Context. The constant growth in the volume of information, the increase in the speed of information flows in digital communication networks, as before, makes the task of assessing the service stability for traffic flows an urgent one. A simple solution to ensure high service stability is to build a network of sufficient capacity for any traffic that will be thrown at it. To solve the problems of analyzing telecommunication systems, it is necessary to have appropriate models and engineering methods that allow to assess the service stability and predict the characteristics of their operation based on measurement data. In these conditions, the development of new methods for analyzing the traffic of multiservice networks that provide simplicity of calculations and their acceptable accuracy becomes especially relevant.
Objective. The purpose of this paper is to study the traffic and service stability for users.
Method. We propose a hybrid method for detecting anomalies in multiservice network traffic that uses algorithms without identification, adaptation and Mamdani fuzzy inference. The peculiarity of multiservice traffic as an object for assessing the existence of anomalies is the presence of stochastic processes in it subject to different distribution laws. For the experimental evaluation of the proposed method and algorithms, we have chosen the Poisson and Pareto distribution laws that define the limiting cases of traffic regularity. The method allows for monitoring and managing faults in a multiservice network in order to determine the causes of their occurrence. The following requirements are imposed on the developed algorithms for detecting anomalies in the traffic on multiservice networks: functioning in real or near real time; maintaining a given service stability; simplicity of implementation. The algorithms belong to the class of adaptive hybrid algorithms for identifying traffic parameters. They are used for both stationary and nonstationary traffic. Traffic is modeled as stochastic processes. Each belongs to the corresponding class, which is determined by the law of distribution of stochastic processes.
Results. Experimental evaluation of the proposed method and algorithms has shown that they allow us to estimate the trends of these stochastic processes in real time, with high accuracy and while maintaining the service stability.
Conclusions. The application of the developed method of troubleshooting management in a multiservice environment helps to improve the service stability by timely detecting problems, reducing the time of their elimination and reducing downtime, which, in turn, affects the increase in service reliability.
STABILIZATION OF DISCRETE-TIME SYSTEMS WITH STATE-DELAYS AND SATURATING CONTROL INPUTS
Authors: Dorofieiev Yu. I. , Lyubchyk L. M. , Melnikov O. S. 
Published: July 2023

Context. The presence of time delays occurs in many complex dynamical systems, particularly in the areas of modern communication and information technologies, such as the problem of stabilizing networked control systems and high-speed communication networks. In many cases, time-delays lead to a decrease in the efficiency of such systems and even to the loss of stability. In the last decade, many interesting solutions using the Lyapunov-Krasovskii functional have been proposed for stability analysis and synthesis of a stabilizing regulator for discrete-time dynamic systems with unknown but bounded state-delays. The presence of nonlinear constraints on the amplitude of controls such as saturation further complicates this problem and requires the development of new approaches and methods.
Objective. The purpose of this study is to develop a procedure for calculating the control gain matrix of state feedback that ensures the asymptotic stability of the analyzed system, as well as a procedure for calculating the maximum permissible value of the state-delay under which the stability of the closed-loop system can be ensured for a given set of admissible initial conditions.
Method. The paper uses the method of descriptor transformation of the model of a closed-loop system and extends the invariant ellipsoids method to systems with unknown but bounded state-delays. The application of the Lyapunov-Krasovskii functional and the technique of linear matrix inequalities made it possible to reduce the problem of calculating the control gain matrix to the problem of semi-definite programming, which can be solved numerically. An iterative algorithm for solving the bilinear matrix inequality is proposed for calculating the maximum permissible value of the time-delay.
Results. The results of numerical modeling confirm the effectiveness of the proposed approach in the problems of stabilizing discrete-time systems under the conditions of state-delays and nonlinear constraints on controls, which allows to recommend the proposed method for practical use for the problem of stability analysis and synthesis of stabilizing regulator, as well as for calculating the maximum permissible value of time-delay.
Conclusions. An approach is proposed that allows extending the invariant ellipsoids method to discrete-time dynamic systems with unknown but bounded state-delays for solving the problem of system stabilization using static state feedback based on the application of the Lyapunov-Krasovskii functional. The results of numerical modeling confirm the effectiveness of the proposed approach in the presence of the saturation type nonlinear constraints on the control signals.

