Introduction: it is shown that when organizing the collection of short digital messages in a trunking radio communication network, service request communication channels can be used, transmitting packets-requests to establish a connection. With this approach, the question arises about the size of the bandwidth of the request communication channel, allocated for collecting information, at which the fulfillment of the requirements for establishing a connection will be preserved. Purpose: the purpose of the work is to develop a methodology for calculating the timeliness of transmission of requests for establishing a connection in the context of transmission of short digital messages This technique is the basis of the technique for determining the bandwidth of the request communication channel, allocated for solving the problem of collecting short digital messages. Results: A mathematical description of the revealed feature was carried out, which is the scientific novelty of the research results. An analytical rule for calculating the matrix of transition probabilities and the procedure for calculating the vector of initial probabilities of the request transmission process are presented, which allow, based on the Kolmogorov-Chapman equation, to mathematically describe the request transmission process based on the random multiple access algorithm and calculate the probabilistic-temporal characteristics of the request transmission. The method of calculating the probabilistic-temporal characteristics of the request transmission based on the compiled mathematical model of the request transmission and the mathematical model of the operation of the request channel is presented. The effect of taking into account the revealed features is shown, expressed in increasing the timeliness of the request transmission. Practical relevance: Formed a methodology, which is the basis of the methodology for determining the optimal values of the parameters of the double use of the request channel, which makes it possible to organize the transmission of deterministic traffic of short digital messages over the request channel with a given level of timeliness of transmission of requests to establish a connection. Discussion: the use of the developed methodology will allow organizing a periodic collection of short digital messages in the trunking radio access network without using traffic channels.

Introduction: the most promising approach to the creation of critical distributed information systems is the use of modern information technologies. In this regard, it is of great interest to study the possibilities of building systems of this class based on blockchain technology, which, unlike traditional transactional technology, involves distributed data storage with the formation of a distributed ledger. Purpose: the purpose of the research is to develop a conceptual framework for such an approach, covering the features of blockchain technology. Methods: the goal is achieved by conducting a comparative analysis of blockchain technology and transactional technology, developing an algorithm for the functioning of the system, determining the order of interaction between governing bodies and forming criteria for building a system based on blockchain technology. Results: the results of a comparative analysis showed that the introduction of blockchain technology into critical distributed information systems increases the efficiency of data collection and the availability of information resources stored and transmitted within the system. The developed algorithm for the functioning of a distributed information system based on blockchain technology contains three stages, during which, through the use of hash functions, converting the content of the transmitted document into a digital fingerprint and distributing a chain of data blocks across all network nodes, distributed data storage and complete security are ensured. Practical relevance: the considered order of interaction between governing bodies and exchange of information resources in a system based on blockchain technology demonstrated the possibility of practical implementation of this technology in a critical distributed information system and made it possible to form criteria for its construction. Discussion: as the main criteria, the coefficients of the timeliness of information exchange and the availability of information resources are proposed. To satisfy these criteria, in the search for optimal combinations of parameters for the implementation of blockchain technology, the simulation model of the functioning of a critical distributed information system based on blockchain technology should be used, which is considered as a further research direction."

The goal is to improve the quality of information interaction of objects by increasing the reliability of message delivery to recipients and bandwidth through the integration of networks using various signals and physical channels. A search for new technical solutions for the creation of integrated (hybrid) communication technologies aimed at expanding the possibilities for creating adaptive, self organizing, resistant to destabilizing factors communication systems with an increased quality of services provided in vast areas was carried out. The method of solving the tasks is based on the analysis of development trends and forecasting the requirements for integrated mobile communication systems. The novelty lies in the development and evaluation of options for building the structures of integrated communication systems, represented by diverse, complementary subsystems using various methods of channel separation, including in physical environments, as well as algorithms for their operation. Key findings. A set of technologies for the development of coastal integrated communication systems has been developed: the structure of the system based on a hybrid mesh topology; the basic form of the carrier signal with controlled parameters depending on the physical channel; the principle of control of orthogonal signals in adjacent channels of switching and relay nodes, as well as between network nodes; hydroacoustic communication method. Hydroacoustic communication for coastal areas is a potential for increasing the number of simultaneously used information channels per unit of the volume of interaction of vital objects and makes it possible to connect satellite, air, surface, underwater and bottom subsystems of telecommunications.

