Texte, contexte et documents numériques
Authors: Caro Stéphane
Published: October 2020

Le contexte est un élément déterminant pour la bonne compréhension d’un texte. Ce processus nécessite chez le lecteur la construction d’une représentation mentale du contenu depuis le texte. La lecture de texte sur écran rend particulièrement critique l’appréhension du contexte. En effet, la navigation hypertextuelle permet à l’utilisateur, par l’intermédiaire des liens, d’accoster sur un texte qui peut être une sous partie d’un ensemble appartenant lui même à un document ou un ensemble de documents. L’abstraction accrue des document numériques et en particulier la perte de tactilité avec le document fait disparaître des facilités cognitives habituelles disponibles sur support papier : indication du volume du document, de la position courante du lecteur, d’une partie du contexte. Les concepteurs de documents numériques doivent donc créer à nouveau et artificiellement ces facilités avec des organisateurs spécifiques. Par ailleurs, des systèmes de navigation « focus + contexte » vont permettre de situer le texte et le document dans des ensembles plus vastes et ainsi donner au lecteur de mieux appréhender le contexte lié à sa position courante. Nous présenterons un exemple de système de navigation de ce type et une expérience de validation auprès d’utilisateurs dans le cadre d’une tâche de recherche d’informations dans une base de textes descriptifs de logements. Le système présenté s’inspire des principes des théâtres de mémoire de l’antiquité qui permettaient de mémoriser des informations depuis un espace géographique.
La publication multisite : un objet linguistique qui interroge les notions de texte et de contexte dans les environnements numériques
Authors: Émérit Laetitia
Published: October 2020

La publication numérique est une forme techno - langagière (Paveau 2013) qui demande de repenser les notions de texte et de contexte tels qu’ils apparaissent dans les environnements numériques. La publication multisite est une forme récente et complexe de publication numérique qu’il est impossible de décrire sans proposer un cadre théorique et un métadiscours adaptés. Cet article, en proposant une définition de la publication multisite et une typologie des contextes de publication, amorcera une discussion sur ces notions. L’observation empirique, à partir de données collectées sur les réseaux sociaux numériques Facebook® et Twitter®, permettra d’analyser la relation texte/contexte dans le discours numérique natif.
Confiance en soi et métamorphose éducative
Authors: Moreau Didier
Published: October 2020

Cet article recherche comment, en éducation, la confiance en soi s’est trouvée étayée par la confiance dans l’éducateur. En distinguant confiance et séduction, on restitue à l’éducation son projet originel de conduire les sujets vers l’émancipation. Dans un premier temps, ce projet est examiné à travers la théorie de l’amitié chez Sénèque. Mais il faut comprendre l’aporie de la modernité qui construit la confiance en soi sur la défiance vis-à-vis de l’autorité. La solution qu’apporte l’herméneutique de Gadamer est questionnée dans la relation éducative. Le troisième problème abordé est celui de la destruction de la confiance en soi opérée par les institutions éducatives. Les essais d’Emerson sont un guide pour saisir ce processus et les remèdes qu’il préconise pour reconstruire la confiance en soi C’est enfin dans l’œuvre de Proust, considérée comme roman de formation, qu’on peut en lire la mise en pratique la plus achevée.
La salle de classe et le discours de l'enseignant
Authors: Oliveira Wanderley C.
Published: October 2020

Avec Hannah Arendt, nous avons identifié la rhétorique comme la forme spécifique du discours politique ; alors que la dialectique apparaît comme appropriée au discours philosophique. La rhétorique est destinée à la persuasion. Avec elle, le but est d'imposer le point de vue de l'un sur celui des autres. Avec la dialectique, ce qui est recherché, c´est parler de quelque chose avec quelqu'un. Ainsi, alors que la rhétorique produit le pouvoir de l'un sur l'autre, la dialectique favorise l'amitié avec l'autre. Entre ces deux façons de parler, où situer le discours de l'enseignant dans la salle de classe ? Pour tenir compte de cette question, nous avons d’abord caractérisé la rhétorique et la dialectique. Ensuite, nous avons préparé un tableau en les comparant. Enfin, nous essayons de voir ce qu’il peut arriver lorsque nous les relions au discours de l'enseignant dans la classe. Le discours de l'enseignement lié à la rhétorique, même s´il favorise la connaissance, vise, en dernier lieu, le pouvoir. D'où l'importance du passage par l'ironie comme recours en faveur de la dialectique, qui, au lieu du pouvoir de l'un sur l'autre, crée l'amitié fondée sur le respect et la confiance de l´un avec l'autre.
Confier et dire la vérité : pour réussir une communauté politique de production du lien éthique dans la relation pédagogique
Authors: Gallo Sílvio , Filordi de Carvalho Alexandre
Published: October 2020

