Published: March 2023

After ISO 5500x series standards were issued back in 2014, a body of literature on asset management and asset management system has been growing. However, implementation of asset management system and its certification have not attracted much research attention. In practice, asset management system is not so widely embraced by top management, even though it supports organizations to realize value from the assets while balancing risk and opportunity, cost and performance. Hence, an interesting research question is arising, i.e., what are the key factors influencing top management’s decision to either implement an asset management system or not. After introducing a theoretical background, the paper suggests research methodology and a conceptual research model. The results of the future research should allow for a better understanding of the top management’s decision-making process related to asset management system implementation, and indicate potential areas to be addressed in the future to provide guidance to decision makers.

The Possibility of Implementing Blockchain Technology within Energy Companies
Authors: Backović Nemanja , Ilić Bojan , Mitrović Dušan
Published: March 2023

In the energy industry, contemporary solutions are constantly applied and are always welcome if they reduce the total operating costs of power plants or affect the reduction of environmental pollution. In addition to smart processes for the production of electricity and heat, the change in the relationship between energy producers and consumers is also observed through the framework of innovative blockchain technology. Given that the energy sector is very complex and that there are many actors in the electricity supply chain, it is very difficult to ensure transparent and reliable monitoring of the activities of all participants. Intermediaries are also involved in the energy trading process, whose business engagement contributes to the increase in the price of energy for end users. Blockchain technology has the potential to increase the transparency of monitoring energy flows within the supply chain and to ensure a higher degree of trust between participants in the electricity market. Consequently, this paper provides an overview of the possibilities of applying modern principles of blockchain technology within the business of companies from the energy sector. The paper systematically describes the way in which the blockchain affects the improvement of business performance of energy companies with the aim of solving the most important energy challenges of today, such as doing business in the conditions of the energy crisis and reducing the negative impacts of climate change.

Stroškovni model uporabe energentov v času dinamičnih cenovnih razmerij in zelenega prehoda
Authors: Balantič Zvone , Balantič Branka , Jarc Kovačič Branka
Published: March 2023

Throughout modern history, there have been fluctuations in the prices of energy products due to complex economic situations. Each crisis leads to the development and focus of technology in search of current alternative sources. The energy situation in Slovenia is also very dynamic, so it is understandable that everyone is looking for an optimal way out of the economic vortex. We limit ourselves to the energy supply of a single family house for heating purposes. The cost model is based on the use of the most commonly used energy products in Slovenia. We live in a country rich in forests, where biomass is the most frequently used energy source. Despite the impression that biomass is a cheap energy source in rural areas, we find that the use of a heat pump is the most justifiable investment in all conditions and environments, while also keeping in mind the unobstructed green transition.
Imagery: A Review
Authors: ÖZTÜRK Güneş
Published: March 2023

Modern neuroscience has shown that relaxing images cause the brain to release high levels of serotonin, dopamine, and oxytocin, which reduce anxiety, block cortisol, and increase neuroplasticity. Modern medicine positions human beings as passive, helpless, in need of external aid and in need of repair. However, man should be seen as a being with physical and spiritual power that can repair himself far beyond this passive role. The common point of all the studies examined in this study is that imagery, which is an internal skill, can be used as a low-cost and effective mental therapy tool. Some studies have described imagery as a more effective method than pharmacological interventions. It is seen that the application of imagery is widely used in many diseases such as psychotic disorders, cancer, asthma, migraine, hypertension, immune system diseases, mental disorders such as anxiety and depression. It is seen that the imagery technique, which is thought to work as a defense mechanism and drive satisfaction according to psychoanalytic perspective, is widely used in fields such as mindfulness-focused therapy, cognitive behavioral therapy, and dialectic therapy. This review, first of all, mentions the use of imagery and imagery in history, and then describes current research on imagery applications on different diseases. In addition, it was written to emphasize the lack of research on the mechanisms by which this personal and internal power, which is thought to affect the efficiency of the treatment, regardless of which physical or psychological help is sought, and to encourage new research.
Postpartum Paternal Depression: Its Impact on Family and Child Development
Authors: DEMİRCİ Özge , INAN Emine
Published: March 2023

