Data-Driven Trend Forecasting in Stock Market Using Machine Learning Techniques
Authors: Misra Puneet , Chaurasia Siddharth
Published: October 2019

Stock market movements are affected by numerous factors making it one of the most challenging problems for forecasting. This article attempts to predict the direction of movement of stock and stock indices. The study uses three classifiers - Artificial Neural Network, Random Forest and Support Vector Machine with four different representation of inputs. First representation uses raw data (open, high, low, close and volume), The second uses ten features in the form of technical indicators generated by use of technical analysis. The third and fourth portrayal presents two different ways of converting the indicator data into discrete trend data. Experimental results suggest that for raw data support vector machine provides the best results. For other representations, there is no clear winner regarding models applied, but portrayal of data by the proposed approach gave best overall results for all the models and financial series. Consistency of the results highlight the importance of feature generation and right representation of dataset to machine learning techniques.
Influência da política de investimentos no desempenho econômico de empresas industriais brasileiras em períodos pré-crise e crise econômica
Authors: Pamplona Edgar , Mazzuco Miriam Aparecida Silveira , Silva Tarcísio Pedro da
Published: October 2019

As decisões de investimento estão entre as mais importantes inseridas na teoria de finanças e, devido sua complexidade, permanecem como foco de estudo em todo o mundo. Neste sentido, visando contribuir para a formação do conhecimento acerca do tema, que carece de evidências comparativas entre períodos de recessão e prosperidade, este estudo tem por objetivo verificar a influência da política de investimentos no desempenho econômico de empresas industriais brasileiras em períodos pré-crise e crise econômica.Para tanto, realizou-se pesquisa descritiva, de procedimento documental e abordagem quantitativa dos dados. A amostra de pesquisa corresponde a 123 organizações industriais brasileiras listadas na B3, sendo o período de análise de 2010 a 2015 e as informações derivadas da base de dados Economática®. Os resultados confirmam que as empresas vêm perdendo desempenho no período de crise econômica (2014 e 2015) e que as aquisições de imobilizado, vinculadas à política de investimentos, são significativamente menores nos referidos anos de recessão econômica. Quanto à influência de tais investimentos no desempenho econômico, tem-se que em períodos de prosperidade econômica as aquisições de ativos fixos proporcionam maior resultado, o que não foi confirmado estatisticamente em períodos de crise. Além disso, investimentos passados também não apresentam relação com a performance corporativa em períodos turbulentos. Conclui-se que decisões de investimentos são mais complexas e suscetíveis a não resultarem no desempenho planejado em períodos de crise, o que deve demandar, portanto, tomada de decisão ainda mais acurada por gestores para a correta efetivação dos investimentos realizados.

The pharyngeal organ is located at the crossroad of the respiratory and digestive tracts in vertebrate, and it is continuously challenged by varying Ags during breathing and feeding. In mammals, the pharyngeal mucosa (PM) is a critical first line of defense. However, the evolutionary origins and ancient roles of immune defense and microbiota homeostasis of PM are still unknown. In this study, to our knowledge, we are the first to find that diffuse MALT is present in PM of rainbow trout, an early vertebrate. Importantly, following parasitic infection, we detect that strong parasite-specific mucosal IgT and dominant proliferation of IgT+ B cell immune responses occurs in trout PM, providing, to our knowledge, the first demonstration of local mucosal Ig responses against pathogens in pharyngeal organ of a nonmammal species. Moreover, we show that the trout PM microbiota is prevalently coated with secretory IgT and, to a much lesser degree, by IgM and IgD, suggesting the key role of mucosal Igs in the immune exclusion of teleost pharyngeal bacteria. Overall, to our knowledge, our findings provide the first evidence that pharyngeal mucosal immunity appear earlier than tetrapods.
Una legge incompiuta: gli attuali disagi nelle famiglie
Authors: Gentili Paolo , Caredda Maria
Published: October 2019

