This paper introduces a family of shape-preserving binary approximating subdivision schemes by applying a shape-preserving variant on the Lane-Riesenfeld algorithm. Using the symbols of subdivision schemes, we determine convergence and smoothness, Hölder continuity, and support size of the limit curves. Furthermore, these schemes produce monotonic and convex curves under the certain conditions imposed on the initial data.
La Arqueología de la Arquitectura a revisión
Authors: Azkarate Agustín
Published: December 2020

La idea de lo que es y caracteriza la Arqueología de la Arquitectura puede variar sensiblemente de unos países a otros en función de sus respectivas tradiciones historiográficas. Está por hacer un estudio de conjunto de los diversos enfoques y metodologías sobre las construcciones y los entornos construidos, una realidad material que contiene múltiples dimensiones y que puede ser observada desde las más variadas escalas, temporales, espaciales y conceptuales. Con esta breve aportación se quiere ofrecer una primera síntesis de este complicado rompecabezas, pensando sobre todo en quienes quieren introducirse en la materia. Se reivindica una Arqueología de la Arquitectura abierta, plural, responsable y comprometida.
Une stratégie au service de la réussite : Robert de Thurnham, un officier anglais en Aquitaine (1189-1211)
Authors: Tranchant Marie
Published: December 2020

La carrière de Robert de Thurnham donne l’exemple d’une ascension spectaculaire permise par le service royal au tournant du xiiie siècle. Lorsqu’à son retour de croisade en 1194 Robert de Thurnham est fait sénéchal d’Anjou par Richard Cœur de Lion, c’est le premier Anglais nommé à ce poste depuis la création de l’office sous Henri II. L’analyse détaillée de sa carrière entre 1194 et 1211 permet de considérer sa nomination, d’abord en Anjou puis en Poitou en 1201, comme une expérimentation de la Couronne, qui espère ainsi mieux contrôler son sénéchal. L’expérience est inédite et elle n’est pas reproduite. Ce parcours continental de Robert de Thurnham peut être lu comme un choix stratégique permettant d’accéder à davantage d’opportunités que sur les îles Britanniques, et ainsi de favoriser son ascension. En faisant bénéficier de ces contacts son frère aîné Étienne de Thurnham, qui sert pour sa part le roi en Angleterre, il développe avec lui une stratégie commune afin d’augmenter le prestige et le patrimoine de leur famille.
The spiritual quest of the Buddha in the Dungkar cave temple – Indian sources and Western Tibetan image-making. Part 1: the narrative cycle from Tuṣita heaven up to the Enlightenment
Authors: Kalantari Christiane , Allinger Eva
Published: December 2020

The case study identifies and analyses the detailed depiction of the story of the life of the Buddha up to the Enlightenment in the early Western Trans-Himalayan Buddhist temple of Dungkar. It examines the relation between image and text, asseses the art-historical context, and explores the narrative modes. Comparative investigations based on multi-sited and multi-disciplinary research in historical Western Tibet (Tsamda/Ngari, Spiti, and Ladakh) show that the designers of the visual programmes at each of these sites developed different solutions of cycles based on textual sources and also visual models have been used in various ways.
Joseph de Guignes et l’Histoire générale des Huns, des Turcs, des Mogols et des autres Tartares occidentaux (1756-1758) ou comment écrire une histoire universelle des Tartares au xviiie siècle

Published: December 2020

Aujourd’hui presque oubliée, l’Histoire générale des Huns de Joseph de Guignes (1756-1758) représente une synthèse de l’ensemble des savoirs sur l’histoire de l’Asie centrale qui circule dans la France du milieu du xviiie siècle. L’objet de cet article est de mettre en lumière le contexte de production de ce texte, les sources utilisées ainsi que la thèse défendue par son auteur. À travers cet exemple, il s’agira d’étudier les modalités de la construction d’un savoir orientaliste.
The fragrance of belonging in Russian Beringia
Authors: Panáková Jaroslava
Published: December 2020

