Prediction of special cases in flight is the main task of parametric diagnostics of aircraft technological equipment. To solve this problem, on-board means of automated control, diagnostics and control of on-board equipment, unloading and information support of the crew use mathematical models based on the trend analysis of some registered operating time parameters. However, existing diagnostic models based on the corresponding mathematical models do not always allow predicting the occurrence of process equipment failures. What makes the task of forecasting special cases in flight relevant. The paper proposes a method for predicting special cases in flight based on identifying abnormal sequences in the diagnostic data of aircraft technological equipment. To identify abnormal sequences, it is proposed to use a hybrid stochastic model based on a combination of Markov and production models using temporal rules to specify transition probabilities between process states. By including more precise production rules in the model, the probability of describing random processes that are not Markovian is increased, and it becomes possible to integrate a priori expert knowledge into the model, which is very important for predicting special cases in flight. The application of the proposed method will allow to implement the prognostic principle of flight safety management, as well as to obtain the economic effect of preventing aircraft downtime due to sudden equipment failure.

The article proved that the vast majority of the population of developed countries own digital technologies and effectively use them in various fields, including education and science. The challenges and threats of the Сovid-19 pandemic, which began in 2019 and applies to all countries of the world, have changed approaches to the learning process, translating it into a virtual plane, giving a significant impetus to models and methods of distance learning, changing teaching methods and practices, transforming didactic materials and putting forward requirements for the planning of the educational process. The main trend in informatization of education is the development of innovative educational processes based on the use of information and communication technologies of distance learning, and distance learning forms of support for traditional learning based on Internet technologies. The training of air traffic controllers is quite complicated and requires constant monitoring of knowledge and skills, maintaining practical habits and training, and effective planning of class schedules. Air traffic controllers are an important component of air traffic safety, and civil aviation safety depends on their training. The transformation of the education system requires new approaches to building training systems and knowledge assessment systems for air traffic controllers. It is necessary to introduce information technologies in the activities of educational institutions that can automate the training processes, provide teachers and the educational department with tools for the intellectual planning of the educational process, provide automated assessment of knowledge, skills and habits for their further consideration in the organization of the educational process. The article developed the structure and basic methods of an information-analytical system for assessing the knowledge of air traffic control dispatchers to take into account the results obtained in the planning of the educational process. The structure of the system meets the principles of systemicity. The prospects of these studies are the integration of the developed system into the decision support system for organizing and planning the educational process at the Flight Academy to improve the quality of training of air traffic control dispatchers.

Published: July 2021

Problems of securing noise immunity and information transmission concealment in telecommunication networks of information systems are considered. In order to improve performance, it is proposed to use scrambling coding sequences, which spread the spectrum of the bits being transmitted. To synthesize new scrambling coding sequences, tenth degree primitive polynomial is used. Autocorrelation properties of the obtained scrambling coding sequence are studied. Limitations caused by those properties are deduced. In order to establish a possibility of synthesized scrambling coding sequence use in the telecommunication networks data transmission channels, it is carried out computer simulation of the transmission process of the bit set, whose spectrum is spread by the obtained sequence. In the process of computer simulation, a mixture of the desired signal in the form of a scrambled bit set, internal noise of information transmission channel and interfering signal was formed. While the powers of the internal noise and interfering signal remained constant, power of the bit sequence gradually assumed three discrete values. As a result of the research, it is established that utilization of the synthesized scrambling sequence permits to perform extraction of the bits being transmitted, under conditions in which the power of the noise interfering signal and the internal noise of the channel surpasses power of the desired channel by up to 18 decibel. The limitations set by the use of the synthesized coding sequence are described. An inference concerning a possibility of obtained coding sequence use in practical implementation of telecommunication channels of information networks is made.
Practical aspects of noise immune data transmission channel design in telecommunication networks