L’articolo intende evidenziare il profondo cambiamento che è intervenuto nei rapporti delle famiglie con un loro membro con malattia mentale a seguito della attuazione della legge 180. Dopo una breve disamina delle situazioni familiari antecedenti alla legge e correlate alla presenza degli ospedali psichiatrici nella gestione dei malati mentali, gli Autori individuano una serie di problematiche attuali relative alla gestione, corretta e integrata, da parte delle strutture sanitarie e le criticità relative a una efficace collaborazione con le famiglie dei malati mentali. Gli A. infine prospettano tre modalità con le quali l’attuale società italiana si pone di fronte alla necessità di attuare una integrata e multidisciplinare politica di salute del malato mentale in tutte le sue accezioni bio-psico-sociale e soprattutto umano, in senso ampio. In particolare, si sottolinea il valore degli interventi di aiuto, assistenza, supporto e condivisione di interventi operati da strutture (anche ecclesiali) che pongono al centro della assistenza il malato come persona e la sua famiglia come risorsa (per una psichiatria umana). Gli A. concludono con la riflessione secondo la quale il peso che la società è disposta nel prossimo futuro a dare alle famiglie, come necessari interlocutori per l’individuazione e l’attuazione di politiche sanitarie volte al benessere globale del malato mentale, sia fortemente collegato alle modalità con cui la famiglia stessa è vista e considerata nella società. ---------- The article intends to highlight the deep change that has intervened in families-mental patient relationship after the implementation of the Law 180. After a brief discussion around the situations of the family antecedent to the law and related to the presence of psychiatric hospitals in the mental patients management, the Authors identify a series of current issues related to right and integrated management by the medical facilities and critical point related to an effective collaboration with the mental patient’s families. Finally, the A. show three modes by which the current Italian society deals with the necessity to realized an integrated and multidisplicinary health care policy for mental patient in all his meaning bio-psycho, social and above all human in a wide sense. In particular, the article highlights the value of help, care, support and cooperation from structures also ecclesial that centres care on patient as person and his family as resource (for a humane psychiatry). The A. end with the thought for which the weight that society is willing to give to the families in the next future, as necessary interlocutors for the identification and implementation of health policies aimed at the overall welfare of mental patient, is strongly connected to the modalities by which the family itself is seen and considered in the society. 1164

Trabalhadores precários no Tribunal Superior do Trabalho: salário, contrato e jornada de trabalho (Brasil, 1946-1953)
Authors: Assis Silva Alessandra Belo
Published: October 2019

Este artigo analisa os debates e sentenças do Tribunal Superior do Trabalho e demais instâncias da Justiça do Trabalho acerca da garantia de direitos para trabalhadores considerados precários e/ou informais no momento de consolidação das instituições trabalhistas no Brasil, isto é, quando sua estrutura estava exclusivamente voltada para os “trabalhadores formais”. Nesse caminho, o período investigado vai de 1946 a 1953, levando em consideração mudanças na jurisprudência, originadas na última corte da Justiça do Trabalho. Por intermédio da leitura de livros de registro dos debates e sentenças dos magistrados, as chamadas notas taquigráficas do TST, bem como por meio do uso de periódicos de jurisprudência, procuro entender qual foi o papel da Justiça do Trabalho, sobretudo do Tribunal Superior do Trabalho, no que diz respeito à proteção e garantia de direitos para o amplo grupo de trabalhadores precários no Brasil.
Análise das certificações ambientais – Estudo sobre a Certificação Fator Verde
Authors: Lima Rochelle Silveira , Rios Márcio Salomão Silva
Published: October 2019

A necessidade da preservação ambiental, hoje, é tema de preocupação mundial, fomentando discussões acerca de posturas mais sustentáveis em diversificadas áreas. Dentre essas áreas é possível destacar a Construção Civil, que, no que diz respeito ao meio ambiente, é causadora de severos impactos. Diante disso essa área encontra-se em constante mudança e buscando por métodos e tecnologias que minimizem as consequências dela. Dentre essas mudanças é importante destacar o surgimento das certificações ambientais, que consistem na avaliação quantitativa e qualitativa do desempenho das edificações quanto aos seus impactos ao meio e que são implantadas. A criação das certificações permitiu uma popularização do desenvolvimento sustentável na área de projetos e arquitetura, entretanto é uma prática que vem sedo aperfeiçoada ao longo do tempo e enfrenta muitas críticas quanto a sua adesão, eficiência e real impacto. Dessa forma, o presente trabalho realizou uma pesquisa exploratória de cunho quali-quantitativo, em fontes bibliográficas digitais e físicas, para produção do mesmo. O trabalho discorre brevemente acerca do surgimento das certificações, e o contexto do desenvolvimento sustentável na construção. Este também traz a luz os selos LEED, AQUA e Fator Verde, apresentados como referência de estudo e estabelece um sucinto comparativo entre eles, analisando as áreas que os mesmos contemplam e suas semelhanças e divergências.
A quantitative assessment of institutions of higher education disaster preparedness and resilience
Authors: Murphy, PhD, MPH, MBA Stephen A. , Brown, PhD Jeff , Shankar, PhD, MS Arti , Lichtveld, MD, MPH Maureen
Published: October 2019