Cet article vise à discuter la question de la confiance dans les relations pédagogiques établies dans les écoles et prend comme point central la notion de parrêsia proposée par Michel Foucault lors de l'étude des anciens textes grecs. Ce concept est présenté et commenté au long des derniers cours de Foucault, mais on utilise également la lecture contemporaine proposée par Maurizio Lazzarato dans ses récents ouvrages, qui problématisent principalement les aspects éthiques et politiques de la parrêsia. Dans le domaine des relations pédagogiques, on problématise les effets de « dire la vérité » et comment de nouveaux liens éthiques et de nouvelles relations de confiance (en soi-même et aux autres) sont produits à partir de tels actes parrésiastiques. Si Foucault en pensant la parrêsia a parfois pensé à la figure de l'enseignant, dans cet article le « dire la vérité » est considéré du point de vue des étudiants afin de comprendre les effets qu'il produit dans les processus de subjectivation.
Le maître incertain : remarques sur la figure poppérienne de l’enseignant
Authors: Firode Alain
Published: October 2020

Telle que la conçoit Karl Popper, la figure modèle de l’enseignant (idéalement représentée par le personnage mythique de Thalès) est celle d’un maître qui, loin de chercher à gagner la confiance de ses disciples, s’emploierait au contraire à susciter systématiquement leur défiance et leur résistance critique. Cette façon originale d’envisager la relation pédagogique, qui impose de traiter les élèves comme des contradicteurs potentiels et non comme des ignorants en attente d’être instruits, découle des thèses essentielles de la philosophie poppérienne (le « rationalisme critique »), dont elle manifeste l’inspiration radicalement anti-autoritaire.
Débriefer l’activité des élèves : une étude conversationnelle et didactique du débriefing de type corrigé des activités expérimentales lors de l’enseignement de la chimie en seconde
Authors: Khanfour-Armalé Rita , Le Maréchal Jean François
Published: October 2020

Cet article se centre sur le débriefing par l’enseignant de l’activité expérimentale des élèves en chimie en seconde. L'enjeu principal de ce moment particulier de l’enseignement est que l’enseignant structure les connaissances mises en jeu par les élèves lors de leurs activités. L’approche méthodologique utilisée articule l’analyse conversationnelle et l’analyse du savoir dans les interactions aux moyens de la méthode des facettes de connaissances. L’étude conversationnelle et didactique des débriefings de type corrigés révèle la structure essentiellement ternaire des échanges (question de l’enseignant, réponse de l’élève, évaluation de l’enseignant). Lors d’une discussion de classe, cette structure ternaire instaure et limite la portée didactique. Cette étude de cas permet de suggérer des modifications pour les débriefings de type corrigé afin que l’enseignant puisse en tenir compte dans ses préparations.
Développement durable, postures et responsabilité sociale des chercheurs en éducation
Authors: Barthes Angela , Lange Jean-Marc
Published: October 2020

L’article pose le contexte de la construction curriculaire des « éducations à » en émergence depuis les années 80 en France au travers de celle, révélatrice, de l’éducation au développement durable (EDD). En nous appuyant sur un nombre significatif de travaux de recherche en EDD réalisés en France, nous établissons une typologie des postures de chercheurs impliqués dans ces travaux. Cette typologie est construite à partir d’une méthodologie basée sur les fréquences d’occurrences lexicales sur un corpus bibliographique couplée à une méthodologie des représentations sociales des chercheurs de cette communauté. Six postures émergent, que nous avons nommées « les acceptants », « les descripteurs/prescripteurs de nouvelles procédures », « les systémiques », « les controverses », « les critiques », « les didactiques ». Nous postulons que ces postures influent sur les constructions curriculaires et posons le problème de la responsabilité sociale des chercheurs en éducation face aux injonctions politiques internationales.
L’inclusion scolaire des élèves en situation de handicap au Burundi : ressources et obstacles du point de vue des acteurs du système éducatif
Authors: Ndikumasabo Josias , Evin Agathe , Saury Jacques
Published: October 2020

