CHANG-ES. XVII. Hα Imaging of Nearby Edge-on Galaxies, New SFRs, and an Extreme Star Formation Region—Data Release 2
Authors: Vargas Carlos J. , Walterbos René A. M. , Rand Richard J. , Stil Jeroen , Krause Marita , Li Jiang-Tao , Irwin Judith , Dettmar Ralf-Jürgen
Published: August 2019

We present new narrow-band Hα imaging for 24 nearby edge-on galaxies in the Continuum Halos in Nearby Galaxies—an EVLA Survey (CHANG-ES). We use the images in conjunction with the Wide-field Infrared Survey Explorer 22 μm imaging of the sample to estimate improved star formation rates (SFRs) using the updated recipe from Vargas et al. We explore correlations between the updated star formation properties and radio continuum scale heights, scale lengths, and diameters, measured in Krause et al. We find a newly discovered correlation between SFR and radio scale height that did not exist using mid-infrared (IR) only SFR calibrations. This implies that a mid-IR extinction correction should be applied to SFR calibrations when used in edge-on galaxies, due to attenuation by dust. The updated SFR values also show newly discovered correlations with radio scale length and radio diameter, implying that the previously measured relationship between radio scale height and radio diameter originates from star formation within the disk. We also identify a region of star formation located at extreme distance from the disk of NGC 4157, possibly ionized by a single O5.5 V star. This region is spatially coincident with an extended ultraviolet disk feature, as traced by the Galaxy Evolution Explorer near-ultraviolet imaging. We theorize that the star formation feature arose due to gravitational instability within gas from an accretion event. New Hα images from this work can be found at the CHANG-ES data release website, https://www.queensu.ca/changes.
Direct Estimates of the Solar Coronal Magnetic Field Using Contemporaneous Extreme-ultraviolet, Radio, and White-light Observations
Authors: Kumari Anshu , Ramesh R. , Kathiravan C. , Wang T. J. , Gopalswamy N.
Published: August 2019

We report a solar coronal split-band type II radio burst that was observed on 2016 March 16 with the Gauribidanur Radio Spectro-Polarimeter in the frequency range ≈90–50 MHz, and the Gauribidanur RadioheliograPH at two discrete frequencies, viz. 80 and 53.3 MHz. Observations around the same epoch in extreme ultraviolet (EUV) and white light show that the above burst was associated with a flux-rope structure and a coronal mass ejection (CME), respectively. The combined height–time plot generated using EUV, radio, and white-light data suggests that the different observed features (i.e., the flux rope, type II burst, and the CME) are all closely associated. We constructed an empirical model for the coronal electron density distribution (N

e
(r), where r is the heliocentric distance) from the above set of observations themselves and used it to estimate the coronal magnetic field strength (B) over the range of r values in which the respective events were observed. The B values are consistent with each other. They vary as B(r) = 2.61 × r
−2.21 G in the range r ≈ 1.1–2.2R
⊙. As far as we know, similar direct estimates of B in the near-Sun corona without assuming a model for N

e
(r), and by combining cotemporal set of observations in two different regions (radio and white-light) of the electromagnetic spectrum, have rarely been reported. Further, the present work is a novel attempt where the characteristics of a propagating EUV flux-rope structure, considered to be the signature of a CME close to the Sun, have been used to estimate B(r) in the corresponding distance range.
The Rate of Stellar Mass Black Hole Scattering in Galactic Nuclei
Authors: Rasskazov Alexander , Kocsis Bence
Published: August 2019

We consider a black hole (BH) density cusp in a nuclear star cluster (NSC) hosting a supermassive back hole (SMBH) at its center. Assuming the stars and BHs inside the SMBH sphere of influence are mass-segregated, we calculate the number of BHs that sink into this region under the influence of dynamical friction. We find that the total number of BHs increases significantly in this region due to this process for lower-mass SMBHs by up to a factor of 5, but there is no increase in the vicinity of the highest mass SMBHs. Due to the high BH number density in the NSC, BH–BH binaries form during close approaches due to gravitational wind (GW) emission. We update the previous estimate of O’Leary et al. for the rate of such GW capture events by estimating the

parameter where n is the number density. We find a BH merger rate for this channel to be in the range