Objective: Assess levels of disaster preparedness in institutions of higher education (IHEs) in the United States.Design: An anonymous, 57-question survey targeted individuals responsible for emergency management at IHEs across the US descriptive statistics and bivariate chi-square analysis were reported. Using the established threshold score of the initial Cities Readiness Initiative from the CDC, an individual respondent’s composite score of 70 percent or higher across 23 specific questions within the 57-question survey was labeled as “prepared.”Results: Chi-square analysis identified variables associated with lower preparedness levels at IHEs not achieving the minimum 70 percent score. Having a campus law enforcement officer serve the additional role of emergency manager had a negative association with being prepared [χ 2 (1) = 10.18, p < 0.001]. Having emergency management as a separate university function from campus law enforcement had a positive relationship with being prepared [χ 2 (1) = 18.55, p < 0.001]. Staffing the emergency management function with a professional having less than 3 years of emergency management experience had a negative association with being prepared.Conclusions: Our results indicate that minimizing the mission of emergency management by simply tasking a campus law enforcement officer with the extra responsibility of emergency management or entertaining less professionally qualified personnel to lead emergency management’s complex mission can lead to disastrous results. Not only is preparedness impacted, but also resilience when facing disaster situations. Our nation continues to strive to become more resilient when facing such adverse events, as formally embraced and emphasized in the 2017 National Security Strategy. Research continues to offer best practices and unfortunately continues to highlight gaps. While the higher education community is not one of the 16 federal critical infrastructure sectors, identified gaps such as those presented in our findings as well as those published by the National Academies of Sciences are cause for alarm. Not only are higher education campuses generating invaluable contributions to society in general, bio-innovation, public health, and medicine, to name a few, they are a core stakeholder in resilience research and implementation. Yet, research continues to indicate preparedness and therefore resilience gaps in this sector. The authors propose implications for practice, policy, and research to assist IHEs in achieving a more comprehensive, sustainable level of resilience.
De Nieuwe Neurofilosofie

The New Neurophilosophy: An Introduction to the ANTW special issue

Contemporary neurophilosophy is more pragmatic than the early neurophilosophy of the 1980’s. It features two implicit ideas: First, commonsense cognitive concepts (CCC’s) like ‘free will’, ‘thoughts’, ‘consciousness’, ‘attention’ and ‘self’, belong to a variety of disciplines and cannot be appropriated by either philosophy or cognitive neuroscience. Second, the description of biological processes in the brain and the description of behavioral processes by CCC’s are so far removed from each other that a simple reduction, or even a relation of implementation between them, is implausible. What is needed instead, is a relation of interpretation: which cognitive concepts should be used to describe specific brain processes is not fixed in advance but the outcome of an ongoing negotiation between common sense practice, philosophy, and cognitive neuroscience. All articles in this special issue shed light on these two key ideas that characterize a new neurophilosophy.
Quantification of toxic metallic elements using machine learning techniques and spark emission spectroscopy
Authors: Davari Seyyed Ali , Wexler Anthony S.
Published: October 2019

Abstract. The United States Environmental Protection Agency (US EPA) list of Hazardous Air Pollutants (HAPs) includes metal elements suspected or associated with development of cancer. Traditional techniques for detecting and quantifying toxic metallic elements in the atmosphere are either not real time, hindering identification of sources, or limited by instrument costs. Spark emission spectroscopy is a promising and cost effective technique that can be used for analyzing toxic metallic elements in real time. Here, we have developed a cost-effective spark emission spectroscopy system to quantify the concentration of toxic metallic elements targeted by US EPA. Specifically, Cr, Cu, Ni, and Pb solutions were diluted and deposited on the ground electrode of the spark emission system. Least Absolute Shrinkage and Selection Operator (LASSO) was optimized and employed to detect useful features from the spark-generated plasma emissions. The optimized model was able to detect atomic emission lines along with other features to build a regression model that predicts the concentration of toxic metallic elements from the observed spectra. The limits of detections (LOD) were estimated using the detected features and compared to the traditional single-feature approach. LASSO is capable of detecting highly sensitive features in the input spectrum; however for some elements the single-feature LOD marginally outperforms LASSO LOD. The combination of low cost instruments with advanced machine learning techniques for data analysis could pave the path forward for data driven solutions to costly measurements.
Imágenes públicas: cultura visual y la redefinición de la esfera pública
Authors: Martínez Luna Sergio
Published: October 2019