Introduction. The issues of the development of digital communication technologies, their implementation and the development of new high-speed data transmission standards, which entail finding more efficient ways to use the allocated frequency band, which allows for the transmission of more data in a narrower frequency band, are considered. Reducing the required frequency band at a given data transfer rate is achieved by sending more bits using a single character. Methods: The main directions for improving modern digital communication technologies are the search for ways to use allocated frequency bands, which will be more efficient, i.e. will increase the amount of transmitted data while reducing the allocated bandwidth. The use of signal multiplexing techniques such as QAM and OFDM signal shaping reduces the occupied bandwidth to approximately the symbol rate. Bit error probability is one of the most important indicators of the efficiency of a communication system. Issues related to the analysis of the bit error probability depending on the signal-to-noise ratio in the communication channel received fundamental and comprehensive consideration. At the same time, the relationship between bit error probability and frequency stability is less explored. Research results: The solution of this problem is possible by changing the amplitude and phase of the carrier between many discrete states of a large number of carrier frequencies with a low channel speed. Based on this, the article discusses issues related to the representation of the signal in the communication channel, taking into account the occurrence of fluctuations in amplitude, frequency and phase from nominal values. The conditions for the influence of constant and random components of the signal frequency deviation from the nominal value on the probability of a bit error are formulated. To implement the formed conditions, the results of mathematical modeling are presented, confirming the correctness of the theoretical results obtained and the main patterns noted.

We have presented performance analysis of E-V-BLAST and according to this analysis, we found some useful characteristics of the E-V-BLAST algorithm for performance and complexity trade-off. Increasing S is applying ML detection with depth T for some most error likely signals. Increasing T is improving the ML detection with depth T. Increasing T will not affect so much to the performance of E-V-BLAST at high SNR. The importance of increasing T depends on S. Recently, a new detection algorithm for the Vertical Bell Laboratories Layered Space Time (V-BLAST) system, which we call Enhanced-V-BLAST, or simply E-V-BLAST, was proposed. In the present paper, we analyze the performance of E-V-BLAST as a function of the two inherent adjustable parameters of E-V-BLAST. On the basis of this analysis, we obtain some useful characteristics of the E-V-BLAST algorithm which allow one to achieve the desired performance and complexity trade-off.

The use of chaotic systems in communications approaches the threshold for industrial applicability. We shall give here an overview over a few techniques we think are promising. However, this overview does not pretend to be complete and it contains personal views on the subject. Also, the use of chaotic system for information encryption is not discussed at all. Only a choice of methods for coding and modulation for the transmission of digital information will be presented. An overview of a number of techniques to transmit information using chaotic systems is given. The difficulties in obtaining a good performance of such systems with respect to channel noise leads to fundamental question, to which we give a possible answer. Given the generally mediocre performance of such approaches, we have identified two fundamental questions which should help us pinpoint the main problems with the existing approaches with the help of information theory and communication theory. In particular it has been confirmed both in theory and by a constructive approach leading to a controlled variant of CSK, that indeed the information generated by free running chaotic systems (as captured by the Kolmogorov-Sinai entropy) is the problem, and the solution is a suitable control that makes this information part of the payload.