La présente étude, exploratoire et compréhensive, permet d’appréhender la question des ressources et obstacles à la mise en œuvre de la politique d’inclusion scolaire au Burundi, considérée du point de vue d’un ensemble d’acteurs directement impliqués dans celle-ci. L’étude a été conduite en référence à la théorie « ancrée » (Strauss & Corbin, 1990). Les résultats révèlent quatre obstacles majeurs : les limites des possibilités d’accueil du système éducatif burundais ; l’inadéquation des pratiques pédagogiques au regard des besoins des élèves en situation de handicap ; les limites de la politique gouvernementale burundaise à mettre en œuvre le droit à l’éducation, et enfin les représentations et croyances stigmatisantes à l’encontre des enfants en situation de handicap dans la société burundaise. Ces résultats mettent aussi en évidence deux ressources évoquées par les participants : diverses initiatives éducatives favorisant l’inclusion et certains vecteurs favorables à la mise en œuvre d’une pédagogie inclusive. Les participants suggèrent, en outre, un ensemble de conditions associées à la réussite d’une éducation inclusive en termes de ressources humaines et d’environnement scolaire, qui seraient requises pour la mise en œuvre d’une réelle éducation inclusive dans ce pays.
Development and Testing of an Unmanned Surface Towing System for Autonomous Transport of Multiple Heterogeneous Underwater Vehicles for Seafloor Survey
Authors: Ohki Takeshi , Kakami Hitoshi , Nishida Yuya , Nakatani Takeshi , Thornton Blair
Published: October 2020

AbstractSimultaneous operation of multiple autonomous underwater vehicles (AUVs) can increase seafloor mapping efficiency. However, AUVs typically rely on support vessels with an operations crew for transport to sites of interest and supervision during their dives. This is
costly and limits the scalability of AUV-based seafloor mapping. This paper describes a robotic system that can transport AUVs from shore and deploy them in a survey area located offshore, without the need for a crewed support vessel. We clarify the functional requirements for ship-free AUV
operations and propose a concept that allows a single autonomous surface vehicle (ASV) to transport, release, and monitor multiple large and heterogeneous AUVs. The proposed system uses towing modules that can be connected in parallel and can accommodate a variety of pre-existing ASVs and
AUVs. A full-scale system was developed and tested during sea trials in the Mediterranean Sea off Greece, to verify basic functionality and gather data on the impact of towing multiple AUVs on ASV endurance and range. Results of these trials and lessons learned are discussed.
Resident Subsea Robotic Systems: A Review
Authors: Song Zhuoyuan , Marburg Aaron , Manalang Dana
Published: October 2020

AbstractRecent years have seen growing interest within the offshore technology sector in subsea vehicles designed for deployment not from a manned surface ship but autonomously from offshore infrastructure. While diverse in morphology and proposed concepts of operations,
all such vehicles leverage the ability to remain resident at a site of interest to offer novel operational capabilities and reduce the reliance on manned surface ships for offshore intervention. This article considers the core design properties and motivations of resident underwater
vehicles, both as expressed by the nascent commercial systems as well as the current state in academic research and noncommercial research and development (R&D). The goal is to provide a comprehensive, although nonexhaustive, review of the current resident underwater vehicle systems, core
challenges in successful system deployment, and the recent development and opportunities in resident autonomy.
A spotlight on the surfacing of self-management of employees with diabetes seen by professional nurses in selected occupational health clinics in Cape Town
Authors: Copeling Natalie , Jooste Karien
Published: October 2020