La expansión contemporánea de las imágenes implica cambios profundos en el concepto de la esfera pública. El artículo parte de la problemática definición del objeto de estudio de la cultura visual. La complejidad de este objeto hace que las aproximaciones provenientes de este campo de estudio queden diluidas en enfoques mediocéntricos que impiden el análisis de las transformaciones que las condiciones de la imagen contemporánea provocan en la esfera pública. Con el fin de elaborar un marco para el estudio de las articulaciones entre imagen y esfera pública, el artículo presta atención a algunos conceptos propios de la imagen y la visualidad contemporáneas como ubicuidad, pantalla, circulación, agencia o imaginación. Finalmente se propone la revisión del concepto de esfera pública entendida como móvil, interconectada y descentralizada.
Pulsión populista en el Estado Constitucional de Derecho: ¿Soberanía (ilimitada) o democracia (intangible)?
Authors: Sanz Moreno José Antonio
Published: October 2019

Hoy la democracia está enferma y, no obstante, sigue sin resolver su paradoja original. La crisis institucional y el “tiempo populista” hacen imprescindible una nueva revisión para determinar qué sea la democracia y, en su caso, cuáles los límites al poder y a su ejercicio. Ya no sirve recrearnos en esa supuesta tensión histórica entre liberalismo (constitucionalismo) y democracia (soberanía popular), representada por Mouffe como vectores diferentes e irreductibles: del lado de lo jurídico y la libertad (individual), el control del poder, las garantías de derechos humanos y la sujeción de los poderes constituidos a la ordenación constitucional; del lado de lo político y la igualación (gobernantes y gobernados), la paradoja democrática, la construcción de un pueblo y su vox populi vox dei. Pero también cabe impugnar una jurisprudencia constitucional que, a pesar de vincular rule of law y democracia, coloca al Estado social de Derecho ante su más funesta indefensión. Por todo ello, la democracia debe afrontar el vértigo de la vuelta a la exaltación de la voluntad popular ilimitada y, desde la certeza de la integración estatal en una ordenación internacional que también limita la soberanía (ius cogens), reforzar su significado constitucional e intangible.
¿Bebés o tejidos celulares? Individuación y parentesco del embrión criopreservado entre usuarios y actores de la fertilización in vitro en Ciudad de México
Authors: Olavarría Patiño María Eugenia
Published: October 2019

Con base en un estudio etnográfico llevado a cabo en Ciudad de México con personal médico de clínicas de reproducción asistida, así como entre usuarios y usuarias de fertilización in vitro (FIV), este artículo explora el entramado de relaciones en que se ubican los embriones criopreservados y vitrificados. Postula que, al crear seres inclasificables desde el punto de vista de moral y legal, las biotecnologías perturban el equilibrio de categorías preexistentes y originan otras. Explica cómo el marco legal, religioso y político que impera en México durante el periodo 2015-2017 determina que, al producto de esta tecnología, se le pueda considerar "hijo", "bebé", "no nacido" o "concebido", entre otros apelativos. El óvulo fertilizado aparece, entonces, en el discurso y en el habla bajo términos de apelación que evocan aspectos subjetivos y relacionales. El destino final del embrión su conservación, donación a la investigación su conservación, donación a la investigación científica, adopción o desecho no solo depende de su científica, adopción o desechosu conservación, donación a la investigación científica, adopción o desecho no solo depende de su no solo depende de su reconocimiento bajo alguno de esos términos, sino que, tal como estudios realizados en Francia (Giraud, 2014) y Estados Unidos (Collard y Kashmeri, 2009; Cromer, 2018) plantean, otros parámetros intervienen, como la edad, el sexo, la situación financiera o de salud de los padres o propietarios. El presente estudio va más allá al sugerir que el lugar de los embriones en la genealogía tanto como la experiencia previa de los padres o propietarios en ciclos de FIV son factores definitorios en la personificación y en el establecimiento de lazos de parentesco.
Políticas Públicas de Economia Solidária: uma Revisão da Literatura
Authors: Ferreira Fernanda Machado , Lombardi Leandro , Severino Maico Roris , Carvalho Claudia Regina Rosal , Campos Flávia Rezende
Published: October 2019