Published: July 2021

Practical aspects of noise immune data transmission channel design in telecommunication networks are considered. Main accent is made on securing noise immunity and concealment of information transmission, as well as on countering its interception by the rogue elements. It is noted that satisfaction of the mentioned requirements is possible by using spectrum spreading of useful signal bits and deploying data scrambling. Design of telecommunication channel with spectrum spreading and scrambling on the base of pseudo noise coding sequences derived from primitive polynomials of the eighth and fifteenth order that possess good auto and inter correlation properties are proposed. While studying practical aspects of the telecommunication channel design, its structure is put forward that consists of frames counting 256 bits, each of which is spread by using the synthesized pseudo noise sequence. In this case, the second synthesized pseudo noise coding sequence with the length of 32768 chips is used to mark the frame duration and perform additional information scrambling. Computer simulation is employed to study performance of the designed algorithm. Simulation results proved that processing of the additive mixture of the useful signal and interferences, which surpass useful signal two times in their power, by the matched despreading filters permits to confidently determine the frame structure of the information being transmitted by finding frame beginning pulses and determining values of the useful information bits. Analysis of the results obtained during the research permits to assume that designed telecommunication channel can be successfully used while developing noise immune concealed telecommunication networks. It is proposed to carry out further research to study boundary possibilities of the designed telecommunication channel in terms of useful signal to interference ratio.

With the advent of 5G, the market has been expecting the immersive user experience with rich multimedia content. Meeting such requirements within the physical constraints of limited spectrum and infrastructure availability is a challenging task, which prevents operators to scale their services properly. Currently, mobile operators are forced to invest large amount of money in their infrastructure, in order to maximize the capacity by network densification and higher frequency reuse factors. The dark side of such trend is that infrastructure becomes more expensive, spectrum price is getting higher and total cost of ownership for operator increases drastically. Nowadays, with the rise of artificial intelligence, cloud and edge computing the network becomes more flexible that opens many opportunities to enhance the performance and user experience. In this paper, we propose a new approach for content management in mobile network by using predictive caching of rich multimedia content in edge servers. Proposed approach is based on the content popularity prediction by using recurrent neural networks, that allows to deliver corresponding content in the close proximity to the target end users by the time it will be needed. Simulation results show that the proposed model is more than 90% accurate for both daily and weekly timeframes. Furthermore, we develop a method of personalized content caching in user devices based on their subscriptions and preferences, to make sure that user will have the best experience. Proposed approach for content management allows to improve the overall network performance by proactive content caching during the time of low network load. Moreover, the proactive caching allows to download the content in the best quality, regardless of the network congestions and bottlenecks.
Optimization of information exchange in networks under conditions of uncertainty
Authors:   State University of Telecommunications, Senkov O. V.
Published: July 2021

The article considers the problem of optimizing the exchange of information in the conditions of uncertainty that arises in the process of functioning of converged networks. The uncertainties formulated in the paper are characterized by discrepancies in the "interests" of different network nodes, varying degrees of awareness or incomplete data on the value of system parameters. Such uncertainties lead to a decentralized process management strategy in a converged network. The problem of interaction of network nodes is considered from the point of view of game theory, at the same time players act as separate nodes of system, the exchange of information between which is limited by conditions of uncertainty. Decision-making procedures are formulated for the following cases: when one node is the center and the other opposes it and the center knows information about the choice of the second player; when the center does not know the capabilities of the second player, and the uncertainty lies in the random nature of the strategy of the second player; network node synergy model. For the first case, the optimal control is based on the maximum action of the first station (center) and the maximum resistance of the other station (second player) and can use the maximum model. For the second case, the limitations of the strategy of the game (including the strategy of punishment of the player) are determined and it is proved that the gain, more than the maximum guaranteed result of the center, cannot be obtained on any other class of strategies. The relation of the center to the uncertainty in the model based on the synergetic concept of the operation of convergent networks is such that it seeks to maximize the linear convolution of the values of its criterion. The peculiarities of constructing a strategy for the exchange of information between individual nodes of the network in the presence and absence of isolated points in the set of choices of the player who opposes the center are studied. The developed model of interaction of heterogeneous subsystems of the telecommunication network in the conditions of uncertainty can be used for situations when nodes have incomplete information about both the system as whole and other nodes.

