing capacity of the panel reinforced with different materials was determined. The reinforcement ratios of steel mesh (S), AR-glass textile (G) and carbon textile (C) were found as S:G:C=1:0.26:0.12.Conclusion. Reinforcement of concrete composites with non-metallic meshes has significant potential for the design of lightweight spatial structures for roofing buildings and structures. The use of high-strength reinforcing textile meshes makes it possible to achieve panel strength comparable to that of traditional reinforced concrete products. It is necessary to consider other strength calculations of folded panels reinforced with non-metallic meshes and experimentally confirm the results of analytical calculations.
A Patient-Oriented Implementation Strategy for a Perioperative mHealth Intervention: Feasibility Cohort Study

Published: December 2024

Background
Day surgery is being increasingly implemented across Europe, driven in part by capacity problems. Patients recovering at home could benefit from tools tailored to their new care setting to effectively manage their convalescence. The mHealth application ikHerstel is one such tool, but although it administers its functions in the home, its implementation hinges on health care professionals within the hospital.

Objective
We conducted a feasibility study of an additional patient-oriented implementation strategy for ikHerstel. This strategy aimed to empower patients to access and use ikHerstel independently, in contrast to implementation as usual, which hinges on the health care professional acting as gatekeeper. Our research question was “How well are patients able to use ikHerstel independently of their health care professional?”

Methods
We investigated the implementation strategy in terms of its recruitment, reach, dose delivered, dose received, and fidelity. Patients with a recent or prospective elective surgery were recruited using a wide array of materials to simulate patient-oriented dissemination of ikHerstel. Data were collected through web-based surveys. Descriptive analysis and open coding were used to analyze the data.

Results
Recruitment yielded 213 registrations, with 55 patients ultimately included in the study. The sample was characterized by patients undergoing abdominal surgery, with high literacy and above average digital health literacy, and included an overrepresentation of women (48/55, 87%). The implementation strategy had a reach of 81% (63/78), with 87% (55/67) of patients creating a recovery plan. Patients were satisfied with their independent use of ikHerstel, rating it an average 7.0 (SD 1.9) of 10, and 54% (29/54) of patients explicitly reported no difficulties in using it. A major concern of the implementation strategy was conflicts in recommendations between ikHerstel and the health care professionals, as well as the resulting feelings of insecurity experienced by patients.

Conclusions
In this small feasibility study, most patients were satisfied with the patient-oriented implementation strategy. However, the lack of involvement of health care professionals due to the strategy contributed to patient concerns regarding conflicting recommendations between ikHerstel and health care professionals.

Unmanned aerial systems have been increasing in demand for a wide range of operations, including the rapid growth of advanced navigation and communication. One of the most important things in designing an Unmanned Aerial System (UAS) is to ensure the system's stability, such as the UAS itself. This study was conducted on an in-house medium altitude long endurance (MALE) UAS aircraft. It is focused on analyzing the longitudinal stability of MALE UAS. A mathematical approach was used to analyze the longitudinal stability. A series of wind tunnel tests using a scaled model of the MALE UAS is done to produce several sets of data containing longitudinal stability derivatives for various configurations. A few sets of data are chosen to obtain the stability derivatives needed. These stability derivatives are utilized to determine the longitudinal motion characteristic of the aircraft. The analysis of certain derivatives and the phugoid and short-period mode shows that the aircraft is statically and dynamically stable in longitudinal motion. The results indicated that a weight change prompted an altercation in the natural frequency of the short-period mode. The response also showed that reaching a new equilibrium state takes a rather long period after an arbitrary perturbation is initiated. The time required to subdue oscillation in axial and average velocities is more than 100 seconds. The stability in the pitch rate is reached in around 65 seconds. The time to reach stability in pitch angle response is around 65 seconds.

Published: December 2024

With the development of containerized environments, the issue of security is becoming critical for application deployments. This article provides a comparative analysis of static and dynamic methods for scanning Docker container images. Static analysis is used to identify potential vulnerabilities before container deployment, while dynamic analysis is performed in an isolated environment at runtime, ensuring product reliability. The work of Trivy, JFrog Xray, Snyk, and Docker Scout scanners is compared, and their advantages, disadvantages, and effectiveness in different conditions are emphasized. Trivy has been proven to find the most vulnerabilities among the scanners tested. Snyk and Xray give similar results, but Xray also checks for encryption of important data such as passwords. Docker Scout turned out to be the weakest representative, the only advantage of which is open access to results that can be analyzed without uploading an image to the server or personal developers’ computer. Particular attention is paid to static analysis due to its broader coverage of vulnerabilities, including operating packages and application dependencies. The difference in the assessment of the criticality of vulnerabilities by different scanners is demonstrated, and it is also discussed how many vulnerabilities found do not always mean a high level of risk. Based on the analysis, criteria for choosing a scanner are proposed to avoid information leakage due to unnoticed vulnerabilities.
