The article presents a method of assessing the stability of the information and telecommunication network in terms of informational impact. In modern war, the primary objects of directed counteraction and defeat are presented with control systems rather than troops and weapons. The predicted nature of the enemy’s impact on the military control system and the information and telecommunication network as its technical basis leads to the emergence of new requirements for the quality of the latter. The presented approach allows us to determine the order and type of impact on each element of the TCS, which in turn will allow us to assess the comprehensive indicator of the stability of the network (the coefficient of downtime or serviceable action).

Telecommunication network infrastructures both stationary and ad hoc, play an important role in maintaining the stability of society worldwide. The protection of these critical infrastructures and their supporting structures become highly challenged due to its complexity. The understanding of interdependency of these infrastructures is the essential step to protect these infrastructures from destruction and attacks. This paper presents a critical infrastructure detection model to discover the interdependency based on the theories from social networks and new telecommunication pathways while this study transforms social theory into computational constructions. The procedure and solution of protecting critical infrastructures are discussed and computational results from the proposed model are presented.

Представлены подходы к повышению устойчивости функционирования информационно-телекоммуникационной сети, которые способствуют оптимизации процесса передачи данных среди обменников информации за счет повышения быстродействия и нахождения оптимального пути передачи данных. Отмечается, что сокращение времени обмена информацией между абонентами будет происходит по наиболее короткому пути и это должно существенно повлиять на качество информации,ее важность и необходимость при ведении боевых действий в условиях радиоэлектронного противодействия противника. Various approaches to improving the stability of telecommunications networks, which lead to optimizing the data transfer process by increasing the speed and finding the most optimal data transfer path, are presented. It is noted that the reduction of the data exchange time between subscribers will occur along the shortest path, which will significantly affect the quality of information, its importance, and the need for conducting combat operations in the condition of electronic counteraction of the enemy.

The paper suggests a method of early detection of cyber-attacks by using DDoS attacks as an example) using the method of extreme filtering in a mode close real time. The process of decomposition of the total signal (additive superposition of attacking and legitimate effects) and its decomposition using the method of extreme filtering is simulated. A profile model of a stochastic network is proposed. This allows to specify the influence of the intruder on the network using probabilistic-time characteristics. Experimental evaluation of metrics characterizing the cyber-attack is given. It is demonstrated how obtained values of metrics confirm the process of attack preparation, for instance the large-scaled telecommunication network, which includes the proposed method for early detection of attacks, has a recovery time of no more than 9 s, and the parameters of quality of service remain in an acceptable range.

The criteria of the coordinate measurements quality at pilot-experimental production based on contemporary methods of quality management system and traditional methods of the measurements quality in Metrology are considered. As an additional criterion for quality of measurements, their duration is proposed. Analyzing the problem of assessing the quality of measurements, the authors pay particular attention to the role of technological heredity in the analysis of the sources of uncertainty of coordinate measurements, including not only the process of manufacturing the part, but all stages of the development of design and technological documentation. Along with such criteria as the degree of confidence in the results of measurements; the accuracy, convergence, reproducibility and speed of the results must take into account the correctness of technical specification, and such characteristics of the shape of the geometric elements to be controlled, such as flatness, roundness, cylindrical. It is noted that one of the main methods to reduce the uncertainty of coordinate measurements is to reduce the uncertainty in the initial data and measurement conditions, as well as to increase the stability of the tasks due to the reasonable choice of the basic geometric elements (measuring bases) of the part. A prerequisite for obtaining reliable quality indicators is a quantitative assessment of the conditions and organization of the measurement process. To plan and normalize the time of measurements, the authors propose to use analytical formulas, on the basis of which it is possible to perform quantitative analysis and optimization of quality indicators, including the speed of measurements.

The article presents scientific research in the field of statistical controllability of the food production process using the example of bakery products for a certain time interval using statistical methods of quality management. During quality control of finished products, defects in bakery products were identified, while the initial data were recorded in the developed form of a checklist for registering defects. It has been established that the most common defect is packaging leakage. For the subsequent statistical assessment of the stability of the production process and further analysis of the causes of the identified defect, a Shewhart control chart (p-card by an alternative feature) was used, which allows you to control the quality of manufactured products by the number of defects detected. Analyzing the control chart, it was concluded that studied process is conditionally stable, and the emerging defects are random. At the last stage of the research, the Ishikawa causal diagram was used, developed using the 6M mnemonic technique, in order to identify the most significant causes that affect the occurrence of the considered defect in bakery products. A more detailed study will allow the enterprise to produce food products that meet the established requirements.