Authors:   Gdansk University of Technology, Koziel Slawomir
Published: January 2023

In the paper, a general structure of integrator-based continuous-time Active-RC filter is presented. More specifically, filter structures containing inverting amplifiers and passive feedback network are considered. The structure is analyzed using matrix description. The extensions of the model that take into account finite DC gain and finite bandwidth of operational amplifiers as well as other non-ideal effects are presented. The matrix-based approach is formulated especially for efficient use in computer analysis and design of Active-RC filters. An application example of the proposed approach to obtain OPAMP specifications for 3rd order low-pass Chebyshev filter for Analog Front End for VDSL is given. In this paper, we consider a general Active-RC filter topology suitable for computer-aided analysis, design and optimization of Active-RC filters. The structure is not the most general one, since it is restricted to filter topologies containing only inverting amplifiers (especially integrators) and RC feedback network.
A NEW PRE-DISTORTION APPROACH TO TWTA COMPENSATION FOR WIRELESS OFDM SYSTEMS
Authors:   University of California, de Figueiredo Rui J. P. , Lee Byung Moo ,   University of California
Published: January 2023

Orthogonal Frequency Division Multiplexing (OFDM) has several desirable attributes which makes it a prime candidate for a number of emerging wireless communication standards. However, one of the major problems posed by OFDM is its high Peak-to-Average-Power ratio (PAPR), which seriously limits the power efficiency of the High Power Amplifier (HPA) because of the nonlinear distortion resulting from high PAPR. The present paper presents a new mixed computational/analytical approach for compensation of this nonlinear distortion for the case in which the HPA is a Traveling Wave Tube Amplifier (TWTA) with time-varying characteristic. TWTAs are used in wireless communication systems when high transmission power is required as in the case of the digital satellite channel. Compared to previous pre-distorter techniques based on LUT (Look-Up Table) or adaptive schemes, our approach relies on the analytical inversion of the Saleh TWTA model in combination with a nonlinear parameter estimation algorithm. This leads to a sparse and yet accurate representation of the pre-distorter, with the capability of tracking efficiently any rapidly time-varying behavior of the TWTA. Computer simulations results illustrate and validate the approach presented.

The development of experimental quantum physics in recent years has led to the fact that the abstract ideas of quantum mechanics began to find practical application for the protection of information in a rapidly developing field such as fiber-optic communication lines (FOCL). On the basis of (smart) translucent SMART mirrors, optical splitters, switches, schemes of unidirectional, counter, bidirectional and universal multiplexers and demultiplexers, and the principle of distributing quantum encryption keys between authorized users have been developed. It is shown that it is possible to improve the speed of the process of switching and multiplexing of information flows in comparison with traditional mechanical switches. The paper proposes a circuit solution for an all-optical network (All-Optical Networks – AON) with the possibility of generating and distributing quantum encryption keys between authorized users. The aim of this work is to develop a principle for constructing quantum systems for the secure distribution of encryption keys on all-optical networks between selected (4 or more) users, as well as methods for generating, transmitting and receiving these keys in real time. In this regard, there is a need to develop a switch and a multiplexer of information flows.
INDUSTRY 4.0 TO YOUR INDUSTRIAL CAMPUS

Published: January 2023

The Fourth Industrial Revolution, 4IR, or Industry 4.0, conceptualizes rapid change to technology, industries, and societal patterns and processes in the 21st century due to increasing interconnectivity and smart automation. A part of this phase of industrial change is the joining of technologies like artificial intelligence, gene editing, to advanced robotics that blur the lines between the physical, digital, and biological worlds. Throughout this, fundamental shifts are taking place in how the global production and supply network operates through ongoing automation of traditional manufacturing and industrial practices, using modern smart technology, large-scale machine-to-machine communication (M2M), and the internet of things (IoT). This integration results in increasing automation, improving communication and self-monitoring, and the use of smart machines that can analyze and diagnose issues without the need for human intervention. Amid the hype surrounding Industry 4.0, IIOT, and digital transformation, the introduction of Industry 4.0 has caused a bit of a culture shock for manufacturers. The benefits of data-driven manufacturing are far too significant to ignore and will enable many to deliver competitive advantages in an ever-competitive landscape. Digital transformation is about changing business models and about companies not just taking advantage of the huge opportunities created by these latest technologies but also preparing for their constant evolution. These new models for technology-enabled manufacturing have already moved into the implementation phase by many of the world’s top manufacturers. However, a great deal of hesitancy exists for many manufacturers to embrace the technology and modernization that solves these new challenges.