The postpartum period is when parents undergo great changes and gain new responsibilities. Factors such as the changes that come with having a baby, not meeting the expectations about parenthood, having a child with a difficult temperament or health problems, or relational problems can be quite challenging in this period. These problems can deeply affect the psychological well-being of the parents. Although studies on depressive symptoms of mothers during pregnancy and postpartum are at an important level, studies aiming to examine the psychological state of fathers for the same period are still limited. However, perceptions that postpartum depression develops due to hormonal changes during pregnancy have been reshaped by the findings that this situation may also develop due to psychosocial factors. Relatedly, the number of studies on postpartum depression experienced by fathers has increased over time. Results of those studies show that fathers' psychological state also influences their parenting and the development of children. Fathers may experience paternal depression due to a lack of social support, economic conditions, relationship dynamics, and changing living conditions in the postpartum period. This situation may cause fathers to avoid parenting duties, spend less time with their children, be unable to cooperate with the mother, and have anger problems or deterioration in the relationship with the mother. The effects of depression on individuals' parenting styles negatively affect child-parent attachment and may cause children to develop emotional and behavioral problems. Therefore, it is very important to examine fathers' psychological state for children's development and the healthy progress of family dynamics. This review aims to address the effect of paternal depression on parenting and child development.

Decentralized Policy Learning for Quadruped Robots Multi-Gait Control
Authors: Pu XingCheng , Zhang Congde
Published: March 2023

This paper proposes the Decentralized Multi-Critic Actor Learning (DMultiCriticAL) method for quadruped robots to overcome the multi-task gradient conflict in multi-gait learning. In this method, each leg joint angle of quadruped robots is served as the action space of decentralized learning agents rather than learning directly to control all robot joint angles. Because of the high similarity in quadruped robot local action space, the DMultiCriticAL method can avoid the multi-task gradient conflict in multi-gait learning. Compared with the conventional multi-task learning method, we exploit the decentralized learning systems to limit the useless exploration of environments by agent, not design complex reward functions to track the multi-gait reference motion trajectory. This also means we can avoid the suboptimal reference motion trajectory design. Our experiment results show that the multi-gait motion controller based on the DMultiCriticAL method can yield more stable locomotion without complex reward function designs.

Published: March 2023

Monogenic diabetes is characterized as a group of diseases caused by rare variants in single genes. Multiple genes have been described to be responsible for monogenic diabetes, but the information on the variants is not unified among different resources. We have developed an automated pipeline for collecting and harmonizing data on genetic variants associated with monogenic diabetes. Furthermore, we have translated variant genetic sequences into protein sequences accounting for all protein isoforms and their variants. This allows researchers to consolidate information on variant genes and proteins associated with monogenic diabetes and facilitates their study using proteomics or structural biology. Our open and flexible implementation using Jupyter notebooks enables tailoring and modifying the pipeline and its application to other rare diseases.
Modeling Convective Drying of Food Products:The Case Study of Yacon (Smallanthus sonchifolius)
Authors: Marques Bianca C. , Flick Denis , Tadini Carmen C. , Plana-Fattori Artemio
Published: March 2023

The convective drying of a food product whose dehydration occurs under large deformation is studied. A numerical model is proposed for solving the heat and water mass transfer phenomena while accounting for shrinkage. The finite volume method is applied; mesh boundaries move with the dry matter. Shrinkage is predicted from geometrical considerations only, hence no information about the product's mechanical properties is required. Water diffusivity in the product is assumed to depend on both temperature and water content. The approach is illustrated for cylindrical samples of yacon, associated with high water content in natura and significant volume reduction after drying. This study considers previous experimental work with a convective drying pilot unit under controlled air temperature and relative humidity conditions. Numerical results reveal, firstly, that the significant evolutions of sample volume (to about 10 % of initial value) and of total water content (to less than 5 % of initial value) are quite well represented. Secondly, despite the relative homogeneity of temperature field, the water content exhibits differences between the sample surface and its core even after six hours of drying. Sensitivity tests put in evidence the major role played by the convective heat and mass transfer coefficients. The physical model and the numerical approach can be adapted in order to predict the evolution of materials with high water content in natura, which experience large deformation during the convective drying process.

