However, many research questions remain open in tasks involving video sequences. Several applications demand the understanding of complex events in videos, such as traffic monitoring, person re-identification, security and surveillance. In this work, we address the problem of human action recognition in videos through a multi-stream network that incorporates both spatial and temporal information. The main contribution of our work is a stream based on a new variant of the visual rhythm, called Learnable Visual Rhythm (LVR). We employ a deep network to extract features from the video frames in order to generate the rhythm. The features are collected at multiple depths of the network to enable the analysis of different abstraction levels. This strategy significantly outperforms the handcrafted version on the UCF101 and HMDB51 datasets. Experiments conducted on these datasets show that our final multi-stream network achieved competitive results compared to state-of-the-art approaches.

Many works in the literature combine different aspects to recognize the actions, which has shown to be superior than individual results. Just as important as the definition of representative and complementary aspects is the choice of good combination methods that exploit the strengths of each aspect. In this work, we propose a novel fusion strategy based on two fuzzy integral methods. This strategy is capable of generalizing other common operators, besides it allows more combinations to be evaluated by having a distinct impact in sets linearly dependent. Our experiments show that the fuzzy fusion outperforms the most commonly-used weighted average on the challenging UCF101 and HMDB51 datasets.

Through the combination of qualitative and quantitative approaches, it was possible to map the users’ initial perceptions, points of improvements, and expectations for the information assessment. Ultimately, it was possible to observe that although both single and co-op modes were introduced to participants, the latter created a greater level of engagement and motivation, increasing the participants’ interest.

These two issues are discussed in this article supported by an analysis of some Greek and Latin textbooks published over the last twenty years. In the middle of the article I introduce the translation issue as an activity that has many merits in the language learning process and I propose that it can be used not only for testing but mainly for ancient language teaching as a valid activity for language practice and improvement. A case study, supported by Aesop’s fable “The cicada and the ant”, is developed as a way to illustrate the most common basic principles outlined in this article.

Therefore, it is necessary to offer products and services that can be fully controlled by users, transforming complex processes into simple and objective interactions. For this, initially a preparation of the case study to define the object to be evaluated, which concluded that an analysis of the use of the search tools of the Android system could meet the requirements of the proposed work. This work has as a premise to create a combination of usability assessment techniques which allowed adding eye tracking data from the users’ experience to the experiments with traditional research methods. At the end of the study, it was possible to evaluate the contribution of each technique applied.

For a more accurate data collection for research purposes, correct food distribution control is required. As an alternative to maintain an amount of homogeneous food in fish feed, this work presents a control system of low cost controlled feeding via microcontroller board, taking into account the amount of food and feeding time of the animals. The prototype developed is divided into three parts, an electromechanical part, the electronic part that is the Arduino platform and a small software that intervenes the previous parts.

As a result, copper-doped photocatalyst generated higher hydrogen amount compared to the others. The high photocatalyst performance was due to the greater lamp spectrum absorption, marked by the low bandgap value, and high photoactivity justified by the low rate of electronic recombination. The hydrogen generation in the quartz reactor was seven times higher than the annular one, and when at maximum light power, it is comparable to the most sophisticated reaction systems found in literature. The larger light exposure area per unit volume of the quartz reactor compared to the annular one is the reason why it obtained better results due to the lower emitted photon blockade, with a 1.81% apparent quantum yield.

Berberine and emodin possess several pharmacological properties and have been shown to be particularly effective against the entry and replication of several viruses. We show that emodin and berberine trigger a virucidal effect on ZIKV. When the virus was exposed to 160 µM of berberine, a reduction of 77.6% in the infectivity was observed; when emodin was used (40 µM), this reduction was approximately 83.3%. Dynamic light scattering data showed that both compounds significantly reduce the hydrodynamic radius of virus particle in solution. We report here that berberine and emodin, two natural compounds, have strong virucidal effect in Zika virus.

In a direct way we present a relationship between two slow-roll inflationary potentials, and we apply this framework to show how to construct an eternal inflation from chaotic inflation, or even, a natural inflation from hilltop inflation, easily.

