Channel Assignment (CA) in MRMC Wireless Mesh Network (WMN) is an efficient device that exploits numerous non-intersecting channels to reduce the interference and augment the capability of WMN. However, CA could diminish the complete network interference; its consequences might cause certain design issues that impact the efficiency of the network. A good CA in wireless mesh networks could minimize numerous interference co-channels and enhance the throughput. The clonal selection approach is simulated using the rudimentary notion of adaptive immune reply to virus stimulus. The PSO is inspired using the social behaviors of swarms. Motivated by these two optimization methodologies, in this paper, a hybridized particle swarm aided clonal selection approach is introduced for resolving channel assignment issue, i.e., evaluating a lower-interference channel assignment depending on gathered data. Conflict Vector in Conflict Graph known as antigens in clonal selection algorithm having fewer affinity values are improved using the particle swarm optimization update operation. Then the clonal selection and mutation operation is employed iteratively to generate the optimum conflict vectors. The experimental results are carried out using NS2. From the outcomes, it is clearly shown that the suggested approach has better energy efficiency, packet delivery ratio, and less network delay, packet drop compared to existing algorithms.

Nearly 17.5 million deaths occur due to cardiovascular diseases throughout the world. If we could create such a mechanism or system that could tell people about their heart condition based on their medical history and warn them of any risk than it could be of huge help. In our work, we will use machine learning algorithms to forecast the heart disease risk factor for a person depending upon some attributes in their medical history. The data mining technique Naive Bayes, Decision tree, Support Vector Machine, and Logistic Regression is analyzed on the Heart disease database. The accuracy of different algorithms is measured and then the algorithms are compared.

In any education system, attendance of students is the first and foremost thing. Apart from academic compulsion, it reflects trust and belongingness of the students in system. In current scenario with large number of students and modern teaching equipments, the methodology of attendance keeping and maintenance needs to be changed. Hence, we have developed a prototype system using PHP/MySQL in which attendance is marked via mobiles that use wireless LAN connectivity through Access Points. The attendances so marked are stored on to a server. From the stored data, the reports of the students (regarding status: regular, short or condone) are generated. The developed system is tested in class room environment at G.B. Pant University of Ag. & Technology during teaching and is found to be effective. This system can be easily customized as per attendance system of any other Institute/University.

Published: August 2019

The vibrational effects created by machines moving parts is strictly related with the characteristics of the law of motion they implement, both in case of cam-follower devices and in case of servo system electronic cam controls. One of the most effective way to prevent these harmful phenomena is to limit the harmonic content of the law of motion by designing their curve as a combination of few, low frequencies, sinusoidal curves, but this often makes difficult to satisfy other functional requirements like precision points or constant speed intervals. In this work an original method to solve this problem is illustrated. It adds to the programming language CamOMiLe new functions to assist the functional design of mechanisms. The combination of the classical theory results with the flexibility of CamOMiLe building block approach makes possible to address a large number of practical applications and two examples of them are illustrated.

Precise and efficacious detection of moving targets is a prominent task in on-going synthetic aperture radar (SAR) technique. The perception of moving object allows quite significant data about the situation under observation for both surveillance and intelligence activities. The task of accurately locating moving targets against strong background clutter in minimum of time is of utmost interest in the current research area. Fractional Fourier Transform (FrFT) concentrates the energy of the required chirp signal so that it can be well separated from the chirp like noise. The proposed SAR Moving Target Detection (MTD) process is based on the combination of FrFT with the adaptive-neuro fuzzy decisive technique. The correlation among the received signal and the FrFT of the received signal are computed which maximizes the required signal energy and applied to the adaptive-neuro fuzzy decisive module that detects the target location adaptively using the fuzzy linguistic rules. The simulation is performed by changing the number of targets, different Pulse repetition intervals, antenna turn velocity, iterations and the analysis is carried out based on the metrics, like detection time, missed target rate, and Mean Square Error (MSE), proving that the proposed Adaptive-Neuro Fuzzy-based MTD process detected the object in 5.0237 secs with a minimum missed target rate of 0.1210 and MSE of 23377.48.