Authors: Emelianov S. G. , Bobyr M. V. , Bondarenko B. A.
Published: March 2023

Purpose of research. The research presented in this article is aimed at improving the accuracy of determining the color shade. The developed fuzzy-logical color recognition system was used as the subject of the study. The efficiency indicator was the result of calculating the sensitivity area percentage and RMSE of the developed method.

Methods. A method based on fuzzy logic has been developed and implemented, namely, on the structure of Mamdani's fuzzy inference, which consists of the following stages: fuzzification, fuzzy logical inference, defuzzification. Triangular membership functions were used at the fuzzification stage. As a compositional rule, 12 input variables were used, combined on the basis of Zadeh's compositional rule in 27. At the defuzzification stage, the area ratio method was used. The object of the study was the developed mathematical model for determining color.

Results. A mathematical model has been developed, consisting of 4 steps, which guarantees a clear definition of 9 colors and their shades. Based on the estimation of the root of the mean square error, it was concluded that the proposed model is better than traditional options. It is expressed by the fact that the developed method reacts on the interval of the entire surface of output variables, while traditional methods have dead zones to changes in input variables.

Conclusion. A fuzzy-logical color recognition system was developed. In the course of experimental studies, it was found that the RMSE and sensitivity indicators have better results in relation to other systems.

Published: March 2023

Purpose of research. Computing networks of a plurality of processor modules have existed for a long time, however, with the development of wireless technologies, the possibility of high-quality and inexpensive implementation of the idea of real-time reconfigurable computing networks (RRTCN) has emerged. The purpose of this work is to select a wireless data transmission network for the RRTCN and create an algorithm for the dynamic selection of the "master" processor module.

Methods. The research methods of the work are based on the definitions of the theory of sets and graphs. In particular, a grapho-theoretical approach to distribution is taken as a basis, supplemented by the introduction of a system of criteria for a reconfigurable real-time computing system based on a wireless data transmission protocol.

Results. In this paper, the most suitable data transfer protocol for the local RCSRV is selected, a developed mathematical model of changing a real-time computing system built on a wireless protocol is presented, and an algorithm for selecting the processor module (PM) of the RCSRV "master" is developed. The novelty of the work is the use of the distance matrix for the mathematical description of the change in the RRTCN and its use to determine the PM of the "master" in the aircraft.

Conclusion. The developed algorithm for choosing the PM of the "master" RRTCN and the mathematical model of changing the position of the PM in a real-time computer system built on a wireless protocol allows organizing the optimal choice of the PM of the "master" in a reconfigurable computing system. On the basis of the presented mathematical model, in the future, it is possible to create a full-fledged mathematical model of the RRTCN and an algorithm for placing tasks in it.

Authors: Afonin D. V. , Kochergin O. B. , Yatsun S. F.
Published: March 2023

Relevance. The development of aviation technology is associated with the development of new means that directly ensure the movement of aircraft (AF) at the airfield. To carry out ground maneuvers with aircraft, towing airfield systems (UAS) are used, which can significantly reduce noise and air pollution near the airport, as well as reduce the inefficient resource consumption of aircraft engines and provide significant savings in aviation fuel. UAS is also used when the aircraft loses the ability to move and is located on or near the working area of the airfield, which creates a serious problem leading to the closure of the airport for flights, while airlines incur significant losses.

Purpose of research. Improving the efficiency of the towing airfield system through the development of an information system. Objectives. Development of the structure of a robotic towing airfield system, drawing up a structural diagram of the ACS layout of the towing platform, design of block diagrams of the logical controller of the ACS platform.

Methods. The level of horizontal deviation of the platform from the contrast line was chosen as the setting influence determining the position of the platform in space, which is measured by analyzing images coming from the technical vision system installed on the tow truck. Results. In the course of the study, the structure of a robotic towing airfield system was developed. Based on this structure, a block diagram of the ACS layout of the towing platform was designed and a block diagram of the logical controller of the ACS platform was developed.

Conclusions. 1. The structure of a robotic towing airfield system has been developed, including a mobile tow truck, a coupling device, an aircraft, and an on-board control system. 2. An algorithm for controlling the positioning of a robotic towing airfield system based on the logical processing of signals of an optocoupler matrix has been developed. 3. Algorithms have been developed for controlling the movement of the RBAS along a given contrast line under the action of external disturbing influences of a deterministic and random type, allowing for high-precision movement of the RMB.