The aim of this study is to explore how the smells associated with particular emotions encode the feeling of belonging in Russian Beringia. The differing olfactory patterns are conceptualised within the broad socio-political processes of Soviet and post-Soviet modernisation. The odours, the mental representations of the odorous stimuli, are considered socially constructed. Following David Howes (2002) and Constance Classen et al. (1994), it is assumed that the cultural politics of olfaction intensify under the changing social regimes. The study further draws on David Chaney’s concept of lifestyle (1996) that proves to be helpful in enhancing the investigation of the interrelation between social differentiation and aesthetic patterns in the context of the Soviet mission civilisatrice. In the analysis of the impact of the Soviet (and post-Soviet) policies on the native olfactory practices, the study shifts the focus from deodorisation (a concept that refers to elimination of those odours that colonizing western discourse finds socially unacceptable) towards sanitation (process in which cleanliness as a synecdoche for civility may lead to, but not necessarily does, a repudiation of certain odours). It demonstrates that the realms where the senses, aesthetic, and social hierarchies overlap have a wide spectrum of cultural forms, often unintended from the point of view of the Soviet or post-Soviet policy makers.
“Fertilissimi sunt auri Dardae, setae vero et argenti”. Notes on some ancient open-air gold mining sites in Ladakh
Authors: Vernier Martin
Published: December 2020

This paper is intending to give a descriptive account of four sites from Central Ladakh that nearby inhabitants consider to be ancient open-air gold mines and, in so doing, tries to link some physical remains with what the legend of the ants, inherited from Antiquity, may be interpreted as meaning. The point here is not to add another page to the tale, but rather to point to some possible archaeological evidence supporting the fact that Ladakh might well be considered as a possible location of origin for these gold-related tales.

Occurrence and Seasonal Variations of Lead Concentrations in River Water and Edible Vegetables Grown along Morogoro River Bank
Authors: Joseph G. , Temba B.
Published: December 2020

Urban vegetable farming is popular in Tanzania and other countries partly due to readily available market and reliable transport to reach consumers. River banks are usually used to grow such vegetables due to closer proximity to water and whenever necessary use such water for irrigation. However in urban settings river water pollution by toxic heavy metals and subsequent accumulation of the metals in nearby grown vegetables has been reported as among major sources of exposure to humans and animals. Heavy metals, including lead (Pb) have many health effects to human and animals ranging from acute to chronic illnesses. This study was conducted to assess the occurrence of lead in Morogoro river and in edible vegetables (Amaranthus retroflexus) grown along the river bank. Water and vegetable samples collected during dry and rainy seasons were prepared and analysed for occurrence and levels of lead using Atomic Absorption Spectrometry (AAS). It was found that concentration of Lead in the water and vegetable samples were up to 0.95 mg/L, and 0.026 mg/Kg respectively. It was also found that 77% of the water samples and 28% of the vegetable samples had lead levels above the WHO recommendations. The frequency and levels of lead occurrence varied with topographical, diurnal and seasonal characteristics of sample collection. The results of this study raise concerns on the use of water for human and animal consumption from rivers which run across urban areas and call for further studies to investigate for any health consequences to consumers
One Health Approach (OHA) in Selected Urban Settings in Tanzania: Knowledge, Attitudes, Awareness, and Practices
Authors: Muhanga M.I. , Malungo J.R.S. , Kimario K.A.
Published: December 2020

Attainment of optimal health calls for collaboration between animals, humans, and environmental health professionals together with understanding the consequences of animals, humans, and environment interactions on health. In cognizant of this, the government in Tanzania introduced One Health Strategic Plan (2015–2020), little is empirically known on how this plan has facilitated the enhancement of knowledge, awareness, attitudes, and practices (KAPs) under One Health Approach (OHA). This article analyses KAPs under OHA from a cross-sectional study conducted in Morogoro, Tanzania. Data were collected by a questionnaire from 1440 respondents obtained through a multistage sampling procedure, 80 Focus Group discussions (FGDs) participants and 16 key informant interviewees. IBM-SPSS v.20 analysed quantitative data while qualitative data were organised into themes on specific objectives. Results revealed that only 32.3% (95% CI:30.3 to 35.3) had adequate OH knowledge. Only 5% (95% CI:4.0 to 6.1) were aware of OHA concept and practices; 3.8% (CI 95%, 2.8 to 4.8) managed to identify collaborative efforts and strategies, and 2.5% (CI 95%, 1.7 to 3.4) correctly explained/ described OHA. Whereas, 38.5% (95% CI:32.6 to 37.5) had a positive (favourable) attitude towards OHA. Despite the efforts outlined in the OH Strategic Plan to promote OHA, there is little awareness and knowledge on OHA. This indicates that the One Health Strategic Plan (2015–2020) and other initiatives have not significantly facilitated the enhancement of KAPs. This study recommends strengthening efforts towards OHA information dissemination to enhance awareness and knowledge on the concept and practices.
Predicting Loan Approval of Bank Direct Marketing Data Using Ensemble Machine Learning Algorithms
Authors: Meshref Hossam
Published: December 2020

