Published: September 2020

El objetivo del presente trabajo es implementar un proyecto de innovación interdisciplinar de contenidos de Física en las clases de Educación Física (EF) mediante aplicaciones móviles (e.g., Wikiloc, Cinemática, Runtastic y Coach’s Eye). Para comprobar el grado de adecuación y aplicabilidad de esta propuesta se evaluó la percepción del alumnado y el profesorado de EF y Física con respecto a dimensiones de motivación, utilidad, asentamiento de conocimientos y nexo entre Física y EF. Esta propuesta se realizó en un grupo de 28 alumnos/as de 4º de la ESO y se evaluó la percepción de tres profesores/as de EF y otros tres de Física. Los resultados mostraron que la propuesta fue percibida como altamente motivante, útil, que permite el asentamiento de conocimientos y ayuda a establecer un nexo entre las áreas de EF y Física por los tres agentes implicados en el proyecto (i.e., profesorado de EF, profesorado de Física y alumnado). Se concluye que el proyecto de innovación propuesto es innovador y que ha producido un cambio de mentalidad en el profesorado de cara a la implementación de proyectos similares de cara al próximo curso académico. Por tanto, el profesorado de ambas áreas de otros centros podría considerar la implementación de proyectos similares dados los resultados favorables obtenidos.Abstract: The objective of this innovation project is to implement an interdisciplinary innovation project of physics contents in Physical Education lessons (PE) by means of mobile applications (e.g., Wikiloc, Kinematics, Runtastic, and Coach’s Eye). In order to corroborate the degree of adaptation and applicability of this innovation, students', PE, and Physics teachers' perceptions regarding dimensions of motivation, usefulness, settling of knowledge, and the nexus between physics and PE were assessed. This proposal was realised in a 28-student group from the 4th grade of ESO, as well as the perception of three PE teachers and other three of physics was evaluated. The results showed the present proposal was perceived as highly motivating, useful, that allows the settling of knowledge and helps establishing a link between PE and Physics in the three agents involved in the project (PE and Physics teachers, and students). As a conclusion, the proposed project is innovative and has led to a change of mentality of teachers towards the implementation of similar projects during the following academic year. Therefore, teachers of both areas in other centres could consider the implementation of similar projects as the results obtained are favourable.

Primaria. Un total de 114 niños y niñas de 3º y 4º de E. Primaria de escuelas públicas Manuel Pérez, Las Viñas y Reyes Católicos se ofrecieron a participar en el estudio. La AF fue determinada a través del cuestionario PAQ-A, la adherencia a la DM se determinó mediante cuestionario KIDMED, el comportamiento a través del SDQ-Cas, y la CV con el Kidscreen-27. Se observó la misma práctica de AF en niños y en niñas. Los niños mostraron más hiperactividad y las niñas una mayor conducta prosocial. La alta AF se relacionó significativamente con CV pero no con las capacidades y dificultades ni con la DM. Por último, el análisis de regresión lineal multivariado mostró que una alta AF y la DM se asociaron con el bienestar físico y el entorno escolar. Las capacidades y dificultades se asociaron con las dimensiones del bienestar físico, psicológico, entorno escolar y amigos/social. Finalmente, una alta AF y las capacidades y dificultades estuvieron de igual modo asociadas con la CV global.Abstract. The present study had the aim of determining the practice of physical activity (PA), the adherence to  the Mediterranean Diet (MD), strengths and difficulties, and quality of life (QoL) by gender and level of PA of the subjects, as well as the association of the independent variables of our study (PA, adherence to MD, and  behaviours) with QoL in students of the second cycle of Primary Educaction. A total of 114 children from 3rd and 4th grade of Primary Education at the public schools Manuel Pérez, Las Viñas, and Reyes Católicos, voluntarily participated in the study. PA was analysed through the PAQ-A questionnaire, adherence to MD was analysed through the KIDMED questionnaire, behaviours through the SDQ-Cas, and QoL through Kidscreen-27. The same levels of PA were observed in boys and girls. Boys showed more hyperactivity and girls showed higher prosocial conducts. High PA was significantly related with QoL but not with strengths and difficulties or with MD. Finally, based on a multivariate linear regression analysis, high PA and MD were associated with physical well-being and the school environment. Strengths and difficulties were associated with physical and psychological well-being, school environment, and friends/social. Also, high PA and strengths and difficulties were associated with global QoL.