Practical Benefits, Challenges, and Recommendations on Social Media Recruitment: Multi-Stakeholder Interview Study
Authors: Goldman Nina , Willem Theresa , Buyx Alena , Zimmermann Bettina M
Published: March 2023

Background

The increasing use of social media opens new opportunities for recruiting patients for research studies. However, systematic evaluations indicate that the success of social media recruitment in terms of cost-effectiveness and representativeness depends on the type of study and its purpose.

Objective

This study aims to explore the practical benefits and challenges of recruiting study participants with social media in the context of clinical and nonclinical studies and provide a summary of expert advice on how to conduct social media–based recruitment.

Methods

We conducted semistructured interviews with 6 patients with hepatitis B who use social media and 30 experts from the following disciplines: (1) social media researchers or social scientists, (2) practical experts for social media recruitment, (3) legal experts, (4) ethics committee members, and (5) clinical researchers. The interview transcripts were analyzed using thematic analysis.

Results

We found diverging expert opinions regarding the challenges and benefits of social media recruitment for research studies in four domains: (1) resources needed, (2) representativeness, (3) web-based community building, and (4) privacy considerations. Moreover, the interviewed experts provided practical advice on how to promote a research study via social media.

Conclusions

Even though recruitment strategies should always be sensitive to individual study contexts, a multiplatform approach (recruiting via several different social media platforms) with mixed-methods recruitment (web-based and offline recruitment channels) is the most beneficial recruitment strategy for many research studies. The different recruitment methods complement each other and may contribute to improving the reach of the study, the recruitment accrual, and the representativeness of the sample. However, it is important to assess the context- and project-specific appropriateness and usefulness of social media recruitment before designing the recruitment strategy.
Enablers and Barriers to Self-Management of Gestational Diabetes Mellitus: A Systematic Literature Review of Stakeholder Views (Preprint)
Authors: Nair Uthara
Published: March 2023

BACKGROUND

The prevalence of gestational diabetes mellitus is rapidly increasing at epidemic proportions making it the most common metabolic disorder of pregnancy. Many disparities exist between target recommendations from various international professional organisations resulting in a lack of global consensus. Further, GDM treatment largely relies on self-management and rapid adaptations within a short timeframe. Some studies have reported women’s experiences of having GDM, but little is known how this relates to self-management.

OBJECTIVE

The aim of this study was to identify enablers and barriers for women with GDM to self-management in the current Australian healthcare system.

METHODS

In this study, 4 databases were searched and a total of 16 studies, consisting of 799 stakeholder views were finally included.

RESULTS

The single most reported barriers echoed by both healthcare professionals and women with GDM was the fractured healthcare system. This barrier far surpassed the second and third most common barriers, insufficient education, and dietary limitations, respectively. On the other hand, the most common enablers to GDM self-management were a lack of diabetes education or guidance, and the motivation to live healthier. This was reassuring as motivation is often driven by empowerment or intrinsic factors. Utilising digital health interventions provides convenience and improves health literacy thereby overcoming some of these barriers. Due to the high heterogeneity of the studies, a meta-analysis could not be performed highlighting the need for increased research in this space.

CONCLUSIONS

Although self-management of GDM remains challenging, there are motivating enablers that the healthcare system can work on to improve health outcomes for women with GDM. Empowering women to become active stakeholders, whilst also addressing better communication, alignment, and accountability is essential to enhancing GDM self—management.

Abstract: Proper positioning of antennas is necessary for wireless communication. So herewe are giving a project on an IOT based antenna positioning system that allows for remotely positioning of antennas based over IOT. The method that is used here to control the antennas position is by using Arduino UNO R3 and Servo motors. The Blynk app acts as a remote and is used to send the signal to the Arduino through the internet. The project helps to control the antenna’s positionby the user’s command. If we have android mobile with internet connection, we can easily access the antenna position. Also to monitor the environmental conditions we have used temperature, humidity and raindrop sensors.