The research answered its main question: What is the legal ruling on hysterectomy for the mentally disabled women in order to stop the menstruation? In order to answer that, it aimed at clarifying the image of the issue at hand, defining the mentally handicapped, reviewing the benefits and harms resulting from the process, and clarifying the legal ruling for it. The originality of the issue under study emerges as one of the innovations in jurisprudential medical issues that actually occur. The research followed the descriptive method, with the benefit of the inductive and analytical method. It is divided into three sections; It dealt with: introductions and precursors to the definition of research terms, facts and medical studies that pave the way for understanding the issue and its medical background, then the legal theory of the human relationship with his body and the rooting of the issue of the organ removal, then the jurisprudential opinions regarding the removal of the womb of the mentally handicapped to stop the menstruation and the evidence for each opinion and the weighting between them. The research concluded with results, the most important of which are: that international medical studies confirm the absence of an ideal strategy to stop menstruation without serious consequences, whether by surgical intervention or non-surgical alternatives, and that doctors and jurists are between a prohibition and permission to this surgery. The researcher suggested banning the operation for medical and legal reasons, the most important of which are: the side effects it causes and because its harms are greater than its interests.
Key words: hysterectomy, disabled-women, mentally, menstrual.

Neste artigo, buscamos investigar de que maneira as práticas matemáticas, no contexto da educação e do ensino da disciplina de Matemática, podem colaborar para uma estética da existência. Para tanto, mobilizamos as noções de numeramento ou letramento matemático e numeramentalidade para problematizar processos de subjetivação a partir da condução das subjetividades com base nos saberes advindos dos números em vivências relacionadas às experiências proporcionadas na educação básica. Neste estudo, de cunho teórico, optamos por uma construção argumentativa a partir de três cenários, quais sejam: (i) educação financeira; (ii) Olimpíadas Científicas e (iii) veiculação de notícias falsas, práticas de letramento matemático — a fim de possibilitar um melhor entendimento da numeramentalidade, abrindo espaços para a possibilidade de uma estética da existência. Nesses três cenários, procuramos evidenciar o poder dos números para balizar formas de vida e a emergência de movimentos de contraconduta como modos éticos e estéticos de (auto)governamento.

Coarctation of the aorta is a congenital heart disease most often discovered in the neonatal period but can be diagnosed later in older children or even in adults. High blood pressure is the main manifestation in adulthood. Authors reported the case of a 21-year-old patient referred for intermittent claudication associated with grade III high blood pressure in whom the examination showed a blood pressure asymmetry with a gradient of 65mmHg between the upper and lower limbs. Cardiac ultrasound showed bicuspid aortic valve associated with flow acceleration at the aortic isthmus with diastolic extension. Thoracic angioscan confirmed the coarctation of the aorta.
An Approach to Opioid Use Disorder Management
Authors: Chhatre Akhil M
Published: January 2023

This article addresses the challenges involved with transitioning a pain practice away from chronic opioid management. The best approach is to avoid long term opioid therapy (LTOT) when possible and taper off opioids where appropriate. The management of patients with opioid use is complex with psychiatric comorbidities and poor coping skills often impeding opioid cessation. A multidisciplinary approach with frequent involvement is the most effective approach for dose reduction and discontinuation.