ABSTRACT
Moringa oleifera meal can serve as a natural antimicrobial agent and a feed supplement supplying nutrients for rural and commercial poultry. Recently Moringa have wide range of application as a medicine, protein supplement and as an antioxidant in poultry. Moringa mainly composed of carbohydrates (38%), 27%, protein (27%), moisture (6%) and fibre (18%). The present study was planned to check efficacy of Moringa oleifera leaf meal (MOLM) for immunomodulatory effects in Broilers whilst it has been established already that there isn’t any deleterious effect in M. oleifera which are found in chemical drugs. 144 birds were divided into 4 groups having 12 birds of each and subdivided into groups of 12. Such that treatment groups were D; receiving 0%, divided into replicates D1, D2, D3 while similar divisions of group A, B and C received 2, 4 and 6 % of MOLM infused in their feed as an additive supplement. The birds were slaughtered at 14th, 21th and 35th day and blood as well as serum was collected for the sake of hematological parameters and to check the antibody titre using HA/HI checking for effectiveness of immune system at producing antibodies against Newcastle Disease, which the birds were vaccinated against. Maximum weight gain was observed in broilers fed diet B while lowest weight gain was observed in birds fed diet D, which was a control group. Maximum feed intake was observed in broilers fed diet A while lowest feed intake was observed in birds fed diet D, which was a control group. Significantly, better feed conversion ratio was observed in birds fed diet B whereas the highest feed conversion ratio (FCR) was observed in broilers fed diet without Moringa oleifera supplementations. The highest antibody level was found in the birds of group B, while lowest level was found in the broilers of group D. Maximum spleen weight was observed in birds fed diet group C and D while lowest weight was observed in birds fed diet A. Maximum thymus weight was observed in birds fed diet B and C. Bursa weight was observed in birds fed diet A and D while lowest weight was observed in birds fed diet C. There was no significant difference (P>0.05) on hematological profile among groups. All the collected data was analyzed by statistical software Minitab Inc. 2010. Minitab Statistical Software (Release 17). State College, PA. The data thus, obtained was subjected to CRD for analysis of variance. It was concluded that Moringa infused in feed does enhance immune parameters of broilers, making them better at combating diseases, making Moringa a viable dietary supplement for commercial poultry. It was also found that the optimal dose of Moringa in MOLM is 4g/kg feed

This article discusses Facial Skin Health as seen from Antioxidant Facial Scrub from Red Dragon Fruit Extract. One way to treat your face is to use a scrub. Giving a natural facial scrub has many benefits, including refreshing, repairing and firming facial skin. Antioxidants contained in red dragon fruit include betalains which function to inhibit the growth of bad cholesterol and flavonoids which are related to brain health and reduce the risk of heart disease. Scrub functions to remove dead skin cells on the surface of the body's skin which is rough and dull. In addition, it also functions to help speed up the turnover of new, clean and healthy body skin cells. Dragon fruit face scrub can also smooth the skin. Rough skin is usually caused by a build-up of dead skin cells. The content of vitamin C, protein and folic acid is said to be effective in removing these dead skin cells.

Abstract. Nitrate, sulfate and ammonium (NSA) are the main secondary inorganic aerosols of PM2.5 and play an important role in air pollution. In this study, a 3-year observational experiment was conducted from 1 January 2015 to 31 December 2017, in Chengdu, southwest China. NSA pollution characteristics, chemical conversion generation, emission reduction control sensitivity and pollutant regional transport characteristics were analyzed. NSA are the most important chemical compositions of particles with aerodynamic equivalent diameter ≤2.5 µm in ambient air (PM2.5), and the contribution of nitrate to the accumulation of PM2.5 concentration is greater than that of sulfate and ammonium. NSA also have obvious characteristics of annual, monthly, seasonal, diurnal and weekly variations. Through observation data and model simulation, it was also found that the existence of an aerosol aqueous environment plays an important role in the formation and existence of NSA. Sensitivity analysis between NSA found that controlling NO3- and SO42- plays an important role in reducing the contribution of NSA to PM2.5, which also implies that the current control of NOx and SO2 is important for improving air pollution. Combined with meteorological conditions and potential source contribution function (PSCF) analysis, local emissions and regional emissions of pollutants are found to have important impacts on Chengdu's atmospheric environment. This research result not only provides an assessment of the current atmospheric emission reduction effect but also provides an important reference for atmospheric pollution control.

