Published: April 2022

The subject of the article is the processes of synthesis of a mathematical model of control objects functioning in computer information-control systems of critical purpose for the needs of high-speed railway transport. The main emphasis is on modeling the movement of a passenger train in the high-speed system of Ukrzaliznytsia. The aim is to study the process of regulating the speed of railway vehicles under conditions of uncertainty in the primary information of microprocessor information-control systems of railway transport. Tasks: determination of the criterion of the safety of railway vehicle auto control; obtain a mathematical model of train movement under conditions of uncertainty; check the adequacy of the model. The method used is the mathematical apparatus of discrete models. The following results have been obtained. The mathematical model of train movement developed in this work includes not only information on train position, reference point, direction, and speed of the vehicle but also a variable control indicator to reflect the process of railway traffic adequately. The study shows that, based on the synthesized model, it is possible to use the so-called fuzzy distance between adjacent trains. This approach improves the accuracy of determining the critical distance between trains, the time required to eliminate the risk of collision, the start time of braking, and braking time considering the angle of inclination of the track, as well as the distance of the braking distance. The necessity to determine the control indicator, its value for many points of time, while there is a reduction in speed for the safe movement of trains. Based on the proposed mathematical model, a computer simulation of the process was performed to determine the required time reserve for the train driver to respond to changes in the speed of the previous train, as well as speed ranges that require immediate emergency action. Conclusions. The scientific novelty of the obtained results is the development of a mathematical model of the behavior of mobile units in computer systems for critical use for the needs of railway transport in the presence of failures in the primary information from sensors that record motion parameters. The behavior of the control system at different values of train speed and changes in the value of the interval of the accompanying journey is studied. The theory of traction calculations in computer control systems for mobile units has been further developed. The obtained scientific results will be used in the development of an application program for many critical computer systems for railway.

Authors: Kurennov Sergiy , Barakhov Kostiantyn , Taranenko Igor , Stepanenko Volodymyr
Published: April 2022

A genetic algorithm for solving the problem of optimal beam material distribution along length at a given restriction on maximum sagging value is suggested. A review of literature sources is conducted and it was shown that existing solutions cover partial cases only in which the position of the point with maximum sagging was defined previously. In the paper presented I-section beam with constant proportions is considered, i.e., beam width, caps, and web thickness are proportional to beam height in the current cross-section. A statically determined beam is being considered. The load applied to a beam can be arbitrary, including cases of non-symmetrical loads and differently oriented ones. The position of point(s) at which beam sagging is maximum are unknown at the beginning of optimization and are found in the process solution. The problem is solved in the linear definition. Beam mass was assumed to be an optimization criterion. The method of finite differences is used for beam sagging finding, i.e., for the solution of the differential equation of the bending beam with a variable cross-section. Discretization allows transforming the problem of design into the problem of beam height determination at a system of reference points. At this stage, found values of beam height must satisfy restrictions on reference point displacements. The suggested technique allows controlling beam displacement quite flexibly because restrictions on point displacement are considered separately and do not depend on each other. The suggested objective function is the linear superposition of beam mass and the possible penalty in case of beam maximum sagging over exceeding predefined values. The application of a genetic algorithm allows getting sets of beam thicknesses those, which guaranty reaching the minimum of the objective function. The model problem is solved. It is shown that the suggested algorithm allows effectively solves problems of optimal design of beams with restrictions on the maximum sagging value. The suggested approach can be developed for strength restrictions, statically undetermined structures, etc.

