Diagnostics of a shipboard cable by measuring the dielectric loss tangent
Authors: Vlasov A , Buev S 
Published: June 2022

Abstract
Until now there has not been created a system to assess the residual resource and to predict the probability of shipboard cable failure during its operation by non-destructive methods. Periodic high voltage tests are prescribed by various guidelines. As a result of such diagnostics, the damaged section is identified and the entire cable route is replaced. Obviously, this technology does not prevent an emergency situation, does not provide information about the residual resource, and finally, worsens the properties of an already aged cable exposed to high voltage. Insulation quality control on ships is of great importance and significance. The question arises about the suitability of one or another cable route for further work after long-term operation. That is why the issues of predicting the service life of a cable and assessing its current technical condition are relevant. Modern technologies make it possible to obtain materials with improved characteristics; however, currently rubber-insulated cables are the most common. In this work, diagnostics of the state of a shipboard cable is carried out by determining the dielectric loss tangent of its insulation. This method can be used along with traditional methods for technical audit of shipboard cables, such as testing the hardness of the cable sheath, infrared diagnostics of electrical equipment. In this case, the conclusion about the current state of the cable and the forecast of its service life, in the opinion of the authors, can only be made on the basis of the results of comprehensive diagnostics performed by several methods.

AbstractThe annual increase in cargo turnover to the Far Eastern seaports contributes to the optimization of the railway infrastructure in order to increase the level of throughput and processing capacity of the Baikal-Amur Mainline and Trans-Siberian Railway facilities. JSC Russian Railways pays special attention to these issues. Organization and promotion of car traffic through the formation of freight trains using the connection technology, “virtual coupling”, heavy and dual trains that move on an ongoing basis is one of the innovative methods for increasing the carrying capacity for highly loaded sections and directions at a level of utilization of their throughput of 0, 8 or more. Under these conditions, the organization of efficient power supply of railway sections and facilities is the main factor influencing the value of the throughput capacity of transport infrastructure facilities. The article presents a technical justification for the measure aimed at increasing the throughput and processing capacity of a section of a railway line, taking into account the stability check of the devices of the traction power supply system. The predicted parameters of the operation of the traction power supply system of the railway line section are given with a promising train schedule.

Published: June 2022

AbstractThe paper deals with the problems of building structures with certain values of stability parameters based on the corresponding values of material parameters. For modeling, a passive experiment is used based on archival information for building structures. An algorithm using forecast models is built. Its main stages are given, they are indicated in the diagram. The algorithm is based on statistical approaches. The constructed forecast models for stone natural building materials, for binding materials, for forest materials are presented. During the construction of the regression model the authors proceeded from the independence of the experiments, as well as the fact that the nature of various random components remained unchanged in all experiments. The built models may be used to forecast changes in design parameters when the selected characteristics change.

Published: June 2022

Abstract
Analytical description of vibration loads of the complex construction structure is considered as a system of masses connected by means of viscoelastic springs. To take into account the rheological properties of the spring material, the Boltzmann-Volterra principle is used. A mathematical model of the problem under consideration has been developed, which boils down to the solution of a system of nonlinear integro-differential equations. A solution method based on the use of quadrature formulas has been developed and a computer program has been compiled on its basis. The results are shown as graphs. Influence of nonlinear and rheological properties of spring on amplitude and phase of mass oscillations is investigated.

Published: June 2022

Abstract
The paper deals with the surface properties of aqueous two- and three-component organic solutions (water-acetone; water-1,4-Dioxane; water-acetone-1,4-Dioxane). A modern installation, K-100 tensiometer, was used to measure equilibrium surface or interfacial tension, contact angle, etc. The du Noüy ring and the Wilhelmy plate methods were used to measure the surface tension. It shows that the surface tension isotherms for a ternary system do not contain any features uncharacteristic of the surface tension isotherms for lateral binaries. The findings made it easy to specify the adsorption of surface-active agents in water. It shows that the nature of the ternary adsorption isotherms qualitatively coincides with the binary adsorption isotherms, which leads to the conclusion that, once used together as surfactants, organic substances (acetone and 1,4-Dioxane) in water does not enhance the surface activity of each other.

Abstract
A method of automated control of human temperature in public places is proposed, which allows determining people with elevated temperature immediately at the control point. To develop the technique, an experimental stand was designed and implemented in a rack with six built-in infrared sensors. To recognize a person with an elevated temperature, an artificial neural network was used in the form of a multilayer perceptron, at the input of which there were IR sensor data. The conducted experiments showed that the trained model based on the F1-metric efficiency of 0.89 to 0.94 determines a person with an elevated temperature.