. The total merger rate is dominated by the smallest galaxies hosting SMBHs, and the number of heaviest BHs in the NSC. It is also exponentially sensitive to the radial number density profile exponent, reaching

when the BH mass function is

or shallower, and the heaviest BH radial number density is close to

. Even if the rate is much lower than the range constrained by the current LIGO detections, the GW captures around SMBHs can be distinguished by their high eccentricity in the LIGO band.
Le tubicen d’Épigonos de Pergame : nouvelles réflexions sur un chef-d’œuvre hellénistique
Authors: Franken Norbert
Published: August 2019

D’après les sources écrites antiques, Épigonos de Pergame était le sculpteur pergaménien le plus influent de la fin du iii e  s. av. J.-C. Il est présenté comme bronzier et apparemment aussi comme sculpteur. Il a travaillé pour le compte du roi Attale I er et peut-être encore pour Eumène II. Parmi ses œuvres, encore très appréciées à l’époque impériale romaine, figure la statue d’un tubicen (joueur de trompette). L’a. examine ici pour la première fois d’une manière détaillée un petit bronze du début de l’époque impériale, découvert à Montdidier (Somme) en 1830 et acquis par le Louvre, qu’il a depuis un certain temps déjà identifié comme tubicen . La figure du tubicen s’inspire d’un modèle hellénistique offrant plusieurs angles de vue et pourrait représenter une réplique en format réduit du tubicen d’Épigonos de Pergame, qui appartenait vraisemblablement à la scène de combat contre les Gaulois (galatomachie) de la grande donation attalide.
Nouveau Management Public, tensions de rôle et stress professionnel chez les cadres de santé
Authors: Rivière Audrey , Commeiras Nathalie , Loubès Anne
Published: August 2019

Depuis quelques décennies, la gestion des organisations hospitalières n’a cessé d’évoluer pour faire face, entre autres, à une crise de moyens humains et financiers. Ces changements ont eu des conséquences notamment sur le rôle des acteurs du soin. L’objectif de cet article est d’analyser les relations entre la perception des changements liés au Nouveau Management Public, les tensions de rôle perçues par les cadres de santé et leurs incidences sur le stress professionnel, en mobilisant la théorie des rôles et le modèle de Demerouti et al . (2001). Afin d’apporter des éléments de réponse, une étude empirique a été menée auprès de 445 cadres de santé d’établissements publics de santé français. Les résultats de la recherche indiquent que la perception des changements liés au Nouveau Management Public favorise dégressivement le conflit de rôle, la charge de travail quantitative, puis le conflit travail-famille. Par ailleurs, l’étude permet d’analyser le degré d’influence de chaque type de tensions de rôle en termes de stress au travail. Les résultats révèlent que c’est la charge de travail quantitative qui semble être le plus important prédicteur du stress professionnel des cadres de santé interrogés, alors que la charge de travail émotionnelle semble, quant à elle, diminuer le stress au travail.
La fabrique du leadership : quel rôle pour la mobilité interne ?
Authors: Morin Gabriel , Janand Anne
Published: August 2019

Si le leadership constitue une thématique récurrente dans les grandes entreprises et un champ de recherche à part entière en GRH, il n’existe cependant pas de travaux qui s’attachent à comprendre finement le rôle joué par la mobilité interne dans la fabrication de cet attribut. Cette recherche qualitative repose sur l’étude de cas de trois grands groupes internationaux et d’une institution française majeure utilisant la mobilité interne pour développer le leadership. L’apport de la recherche réside dans l’émergence d’une grille de compétences de leadership que ciblent et développent les programmes de mobilité interne. L’existence de cette grille, qui se compose de quatre compétences clés (engagement organisationnel, sens des responsabilités, plasticité sociale et self-development), pose plusieurs questions cruciales qui sont examinées. La recherche aboutit à quatre préconisations managériales sur la capacité des organisations à fabriquer du leadership en fonction de leur culture et des évolutions qu’elles veulent stimuler.
Le patrimoine et l’endettement des ménages français en 2015
Authors: Arrondel Luc , Coffinet Jérôme
Published: August 2019

