Verdades inconvenientes: búsqueda de un intelectual público por la verdad, la justicia y el poder
Authors:   Cámara de Representantes de Filipinas, Bello Walden
Published: April 2021

La sociología pública cuestiona las sabidurías convenidas y avanza el análisis agudo y singular. También enfrenta a concepciones convencionales que se incrustan en el sentido común y que representan intereses o la lógica de la fuerza. Para trascender al sentido común, como el de la ortodoxia neoliberal, es inevitable la formación de un movimiento social. Y, para retar a la sabiduría convencional, se requiere develar la verdad mediante el uso de métodos poco ortodoxos, aunque esto implique, en muchas ocasiones, enfrentarse con agencias poderosas y depositarias de secretos. Independientemente de que las verdades estén ocultas y en manos del poderoso o el débil, rescatar la verdad engendra hostilidad permanente, así lo he experimentado con mi investigación sobre los asesinatos consumados por el Partido Comunista de Filipinas. El conflicto inherente entre la verdad y el poder nunca desaparece.
Acumulación por desposesión dentro de la lógica rentista en Brasil
Authors:   Universidade Estadual de Londrina, Tomiasi Paulino Eliane
Published: April 2021

Partiendo de marcos conceptuales asociados a la acumulación por desposesión, el artículo se posiciona en el caso brasileño, país que en términos proporcionales representa los mayores índices de concentración del suelo en el mundo e incomparable desigualdad social. La monopolización del suelo es, al mismo tiempo, producto y productora de relaciones de poder asimétricas, añadiendo un elemento que complica la situación: la ausencia de distinción de clases en el sentido clásico, una vez que legalmente los propietarios rurales tienen negocios urbanos y los capitalistas son propietarios de grandes fracciones de tierras en el país. La apropiación de la tierra se dedica menos a fines productivos y más a especulativos, lo cual alude a que en el país existe una modalidad dominante del capitalismo denominado «rentista», dentro del cual los despojos ambiental y territorial son estructurados. Su legitimación reposa en la supuesta racionalidad virtuosa de la agricultura a escala que justificaría la manutención del monopolio de la tierra. Se solidifica una alianza tierra-capital, cuyo esfuerzo de ocultar la ineficiencia de la gran propiedad ha sido exitoso, pues la reforma agraria ha desaparecido de la agenda política, al mismo tiempo que van destruyéndose los viejos marcos constitucionales relativos a los derechos ambientales y territoriales a quienes tienen derecho. Lejos de ser ineficientes, como hacen creer los que necesitan de argumentos productivistas para seguir concentrando la tierra, riqueza y poder, los campesinos son más eficientes y se justifican los esfuerzos analíticos que revelan a la sociedad esa paradoja, como forma de confrontar el pacto oligárquico que, en nombre del desarrollo, requiere modalidades de despojo ambiental y territorial contrarias a la soberanía y autodeterminación nacional.

Wi-Fi services provided by institutions are critical factors helping students in their learning process, especially during the COVID-19 pandemic. However, studies concerning Wi-Fi performance on students’ satisfaction in Polytechnics Malaysia are limited. Hence, this study aims to investigate the influence of Wi-Fi service quality on students’ satisfaction, particularly in the Politeknik Tuanku Syed Sirajuddin (PTSS) context. Specifically, this study examines the influence of reliability, tangibility, responsiveness, assurance, and empathy on students’ satisfaction towards Wi-Fi performance. Quantitative and single cross-sectional studies were employed. A total of 260 students responded to the survey questionnaires. Multiple regression analysis results revealed that reliability, tangibility, responsiveness, assurance, and empathy influence students’ satisfaction. It shows that improving reliability, tangibility, responsiveness, assurance, and empathy is very important to increase students’ satisfaction. The results also indicated that responsiveness is the primary factor influencing students’ satisfaction. This study is hoped to enlighten the polytechnic management to improve Wi-Fi performance for the students.

AUTOMATED CONTROL OF THE SOFTWARE PROTOTYPE CODE REVIEW BASED ON THE QUESTION-ANSWERING PROTOCOLS FOR REQUIREMENT ANALYSIS
Authors:   Ulyanovsk State Technical University, Lapshov Iurii A.
Published: April 2021

The paper describes the architecture of software tools for automating the management of code review of software prototypes of design solutions that allow to obtain such effects as ensuring interactive interaction between the designer and an expert performing code review, as well as reducing the expert’s time spent on commenting the code by selecting a comment from the list prepared in advance for each requirement from the requirements obtained during the analysis. The tools being developed consist of three main parts. The first part presents requirements in a question-and-answer format including standard comments to be inserted into the prototype code in case of non-compliance with these requirements. The second one is a relational database, which is designed to store the source codes of prototypes aimed at inspection and passed it with expert comments. The third one is a Web-application that allows the designer to send prototype codes for review and see the results of the inspection, and an expert to provide viewing and editing of the prototype source code with the insertion of both standard, pre-prepared comments, and written in free form.

