Wireless Mesh Network (WMN) [1] deployment based on IEEE 802.11s [2] standard is a popular choice in setting up cost-efficient alternative to support broadband internet services to a larger population. They can provide network connectivity over large geography when compared to WLANs. WMN makes use of Distributed Coordination Function (DCF) Medium Access Control (MAC) protocol with Binary Exponential Backoff (BEB) algorithm to avoid collision due to simultaneous transmissions by more than one user at the same time. These collisions bring the network performance drastically down if not handled properly. Thus this work tries to evaluate the suitability of the better efficient CA algorithms (EIED, EILD, MILD, PB, CCW, EBO, HBA…) which can replace BEB to support higher throughput for IEEE 802.11s networks (WMNs). The NS-3 [3] simulation results indicate that Polynomial Backoff (PB) performs better than others against the BEB algorithm in about 52 % of network scenarios and it is suggested to operate with TWO radios enabled with all access points.

In the present paper, we investigated the problem of the propagation of blast waves governed by a nonhomogeneous quasilinear hyperbolic system of partial differential equations (PDEs), describing one-dimensional unsteady motion with generalized geometries in a real gas flow (van der Waals gas) in which the influence of the dust particles is significant. An efficient analytical approach has been used to the governing hyperbolic system with respect to the Rankine-Hugoniot (RH) conditions to obtain an exact solution in terms of flow parameters density, velocity and the pressure, which exhibits space-time dependence. Further, an analytical expression for the total energy influenced by real gas effects (consisting of non-ideal gas and small solid dust-laden particles) is derived. The results obtained significantly explore the effect of dust-laden particles on the propagation of blast waves in a van der Waals gas.

The Visual Secret Sharing is the technique in which secret information is hidden in the form image which then divided into shares and these shares are used to decrypt the secret information. The number of shares required is given by the creator of the secret. Minimum those many shares are needed in order to decrypt the secret. If a single share is missing then the secret cannot be decrypted. The Quick Response (QR) code gives quick access to the information contained in it. QR code is 2D representation of the barcode which has capability to store information and can be easily read by machine. Due to easy access to the information stored in it, it is necessary to use some encryption or other protection to the data. Proposed approach to visual secret sharing scheme divides a secret QR code into different shares. In addition, the secret message is recovered by using XOR operation of the shares. This can effortlessly be achieved with the use of smartphones or different QR scanning gadgets. Using optimal partitioning methods the decryption of the message is made difficult to the hackers giving additional security to the data. The message accuracy can be checked by comparing the original message with shared message using hashing techniques. Because the QR code are small in size and has high data storage capacity, it is also resistant to damage so that is information is not lost even if some portion of the QR code is damaged it is best image to be used in visual secret sharing. The proposed approach reduces the risk of data transmission attacks.

The purpose of this article is to localize underwater objects based on the noise reflection of the propeller rotation in cavitation mode. In the proposed method, the propeller noise, which plays the role of pings in active sonar, is modeled by the Wittekind method. As such, an echo is continuously received by a vertical and uniform linear hydrophone array due to reflection from the underwater targets. The challenges associated with the underwater channels are simulated by the ocean model in COMSOL. Specifically, to model the propagation of underwater acoustic in this channel, the Helmholtz equation is solved using COMSOL. Finally, localization is performed by comparing the Delay & Sum algorithm and the multiple signal classification (MUSIC) algorithm in MATLAB. According to the simulation results, the proposed method is able to detect the position of the target and the propeller approximately, although the multipath phenomenon causes adverse effects on the results. The narrowband MUSIC algorithm is used in the proposed method at the frequency of the strongest intensity.

Harmonious Wireless Networks: From the Perspective of Interference Management
Authors: Liu Wei
Published: March 2020

 In wireless networks, the
desired signal of a specific user is typically an undesired interfering signal
for untended receivers. However, from
the perspective of an entire wireless network, the coexistence of useful
signals and interfering signals is unavoidable and often is beneficial in
throughput terms. The useful signals and
interfering signals are complementary.
They are in juxtaposition to each other in the context of a single
communication link, while they are in symbiosis within the framework of the
networks, which can be described by Chinese traditional culture symbol of “Yin”
and “Yang”. A wireless network having optimal performance must be a harmonious
network, where the interfering and useful signals harmoniously coexist in an
optimal balance. Interference management
plays the critical role in arriving at this optimal balance.

Authors: Poejilestari Noening
Published: March 2020

The purpose of this study is to determine the morphological errors and syntactic errors made by students in writing recount text, frequency of errors, types of dominant errors and sources of errors. The research method used is qualitative research. The data from this study are 70 recount texts made by students of tenth grade in SMK Negeri 9 Kota Bekasi. The research found that there were still many mistakes made by the tenth grade students of SMKN 9 in Bekasi in writing English recount text. For morphological errors the researcher found that students made 56 errors which included single errors with the number of errors 4 (7.14%), plural form errors with number of errors 5 (8.93%), errors belonging to the number of errors 8 (14.29%), errors to infinitive with the number of errors 9 (16.07%) and the formation error in the past with the number of errors 30 (53.57%). While for syntactic errors, the researcher found that students made 113 errors which included omission errors with 47 errors (41.60%), addition errors with 24 errors (21.24%) and formation errors with 42 errors (37.16%). This shows that grammar is a weakness of students in writing essays, especially recount text. From the results of the study it was found that students experienced obstacles in writing caused by interlingual factors, intralingual factors and excessive generalization. Thus students' writing skills are still weak.