Мета статті — з’ясувати особливості навчання студентів професійної майстерності в закладах вищої освіти мистецького профілю в умовах реформування, що безпосередньо впливає на майбутнє мистецької освіти в Україні. Методологію дослідження визначають загальнонаукові теоретичні методи аналізу, синтезу й абстрагування, що дало змогу вивчити специфіку навчання студентів професійної майстерності в мистецьких закладах вищої освіти та здійснити переосмислення їхньої ролі й місця і в освітній системі, і в суспільстві загалом. Наукова новизна дослідження визначається осмисленням теоретичних і практичних особливостей навчання студентів професійної майстерності в мистецьких закладах вищої освіти, що пов’язано із затвердженням стандартів вищої освіти із культурно-мистецьких спеціальностей та відповідності міжнародним стандартам із збереженням фундаментальних мистецьких вітчизняних традицій. Висновки. Встановлено, що під час навчання студентів професійної майстерності в закладах вищої освіти мистецького профілю необхідно враховувати соціальні зміни, науковий прогрес, їхню роль і місце в освітній системі чи навпаки — деструктивні перетворення в суспільстві та його інституціях, які також впливають на формування свідомості й підсвідомості студента й викладача. Виявлено, що у фаховій підготовці студентів у мистецьких закладах вищої освіти ключове місце відводиться педагогічним нововведенням у культурно-мистецьких освітніх процесах (самоосвітній, дослідницький, управлінський, психологічний тощо). Сутність цих процесів полягає передусім у зміні ставлення студента до процесу навчання та осмисленні свого місця в мистецькій галузі. Важливе значення для професійної підготовки студентів має самостійна робота, що як специфічна форма освітньої діяльності потребує самовдосконалення, розширення світогляду, поглиблення знань, планування та ін., оскільки саме зацікавлення студентом певною спеціальністю спрямовує його на оволодіння професійною майстерністю.

Мета статті — окреслити основні аспекти культурно-дозвіллєвого та рекреаційного потенціалу сучасних готельно-ресторанних комплексів в Україні. Методологія дослідження ґрунтується на інклюзивному поєднанні методологічного інструментарію культурологічного, мистецтвознавчого, соціокультурного та структурно-функціонального підходів, а також підходів, інтегрованих із менеджменту. Активно використані загальнонаукові методи пізнання (аналізу, синтезу, спостереження) і принципи (достовірності, системності). Наукова новизна полягає в тому, що в статті розширено уявлення про культурно-дозвіллєвий і рекреаційний потенціал готельно-ресторанних комплексів в сучасній Україні, зокрема на прикладі заміського комплексу «ШишкіNN». Висновки. Конкуренція, значні зміни у вимогах до якості життя, дедалі зростаючі потреби та широкий спектр інтересів людей вимагають від готельно-ресторанних комплексів здатності переорієнтовуватися на надання низки додаткових послуг. Одними з найважливіших складових, яким повинен відповідати сучасний готельно-ресторанний комплекс, є культурно-дозвіллєва і рекреаційна. Для реалізації культурно-дозвіллєвого і рекреаційного потенціалу сучасний готельно-ресторанний комплекс повинен передусім враховувати такі аспекти: особливості архітектурного стилю і забудови; рекреаційне зонування і організацію простору відпочинку; розташування в екологічно привабливому місці; художньо-естетичне вирішення та якісне декоративне оздоблення інтер’єру; проведення різних культурно-дозвіллєвих заходів; спеціальну підготовку керівного і обслуговуючого персоналу тощо. Звернено увагу, що у сучасній Україні при архітектурно-дизайнерському проєктуванні готельно-ресторанних комплексів дотримуються традицій спеціального оформлення та сервісу для максимального забезпечення культурно-дозвіллєвих та рекреаційних потреб відпочиваючих. Про це свідчить діяльність таких заміських комплексів, як «Чабани», «Два Бобри», «Козацький Стан», «ШишкіNN».

Мета статті — проаналізувати формування та розвиток гастрономічного туризму в контексті соціокультурного вектора розуміння сутності туристичної діяльності. Методологія дослідження ґрунтується на застосуванні системно-структурного підходу, орієнтованого на вивчення туризму як цілісного соціокультурного явища. Наукова новизна полягає в тому, що вперше сутність гастрономічного туризму розглянуто в соціокультурному аспекті, що дає підстави визначити його як значущий реагент впливу на соціальні процеси. Висновки. Гастрономічний туризм доволі молодий напрям, який активно розвивається, але вже сьогодні туристи віддають перевагу пізнанню традицій і звичаїв іншої країни шляхом дегустації національних страв і напоїв. Відтак, враховуючи, що гастрономічна традиція — це процес, що постійно розвивається, завдання для професіоналів полягає в залученні інновацій, оновленні й адаптації своїх пропозицій до потреб нової споживчої культури. Тенденції розвитку гастрономічного туризму у світі дають підстави вважати його стійким трендом, який уможливлює взаємодію мандрівників із місцевими громадами. В умовах зростання конкуренції за увагу користувача і появи нових технологій бізнес-суб’єктам необхідно оперативно формувати оновлені стратегії просування. Визначено, що Україна має потенціал для підвищення міжнародної конкурентоспроможності туристичної галузі, зокрема завдяки посиленню мультикультуралізму туристичних потоків, зростанню попиту на нові туристичні дестинації, різноманітності культурного і природного ландшафту. Звернено увагу на потребу з’ясування чітких векторів розвитку гастрономічного туризму в країні, розробки відповідної державної підтримки туристичних дестинацій, туристичних фірм та інших стейкхолдерів, а також дослідження соціокультурних якостей туризму в контексті соціальних міграцій і діалектичної взаємодії загальносвітових процесів глобалізації та регіоналізації.

