Access to Education of Syrian Refugees Living in Türkiye
Authors: AYDIN Yusuf
Published: September 2022

2011 yılında Suriye iç savaşının başlamasından sonra milyonlarca insan canını kurtarmak için kaçmak zorunda kaldı. Devam eden göç dalgaları birçok sorun yarattı. Bu sorunlardan biri de savaştan en çok etkilenen gruplardan biri olan mülteci çocukların eğitimidir. Bu mültecilerin çoğu, bu insani krizden en çok etkilenen ülkelerden biri olan Türkiye'ye gitti. Suriyeli mülteci çocukların bir kısmı kamplarda yaşarken bir kısmı kamp dışında farklı şehirlerde yaşıyor. Bu çalışma, kamp dışında yaşayan Suriyeli mülteci çocukların durumu ile kamp içinde yaşayanların durumunu karşılaştırmaktadır. Çalışmada bu konuyu ele alan farklı yazarların görüşlerini ortaya koymak da hedeflenmektedir. Çocukların eğitime erişimi hem uluslararası hukuk hem de iç hukuk açısından kaçınılmazdır. Ancak kamp dışında yaşayan bu mülteci çocukların, dışarıdaki yaşamları daha zor olduğu için ailelerinin geçimini sağlamak gibi bazı temel sorumlulukları bulunmaktadır. Türkiye Cumhuriyeti yardım ve eğitim olanakları sağladığı için kampta yaşam nispeten daha kolay olduğu düşünülmektedir. Bu araştırma, kamp dışında yaşayan çocukların eğitim sistemine entegrasyonunun daha zor olduğunu göstermektedir. Öte yandan, devlet destekli kamplarda yaşayanlar için sosyal ve eğitim olanaklarına erişim daha kolay ve hızlıdır.

Introduction
Klippel-Feil Syndrome is a complex condition, characterized by fusion of cervical vertebrae 2 and 3; however, it has been shown in several studies that fusion of the vertebrae also affects different cervical vertebrae. It is caused by a failure of the normal division or segmentation of the cervical vertebrae in early fetal development. This anatomical variant can lead to chronic headaches, limitation of neck movement and pain in the neck muscles. In addition, it may manifest neurological symptomatology (1)(2).
The aim of this literature review is to consider this malformation as one of the main differential diagnoses in patients who present neurological symptoms or a history of trauma; since, as has been shown, the presence of this malformation can be confused with the presence of a cervical fracture; therefore, patients who present with clinical or imaging alterations need to be carefully evaluated to confirm or rule out the presence of this pathology.
Conclusions
Klippel-Feil, being a very rare pathology, is often forgotten, so the doctor must remember the most important clinical-epidemiological characteristics, since this pathology can be considered as a differential diagnosis in patients with a pathological condition located in the cervical region; in addition, this pathology should be considered when the patient has systemic pathologies, especially of the renal type.
KEY WORDS: Klippel-Feil syndrome, cervical spine, congenital spinal fusion, radiological abnormalities.
Estimation of energy intensity of subscriber radio lines and information capacity of the LEO satellite system of the internet of things
Authors:   Moscow Institute of Physics and Technology, Duc Anh Nguyen
Published: September 2022

It is clear that the importance and impact of the Internet of Things on all areas of life is undeniable today. To implement the connection and exchange of information between objects, one cannot fail to mention wireless networks, LPWAN networks ... However, the above networks still have some limitations that need to be overcome, such as coverage areas, signal delay and some other special features. Therefore, research and development of a satellite system with the IoT function is very promising and relevant. In addition, in order to compete with terrestrial networks in terms of equipment cost, service cost, and ease of operation and use, it is necessary to create satellite networks to work with terrestrial networks. The result of the analysis of LPWAN technologies in terrestrial networks showed that Lora technology is the most suitable for working with a satellite system. The article presents an assessment of the energy of subscriber radio lines when the satellite system is compatible with the Lora network. It is shown that the protection against interference on the "Earth-spacecraft" link is not less than 6-8 dB (worst case). The required reserves in the subscriber radio lines of the OFF-Line mode have been determined. Calculations of the information capacity of the IoT satellite system were carried out and the maximum data package of the consumer's subscriber facility was determined.