Abstract
The article theoretically examines the choice of the most optimal of the possible trajectories of cargo in the process of moving goods from one place to another, placing them in the most optimal shape and size, taking into account the characteristics of the cargo. At the same time, using the method of mathematical modeling, the position of objects in space was determined using the functions of the Cartesian and polar coordinate systems. For optimal planning and management of the placement of goods, as well as transport operations along any spatial trajectory, the matrix method of mathematical modeling of these processes was used. Practically all possible cases of cargo movement were investigated and a mathematical expression was formed taking into account the geometry and kinematics of their placement in the given volumes. Based on the results of theoretical studies, three conclusions were drawn

Authors: Klyuev R V , Guzueva E R , Bulatov Yu N 
Published: June 2022

Abstract
In the article, based on the application of the rank analysis of the technocenosis, mathematical modeling of electricity consumption by consumers for the production of hard alloys is carried out. Two methodological levels of research in the field of energy-saving and power consumption are presented. At the same time, it was found that rank analysis allows you to streamline information, effectively predict power consumption by individual objects to identify dynamics, and visually represent objects with abnormal power consumption. The analysis of the results obtained confirms the efficiency of using the H-distribution for obtaining mathematical models of power consumption of Noah and Pointer castes in the production of hard alloys. For the first time, the regularity of changes in electricity consumption by technological equipment was established, which is described by an adequate mathematical model in the form of a damped harmonic function. The resulting model is recommended for use in an automated dispatching control system for electricity consumption for the purpose of short-term forecasting of electricity consumption.

Published: June 2022

Abstract
In the conditions of agricultural production, electrical equipment is affected by a large number of unfavorable factors; therefore, the role of its technical operation increases sharply. Maintaining the operational reliability of electrical equipment at the required level is ensured by the timely implementation of their scheduled maintenance and repairs. The implementation of these measures in the conditions of agricultural enterprises is associated with certain difficulties, since electrical equipment is located in a number of areas in agriculture, remote from one another at a considerable distance. Statistical data show that a significant amount of working time is spent on transitions and transfers, which sharply reduce the labor productivity of workers in maintenance units. The article deals with problems of using mathematical programming methods for choosing the optimal routes to transport maintenance units to service electrical equipment. The method for finding the shortest route for moving maintenance units to service electrical equipment of agricultural facilities has been developed.

Published: June 2022

Abstract
Currently, several countries already invest on the application of drones for different scopes. These purposes are mainly civilian and military and some of these include the presence of water as search and rescue, inspection of pipelines, getting a bird’s eyes view over oil spills or structural integrity monitoring of bridges. For this reason, an interesting feature for drones is their ability to maneuver in fluids with different density as air and water. This research topic, shows strong scientific potentiality but it also represents a great challenge from scientific and technical view point: i) aeronautical propeller for drones in water must generate reverse thrust or braking force through an off-design rotation in off-design condition (different fluid’s density); ii) the propeller rotational velocity in water is generally one order of magnitude lower than the one for air application requiring the motors to be properly desing to meet such a wide operational range. In this paper, an experimental campaign aimed at the performance quantification of a three-bladed propeller for drone propulsion in water has been carried out in a towing tank. In particular, the generated forces are acquired through a load cell for different advance ratios J provided by varying both rotational regime and free stream velocity. The results show expected losses in the performance for the off-design rotation in terms of both thrust and efficiency. At low rotational speeds, higher values of efficiency are presented for small advance ratio. The maximum efficiency increase for higher RPS and it’s slightly influenced by small variation of propeller disk angle.
Non-contact techniques based on a vision system for the inspection of composite material components: analysis of the influence quantities
Authors: Chiominto Luciano , D’Emilia Giulio , Natale Emanuela 
Published: June 2022

Abstract
In this paper two different approaches, based on a vision system, are compared for the inspection of a carbon fibre piece, realized using a tow filament winding process. The defect of interest is the surface void percentage, which can strongly influence the mechanical and functional characteristics of the component. The approaches differ in the method of image processing: the first is based on a colour threshold setting; the second is based on a semantic segmentation algorithm. The comparison between the two techniques allows the identification of the main causes of variability, and the individuation of the advantages and limits of each one, which make them more or less suitable for use, depending on the specific application. The preliminary results show that both methods are promising for in field use, provided that the causes of variability are identified and kept under control.