AbstractTo which extent do happiness correlates contribute to the stability of life satisfaction? Which method is appropriate to provide a conclusive answer to this question? Based on life satisfaction data of the German SOEP, we show that by Negative Binomial quasi-maximum likelihood estimation statements can be made as to how far correlates of happiness contribute to the stabilisation of life satisfaction. The results show that happiness correlates which are generally associated with a positive change in life satisfaction, also stabilise life satisfaction and destabilise dissatisfaction with life. In such as they lower the probability of leaving positive states of life satisfaction and increase the probability of leaving dissatisfied states. This in particular applies to regular exercise, volunteering and living in a marriage. We further conclude that both patterns in response behaviour and the quality of the measurement instrument, the life satisfaction scale, have a significant effect on the variation and stability of reported life satisfaction.

The concept of transporting medical products by drone is gaining a lot of interest amongst the medical and logistics communities. Such innovation has generated several questions, a key one being the potential effects of flight on the stability of medical products. The aims of this study were to quantify the vibration present within drone flight, study its effect on the quality of the medical insulin through live flight trials, and compare the effects of vibration from drone flight with traditional road transport. Three trials took place in which insulin ampoules and mock blood stocks were transported to site and flown using industry standard packaging by a fixed-wing or a multi-copter drone. Triaxial vibration measurements were acquired, both in-flight and during road transit, from which overall levels and frequency spectra were derived. British Pharmacopeia quality tests were undertaken in which the UV spectra of the flown insulin samples were compared to controls of known turbidity. In-flight vibration levels in both the drone types exceeded road induced levels by up to a factor of three, and predominant vibration occurred at significantly higher frequencies. Flown samples gave clear insulin solutions that met the British Pharmacopoeia specification, and no aggregation of insulin was detected.

Abstract Introduction A number of organizations publish comparisons of civilian health systems between countries. However, the authors were unable to find a global, systematic, and contemporary analysis of military healthcare systems. Although many databases exist for comparing national healthcare systems, the only such compilation of information for military medical systems is the Military Medical Almanac. A thorough review of the Almanac was conducted to understand the quality of information provided in each country’s profile and to develop a framework for comparing between countries. This information is valuable because it can facilitate collaboration and lesson sharing between nations while providing a structured source of information about a nation’s military medical capabilities for internal use. Materials and Methods Each of the 142 profiles (submitted by 132 countries) published in the Almanac were reviewed. The information provided was extracted and aggregated into a spreadsheet that covered the broader categories of country background, force demographics, beneficiary populations, administration and oversight, physical structures and capabilities, research capabilities, and culture and artifacts. An initial sample of 20 countries was evaluated to test these categories and their subsections before the rest of the submissions were reviewed. Clear definitions were revised and established for each of the 69 subcategories. Qualitative and quantitative data were compiled in the spreadsheet to enable comparisons between entries. Results Significant variation was found in how information was presented in country profiles and to what extent this was comparable between submissions. The most consistently provided information was in the country background, where the categories ranged from 90.15% to 100% completion across submissions. There was inconsistency in reporting of the numbers and types of healthcare workers employed within military medical services. Nearly 25% of nations reported providing medical care to family members of service members, but retirees, veterans, reservists, and law enforcement personnel were also mentioned. Some countries described organizational structures, military medical education institutions, and humanitarian operations. A few reported military medical research capabilities, though each research domain was present in 25% or less of all submissions. Interestingly, cultural identities such as emblems were present in nearly 90% of profiles, with many countries also having badges, symbols, and mottos. Conclusions The Military Medical Almanac is potentially a highly valuable collection of publicly available baseline information on military medical services across the world. However, the quality of this collection is highly dependent on the submission provided by each country. It is recommended that the template for collecting information on each health system be refined, alongside an effort to increase awareness of the value of the Almanac as an opportunity to raise the international profile of each country’s military medical system. This will ensure that the Almanac can better serve the international military medical community.

This paper addresses the fundamental role that cultural heritage can play in local development processes to guarantee community wellbeing, quality of life, and quality of society. The enhancement of cultural heritage’s tangible and intangible values may result in sustainable and resilient territory, but a number of issues emerge when dealing with the reuse of specific inherited assets, such as former military barracks. This paper conducts an in-depth analysis of these assets, especially those released from the military after the end of the Cold War. We thus explore the Italian case through the comparison of before-1900 and 1900-to-1950 former military barracks. The objectives are the following. First, to discover how these two types of military sites are approached (or no) as proper heritage. Second, to understand how the reuse management is carrying out and how it deals with conservative and profit-driven approaches towards the achievement of cultural, economic, environmental, and social sustainability. Third, to compare the Italian case with similar international good practices to discover common/different trends and innovative solutions to be applied in Italy.