Hepatic involvement of infectious origin not related to hepatotropic virus
Authors: Gálvez Fernández RM , Rosales Zábal JM , García Gavilán MC
Published: March 2020

El hígado es un órgano implicado en múltiples funciones orgánicas. Debido a su localización anatómica y sobretodo a su anatomía vascular especial, con llegada a su parénquima de flujo venoso portal proveniente de intestino y bazo principalmente y de flujo arterial a través de la arteria hepática formando parte de la circulación sistémica, hace que el hígado esté especialmente expuesto a diferentes agentes patógenos, principalmente de origen viral, sin poder olvidar a las infecciones bacterianas, parasitarias y fúngicas. La importancia de este hecho hace que el gastroenterólogo cuando está evaluando a un paciente con hipertransaminasemia, además de descartar las principales causas de las misma, en función del contexto clínico y de los datos epidemiológicos, recuerde la necesidad de descartar causas infecciosas menos habituales que podría justificar una alteración del perfil hepático que en ocasiones puede representar cierta gravedad, sobretodo si no se diagnostica y se indica el correcto tratamiento específico que incluso, a veces, requiere de tratamientos invasivos o cirugía. Revisaremos las principales causas infecciosas que pueden producir daño hepático, sin considerar a los virus hepatotropos, es decir, los virus no hepatotropos, bacterias, parásitos y hongos.
Double pylorus: unusual endoscopic finding in peptic disease.
Authors: Díaz Alcázar MM , Ruiz Rodríguez AJ , Martín-Lagos Maldonado A
Published: March 2020

Hombre de 59 años que consulta por melenas y vómitos en posos de café. En tratamiento con heparina desde una semana antes. Se realiza endoscopia digestiva alta objetivando doble píloro y úlcera Forrest IIa de 2 cm en cara anterosuperior de bulbo.

El doble píloro o fístula gastroduodenal es un hallazgo endoscópico raro. Se debe a la formación de una fístula entre el estómago y el duodeno. Su incidencia es menor del 0.4%. Como en el caso presentado, habitualmente se forma en el lado de la curvatura menor. Puede ser congénito o adquirido. El doble píloro congénito es extremadamente raro. El doble píloro adquirido se relaciona con la enfermedad péptica gástrica. En la mayoría de los casos la fístula no cierra aunque cicatrice la úlcera.

Authors: Méndez Niño Yolman Manuel , Pereyra Mario
Published: March 2020

Esta investigación procuró determinar si existen efectos significativos del estilo educativo parental, según la percepción de los hijos, sobre el rendimiento académico y la religiosidad intrínseca en los estudiantes de una escuela preparatoria cristiana del noreste de México. Se utilizaron tres instrumentos: (a) la Escala de Estilos Parentales, compuesta por 41 ítems, (b) la concentración de calificaciones del sistema académico de nivel medio y (c) la Intrinsic Religious Motivation Scale (IRM), que consta de 10 ítems. La muestra contempló a 116 estudiantes de nivel medio. Se encontró que existen efectos significativos del estilo educativo parental, en sus dimensiones control conductual y control psicológico, sobre el rendimiento académico de los estudiantes. Existen efectos significativos del estilo educativo parental, en sus dimensiones control conductual y revelación, sobre la religiosidad intrínseca de los estudiantes. En general se concluyó que el estilo educativo parental, según la percepción de los hijos, produce efectos significativos sobre el rendimiento educativo y la religiosidad intrínseca del estudiante, aunque la relación, tanto en el caso del rendimiento académico como de la religiosidad intrínseca, no se da con todas las dimensiones del estilo educativo parental.

Esta investigación tuvo el propósito de conocer la validez de constructo y la confiabilidad del instrumento de imagen de instituciones educativas universitarias. Se eligió en forma no aleatoria una muestra de 314 estudiantes de bachillerato de Montemorelos, Nuevo León. Se utilizó un instrumento con 25 declaraciones para medir la imagen de la Universidad de Montemorelos (confiabilidad α = .956). Al realizar la validez de constructo se observó que las declaraciones se agruparon en cuatro dimensiones como se había propuesto inicialmente. A excepción de un ítem, todos los demás se agruparon en la dimensión propuesta. En la validación de constructo utilizando ecuaciones estructurales, la mayoría de los criterios seleccionados se cumplieron.

Published: March 2020

Existe la constante búsqueda para mejorar el aprovechamiento académico matemático en los alumnos de nivel secundario; por lo tanto, surge la necesidad de conocer si existe relación entre la capacidad de memoria de trabajo y la actitud hacia las matemáticas en los estudiantes. La investigación es cuantitativa, descriptiva, ex post facto y transversal. Participaron 137 estudiantes de una escuela secundaria de Veracruz, México. Se aplicaron cuatro instrumentos de medición (tres de memoria de trabajo y uno de actitud hacia las matemáticas), los cuales fueron validados en investigaciones previas. Para el análisis de los datos se aplicaron el coeficiente de correlación r de Pearson y el ANOVA de un factor. No se encontró una relación significativa entre la capacidad de memoria de trabajo y la actitud hacia las matemáticas en los estudiantes de secundaria, en general. Sin embargo, en el análisis por grados se encontró una relación significativa entre la capacidad de memoria de trabajo y la actitud hacia las matemáticas en los estudiantes del segundo grado. También se encontró que la actitud hacia las matemáticas varía en los diferentes grados del nivel secundario, observando que el primer grado obtiene mayor promedio que el segundo y el tercero.