Background: Diabetes is considered one of the largest global health challenges of this century and one of the top 10 causes of death across the world. Studies indicate an increased economic burden in relation to diabetes, not only on government revenue but also within private industries. Exploring the perceptions of employees with diabetes mellitus as related to their self-management practices could assist in encouraging behaviours that are associated with positive management outcomes.Aim: The purpose of this study was to explore and describe the perceptions of employees with diabetes mellitus, seen by professional nurses in selected occupational health clinics, about the self-management of their disease.Methods: A qualitative, exploratory, descriptive contextual design was followed through 17 individual interviews with 17 employees working in various industries in Cape Town, using a semi-structured interview schedule. Open coding of the data followed, and four themes emerged. Measures to ensure trustworthiness were also adhered to in the study, and approval for the study was granted.Results: The study findings gave insight into the manner in which employees perceived their behaviour changes in terms of their self-management practices. Various emotions were expressed by employees relating to the disease as well as the lifestyle adaptations required for self-management thereof. Employees noted that knowledge acquisition and greater understanding of the motivators for lifestyle changes could improve aspects of their day-to-day living as well as the disease outcomes.Conclusion: Employees expressed an awareness of the changes and lifestyle adaptations needed but found aspects thereof to be an ongoing challenge. The areas of challenge varied amongst employees. A consciousness of the possible consequences of poor self-management practices and self-modification behavior to address these was observed.
The symbolic meaning of the number of days mentioned in the book of Jonah
Authors: Schäder Jo-Marí
Published: October 2020

The book of Jonah uses four indications of time: (1) Jonah spends 3 days and three nights in the fish; (2) the city of Nineveh takes 3 days to cross; (3) Jonah enters the city to the extent or distance of one day’s travel; and (4) Jonah proclaims to Nineveh that she has 40 days to repent. In this article it will be pointed out that each of the four instances where time is mentioned in the book of Jonah has a symbolic meaning and intends to mean more than is evident on the surface of the text.Contribution: This article contributes to the ongoing critical scholarship of the book of Jonah. In this article the interpretation of time in relation to the number of days mentioned in the book of Jonah is revisited and it is argued that the days should be understood symbolically and not literally. An evaluation is also given of what their meanings are.
A brave one-legged general: The story of Mau Mau General, Kassam Gichimu Njogu
Authors: Gathogo Julius M.
Published: October 2020

This article sets out to demonstrate the role of the ‘one-legged devil’ (as the colonialists called Patrick Gichimu Njogu), also called General Kassam. Kassam was one of the pioneer generals of the Mau Mau, a guerrilla movement that operated from the central Kenya forests as they participated in the war of liberation from the early 1950s to the early 1960s. Was Kassam a one-legged general from the word go? Methodologically speaking, the article is partially based on interviews conducted with the general before his death at the age of 89 in 2011. Being an insider, Kassam helped to give an in-depth understanding of the Mau Mau war of independence by relating the role of the Kavirondo people of western Kenya in Mau Mau historiography. Were they enticed by the colonial government to abandon the idea of the armed struggle as a way of writing off colonialism? Or did the Kavirondo (western Kenya) embrace the theology of non-violence (and pacifism) and eventually left the central Kenya group to battle it alone? Or were the people of western Kenya dissuaded to take part in the struggle by the Christian ‘gospel of love’ that abhorred violence, leading to abandoning their colleagues from central Kenya at the last minute? Theoretically speaking, the article is largely informed by John Walton’s theory of reluctant rebels. Walton argues that rebels are always incited by the leading elites in a society that undergoes war or civil war at any given time in history.Contribution: The article contributes to growing knowledge by discussing the Mau-Mau Movement in Kenya’s quest for freedom, from the 1950s to early 1960s, to demonstrate the religious role of armed conflicts in Africa. In this case, General Kassam, a baptised Anglican Christian, whose loyalty to the ancestral pantheons drove him to the quasi-religious war of independence, is the key subject in this article. In this war of independence in Kenya, a seeming conflict between African religion and Christian religion appears as a key emerging issue. The article is relevant to the HTS Journal and the world of scholarship because it is a theo-anthropocentric piece of work which deals with God, creation, and inevitable human conflicts – all of which have answers before God.

