Authors: ВОЛЧКОВ В.П. , САННИКОВ В.Г.
Published: July 2021

Рассмотрен синтез банка цифровых фильтровдля частотно-временного анализа дискретных комплексных сигналов, заданных на конечном интервале. Для этой цели предлагается использовать специальный инструментарий - комплексный сигнальный базис Вейля-Гейзенберга. Показано, что такой подход позволяет гибко настраивать частотно-временные характеристики цифровых фильтров в соответствии с желаемым эталоном и ведет к многоскоростной многоканальной фильтровой процедуре, допускающей быструю вычислительную реализацию. Получены конечные формулы, описывающие банк фильтров, и приводится анализ его вычислительной эффективности.

The synthesis of a bank of digital filters for the frequency-time analysis of complex discrete signals defined on a finite interval is considered. For this purpose, it is proposed to use a special tool -kit - a complex signal basis of Weyl-Heisenberg. It is shown that this approach allows flexible adjustment of the time-frequency characteristics of digital filters in accordance with the desired standard and leads to a multi-speed multi-channel filter procedure that allows fast computational implementation. The final formulas describing the filter bank are obtained, and an analysis of its computational efficiency is presented.

FREQUENCY SYNTHESIS WITH DIGITAL-TO-ANALOG COMPENSATION OF FRACTIONAL NOISE IN THE PLL SYSTEM
Authors: КОЗЛОВ В.И.
Published: July 2021

Идея цифроаналоговой компенсации помех дробности состоит в том, что и компенсирующий, и управляющий частотой генератора в петле фазовой автоподстройки частоты (ФАПЧ) сигналы формируются одновременно и совместно в цифровом виде и лишь на последнем этапе трансформируются в аналоговый сигнал, чем достигается высокая спектральная чистота сигнала, зависящая исключительно от точности ЦАП. Приведен расчет спектра сигнала. Проведено сравнение с существующими широко применяемыми DDS и Fractional-N PLL синтезаторами.

The idea of digital-to-analog fractional noise cancellation is to construct a phase detector circuit in such a way that the compensating and main frequency control phase-locked loop (PLL) signals are both generated together and simultaneously in digital form and only at the last stage are transformed into an analog signal. Calculation of the signal spectrum is given. Comparison is made with the existing widely used DDS and Fractional-N PLL synthesizers.

Рассмотрена задача математического моделирования передачи энергии в автономной робототехнической роевой системе. Существующие математические модели не учитывают особенности беспроводной передачи энергии между агентами роя, действующими как совместно с роем, так и отдельно от него. Представлен обзор и сравнительный анализ современных исследований в данной области. Показана необходимость разработки модели исходя из энергообмена между агентами. Рассмотрена математическая модель роевой робототехнической системы, учитывающая энергетические характеристики единичного агента,группы роботов и роя в целом. Продемонстрировано успешное применение данной модели на примере гомогенных мобильных роботов МАРС в совокупности с системой беспроводной передачи энергии БСПЭ-3.

In this paper the energy transfer mathematical model in terms of autonomous swarm robotic system is considered. Existing mathematical models do not account for wireless power transfer peculiarities among swarm agents, acting as together with the whole swarm, as separately from it. This paper presents review and comparative analysis of recent research in this domain. The paper shows the relevance of development of such mathematical model, that would cover energy exchange among agents. The developed mathematical model accounts for energy characteristics of an individual agent, of a robot group and of a whole swarm, as well the possibility, that the task may be executed by one or several agents. The proposed mathematical framework allows calculating time and energy, required to complete the task, particularly, the energy, transmitted between the agents with respect to the power losses of the transmission channel. The mathematical model was successfully tested within a swarm of mobile MARS robots, combined with wireless energy transfer system WETS-3.

Подбор ИК позволяет улучшить показатели качества оценивания импульсных характеристик методом регуляризации при наличии памяти в каналах связи.