Mathematical models of motor traffic flow on highway sections on highway sections near intersections or flow segregation sections are considered. In these models, the particles corresponding to motor vehicles move according to probabilistic rules along a cellular field that moves at a constant speed in the direction coinciding with the direction of movement of the particles. A cell field consists of sequences of cells. Each such sequence corresponds to a lane on the highway. The time scale in the model is discrete or continuous. The model is a dynamic system with a discrete state space and discrete or continuous time. The mathematical description of the model can also be presented in terms of a cellular automaton or a random process with prohibitions. At any given time, there is no more than one particle in each cell. With each movement, the particle either moves one cell in the direction of movement, or moves to the next lane, or remains in place. The speed of the traffic flow on the highway section corresponds to the sum of the set speed of the cell field and the average speed of the particles relative to the field. The studied characteristics are the speed of the traffic flow, its intensity and the probability of successful rebuilding of the vehicle on the considered section of the highway. When setting the parameters of the model, data from measurements of the characteristics of traffic flows on highways are used. Analytical approaches have been developed to evaluate the studied characteristics. Computer programs have been created to implement the developed calculation algorithms. The results of calculations are given.
Iterative algorithm for offset and scale estimation for 1d signals superposition with additive and multiplicative noise
Authors:   Povolzhskiy State University of Telecommunications and Informatics, Diyazitdinov Rinat R.
Published: September 2022

We describe the algorithm for 1D signal superposition. The superposition is defined by offset and scale. Also the signals contain additive and multiplicative noise. We developed the iterative procedure for superposition of those signals. This procedure includes the separate estimation of offset and scale. The offset is estimated by signals in the Cartesian coordinate system. The scale is estimated by signals in the logarithm coordinate system. The iterative method is approximation to real value of superposition parameters. The parameters of the current iteration depend on the estimation of previous iteration. The error of the parameters estimation from additive gauss noise was by the numerical simulation. The developed algorithm compares with the brute force algorithm (the etalon algorithm). The compassion show that both algorithms are characterized the similar error of the parameters estimation, but developed algorithm is faster.
Method for determining the target direction of a digital antenna GRID OF A MONOPULSE radar station
Authors:   Mints Radio-Technical Institute, Shatskiy Nikolay V. , Hodataev Nikolay А. ,   Mints Radio-Technical Institute
Published: September 2022

On the basis of the analysis of the errors of the monopulse method of direction finding of the target of a radar station with a digital antenna array, a group of errors associated with fluctuations of the equisignal direction when scanning the beam of the antenna system, as well as with the non-identical shape of the generated beams of the monopulse group, was separated into a special cluster. This circumstance is especially critical for large-aperture radars with phased array with electric scanning, where the number of formed receiving beams is significant, in addition, the coordinates of the target usually do not coincide with the coordinate planes along which the coordinates are measured. The nonlinearity of this problem requires unique approaches and solutions. The classical formulation of the problem is associated with obtaining an estimate of the radiation vector of the entire antenna array from the known measured vector of complex signals at the output of the antenna array at a fixed time. To solve this problem and determine the decision rule, a neural network approach was used, while the neural network was trained according to the criterion of the minimum of the selected objective function. The substantiation of increasing the accuracy of measurements of angular coordinates in monopulse systems with scanning digital phased antenna arrays based on the use of neural networks in the process of radar data processing without the formation of direction finding characteristics is given. The results of modeling the characteristics of the antenna array (using the example of a flat antenna array with a dimension of 30 by 30 emitters) under the conditions adopted in the model of the antenna array of assumptions when implementing the classical and original methods are shown using examples of the surfaces of the variances of errors in measuring angular coordinates by the monopulse method in a rectangular spatial domain, which showed reduction of error and expansion of the measurement area. In the future, the practical implementation of this approach is assumed using FPGA in the receiving paths of the frequency-dependent part of the radio direction finder.
Development of a program for calculating additional distortions for various models of errors
Authors:   Moscow Technical University of Communications and Informatics, Kudryashova Anastasia Yu.
Published: September 2022

When transmitting signals from a source to a receiver, their multiple transformations take place. At the same time, various types of spaces bijection in which signals are displayed allow minimizing additional distortions arising from errors in a discrete communication channel, or reducing the probability of a bit error when distortions occur in a continuous communication channel. This optimization of the choice of the bijection type is largely determined by the error model or, respectively, by the model of the acting noise, which cannot always be displayed in the form of an analytical expression, with the help of which the necessary transformations and calculations can be carried out in the future. In this regard, it is advisable to develop a software model in which it is possible to specify various types of errors, for which further calculations of the optimal types of spaces bijection that minimize the probability of bit errors, or, accordingly, the amount of additional distortions, can be carried out. This article discusses the problems associated with evaluating the efficient coding of a signal source. For this, an algorithm and a program for evaluating the effective coding of a signal source for the currently widely used analog-to digital conversion of a continuous signal into a binary signal are proposed. The results of this study will be useful in this in the implementation of the optimization of the arising distortions taking into account all influencing factors in the system as a whole.