Shifting focus to online learning during the COVID-19 pandemic in Saudi Universities: Challenges and opportunities
Authors: Aljohani Nouf
Published: July 2021

Since 2020, Saudi administrations have provisionally closed educational institutions to mitigate the spread of COVID-19. At the time, employing technology was imperative to accelerate learning efforts and offer methods of enhancing interactions between learners and among learners and tutors. In this review, I first describe the e-learning systems that were used in higher education before the pandemic. Then, I investigate the impact of COVID-19 on Saudi higher education and how universities and public educational institutions responded to the pandemic. In the conclusion, I argue that policymakers, university sectors, and syllabi developers should unify national e-learning strategies, integrate technology in a systematic way, and design e-learning curricula to meet the needs of an ever-advancing world and revolutionise the learning process.
Association of increased C-Reactive Protein and hypocomplementemia with risk factors for thrombosis in women who have susceptibility for poor gestational outcome; importance of preconceptional counseling
Authors: Beksac Mehmet Sinan , Donmez Hanife Guler
Published: July 2021

This study aimed to investigate the association of increased C-Reactive Protein (CRP) and hypocomplementemia with risk factors for thrombosis such as Factor V Leiden (FVLP) and Prothrombin G20210A polymorphisms (PP), increased Activated Protein C Resistance (APCR) and decreased anti-thrombin III (ATIII) activity in women who have metabolic (MTHFR polymorphisms) and immunological risk factors (autoimmune antibody positivity, autoimmune disorders, and chronic inflammatory diseases). All patients (n= 197) were evaluated in terms of risk factors for thrombosis including FVLP, PP, increased APCR, and decreased ATIII activity as well as CRP and complement (C) 3 and C4 levels within a framework of preconceptional care program. Patients with high CRP levels together with hypocomplementemia were included to the study group (n= 13), while women with normal levels of CRP, C3, and C4 were accepted as controls (n= 184). Decreased ATIII activity was found to be statistically more frequent in the study group compared to controls (p= 0.036). There were no significant differences between the study and control groups in terms of the presence of FVLP, PP and increased APCR (p= 0.386, p= 0.462, p= 0.625, respectively). Decreased ATIII activity should be the concern of preconceptional and antenatal care programs in risky patients with increased CRP levels and hypocomplementemia in order to prevent placental inflammation related gestational complications.
Multimodal emotion recognition with hierarchical memory networks
Authors: Lai Helang , Wu Keke , Li Lingli
Published: July 2021

Emotion recognition in conversations is crucial as there is an urgent need to improve the overall experience of human-computer interactions. A promising improvement in this field is to develop a model that can effectively extract adequate contexts of a test utterance. We introduce a novel model, termed hierarchical memory networks (HMN), to address the issues of recognizing utterance level emotions. HMN divides the contexts into different aspects and employs different step lengths to represent the weights of these aspects. To model the self dependencies, HMN takes independent local memory networks to model these aspects. Further, to capture the interpersonal dependencies, HMN employs global memory networks to integrate the local outputs into global storages. Such storages can generate contextual summaries and help to find the emotional dependent utterance that is most relevant to the test utterance. With an attention-based multi-hops scheme, these storages are then merged with the test utterance using an addition operation in the iterations. Experiments on the IEMOCAP dataset show our model outperforms the compared methods with accuracy improvement.
Quantitative predicting propagation breadth and depth of microblog users’ forwarding behavior
Authors: Wang Yanben , Bai Jurong
Published: July 2021