Velocities of Flare Kernels and the Mapping Norm of Field Line Connectivity

Published: August 2019

We report on observations of flare ribbon kernels during the 2012 August 31 filament eruption. In the 1600 and 304 Å channels of the Atmospheric Imaging Assembly, flare kernels were observed to move along flare ribbons at velocities v
∥ of up to 450 km s−1. Kernel velocities were found to be roughly anticorrelated with strength of the magnetic field. An apparent slipping motion of the flare loops was observed in the 131 Å only for the slowest kernels moving through the strong-B region. In order to interpret the observed relation between B
LOS and v
∥, we examined the distribution of the norm N, a quantity closely related to the slippage velocity. We calculated the norm N of the quasi-separatrix layers (QSLs) in MHD model of a solar eruption adapted to the magnetic environment that qualitatively agrees to that of the observed event. We found that both the modeled N and velocities of kernels reach their highest values in the same weak-field regions, one located in the curved part of the ribbon hook and the other in the straight part of the conjugate ribbon located close to a parasitic polarity. Contrariwise, lower values of the kernel velocities are seen at the tip of the ribbon hook, where the modeled N is low. Because the modeled distribution of N matches the observed dynamics of kernels, this supports the notion that the kernel motions can be interpreted as a signature of QSL reconnection during the eruption.
Pickup Ions beyond the Heliopause

Published: August 2019

Fluxes of energetic neutral atoms (ENAs) with energies greater than 1 KeV measured by the Interstellar Boundary Explorer (IBEX) are predominantly created by charge exchange of interstellar neutral atoms with hot, nonthermal (pickup) ions. Since the properties of pickup ions (PUIs) depend on the place of their birth, they bear an imprint of the interaction between the solar wind (SW) and the local interstellar medium (LISM). Of special importance is a narrow “ribbon” of an enhanced ENA flux discovered by IBEX. While the origin of this ribbon is still under debate, various models attribute it to charge exchange between the LISM neutral atoms and PUIs just beyond the heliopause. In this work, we investigate the stability of PUI distributions inferred from global modeling of neutral atoms in the heliosphere using fully kinetic particle-in-cell modeling. The initial distribution consists of PUIs created from high-speed, low-temperature neutral atoms born in the supersonic SW ahead of the heliospheric termination shock (TS) and PUIs created from low-speed, high-temperature H atoms born between the TS and the heliopause. The simulations indicate that such distributions are unstable against quasi-parallel modes with fast growth timescales (of the order of one hour or less). The development of these instabilities may strongly modify the initial PUI distribution, leading, for example, to formation of a plateau in the direction parallel to the local magnetic field. These modes, however, saturate at relatively small amplitudes and do not lead to complete isotropization of the distribution on the timescales considered.
Resonant Mode Conversion of Alfvén Waves to Kinetic Alfvén Waves in an Inhomogeneous Plasma
Authors: Xiang L. , Chen L. , Wu D. J.
Published: August 2019

Kinetic Alfvén waves (KAWs) are dispersive Alfvén waves (AWs) with a perpendicular wavelength comparable to the ion (ion–acoustic) gyroradius or the electron inertial length and can play an important role in wave energy dissipation and particle energization. In this paper, we investigate the resonant mode conversion of AWs into KAWs for the case of an arbitrary angle α between the density gradient of the ambient plasma and the ambient magnetic field in an inhomogeneous two-temperature magnetoplasma. The results show that the mode conversion sensitively depends on the angle α, the density inhomogeneous gradient

, and the parallel wavenumber

, as well as the ion to electron temperature ratio

. In particular, the excited KAWs are stronger when α is closer to 90° and are hardly excited for

. Moreover, the maximal strength of the excited KAW increases with the increase of

, but decreases with the increase of

. These results are helpful for our comprehensive understanding of the resonant mode conversion of AWs into KAWs in solar magnetic atmospheres when AWs originating from the photosphere propagate along solar magnetic fields into the corona.
Analysis of Small-scale Magnetic Flux Ropes Covering the Whole Ulysses Mission