Risking health for rental housing: Reviewing service access in the informal backyard rental sector
Authors: Lategan Louis G. , Erasmus Shayne , Zietsman Markus , Cilliers Elizelle J. , Wolf Mario , Springer Christian A.
Published: October 2020

Informal backyard rentals (IBRs) constitute South Africa’s fastest growing housing subsector, flourishing within a relative research vacuum and without national policy intervention to address the vulnerabilities of stakeholders to the health risks potentially presented. This article reviewed the literature on IBRs, focussing on past policies and interventions, general characteristics, infrastructure and service access to inform an analysis of potential health risks from the existing literature to guide future research and policy-making. Research followed a qualitative approach to review IBR literature dating after 2004. Relevant publications were identified from bibliographic databases using Boolean search logic and by reviewing citations in and later citations of these publications. Relevant secondary sources were also included. The review evidenced that IBRs have received increasing policy, but limited research attention, and that health hazards have been particularly neglected. Although issues such as shared water and sanitation, inappropriate waste disposal, poor hygiene practices, high densities and poor quality structures have been referenced extensively – alluding to risks and health concerns – few studies have focussed directly on health, risk and vulnerability. The risk analysis completed based on the literature made potential risks explicit, exemplified by references to specific conditions, such as HIV/AIDS, tuberculosis and the coronavirus pandemic, demonstrating pathogenic pathways, contamination and transmission risks conducive to poor health, infection and potential disaster. The review captured and updated the contemporary literature on IBRs, with the subsequent analysis providing a platform for future empirical research on health, infrastructure and IBRs to address potential risks towards positive change in future policies.
Cognitive intelligence, emotional intelligence and personality types as predictors of job performance: Exploring a model for personnel selection
Authors: Dhliwayo Pfungwa , Coetzee Melinde
Published: October 2020

Orientation: The process of personnel selection is essential for organisations because it ensures that only those candidates who are likely to contribute to the economic value of an organisation are chosen to fill job vacancies.Research purpose: This research sought to explore cognitive intelligence (CI), ability emotional intelligence (ability EI), trait emotional intelligence (trait EI) and personality types as predictors of job performance with the view to propose a valid selection model for the Zimbabwean organisational context.Motivation for the study: In the personnel selection context, separate studies investigated the single predictive power of the constructs relevant to the study in different settings and studies. The role of personality types in selection is especially under-researched.Research approach, design and method: The study utilised a cross-sectional survey design. The convenience sample constituted (N = 299) supervisory and professionally qualified, experienced specialists from various organisations in Zimbabwe. The GAMA, AES, WEIS, MBTI, Form M and JPS were administered.Main findings: Structural equation modelling indicated CI as the best predictor of job performance, followed by ability EI and then by personality types. Trait EI could not account for any variance in job performance.Practical implications/managerial implications: Personnel selection models in the Zimbabwean context could consider including the empirically demonstrated variables in selection practices.Contribution/value-add: The research advanced personnel selection theory by empirically and scientifically identifying the core elements of, and proposing a personnel selection model for use by human resources practitioners and organisations in the African context.
Current state of the literature on mental health in Liberia: A systematic review
Authors: Hook Kimberly , Ando Kanako , Ghebrehiwet Senait , Harris Benjamin , Ojediran Babawale , Syeda Haniya , Henderson David , Borba Christina
Published: October 2020

Background: The Republic of Liberia recently experienced several events that resulted in wide-ranging societal impacts, including long-term civil war and an outbreak of Ebola. These types of events are linked to higher prevalence of mental disorders and psychosocial distress. As a result, it is likely that there is an increased prevalence of mental health disorders in the population.Aim: To assess and review the recent mental health literature in order to provide insight into existing mental health needs and effective or recommended interventions in post-conflict Liberia.Setting: Articles included in this study enrolled Liberians living in Liberia.Methods: A search of four databases was conducted for studies of any type that assessed mental health in Liberia between 01 January 2003 and 27 March 2019. After reviewing 363 articles, 21 articles were included in the final analysis. Articles were coded to identify common themes and needs.Results: The majority of studies used qualitative designs and were conducted in Monrovia, the capital city of Liberia. Common topics included adolescent mental health, intervention and assessment and post-conflict impacts. One article focused on mental health impacts after recovery from Ebola.Conclusion: Overall, there is a dearth of mental health literature that focuses on Liberia. This suggests ample opportunity for researchers to investigate mental health needs amongst the Liberian population and effective psychiatric interventions. Existing recommendations often focus on addressing adolescent health needs, including substance use practices. Opportunities for future research particularly related to needs of adult populations and to mental health impacts of Ebola, abound.
Suicide risk of male State patients with antisocial personality traits
Authors: Bosman Hendrik S. , Janse van Rensburg Charl , Lippi Gian
Published: October 2020

