Published: April 2021

A novel and compact antenna element is analyzed and designed to achieve an efficient 4x4 MIMO antenna for a mobile phone at 3.5 GHz band for 5G communication. FTDT and FEM techniques are used to analyze and compare modeling accuracy of the proposed
MIMO antenna. It has achieved a minimum isolation of 19.7dB between two antennas with radiation efficiency of 86%. The improved isolation and efficiency for the proposed MIMO antenna has been achieved without any decoupling structure between antennas, instead larger separation between elements due to compact size of the proposed element facilitated to achieve good performance. Pattern diversity is also achieved by arranging adjacent asymmetric antennas in reverse direction with each other. The envelope correlation coefficient (ECC) is less than 0.002 and Channel Capacity loss (CCL) is also less than 0.4 bps/Hz in the whole frequency band (3.36-3.66 GHz), which is suitable for 5G MIMO systems.

Published: April 2021

This work presents a comprehensive detailed comparative study of the three ultra-wideband and high directive antennas for the THz imaging, spectroscopy, and communication applications. Three different types of photoconductive antennas (log-spiral, Vivaldi, and bowtie antennas) are designed and simulated in the frequency range of 1 to 6 THz in the CST microwave studio (MWS). The enhanced directivity of the designed PCAs is achieved with the integration of the hemispherical silicon-based lens with the PCA gold electrode and quartz substrate of the proposed antennas. The performance of the designed PCAs is compared in terms of impedance and axial ratio bandwidths, directivity, and radiation efficiency of the proposed antennas. The reported log spiral, Vivaldi PCAs with added silicon lens exhibit the -10 dB impedance bandwidth of 6 THz, 3dB AR bandwidth of 5 THz, 6 THz, and 6 THz and peak total radiation efficiencies of 45%, 65%, and 95% respectively.

Published: April 2021

Education services are meant for developing the cognitive capacities of all individuals, though this may vary with individuals given their variable genetic make-up. Early childhood education is one way in which children are developed for the future. This study sought to establish how early childhood education services were valued, made available and accessible to children in a developing country. Open-ended interviews and observations were the instruments used for data collection. Thematic analysis was the data analysis method used in this study. The findings of the study revealed that there were benefits in preschool education and that those learners who missed early childhood education were slow and took long to grasp concepts. The study also found that in the Kingdom of Eswatini not all children of early childhood going age go to school due to limited finances, poverty and sicknesses. The study concluded that privately-owned early childhood development centres are expensive and most parents could not afford the fees. The study recommended that the ministry should consider ECE and start funding preschool education and also provide a documented curriculum to ensure that children who attended preschool get the required skill as expected. The Ministry of Education needs to provide for ECE if they have to achieve their goal of providing equal and quality education to all Eswatini children. The ministry should be prepared to build more preschools, to at least see each primary school having a preschool owned by the government linked to it

Методология археологических исследований могильников в Польше
Authors: Przysiężna-Pizarska Magdalena
Published: April 2021

Археология, как наука, имеет собственную проблематику проведения исследований, относительно которой разрабатывается подходящая методология исследований. Данная наука занимается открытиями в сфере прошлого человека, среды, в которой он работает, живет и умирает. Археология не занимается только лишь обнаружением предметов, которыми человек пользовался; она обнаруживает также археологический контекст, т.е. открывает места, где данные предметы были захоронены. На каждом археологическом объекте исследователь рассматривает исследуемую территорию с точки зрения трех ландшафтов. Первый ландшафт – природный, второй – поселенческий, и третий – ритуальный. Последний из трех ландшафтов связан с наименее изученной сферой – сферой обрядов и ритуалов. Область исследования ритуалов труднее всего интерпретировать, хотя она и кажется наиболее привлекательной среди исследователей. Соответственно, крайне важной является необходимость проведения полевых исследований вдумчиво и правильно. Многолетний опыт проведения полевых исследований позволил выстроить процессы таким образом, дабы облегчить исследование.

This study explores how newly arrived young students created meaning, communicated, and expressed themselves using digital technology in the subject of Swedish as a second language (SSL).  The qualitative case study presented in this article focuses on how the orchestration of teaching contributed to opportunities for digital meaning-making in the SSL subject in four classrooms at three schools in a city in Sweden. The notion of language as being fluid, which involves a critical approach to languages as separable entities, considers linguistic and embodied meaning-making, including digital technology, in social processes. This approach recognizes the roles of technology and digital meaning-making in young students’ second language acquisition. Moreover, technological innovations facilitate immediate and accessible communication.  In today’s language studies, ethnicity only is not considered an adequate focus of analysis. Furthermore, the meaning-making practices of newly arrived primary school-aged students remain under-investigated. In the present study, data collected in classroom observations and teacher interviews revealed three themes regarding the students’ utilization of digital technology to develop their multilingual skills. One insight was that the newly arrived students used digital technology strategically when they engaged in meaning-making activities with peers and teachers. When the students took the initiative in computer-assisted language learning, they displayed agency in meaning-making by being their own architects. The findings of this research provided insights into how the orchestration of teaching in Swedish as a second language to newly arrived students affects their opportunities to use multilingualism in meaning-making while employing digital technology.