This paper explores how variability in the connection points between structures affects the coupled dynamics. One at a time, two different one-dimensional waveguides are attached to a thin plate through a different set of point connections. Measurements considering randomly spaced connections were made and the experimental results are presented and compared to previously developed models. When multiples attachments are considered, the structure accommodates standing-like waves between the attachments, amplifying its response. It was possible to see the variability due the random spacing and, in a frequency-averaged sense, good agreement between the experimental data and the models were obtained. A comparison of the spatial response of the experiment and the infinite system is also presented.

Dentro deste contexto, neste trabalho, objetivou-se avaliar à composição físico-química, mineral e o comportamento higroscópico de quatro diferentes marcas de preparado sólido para refresco sabor manga. As isotermas de adsorção foram construídas através do ajuste de dados experimentais aos modelos matemáticos de BET, GAB, Oswim e Henderson. Os resultados físico-químicos da avaliação mostram que os preparados sólidos para refrescos são fontes consideráveis de ácido ascórbico e açúcar redutor e no que se refere à composição mineral são fontes importantes de cálcio, sódio e potássio. Foi também observado que os preparados sólidos das quatro marcas estudadas são produtos muito higroscópicos.

Os CIS são estruturas de cooperação regional e intergovernamental formados entre municípios para atuar de forma conjunta na área da saúde pública. As práticas de gestão econômica e financeira são vistas como importantes para apoiar o processo decisório visando ao planejamento, execução, controle e avaliação de desempenho das organizações em geral. Trata-se de um estudo qualiquantitativo, de natureza aplicada e descritiva, no qual as percepções dos gestores dos CIS quanto à utilização destas práticas de gestão foram coletadas por meio de instrumento de pesquisa formatado com escalas do tipo Likert e tratados de forma objetiva, com uso de técnicas de estatística descritiva e exploratória. Assim, os CIS foram classificados e agrupados conforme o grau de utilização das práticas de gestão. Os principais achados indicam que o CIS é uma instância de execução e realização e não, propriamente, de formular estratégias para reduzir custos e ampliar e qualificar a oferta do serviço público de atendimento à saúde. Por esta razão, faz uso reduzido das práticas de gestão econômica e financeira. Além disso, a preocupação precípua da gestão dos CIS é voltada para o cumprimento estrito das obrigações legais e normativas para si e para os municípios associados.

The platform is intended to address specific issues with tablet usage in a classroom setting, and address problems with technology adoption in education, particularly in Brazil. We evaluated the DTP in two separate studies, a Usability experiment in a laboratory setting, and an in-situ experiment in Brazilian classrooms, with the aim of identifying specific problems with the current solution, and identifying usage patterns that better engage students in the classroom. We found that our DTP leads, overall, to a very satisfactory experience. However, any such platform aimed at classroom usage should take special care to address note-taking, and tasks related to collaboration, sharing, and general social aspects of the classroom experience.

On the other hand, the translation critic is interested in identifying, after comparing the original text and the translated text, how much the first was altered, smoothed, explained, interpreted, etc. by the translator and, if possible, which motives lead to these interferences in the source text. The present work, using as illustration one of the most controversial extracts of the translation of the Bible's New Testament (the first verse of the first chapter of St. John's Gospel), tries to identify a field for the application of Sperber and Wilson's Relevance theory, viewing it as a tool that can be used to aid both the translator and the translation critic.

Como o tradutor reproduzirá na nova língua a força particular e peculiar mais os significados tanto interiores como exteriores criados unicamente e exclusivamente pelo escritor original para (e em) uma língua e cultura diferentes? Traduzir um poema não é compor outro poema. Se o tradutor assim o faz, não teremos uma tradução de uma obra que já existe, mas uma nova obra e um novo autor. Será isso o que o leitor de uma tradução estará esperando? Estes são os pontos discutidos neste artigo, utilizando como exemplo um poema grego da série Anacreontea e uma tradução para o português. Finalmente, o que a lexicografia tem a ver com tudo isso? Palavras-chave: poesia grega, tradução de poesia,