Le succès du livre de Thomas Piketty en 2013, Le capital au XXI e siècle , a remis la thématique des inégalités au cœur des débats de politique économique. Par ailleurs, la crise financière de 2008 a modifié les comportements des épargnants, ces derniers privilégiant la prudence dans leur portefeuille. Les comparaisons spatio-temporelles de la distribution du patrimoine et sa composition apparaissent donc essentielles pour analyser ces questions de politique publique. À ce titre, l’enquête européenne Household Finance and Consumption Survey , qui collecte des informations sur le patrimoine, le revenu et les habitudes de consommation des ménages, semble particulièrement intéressante. Ces données permettent de comprendre les comportements d’épargne et d’endettement des ménages, d’évaluer les vulnérabilités financières et les effets de la politique monétaire. L’enquête réalisée fin 2014-début 2015 montre que la concentration des actifs financiers et professionnels des ménages français est plus importante que celle des biens immobiliers. L’épargne risquée et de long terme est davantage détenue par les plus riches mais la détention d’actions stagne à des niveaux relativement faibles. En moyenne, les ménages français déclarent posséder 268 000 euros de patrimoine brut. La moitié est endettée, en moyenne à hauteur de 37 000 euros. Le décile des Français les plus riches détient environ 46 % de la richesse totale, le centile le plus aisé, environ 15 %. La hausse de l’endettement concerne davantage les ménages aisés, disposant de capacités de remboursement plus importantes ou de patrimoines substantiels. La situation des ménages ne semble donc pas faire porter de risque majeur à la stabilité financière en France.
Vieillissement et épargne des ménages
Authors: Masson André , Touzé Vincent
Published: August 2019

Cet article s’intéresse à l’accumulation de patrimoine des ménages et à sa transformation en capital productif dans un contexte de population vieillissante. S’appuyant sur des constats négatifs réalisés à deux niveaux, d’abord microéconomique puis macroéconomique, il propose enfin un ensemble de remèdes. D’un point de vue microéconomique, la forte accumulation et concentration de patrimoine par les seniors, associée à une faible détention d’actions, s’expliquerait pour l’essentiel par de forts comportements de précaution. Pour pallier l’incertitude financière induite par l’allongement de la durée de vie (baisse du pouvoir d’achat de la pension, dépenses nouvelles en cas de dépendance, etc.), les seniors averses au risque et à l’ambiguïté adopteraient des stratégies de sur-épargne et d’investissement dans des actifs peu risqués (assurance-vie, immobilier). Le constat macroéconomique confirme la hausse historique du poids du patrimoine dans le PIB et sa faible contrepartie en actifs productifs. Il révèle aussi la baisse inquiétante du taux d’investissement net, qui apparaît corrélée à la baisse de la productivité par tête, et la dépendance accrue du financement de l’économie nationale aux investisseurs étrangers. Une série de remèdes sociaux, fiscaux, financiers et institutionnels sont avancés. Combinés les uns aux autres, ils pourraient réduire les incertitudes financières posées par l’allongement de la durée de vie, favoriser une meilleure circulation du patrimoine entre les générations et encourager l’orientation de l’épargne vers des actifs investis à long terme dans le secteur productif national.
L’inversion de la courbe des taux est-elle toujours suivie d’un ralentissement économique ?
Authors: Blot Christophe , Heyer Éric
Published: August 2019

De nombreux travaux menés sur données américaines suggèrent qu’une inversion de la courbe des taux est suivie d’une récession dans un délai moyen de 12 mois. L’aplatissement de la pente des taux observé depuis la fin de l’année 2018 aux États-Unis fait donc ressurgir les craintes d’un ralentissement brutal de l’activité. L’objectif de cet article est alors d’analyser l’information contenue dans la structure par terme des taux d’intérêt afin non seulement de vérifier la pertinence de cette relation pour les États-Unis mais aussi d’en tester la pertinence pour la France et la zone euro. Nos estimations confirment l’existence d’une relation robuste entre la pente de la courbe des taux et la croissance américaine. Les résultats montrent bien qu’une inversion de la courbe des taux accroît la probabilité que les États-Unis subissent une récession dans les mois qui suivront l’inversion. Néanmoins, relativement aux épisodes passés d’inversion de la courbe des taux, l’épisode actuel suggère un risque de récession limité. Par ailleurs, les estimations effectuées pour la France et la zone euro indiquent que l’information contenue dans la courbe des taux est beaucoup trop faible pour prévoir les récessions ou la croissance.
Effect of Decentration on the Optical Quality of Monofocal, Extended Depth of Focus, and Bifocal Intraocular Lenses
Authors: Xu Jie , Zheng Tianyu , Lu Yi
Published: August 2019