A Economia Solidária é um movimento que cresce no Brasil como forma de inclusão social e geração de renda. No entanto, esse tipo de economia ainda carece de mecanismos de apoio e consolidação de políticas públicas para o fortalecimento dessas práticas. Desse modo, o objetivo desse estudo foi realizar uma revisão da literatura da produção de estudos científicos sobre políticas públicas de economia solidária a fim de verificar quais as políticas públicas foram criadas no âmbito federal, estadual e municipal para fomentar a Economia Solidária. Para tanto, foi realizado um levantamento bibliográfico com o propósito exploratório e descritivo, considerando uma abordagem qualitativa dos estudos científicos analisados. Os resultados obtidos demonstram que ações políticas de fomento a esse tipo de economia têm abrangência nas três esferas governamentais e vem conseguindo apoio crescente dos governos. Esses avanços são essenciais para a consolidação da economia solidária como estratégia e política de desenvolvimento.
Comparação entre três sistemas de notação da configuração de mão com base em dados da Libras
Authors: Alecrim Elisane Conceição , Xavier André Nogueira
Published: October 2019

A configuração de mão é um dos parâmetros articulatórios com base no qual os sinais podem ser analisados. Ela se refere, especificamente, aos diferentes estados das juntas dos dedos, potencialmente distintivos, mas também sujeitos à grande variação intra e intersujeito. Neste trabalho, são comparados três sistemas de notação propostos para esse parâmetro, o de Stokoe, o de Liddell e Johnson e o de Johnson e Liddell, com vistas a demonstrar, com base em dados da libras, que o terceiro deles é mais apropriado para a análise fonética das línguas sinalizadas. Os dados analisados se referem a uma das três produções de 26 dos 60 sinais originalmente coletados por Xavier e Barbosa (2014) de 12 sujeitos surdos (seis homens e seis mulheres) da cidade de São Paulo. O critério de seleção desses sinais foi a presença da configuração de mão em B (dedos abertos e unidos pelas laterais) e da configuração de mão em 5 (dedos abertos e espalmados). Com isso, 185 produções foram selecionadas e analisadas. Os resultados indicam que o sistema de Stokoe tem caráter mais fonológico, o de Johnson e Liddell, um caráter mais fonético e o de Liddell e Johnson, um caráter intermediário entre os dois primeiros.

Para atingir tal objetivo, foi adotada a abordagem qualitativa, de cunho exploratório, tendo como instrumento um questionário aplicado a um grupo de dez intérpretes. Foram utilizados referenciais teóricos da área dos estudos da interpretação jurídica e os resultados da pesquisa, ao evidenciarem os contextos de atuação e as dificuldades enfrentadas pelos intérpretes, podem oferecer subsídios para melhor planejamento e prática da profissionalização de intérpretes de Libras-Português que atuam no campo jurídico.
El despertar sexual de don Quijote: construcción literaria y parodia erótica en el romance de AltisidoraDon Quixote’s Sexual Awakening: Literary Construction and Erotic Parody in Altisidora’s Ballad
Authors: Zarzosa Alicia Gallego
Published: October 2019

The ballad Altisidora sings in chapter XLIV is a seduction song full of erotic references that has not been studied under this light yet. This work covers the existing literary critic about Altisidora, and then places the erotic context for the ballad within the episode of sexual harassment the damsel plays for don Quijote. The core of this work is a detailed analysis of the erotic references to the romancero, popular poetry and erotic literature in the ballad. The article shows that, beyond the literary parody, Altisidora’s ballad is the most powerful resource for the young lady to erotically siege don Quijote.
Monostatos: Racism inDie Zauberflöte
Authors: Lösel Steffen
Published: October 2019

Wolfgang Amadeus Mozart’s (1756–1791) Die Zauberflöte (libretto by Emanuel Schikaneder, 1751–1812) is one of the most popular operas in the history of the genre. And yet, for contemporary audiences, it is deeply problematic, marred by its stereotypical portrayal of the stage moor Monostatos, whom Georg Nikolaus von Nissen—second husband to Mozart’s widow Constanze—describes in his biography of the composer as a “low, cowardly slave [whose] submissive character was created in correspondence with his nation.” This article looks at Monostatos in the philosophical and social context of the eighteenth century. It argues that the role reflects the pervasive racial stereotypes of Enlightenment-era anthropology— stereotypes that were so well entrenched that the opera’s authors did not question them despite their personal acquaintance with a highly respected African living in Vienna at the time: Angelo Soliman (c. 1720/21–96).
n. 35 - NOTAS SOBRE O CAMPO DE ESTUDOS DO CURRÍCULO: CONTROVÉRSIAS CRÍTICAS E PÓS-CRÍTICAS
Authors: Barbosa Renata Peres , Bueno Sinésio Ferraz
Published: October 2019