Abstract. Short-lived highly reactive atmospheric species, such as organic peroxy radicals (RO2) and stabilized Criegee intermediates (SCIs), play an important role in controlling the oxidative removal and transformation of many natural and anthropogenic trace gases in the atmosphere. Direct speciated measurements of these components are extremely helpful for understanding their atmospheric fate and impact. We describe the development of an online method for measurements of SCIs and RO2 in laboratory experiments using chemical derivatization and spin trapping techniques combined with H3O+ and NH4+ chemical ionization mass spectrometry (CIMS). Using chemical derivatization agents with low proton affinity, such as electron-poor carbonyls, we scavenge all SCIs produced from a wide range of alkenes without depleting CIMS reagent ions. Comparison between our measurements and results from numeric modelling, using a modified version of the Master Chemical Mechanism, shows that the method can be used for quantification of SCIs in laboratory experiments with detection limit of 1.4 × 107 molecule cm-3 for 30 s integration time with the instrumentation used in this study. We show that spin traps are highly reactive towards atmospheric radicals and form stable adducts with them by studying the gas-phase kinetics of their reaction with hydroxyl radical (OH). We also demonstrate that spin trap adducts with SCIs and RO2 can be simultaneously probed and quantified under laboratory conditions with detection limit of 1.6 × 108 molecule cm-3 for 30  s integration time for RO2 species with the instrumentation used in this study. Spin trapping prevents radical secondary reactions and cycling, which ensures that measurements are not biased by chemical interferences, and can be implemented for detecting RO2 species in the ambient atmosphere.

Published: September 2020

Abstract. Computer microtomography (µXCT) represents a powerful tool for investigating the physical properties of porous rocks. While calculated porosities determined by this method typically match experimental measurements, computed permeabilities are often overestimated by more than one order of magnitude. This effect increases towards smaller pore sizes, as shown in this study, in which nanostructural features related to clay minerals reduce the permeability of tight reservoir sandstone samples. FIB-SEM tomography was applied to determine the permeability effects of illites at the nanometre scale and Navier-Stokes-equations were applied to calculate the permeability of these domains. With this data, microporous domains (porous voxels) were defined using microtomography images of a tight reservoir sample. The distribution of these domains could be extrapolated by calibration against size distributions measured in FIB-SEM images. For this, we assumed a mean permeability for the dominant clay mineral (illite) in the rock and assigned it to the microporous domains within the structure. The results prove the applicability of our novel approach by combining FIB-SEM with X-ray tomographic rock core scans to achieve a good correspondence between measured and simulated permeabilities. This methodology results in a more accurate representation of reservoir rock permeability in comparison to that estimated purely based on µXCT images.
Chaucer's Fantasy of Pity
Authors: Irvin Matthew W.
Published: September 2020

In his term pitee, Chaucer develops in the Knight's Tale a concept that draws upon Seneca's De clementia and Statius's Thebiad. In his version, he conflates pity's role as a virtue of sovereignty (in acts of clemency and mercy in judgment) with its affective forms (compassion and sympathy). Chaucer emphasizes a vulnerability common to all, but also uses the resulting fellow-feeling to shore up patriarchal sovereign power. Principally, Chaucer produces through his concept of pitee a male fantasy of female resistance to patriarchy: rather than depicting the political collective action (and just violence) of the Amazons in Boccaccio's Teseida, the Knight's Tale limits female resistance to a non-violent desire for autonomy, a female subjectivity that men can appropriate emotionally through shared feeling, but that does not threaten patriarchy. By both engaging and shaping readers' affectivity, Chaucer obscures with seemingly universal emotions the justice of collective female resistance to masculine domination.
“Yup, So-Jeer”: Interlanguage and Ruptured Translation in Charles Dickens and Wilkie Collins'sThe Perils of Certain English Prisoners
Authors: Nielsen Jacob Kurt
Published: September 2020