Context. The article proposes a method of analyzing the proposals of team members in order to avoid conflict situations at the stage of team formation.
Objective. The object of the study is the method of analyzing the proposals of team members while solving project tasks.
The purpose of the work is to analyze the developed method of analysis of proposals of team members to avoid or resolve conflict situations at the stage of team activation
Method. The developed method is based on the theory of matrix games. Conflicts between individual team members mainly arise at the stage of team formation. For the project manager, it is important to identify the conflict situation in time and find a way out of it to satisfy both team members and without harming the teamwork as a whole. A team created to implement an IT project is often faced with a situation where two of its members have different visions of approaches to creating the final product. At the same time, each of them has experience in the development of similar software products or services by different teams. To effectively solve this situation, we suggest using approaches typical of bimatrix games, when each of these team members is considered as a player. This takes into account the fact that the bimatrix theory of games is based on a conflict between two players whose interests are opposite – an antagonistic zero-sum game is precisely the basis of the developed approach.
Results. The proposed method of analysis of proposals of team members contributes to the avoidance or resolution of conflict situations at the stage of their closer interaction. For efficient solution of the said situation, we propose to use approaches being typical for bimatrix games when each of these team members is treated as a player. At the same time, account is taken of the fact that the bimatrix game theory is based on a conflict of two players whose interests are opposite – an antagonistic game with a zero sum being that very element to constitute the basis of the approach developed.
Conclusions. The given calculation of the model example shows that the use of the proposed method allows the project manager to give a reasonable preference to another team member, since the expected average profit of this player is greater than that of the first player. In this case, the manager has an opportunity to simulate situations for the players (for the team) and promptly respond to probable deviations of their behavioral strategies from the optimal ones, establish healthy relationships between team members and choose the best proposals for solving project tasks.

This approach is the systemological basis of studied object entropy model creation and algorithmization by ecological functional of quality of the complex system objects goal state. The quality functional is the interrelation of «object systems-environment» state entropy functions and their interaction processes, which are gotten through monitoring data statistical analyses of objects that belong to technogenic (economical), social and natural systems.
Results. The usage of systemology basis complex union for studied object structure identification is suggested for the first time, along with identification of theoretical knowledge for informational entropy for any object system element description and entropic description of states and process. The relative accordance functional is introduced for final evaluation of the studied object equilibrium. It allows to estimate the presence of system and processes unstable points on the basis of nested system structure. It is important for decision making with synergistically positive feedbacks prediction.
Conclusions. The systems and process states entropic estimation complex approach is determined. The systemological model «object-environment» is the basis for determining conditions of studied object sustainable development due to usage of found spontaneous and natural synergistically feedbacks. The universal research base for complex systems study was received for their state and functionality estimation due to process synergy and «object-environment» connections that are based on complex usage of systemological modelling and input information entropy estimation.

The aim of the article is to present the scale and characteristics of the phenomenon of church marriages by Poles who migrated to England and Wales. The phenomenon of heterogamous relationships has grown over the last several decades due to factors such as the expansion of the community of European Union member states, globalization processes, and the resulting diversity of the population of migrants. The article is focused mainly on religious mixed marriages. The empirical material consisted of data from the records of the largest organization of the Polish community in Britain. The authors analysed the data of 25,530 marriages of Poles living in England and Wales, registered between 2007 and 2020, including 2,922 mixed religions marriages.
Spiritual Theology: The Contribution of Edith Stein
Authors: Zyzak Wojciech 
Published: July 2023

The author of the article studies the spirituality of Edith Stein. He presents Edith Stein’s contribution to the methodology of spiritual theology, her anthropological and theological vision, her evolution of the religious experience, the life of prayer and call to mysticism. Edith Stein carried out research which today would be regarded as being interdisciplinary. Her reflections have a huge influence on the methodology of the theology of spirituality. The spirituality of the Cross which Stein writes about in compliance with the classic masters, nowadays may be an adjustment to the incarnational spirituality, in her overly optimistic view on the usage of creatures and taking for granted the spiritual value of suffering.
Experimental investigations on early crack development in fully restrained reinforced concrete members with active zero-displacement control
Authors: Schmidt Christopher , Chudoba Rostislav , Jin Chao , Hegger Josef 
Published: July 2023