In the microblog network, users’ forwarding behavior is widespread and the propagation range is difficult to predict quantitatively. To solve this problem, machine learning algorithms are used to quantitatively predict propagation breadth and depth of microblog users’ forwarding behavior. The dataset is preprocessed, and the extracted features are divided into three types: user features, microblog features and social features. Then the dataset is analyzed in detail; machine learning algorithms are used to predict the propagation breadth and depth of users’ forwarding behavior; and the influence of the three types of features on prediction precision is studied. The experimental results show that the prediction precision of the improved random forest algorithm has less fluctuations, and it is not sensitive to the changes of various features. The improved random forest algorithm has higher precision and better generalization ability than the other algorithms, which shows that the prediction results have high reference value. Social features have the greatest influence on the prediction precision for each prediction algorithm. User features have the similar influence as microblog features on the prediction precision.

Knowledge extraction, data mining, e-learning or web applications platforms use heterogeneous and distributed data. The proliferation of these multifaceted platforms faces many challenges such as high scalability, the coexistence of complex similarity metrics, and the requirement of data quality evaluation. In this study, an extended complete formal taxonomy and some algorithms that utilize in achieving the detection and correction of contextual data quality anomalies were developed and implemented on structured data. Our methods were effective in detecting and correcting more data anomalies than existing taxonomy techniques, and also highlighted the demerit of Support Vector Machine (SVM). These proposed techniques, therefore, will be of relevance in detection and correction of errors in large contextual data (Big data).

Background: Alzheimer’s disease (AD) is characterized by the accumulation of the amyloid-β peptide in the brain, leading to early oxidative stress and neurotoxicity. It has been suggested that physical exercise could be beneficial in preventing AD, but studies with multicomponent training are scanty. Objective: Verify the effects of multicomponent exercise training to prevent deficits in recognition memory related to Aβ neurotoxicity. Methods: We subjected Wistar rats to multicomponent training (including aerobic and anaerobic physical exercise and cognitive exercise) and then infused amyloid-β peptide into their hippocampus. Results: We show that long-term multicomponent training prevents the amyloid-β-associated neurotoxicity in the hippocampus. It reduces hippocampal lipid peroxidation, restores antioxidant capacity, and increases glutathione levels, finally preventing recognition memory deficits. Conclusion: Multicomponent training avoids memory deficits related to amyloid-β neurotoxicity on an animal model.
Pythagorean fuzzy full implication multiple I method and corresponding applications
Authors: Nan TaiBen , Zhang Haidong , He Yanping
Published: July 2021

The overwhelming majority of existing decision-making methods combined with the Pythagorean fuzzy set (PFS) are based on aggregation operators, and their logical foundation is imperfect. Therefore, we attempt to establish two decision-making methods based on the Pythagorean fuzzy multiple I method. This paper is devoted to the discussion of the full implication multiple I method based on the PFS. We first propose the concepts of Pythagorean t-norm, Pythagorean t-conorm, residual Pythagorean fuzzy implication operator (RPFIO), Pythagorean fuzzy biresiduum, and the degree of similarity between PFSs based on the Pythagorean fuzzy biresiduum. In addition, the full implication multiple I method for Pythagorean fuzzy modus ponens (PFMP) is established, and the reversibility and continuity properties of the full implication multiple I method of PFMP are analyzed. Finally, a practical problem is discussed to demonstrate the effectiveness of the Pythagorean fuzzy full implication multiple I method in a decision-making problem. The advantages of the new method over existing methods are also explained. Overall, the proposed methods are based on logical reasoning, so they can more accurately and completely express decision information.

Published: July 2021

The membership functions of the intuitionistic fuzzy sets, Pythagorean fuzzy sets, neutrosophic sets and spherical fuzzy sets are based on three dimensions. The aim is to collect the expert’s judgments. Physicians serve patients in the physician selection problem. It is difficult to measure the service’s quality due to the variability in patients’ preferences. The patients physician preference criteria is differing and uncertainties. Thus, solving this problem with fuzzy method is more appropriate. In this study, we considered the physician selection as a multi-criteria decision-making problem. Solving this problem, we proposed a spherical fuzzy TOPSIS method. We used the five alternatives and eight criteria. The application was performed in the neurology clinics of Konya city state hospitals. In addition, we solved the same problem by the intuitionistic fuzzy TOPSIS method. We compared the solutions of two methods with each other. We found that the spherical fuzzy TOPSIS method is effective for solving the physician selection problem.