PURPOSE:

To compare the effect of intraocular lens (IOL) decentration on the optical quality in patients with implantation of three IOLs: monofocal, extended depth of focus (EDOF), and bifocal.

METHODS:

Patients had cataract surgery with implantation of one of the three above-mentioned IOLs. Higher order aberrations (HOAs), modulation transfer function (MTF), point spread function (PSF), retinal straylight, and dysphotopsia phenomena were evaluated 3 months after surgery. IOL decentration was quantified as the distance between the visual axis center and the IOL center using the OPD-Scan III aberrometer (Nidek Co., Ltd., Gamagori, Japan). The patients who received each IOL type were then divided into two subgroups (decentration of ⩽ 0.25 or > 0.25 mm) to analyze the effect of IOL decentration on these optical qualities.

RESULTS:

The study included 54 eyes (54 patients), with 18 eyes in each IOL group. The distance of IOL decentration did not differ significantly among the three groups. With a decentration of more than 0.25 mm, MTF, PSF, and coma were only significantly deteriorated in the bifocal IOL (ZMB00; Abbott Medical Optics, Santa Ana, CA). HOAs, coma, PSF, and glare perception were better in the monofocal and EDOF IOLs than those in the ZMB00 IOL when decentration was more than 0.25 mm. Furthermore, IOL decentration was significantly correlated with HOAs, coma, MTF, and PSF in the ZMB00 IOL.

CONCLUSIONS:

The monofocal and EDOF IOLs are more immune to optical quality degradation caused by IOL decentration than the ZMB00 IOL.

Spontaneous subcapsular renal haematoma is a rare condition caused by bleeding into the subcapsular or perinephric space in the absence of trauma, bleeding diathesis or anticoagulation. If the contralateral kidney is normal, radical nephrectomy is recommended due to a high incidence of small occult tumours.
A trio of multiple Wilms' tumours
Authors: Andronikou S. , Welman C. , Kader E.
Published: August 2019

Wilms' tumour is the commonest malignant abdominal tumour in children. Unilateral multicentric, and bilateral Wilms' tumours are, however, less common, occurring in 7% and 5% of cases respectively. These are often associated with sporadic aniridia, genitourinary anomalies, hemihypertrophy and nephroblastomatosis. Nephroblastomatosis is a separate entity that may act as a precursor of Wilms' tumours. We present three cases of multiple Wilms' tumours. Two cases also had nephroblastomatosis which was not seen on pre-operative CT imaging but was identified in one case at MRI. In cases of multiple Wilms' tumours, MRI provides better delineation of the tumours and may, therefore, affect management.

Abstract. Perfluoroalkyl acids (PFAAs) are a form of toxic pollutant that can be transported across the globe and accumulated in the bodies of wildlife and humans. A nationwide geographical investigation considering atmospheric PFAAs was conducted in China, which provides an excellent chance to investigate their occurences, spatial trends, and potential sources. The total concentrations of thirteen PFAAs were 6.19–292.6 pg/m3, with an average value of 39.8 ± 28.1 pg/m3, which were higher than other urban levels but lower than point source measurements. Perfluorooctanoic acid (PFOA) was the dominant PFAAs (20.6 %), followed by perfluoro–hexanoic acid (PFHxA), perfluorooctane sulfonate (PFOS), and perfluoro–heptanoic acid (PFPeA). An increasing seasonal trend of PFAAs concentrations was shown as summer
Study on Multi-Objective Optimization Design and Passive Control
of Wind Turbine Airfoil
Authors: Peng Yong , Wang Jun , Wang Wei , Yin Guoqing
Published: August 2019