O presente artigo tem como objetivo tensionar o debate acerca do pensamento pós-crítico no campo do currículo, problematizando e situando os limites e controvérsias do campo, enquanto subsídio teórico relevante para análise dos fundamentos e das políticas curriculares. Para tanto, no primeiro momento, apresenta-se um breve histórico dos estudos do currículo, enquanto campo de disputas, que delineia as bases para um projeto formativo que ampara as experiências escolares. Em seguida, busca-se apresentar, de modo geral, o debate pós-crítico e sua articulação com as teorias curriculares a partir de pesquisas nacionais do campo. Por fim, problematiza-se as implicações da adoção de uma perspectiva pós-crítica, buscando refletir sobre a educação e o currículo perante o quadro hegemônico do pensamento pós-crítico. Como aspectos conclusivos, inferimos que a postura cética adotada pelos enfoques pós-críticos parece-nos emboscar em uma cilada pedagógica, que impede ainda mais a apropriação dos conteúdos objetivos formativos de forma crítica, anulando as potencialidades de resistência à reificação. Trata-se de um estudo bibliográfico.

Objective: Malnutrition has been reported to be a rather common health problem in hospitalized children and it is recommended tobe evaluated in these conditions. The objective of this prospective trial was to evaluate the nutritional status of hospitalized pediatricurology patients and find the prevalence of malnutrition in this specific subgroup of patients.Patients and Methods: All subsequent children between 1 and 18 years old who were hospitalized between January 2018 and January2019 in the pediatric urology unit of a referral university hospital were included into the study. STRONGkids questionnaire was usedto assess the nutritional status of the children. Malnutrition was evaluated according to anthropometric measurements based on thecomputer programs developed by the World Health Organization (WHO).Results: A total of 76 patients were included in the study. The mean age of the patients was 8.84±4.23; mean height was 121.03±22.49cm; mean weight was 27.8±13.41 kg. Malnutrition risk, according to STRONGkids screening tool was high in 1 patient, medium in8 patients and low in 67 patients. According to anthropometric measurements, 6 patients (7.9%) and 25 patients (32.9%) had acuteand chronic malnutrition, respectively.Conclusion: The current prospective trial suggested that malnutrition is a significant issue also for hospitalized pediatric urologypatients.
Unsupervised Selective Rank Fusion on Content-Based Image Retrieval
Authors: Valem Lucas Pascotti , Pedronette Daniel Carlos Guimarães
Published: October 2019

Mainly due to the evolution of technologies to store and share images, the growth of image collections have been remarkable for years. Therefore, developing effective methods to index and retrieve such extensive available visual information is indispensable. The CBIR (Content-Based Image Retrieval) systems are one of the main solutions for image retrieval tasks. These systems are mainly supported by the use of different visual descriptors and machine learning methods. Despite the relevant advances in the area, mainly driven by deep learning technologies, accurately computing the similarity between images remains a complex task in various scenarios due to the well known semantic gap problem. As distinct features produce complementary ranking results with different effectiveness performance, a promising solution consists in combining them. However, how to decide which visual features to combine is a very challenging task. This work proposes three novel methods for selecting and combining ranked lists by estimating their effectiveness in an unsupervised way. The approaches were evaluated in five different image collections and several descriptors, achieving results comparable or superior to the state-of-the-art in most of the evaluated scenarios.
Human Activity Recognition based on Wearable Sensors using Multiscale DCNN Ensemble
Authors: Sena Jessica , Schwartz William Robson
Published: October 2019