The Bank Marketing data set at Kaggle is mostly used in predicting if bank clients will subscribe a long-term deposit. We believe that this data set could provide more useful information such as predicting whether a bank client could be approved for a loan. This is a critical choice that has to be made by decision makers at the bank. Building a prediction model for such high-stakes decision does not only require high model prediction accuracy, but also needs a reasonable prediction interpretation. In this research, different ensemble machine learning techniques have been deployed such as Bagging and Boosting. Our research results showed that the loan approval prediction model has an accuracy of 83.97%, which is approximately 25% better than most state-of-the-art other loan prediction models found in the literature. As well, the model interpretation efforts done in this research was able to explain a few critical cases that the bank decision makers may encounter; therefore, the high accuracy of the designed models was accompanied with a trust in prediction. We believe that the achieved model accuracy accompanied with the provided interpretation information are vitally needed for decision makers to understand how to maintain balance between security and reliability of their financial lending system, while providing fair credit opportunities to their clients.
A profecia bíblica na defesa da justiça e da vida: Se calarem a voz dos profetas as pedras falarão (Lc 19,40)
Authors: Zanini Rogério , Belegante Dorvalino
Published: December 2020

Resumo: A presente reflexão, a partir de uma abordagem teológica, tem por objetivo compreender o movimento profético bíblico na defesa da justiça e da vida dos pobres. O mundo atual com sua crescente desigualdade social exige mais profetas, que corajosamente denunciam este modelo de sociedade excludente e anunciam outro estilo de vida. A pandemia desvelou um sistema capitalista sem coração, que prioriza o capital, a economia e não a vida. A crise provocada pela pandemia desmascarou um vírus ainda pior: o da indiferença egoísta. Desvelamento que sobrou até para os profetas bíblicos, uma vez que o presidente do Brasil recebeu a designação de profeta. Um motivo a mais para perguntar-se: o que significa ser profeta? Portanto, contexto social, político e religioso profícuo para não deixar cair a profecia, conforme pedido do profeta Dom Helder Camara. Questão de fundo que justifica e valida a preocupação de buscar na mística profética, elementos que impulsionam à missão dos cristãos de caminhar com Deus praticando a justiça, a misericórdia e o amor na história (Mq 6,8).
Философские корни элитологии
Authors: Karabushenko Paul L.
Published: December 2020

Все науки вышли из философской колыбели, продолжая нести в себе ее следы, испытывать на себе ее влияние, использовать ее терминологию и методологические технологии. Элитология одной из последних отделилась от философии, хотя одной из первых и появилась в недрах ее исторического знания. Элитология имеет не только продолжительную историю, но и весьма глубинные философские основания, дающие ей определенные преимущества. Большую часть своей научной истории элитология существовала именно в качестве некой философской парадигмы, имевшей различные формы теоретического проявления. Именно это многообразие и придавало ей устойчивость и выживание даже в самых неблагоприятных условиях. Именно во многом благодаря этому, элитология и сформировалась и позиционирует себя в качестве комплексной научной дисциплины, всесторонне изучающей феномен элиты и элитности. При этом сама философия продолжает и далее разрабатывать тему избранности и превосходства лучшего, невзирая ни на какие научные нововведения.
Многообразие элитологического опыта указывает на то, что элита представляет собой отдельно взятый социокультурный феномен, требующий специального объективного комплексного исследования. Именно философия обеспечивает эту комплексность и надежную методологическую основу. И судя по всему, элитология не торопится порывать свои генетические связи с философской традицией и продолжает весьма активно использовать ее данные в своих собственных исследованиях. В настоящей работе предпринимается осмысление философских основ элитологии, без чего дальнейшее развитие ее в качестве самостоятельной научной дисциплины будет весьма затруднительным.