Abstract. In this paper, the class-shape function transform (CST) parametric method is used to parameterize the airfoil configuration, and a new airfoil is randomly generated within a limited range. The 2D Reynolds-Averaged Navier-Stokes (RANS) computational fluid dynamics (CFD) solver is used to compute the quantities such as lift-to-drag ratio. The multi-objective genetic algorithm performs multi-objective optimization design on the airfoil plane shape to achieve high lift-to-drag ratio with low drag in operating ranges of angle of attack, and finally obtains the Pareto optimal solution set. The mixed function of index method is used to increase the thickness of the trailing edge of the airfoil. From the multi-objective solutions and blunt trailing edge solutions which represent the best trade-offs between the design objectives, one can select a set of airfoil shapes with a low relative drag force and with improved aerodynamic performance. Taking a typical airfoil NACA4418 as an example. The results show that the optimized airfoil has a better pressure distribution than the original airfoil, effectively increasing the lift coefficient and reducing the drag coefficient. After thickening the trailing edge of the optimized airfoil, the results show that the lift coefficient is improved at all angles of attack and the stall is delayed. And the blunt trailing edge airfoil has better lift-to-drag characteristics than the original airfoil and the optimized airfoil.
Influence of Extraversion on Social Loafing Behavior: A Pilot Study
Authors: Dal Nihal
Published: August 2019

The present study aimed to investigate extraversion as a moderator of social loafing on a motor task that requires fine motor skills as well as perceptual-motor skills. Participants with higher and lower levels of extraversion were asked to group dots according to their color during high and low identifiability conditions. The performance was determined by the number of dots accurately grouped. A 2 (group; high/low extraversion) × 2 (identifiability; high/low) mixed model of ANOVA revealed a significant interaction between extraversion and identifiability, which means that extraverts’ performance increased from the low to high identifiability condition. On the other hand, introverts’ performance remained relatively stable across high and low identifiability conditions. Overall, results suggested that in an identifiable state, extraverts tend to increase their performance.

Building typologies and failure modes observed in the 2015 Gorkha (Nepal) earthquake
Authors: Dizhur Dmytro , Dhakal Rajesh P. , Bothara Jitendra , Ingham Jason M.
Published: August 2019

Nepal is one of the most earthquake-prone countries in the world, and at the same time is one of the most economically deprived. On 25 April 2015 mid-western Nepal was hit by the devastating Gorkha earthquake measuring Mw 7.8 with the epicentre located 76 km north-west of Kathmandu. The earthquake was followed by a series of aftershocks, with the most significant occurring on 12 May 2015 with Mw 7.3 and an epicentre located north-east of Kathmandu. The earthquake and the associated aftershocks resulted in the destruction of half a million buildings, leaving millions of people homeless and causing a loss of more than $3.5 billion (USD) to the housing sector alone. Approximately 9,000 people were killed and over 23,000 people were injured - mostly due to damaged or collapsed buildings.

A number of documents have been published pertaining to general observations following the 2015 Gorkha earthquake and aftershocks. Here the common building typologies and related failure modes observed during inspection surveys by the authors who were part of the various reconnaissance teams following the earthquakes are summarised. A brief background on the 2015 Gorkha earthquake is provided with an outline of the tectonic environment and seismological background of Nepal and a brief summary of previous earthquake activities in the region is presented. Common construction practices identified during the reconnaissance are illustrated and briefly explained to provide context to the observed earthquake damage, with an emphasis placed on unreinforced masonry (URM) building typologies and construction practices. Comparisons between URM building damage and published macro-element failure modes are provided using various photographic and schematic examples. Commonly observed failure modes and potential causes of failure are also highlighted for buildings constructed of reinforced concrete (RC) frames with masonry infill. A brief review of adopted temporary shoring techniques is also included.

