At present, frequency-shift keyed signals with n discrete states have found wide application in various radio-technical digital communication systems. The main factor holding back their further development is on the one hand the limited currently attainable capacity with a given level of Quality of Service and, as a consequence, the transmission rate, which is due to a complex signal-and-noise environment, intersymbol interference and intersystem interference, and on the other hand, the attainable level of technical feasibility. The main method to increase the transmission speed in such communication systems is the transition to work in the conditions of intersymbol interference. The existing approaches to solving this problem, such as optimal and suboptimal processing methods that transform a channel with memory into a channel without memory, are of little interest because of the poor practical feasibility of the receiver itself, in principle. An alternative approach that solves this problem is the development of communication systems based on the provisions developed within the Theory of resolution time. Expanding the applicability of these provisions to service communication systems, the authors set the goal of developing a numerical method for assessing the capacity of a communication channel with memory caused by the frequency selective properties of a real channel, using frequency-shift keyed signals with n discrete states and a continuous phase. To achieve this goal, within the framework of the paper, the mathematical model of a communication channel with memory for frequency-shift keyed signals with n discrete states and continuous phase was developed, taking into account the measurement errors introduced by the receiver for determining the physical envelope and instantaneous frequency. This, in particular, makes it possible to analyze the influence of the frequency instability of the synthesizer employed in real radio-technical information transmission system on the reception quality. In this case, the mathematical model allows to optimize the system taking into account the transfer characteristic of the frequency selective communication channel of the signal constellation.

Introduction: it is well known that the use of stegosystems increases the information security of storage and trans mission of confidential information, ensuring the concealment of the content and the very fact of the presence of classified data in "innocent" covering objects, the most important of which are images, sound and text files, and Internet protocols. The stegosystem is used not only by government agencies, but also in the business community to ensure organizational or technical confidentiality. On the other hand, the technology of detecting stegosystems is also relevant, since it allows organizations and companies to protect classified information from its leakage into the external circuit, as is usually done in the Data Leakage Prevention system. Purpose of the study: the purpose is to study methods for detecting a promising stegosystem with the immersion of confidential information into the contours of a still image with grayscale. Results: a method for finding image contours and an algorithm for immersing information in them are described, an assessment of the amount of embedded information, as well as the possibility of detecting an embedding by visual and histogram methods, is carried out. An approach based on pseudo-randomness tests was used as a more efficient detection method. The results of the experiment convincingly showed that this method of steganalysis has an advantage over traditional methods of detecting stegosystems, especially if it is combined with the Support Vector Machine technique. Discussion: however, when information is embedded only in a certain part of pixels using a stegokey, the considered steganalysis method gives only small improvements in detectability, which indicates a fairly high resistance of stegosystems with embedding in image contours

Introduction: Recently, there has been an active development of algorithms for adaptive beamforming. Such work is required in order to improve the efficiency of receiving a useful signal, especially in mobile communication systems. This article provides an overview of research on this topic. Papers devoted to the improvement of the classical least mean square algorithm, blind signal separation methods, antenna selection algorithms in MIMO systems and other topics of adaptive signal processing are presented. Practical relevance: Adaptive beamforming is a key development for modern wireless communication systems, in particular 5G. Increasing requirements that impose a limitation on the spectral bandwidth of the signal and its center frequency with limited signal power lead to the strategy of forming a narrow signal transmission beam, thereby increasing the energy efficiency of signal transmission and reducing the overhead associated with the reception of various interference. This article provides an overview of studies on this topic. The results of the analysis of works devoted to the improvement of the classical algorithm for minimizing the mean square error, blind signal separation, antenna selection algorithms in systems of several antennas, and other topics of adaptive signal processing are presented. Discussion: It is shown that the main directions of research are focused on the improvement of classical diagramming algorithms, as well as on the improvement of methods for receiving digital signals in MIMO systems. Algorithms for recognizing the type of signal modulation, an algorithm for blind separation of second-order signals, an improved algorithm for automatic gain control, an algorithm for suppressing noise-like interference, and an algorithm for estimating radiation pattern parameters were also considered.