The problem of estimating the impulse response of the communication channel with memory when receiving OFDM signals using the "reception in general with element-wise decision-making" (RGEWDM) algorithm by the regularization method is considered. Variants of new structures of a stream of OFDM symbols are proposed with the exclusion of guard intervals and the inclusion of a test combination (TC) in the structure of the transmitted signal in the presence of memory in the communication channels; for rapidly changing channels frequent insertion of TC is proposed. The selection of TCs allows improving the quality indicators of impulse response estimation by the regularization method in the presence of memory in communication channels.

apoyo diplomático de Panamá a la Argentina en torno a la Cuestión Malvinas durante el período torrijista (1969-1983).
Authors: Rossi Pizzi Bruno
Published: July 2021

El objeto del presente artículo es escudriñar la postura de la República de Panamá en torno a la Cuestión Malvinas durante el período del torrijismo (1969-1983), a partir del prisma de la teoría de la autonomía. Luego de haber descrito en líneas generales la política exterior del régimen gobernante, analizamos, en primer lugar, la firma de la declaración Perón-Torrijos de enero de 1974—los intereses que la suscitaron, sus fundamentos y su sostenimiento en el tiempo. Seguidamente, hacemos especial hincapié en el accionar de la diplomacia panameña ante el conflicto armado de 1982, máxime teniendo en cuenta que, en aquel año, Panamá era el único país latinoamericano en ocupar un asiento en el Consejo de Seguridad de las Naciones Unidas. A modo de conclusión, sostenemos que el apoyo panameño a la Argentina en torno a la Cuestión Malvinas ha sido una manifestación de su vocación autonomista en el período estudiado.
racismo como ideología y su negación en nuestras sociedades
Authors: Quintero Corrales Hilda Beatriz , Murillo Moreno Alexander
Published: July 2021

Fuera de todo concepto, explicar el fenómeno del racismo hacia comunidades afro-descendientes e indígenas, centrado en la segregación es una empresa compleja; hablar de racismo es expresarlo en relación al color y la etnia, sin aislar la existencia del ser humano; ello conlleva a un sinnúmero de elementos que configuran la discriminación hacia estos grupos sociales justificada por una cuestión de creencias e ideologías arraigadas, las cuales garantizan un sistema de opresión, desigualdad y subyugación. En Colombia, ideas racistas son promovidas desde narrativas públicas lideradas por referentes y políticos de la élite nacional cuyos juicios dan mayor sustento a la segregación. Los estereotipos han modificado costumbres y creencias de los segregados alterando su idiosincrasia; algunos cansados del asedio eligen parejas blancas para que sus descendientes tengan piel más clara, alejándolos de la segregación y facilitando el acceso a mayores oportunidades, aunque en el proceso tienden a perder su identidad. El racismo es una práctica disimulada, sutil e hipócrita. Los derechos de las minorías y su protección están en el imaginario, pues el Estado no está en condiciones, ni tiene la voluntad para hacer efectivo su reconocimiento legal; la lucha para defenderlos debe darse de forma más abierta, traspasando fronteras geopolíticas.
Hacia el escenario nuclear en Oriente Medio:
Authors: Sánchez Piccat Alejo
Published: July 2021

El programa nuclear iraní y la amenaza que este generó en Oriente Medio a partir del 2003, impulsó a que los Estados más importantes en la región se embarcaran en una serie de estrategias para mitigar la posesión y desarrollo de armas nucleares por parte de Irán. En el presente trabajo de investigación se analizan y comparan las capacidades nucleares de Israel, Arabia Saudita y Turquía, para poder definir su estatus disuasorio frente a la República Islámica de Irán entre 2003 y 2018. Adoptando como principales variables las capacidades económicas, los recursos empleados en un programa nuclear y las limitaciones y apoyos políticos a los mismos, se concluye que la amenaza nuclear iraní genera que los 3 Estados se involucran en una carrera armamentística frente al nuevo escenario disuasorio.