Non-destructive testing of ferromagnetic
materials using hand inductive sensor
Authors: Deyneka R. , Tykhan M. , Markina O.
Published: August 2019

Purpose: The need for reliability of industrial structures, machines and other equipment
requires more accurate testing of structural materials, especially ferromagnetic materials.
Therefore, it is important to improve existing or develop new, more accurate methods and
devices for non-destructive testing.
Design/methodology/approach: Non-destructive testing of ferromagnetic materials
is carried out by surveying a local magnetic field or determining the section magnetic
resistance of a material using the proposed new type of sensor as the hand inductive
element on a toroidal core with additional magnetic cores.
Findings: This sensor has a simple design and high response characteristic, which has
been confirmed experimentally. Such a sensor can be used for testing welded joints by the
proposed method, which is based on measuring the magnetic resistance of the welding
area.
Research limitations/implications: Analytical physical processes research that
occurred in the magnetic core material of the sensor coil core, used as a sensitive element,
is complicated by the nonlinearity of the magnetization curve of the material of the core of
the sensitive element and the lack of a single analytical relationship to fully describe the
magnetization process of ferromagnetic materials of inductive elements. Therefore, each
copy of the sensor will be an individual graduation.
Practical implications: The proposed version of the hand inductive sensor allows to
perform non-destructive testing during the operation of ferromagnetic structures and
without special requirements to external conditions with low costs and the possibility of
computer processing of data.
Originality/value: The use of the nonlinearity zone of the magnetization curve of the
inductive element core material made it possible to obtain a variant of a magnetic sensor
that is close in sensitivity to fluxgate and, at the same time, is much simpler in design using
non-deficient materials. The use of a ferrite core with low saturation induction requires a
small circuit supply voltage, but a generator power reserve. The proposed hand inductive
sensor is sensitive to the presence of extraneous ferromagnetic objects, and responds
only to a magnetic field. The high magnetic resistance of the inductive sensor allows it to be used on uneven and dirty surfaces. High sensitivity allows to detect small deviations of
the magnetic fields of dispersion of a welded joint with their comparison along the entire
joint length. All of this gave new opportunities for more accurate non-destructive testing of
structural elements and materials.

Doenças renais crônicas surgem a partir de patologias agudas ou intermitentes não tratadas adequadamente como a doença de lesão mı́nima (DLM) e a glomeruloesclerose segmentar e focal (GESF). Identificar corre- tamente essas duas doenças é de suma importância, pois seus tratamentos e prognósticos são diferentes. Dessa forma, propomos um método capaz de dife- renciar DLM e GESF através de imagens de exames patológicos. No método proposto, foram extraı́das 10240 caracterı́sticas de três redes neurais convo- lucionais pré-treinadas, foram selecionadas 62 delas através do algoritmo de informação mútua e o Random Forest foi utilizado para a classificação. O método obteve acurácia de 93,33% e Kappa de 85,47%, o que é considerado “Quase Perfeito”.

A dor lombar é uma razão comum para visitas clı́nicas e o exame de ressonância magnética é frequentemente utilizado em sistemas de apoio a di- agnóstico de patologias na coluna. Visando aprimorar e automatizar esse pro- cesso, este estudo propõe o uso de técnicas computacionais para a segmentação de vértebras em imagens de ressonância magnética, com o objetivo de realizar posteriores análises acerca de patologias na coluna. Para este fim, são utili- zadas duas arquiteturas de Deep Learning: a U-Net para a segmentação em 3D e a Deep Belief Network para a classificação de vértebras que apresen- tam ruptura ou não. Os resultados obtidos mostram que a U-Net é promissora em localizar a região da vértebra, obtendo um valor de Coeficiente de Dice médio de 89,51%, superando assim vários trabalhos importantes focados no problema. A classificação também se mostrou eficiente, com valores de 94,38% para acurácia e 88,8% de sensibilidade.

Published: August 2019

An eating disorder is a disturb characterized by an atypical eating behavior. The most common strategy for treatment is CBT, and its limitations have shown to be overcome using virtual reality approaches. Most VR envi- ronments created for this purpose reproduce tasks for treatment of body image disturbances and food avoidance. This work presents a new approach for eating disorders treatment using VR and concepts of serious games and gamification, which have been shown of promising potential in health context due to its ad- vantages when compared to other approaches. Tests assessing the usability and sense of presence in the virtual environment were applied to a group of 10 par- ticipants, indicating that the environment is well suited for medical treatment.