Background: Suicide mortality rates are higher in people with personality disorders, especially those who have antisocial personality traits. These mortality rates are also higher in people who have committed offences. Antisocial personality traits are very common in populations who have committed offences and in forensic psychiatric patients.Aim: To determine if male State patients with antisocial personality traits had a higher risk of suicide compared with patients with no antisocial personality traits. We tried to identify other risk factors for attempted suicide in this population.Setting: Weskoppies Hospital’s Forensic Unit, Pretoria, South Africa.Methods: Of the 275 male State patients, 37 had antisocial personality traits and were included in the study. Of the remaining State patients, we randomly selected 37 control group participants, who had no antisocial personality traits. For each participant, we completed a data capturing sheet and a Beck’s Suicide Ideation Scale (BSIS). We compared suicide risk and associated factors between study and control group participants.Results: Study group and control group participants had the same current suicide risk. Overall, 63 participants (85.14%) had no current suicide risk. Of the 11 (14.86%) remaining participants with current suicide risk, 5 had antisocial personality traits. Eighteen had previous suicide attempts, 13 of whom had antisocial personality traits.Conclusion: State patients with and without antisocial personality traits had similar current suicide risk. Although antisocial personality disorder is an identified risk factor for suicide, it was not the case in this study. Assessment of other risk factors for suicide should be prioritised.
Towards understanding theological positions informing migrant ministries
Authors: Magezi Vhumani , Magezi Christopher
Published: October 2020

Christian practical ministry should be driven by a thorough theological framework. Theological theory informs ministerial practices. To understand some theology driven (theologies driving) actions, it is imperative to conduct empirical studies to discern some grassroots theologies held by church leaders on the frontline of ministry. With migration as a challenge of our times that requires churches to intervene, the question that emerges is: what are the theological views and perspectives held by church leaders that drive migrants’ ministry? In answering this question, this article presents empirical findings of a study conducted in South Africa’s province of Gauteng. To locate the study within a South African context, the article devotes a substantial section on migration in South Africa. The findings revealed diversity in theological views and perspectives as well as limitations on critical biblical and theological understanding on migrant ministry as a holistic ministry. In their reflections, some church leaders showed superficial understanding of the Biblical texts, lacked contextual understanding of texts and their theology was not well thought out and integrated into the broader biblical and theological understanding.Intradisciplinary and/or interdisciplinary implications: The study integrates systematic theology, biblical texts and practical theology in discerning emerging theological views and perspectives amongst church leaders. The study contributes to gaining insight into underlying theologies that motivate migrant ministry interventions.

A Straight-Forward Method of Moments Procedure to Solve the Time Domain Integral Equation Applicable to PEC Bodies via Triangular Patch Modeling
Authors: Rao Sadasiva
Published: October 2020

In this work, a simple and straight-forward method of moments solution (MOM) procedure is presented to obtain the induced current distribution on an arbitrarily-shaped conducting body illuminated by a Gaussian plane wave directly in the time domain using a patch modeling approach. The method presented in this work, besides being stable, is also capable of handling multiple excitation pulses of varying frequency content incident from different directions in a trivial manner. The method utilizes standard Rao-Wilton-Glisson (RWG) functions and simple triangular functions for the space and time variables, respectively, for both expansion and testing. The method adopts conventional MOM and requires no further manipulation invariably needed in standard time-marching methods. The moment matrix generated via this scheme is a block-wise Toeplitz matrix and, hence, the solution is extremely efficient. The method is validated by comparing the results with the data obtained from the frequency domain solution. Several simple and complex numerical results are presented to validate the procedure.
Comprehensively Efficient Analysis of Nonlinear Wire Scatterers Considering Lossy Ground and Multi-tone Excitations
Authors: Bahrami Amir , Ostadzadeh Saeed
Published: October 2020