Coauthored by Charles Dickens and Wilkie Collins, The Perils of Certain English Prisoners is a tale of linguistic subversion in colonial spaces. Christian George King demonstrates a linguistic phenomenon called interlanguage, or a quasi-language that partially resembles both English and his native language. King's interlanguage disrupts the linguistic hierarchy of the tale by opening possibilities for miscommunication. To combat this linguistic tension, colonists must rely on translation—specifically, on the mistaken belief that all non-English languages, including an interlanguage, can be translated perfectly into English. Yet the very notion that meaning can be perfectly translated is shattered by interlanguage's ability to cultivate both intimacy and resistance in the translator—intimacy, because the colonizers see enough of their own language in the learner to lull themselves into thinking that meaning is transparent; and resistance, because the foreign parts of the learner's speech that remain serve as a continual reminder of the unconquered tongue. While interlanguage is most apparent in King's speech, it is also present in the construction and coauthorship of “The Perils” itself. Indeed, interlanguage proves a useful concept for thinking about any textual moment in which individual voices combine into a hybrid voice that cultivates the illusion of cohesion.

In this paper we introduce the idea of a pentual which is a 5-player extension of the well-known idea of a duel. We find the elimination probabilities of players under the assumption that each player tries to eliminate the strongest survivor at every stage. We focus mainly on the winning probability of the strongest player among the five and show that in many plausible situations this player does not even have a 20% chance of winning the game.
Comment la ponctuation se développe-t-elle chez les élèves? Une revue systématique des recherches empiriques en classe de français langue d’enseignement

Comment la ponctuation dans les textes des élèves du primaire et du secondaire se développe-t-elle? Par exemple, dans quel ordre les différents signes appa-raissent-ils maitrisés dans les productions écrites (en l’absence d’une intervention didactique particulière)? La revue systématique des recherches empiriques proposée ici recense 15 études portant sur le déve-loppement de la ponctuation chez les élèves du pri-maire et du secondaire (6 à 17 ans) en classe de fran-çais langue d’enseignement. Ces études sont rappor-tées de manière à établir trois grands stades d’acquisition. Dans la discussion, nous évoquons les modèles théoriques sous-jacents aux études recen-sées et dégageons d’autres variables, en dehors de l’âge ou du niveau scolaire, qui pourraient agir sur l’emploi des signes de ponctuation. Nous relevons enfin la nécessité de conduire davantage de re-cherches empiriques ciblant les effets d’interventions didactiques en classe susceptibles d’optimiser l’apprentissage de la ponctuation et l’utilisation adéquate des signes dans les textes.

En este artículo se presenta un estudio de caso con el que se indaga en el proceso de escritura desencade-nado por la lectura de fuentes de documentación diversas. Para llevar a cabo la investigación, se im-plementa en un aula de secundaria una secuencia didáctica basada en la modalidad de escritura coope-rativa. Mediante el análisis de las interacciones de los equipos de trabajo (hablar para escribir y actividad metalingüística) y de los diferentes textos produci-dos, se determina la incidencia de las regulaciones externas en la calidad del proceso de escritura y de los productos textuales. Los resultados evidencian lo que de positivo para el aprendizaje lingüístico apor-tan las tareas complejas y contextualizadas que combinan la lectura y la escritura y que se apoyan en la colaboración. Además, sugieren la necesidad de más investigación para explorar qué tipo de inter-venciones y de acompañamiento pueden contribuir a la construcción de un saber gramatical que redunde en un beneficio para la escritura.
Decálogo da escola como espaço de proteção social: consolidando a função social da escola como espaço democratizante
Authors: Santos Émina Márcia Nery dos , Lima Francisco Willams Campos , Vale Cassio
Published: September 2020

Neste artigo, sistematizo elementos estruturantes da escola como ambiente que se consolida como espaço de proteção, relevando que, somente em um espaço no qual se valoriza a diversidade como condição de se constituir como formativo, pode-se empoderar crianças e adolescentes, transformando-os em sujeitos de direitos e protagonistas de sua própria história. O texto objetiva reafirmar a premissa de se educar em Direitos Humanos, como condição para o fortalecimento de relações sociais democráticas, fundamento que ressignifica a função social da escola. Neste aspecto, ao se firmar como espaço institucional onde se formam valores para a convivência democrática a partir dos Direitos Humanos, o ambiente escolar se referencia como lugar educativo e não somente como o lugar instrutivo e o faz potencializando culturas, recriando e reposicionando saberes, encorajando posições políticas plurais, efetivando direitos, respeitando o estranho, ampliando acidadania e valorizando cada um e cada uma a partir de seus interesses, desejos e necessidades. Defendo, portanto, a tese, a partir da realização desse estudo bibliográfico, em torno da qual a escola, como instituição política e contraditória, pode se assentar como um lugar privilegiado para toda essa complexa formação, consubstanciando valores que possibilitem a legitimação de outro papel social para essa instituição, contrariando o paradigma racional atual de educação ameaçadora da emergência do sujeito, com todo o seu potencial criativo.
Air quality as a factor affecting urban tourism
Authors: Łapko Aleksandra , Strulak-Wójcikiewicz Roma , Panasiuk Aleksander
Published: September 2020