¿Por qué no vemos a los afroargentinos en C.A.B.A.?
Authors: Parisio Ángeles Maia
Published: July 2021

El objetivo del presente trabajo consiste en desarrollar algunos de los mecanismos mediante los cuales ha tenido tanta eficacia el fenómeno del blanqueamiento racial en la Argentina. Para ello, en primer lugar, se introducirán las ideas principales de la teoría decolonial, con la finalidad de comprender la matriz eurocentrista del nacimiento de los Estados-Nación latinoamericanos en general, y del argentino en particular. En segundo lugar, se presentarán las construcciones de la historia nacional que intentan explicar la presunta “desaparición” de esta población. Asimismo, se expondrá una interpretación histórica que ofrece la posibilidad de contemplar una versión distinta de los hechos. En tercer lugar, se abordarán las construcciones de las categorías raciales que se utilizan actualmente en la Ciudad de Buenos Aires, y su conexión con la historia de dichas categorías. Para concluir, se presentarán algunas reflexiones sobre los mecanismos mediante los cuales esta población se torna invisible tanto a nivel macro-social como en la mirada de la vida cotidiana de los argentinos.
Carl Schmitt y el realismo político
Authors: Galli Carlo , Vendramin Bruno
Published: July 2021

En este artículo el autor defiende una particular posición de realismo político, al cual denomina “crítico”, distanciándose de la acepción convencional del concepto realismo. Seguidamente, analiza qué entendió Carl Schmitt por realismo, cuál fue su concepción de política y hasta dónde llega la capacidad crítica de su pensamiento. Finalmente, concluye que el realismo de Schmitt no es lo suficientemente autocrítico por no cuestionar sus propias categorías, por lo que su pensamiento vale como ejemplo concreto, en un contexto histórico determinado, que invita a reflexionar sobre el realismo más allá de Schmitt.

Authors: Pugliese Pablo , Griffini Bautista
Published: July 2021

En los últimos años, los crecientes desarrollos en el campo de la Inteligencia Artificial se han convertido en uno de los principales motores de innovación tecnológica. Sin embargo, su aplicación en diversos tipos de sistemas de armas comienza a poner de relieve las problemáticas fundamentales de su uso en los escenarios de conflicto tanto actuales como futuros. A partir de un análisis profundo, este trabajo estudia una serie de puntos sobre los cuales la utilización de los Sistemas de Armas Autónomas Letales puede generar controversia. Partiendo desde la tecnología como factor disruptivo en el campo de batalla, pasando por los problemas conceptuales en la definición de la Inteligencia Artificial, recorriendo los dilemas éticos y jurídicos en el uso de estos sistemas, arribando hasta las implicancias de su utilización en el escenario internacional, llegamos a la conclusión de que el uso de estos sistemas traería consigo un proceso de “deshumanización de la guerra”.

Efectos de Choques No Anticipados en el Ingreso sobre el Consumo en México, 2000-2016
Authors: Llamosas-Rosas Irving , Rangel González Erick
Published: July 2021

Se analizan los cambios en el consumo de los hogares mexicanos ante cambios no esperados en los ingresos, tanto permanentes como transitorios, durante el periodo 2000-2016 siguiendo la metodología desarrollada por Blundell et al. (2008), la cual permite evaluar qué hipótesis sobre la respuesta del consumo es más acorde con la evidencia empírica en México: de ingreso permanente, de mercados completos, o de aseguramiento parcial. Los resultados sugieren la presencia de aseguramiento parcial en el consumo ante choques permanentes en el ingreso a nivel nacional, aunque también son consistentes con la hipótesis de ingreso permanente. Sin embargo, se encuentran diferencias entre regiones al replicar el mismo análisis. En referencia a los choques temporales, el coeficiente del efecto del choque al ingreso sobre el consumo no resulta estadísticamente significativo, a nivel nacional ni regional, lo que sugiere un suavizamiento del consumo por parte de los hogares ante cambios temporales en su ingreso.
A Comprehensive Three-Phase Step Voltage Regulator Model with Efficient Implementation in the Z-Bus Power Flow
Authors: Pompodakis Evangelos , Kryonidis Georgios C. , Alexiadis Minas
Published: July 2021