Abstract
In the frame of the CleanSky 2 MONNALISA project, a wind-tunnel campaign is planned to test a tail-plane model of a large passenger aircraft by using different measurement techniques. Wind-tunnel test results obtained over a systematic series of model geometries will be used to thoroughly validate a low-order numerical method based on physical modelling that will be developed in the project to evaluate the non-linear aerodynamic characteristics of aircraft lifting surfaces. The present paper describes the main results of the infrared thermography measurements performed in the first wind-tunnel entry to be used to tune RANS solvers and for the fine calibration of the low-order numerical method.
Directional transport of droplets impacting on superhydrophobic opening triangular groove surfaces
Authors: Li Yunlai , Lu Chenguang , Liu Yahua 
Published: June 2022

Abstract
Directional droplet transport is of great importance to various processes including heat transfer, water harvesting and microfluidics. Here, a facile superhydrophobic opening triangular groove surface was proposed, and the directional transport behavior of droplets impacting on the surface was observed. The results show that the essence of the directional transport on the opening triangular groove surface can be attributed to the interaction between the impinging droplet and the groove sidewall, and the directional transport distance is regulated by the contact area during the interaction. Further, by controlling the depth of triangular groove, the triangular opening angle, the impacting point position and the Weber number, the contact area between the droplet and the groove sidewall during the interaction can be changed, leading to the variation of directional transport distance. This study provides a new method for directional droplet transport on superhydrophobic surfaces and offers more options for the manipulation of droplet behavior.

Published: June 2022

Abstract
Improving the cycle life of silicon-based anodes is extremely important to the development of Li-ion batteries. Nano-silicon / graphite / Nitrogen-doped carbon composites are prepared as hybrid anode material in this work. The nano-silicon particles are distributed in the graphite framework, which improves the electrical conductivity of the composite. The amorphous nitrogen-doped carbon layer of the composite could be a buffer structure for the volume change of Si while providing a fast transport channel for lithium ions and further enhancing the electrical conductivity of the composites. The specific capacity of the composite electrode is 656.5 mAh g-1 at 500 mA g-1. The capacity retention rate is 91% after 100 cycles. The composite electrode could deliver a specific capacity of 497.3 mAh g-1 after 200 cycles even at a large current density of 1A g-1.

Abstract
In order to better develop and utilize the low-grade vanadiferous titanomagnetite concentrate with high titanium (LVCHT) and provide reference for the treatment of similar minerals. Oxidation process and kinetics of the LVCHT were investigated in this study. The results show that LVCHT presents weight loss at temperatures less than 600 °C, which is attributed to the removal of moisture and volatile components. Above 600 °C, the weight gain of LVCHT is due to the persistence of oxidative behavior, and the oxidation process is most likely controlled by external diffusion, and the associated activation energies (Ea) and the value of k

Authors: Kasal Taylor , Sabol Kyle 
Published: June 2022

Abstract

Purpose
Escape rooms are effective educational tools for engaging learners and may serve as a strategy for medication safety training to increase perceived learned safety measures and knowledge retention. Escape rooms are lifelike environments in which participants work together to solve a succession of puzzles to escape a locked room in the allotted time. Novel medication safety training modules such as a pharmacy escape room allow medical errors to be simulated in a team-based, controlled environment focusing on system improvement to establish a culture of safety. This project was conducted to improve medication safety knowledge using a novel pharmacy escape room training module piloted within a large, integrated pharmacy department.

Summary
Several pilot groups of 2 or more pharmacy employees took part in a virtual medication safety escape room as part of a training module at Advocate Aurora Health between January and March 2021. Participants included pharmacists and pharmacy technicians employed at Aurora St. Luke’s Medical Center, Aurora Sinai Medical Center, and Pharmacy Integrated Clinical Services. Assessments were administered before and after completion of the escape room module to evaluate medication safety knowledge and perceived learned safety measures by comparing scores. A total of 101 employees participated in the pharmacy escape room, with an average escape time of 42 minutes. Overall assessment scores before completion of the escape room module ranged from 20% to 86.6%, while those afterwards ranged from 33.3% to 93.3%. Participant feedback was positive, with reports that the novel escape room training module was more engaging and interactive than the alternative online self-paced learning modules.

Conclusion
Virtual escape rooms can be used as a novel medication safety training module to increase medication safety knowledge and allow medical errors to be simulated in a controlled environment. Incorporating high-reliability tools and tactics into development of the escape room can promote safe medication practices and reinforce principles of high-reliability organizations.