The purpose of the article is to determine whether potential tourists consider information about a city’s air quality in their assessment of its tourist attractiveness and how this this information affects their travel decisions. Urban tourism is a common and dynamically developing form of tourism. Cities encourage tourists to visit them with various attractions, cultural, gastronomic and accommodation offerings as well as mass events. At the same time, they are often industrial centres and important transportation hubs, which makes them characterized by a high degree of air pollution. The article presents results of a survey involving 509 respondents from Poland. The data were used to assessment to what extent information about air quality in a given city is relevant for people planning a tourist trip. In addition, the survey provided information about factors that could increase the respondents’ interest in the level of air quality in a city they were planning to visit. Particular attention was paid to the respondents’ health. Many diseases can be the result of air pollution, or can be aggravated by substances contained in smog. Therefore, the authors tried to determine whether people suffering from such illnesses were more likely to pay special attention to air quality in their prospective destinations. The results constitute a significant contribution to the knowledge about the factors affecting demand in urban tourism. They may be relevant for entities responsible for managing cities and promoting tourism products. The article also draws attention to the fact that problems arising from air pollution in cities can affect not only their residents, but also tourists.
Review of research methods for evaluating passenger level of service at airports
Authors: Szymczak Robert
Published: September 2020

The passenger level of service is a qualitative measure used to relate the quality of passenger services provided by the airport. The level of service can be perceived in correlation with both quantified and unquantified service characteristics. The global IATA Level of Service (LoS) standards are based on the maximum queuing time and space required per passenger for various terminal sub-systems. The provided level of service by the airport influences passenger experience and therefore is an important factor of airport attractiveness for airlines. The level of service is correlated with terminal facilities size so it is necessary to take it into account when designing new airports. Decrease of the LoS below acceptable standard is a trigger for operational and physical improvements of existing processes. Moreover defining the target level of service is necessary to determine terminal capacity and set coordination parameters. This paper discusses the importance of level of service at airport passenger terminals and presents methods for LoS assessment. Advantages and disadvantages were identified of each level of service research: manual observation, automatic detection, calculation and simulation. The paper includes recommendations for evaluating level of service during airport planning and operations phase.

Authors: Cunha Kaique Matheus R. , Gomes Alan Keller
Published: September 2020

Funcionalidades que permitem a interação entre usuários dentro das Redes Sociais Online configuram práticas de sociabilidade em rede, ou seja, ações como Publicar, Comentar, Curtir e Compartilhar têm um significado especial quando estão sob o foco da Sociologia Digital. Com o apoio da teoria de Pierre Bourdieu, neste trabalho são identificados e capturados dados relacionados às práticas de sociabilidade em rede dentro de Páginas Institucionais no Facebook. Esses dados são utilizados no aprendizado da sequência de ações. A partir da frequência de ocorrências das sequências aprendidas, um indicador do Capital Social acumulado é apresentado. A partir desse indicador e do número de interações sociais, o volume de Capital Social é computado.
Preprocessing Rules for Target Set Selection in Complex Networks
Authors: Melo Renato Silva , Vignatti André Luís
Published: September 2020

In the Target Set Selection (TSS) problem, we want to find the minimum set of individuals in a network to spread information across the entire network. This problem is NP-hard, so find good strategies to deal with it, even for a particular case, is something of interest. We introduce preprocessing rules that allow reducing the size of the input without losing the optimality of the solution when the input graph is a complex network. Such type of network has a set of topological properties that commonly occurs in graphs that model real systems. We present computational experiments with real-world complex networks and synthetic power law graphs. Our strategies do particularly well on graphs with power law degree distribution, such as several real-world complex networks. Such rules provide a notable reduction in the size of the problem and, consequently, gains in scalability.