This
paper presents a comprehensive three-bus equivalent circuit model of
three-phase step voltage regulators. The proposed model can be efficiently
integrated in the Z-bus power flow method and can accurately simulate any
configuration of step voltage regulators. In contrast to the conventional step
voltage regulator models that include the tap variables inside the YBUS
matrix of the network, the proposed model simulates them in the form of current
sources, outside the YBUS matrix. As a result, the re-factorization
of the YBUS matrix is avoided after every tap change reducing
significantly the computational burden of the power flow. Furthermore, possible
convergence issues caused by the low impedance of step voltage regulators are
addressed by introducing fictitious impedances, without, however, affecting the
accuracy of the model. The results of the proposed step voltage regulator model
are compared against well-known commercial softwares such as Simulink and
OpenDSS using the IEEE 4-Bus and an 8-Bus network. According to the
simulations, the proposed model outputs almost identical results with Simulink
and OpenDSS confirming its high accuracy. Furthermore, the proposed 3-bus
equivalent model is compared against a recently published conventional step
voltage regulator model in the IEEE 8500-Node test feeder. Simulation results
indicate that the proposed step voltage regulator model produces as accurate
results as the conventional one, while its computation time is significantly
lower. More specifically, in the large IEEE 8500-node network consisting of
four SVRs, the proposed model can reduce the computation time of power flow
around one minute for every tap variation. Therefore, the proposed step voltage
regulator model can constitute an efficient simulation tool in applications
where subsequent tap variations are required.

Published: July 2021

The paper describes an online deep learning algorithm for the adaptive modulation and coding in 5G Massive MIMO. The algorithm is based on a fully connected neural network, which is initially trained on the output of the traditional algorithm and then is incrementally retrained by the service feedback of its output. We show the advantage of our solution over the state-of-the-art Q-Learning approach. We provide system-level simulation results to support this conclusion in various scenarios with different channel characteristics and different user speeds. Compared with traditional OLLA our algorithm shows 10% to 20% improvement of user throughput in full buffer case.

The Ultra-Large-Scale Software (ULSS) systems development challenges today’s software management and development approaches. Northrop et al. (2006) revealed three broad areas of challenges [1]. To deal with those challenges, they propose an interdisciplinary portfolio of research. In particular, we address the design and evolution challenge by focusing on the design area of research. In order to regulate the ULSS systems, the traditional software engineering tools face challenges as they are top-down so they deal with each domain model separately. To address the domain diversity like in the smart city systems, we propose the Framework for Agile Regulated Ultra Large Scale Software System (FARUL3S) to look at the ULSS system from bottom-up. The FARUL3S is a user-centered solution that aims at combining the complex adaptive system, the financial economics as well as the engineering systems design. Our contribution aims to regulate and constrain the ULSS systems by using architectural agreements and other rules. In this paper, we provide a detailed description of the FARUL3S steps. Our Framework generates a system Design Rule Hierarchy (DRH) so it can be used to constrain the entire system design. In the future, we will provide an illustration of the FARUL3S adoption on the management and design of different smart city services to ensure the efficiency of our solution.
Data-Driven Single Image Deraining: A Comprehensive Review and New Perspectives
Authors: Zhang Zhao , Wei Yanyan , Zhang Haijun , Yang Yi , Yan Shuicheng , Wang Meng
Published: July 2021