AbstractThe development of restraint-induced stress in reinforced concrete members at an early age can be tested using setups applying either passive or active displacement control. To provide results relevant for the practical design of minimum reinforcement to limit the crack width, an actively controlled test setup for large specimens was developed to perform a systematic experimental campaign focusing on the early crack development under well-defined mechanical and thermal boundary conditions. The full degree of restraint achieved by actively preventing any displacement of the member allowed for the theoretical interpretation of early restraint-induced stress evolution, deformation behaviour in the cracked and uncracked regions, and reinforcement stress for a variety of parameters, including hydration rates, member height, bar diameters and subsequently reinforcement ratio. The cracking process, starting with primary cracks accompanied by secondary cracks within the effective reinforcement area, is monitored in combination with the development of the tensile strength and Young’s modulus of the concrete. Furthermore, the time of cracking and the forces released upon crack occurrence, considering the effect of self-equilibrating stresses, are determined, analysed, and compared with the results of crack-force based design rules to determine the minimum amount of reinforcement that ensures the crack width limitation.

Published: July 2023

IntroductionThe cochlear implant (CI) procedure in patients with inner ear malformations is challenging. The aim of this study was to evaluate auditory perception and speech development in children with enlarged vestibular aqueduct (EVA) and to relate the results to the diagnosis of Pendred syndrome (PS), imaging findings, surgical course, and postoperative period.Material and methodsThe study group consisted of 49 children with EVA, aged 11 months to 15 years, with severe to profound hearing loss. The EVA patients included 22 with PS and 27 with nonsyndromic EVA (NSEVA). The control group consisted of 46 children with nonsyndromic deafness. Outcomes after cochlear implantation were evaluated annually for at least 10 years. Auditory performance was assessed by categories of auditory performance (CAP) and Meaningful Auditory Integration Scale (MAIS). Speech outcomes were evaluated by Speech Intelligibility Rating Scale (SIR) and Meaning Use of Speech Scale (MUSS). Genetic counselling, imaging studies, and vestibular testing were also evaluated when available.ResultsAll patients included in the study benefited from cochlear implants, especially when implantation was performed before the age of 3 years. After CI, EVA patients (PS and NSEVA) achieved a steeper rate of increase in auditory perception and speech intelligibility, demonstrating higher scores at each follow-up point compared to nonsyndromic patients (NS). There were no differences in auditory and speech perception between NSEVA and PS patients. In addition to EVA, the most commonly diagnosed malformation was incomplete partition type 2 (IP-2), the presence of which negatively affected postoperative outcomes. During cochleostomy, cerebrospinal fluid (CSF)/perilymph leakage was observed in 50% of implanted ears, but its presence did not affect the final outcomes.ConclusionsEarly cochlear implantation is associated with satisfactory speech and auditory development in children with EVA. Due to the presence of inner ear malformations in patients with Pendred syndrome, detailed imaging of the temporal bone is indicated. Despite the frequent occurrence of CSF/perilymph leakage during cochleostomy, patients with EVA benefit satisfactorily from cochlear implantation.

: Type 2 Diabetes mellitus (DM) is a chronic metabolic disorder. India has 72.9 million people living with diabetes (8.8%). The Cardio Vascular Disease (CVD) risk increases in patients with Type 2 diabetes. The Non-HDL-C level includes cholesterol carried in several atherogenic lipoproteins. The estimation of non-HDL-C may provide a better means to follow these patients toward their treatment goals. The study compares the level of non-HDL-C in non diabetic, pre-diabetic and diabetes patients and their occurrence of dyslipidemia. : The study group included 1418 patients and were grouped as – Non diabetic, pre-diabetic and Diabetic, having age group of 20 to 85 years. The Male:Female ratio was 1.9:1. Their blood samples were analysed in Clinical Biochemistry Laboratory on automated chemistry analyzer with quality checks.: The Non Diabetic group (HbA1c&#60;5.7%) had 564 patients having Non-HDL-C 127.85±1.79 mg/dl; the Pre-Diabetic group (HbA1c-5.7-6.4%) had 316 patients with Non-HDL-C 132.37±2.35 mg/dl and Diabetic group (HbA1c &#62;6.4%) had 538 patients and its non HDL-C was 148±4.27 mg/dl. : This study showed the groups, pre-diabetic and diabetic, had Non-HDL-C &#62;130mg/dl. An increase in Non-HDL-C levels is associated with increased risk of CVD according to Adult Treatment Panel (ATP) III guidelines.