Published: August 2019

Este artigo descreve uma metodologia para auxiliar na identificação da paralisia do sexto nervo utilizando vı́deos. Uma vez que os métodos usu- ais para diagnóstico dessa paralisia são invasivos ou caros, um método não invasivo e acessı́vel pode ser útil para apoiar ou guiar o diagnóstico do oftal- mologista. O método proposto neste trabalho usa a rede neural convolucional YOLO para detectar a região dos olhos em faces e a curvatura de Isophotes para encontrar o centro dos olhos em cada quadro do vı́deo, mantendo assim um registro do movimento dos olhos durante um perı́odo de tempo, a fim de calcular a velocidade média com que cada olho se move. Os resultados obtidos mostraram que um olho que tem paralisia se move em média de forma 42% mais lenta que um olho saudável.

Published: August 2019

Cianobactérias são organismos que podem ocorrer em reservatórios e mananciais. Algumas espécies podem produzir toxinas, nocivas por contato ou ingestão, podendo causar até morte. A lei exige análises periódicas da água destinada à população, para monitorar e controlar a qualidade. O processo de identificação e contagem das células de cianobactérias é custoso e manual. A inteligência artificial é atuante na resolução de problemas, e as redes neurais convolucionais são o estado da arte no reconhecimento de imagens e objetos. Propõe-se desenvolver um método automático para a identificação e contagem de células de cianobactérias. Testes demonstraram a factibilidade da proposta, bem como apontaram melhorias a serem feitas.

O glaucoma é uma doença silenciosa que pode levar a cegueira caso diagnosticado tardiamente. Métodos de inteligência computacional tem sido propostos com a finalidade de disponibilizar um diagnóstico computadorizado que possa guiar o paciente para o tratamento apropriado. Todavia, essas técnicas esbarram no problema de otimização de metodologia, que depende da escolha de diversos algoritmos de diferentes áreas de conhecimento. Este trabalho propõe uma solução através da meta aprendizagem de métodos de pré processamento, decomposição e extração de caracterı́sticas que devem ser usa- dos de maneira eficiente para solucionar o problema. Os resultados obtidos são promissores, atingindo 91,24% de acurácia após 50 testes e supostamente deve melhorar proporcionalmente à quantidade de testes executados.

Published: August 2019

A hemiparesia resultante de um Acidente Vascular Cerebral (AVC) pode afetar as atividades de vida diária dos pacientes. Neste estudo foi desenvolvido um sistema biomédico (SB) baseado em Jogos Sérios (JS) para avaliação e reabilitação motora em hemiparéticos por AVC, a partir da proposta de um modelo conceitual para desenvolvimento de sistemas de reabilitação pós-AVC com base na pontuação do jogo. Foram realizados dois estudos experimentais com 22 pacientes e os resultados mostraram melhora significativa em todas as variáveis clínicas analisadas. As correlações encontradas entre a pontuação dos JS e as escalas de avaliação clínica indicam o potencial do SB como uma ferramenta de avaliação clínica.

Glaucoma é uma doença que danifica o nervo óptico. Ela é consi- derada a segunda principal causa de cegueira no mundo. Vários sistemas de diagnóstico automático têm sido propostos. No entanto, esses sistemas não fo- ram capazes de lidar com uma grande diversidade de imagens. Portanto, tais métodos não são viáveis para uso em programas de triagem. Realizamos um ex- tenso estudo para definir o melhor conjunto de atributos para a representação da imagem. No total, avaliamos 16.469 caracterı́sticas. Nossa abordagem de detecção de glaucoma usa descritores de textura e Redes Neurais Convolucio- nais (CNNs). Avaliamos nossa proposta em um total de 873 imagens de quatro bancos de dados públicos e concluı́mos que a junção da GLCM e CNNs pré- treinadas juntamente com o uso do classificador Random Forest são promisso- res na detecção desta patologia, obtendo uma acurácia de 93,35% e um ı́ndice Kappa considerado Excelente.