Published: April 2022

The dielectric material used as a substrate and the shapes of the patches play an important role in the performance of bandwidth, return loss, and gain of the microstrip patch antenna. This paper presents the relative study of different shapes of microstrip Patch antenna for different dielectric materials. The main application of these antennas is for satellite communication in Ku-Band. The height of the substrate plays an essential role in the enhancement of bandwidth and it is chosen 1.012mm and three substrate materials (RT Duroid (5880), Teflon, and FR4) with different dielectric constants were chosen for the performance comparison. Aperture coupling, which is again one of the promising techniques for bandwidth enhancement, is used as a feeding technique for the designs. Coupling must be taken care of while using aperture coupling, which is done by precisely optimizing the feed line dimensions, feed position, slot dimensions, and patch dimensions. The antenna performance is studied by varying the parameters like patch, feed line, and slot dimensions, the size of the substrate, and the feed line position concerning the slot. Optimization is also performed for the position of the ground layer within the substrate material and the ground plane in the middle position of the substrate is chosen for the final designs. Return loss and impedance matching were analyzed for all designs. The rectangular and circular patches are used for a comparative study, which is conducted from 12GHz to 14GHz out of which the circular patch is found to give better performance. The analysis is carried out for RT Duroid (5880) material and the bandwidth obtained in both cases is almost 3GHz. Similarly, the analysis is carried out for different dielectric materials over the frequencies of 12GHz to 14GHz in which RT Duroid and Teflon give better performance in terms of return loss and FR4 gives better performance in terms of miniaturization. The analysis is carried out for rectangular patches and the bandwidth obtained for FR4 is 1GHz whereas, for RT Duroid (5880) and Teflon, it comes out to be 3GHz. The results are depicted in various tabular and graphical formats. This study is conducted using an HFSS, an electromagnetic solver.
Adaptive identification under the maximum correntropy criterion with variable center
Authors: Rudenko Oleg , Bezsonov Oleksandr
Published: April 2022

The problem of identifying the parameters of a linear object in the presence of non-Gaussian noise is considered. The identification algorithm is a gradient procedure for maximizing the functional, which is a correntropy. This functionality allows you to get estimates that have robust properties. In contrast to the commonly used Gaussian kernels, the centers of which are at zero and effective for distributions with zero mean, the paper considers a modification of the criterion suitable for distributions with nonzero mean. The modification is to use correntropy with a variable center The use of Gaussian kernels with a variable center will allow us to estimate unknown parameters under Gaussian and non-Gaussian noises with zero and non-zero mean distributions and provide an opportunity to develop new technologies for data analysis and processing. It is important to develop a robust identification algorithm based on correntropy with variable center. Their properties in the identification of stationary and non-stationary objects are the subject of research. The goal is to develop a robust identification algorithm that maximizes the criterion of correntropy with a variable center using center configuration procedures and kernel width and to study its convergence in stationary and non-stationary cases under non-Gaussian noise. Expressions for steady-state value of the estimation error are obtained, which depend on the type of noise distribution and the degree of non-stationarity of the estimated parameters The following tasks are solved: to investigate the convergence of the algorithm and determine the conditions for the stability of the established identification process. Methods of estimation theory (identification) and probability theory are used. The following results were obtained: 1) the developed algorithm provides robust estimates in the presence of noises having a distribution with zero and non-zero mean; 2) its convergence was studied in stationary and non-stationary cases under conditions of Gaussian and non-Gaussian noise; 3) simulation of the algorithm was carried out. 1) the developed algorithm consists in the development of a robust identification algorithm that maximizes the criterion of correntropy with a variable center; 2) its convergence in stationary and non-stationary cases in the conditions of Gaussian and non-Gaussian noises is investigated; 3) simulation of the algorithm is performed. Conclusions: The results of the current study will improve existing data processing technologies based on robust estimates and accelerate the development of new computing programs in real time.

The “Reading the Mind in the Eyes test” (RMET), also known as “The Eyes test”, is one of the most widely used tests to study Theory of Mind (ToM) and has been translated to several languages around the world. The aim of this study was to present an online version of the RMET designed for a Mexican population (Barrera-Valdivia et al., 2019) and to explore sex and age-related effects on the performance of the test. 1489 adults (1054 female, 71%) age 18 to 87 (M=30, SD=15) participated in the study. Participants were instructed to choose the word that best described what the person in each picture was feeling among four options. Stimuli consisted of full color images of 45 people’s eyes who expressed a variety of mental states. Results showed that 30 stimuli met the selection criteria: ≥50% selected on target and ≤25% on any of the foils. Average accuracy in response was 76% (SD= 11%) with observable differences by sex and age. Response accuracy allowed to classify stimuli into three difficulty levels (easy, intermediate, and difficult). Results showed that the online version of the RMET is an adequate assessment tool for ToM research in Mexican population as well as other Latin Americans communities that share cultural features.
Transformación de la memoria: consolidación, reconsolidación y error de predicción
Authors: Zárate Rochín Alba Marcela , López-Riquelme Germán Octavio
Published: April 2022