The groundnut seed composed of approximately equal weight of
fatty and non-fatty oil. The groundnut cake (kulikuli- Hausa
name in Nigeria) contains concentrated protein, minerals, and
vitamins in addition research finding revealed that no part of the
nut is a waste. The kernel without the nuts can be used as hay
to feed animals like, horse or ash manure. Planting machine or
planter that is normally required to produce more food is beyond
the buying capacity of smallholder’s farmers, which result in low
productivity especially in the production of grains. An improved
manual two-row groundnut planter was developed and
evaluated for its performance using locally sourced materials
which can be adapted for gardens and smallholder farmers. The
machine has the following parts which are furrow opener,
handle, frame, hopper, discharge tube, metering unit, and roller
housing. The machine was evaluated for field capacity and
metering efficiency (3 hole metering devices) at different forward
speeds. It was observed that the machine field capacity efficiency
of was 82%. Using standard error bars the highest metering
efficiency of 92% was observed at 0.7 m s -1 machine speed.
The ANOVA (analysis of variance) shows that speed
as significant effect on metering efficiency with a p-value of 5.44E-18. The
planter could plant an average of five seeds per point. It is
simple, cheap and the ergonomics of the machine was considered
which makes it easy to operate.
Semantic Conflict and Response Conflict in the Stroop Task
Authors:   St. Petersburg State University, Starodubtsev Alexey , Allakhverdov Mikhail
Published: December 2020

The most common ways researchers explain the Stroop effect are either through semantic or through response conflict. According to the literature, there are several methods capable of disentangling these conflicts: to use words outside of the response set, to use associatively related colors and words, or to use a “2:1” paradigm (requiring the same response for two types of stimuli). However, we believe that these methods cannot entirely differentiate semantic and response conflicts. We propose the following alternative method: when naming the color of a printed word (e.g., red, yellow, etc.) in the Stroop test, participants were asked to use different color names for some colors. For example, the red-colored stimuli had to be named by the word “yellow”. This approach allowed us to create semantically congruent stimuli, but with the conflict at the response level (the word red appears in red, but the participants have to say “yellow” because of the rule). Some stimuli remain congruent at the response level, but with the conflict at the semantic level (the word yellow appears in red, and the participants have to say “yellow” because of the rule). The results showed that semantically congruent stimuli do not produce the Stroop effect even if the meaning of the word corresponds to an incorrect response. In turn, congruence at the response level reduces the interference effect, but interference remains significant. Thus, the response conflict affects the magnitude of the Stroop effect only when there is a semantic conflict. Our data do not correspond to models that assume direct activation of responses corresponding to word meaning

Published: December 2020

The fundamental research conducted by looking at the phenomenon of group fights and how ethnocentrism and conflict influence each other indigenous ethnic groups in West Papua. This study used descriptive qualitative method, through field studies (in-depth interviews) and literature study. The results showed that with a low level of understanding of the history of the conflict supported ever experienced by the perpetrators of communication, there is a trend of negative information transformation process to be effective. So as to absorb the negative information, aspects of ethnocentrism group members appear. The emergence of these aspects lead to the awareness and solidarity groups to join forces in-group. Other findings also showed that the factors causing conflict among indigenous ethnic groups in West Papua can be summarized in two points, namely; The first tendency puts another group at a level lower social interaction, and the second is the attempt appointment of existence itself by an ethnic group seeking recognition coupled behavior (respect) from inside and outside the group by scapegoating other groups. In the indigenous ethnic group communication, attitude and behavior aspects play a role in the formation of a negative message, based on the main factors. The tendency of formation of the group because of its frequency along the occurring hereditary. Related conflict and ethnocentrism, can be drawn that the results of the analysis found the substance also major causal relationship. Where, a communal conflict can result from the manifestation of ethnocentrism aspects into forms of behavior conflict. In contrast with the presence of conflict can also strengthen or weaken ethnocentrism.
Ulayat Right of Customary Law Community