Published: August 2019

Small-scale magnetic flux ropes in the solar wind have been studied for decades via both simulation and observation. Statistical analysis utilizing various in situ spacecraft measurements is the main observational approach, which helps investigate the generation and evolution of these small-scale structures. In this study, we extend the automated detection of small-scale flux ropes based on the Grad–Shafranov reconstruction to the complete data set of in situ measurements of the Ulysses spacecraft. We first discuss the temporal variation of the bulk properties of 22,719 flux ropes found through our approach, namely, the average magnetic field and plasma parameters, etc., as functions of the heliographic latitudes and heliocentric radial distances. We then categorize all identified events into three groups based on event distributions in different latitudes separated by 30°, at different radial distances, and under different solar activities. With the detailed statistical analysis, we conclude the following: (1) the properties of flux ropes, such as the duration, scale size, etc., follow power-law distributions, but with different slope indices, especially for distributions at different radial distances. (2) They are also affected by the solar wind speed, which has different distributions under different solar activities, manifested as a latitudinal effect. (3) The main difference in flux rope properties between the low and high latitudes is attributed to possible Alfvénic structures or waves and to flux ropes with relatively high Alfvénicity. (4) Flux ropes with longer durations and larger scale sizes occur more often at larger radial distances. (5) With a stricter Walén slope threshold, more events are excluded at higher latitudes, which further reduces the latitudinal effects on flux rope properties.

Narrow-line Seyfert 1 galaxies (NLS1s) are believed to be powered by the accretion of matter onto low-mass black holes (BHs) in spiral host galaxies with BH masses M
BH ∼ 106–108
M
⊙. However, the broadband spectral energy distribution of the γ-ray-emitting NLS1s are found to be similar to flat-spectrum radio quasars. This challenges our current notion of NLS1s having low M
BH. To resolve this tension of low M
BH values in NLS1s, we fitted the observed optical spectrum of a sample of radio-loud NLS1s (RL-NLS1s), radio-quiet NLS1s (RQ-NLS1s), and radio-quiet broad-line Seyfert 1 galaxies (RQ-BLS1s) of ∼500 each with the standard Shakura–Sunyaev accretion disk (AD) model. For RL-NLS1s we found a mean log(

) of 7.98 ± 0.54. For RQ-NLS1s and RQ-BLS1s we found mean log(

) of 8.00 ± 0.43 and 7.90 ± 0.57, respectively. While the derived

values of RQ-BLS1s are similar to their virial masses, for NLS1s the derived

values are about an order of magnitude larger than their virial estimates. Our analysis thus indicates that NLS1s have M
BH similar to RQ-BLS1s and their available virial M
BH values are underestimated, influenced by their observed relatively small emission line widths. Considering Eddington ratio as an estimation of the accretion rate and using

Par-delà les cathares : conflits de pouvoir et hérésie dans le diocèse de Lucques (XII e -XIV e siècles)
Authors: Trivellone Alessia
Published: August 2019

L’hérésie médiévale est au centre d’un vaste débat historiographique de portée internationale déclenché il y a vingt ans, lorsque des publications françaises ont posé des questions brûlantes : l’hérésie médiévale a-t‑elle pu parfois être inventée par les hommes du Moyen Âge ? L’étendue des déviances doctrinales médiévales a-t‑elle pu être surestimée par les historiens qui l’ont étudiée ? La controverse s’est installée, et pour cause : les enjeux du débat ne concernent en effet pas seulement la manière d’appréhender l’hérésie médiévale, mais investissent plus largement la manière de faire l’histoire et de traiter les sources. Cet article entend proposer une réflexion méthodologique sur l’approche des sources médiévales documentant l’hérésie, à partir de l’étude des nombreuses affaires attestées dans le diocèse de Lucques, en Toscane, du xii e  au xiv e  siècle : des sources variées et parfois inédites (témoignages dans un procès, lettres pontificales, sculptures, documents inquisitoriaux) y dénoncent des hérétiques qu’elles désignent de plusieurs noms (patarins, ariens, « pauvres de Lyon »). Si l’historiographie a invariablement vu derrière ces affaires la manifestation de déviances doctrinales, qu’elle a parfois uniformisées en les désignant de « cathares », une analyse à nouveaux frais permet d’ancrer ces affaires dans des conflits politiques plus larges : il en résulte clairement que ces accusations d’« hérésie » sont bien loin de cibler des déviances doctrinales, mais se nourrissent d’enjeux sociaux et politiques.