Currently, mobile ropeways are considered as one of the promising types of rapidly deployable transport systems, which are formed with the help of two transport and reloading rope complexes based on autonomous self-propelled multi-purpose chassis combined by a single aerial carrying-traction rope system. The key problem in creating effective mobile ropeways of this type is the choice of their rational design, which allows to obtain the best tactical and technical characteristics and quality indicators as a result of the design. The article presents and analyzes possible alternative variants of single-span mobile ropeways based on mobile transport and reloading rope complexes. Based on the results of the comparative analysis, the most preferred variant was established — a single-span single rope mobile ropeway of the pendulum type with a carrying-traction rope system in the form of a closed carrying-traction rope with two parallel branches. The article considers the typical design of the most preferred variant and describes the principle of its operation, as well as lists the main components and mechanisms of the main technological equipment, which should be part of mobile transport and reloading rope complexes.

Application of topology optimization in the design of elements of load handling devices
Authors:   Bauman Moscow State Technical University, Gnezdilov S.G.
Published: March 2023

The article provides guidelines for the implementation of conceptual topology optimization. By «conceptual» is meant optimization, the result of which is not a specific design solution, but a rational topology – a structure that best transmits the given force flows. In accordance with the above recommendations, it is proposed to carry out optimization in the following sequence: determining the object of study, searching for points of application of external forces to the object and substantiating (if necessary) their most rational relative location, determining the nature of external forces at the points of their application, applying connections, taking into account other factors and analysis of the results with their possible refinement. Particular attention is paid to the issue of constructing a loading diagram for topology optimization, which, in the author’s opinion, largely determines the success of solving the problem. A correctly prepared loading diagram should take into account all the most unfavorable combinations of loads. Recommendations on the most rational construction of loading diagrams are given. The recommendations given in the article are tested on a practical example, which considers the procedure for optimizing the load grip lever. Such a grip has a complex nature of loading, and therefore its most rational structure is not obvious. Therefore, in order to search for a rational design of its elements, it is advisable to use conceptual topology optimization. Optimization made it possible to reduce the mass of the lever of such a grip by 42%. At the same time, the strength of the new solution increased by 15%, and the stiffness increased by 49%.

Analysis of the sources of scientific and technical literature shows that the main factors that cause the accident rate of lifting structures are factors of manmade, natural and «human» characters. The article proposes a methodology for identifying and assessing the significance of factors that are, at first glance, indirect, but have a significant impact on the causes of the accident rate of boom self-propelled cranes. The proposed methodology consists of three stages, each of which separately is quite well tested by other authors. At the first stage, based on the analysis of expert assessment according to the Hay method, it is proposed to identify significant factors. At the second stage, on the basis of the chi-squared criterion, the significance of the factor is assessed. At the third stage, a methodology for conducting a numerical experiment is proposed to assess the significance of factors based on the use of neural networks. Obviously, the proposed methodology can also be used in assessing the significance of factors of other events, and not only in case of accident rate of lifting structures.
The effect of the thermal conductivity by the materials of contact surfaces on the heat balance of the jet-grouting drill stem hydraulic elements

Published: March 2023

The paper is deals with the influence of thermal conductivity and the materials of the contact surfaces of the drill shaft and the sealing element on the change in the thermal balance of the structural unit «drilling string» used in the jet grouting technology to fix weak and unstable types of soils. A model with nodes for the computational grid of the “hydraulic puller” assembly unit is shown, part of which are the considered drill shaft and sealing elements. The temperature values are calculated by the finite element method in the «Siemens Femap’s» environment depending on the change in the thermal conductivity coefficients of the contacting elements. Calculations were carried out for the fourth part of the indicated model, due to the axisymmetry of the problem being solved, this made it possible to significantly reduce the amount and time of calculations. Graphs of the corresponding dependence are constructed for a number of points located in the characteristic areas of the hydraulic stripper. Also, by power regression, expressions were obtained that allow calculating the temperature values in the indicated areas of the considered assembly. The obtained dependencies will make it possible in the future to select the material for the drill shaft of the hydraulic puller based on the optimal ratio of the thermal conductivity of the shaft, its corrosion resistance, determined by the chemical composition of the steel and the thermal conductivity of the sealing.