Authors:   Bauman Moscow State Technical University, Kozov Aleksei V.
Published: April 2021

High adaptability is an important requirement for the control system over a group of mobile robots operating in a nondeterministic changing environment. The group control system must ensure that the group task is completed when the structure of the group or the environment changes. Such adaptability can be achieved through dynamic reconfiguration of the control system. The article discusses the mathematical models of a dynamically reconfigurable system from the standpoint of computer-aided design. A review of mathematical models of variable structure system, reconfigurable control systems and their design methods is presented. The paper deals with set-theoretic, analytical, discrete-event models of variable structure systems and methodologies of designing reconfigurable systems. It is shown that the existing design methods do not fully provide the required adaptability of designed group control system. The paper compares the group control system and the reconfigurable multiprocessor computing system and shows how to increase adaptability and autonomy of designed control system using principles of reconfigurable computing systems designing.

The use of noise-tolerant coding in modern communication systems remains the only means of increasing the efficient energy of such systems. This parameter tends to increase in conditions when the receiver of the communication system is able to correct errors of a large multiplicity. At the same time, the existing experience of using various methods for decoding the received data to achieve such a goal in the format of algebraic or iterative procedures does not give a noticeable effect and leads to a large time cost and an exponential increase in the complexity of implementing the decoder processor. The reason for this situation is the passive position of the receiver, which, when processing each code vector, remains a fixator of the picture that occurred in the communication channel and, in general, by compiling a system of linear equations and then solving it, tries to identify the error vector. Some exceptions are permutation decoding systems, which, by selecting and using reliable characters from the number received at the reception, simulate the operation of their transmitter and compare the received (almost error-free) result of such encoding with the received combination [1, 2]. With the growing influence of destructive factors, such methods are ineffective. A natural question arises: are modern solutions in neural network technologies capable of improving the characteristics of code vector recognition systems in order to obtain acceptable machine time costs in order to achieve an increase in the energy characteristics of communication systems.
METHODOLOGICAL SUPPORT FOR THE DIVIDING OF FACTORIAL SETS SUBSTITUTIONS
Authors:   Sarov Institute of Physics and Technology, Martynova Inna A.
Published: April 2021

The substitution and permutation functions are the main functions of information cryptographic systems that provide diffusion and mixing of information. It is required to analyze these cryptographic primitives while creating new algorithms for data transformation using such functions. A new scale of notation has been proposed for performing such analysis. This is the factorial sets statistical series notation scale. This scale of notation helps to index the factorial sets statistical series elements and establish a one-to-one correspondence between the number and a specific type of substitution. The use of this system provides a way to find new characteristics and properties of substitutions. Since substitutions of the factorial sets form a cyclic group, the operation on elements of this group can be determined. In the general case, the operation used is a multiplication of substitutions, but this paper suggests another operation for group determination. The article presents a capability for dividing the factorial sets substitutions. Two methods for implementing the substitution division operations are proposed such as a method of successive transition and a method of group transition, which are implemented through non commutative operation of multiplying on inverted substitutions.

Published: April 2021

This article presents and solves the problem of evaluating the quality of the Cetlin method, which classifies the sequence of RR-intervals by the recordings of ECG signals from MIT-BIH, which have labels on R-peaks. To solve this problem, author proposes new quality metrics and describes developed algorithms for calculating them in real time with taking into account segmentation errors. Author analyzes the influence of the accuracy of the segmentation procedure for extracting the positions of R-peaks from ECG signal on the proposed quality metrics. Paper compares the quality of the Cetlin method and other existing algorithms for arrhythmia detection that analyze the duration of RR-intervals in accordance with a set of rules in real time. Article reveals advantages and limitations of the method. Paper shows that the method successfully detects SVEB and VEB arrhythmias. but has inertia, that leads to false positives, and is immune to morphological abnormalities that do not change the duration of RR-intervals. Author analyzes the influence of parameters of the Cetlin method on its quality according to the proposed metrics. Paper describes the procedure for searching the best parameters configuration. In conclusion, author reveals that there is no the only configuration, that achieves the best quality for each signal from MIT-BIH.
Health information-seeking behaviors among high-perceived cancer risk individuals who experienced hearing loss: An exploratory study
Authors: Hinson-Enslin Amanda M. , Massey-Stokes Marilyn , Kushalnagar Poorna
Published: April 2021