Le rôle de l’équipe en thérapie familiale
Authors: Dupont Sébastien
Published: August 2019

Cet article revient sur un fondement de l’approche systémique : le travail en équipe. La thérapie familiale s’est en effet rapidement démarquée des autres méthodes thérapeutiques par le fait qu’elle est généralement conduite à plusieurs. Certains pionniers ont très vite considéré la pratique en équipe comme une condition indispensable de ce type de thérapie. La thérapie familiale ne se résume donc pas à la rencontre entre un thérapeute et une famille ; elle relève de la rencontre et de la coévolution entre deux groupes : une équipe et une famille. Après avoir donné une vue d’ensemble des différentes manières dont a pu être pensée cette pratique collective, l’article met en évidence les atouts mais aussi les difficultés du travail à plusieurs.
La régulation émotionnelle au cœur de la danse thérapeutique
Authors: Duriez Nathalie
Published: August 2019

Les familles arrivent en thérapie avec une chorégraphie maintes fois répétée depuis parfois plusieurs générations. Chacun se coordonne aux autres avec des comportements, des représentations et des stratégies de régulation émotionnelle (SRE) préférentiels. Dès la première séance, les familles invitent les thérapeutes à occuper une position particulière dans leur danse, selon leur histoire, leurs croyances, mais aussi selon leurs SRE (évitement, amplification, intellectualisation, réorientation de l’attention, etc.). En réponse à cette sollicitation de la famille, le thérapeute vivra des émotions qu’il régulera aussi, introduisant ainsi une différence dans l’organisation du système familial qui va complexifier la danse de la famille. La cothérapie peut permettre une meilleure conscientisation et un ajustement des SRE des thérapeutes, chacun aidant l’autre thérapeute à réguler différemment ses émotions pour mieux danser ensemble. À partir d’un extrait de séance, nous verrons comment les SRE sont déterminantes dans la danse de la famille, comment les thérapeutes entrent dans cette danse avec leurs propres SRE et comment la chorégraphie sera alors complexifiée et réorganisée.
INVESTIGATION OF HISTOGRAM EQUALIZATION FILTER FOR CT SCAN IMAGE ENHANCEMENT
Authors: Siddiqi Ayesha Amir , Narejo Ghous Bakhsh , Tariq Mashal , Hashmi Adnan
Published: August 2019

This piece of work investigates the application of histogram equalization method to clinical images for noise removal and efficient image enhancement without any information loss. Computed tomographic (CT) images of the abdomen bearing liver tumour are kept under study. Liver exhibits heterogeneous combination of intensities which makes it a challenging task to enhance the liver tumour embedded in the image. Distortion occurs due to the presence of quantum noise in the CT scans and important information of the image is suppressed. The methodology adopted in this paper comprises of two stages. Initially pixel based intensity transformation is adopted for de-noising the background of the image by the selection of appropriate threshold levels. The resultant image gives a noise free background and the foreground features are enhanced. In the next stage histogram equalization filters are applied to the transformed image. The equalization method which gives uniform image enhancement with lesser mean square error (MSE) and increased peak signal to noise ratio (PSNR) is supposed to be an effective method for efficient enhancement of the images. This study deals with the application of histogram equalization methods to CT images which can aid the radiologists for better visualization and diagnosis of the disease.

Published: August 2019

The goal of this study is to integrate individual behavior related to both reasoned action and unconscious behavior with social influence to form a theoretical model to explore continuance usage of a mobile terminal (CUMT). This study advances a model of CUMT which considers individual factors and social factors based on TRA. Perceived usefulness (PU), perceived ease of use (PEU) and habit are introduced as independent variables and social network relationships (SNR) are introduced as a moderator into the research model. 221 respondents collected in China are used to examine the hypotheses with PLS-SEM method. The results indicate that PU, PEU and habit are the determinants of CUMT, and both PU and PEU are the antecedents of habit. Moreover, the findings demonstrate that SNR has a negative moderating effect on the PEU-CUMT relationship. This study provides a comprehensive understanding of the behavior of CUMT. Theoretical contributions and practical implications are also discussed.