A tanulmány röviden bemutatja a gamifikáció (jákosítás) módszerét, majd annak egy alkalmazási lehetőségét az ének-zene tanításban. A módszert olyan 7. osztályokban próbáltuk ki, ahol a tanulók nem tanulták emelt óraszámban az éneket, és nem is tartozott az ének-zene a kedvenc tantárgyaik közé. Az újfajta tanítási módszert a zenei romantika témakörén belül valósítottuk meg három tanórán keresztül. Pedagógiai kísérletünkben kontrollcsoportos vizsgálati elrendezést alkalmaztunk. A gamifikáció tanórai felhasználásával sikerült jelentősen növelni a tanulók motiváltságát. A gamifikáció új módszertani elem lehet az ének-zene tanításában, mellyel a tanárképzésben is érdemes foglalkozni. A tanulmányban bemutatott módszer ötleleteket adhat más tantárgyak tanításához is.

In this paper presents the controlling the power of using quasi-Z source inverter for renewable source application. The proposed quasi z source is single stage DC to AC converter it delivered buck-boost operation with respect to input. These buck-boost converter is highly suitable compare to the normal dc to dc converter for photovoltaic applications. The proposed single stage converter are reliable and suitable for renewable energy source application. The source impedance quasi network offers high gain compare to the exciting system and reduced the total harmonic level. The quasi-z source followed by single phase H bridge converter uses to convert DC to AC with high reliability output. A proposed system-built Simulink and the hardware made for the open loop control. The conventional voltage and current source inverter have its own limitation of the output voltage low compare to the input source in the voltage source inverter, it is just opposite in the current source inverter. These limitations overcome by designed novel modified z source inverter was developed and controlled pulse using unipolar and bipolar concept. The output of the inverter after filter, it produces the less harmonics result 7.6% on fifth harmonics level compare with conventional inverter.

World is running fast. With the speed of communication technology, there is a boom in the transportation industry also. The transportation vehicles are operating day and night to provide proper support of the need. This is really tiring for the transportation workers, especially the drivers who are driving the vehicle. A slight negligence of a driver may cause huge loss. The increasing number of road accidents are therefore a big concern. There is huge research going on to comfort the drivers and increase the security features of vehicles to avoid accidents. Here is this work, a model is proposed, which can efficiently detect driver drowsiness. The work mainly focused on building the learning model. A modified convolutional neural network is built to solve the purpose. The model trained with a dataset of 7000 images of open and closed eyes. For testing purposes, some real-time experiments are done by some volunteer drivers in different conditions, like gender, day, night, etc. the model is really good for daytime and if the driver is not wearing any glass. But with a glass in the eye and in night condition the system needs improvements.

Con los adelantos tecnológicos y la globalización, la población a nivel mundial han aumentado su expectativa de vida lo cual resulta en un indicador positivo, sin embargo y en contraposición se observa un aumento de la prevalencia de enfermedades crónicas. Se hace necesario ahondar en este tema para buscar soluciones y mejorar la salud de las poblaciones envejecientes. El objetivo de este trabajo fue identificar los determinantes de salud que puedan tener incidencia sobre la Hipertensión Arterial en personas mayores de 18 años del cantón Rumiñahui. Metodología: fue un estudio de tipo descriptivo, transversal, con enfoque cualitativo en una muestra de 120 personas. Se aplicó un cuestionario con 32 preguntas cerradas dicotómicas y politómicas en personas del sector urbano y rural del cantón. Resultados en el bloque correspondiente a la Biología humana prevalecieron personas entre 18 y 30 años de edad, siendo el sexo femenino el de mayor incidencia con 78 mujeres, destacando que el consumo de alcohol esta con un 33 % siendo este el hábito más preponderante en los hombres, 12 mujeres sedentarias para un 15% predominó en el bloque del Estilo de Vida, se observa que es el que presenta la frecuencia más alta, ya que las personas tienden a mantener conductas poco saludables lo cual tendrá influencia en la aparición de Enfermedades Crónicas no transmisibles entre ellas la hipertensión arterial, se concluyó que los determinantes de salud relacionados con los estilos de vida están asociados con el sexo femenino y es el determinante con mayor preponderancia y el cual puede influir sobre la posible aparición de hipertensión arterial. Se sugiere trabajar en la elaboración de estrategias para fomentar modificación de conductas hacia estilos de vida más saludables.