Introduction: Few studies identify which health information (HI) people trust and use, and some studies have focused on health information-seeking behaviors (HISB) of individuals with varying perceived cancer risk (PCR). However, most HISB and PCR studies focus on mainstream populations with typical hearing ability. The purpose of this study was to examine the association between HISB and high PCR (HPCR) among English speakers who experienced hearing loss.
Methods: Data from the English version of the 2013 Health Information National Trends Survey (HINTS) 4 Cycle 3 were analyzed. Frequencies were calculated from HINTS 4 Cycle 3 survey questions. Correlation analysis was used to examine relationships between HPCR status and the various trusted HI sources. A significant correlation coefficient (Pearson’s r) was p set at .05.
Results: Of the 229 participants self-identifying as experiencing hearing loss, 46 identified as having HPCR. Moreover, over 95% of HCPR participants endorsed speaking English well. In their latest HI search, participants reported they first accessed HI from the internet (28.3%) yet also indicated their most trusted HI source were doctors (97.8%). Pearson’s r indicated no significant relationship between PCR status of participants and degree of trust in HI sources (p < .05).
Conclusions: Health professionals should deliver clear and relevant health messages and materials that are understood by individuals who experience hearing loss, including those with HPCR. For individuals who experience hearing loss, health education and communication specialists need to consider alternate communication methods such as writing, speech recognition apps, or captions to support health communication.

Strain relaxation in semiconductor wafer bonding
Authors: Tanabe Katsuaki
Published: April 2021

The strain relaxation process in wafer-bonded semiconductor heterostructures is numerically investigated, in contrast to those formed by epitaxial growth. A kinetic model of strain relaxation in semiconductor layers is re-established for highly lattice-mismatched heterostructures. Numerical simulations are then performed by using the model to analyze the time evolution of the strain, the strain rate, and the misfit dislocation density. The calculation results present a slow strain relaxation behavior in the lattice-mismatched heterostructures wafer-bonded at lower temperatures than those for epitaxial growth, to suppress the thermodynamically preferred dislocation generation by sustaining the material system at a metastable state. The time constant of strain relaxation in a typical range of wafer bonding temperatures, normalized by the melting temperature, of 0.2–0.4 is found to be 3 × 105–2 × 1021 s for a lattice mismatch of 0.04. This relaxation time contrasts with 14 s for the case of heteroepitaxy at a typical normalized temperature of 0.6, thus evidencing the nonequilibrium crystalline stability in wafer bonding.

El rescate financiero de los gobiernos estatales por el gobierno federal: Comparación de los casos de Estados Unidos, Brasil y México
Authors: Rafael Gamboa González
Published: April 2021

Las transferencias del Gobierno Federal (GF) para rescatar a un Gobierno Estatal (GE), han sido analizadas conforme al llamado "juego de la gallina": ( En inglés se conoce como game of chicken.) mientras que el GE acumula cantidades crecientes de deuda, el GF se mantiene firme en su compromiso de no responder por adeudos del GE. Describir el problema de esta forma, sin embargo, ignora la secuencia de eventos en la cual el GE primero selecciona su deuda y, posteriormente, cuando el GE está por declarar la moratoria de pagos, se pone a prueba la firmeza del compromiso del GF de no rescatar a un GE. La acción tomada por el GE depende de lo que crea que vaya a hacer el GF. Por lo tanto, la credibilidad del GF es crucial para conocer el desenlace. Es decir, los incentivos que tenga el GF para rescatar al GE que se encuentra en dificultades. En los Estados Unidos, el GF se ganó la reputación de honrar su compromiso de no rescatar GE durante el siglo pasado, mientras que en Brasil y recientemente en México los rescates han sido una práctica más habitual. Las diferencias fundamentales en los Estados Unidos por un lado, y Brasil y México por el otro, son las siguientes: en los Estados Unidos el GF tenía pocas y en exceso utilizadas fuentes de tributación, pocos estados eran incapaces de cubrir sus pagos y los acreedores eran extranjeros; en Brasil durante los últimos 15 años y en México en 1995 se cuenta con disponibilidad de fuentes de tributación amplias por parte del GF a la vez que los GE cuentan con bases menos flexibles, las regiones endeudadas tienen un fuerte impacto en la economía nacional y los acreedores son por lo general agentes nacionales importantes. En presencia de instituciones como las existentes en Brasil y México, el establecimiento de límites al endeudamiento estatal podría imponer disciplina fiscal entre los estados de un país federal y prevenir rescates al GE.
El efecto sobre el tipo de cambio y las tasas de interés de las intervenciones en el mercado cambiario y del proceso de esterilización
Authors: Werner Alejandro
Published: April 2021