Sensor-based Human Activity Recognition (HAR) provides valuable knowledge to many areas. Recently, wearable devices have gained space as a relevant source of data. However, there are two issues: large number of heterogeneous sensors available and the temporal nature of the sensor data. To handle these issues, we propose a multimodal approach that processes each sensor separately and, through an ensemble of Deep Convolution Neural Networks (DCNN), extracts information from multiple temporal scales of the sensor data. In this ensemble, we use a convolutional kernel with a different height for each DCNN. Considering that the number of rows in the sensor data reflects the data captured over time, each kernel height reflects a temporal scale from which we can extract patterns. Consequently, our approach is able to extract information from simple movement patterns such as a wrist twist when picking up a spoon, to complex movements such as the human gait. This multimodal and multi-temporal approach outperforms previous state-of-the-art works in seven important datasets using two different protocols. In addition, we demonstrate that the use of our proposed set of kernels improves sensor-based HAR in another multi-kernel approach, the widely employed inception network.
Multiband image classification of astronomical objects
Authors: Martinazzo Ana , Hirata Nina Sumiko Tomita
Published: October 2019

Astronomy has entered the era of large digital sky surveys, transitioning from a relatively data-scarce field of study to a very data-rich one. The images coming from these new surveys are hyperspectral (having up to a few dozen bands) and noisy (due to limitations on telescope resolution and atmospheric conditions), present faint and saturated signals, and can amount to tens of terabytes. This unique set of characteristics make them very attractive for trying out deep learning methods. In this short paper, we present a multiband image classifier for stars, galaxies and quasars, and propose steps towards a semi-supervised scheme that could enable the discovery of new objects.
Parametrização hierárquica de superfícies poligonais construída com triangulação de Delaunay restrita
Authors: Telles Pablo , Silva Romildo , Medeiros Esdras , Pesco Sinesio
Published: October 2019

As superfícies triangularizadas podem ser parametrizadas hierarquicamente possibilitando uma representação da superfície, juntamente com o seu domínio paramétrico, por níveis de detalhes e, assim, permitindo um controle melhor da parametrização. Neste artigo apresentamos uma estrutura hierárquica para superfícies triangularizadas, com a topologia de um disco, construída com uma triangulação de Delaunay restrita. Essa construção é livre de possíveis inconsistências topológicas ou na orientação das faces introduzidas na triangulação pelo processo de simplificação. Além disso, utilizamos um processo de otimização na hierarquia para reduzir as distorções causadas pela parametrização.

Multitemporal liver analysis for surgical plan and clinical follow-up, adapted for Sibgrapi 2019
Authors: dos Santos Rodrigo Braga , dos Reis Guilherme Fontes , da Costa Gilson Alexandre Ostwald Pedro
Published: October 2019

The Computed tomography (CT) images have been widely used in diagnosis of diseases, for surgical planning and transplantation. Not only targeting the relevant structures but also as the automatic volume measurement based on segmentation are a critical step for computer-aided diagnosis and surgical planning (POHLE, 2003) (F, 2002). In particular, the analysis of liver imaging obtained by CT presents some challenges. This organ presents a topographic anatomy different from the functional anatomy. This was described by Claude Couinaud (COUINAUD C.; DELMAS, 1957), from the anatomical studies that detailed the 8 functional units of the liver, known as hepatic segments.Currently the conditions of analysis of computerized tomography’s are basically visual, performing them from 2D images (R, 1999). According to (F, 2002) this ends up being a source of errors, since the expert is subjected to an exhaustive routine of analysis from avery large number of images, and the fatigue can cause errors of interpretation by human failure. In order to aid in surgical planning and clinical follow - up, an application was developed that transforms the computational tomography, previously into 2D images, into a 3D model that can be used in the web application developed in this work allowing a multitemporal analysis of the liver.