El proceso de consolidación de la memoria fue tomado de la psicología para ser estudiado en el campo neurobiológico con la finalidad de dar cuenta de cómo se conserva la información en el cerebro a largo plazo. En principio, este programa de investigación se basó en la idea de que una vez adquirida una memoria, en condiciones normales, se vuelve estable y persistente. Sin embargo, una gran diversidad de estudios ha demostrado que una memoria, a pesar de su temporalidad, sigue siendo sensible a la interferencia. Más aún, la evidencia sugiere que la experiencia en curso reactiva y actualiza a la memoria. Por ello, se propuso un proceso de reconsolidación que parece depender del grado en que la información actual se desvía de lo que predice la memoria reactivada. En ese sentido, en esta revisión, se analizan los enfoques tradicionales sobre la consolidación y reconsolidación de la memoria y se ofrecen algunas ideas más recientes sobre la naturaleza de la transformación de la memoria con base en el procesamiento del error de predicción, en distintos niveles de análisis.

Published: April 2022

Los videojuegos de estrategia en tiempo real (VJ-ETR) requieren que los jugadores planeen estrategias reclutando capacidades cognitivas como atención, habilidades motoras, habilidades visuoespaciales y memoria de trabajo (MT). Ya que jugar VJ-ETR depende del mantenimiento de metas principales y submetas activas, así como de la revisión dinámica de esas metas conforme la situación lo requiere, el objetivo de este trabajo fue estudiar si jugadores expertos de VJ-ETR (JExp-ETR) tienen una mayor capacidad de MT que no-jugadores (No-ETR). Para ello, comparamos el desempeño entre JExp-ETR y No-ETR en MT y velocidad de procesamiento (VP) empleando el Wechsler Adult Intelligence Scale (WAIS-IV) y la tarea n-back. Los resultados muestran que los JExp-ETR tienen un mayor índice de MT y una mejor precisión en el n-back que los No-ETR, principalmente en el 3-back, pero no encontramos diferencias en VP. Además, también encontramos que los JExp-ETR que juegan más horas a la semana tienen un mayor índice de MT que los JExp-ETR que juegan menos horas. Los resultados son discutidos en el marco de la capacidad de la MT, la importancia de los VJ-ETR y sus efectos en la cognición.
Cognición social: del antropocentrismo a la cognición social comparada
Authors: López-Riquelme Germán Octavio , Gómez-Gómez Yvette Magaly , Solís-Chagoyán Héctor
Published: April 2022

A pesar de ser una visión dominante, el programa antropocéntrico presenta errores en la manera en la que entiende la evolución de la cognición social, ya que su sistema de comparación tiene como base el ser humano. El programa ecológico, por otra parte, señala este error y propone que la base de la comparación debe ser ecológico-adaptativa, es decir, que la sofisticación de la cognición social, y por consecuencia del grado de complejidad social de las especies, surge de demandas ambientales que promueven la cooperación entre individuos y no de su cercanía filogenética con el humano. En el presente trabajo, realizamos una crítica de la perspectiva antropocéntrica dominante de la investigación en cognición social; asimismo, proponemos que este campo debe ampliarse y partir de la perspectiva ecológica del estudio del comportamiento y la cognición mostrando el vacío teórico y sintético que nos urge a realizar una síntesis de la cognición social comparada.
Salvia divinorum: un estudio fenomenológico y cognitivo de la experiencia en usuarios de Latinoamérica y España.
Authors: Nava-Gómez Laura , González-González Juan Carlos
Published: April 2022