Authors: Pacifico Luciano D. S. , Britto Larissa F. S. , Ludermir Teresa B.
Published: September 2020

Neste trabalho, o problema do reconhecimento automático de espécies de plantas é atacado através de técnicas de Aprendizagem de Máquina e Visão Computacional. O foco é dado para o caso específico das Plantas Medicinais, dado o potencial das mesmas como remedios naturais que previnem e tratam doenças em humanos, com baixo custo e menos efeitos colaterais (quando usadas propriamente) que remédios industrializados. Um sistema de reconhecimento de plantas e uma base de dados são desenvolvidos, baseados em características de textura e forma das folhas. Resultados experimentais indicam uma taxa de acurácia de aproximadamente 98% na base de dados proposta para os melhores classificadores selecionados.
OntoExpLine: Rumo a uma Ontologia para Representação de Linhas de Experimento Algébricas
Authors: Dias Luiz Gustavo , Lopes Bruno , De Oliveira Daniel
Published: September 2020

Workflows científicos são comumente usados como uma abstração para implementar simulações complexas de Ciência Computacional e Engenharia (CSE). Entretanto, gerenciar experimentos de CSE não é uma tarefa simples. Um mesmo experimento pode envolver a execução e a análise correlacionada de vários workflows. Conforme os experimentos se tornam mais complexos, a composição dos workflows necessita de níveis de abstrações maiores e apoio semântico. As linhas de experimentos algébricas (LinExps) são uma abordagem inovadora e promissora para modelar experimentos CSE em diferentes níveis de abstração. Apesar de representar um avanço, as LinExps ainda carecem de apoio em relação à dados do domínio do experimento e checagens automáticas para auxiliar os cientistas no processo de derivação de workflows (criar workflows executáveis a partir de uma representação abstrata). Este artigo propõe a OntoExpLine, uma ontologia de LinExp que busca oferecer maior semântica e flexibilidade ao processo de experimentação científica.

Authors: Pereira Larissa Mariany Freiberger , Pacheco Roberto Carlos dos Santos
Published: September 2020

O presente artigo buscou analisar, por meio de uma revisão, os modelos de ciclo de vida de pesquisa apresentados na literatura e universidades desenvolvidos a partir da visão de mundo da Ciência Aberta. Verificou-se que existem poucos modelos de ciclo de vida de pesquisa construídos a partir desta perspectiva e, ainda, muito limitados, uma vez que não abarcam pilares distintos sobre os quais o constructo Ciência Aberta é compreendido. Observou-se, ainda, a necessidade do desenvolvimento de ciclos de vida de pesquisa que abracem os fundamentos da Ciência Aberta para que as pesquisam sejam aderentes a este movimento.
Gerência de Dados de Proveniência Distribuídos de Experimentos Científicos: um Mapeamento Sistemático
Authors: Alves Raama Costa , Frota Yuri , De Oliveira Daniel
Published: September 2020

Experimentos científicos baseados em simulações (chamados de in silico) são fortemente dependente de recursos computacionais. Muitos experimentos são compostos de centenas ou milhares de invocações de programas. Esses experimentos comumente se beneficiam de ambientes de processamento de alto desempenho (PAD) como clusters e nuvens de computadores para acelerar sua execução. Entretanto, mesmo executando em ambientes de PAD, o volume de dados (dados de execução dos experimentos e dados de proveniência) produzido/consumido e que deve ser gerenciado, pode se tornar um gargalo. A gerência desses dados, se realizada de forma centralizada, pode impactar na análise e validação dos resultados e também no próprio desempenho da execução do experimento. Uma alternativa é armazenar e consultar esses dados de forma distribuída, o que adiciona desafios. Apesar de existirem abordagens para gerência de dados de proveniência distribuídos, não há um padrão de fato. Isso torna muito difícil correlacionar, classificar e comparar as várias abordagens existentes. Ao longo dos anos, mapeamentos sistemáticos e taxonomias foram usados para criar modelos que permitem o levantamento e a classificação de abordagens dentro de um domínio. O principal objetivo deste artigo é aplicar um mapeamento sistemático sobre a área de gerência de dados de proveniência distribuídos e propor uma taxonomia deste domínio, classificando as abordagens existentes de acordo com as classes da taxonomia