Teaching English to Speakers of Other Languages (TESOL) teacher candidates must have a working knowledge of English linguistics in order to support their students’ language development. This article reports on TESOL teacher candidates’ reflective practice to highlight how interaction with non-native speakers can develop awareness of linguistic features of the English language through virtual exchange. Sixteen teacher candidates from a university in the United States were paired with 22 undergraduate English as a Foreign Language (EFL) learners from a university in Mexico. The teacher candidates completed journal entries in which they analyzed authentic language produced by their EFL partners during their virtual meetings. Teacher candidates were taking a course that covered topics related to pragmatics, semantics, morphology, phonology and syntax. Each teacher candidate submitted a final error analysis of recorded conversations to determine how many linguistic errors were made by their partners. This study describes the errors the teacher candidates were able to identify in order to explore the benefits of this reflective activity on their understanding of linguistics. This study confirms the need to utilize virtual exchange in teacher preparation programs and subsequent self-reflection in order to give teacher candidates a way to put linguistic content area into practice.
Review of "Disruptive Technologies and the Language Classroom: a complex systems theory approach"
Authors: Cengiz Behice Ceyda
Published: April 2021

Which dynamics of language learning and teaching change when traditional face-to-face language classrooms are moved to the online medium? And more importantly, does the advent of online technologies change the ways language teachers teach and language learners learn? In “Disruptive Technologies and the Language Classroom”, Hampel (2019) provides new insights into these important questions. She points out that online language learning and teaching destabilizes the language classroom by affecting its overall dynamics and by opening up new venues for language learning and teaching. By referring to her years-long experience in online language teaching and research, she argues that understanding the effects of these online technologies will better help language learners to communicate successfully in the second language (L2). Viewing communication as an aim and instrument in language learning, she focuses on the idiosyncrasies of computer-mediated communication and presents a theoretical discussion of computer-mediated communication’s unique features and affordances in reference to related literature.

Objetivo: Verificar se e quais padrões alimentares podem estar associados ao apetite emocional em mulheres acompanhadas pelo Sistema Único de Saúde (SUS). Métodos: Estudo quantitativo, transversal e analítico realizado em 20 Centros de Saúde da Família do SUS, entre 2016 e 2017, com mulheres de 19 a 59 anos, em idade reprodutiva e alfabetizadas. Coletaram-se dados de peso, altura e circunferência da cintura, e aplicou-se o Questionário de Apetite Emocional (QUEAPEM), para avaliar o apetite emocional, e o Questionário de Frequência Alimentar, para avaliar o consumo alimentar, analisado na forma de padrões alimentares derivados por análise fatorial por meio de testes de esfericidade de Barllet e Kayse-Meyer-Olkin. Verificou-se relação entre os padrões alimentares e a dimensão do apetite emocional pelo teste de Spearman, considerando significativos os valores de p<0,05. Resultados: Ao total, 149 mulheres participaram do estudo, com idade média de 34,3 ± 8,6 anos. A maioria das mulheres (n= 88; 59%) encontra-se com excesso de peso, sendo 25,5% (n=38) com obesidade. Identificaram-se três padrões alimentares que juntos explicaram 16,8% da variabilidade da dieta, denominados de “denso em energia”, “saudável” e “tradicional”. Houve correlação entre o padrão alimentar “tradicional” e a presença de apetite emocional em situações negativas (p<0,05), não havendo correlação com os demais padrões. Conclusão: A identificação de três padrões alimentares permitiu um melhor entendimento da alimentação das mulheres estudadas, além de detectar uma associação inversa, embora fraca, entre o padrão alimentar “tradicional” e o apetite emocional em situações negativas.

The occurrence of tremendous developments in the field of data has led to the formation of huge volumes of data, and it is normal that this leads to the presence of outliers in this data for many reasons, which may have small or large values ​​compared to the rest of the normal data, and the presence of outliers in the data affects the statistical analysis of this data, so we must try to reduce its impact in various ways. On the other hand, the presence of outliers ​​may be of great benefit, for example knowledge of geological activities that precede natural disasters such as (earthquakes, forest fires, floods ... etc.). Therefore, detection of outliers is of great importance in various fields. In this research, we aim to develop easy methods for detecting outliers in big data, as the problem that this research addresses is that many of the newly developed methods for detecting outliers suffer from computational complexity or are efficient when the sample size is small. An experimental approach was used in this research by suggesting three methods for detecting outliers, the first method is based on standard deviation and was tested and compared with the normal distribution method and the z-score method. The second method depends on the maximum and minimum value of the data, and the third method depends on the range between successive data points. The results of second and third methods are compared with Hample's Test method result. The accuracy of the results is measured based on the confusion matrix. The results of the proposed methods test showed the conformity of the first method with the results of the normal distribution method and the Z-Score method, as well as the superiority of the third method over the Hample's test method. In this paper, it was concluded that the Hample's test method suffers from a serious weakness when the zero values in the data constitute more than 50% of the number of elements.
An Efficient Grid-tied Flyback Micro-inverter with DCM Control Strategy
Authors: Yaqoob Salam Jabr , Obed Adel A.
Published: April 2021

In two-stage micro-inverter photovoltaic (PV) applications, DC/DC converter is used to obtain the highest DC power from the PV module. In this type of inverter, the rising of voltage from the PV module to a grid voltage level is limited to a certain value. Moreover, the absence of the isolation between the input and output makes it is less efficient. For these reasons, an efficient single-stage grid-tied flyback PV micro-inverter with discontinuous conduction mode (DCM) control strategy is proposed to feed an alternating current (AC) to the main grid with a lower value of the total harmonic distortion (THD). The control strategy is based on a sine sinusoidal pulse width modulation (SPWM) technique to control the main switch of flyback inverter. Also, a simple perturb and observe (P&O) maximum power point tracking (MPPT) technique has been presented to obtain the MPP point from the PV module for any environmental conditions. The proposed control was verified using PSIM software and simulation results is obtained. The proposed control is tested under different weather conditions for solar irradiance and temperature, as a result, a pure sin wave current has been injected into the grid with a lower harmonics value. Finally, the small size, low cost and high reliability of single stage flyback micro-inverter is presented without the need for DC/DC converter.
