1. Applicability of computer vision in seed identification: deep learning, random forest, and support vector machine classification algorithms
ABSTRACT The use of computer image analysis can assist the extraction of morphological information from seeds, potentially serving as a resource for solving taxonomic problems that require extensive training by specialists whose primary method of examination is visual identification. We propose to test the ability of deep learning, SVM and random forest algo

2. Leaf venation pattern to recognize austral South American medicinal species of "cow's hoof" (Bauhinia L., Fabaceae)
ABSTRACT The leaves extracts of some species of Bauhinia L. s.l. are consumed to treat diabetes, inflammation, pains and several disorders in traditional medicine in austral South America. Despite its wide use and commercialization, sale is not controlled, and botanical quality of samples is not always adequate because of plant misidentification and adultera

3. Chromophoreasy, an Excel-Based Program for Detection and Integration of Peaks from Chromatographic and Electromigration Techniques
This paper describes the development, evaluation, features and applications of Chromophoreasy, an alternative Excel-based program for recognition and integration of chromatographic and electrophoretic peaks. The proposed recognition is made according to parameters adjustable by the analyst, such as time range, noise smoothing window size and slope/curvature

4. The incidental binding of color and shape is insensitive to the perceptual load
Abstract The binding of information in visual short-term memory may occur incidentally when irrelevant information for the task at hand is stored together with relevant information. We investigated the process of the incidental conjunction of color and shape (Exp1) and its potential association with the selection of relevant information to the memory task (E

5. TLR2 and TLR4 mediated host immune responses in major infectious diseases: a review
Abstract During the course of evolution, multicellular organisms have been orchestrated with an efficient and versatile immune system to counteract diverse group of pathogenic organisms. Pathogen recognition is considered as the most critical step behind eliciting adequate immune response during an infection. Hitherto Toll-like receptors (TLRs), especially t

6. Health professionals experiences in assisting children and adolescents who have cancer: a phenomenological study / Vivências de profissionais de saúde na assistência a crianças e adolescentes com câncer: um estudo fenomenológico
Cancer corresponds to a group of diseases that have in commom the power to proliferate abnormal cells of a primitive embrio origin in any part of the organism. Despite the scientific advances which allow a raise in the chances of cure, cancer triggers psychological repercussions in patients and their families. In this scenario of illness it is tantamount tha

7. A contribuição da União Europeia à governança da mudança climática global: explicando as condições para a actorness da UE
As a regional organization, the European Union's role in global climate governance faces constraints that do not apply to other members of the United Nations Framework Convention on Climate Change (UNFCCC) and Kyoto Protocol. Addressing that uniqueness, this article provides a theoretical and empirical analysis of how the elements of actorness (recognition,

9. Uma avaliação sobre características espaço-temporais baseadas em invariantes de cor para reconhecimento de ações
Local spatiotemporal feature has been proved to be a powerful tool to represent latent patterns of moving objects in video scenes. In particular, recognition of human actions has been the principal focus for various growing applications, including video indexing, content-based video retrieval, video summarization, filtering of unwanted content, rating of mov

12. Reconhecimento de padrões em imagens por descritores de forma / Pattern recognition in images via shape descriptors
A idéia de capacitar uma máquina a reconhecer o ambiente em que atua tem motivado pesquisadores a investir esforços no estudo do mais complexo dos sentidos humanos, a visão. A visão é, antes de tudo, uma tarefa de representação e processamento de informações, sendo portanto adequada ao tratamento computacional. Visto que ainda não se possuem méto