Este trabajo estudia el impacto sobre el tipo de cambio y las tasas de interés tanto de las intervenciones del Banco de México realizadas en el mercado cambiario a través del mecanismo de opciones, así como de la política de esterilización que ha seguido el Instituto Central. De estos ejercicios se concluye que hasta el momento, no se ha detectado un efecto importante de las intervenciones en el mercado cambiario y de su esterilización subsecuente en la determinación del tipo de cambio y las tasas de interés. Sin embargo, los resultados de las estimaciones efectuadas indican que durante los últimos meses de 1997, el efecto de las operaciones de esterilización sobre las tasas de interés fue estadísticamente significativo pero de una magnitud muy pequeña. Finalmente, se encontró cierta evidencia que durante los períodos en los cuales existe la posibilidad de que ocurran estas intervenciones, las tasas de interés son ligeramente más elevadas que en los períodos en los que esta posibilidad no se presenta. Este resultado puede reflejar ciertas distorciones de caracter temporal que surgen en el mercado de dinero al realizarse las operaciones de esterilización.

The successful realization of the climate goals agreed upon in the European Union’s COP21 commitments makes a fundamental change of the European energy system necessary. In particular, for a reduction of greenhouse gas emissions over 80%, the use of renewable energies must be increased not only in the electricity sector but also across all energy sectors, such as heat and mobility. Furthermore, a progressive integration of renewable energies increases the risk of congestions in the transmission grid and makes network expansion necessary. An efficient planning for future energy systems must comprise the coupling of energy sectors as well as interdependencies of generation and transmission grid infrastructure. However, in traditional energy system planning, these aspects are considered as decoupled. Therefore, the project PlaMES develops an approach for integrated planning of multi-energy systems on a European scale. This paper aims at analyzing the model requirements and describing the modeling approach.

In a real Hilbert space H consider the following singularly perturbed Cauchy problem. We study the behavior of solutions uεδ to this problem in two different cases: ε → 0 and δ ≥ δ0 > 0; ε → 0 and δ → 0, relative to solution to the corresponding unperturbed problem. We obtain some a priori estimates of solutions to the perturbed problem, which are uniform with respect to parameters, and a relationship between solutions to both problems. We establish that the solution to the perturbed problem has a singular behavior, relative to the parameters, in the neighbourhood of t = 0.

This article considers the two-stage fixed-charge transportation problem which models an important transportation application in a supply chain, from manufacturers to customers through distribution centers. For solving this optimization problem we describe a hybrid algorithm that combines a steady-state genetic algorithm with a local search procedure. The computational results for an often used collection of benchmark instances show that our proposed hybrid method delivers results that are competitive to those of other state-of-the-art algorithms for solving the two-stage fixed-charge transportation problem.

In tropical countries, there is a need for air conditioning systems, especially for high-rise buildings to provide comfort for their residents. For this reason, it is necessary to plan an air conditioning system using a ceiling duct with a VRV / F (Variable Refrigerant Volume / FLOW) system setting so that the load and capacity are appropriate and more efficient. In calculating the cooling load, starting from the sensible load and the load, and calculating the size of the ducting. The research method used to plan an air conditioning system using a ceiling duct with VRV / F system settings is the observation method by taking the required data. Perform calculations and analysis with the data obtained. So that after planning the total load on the 5th floor = 270,752.79 Btu / hr (79.3498kW), the 6th floor = 280,568.37 Btu / hr (82,227 kW), and the 7th floor = 229,690.66 Btu / hr (67.3157kW). The size of the ducting supply used is: Height = 75mm-450mm, Width = 75mm - 450mm and the size of the ducting return used is Height = 75mm-450mm, Width = 75mm-450mm. From the planning results, it is determined that the air conditioning system uses a ceiling duct system with VRV / VRF system settings. The advantages are Easy Maintenance, high reliability, large capacity use, space-saving design, different indoor units in one system, and using R410 type refrigerant.