Introduction: The class of mathematical traffic models is based on the theory of queuing. In these models, the application entering the service system corresponds to the vehicle. When developing a traffic model formulated in terms of queuing, it is necessary to specify a random flow that is incoming to the queuing system. The purpose of the study: Traditional queuing systems with recurrent incoming flow under appropriate conditions do not reflect the specific features of real traffic flows. Under certain conditions, for example, it may be appropriate to use a Markov-type flow in the model, the intensity of which depends on the state of a mathematical object called the control device. In the general case, such a flow can be specified as non-uniform, and with such a task, each request is assigned a type that also depends on the state of the control device. Setting the qualitative structure and parameters of a random flow depends on the assessment of the speed characteristics of the vehicles that form the flow, and, therefore, is related to the issues of studying the speed characteristics of real vehicles. Practical significance: At a sufficiently low density of the traffic flow, the incoming flow is close to the Poisson one. As traffic increases and road conditions worsen, the risk of overtaking increases and clusters are formed, consisting of a slow car moving in front and a group of fast cars that cannot overtake a slow one. In such cases, we can assume that the incoming flow is a Bartlett flow, which has the following form: clusters form a Poisson flow, and the cluster length distribution is a two-parameter Bartlett distribution. One of the parameters of this distribution is the probability of having a group of fast cars, and the second parameter characterizes the distribution of the number of cars in this group. Discussion: In this paper, we study the questions of setting a qualitative probabilistic structure and quantitative parameters of random flows, which are elements of queuing systems used as traffic models.

Published: September 2022

Introduction: the functioning of a communication node under the influence of destabilizing factors is a complex process, the description of which is a non-trivial task. The random nature of the impact, as well as the importance of the power supply system, determine the need to create a model that allows adequately describing the process of functioning of both the node itself and its elements. The purpose of the work is to develop a model of the functioning of the communication node under the influence of internal destabilizing factors – failures of elements of the power supply system. Methods used: the use of the apparatus of topological transformation of stochastic networks with the probabilistic method of network planning (GERT) in the field of studying the functioning of the control system, taking into account the impact of failures of elements of the power supply system, allows us to adequately describe the functioning of both the elements (taking into account the specifics of the method of organizing power supply) and the communication node itself under the influence of destabilizing factors, expressed in its functions of the distribution of recovery time and preservation of working condition. The novelty of the work lies in the fact that the peculiarities of the organization of the power supply of each element of the node are taken into account; destabilizing factors are failures of elements of the power supply system, as a result of which it is possible to disrupt or terminate the functioning of the node, which allows determining the probabilistic and temporal characteristics of the functioning of its elements under the influence of destabilizing factors; features and probabilistic-temporal characteristics of the process of restoring the functional state of the node elements, which includes a number of measures for the transition to autonomous sources, a cold reserve power plant, power sources for other consumers. Result: the presented model makes it possible to assess the reliability of the functioning of the communication node and its elements in the conditions of failures of the elements of the power supply system based on the available initial data. Practical significance: the presented model is universal and can be applied to any field communication node.

The purpose of this investigation is to develop a systematic nonlinear analysis of the circuit in Figure 1, as yet not available in the literature, obtaining an exact formula for the oscillation frequency. Then, we find the condition for the circuit to behave as a relaxation oscillator, or as a nearly sinusoidal oscillator, analyzing the circuit behavior around the equilibrium point through a circuit model accounting for the transistor intrinsic capacitances. A nonlinear analysis of the popular emitter-coupled multivibrator is performed, which is based on the classical discontinuity theory. Exact relationships for calculating its waveform are obtained. Then, we investigate the circuit dynamic behavior showing that at very high frequencies the circuit exhibits a completely different behavior, similar to an LC second-order nearly sinusoidal oscillator. Conditions allowing us to predict one or the other behavior are found.