Published: December 2020

Ulayat right is a right that is given a magical aspect as a threatening force and can sanction as a basis of legitimacy of control over a territory or a plot of land called ulayat land.Â Ulayat Land is a plot of land that belongs to a group of people in a region.Â Although the customary law community has full customary authority to control, cultivate and utilize its ulayat land, but its formal juridical authority is not as strong as that of the State.Â The position of indigenous and tribal peoples is ultimately acknowledged conditional through various state regulations issued by the Government as in the Basic Agrarian Law Number 5 of 1960 Article 3. The conditional recognition that indigenous and tribal peoples can be recognized throughout 1) in reality Still exist, 2) in harmony with the times, 3) in accordance with national interests, 4) confirmed by local regulations.Â Such conditional recognition directly or has strengthened the State's domination of the rights possessed by society, it means that indigenous and tribal peoples will always be defeated when faced with state to defend their rights.Â The consequences of such an imbalance will clearly affect the role of indigenous and tribal peoples in the management and utilization of their ulayat land.

Published: December 2020

In order for health institutions to continue their activities, the goods and services they need must be supplied at the right time, in the right amount, at the right quality, at an affordable price and from the right source. This is possible with an effective supply chain management and selection of the right supplier. Supplier selection studies in the health sector are almost nonexistent, therefore, it was wanted to contribute to the literature by studying in this sector. In this study, it was aimed to work with the right suppliers to ensure that a dental health center provides critical medical supplies. First of all, the products of vital importance were determined by ABC (Always, Better Control)-VED (Vital, Essential, Desirable) matrix analysis and a supplier list was created. The best suppliers were selected with the Zero-One Goal Programming method based on AHP priorities, one of the multi-criteria decision making methods, by determining the criteria suitable for the sector.It is thought that this model will contribute significantly to the literature and will save time in supplier selection studies in the health sector.

A interdisciplinaridade é um conceito epistemológico ainda em formação, que relaciona áreas do conhecimento distintas que ajudam no desenvolvimento de soluções de problemas de alta complexidade. Neste artigo tenta-se demonstrar que a adoção dessa mentalidade interdisciplinar nas universidades faz com que os núcleos de pesquisa e desenvolvimento obtenham melhores resultados no que tange ao desenvolvimento tecnológico e ao retorno financeiro. Tendo como foco o curso de engenharia elétrica, foi feito um levantamento da produção acadêmica interdisciplinar e de registros de patentes entre universidades brasileiras e americanas, a fim de analisar quantitativamente e qualitativamente os impactos da adoção do ensino interdisciplinar por essas universidades. Assim, pôde-se constatar que a interdisciplinaridade somada a outros fatores, como o apoio financeiro à pesquisa e o incentivo por parte das universidades em criar ambientes colaborativos, aumenta o número e a relevância da produção acadêmica, refletindo na criação de produtos, soluções e tecnologias.

Published: December 2020

Com o aumento da interação física entre humanos e robôs, seja no ambiente fabril ou equipamen-tos de engenharia assistiva, pesquisas científicas passaram a desenvolver novos atuadores, além dos moto-res elétricos. A finalidade é tornar o contato entre o ser humano e a máquina mais seguro. Nesse cenário, um forte candidato a atuador é o músculo de Mckibben. O músculo de Mckibben é um tipo de músculo artificial pneumático que possui dinâmica rápida, similar aos motores elétricos, elevada razão potência/peso e baixo custo de aquisição de peças. Além disso, o atuador tem complacência natural similar ao tecido muscular esquelético, o que pode suavizar colisões catastróficas ou emular o comportamento da muscula-tura humana. Assim, esse artigo propõe o desenvolvimento e a caracterização de um músculo de Mckibben, para aplicações no campo da robótica de manipulação. Como metodologia, foram utilizadas soluções ana-líticas baseadas em teorias de deformação para materiais poliméricos e soluções numéricas baseadas em regressões e interpolações lineares, permitindo a caracterização estática e dinâmica do atuador. Como re-sultado, o estudo obteve um atuador de baixo custo, em torno de R$5,00, e elevados coeficientes de corre-lação, R entre 0,8424 e 0,9969, para o modelamento fenomenológico.