La planta Salvia divinorum (Ska pastora, Hierba María, María Pastora), es una planta endémica mexicana de la familia de las mentas, con larga historia de uso tradicional entre nativos de la Sierra de Oaxaca, en México. Se emplea en prácticas religiosas, curativas y adivinatorias, y es uno de los componentes principales de ceremonias de sanación física y espiritual, siendo beneficiosa tanto para tratar afecciones gastrointestinales como para tratar el alcoholismo, entre otras. En ambientes urbanos industrializados de Latinoamérica y España, su uso recreativo se ha extendido y sus efectos subjetivos están todavía poco documentados en la literatura científica con validez ecológica, lo que limita el conocimiento sobre sus efectos en ambientes poco controlados. Comprender el uso no-tradicional contemporáneo es deseable (y quizás necesario) para evitar los consumos problemáticos y explorar potenciales usos benéficos —ya sean terapéuticos, clínicos o cognitivos— sobre todo de cara a la inminente legalización de las sustancias psicodélicas en muchos países del mundo. Este estudio se enfoca principalmente en el aspecto subjetivo de la experiencia con Salvia divinorum y en su interpretación post-facto, analizando la percepción y otros procesos cognitivos y emocionales propios de la experiencia en usuarios contemporáneos. Se concluye que un uso planificado de la Salvia divinorum podría tener efectos positivos en términos terapéuticos y como potenciador cognitivo. Sin embargo, es necesario profundizar la investigación e incluir métodos cuantitativos de las ciencias cognitivas para integrar un conocimiento sólido de su psicofarmacología y neurofenomenología.

In this study, the synthesis was carried out with various sintering time, 6 hours, 8 hours and 10 hours. The raw materials used in this study are manganese dioxide (“MnO2”), iron (III) oxide (“Fe2O3”), lithium fluoride (“LiF”) and phosphoric acid (“H3PO4”) as the solvents. The synthesis was carried out at a calcination temperature of 720°C for 8 hours. The first mashed use a milling process for about 180 minutes, and placed into the oven, then mashed using a mortar. Then the Mn0.5Fe0.5PO4 sample was added with LiF, mixed with the milling process, placed into a drying oven and was varied with the sintering time of 6 hours for the first sample, 8 hours for the second sample and 10 hours for the third sample. As to produce LiMn0.5Fe0.5PO4F material, followed by carbon coating, namely tapioca and sugar (8%:4%). All three samples were calcined at a temperature of 720°C for 4 hours. The results of XRD analysis showed that the three samples did not experience a phase of change, however only shows a few differences in intensity. The results of FESEM analysis show that grain growth occurs vertically and horizontally due to the presence of the Mn and Fe, and with an exact enough amount of tapioca function as a carbon source to coat the active material, it help to creates pores in the powder so that the presence of these pores could provide an intercalation pathway for the lithium ions. At the end the results of the EIS analysis showed that the highest conductivity value of this study was 0.62 x 10-5 S/cm.

Published: April 2022

The Holy Quran is a miraculous and irresistible book and it is a solid word with a strong and solid structure in which the literary industry can be understood with full clarity. One of the most important aspects of the expressive miracle of the Qur'an is the accuracy in using the words and secrets hidden in the reason for choosing each of its letters and words. Accordingly, the Holy Qur'an is free from all defects and shortcomings, such as: "ugly and mediocre obscenity", which in rhetoric is referred to as "condemned obscenity". However, in some Qur'anic verses and phrases, we see the useless repetition of the contents of the previous contents and what is apparently reprehensible, the main purpose of this study is to examine the dimensions and aspects of this group of Qur'anic verses in clear It is an expression and explanation that has been quoted from the great commentators. In this research, an attempt has been made to explain the semantic position of this group of non-verbal repetitions according to their theories and views (commentators). The reader should note that the spiritual repetition that has occurred in some verses includes rhetorical benefits such as emphasis, reproduction, and exaggeration, which are considered as literary arrays and give beauty and glory to speech.
Role of Instructor Qualifications, Assessment and Pedagogical Practices in EFL Students’ Grammar and Writing Proficiency
Authors: Al-Jarf Reima
Published: April 2022