Single Image Deraining task aims at recovering the rain-free background from an image degraded by rain streaks and rain accumulation. For the powerful fitting ability of deep neural networks and massive training data, data-driven deep SID methods obtained significant improvement over traditional ones. Current SID methods usually focus on improving the deraining performance by proposing different kinds of deraining networks, while neglecting the interpretation of the solving process. As a result, the generalization ability may still be limited in real-world scenarios, and the deraining results also cannot effectively improve the performance of subsequent high-level tasks (e.g., object detection). To explore these issues, we in this paper re-examine the three important factors (i.e., data, rain model and network architecture) for the SID problem, and specifically analyze them by proposing new and more reasonable criteria (i.e., general vs. specific,synthetical vs. mathematical, black-box vs. white-box). We also study the relationship of the three factors from a new perspective of data, and reveal two different solving paradigms (explicit vs. implicit) for the SID task. We further discuss the current mainstream data-driven SID methods from five aspects, i.e., training strategy, network pipeline, domain knowledge, data preprocessing, and objective function, and some useful conclusions are summarized by statistics. Besides, we profoundly studied one of the three factors, i.e., data, and measured the performance of current methods on different datasets through extensive experiments to reveal the effectiveness of SID data. Finally, with the comprehensive review and in-depth analysis, we draw some valuable conclusions and suggestions for future research.

Automated Waste Segregation using Convolution Neural Network
Authors: Ravishankar Anagha , Murthy Anvita , Sharma Manas , Chitra R K
Published: July 2021

The key to efficient waste management is to ensure segregation of
waste and resource recovery. Waste is usually segregated on the basis of
whether it is biodegradable or non biodegradable. A major challenge with
respect to this is that waste is not segregated before collection and is thrown
into dustbins nonetheless. These end up as huge piles of waste in dump yards,
which needs to be segregated.
Waste segregation is currently being done manually by
the Municipal Corporation. These results in unsanitary working conditions for
the people who need to perform this task. Despite being provided with the
necessary equipment, they run the risk of catching infections from the waste
they work with. Automation of this process will be beneficial for the people
who work on this, by reducing health hazards.
Towards the Optimal Antenna-Based Wireless Sensing Strategy: An Ice Sensing Case Study
Authors: Wagih Mahmoud , Shi Junjie
Published: July 2021

Remote ice detection has emerged as an application of Radio Frequency (RF) sensors. While antenna-based “RFID” sensing can detect various measurands, antenna-based sensors are not currently designed based on a systematic methodology, and in most cases may have a low sensitivity requiring specialist hardware or broadband interrogation signals, incompatible with spectrum regulations. Here, we develop a systematic methodology for designing an antenna-based sensor, applicable to measurands inducing a dielectric change in the near-field of the antenna. The proposed methodology is applied to designing printable antennas as highly-sensitive sensors for detecting and measuring the thickness of ice, demonstrating best-in-class sensory response compared to more complex antenna designs. Antenna design is investigated systematically for wireless interrogation in the 2.4 GHz band, where it is found that a loop antenna outperforms a dipole owing to its more distributed capacitance. The antenna’s realized gain was identified as the optimum parameter-under-test, with “positive” sensing proposed as a method of improving linearity and immunity to interference. The developed loop antenna sensor exhibits resilience to interference and applicability to different real-world deployment environments, demonstrated through over 80% average ice thickness measurement accuracy and at least 5 dB real-time sensitivity to ice deposition.
A High-Level Approach for Energy Efficiency Improvement of FPGAs by Voltage Trimming
Authors: Safarpour Mehdi , Xun Lei , Merrett Geoff V. , Silven Olli
Published: July 2021

This paper proposes a solution that makes voltage scaling possible by simply using HLS tools provided by vendor to improve energy efficiency of FPGAs by 2x. Chip manufacturers define voltage margins on top of the “best-case” operational voltage of their chips to ensure reliable worst case functionality. The margins guarantee correct-ness of operation, but at the cost of performance and power efficiency. Violating the margins is tempting to save energy, but might lead to timing errors. This paper proposes an algorithmic solution that enables reliable removal of the margins by detecting errors on-the-fly. In contrast to previous approaches that require special hardware to detect timing errors, the proposed method is fully implementable using High Level Synthesis tools without reliance on additional hardware. The approach is demonstrated using a32×32matrix-matrix multiplication and a simple multi-layer neural network implemented on two Xilinx ZC702Field-Programmable-Gate-Array (FPGA) System-on-Chip (SoC)platforms, showcasing its utility in detecting errors that may originate from different sources of logic circuity, clock tree and memory. Results show that the energy dissipation is halved, while the implementation is clocked at 2.5x faster than specified by the design tool of the vendor.