It is expected that future communication networks will provide configurable delay-sensitive types of services (for example, streaming video, machine interaction). To support a variety of applications and use cases of servers providing various functions, you can use network function virtualization (NFV), which will be able to provide flexible implementation and placement of configuration of the necessary network functions. This article analyzes the end-to-end packet latency (E2E) for multiple traffic flows passing through the chain of embedded virtual network functions (VNF) in fifth-generation communication networks (5G). The Dominant of Generalized Resource Processing (DR-GPS) is used to distribute computing resources and transfer data between threads in each node of Network Function Virtualization (NFV) to achieve equitable distribution and utilization of available resources. The tandem queuing model is designed for incoming packets combined in several streams passing through the NFV node and its outgoing transmission channel. To analyze manageability, we separate packet processing (and transmission) of various streams in the simulation and determine the average packet processing and transmission rates of each stream as approximate service speeds.

An extended section of the railway line was chosen as the subject of the researching. The section under consideration is a set of separate points for various purposes: intermediate, cargo, precinct and marshalling stations. This structure is a system of interacting elements. The purpose of the research is to create a method for identifying factors that affect the throughput of the railway section, and the formation of a set of recommendations to minimize the impact of these factors on the implementation of transportation processes. The main tool for conducting research is simulation modeling, which makes it possible to represent the area under consideration as a system consisting of several elements. Each element has its own set of properties that directly affect the system as a whole. The main results of the research include the construction of a simulation model of transport processes on the considered section of the railway line. On the basis of the generated model, the possibilities of assessing changes in the traffic flow passing through this section are considered, taking into account all the key elements of the transportation process. These include the type of train, the number of cars in the composition, the speed of movement, travel times, etc. The obtained results can be applied when conducting a comprehensive assessment of the functioning of existing railway lines. Also, based on the data obtained, it is possible to create a database, the content of which will be a data array that takes into account irregularities, failures of technical devices, and the occurrence of emergency situations. Based on the research, a method is proposed for estimating the throughput of an extended section of a railway line using a specialized Anylogic application package.

Due to the progressions in the cellular technologies in recent times, communicating networks have seen vast expansion in the volumes and multiplicities of the data transmitted over the enhanced smart network especially IoT. The regulation and organization of such enormous amounts of data is posing substantial challenges across the various network industries. Because majority of data traffic transferred over such complex networks is comprised of "Big Data" That is continuously growing and evolving. 3GPP have acknowledged such scenarios and have given several recommendations and procedures to manage resources in such situations. But regrettably there are no concrete explanations and techniques on how these resources should be distributed in heterogenous networks. The mathematical modeling that considers the characteristics of traffic flows originating and accepting for servicing is deemed as one of the critical answers to such problems. To address this issue, we have designed a model of resource allocation and sharing strategy for conjoint servicing of real time video traffic referred as "Heavy traffic" of surveillance cameras and low-quality video traffic, referred as "Light traffic" which are transmitted as files over LTE cell facilities in a surveillance operator system. In the model, the access control is incorporated to create the conditions for differentiated servicing of heterogenous traffic incoming sessions. The mathematical model can be utilized to study reservation-based resource allocation scenarios over a shared heterogenous network.

Low latency is an important indicator for satellite communication systems on geo earth orbits (GEO). Transmission delay in packet networks includes access delay, propagation delay, and processing delay. The processing delay depends on the performance of the processing methods and system overload management, which is just a small fraction of the total transmission delay at low traffic load. This article dis-cusses the latency of a terminal accessing a network after a connection break. The paper proposes the scheme for maintenance a user terminal synchronization in a satellite communication net-work with bandwidth pre-assignment. The scheme is based on a traffic prediction and not requires a request from the terminal. The place of the proposed scheme in the synchronization maintenance system of the DVB-RCS2 standard is defined. A comparison of the performance of predictive traffic models is given. The latency reduction and the signal-to-noise ratio operating range extension of a user terminal from the use of the proposed scheme for maintaining synchronization is presented. The paper also presents an overview of the application of data analysis methods in the tasks of the time-frequency resource allocation in a GEO satellite communication system.

