Wordnet.Br: An Exercise of Human Language Technology Research

This paper reports the ongoing project (since 2002) of developing a wordnet for Brazilian Portuguese (Wordnet.Br) from scratch. In particular, it describes the process of constructing the Wordnet.Br core database, which has 44,000 words organized in 18,500 synsets Accordingly, it briefly sketches the project overall methodology, its lexical resourses, the synset compilation process, and the Wordnet.Br editor, a GUI (graphical user interface) which aids the linguist in the compilation and maintenance of the Wordnet.Br. It concludes with the planned further work.

CALCULATION of MAGNETODONOR STATES IN InP and POLARON EFFECTS

Far-infrared transitions in polar semiconductors are known to be affected by the presence of shallow donor impurities, external magnetic fields and the electron-LO-phonon interaction. We calculate the magnetodonor states in indium phosphide by a diagonalization procedure, and introduce the electron-phonon interaction by the Frohlich term. The main effects of this perturbation are calculated by a multi-level version of the Wigner-Brillouin theory. We determine the transition energies, from the ground state to excited states, and find good qualitative agreement with recently reported absorption-spectroscopy measurements in the 100-800 cm(-1) range, with applied magnetic fields up to 30 T. Our calculations suggest that experimental peak splittings in the 400-450 cm(-1) range are due to the electron-phonon interaction.

ARISupport - Interaction support for augmented reality systems

The communication between user and software is a basic stage in any Interaction System project. In interactive systems, this communication is established by the means of a graphical interface, whose objective is to supply a visual representation of the main entities and functions present in the Virtual Environment. New ways of interacting in computational systems have been minimizing the gap in the relationship between man and computer, and therefore enhancing its usability. The objective of this paper, therefore, is to present a proposal for a non-conventional user interface library called ARISupport, which supplies ARToolKit applications developers with an opportunity to create simple GUI interfaces, and provides some of the functionality used in Augmented Reality systems. © Springer-Verlag Berlin Heidelberg 2005.

Methods and tools for encoding the WordNet.Br sentences, concept glosses, and conceptual-semantic relations

This paper presents the overall methodology that has been used to encode both the Brazilian Portuguese WordNet (WordNet.Br) standard language-independent conceptual-semantic relations (hyponymy, co-hyponymy, meronymy, cause, and entailment) and the so-called cross-lingual conceptual-semantic relations between different wordnets. Accordingly, after contextualizing the project and outlining the current lexical database structure and statistics, it describes the WordNet.Br editing GUI that was designed to aid the linguist in carrying out the tasks of building synsets, selecting sample sentences from corpora, writing synset concept glosses, and encoding both language-independent conceptual-semantic relations and cross-lingual conceptual-semantic relations between WordNet.Br and Princeton WordNet © Springer-Verlag Berlin Heidelberg 2006.

Interactive DC-DC converters tools for instant design and education

This paper deals with the usage of interactive simulations tools to serve as an oriented design tool for the lectures and laboratory experiments in the power electronics courses. A dynamic and interactive visualization of simulations for idealized converters in steady state are provided by the proposed educational tools, allowing students to acquire qualification in non-isolated DC-DC converters, without previous circuitry knowledge, either without the usage of sophisticated simulation packages. The interaction with proposed simulation tools can be accomplished by student using direct or graphic mode. In direct mode the parameters related with the design of converter can be inserted simply editing default values presented in textboxes, while in the graphic mode students interact indirectly with design information by manipulating visual widgets. In order to corroborate the proposed interactive simulation tools, comparisons of results from buck-boost and boost converters on proposed tools and a well-known simulator package with those on experimental evaluation from laboratory classes were presented. © 2009 IEEE.