Asbabun Nuzul Surah Al-An’am Ayat 108
Authors: Esa Prasastia A Muhammad
Published: July 2021

The Koran is the mother book of Muslims which is always interesting to be discussed because various aspects of its contents can become a hot discourse. This is due to the breadth of discussion that can be drawn from it. The purpose of this study is to examine the asbabun nuzul from Surah Al-An'am verse 108. This study uses a library research method that refers to available sources both online and offline such as: scientific journals, books and news sourced from sources Trusted. This data was obtained through triangulation techniques. The data were analyzed and then conclusions were drawn. The results of this study are in the interpretation of surah al-An'am verse 108 of which it is forbidden to curse the idols of the polytheists because it is possible that the polytheists will retaliate even more badly, the curse will be addressed to Allah swt. Then from several commentators such as Jalalain's interpretation, Ibn Kathir's tafseer, and al-Misbah's interpretation also gave an explanation that education is important for every human being. And in the interpretation of the verse, the commentators when explaining the sura al-An'am verse 108 are more conspicuous in terms of preventive action, namely preventing disputes between fellow social groups.
Bilangan 5:11–31: Ritual Sotah sebagai Terobosan Budaya di Timur Tengah Kuno
Authors: Yong Steven
Published: July 2021

Numbers 5:11–31: Sotah as a Cultural Breakthrough in the Ancient Near East. Numbers 5:11–31 could be interpreted as a kind of sexism and repression to women. In the Mishnaic tradition, the passages indeed are being understood and developed in such a manner. From tractate Sotah in Mishnah, the suspected adulterous wife indeed is ashamed and treated as a prostitute. This article seeks to present another perspective on the passage. This article uses the sociological study method to identify the sociological problems alleged against the passage based on the explanation of the Sotah tractate in the Mishnah. Afterward, the inferior position of women in the ancient Near East will be explained as a cultural context to understand the passage better. Finally, considering this cultural context and comparing the Sotah ritual with the common rituals in the ancient Near East, this article argues that Numbers 5:11–31 could be seen as a cultural breakthrough to protect women, which are considered marginalized.
Negation and Pronoun Position as a way of investigating verb movement and the emergence of do support during Early Modern English
Authors: Abugharsa Aisha Fathi
Published: July 2021

This paper presents an analysis of the rise of do support and the gradual loss of verb movement during the period of Early Modern English. The analysis focuses on studying the structures in which do support was first used as an alternative to verb raising to I. It takes into consideration the analysis of the relationship between the position of the negation marker not in negative interrogative structures and the position of the subject and the object pronouns in these structures. The analysed structures are negative interrogatives taken from Shakespeare’s works in the period of Early Modern English. The results of the data analysis show that in most cases, there is do support when the subject pronouns are above negation, while there is no do support when object pronouns appear above negation. This suggests that do was first inserted here to avoid object raising with the verb to I or to C to avoid putting object and subject pronouns in subsequent positions.

Actual level of Bronchial Asthma (BA) control is not perfect now, despite of modern effective treatment and increase in quantity of their consumption. It testifies that in addition to correction of volume of pharmacological loading for BA patients the account of negative influence of external factors (allergens, an infection) and correction of the comorbidities which potentially worsening an asthma condition is necessary. Besides, there are different ways for an estimation of a condition of BA control: based as on objective datas (ventilation parameters, sputum eosinophilia, tests for airway hyperreactivity) and the subjective data (the various questionnaires filled with patients) are used. The analysis of the reasons for full BA control absence in the majority of patients and search of an optimum combination for an estimation of a condition of patients with BA is an actual problem of modern medicine.