In this paper based on intelligent water drops algorithm (IWD), comprehensively nonlinear analysis of nonlinearly loaded wire scatterers are carried out. The analyses involve two stages. First, the problem is modeled as a nonlinear multi-port equivalent circuit and it is then reformulated into an optimization problem which is solved by the IWD. The simulation results are compared with harmonic balance (HB), arithmetic operator method (AOM), approximate methods and experiment. Analysis of the problem under strongly nonlinear loads, presence of lossy ground, multi-port structures, and multi-ton excitations are included to cover all the complex aspects. In one hand, the proposed modeling approach is in excellent agreement with other conventional techniques. On the other hand, the run time is considerably reduced.
A Compact Eight-port CPW-fed UWB MIMO Antenna with Band-notched Characteristic
Authors: Chen Li-Yan , Zhou Wei-Si , Hong Jing-Song , Amin Muhammad
Published: October 2020

A compact eight-port coplanar waveguide (CPW)-fed ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna with band-notched characteristics in a small size of 54×54×0.8 mm3 is proposed in this paper. The eight-port MIMO antenna consists of four two-port MIMO antennas. For each two-port MIMO antenna, two monopole antenna elements are printed on the FR4 substrate and placed perpendicularly to each other. To increase impedance bandwidth and improve the isolation, a stub is positioned in the middle of two radiating elements. The band-notched characteristic are achieved by etching two L-shaped resonator slots on each radiating elements, respectively. The S11 reflection coefficients, coupling isolation, radiation patterns, peak gain and radiation efficiencies of the MIMO antenna are measured. The MIMO performance of the proposed antenna is analyzed and evaluated by the envelope correlation coefficient (ECC) and total active reflection coefficient (TARC).

Authors: Priya Anumuthu , Mohideen S. Kaja , Saravanan Manavalan
Published: October 2020

A single fed circularly polarized reconfigurable patch antenna is proposed. The antenna consists of a radiating patch incorporated with an H-shaped slot at its center. Four ultra-miniature switches are used for polarization reconfiguration. The antenna is designed to operate at the center frequency of 2.357 GHz. The antenna achieves either left-hand polarization or right-hand polarization depending upon switching of corresponding switches. The antenna parameters are simulated using Ansoft high-frequency structure simulator and are validated using an Agilent network analyzer (N9925A) and antenna test systems. The antenna achieves a good impedance match of 120MHz between 2.26GHz – 2.38GHz band and achieves low cross-polarization isolation of -22.82 dB for RHCP and -21.77 dB for LHCP configurations at its operating frequency. The antenna finds application in areas of modern wireless communication.
Slot Filling Factor Calculation and Electromagnetic Performance of Single Phase Electrically Excited Flux Switching Motors
Authors: Khan Bakhtiar , Khan Faisal , Ullah Wasiq , Umair Muhammad , Hussain Shahid
Published: October 2020

For variable speed applications, flux controlling capability of electrically excited flux switching motors (EEFSMs) attract researchers’ attention. However, low copper slot filling factor of the EEFSM with standard stator slot vitiates the electromagnetic performance and efficiency. This paper has proposed a new Octane Modular Stator (OMS) EEFSM model that has pentagonal stator slot and high copper slot filling factor. Copper slot filling factor is deliberated analytically for the proposed model and designs with standard stator slots, i.e., trapezoidal and rectangular. Electromagnetic performance of the OMS, Rectangular Stator Slot (RSS) and Trapezoidal Stator Slot (TSS) EEFSM designs are evaluated by finite element analysis (FEA) through JMAG v18.1 FEA solver. The proposed OMS EEFSM model has 9% higher copper slot filling factor in comparison with standard stator slots designs under same geometric parameters. The high copper slot filling factor of the proposed OMS EEFSM model has improved performance in term of low electric and magnetic loading.