Facial pain associated with fibromyalgia can be marked by abnormal neuromuscular control: A cross-sectional study

Background. Temporomandibular disorder (TMD) development in fibromyalgia syndrome (FMS) is not yet fully understood, but altered neuromuscular control in FMS may play a role in triggering TMD. Objective. The purpose of this study was to verify the association between neuromuscular control and chronic facial pain in groups of patients with FMS and TMD. Design. A cross-sectional study was conducted. Methods. This study involved an analysis of facial pain and electromyographic activity of the masticatory muscles in patients with FMS (n=27) and TMD (n=28). All participants were evaluated according to Research Diagnostic Criteria for Temporomandibular Disorders and surface electromyography (SEMG). Myoelectric signal calculations were performed using the root mean square and median frequency of signals. Results. The data revealed premature interruption of masticatory muscle contraction in both patient groups, but a significant correlation also was found between higher median frequency values and increased facial pain. This correlation probably was related to FMS because it was not found in patients with TMD only. Facial pain and increased SEMG activity during mandibular rest also were positively correlated. Limitations. Temporal conclusions cannot be drawn from the study. Also, the study lacked a comparison group of patients with FMS without TMD as well as a control group of individuals who were healthy. Conclusions. Altered neuromuscular control in masticatory muscles may be correlated with perceived facial pain in patients with FMS. © 2013 American Physical Therapy Association.

À procura da música sem sombra: Chabanon e a autonomia da música no século XVIII

Em À procura da música sem sombra, Lia Tomás analisa o trabalho do pensador francês Michel-Paul-Guy de Chabanon (1730-92), cujo livro Da música em si e suas relações com a palavra, as línguas, a poesia e o teatro foi uma espécie de manifesto erudito a favor da música instrumental enquanto gênero autônomo, conceito que teria tido fundamental importância para o romantismo do século XIX e os movimentos que o sucederam. Tomás disseca a obra de Chabanon mantendo o autor no seu contexto. Violinista, amigo de Voltaire, Chabanon era um ativo participante das discussões sobre arte e música do seu tempo. Opôs-se às ideias musicais de Rousseau e outros enciclopedistas, como a origem unitária da música e da palavra, o papel subalterno da música na ópera e a não diferenciação entre linguagem verbal e musical. A autora discorre com precisão sobre os subsídios estéticos e filosóficos fornecidos por Chabanon para a reflexão sobre a música instrumental, e que foram elaborados com o objetivo explícito de delimitar as características desta e demonstrar suas diferenças e autonomia: a música sem sombra a que se refere Lia Tomás. O trabalho traz na íntegra a primeira parte do livro de Chabanon, escrito de maneira deliciosamente coloquial e por isso praticamente ignorado em sua época.

Teoria histórico-cultural e intervenções pedagógicas: possibilidades e realizações do bom ensino

This text has the objective of reflecting and socializing the educa- tional practices and experiences of formation in service carried out in cities of the states of Paraná and São Paulo, as deployment of researches, projects and extension courses. The present elaboration contemplates studies on the organization of teaching and it is gui- ded according to the Historical-Cultural Theory, which sustains the pedagogical interventions to Children Education and Basic Educa- tion. The Historical-Cultural Theory is presented as a theoretical reference for a purpose of acting in a humanization and emancipa- tion perspective. Therefore, so that the didactic procedures be rich in meaning, the communication, the affection and the choice of the resources and procedures must act as essential characteristics in the teaching process.

Distúrbios do Sono em Pacientes com Fibromialgia

Introdução: A fibromialgia é uma doença caracterizada principalmente por dor músculo-esquelética difusa e crônica. Os distúrbios do sono em fibromiálgicos podem ter papel não somente na etiologia da dor crônica, mas também na perpetuação dos sintomas, portanto o estudo das condições do sono nestes pacientes é relevante na medida em que possibilita um entendimento das condições fisiopatológicas e permite uma abordagem ampla para o tratamento da fibromialgia. Objetivo: Apresentar a relação entre os distúrbios do sono e os sintomas da fibromialgia e sua importância na avaliação dos fibromiálgicos. Metodologia: Foi realizado levantamento bibliográfico do período de 1990-2009, nas bases de dados Medline, Pubmed, Lilacs e Scielo, através das palavras chaves: sleep, fibromyalgia, sleep disorders, insomnia, pain. Resultados: A literatura demonstra uma alta prevalência de distúrbios do sono em pacientes portadores de fibromialgia e uma relevante relação entre as anormalidades no padrão do sono e o sintoma da dor crônica.