Three groups of EFL freshman students were concurrently enrolled in a grammar and a writing course. One group was taught the grammar and writing courses by the same instructor; the other two groups were taught grammar and writing by two different instructors using the same textbook but different instructional and assessment techniques. The study aims to find out which group made higher gains in grammatical knowledge and writing skill development. It also aimed to find out the effects of instructor qualifications, assessment, and pedagogical variables on students’ grammatical competence and writing skill development. Comparisons of the grammar and writing post-tests showed significant differences between the three groups in the writing and grammar post-test mean scores. There were strong correlations between the grammar and writing post-test scores. Performance of the Group that received a combination of writing and grammar instruction by the same instructor (Instructor A) was the highest. The relationship between grammar and writing instruction seems to be reciprocal: writing instruction affects grammatical competence and grammatical knowledge affects writing skill development. Better achievements were made when both courses were taught by the same instructor as she can make the right connections between what is taught in both courses, which specific structures and skills should be emphasized.  The instructors’ qualifications, pedagogical system, educational and professional experience, the integration of online instruction, the type of error correction and instant feedback given to the students and the formative assessment technique used were significantly more effective than writing/grammar instruction that depended on the textbook alone. These variables proved to be important for enhancing the grammatical knowledge and writing quality of unskilled, low ability EFL students and resulted in a significant improvement in their grammar and writing post-test scores.
Religion, Culture, and Education in Development, Reading Soedjatmoko's Perspective: A Preliminary Note
Authors: Ayu Ambarwati
Published: April 2022

This article explains Soedjatmoko's view on the role of religion, culture and education in human development in Indonesia. The role of religion and culture and education in various changes and challenges of the times can be read from the perspective of individual personal interests and the interests of society. The problem is, in its purpose and method, the two functions are not always compatible and even contradictory. For in achieving personal perfection a religious person can focus his life and practice on a personal and direct relationship with God, and become indifferent to his society. That is why, Soedjatmoko also emphasized the importance of the social function of religion and culture to strengthen belief in relation to the development of education towards the future. In this case, religion, culture and education can mutually enrich the civilization of the Indonesian people as long as the constructive and positive values in them can be utilized for humanity, civility and mutual progress.
Ethical (Dis) Comfort in John Maxwell Coetzee’s Age of Iron (1990)
Authors: Saliou Dione
Published: April 2022

This article is concerned with making visible ethical (dis)comfort in John Maxwell Coetzee’s Age of Iron (1990) as it unearths how feelings of comfort and/or discomfort shape the individual when associated with ethics across boundaries of inequality, racism, violence, poverty, injustice rather than with the development trust in government and public institution. The inference here is that one of or the two feelings are necessary found in the individual experiencing directly or indirectly the Apartheid system. Therefore, faced with the humanitarianism system, the ontological assumption that underpins the argument, named the characters involved in the situation of ethical (dis)comfort, rests on the embodied, situated, affective, and creative dimensions of their expressions. Leaning on Aristotle’s rhetorical strategies of ethos, logos and pathos, normative ethical theory, axiology, and onomastics, the article analyzes the shift from moral dis-ease to normative ethics by uncovering the socio-psychological development processes and the creation of a space of consciousness and imagination through the author’s (re)conciliation paradigm and multi-racial nation ideal.

Published: April 2022

Introduction: Coronary angiography is traditionally performed through transfemoral access. Transradial access is increasingly being used for this purpose for its various advantages. However, its use in Bangladesh is less well studied. The aim of this study was to find out the safety and efficacy of transradial access as compared to transfemoral access.
Methods: This was a single-center, cross-sectional study. 100 randomly selected elective coronary angiography from August 2017 to September 2018 by the same operator using either transradial access or transfemoral access were analyzed.
Results: Among 100 coronary angiography, transradial access were 50 and transfemoral access were 50. Fluoroscopy time was 3.08[1-9] vs 1.47 [1-17] minutes (p=.014), dose area product was 4807 [1947-11489] vs 3202 [1130-12826] ìGy.m2 (P<0.001), total dose was 788 [276-2055] vs 520 [158-2424] mGy (p<0.001). Transradial failure occurred in 4 (8%) cases. Transfemoral failure occurred in 1 (2%) case. There was no significant difference in failure rate between the groups (p= 0.169). Ecchymosis was the commonest (10% in transradial access vs 22% in transfemoral access, p= 0.102) among post procedure complications. Other complications like thrombophlebitis (6% vs 18%, p=0.004); hematoma (0% vs 12%, p= 0.005); puncture site bleed (2% vs 4%, p= 0. 039) were seen in TRA and transfemoral access, respectively.
Conclusion: Access site complications are more in transfemoral access. Transradial access is an effective alternative to transfemoral access, and it can be performed safely by experienced operators.