Published: October 2020

This letter presents a new compact multi-mode filtering power divider (FPD) design based on co-shared FPD topology with sharp frequency selectivity, improved out-of-band harmonic rejection and port-to-port isolation. Power splitting and quasi-elliptic filtering functions are achieved by masterly integrating only one triple-mode resonator. By loading different open-circuited stubs at the input/output ports, multiple additional transmission zeros (TZs) are generated at both lower and upper stopband, resulting in an improved stopband performance. Meanwhile, a better port-to-port isolation is obtained by adopting frequency-dependent resistor-capacitor parallel isolation network. The proposed multi-mode FPD design stands out from those in the literature by both nice operation performance and compact topology with only one resonator. For demonstration purposes, one triple-mode FPD prototype and its improved one are implemented, respectively. Measured results exhibit the superiority of the FPD design.
Scattering Characteristic Extraction and Recovery for Multiple Targets Based on Time Frequency Analysis
Authors: Liu Xiangwei , Li Jianzhou , Zhu Yi , Zhang Shengjun
Published: October 2020

The multi-target scattering field consists of the scattering fields of each target, but it is difficult to know the scattering characteristics of the specific target from the total scattering field. However, the scattering characteristics of single target embedded in the total scattered field have important research significance for target recognition and detection. In this paper, a method is proposed to extract and recover each target’s scattering characteristics from the total scattering field of multiple targets. The theoretical basis of the method is that the scattering echoes corresponding to different targets reach the receiver at different time. We acquire the total scattering field at first. Then, we perform the signal processing with time-frequency analysis to obtain the arrival time of different scattering echoes. According to the time slot difference, the time domain signal of each target can be extracted to recover its scattering field. Several examples validate the proposed method.
Wideband Microstrip Patch Antennas with Transverse Electric Modes
Authors: Mitha Tanzeela , Pour Maria
Published: October 2020

A wideband microstrip patch antenna, exciting the fundamental transverse electric (TE) mode, is investigated. The excitation of the TE mode is facilitated through replacing both of the patch and ground plane of a conventional microstrip antenna with artificial magnetic conductors (AMC), consisting of unipolar compact photonic bandgap (UC-PBG) unit cells. The AMC patch and the ground plane of this antenna behave as magnetic conductors within the bandgap region of the unit cells. Similar to conventional patch antennas, it is shown that by cutting a U-shaped slot in the AMC patch, wideband characteristics are realized. The antenna shows a 40% impedance bandwidth and operates at the TE10 mode. Moreover, the width of the patch is 1.75 times smaller than its length, reducing the overall size of the antenna by about 60%, compared with the conventional U-slot PEC antenna supporting the transverse magnetic (TM) mode.

Abstract

Objective: To study the frequency and diversity of fungi involved in onychomycosis.

Method: The cross-sectional study was conducted from February 2018 to February 2019 at the Department of Microbiology, Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre, Karachi, and the University of Karachi. Specimens were taken from patients suffering with onychomycosis attending the Dermatology Department of Jinnah Postgraduate Medical Centre and were processed for the isolation of fungi. Specimens were processed for the diagnosis by potassium hydroxide mount for microscopic evaluation and mycological culture to determine the type of fungus involved in onychomycosis. Fungi were isolated using Sabouraud Dextrose Agar with antibiotics cycloheximide and chloramphenicol, and without antibiotics. Plates were observed for the growth periodically until 4th week. Appearance of any colony was studied further for identification on the basis of cultural characteristics and microscopy. Precise identification of Candida species was done.

Results: Of the 230 samples, 85(36.96%) were from males and 145(63.04%) from females. Potassium hydroxide mount showed fungal element in 134(58.26%) specimens, while in 111(48.26%) patients the fungal culture was positive. Nine (3.9%) cases were culture-positive but potassium hydroxide-negative, while among the 134(58.26%) potassium hydroxide-positive cases, 32(23.9%) were culture-negative.

Published: October 2020

Abstract

The case of a 69-year-old man with bilateral synchronous tonsillar carcinoma is reported. The patient complained of nasal closure, strange voice, and discomfort in his pharynx when he was admitted to the Department of Otolaryngology Head and Neck Surgery at Wakayama Medical University, Wakayama, Japan, in March 2017. The palatine tonsils were enlarged and the surface was irregular. Left cervical lymphadenopathy was also evident. Histological examination from both tonsils was performed and bilateral tonsillar squamous cell carcinoma was diagnosed. PCR analysis showed the same HPV-DNA pattern from bilateral tonsils.

Concurrent chemoradiotherapy was performed. Total 70 Gy of irradiation (2Gy/day×35 day) was applied to bilateral tonsillar tumours and upper neck. Follow up was conducted every three months and the patient was free of recurrence for three years. Patient’s informed consent was taken to publish the case report.