HbA1c is one of the important laboratory markers of blood glucose levels monitoring over last 2-3 months. Studies have shown that many factors affect HbA1c levels, hence it is not the only investigation to diagnose diabetes mellitus. As both iron deficiency anaemia and diabetes mellitus are highly prevalent disorders, effect of iron deficiency anaemia on HbA1C need to be evaluated. Many factors such as haemolytic anaemia, vitamin deficiencies, pregnancy. Kidney disease, haemoglobin variants can affect HbA1C levels. This study had two groups of participants. Group 1 included diabetic patients with iron deficiency anaemia and group 2 included diabetic patients without iron deficiency anaemia. Significant correlation between HbA1C and iron deficiency anaemia has been found. PCV, MCH, MCHC, MCV are low in diabetics with Iron deficiency anaemia and high in diabetics without iron deficiency anaemia. Need for anaemia screening before treatment planning of diabetes based on HBA1C levels must be considered and for optimal diabetes control, treating anemia is necessary.

Serum AFP as a poor clinical performance values especially when it comes to deal with the early and AFP-negative diagnostic of HCC. The aim of this work was to assess the contribution of AFP in the diagnosis of HCC. : A total of 95 subjects was enrolled a prospective observational study by consecutive enrolment and divided in two groups. The first group was made up with subjects in whom the diagnosis of HCC had been retained while the second was the control group which was free of HCC. AFP levels were performed by electrochemiluminescence immunoassay on the cobas e411. Data were captured in Excel and analyzed by Ri386 version 4.1.2 binary for macOS 10.13. The Log of median of AFP in HCC subjects was significantly greater than in non HCC subjects 6.91 ng/mL versus 1.43 ng/mL, Wilcoxon &#60; 0.001. At the cut-off of 200 ng/mL, the clinical performances showed an acceptable sensitivity 97.1% CI 95% [93.7 – 100] but a poor specificity 73,8% CI 95% [64.9 – 82.6] and out of the 34 cases of HCC, one case (2.9%) was AFP-negative HCC. our data show an acceptable sensitivity but a weak specificity of AFP as a biomarker for HCC at cut-off 200 ng/mL. This suggests that AFP should be used with other biomarkers mainly for the early and AFP-negative HCC diagnosis.
filosofía como cuidado de sí y cuidado del otro
Authors: Schutijser Dennis 
Published: July 2023

El presente artículo presenta los temas comunes con respecto a la filosofía como cuidado. La primera distinción es entre el cuidado de uno mismo y el cuidado del otro. Dentro del marco de la filosofía como cuidado de uno mismo, la siguiente distinción es entre un enfoque en diferentes formas de felicidad, por un lado; y un enfoque en la cuestión del significado en el otro. Dentro del marco de la filosofía como cuidado por el otro, otra distinción es entre el cuidado por el otro basado en una vulnerabilidad compartida y el requisito concomitante de atender al otro en el cuidado de sí mismo; y sobre una fragilidad personal frente al otro y la apelación a nuestra responsabilidad de cuidar al otro.
El objetivo del artículo, más allá de presentar una breve presentación de los debates actuales más importantes sobre la filosofía como cuidado, es mostrar que, en muchos sentidos, tal concepto de cuidado desde el punto de vista de la filosofía superará las expectativas y presentará la filosofía como una práctica que más bien perturba, problematiza y subvierte la práctica común de cuidado, en lugar de reforzarla.