Authors: N. Medina Rai , D. Melo Igor , O. N. Teixeira Mariana
Published: December 2020

Este trabalho apresenta uma nova abordagem para a análise de estabilidade de tensão considerando distorções harmônicas em sistemas elétricos de potência. O método proposto se baseia na modelagem de um problema de otimização com restrições não lineares, em que a função objetivo é determinada pela maximização do fator de carregamento do sistema, considerando restrições de desigualdade com limites mínimos e máximos de magnitude de tensão, distorção harmônica individual e total, potência ativa e reativa. Os testes são conduzidos utilizando o sistema IEEE 14 barras modificado a partir da inclusão de fontes harmônicas, a fim de verificar o máximo carregamento através do método proposto. Além disso, serão incluídas neste artigo análises de contingências simples de linhas e transformadores mostrando o impacto das restrições consideradas na formulação proposta e contingências no valor calculado do fator de máximo carregamento.

Authors: D. Davila Espinoza Raschid , J. Triveno Vargas Francisco
Published: December 2020

A estabilidade dos sistemas de energia é de vital importância; nesse sentido, novas estruturas de controle vem sendo estudadas e implementadas para melhorar o desempenho das unidades que compõem um sistema interligado. Este trabalho propõe a estrutura de controle robusta LQR-2DOF como um regulador de velocidade para turbinas hidráulicas (ou controlador de frequência em geradores). Para implementar essa técnica, são feitas modificações na sua estrutura para que possa ser empregada como regulador, isto porque a estrutura original foi proposta para problemas de rastreio. O controlador é projetado e simulações são executadas para verificar uma possível melhoria na sua resposta e sua viabilidade de uso nos sistemas de energia quando comparado ao controle PID.

Published: December 2020

As equações das máquinas de relutância chaveada nos eixos de referência dq0 são complexas. Esse fato faz com que o controle de torque de máquinas de relutância chaveada usando Controle Vetorial seja um processo árduo. Ao longo das décadas, modelos matemáticos usando fluxo concatenado e indutância como variáveis de estado e o método de Controle Direto de Torque foram desenvolvidos para contornar os problemas de complexidade mencionados. Neste artigo, propõe-se uma estratégia simples de controle de torque de máquinas de relutância chaveada usando Controle Vetorial. O método aqui apresentado utiliza a transformação dqx, que é uma generalização da transformação Park, e a derivada da indutância como variável principal. Os resultados de simulação mostraram que a oscilação do torque diminuiu 11 vezes e o fator de oscilação do torque diminuiu 13 vezes em comparação com o controle chaveado tradicional. Além disso, usando a estratégia proposta neste trabalho, o enfraquecimento e enriquecimento de campo se tornam simples e diretos, aumentando a flexibilidade de operação desse tipo de máquina. A formulação matemática, bem como os resultados teóricos e de simulação para uma máquina de relutância chaveada 6/4 são discutidos. Também são apresentados resultados de simulação para enfraquecimento e enriquecimento de campo.
SHADOW MODELLING ALGORITHM FOR PHOTOVOLTAIC SYSTEMS ANALYSIS AND SIMULATION
Authors: A. de Sá Bárbara , Dezuo Tiago , Ohf Douglas
Published: December 2020

In this paper, an algorithm capable of modelling shadows from nearby obstructions onto photovoltaic arrays is proposed. The algorithm developed is based on the calculation of the solar position in the sky for any given instant in order to obtain the shadow projection for any object point. The convexity properties of objects and their shadows are used to allow a precise three-dimensional solution with reduced computational power without the need to consider a vast grid of points. The idea is extended to provide the shading patterns for a desired range of time and to calculate the eciency rate of the irradiation power incident on the array in comparison to the non-shadowed case. The algorithm has interesting applications, such as optimizing array positioning and orientation, evaluating the impact of new obstructions on pre-existing array installations, allowing precise and practical data for control strategies and MPPT techniques for partially shaded systems, calculating more realistically constrained payback scenarios and nding the optimal PV array interconnection. The results obtained are illustrated by a numerical example, in which the eects of a nearby building in the irradiation received by a photovoltaic array throughout the year is analyzed.