Abstract

 

The purpose of this study is to analyze the history and progress of the Ottoman Turks for the Islamic World. Historically, the founder of this kingdom was a Turkic nation from the Oghuz tribe, whose name was Ertugrul, he was the pioneer of the Ottoman Empire who died in 1289 AD. Later, the leadership was continued by his son, Uthman. Uthman bin Ertugrul is considered the founder of the Ottoman empire. There are nine phases, namely the first and second phases as the pioneering and founding phases of the Ottoman Empire, phases three and four as the glory phase, phases five to 8 as the phase of stagnation, decline and dissolution of the Ottoman Empire, while the ninth phase is the phase of the Republican caliphate. Factors that influenced the glory and progress of the Ottoman Turks were political, military, economic factors, the paradigm of rulers/sultans, and socio-political factors. Meanwhile, the territory of the Ottoman Turks in parts of Asia, North Africa to Eastern Europe can be conquered and maintained for approximately 6 centuries. The heyday of Solomon (King Solomon) was known by his people as the noble title "al-Qanuni". The forms of Ottoman progress were the military and government fields, science and culture, architecture, religion and political management.

Effect of Governance on Macroeconomic Instability in Sub-Saharan Africa: Does Regional Analysis Matter?
Authors: Mofow Neville Zoatsa  , Tafah Edokat Edward  , Molem Christopher Sama
Published: September 2022

Macroeconomic instability is a growth blockage in any contemporary societies, businesses, and governments. However, how to achieve macroeconomic stability remains a gap in extant literature for most developing countries. This study examines the effect of governance on macroeconomic instability in a sample of 42 Sub-Saharan African countries over the period 1996-2019. Four governance indicators, namely political governance, economic governance, institutional governance and general governance are constructed with the use of principal component analysis. Empirical evidence based on the Generalized Method of Moments and alternatively by Two-Stage least Squares technique for regional analysis reveals that the selected governance indicators do not have the same reducing influence on macroeconomic instability in Sub-Saharan Africa. Considering sub-regional analysis, evidence of a positive effect of political governance over growth instability in Central Africa is sparingly apparent in Voice and Accountability, and liberal democracy. This finding therefore recommend, improved local contents of governance policies toward economic sustainability, redesigning and returning the content of democracy in line with the demands, peculiarities and realities of central Africa state.

Coronavirus disease 2019 (COVID-19) is currently a major public health concern causing devastating sociological, economic, and psychological damage to livelihood all over the world. The most intense severity of COVID-19 is not only acute respiratory distress syndrome (ARDS), it also causes multi-organ failure, the post-infection secondary effect as well as death. The fast-mutating ability and high transmissibility rate of the virus cause emergence of the new variants and also the occurrence of breakthrough infections. Evidence suggests that vaccination against COVID-19 has been effective at preventing the severity of illness, hospitalization, and death. The efficacy of vaccines depends on multiple factors including the host’s ability to mount a robust and sustainable immune response, the virus’s ability to mutate its genome, and programmatic factors such as vaccine dose, storage, dosing schedules, etc. In this article, an overview of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, its pathogenesis, host immune responses to infection, and different type of COVID-19 vaccines, including vaccine efficacy and adverse effects are described.

Published: September 2022

A special autonomy policy was implemented in Aceh in 2006, which differed in managing fiscal transfers from the central government. To this end, we examined the convergence of human development in districts/cities for thirteen years (period 2008-2020) as a form of development evaluation from the implementation of special autonomy. Using a sigma convergence approach to panel data sets sourced from the Central Bureau of Statistics (BPS), this study found a slow year-on-year movement of decreasing human development disparities. On the contrary, it can be discovered that solid evidence of absolute convergence in the 2011-2020 period, despite the differences between the 2008-2020 period, was applied. In line with these discoveries, it will take over a decade to achieve a steady state of living standards, equalization, and quality of human development between districts/cities. It could be the basis for policymakers to maintain a sustainable sense of special autonomy.

Published: September 2022

El Estado cuenta con una primera aproximación cuantitativa que dota a los gobiernos con una medición de crecimiento de la producción, renta y gasto en el corto plazo, el indicador del Producto Interno Bruto.