Authors: Bartolucci Marco , Mattioli Francesco , Batini Federico
Published: August 2019

In recent years, the authors have witnessed the rebirth of board games. This contribution aims to investigate the educational potential of non-random board games in two ways: the comparison of performances of “expert adult players” and “adult non-players” through a correlation study (n=45) and the comparison between the results achieved by a group of children after 26 hours of game training (n=10) and those of a control group that carried out traditional educational activities (n=10) by using a nonrandomized control group pretest-posttest. Specifically, the findings relating to fluid intelligence, analytical and converging cognitive processes and creativity were compared. The results suggest that non-random board games can be an important stimulus for the cognitive functions, with a particular focus on the creative side, and therefore have an important educational function.

Authors: Şahin Muhittin , Keskin Sinan , Yurdugül Halil
Published: August 2019

This study aims to analyse the psychological constructs of loneliness and family support on game addiction among children, who are a major risk group for game addiction. The study explores: a) the effect of the secondary-school students' perception of family support on game addiction; b) the mediation effect of the feeling of loneliness experienced by children in the effect of family support on game addiction; and c) the moderating effect of gender on the mediation model. The study group is composed of 575 students studying in a secondary school in the city of Ankara. For the analysis of the data, the study employed factorial and structure validity analyses, a reliability analysis, a structural equation model, and mediator and moderator variable analyses. The study concluded that although family support had a significant effect on game addiction, a major part of such effect resulted from the individual's perception of loneliness, which was more evident among the female students.
Discovering Requirements for the Technology Design to Support Disaster Resilience Analytics
Authors: Moore Kathleen , Purohit Hemant
Published: August 2019

Research on technology-assisted crisis management have been centered on tools to assist the response phase of a disaster. Through a semantic network analysis of concept relations in the titles of the publications, the authors found that many theoretical tools exist for disaster management but have not been operationalized to take a holistic approach toward technology for resilience. There is a lack of emphasis on the design of information and communication technologies, besides geographical information systems, to assist other phases of the crisis management cycle, particularly the preparedness and mitigation phases for resilience. By operationalizing the MOVE framework in a case study, the authors discover factors critical to the design of informatics and visualization tools to support resilience. This study concludes with a conceptual design framework “Digital Crow's Nest” to show feasibility of technology design for disaster resilience analytics using open data sources.

In this article, we show that building up a good “family” relationship between the franchisor and the franchisee is the real essence of franchising, and proven working knowledge is the foundation of the “family” relationship. Specifically, we discuss the process of how to make big data and business analytics meaningful for virtual communities and social networking in franchising. The process consists of business challenges, data foundation, analytics implementation, insights, execution and measurements, distributed knowledge, and innovation.

Introdução: A dependência total do idoso é uma condição que requer cuidador em tempo integral para realização das atividades básicas de vida diária e pode ocasionar modificações na dinâmica familiar. Objetivo: Analisar o funcionamento de famílias com idosos totalmente dependentes. Metodologia: Estudo descritivo, desenvolvido em Cuiabá, no Mato Grosso, com quatro famílias atendidas na Estratégia de Saúde da Família, utilizando o Modelo Calgary de Avaliação de Famílias. Os dados foram coletados nos domicílios das famílias por meio de entrevista com o cuidador principal e foram submetidos à análise de conteúdo e interpretados utilizando como referencial a categoria funcional do Modelo Calgary de Avaliação de Famílias. Resultados: Estão apresentados em três categorias: caracterização das famílias; funcionamento interno para cuidar do idoso; e funcionamento das famílias com o núcleo familiar externo. As famílias eram caracterizadas como multigeracionais, com membros consanguíneos e habitavam com os idosos. O funcionamento interno é influenciado pela dependência total dos idosos. O funcionamento das famílias com o núcleo familiar externo não é completamente efetivo por problemas na comunicação. Considerações finais: Os resultados deste estudo têm implicações para os profissionais de saúde, pois mostra aspectos do funcionamento familiar, sugerindo modos de intervir na melhora da comunicação entre seus membros.