Raksts veltīts Rīgas Politehniskā institūta (RPI) direktoram (1906–1916), izcilam organizatoram, zinātnisko darbu autoram profesoram Voldemāram fon Knīrīmam (Woldemar von Knieriem; 1849–1935), kurš devis nozīmīgu ieguldījumu lauksaimniecības zinātnes attīstībā, vadījis RPI Lauksaimniecības nodaļu (1903–1906), kā arī mācību un izmēģinājumu saimniecību «Pētermuiža» (1880–1915) Olaines tuvumā. Tā kļuva par paraugsaimniecību ne tikai Baltijas reģionā, bet visā Krievijas impērijā. Studentiem viņš sniedza plašas teorētiskās un praktiskās zināšanas lauksaimniecībā, akcentējot praktiskas, zinātniski aprobētas atziņas par lauksaimniecības platību un muižu apsaimniekošanu. Profesors fon Knīrīms bija Baltijas Tehniskās augstskolas Rīgā rektors (1918), Herdera institūtā Rīgā docētājs (1921–1927). Mūža nogalē viņš dzīvoja ģimenes īpašumā Skangaļu muižā Vidzemē, uzrakstīja atmiņas par savu dzīvi un vasarās atpūtās un priecājās kopā mazbērniem, viņu vidū – vēlāko Zviedrijas premjerministru Ūlofu Palmi (Ulof Palme; 1927–1986). V. fon Knīrīms mūžībā devās 1935. gada janvārī, apbedīts Lielajos kapos Rīgā.The article is dedicated to Professor Woldemar von Knieriem (1849–1935), who has made a significant contribution to the development of agricultural science, headed the Department of Agriculture of Riga Polytechnic Institute (1903– 1906), as well as Training and Experimental Farm «Peterhof» (1880–1915) near Olaine city. It became a model farm not only in the Baltic region but also throughout the Russian Empire. Professor W. von Knieriem was the Director of RPI (1906–1916), an outstanding organizer and author of scientific works. He provided students with extensive theoretical and practical knowledge in agriculture, focusing on practical, scientifically approbated lessons about the management of agricultural land and manors and trying to raise the general level of culture and the horizons of young people. Professor W. von Knieriem was Rector of the Baltic Technical University in Riga (1918) and worked in the Herder Institute in Riga (1920–1927). He spent his last years in his family estate in Vidzeme writing memories of his life and enjoying the company of grandchildren – one of them later became Prime Minister of Sweden Ulof Palme (1927–1986). W. von Knieriem died in January 1935 and was buried in the Great Cemetery in Riga.

Published: October 2019

This study aimed at determining the educational requirement of Beekeepers in mitigating Climate Change Effects on bee honey production in Obudu Local Government Area of Cross River State, Nigeria.  The survey research design was used in achieving this. To adequately and appropriately execute the project three objectives were formulated.  From these objectives, research questions were generated and hypotheses formulated accordingly to guide data gathering and analysis. The instrument for data gathering was a four point close ended questionnaire from which 150 farmers and 50 extension agents were selected to respond to items in the questionnaire using the census approach.  Data collected from their responses were subjected to two forms of descriptive analysis.  The first was percentage descriptive analysis which was used to x-ray the biodata.  Second, mean and standard deviation were used to treat the research questions.  The third method used is the independent t-test on the three man hypothesis of the study.  The result of the analysis warranted the rejection of the three null hypotheses tested at 0.05 level of significance with 198 degrees of freedom using 1.96 as the critical t-value. It was found out that ecological practices of farmers contribute to climate change, climate change has impacted negatively on bee honey production, and farmers should be educated through agricultural extension education in order to become conscious of their practices on natural resources and mitigate climate change effects in bee honey production.

Purpose: Nutritional status and dietary pattern of 120 randomly selected type-2 diabetic patients of both sexes (age range 18 and 65 years) attending medical outpatient clinics within Abuja metropolis were assessed.

Methods: A cross-sectional survey involving pre-tested and semi-structured questionnaires was used. Socio-demographic characteristics, anthropometric measurements, nutritional status and dietary pattern of the subjects were computed using standard methods.

Results: The result of socio-demographic characteristics indicates that 52% are males and 48% are females. Subjects with primary education constitute 4.2%, about half of them having either secondary (48.3%) or tertiary (47.5%) education. Most (80.8%) of them are married, 32.5% fell within a monthly income range of N50,000 - N100,000 (US $139.07 - $278.14). Anthropometric indices showed that the height of 75% of the respondents was 159.9 ± 7.0 cm, 100% of the respondents’ weight, hip circumference, waist-hip ratio and waist-height ratio are 72.69 ± 16.88 cm, 104.6 ± 12.4 cm, 0.94 ± 0.1 and 0.61 ± 0.1 respectively. The nutritional status of the subjects revealed that only 25% fell within the normal BMI range, with 1.7% being underweight, 20.8% overweight and half of them (52.5%) obese and out of which 27% are morbid. Their dietary patterns showed that the food mostly consumed include cereals, processed cereals, legumes, vegetables, fruits and meat. More than a quarter of the respondents totally avoid sugar in their diet, while 33.33% rarely eat sugar. Eggs (48.33%) have a moderate frequency of consumption.

Conclusion: This study concludes that the dietary practices of the respondents contribute to their poor nutritional status.