La información que provee posibilita una adecuada planeación de la Política Económica, sin embargo, la dinámica económica en México aparenta encontrarse en una situación inercial que amplía la brecha de ingreso y el rezago social, permeando en las diferentes dimensiones sociales. Dada esta problemática, se destaca la necesidad de contar con indicadores locales racionales que integren al ciudadano en una lógica de conciencia contributiva, esclareciendo el entendimiento común sobre el pago de tributos y su aplicación en el gasto corriente y la inversión pública. El presente trabajo desarrolla un análisis cuantitativo basado en un modelo lineal que permite estimar la distribución del PIB real a nivel municipal, proporcionando un indicador con información oportuna y puntual de la unidad subnacional mínima y de mayor heterogeneidad en el sistema federal.
Problemáticas actuales del Derecho Penal acerca de la noción de bien jurídico y su protección
Authors: Farah Rodríguez Mario Stalin , Durán Ocampo Armando Rogelio
Published: September 2022

Actualmente la teoría del bien jurídico, aunque es comúnmente aceptada por la doctrina y la jurisprudencia, adolece de una delimitación teórica que la ubique definitivamente. El presente estudio tiene el objetivo de analizar las carencias doctrinarias y en el abordaje teórico metodológico en el Derecho Penal que limitan la protección del bien jurídico, con énfasis en la legislación ecuatoriana. Se generó una investigación cualitativa, interpretativa, con alcance analítico, documental, orientada al análisis crítico y argumentado acerca de la protección del bien jurídico y sus problemáticas en el Derecho Penal, mediante el método dogmático y documental. Los resultados indican que la indefinición en torno al bien jurídico es una falencia doctrinal que provoca la indeterminación dentro del sistema jurídico penal. Esta indefinición en la legislación ecuatoriana conlleva tergiversaciones en el cumplimiento de las funciones del Derecho Penal acompañándose de un inadecuado análisis jurídico penal que en ocasiones surge por intereses externos ligados a la política y la distribución del poder.

Objetivo: establecer la prevalencia y caracterización sociodemográfica del Síndrome de Burnout en los colaboradores de la Nueva E.S.E Hospital Departamental San Francisco de Asís de Chocó durante el primer semestre de 2021.

Metodología:  estudio descriptivo de corte transversal que tuvo como insumo la aplicación del instrumento tipo cuestionario Maslach Burnout Inventory Human Services Survey (MBI-HSS) a una muestra de 54 colaboradores del área asistencial de la Nueva E.S.E Hospital Departamental San Francisco de Asís de Chocó. Se tabularon con Microsoft Excel los datos obtenidos, se calculó la prevalencia del Síndrome de Burnout y se describieron características sociodemográficas de los participantes.

Resultados: la prevalencia del Síndrome de Burnout en los participantes fue del 7%, con predominio del sexo femenino, mayor afectación del personal médico y de quienes tuvieron edades entre 25 y 35 años, sin variaciones respecto al tiempo de antigüedad en la institución. Conclusiones: el personal asistencial de la Nueva E.S.E Hospital Departamental San Francisco de Asís de Chocó presentó un bajo porcentaje de Síndrome de Burnout, además se puede inferir que ser mujer y desempeñarse en profesiones como enfermería y medicina aumenta la probabilidad de desarrollar el síndrome.
The Effect of The Inclusion of The Secondary Roof Under the Main Roof on Performance of Chimney Solar Power Plants
Authors: Safer Nabil Belkacem
Published: September 2022

In this work the effect of the inclusion a second roof on the power output of chimney solar power plant (SCPP) were investigated numerically through analytical model. The analytical model presented in this work based on energy balance equations and mass conservation equation at steady state. In second step, the proposed analytical model is then used to estimate the annual electricity production in Sétif, a region of Algeria. For the position of the sun in Setif is 36.19 degrees longitude and 5.41 degrees latitude. It appears from results obtained that the efficiency is increased by 28.7 % for the chimney solar power plant (SCPP) with the secondary roof compared to chimney solar power plant (SCPP) without second roof. It was also concluded that there is an optimal height of the second roof for the power output of chimney solar power plant (SCPP) to remain maximum. It is noted that the energy production increases with the increase in radiation and ambient temperature. However, the solar irradiation is the dominant factor on the electricity production of the chimney solar power plant, compared to the ambient temperature. The results obtained are in good agreement with the experimental results of a prototype plant in MANAZANARES.
Refleksi Keuangan Hijau di Indonesia dan Proyeksi Taksonomi Hijau sebagai Kebijakan Pintar