Time synchronization systems in communication networks must be linked to the reference time scale (TS) of national standard. In most cases, receivers of global navigation satellite systems (GNSS) signals are widely used for these purposes. However, possible violations of these signals reception, as well as cases of their substitution (spoofing) force us to look for alternative options for receiving airwaves via terrestrial communication channels. One of the solutions - use of special equipment for time signals (ARSV) complete distribution with a time server that receives, stores and transmits SH signals to the consumer in any format – NTP, PTP, 1PPS + ToD, etc. The purpose of this article is to present the experience of implementing time-frequency systems using terrestrial communication channels with UTC time scale sources.
PERFORMANCE OF A CONTINUOUS SOLAR WATER DISINFECTION SYSTEM IN ISIOLO COUNTY, KENYA
Authors: A.E. Onyango
Published: September 2022

A continuous solar water disinfection system was designed, installed and tested in Isiolo town, Kenya. The system consisted of two flat plate solar collectors each having 2.34 m2 gross area and photovoltaic pumping system. International Organization for Standardization (ISO) analytical procedures; ISO16649-3, ISO 6888-2, ISO 4833-1, ISO 9308-, ISO 10523:2017 ISO 7027: 2016, and ISO 7887: 2011 were used to determine the quality of disinfected and untreated water. The experimental design consisted of series collectors without heat exchanger, parallel collectors without heat exchanger and series arrangement of solar collectors with heat exchanger for preheating the cold incoming water using the exiting hot water. Total coliforms, total plate count, Staphylococcus aureus and Escherichia coli log10 counts in raw water were: 3.4, 3.8, 2.3 and 2.1 respectively. The mean Log10 reductions in total coliforms, Escherichia coli, Staphylococcus aureus and total plate counts were; 3.3, 1.9, 1.9 and 3.7 respectively in series arrangement with heat exchanger. Inactivation to < 1 CFU/ml was attained using series collector’s arrangement with heat exchanger between 12:00 and 14:00. Parallel collector arrangement induced water pasteurization that required recirculation and low flow rates to effectively initiate microbiological inactivation. Staphylococcus aureus requires temperature greater than 48 °C to initiate inactivation. Series collector arrangement with heat exchanger produced 200 l of disinfected water per day. However, additional collectors and water recirculation are required to increase the volume of disinfected water.

Objectives

The purpose of this article is to identify the role of international diplomacy in shaping the outer Space Traffic Management.

Methods

The theoretical research methods were used in this paper – analysis, synthesis, abstraction and generalization.

Results

The article presents the potential possibility of not only gaining the public awareness in the area of space traffic management problems thanks to the international mandate of institutions such as the European Union (EU) or NATO, but also its attempt to indicate the role of European institutions in shaping international security in the context of the development of space traffic management at the global level.

Conclusions

Taking into consideration all potential space threats and military and non- military issues of building international security we can find straight links of complexity with the outer space environment and multilateral diplomacy. It sems to be the most efficient tool to build resilience in the environment of international institutions of strategic status to establish space situational awareness of key importance for future global defence and deterrence. Taking a huge intensity of space traffic management, especially with the example of the tensed conflict in Ukraine since 24th February 2022 we are witnessing the new era of space technological resolutions. The awareness should also concern the possibility of technical achievement, as the example done by Chinese or Russians that can destroy satellites in orbit in case of the possible conflict scenario in the space.

Authors: Napieralska Agnieszka
Published: September 2022

Objectives

Celem niniejszego artykułu było przedstawienie przedstawienie przez autora wieloletniej działalności Rosji w aspekcie produkcji zarówno broni biologicznej jak również chemicznej, a także prowadzeniu przez nią badań nad skutkami wynikającymi z potencjalnego jej użycia. W świetle tak określonego celu ustanowiono następujący problem badawczy, który sformułowano w postaci niżej przedstawionego pytania: czy istnieje prawdopodobieństwo wykorzystania przez Rosję broni biologicznej lub chemicznej podczas trwającej obecnie wojny z Ukrainą?

Methods

Metody badań zastosowane w procesie badawczym obejmowały przede wszystkim dogłębną analizę materiałów źródłowych – aktów prawnych, pozycji zwartych oraz artykułów naukowych dotyczących funkcjonowania na terenie Rosji zakładów produkujących broń masowego rażenia.

Results

Wyniki badań potwierdziły przyjętą hipotezę, że Rosja dysponuje zarówno bronią biologiczną jak i chemiczną, oraz możliwościami do jej wykorzystania. Od dnia napaści zbrojnej na Ukrainę, Rosja dopuszcza się rozmaitych prowokacji, mających na celu usprawiedliwienie ewentualnego użycia tej śmiercionośnej broni. Zweryfikowanie postawionej wcześniej hipotezy wymagało dogłębnej analizy wcześniejszych działań Rosji ukierunkowanych na produkcję oraz badania broni masowego rażenia oraz obserwacji przebiegu toczącej się wojny.

Conclusions

Wnioski z przeprowadzonych badań wskazują na prawdopodobieństwo użycia przez Rosję broni biologicznej lub chemicznej w trwającym obecnie konflikcie zbrojnym z Ukrainą, będące skutkiem dynamiki wojny, pogarszającej się sytuacji ekonomicznej Rosji oraz zastosowania względem niej coraz większych sankcji.