Published: September 2020

A identificação de minerais é extremamente necessária para a geologia moderna, em especial quando lidamos com métodos específicos de geocronologia e extração de informações. Contudo, este processo pode consumir um grande período de tempo devido a avaliação humana na identificação. Neste sentido, este artigo propõe a criação de uma Rede Neural Convolucional para identificação de Apatitas, Quartzos e Zircões, diminuindo assim os recursos manuais e erros nesta etapa. Além disso, testes de identificação com voluntários foram realizados, comparando os resultados obtidos por humanos e computador. Ao final, comprova-se a capacidade das Redes Neurais Convolucionais, alcançando resultados superiores aos esforços humanos e acurácia acima de 90%.
MuTARe: A Multi-Target, Adaptive Reconfigurable Architecture
Authors: Brandalero Marcelo , Carro Luigi , Beck Antonio Carlos Schneider
Published: September 2020

With recent changes in transistor scaling trends, the design of all types of processing systems has become increasingly constrained by power consumption. At the same time, driven by the needs of fast response times, many applications are migrating from the cloud to the edge, pushing for the challenge of increasing the performance of these already power-constrained devices. The key to addressing this problem is to design application-specific processors that perfectly match the application's requirements and avoid unnecessary energy consumption. However, such dedicated platforms require significant design time and are thus unable to match the pace of fast-evolving applications that are deployed in the Internet-of-Things (IoT) every day. Motivated by the need for high energy efficiency and high flexibility in hardware platforms, this thesis paves the way to a new class of low-power adaptive processors that can achieve these goals by automatically modifying their structure at run time to match different applications' resource requirements. The proposed Multi-Target Adaptive Reconfigurable Architecture (MuTARe) is based upon a Coarse-Grained Reconfigurable Architecture (CGRA) that can transparently accelerate already-deployed applications, but incorporates novel compute paradigms such as Approximate Computing (AxC) and Near-Threshold Voltage Computing (NTC) to improve its efficiency. Compared to a traditional system of heterogeneous processing cores (similar to ARM's big.LITTLE), the base MuTARe architecture can (without any change to the existing software) improve the execution time by up to $1.3\times$, adapt to the same task deadline with $1.6\times$ smaller energy consumption or adapt to the same low energy budget with $2.3\times$ better performance. When extended for AxC, MuTARe's power savings can be further improved by up to $50\%$ in error-tolerant applications, and when extended for NTC, MuTARe can save further $30\%$ energy in memory-intensive workloads.
A PatchMatch-based Approachfor Matte Propagation in Videos
Authors: Backes Marcos H. , Oliveira Neto Manuel M.
Published: September 2020

This thesis presents a temporally-coherent matte-propagation method for videos based on PatchMatch and edge-aware filtering. Given an input video and trimaps for a few frames, including the first and last, our approach generates alpha mattes for all frames of the video sequence. We also present a user scribble-based interface for video matting that takes advantage of the efficiency of our method to interactively refine the matte results. We perform quantitative comparisons against the state-of-the-art sparse-input video matting techniques and show that our method produces significantly better results according to three different metrics. We also perform qualitative comparisons against the state-of-the-art dense-input video matting techniques and show that ours produces similar quality results while requiring less than 7% of their user input.
Transfer Learning by Mapping and Revising Boosted Relational Dependency Networks
Authors: Santos Rodrigo Azevedo , Paes Aline , Zaverucha Gerson
Published: September 2020

Statistical machine learning algorithms usually assume that there is considerably-size data to train the models. However, they would fail in addressing domains where data is difficult or expensive to obtain. Transfer learning has emerged to address this problem of learning from scarce data by relying on a model learned in a source domain where data is easy to obtain to be a starting point for the target domain. On the other hand, real-world data contains objects and their relations, usually gathered from noisy environment. Finding patterns through such uncertain relational data has been the focus of the Statistical Relational Learning (SRL) area. Thus, to address domains with scarce, relational, and uncertain data, in this paper, we propose TreeBoostler, an algorithm that transfers the SRL state-of-the-art Boosted Relational Dependency Networks learned in a source domain to the target domain. TreeBoostler first finds a mapping between pairs of predicates to accommodate the additive trees into the target vocabulary. After, it employs two theory revision operators devised to handle incorrect relational regression trees aiming at improving the performance of the mapped trees. In the experiments presented in this paper, TreeBoostler has successfully transferred knowledge among several distinct domains. Moreover, it performs comparably or better than learning from scratch methods in terms of accuracy and outperforms a transfer learning approach in terms of accuracy and runtime.