Karhutla di Indonesia selama ini banyak terjadi di wilayah konsesi perusahaan. Perusahaan yang terlibat karhutla terafiliasi dengan grup-grup besar yang dibiayai oleh bank-bank besar di Indonesia. Selama ini, bank menerapkan aspek kepatuhan sebatas pada persyaratan lingkungan yang ditentukan oleh peraturan perundang-undangan dalam melakukan pembiayaan, yakni melihat ada tidaknya Analisis mengenai Dampak Lingkungan (AMDAL). Oleh karenanya, aspek lingkungan perlu diintegrasikan ke dalam manajemen risiko pembiayaan oleh bank terhadap perusahaan yang berisiko tinggi menyebabkan kerusakan lingkungan. Konsepsi green financing/keuangan hijau perlu diimplementasikan oleh bank dengan mengadopsi berbagai instrumen penataan lingkungan. Pada awal tahun 2022, Otoritas Jasa Keuangan (OJK) mengembangkan taksonomi hijau untuk menerapkan keuangan hijau, yang didasarkan pada jenis usaha dan menggunakan kode warna seperti PROPER. Dengan demikian, artikel ini akan menganalisis kebijakan taksonomi hijau sebagai kebijakan pintar/smart policy untuk mencegah kerusakan lingkungan.
A Census of the 32 Ori Association with Gaia*
Authors: Luhman K. L.
Published: September 2022

I have used high-precision photometry and astrometry from the third data release of Gaia (DR3) to identify candidate members of the 32 Ori association. Spectral types and radial velocities have been measured for subsets of the candidates using new and archival spectra. For the candidates that have radial velocity measurements, I have used UVW velocities to further constrain their membership, arriving at a final catalog of 169 candidates. I estimate that the completeness of the survey is ∼90% for spectral types of ≲M7 (≳0.06 M
⊙). The histogram of spectral types for the 32 Ori candidates exhibits a maximum at M5 (∼0.15 M
⊙), resembling the distributions measured for other young clusters and associations in the solar neighborhood. The available UVW velocities indicate that the association is expanding, but they do not produce a well-defined kinematic age. Based on their sequences of low-mass stars in color–magnitude diagrams, the 32 Ori association and Upper Centaurus-Lupus/Lower Centaurus-Crux (UCL/LCC) are coeval to within ±1.2 Myr, and they are younger than the β Pic moving group by ∼3 Myr, which agrees with results from previous analysis based on the second data release of Gaia. Finally, I have used mid-IR photometry from the Wide-field Infrared Survey Explorer to check for excess emission from circumstellar disks among the 32 Ori candidates. Disks are detected for 18 candidates, half of which are reported for the first time in this work. The fraction of candidates at ≤M6 that have full, transitional, or evolved disks is

We quantified the effects of stellar feedback in RCW 49 by determining the physical conditions in different regions using the [C ii] 158 μm and [O i] 63 μm observations from SOFIA, the 12CO (3–2) observations from APEX, and the H2 line observations from Spitzer telescopes. Large maps of RCW 49 were observed with the SOFIA and APEX telescopes, while the Spitzer observations were only available toward three small areas. From our qualitative analysis, we found that the H2 0–0 S(2) emission line probes denser gas compared to the H2 0–0 S(1) line. In four regions (“northern cloud,” “pillar,” “ridge,” and “shell”), we compared our observations with the updated PDR Toolbox models and derived the integrated far-ultraviolet flux between 6 and 13.6 eV (G
0), H nucleus density (n), temperatures, and pressures. We found the ridge to have the highest G
0 (2.4 × 103 Habing units), while the northern cloud has the lowest G
0 (5 × 102 Habing units). This is a direct consequence of the location of these regions with respect to the Wd2 cluster. The ridge also has a high density (6.4 × 103 cm−3), which is consistent with its ongoing star formation. Among the Spitzer positions, we found the one closest to the Wd2 cluster to be the densest, suggesting an early phase of star formation. Furthermore, the Spitzer position that overlaps with the shell was found to have the highest G
0, and we expect this to be a result of its proximity to an O9V star.