Esta pesquisa investiga a capacidade das redes Perceptron de Múltiplas Camadas (MLP) e Função de Base Radial (RBF) na tarefa de Detecção de Novidade (DN) no reconhecimento de expressões faciais usando recursos de vídeo. O conjunto de dados de vídeo utilizado é produzido por atores profissionais em estúdio com estados afetivos básicos do rosto humano. Os algoritmos Viola-Jones, Kanade-Lucas-Tomasi (KLT) e Análise de Componentes Principais (PCA) são usados na fase de pré-processamento para extrair atributos da face. Os resultados avaliam o desempenho das redes MLP e RBF na tarefa DN, usando novas expressões faciais compatíveis com as utilizadas na fase de treinamento e também examinam a capacidade das redes em DN usando as faces de atores nunca antes vistos pelas redes. Neste processo, as redes MLP e RBF têm uma precisão de 98% para tarefa de classificação, 68% e 98% para DN com dados semelhantes aos dados da fase de treinamento e 100% para DN com dados totalmente novos. Assim, este trabalho reúne métodos e técnicas aplicadas na DN utilizando Redes Neurais Artificiais (RNA), visando a produção de sistemas interativos de cognição no campo da computação afetiva, baseados em técnicas de Inteligência Artificial (IA) e Visão Computacional.
Abordagens de Solução do Problema de Fluxo de Carga baseadas em Aproximações de Padé com Denominador Comum
Authors: De Jesus Rodrigues Silva Lara Raquel , Damasceno Freitas Francisco
Published: December 2020

Este artigo apresenta abordagens para o cálculo da solução do Problema de Fluxo de Carga (PFC) via método de adaptação holomórfica (Holomorphic Embedding Method - HEM). Duas abordagens para o cálculo de aproximações de Padé com fração racional tendo denominador comum são propostas. A partir destas aproximações, são calculados equivalentes modais obtidos na forma de polos e resíduos. Com base em um índice de dominância modal, são avaliadas as contribuições de cada termo da expansão modal visando determinar um modelo reduzido modal. A partir da redução modal, determina-se um limiar para o número máximo de termos das séries. As aproximações são calculadas a partir das partes real e imaginária das séries de MacLaurin de tensão que resultam da expansão das séries de potência. A avaliação das técnicas propostas foi efetuada com base em simulações em um circuito elétrico resistivo e em dois sistemas de potência com 14 e 118 barras. Os resultados indicam a potencialidade das abordagens como uma ferramenta para fornecer uma base para a análise modal aplicada ao problema de adaptação holomórfica.
Evaluation of the CO2 Emissions and Energy Efficiency of the Train Intercidades Campinas-São Paulo with Fuel Cells and Batteries
Authors: H. Batista1 André , V. Ribeiro Edgar , Naturesa Jim , B. C. Salles Mauricio
Published: December 2020

This work presents a case study of the Train Intercidades project between Campinas and São Paulo, comparing, in the sense of increasing efficiency and reducing CO2 emissions, the supply of diesel generators, batteries and fuel cells. For this, a model of the track and the train to be analyzed was developed using HOMER Pro software, and energy simulations were carried out considering the combinations of energy sources mentioned above. It was verified that the use of batteries as an auxiliary source of energy made it possible to decrease the installed power and increase the overall efficiency in simulations with diesel generators. In relation to the replacement of diesel generators by fuel cells in different scenarios, an increase in global efficiency of about 10%, the complete elimination of carbon dioxide emissions at the point of use, and an increase in operating costs of more than 300% due to the consumption of hydrogen gas were achieved. However, this financial gap is expected to narrow with the development of fuel cell technology in the coming years, making this option more economically viable in the future.