Objetivo: Apreender a percepção da equipe de saúde frente às barreiras de comunicação e identificar fatores que contribuem ou interferem na comunicação da equipe de saúde. Método: Pesquisa qualitativa com 12 profissionais de saúde e administrativos, integrantes de uma equipe de saúde em hospital pediátrico de grande porte de Curitiba, PR. Os dados foram coletados por meio de entrevista semiestruturada e gravada. Para a análise dos dados utilizou-se a análise de conteúdo proposta por Minayo. Resultados: Os profissionais possuíam conhecimento sobre o conceito de comunicação, sobre o significado de barreiras de comunicação e as possíveis consequências. Como barreira de comunicação destacam-se a falta de comunicação, interrupção da comunicação antes que a mensagem chegasse ao destino, falta de interesse do receptor, sobrecarga de trabalho e de informações, não adequação da linguagem e problemas técnicos com o meio de comunicação utilizado. Conclusão: Uma boa comunicação é necessária para garantir que adversidades ambientais não interfiram na assistência, portanto o entendimento dos elementos que permeiam o desenvolvimento de uma comunicação eficaz é de extrema importância.

O que é a função da fala? Processo de produção de sons ou um meio de obschenie?
Authors: Michina G. A.
Published: August 2019

No presente artigo, examina-se, brevemente, a função da fala, tomando por fundamento a perspectiva histórico-cultural de L. S. Vigotski. Para esse exame, primeiramente, admite-se a fala como uma atividade. Em seguida, com base nas etapas percorridas nas investigações realizadas pela autora, argumenta-se que a fala desempenha papel central no desenvolvimento das funções psíquicas superiores, isto é, ela é tratada como um mecanismo de desenvolvimento dessas funções. Finalmente, é tecida a conclusão de que a fala possui três funções básicas, a saber, a fisiológica, a de meio de comunicação e a de meio psicológico.Palavras-chave: Perspectiva histórico-cultural.

The management dilemma: Removing elephants to save large trees
Authors: Henley Michelle D. , Cook Robin M.
Published: August 2019

The loss of large trees ( 5 m in height) in Africa’s protected areas is often attributed to the impact by savanna elephants (Loxodonta africana). Concerns have been raised over large tree mortality levels in protected areas such as South Africa’s Kruger National Park (KNP) and in the past, the need to manage its elephant population in order to preserve large trees and biodiversity as a whole. Our review aims to synthesise and discuss the complexities of managing elephants’ effects on the landscape to ensure the survival of large trees, as well as the application purposes of the various lethal and non-lethal elephant mitigation strategies. We further critically evaluate past management strategies, which have solely focused on controlling elephant numbers to protect large trees. Past mitigation strategies focused on managing elephant impact by directly reducing elephant numbers. However, maintaining elephant numbers at a pre-determined carrying capacity level did not prevent the loss of large trees. Research on large tree survival in African savannas has continually exposed the complexity of the situation, as large tree survival is influenced at various demographic stages. In some cases, a coalescence of historical factors may have resulted in what could be perceived as an aesthetically appealing savanna for managers and tourists alike. Furthermore, the past high density of surface water within the KNP homogenised elephant impact on large trees by increasing the encounter rate between elephants and large trees. Our review evaluates how current mitigation strategies have shifted from purely managing elephant numbers to managing elephant distribution across impact gradients, thereby promoting heterogeneity within the system. Additionally, we discuss each mitigation strategy’s occurrence at various landscape scales and its advantages and disadvantages when used to manage impact of elephant on large trees.Conservation implications: A variety of options exist to manage the effects that elephants have on large trees. These options range from large-scale landscape manipulation solutions to small-scale individual tree protection methods. Interactions between elephants and large trees are complex, however, and conservation managers need to consider the advantages and disadvantages of each mitigation strategy to protect large trees.
Modelling distributor performance in network marketing organisations
Authors: Msweli-Mbanga P.
Published: August 2019

This study develops a model that predicts distributor performance in network marketing organisations. Distributor performance is conceptually linked through formal hypotheses to perceptions of marketing mix, organisational commitment, job satisfaction and customer profile. Data was gathered from 500 network marketing distributors to test two nested models, one with job satisfaction as a determinant of performance, and the other with performance as a determinant of job satisfaction. The findings revealed that there was greater model parsimony when the causal direction of the performance/job satisfaction relationship was such that performance causes job satisfaction. The results support several of the a priori hypotheses and suggest that the perceptions of the marketing mix variable are not directly linked to performance, but that the relationship between the variables is mediated by the organisational commitment variable. Implications of the study to network marketing practitioners and avenues for further research are provided.
