Hipersegmentação de palavras: análise de aspectos prosódicos e discursivos

This paper deals with hypersegmentation of words that are characterized by the unconventional employment of a graphical boundary (using a white space or hyphen) within the limits of the word, as in "em bora" (“although”, using a white space), and "chama-da" (“called”, using the hyphen). In a study conducted on these data, we identified motivations arising not only from their literate nature but also from the morphosyntactic and prosodic information. We showed that there are linguistic features recurrent in these registers of word boundaries, based on the analysis of texts produced by the students who attended the last four years of elementary school in a public school in São Paulo. In this paper, we advance on this study by selecting data whose characteristics do not match those which were recurrent. We will argue that the unconventional presence of boundary within the written word limits may be interpreted as representing prosodic configurations (of intonation and rhythm nature) which contribute to the construction of the relation of meanings in the text.

Rapidly varying boundaries in equations with nonlinear boundary conditions. The case of a Lipschitz deformation

We analyze the behavior of solutions of nonlinear elliptic equations with nonlinear boundary conditions of type partial derivative u/partial derivative n + g( x, u) = 0 when the boundary of the domain varies very rapidly. We show that the limit boundary condition is given by partial derivative u/partial derivative n+gamma(x) g(x, u) = 0, where gamma(x) is a factor related to the oscillations of the boundary at point x. For the case where we have a Lipschitz deformation of the boundary,. is a bounded function and we show the convergence of the solutions in H-1 and C-alpha norms and the convergence of the eigenvalues and eigenfunctions of the linearization around the solutions. If, moreover, a solution of the limit problem is hyperbolic, then we show that the perturbed equation has one and only one solution nearby.

WORD-FINDING DIFFICULTIES, VERBAL PARAPHASIAS, AND VERBAL DYSPRAXIA IN 10 INDIVIDUALS WITH FRAGILE-X-SYNDROME

Speech/language disorders are common in the fragile X syndrome. [Howard-Peebles, 1979: Am J Hom Genet 31:214-222; Renier et al., 1983: J Ment Defic Res 27:51-59; Sparks, 1984: Birth Defects and Speech-Language Disorders, pp, 39-43; Hanson et al., 1986: Am J Med Genet 23:195-206]. Verbal paraphasias have been considered a rare feature and word-finding difficulties have seldom been reported. Here we report on ten Brazilian patients who were evaluated for speech/language disturbances and found that word-finding difficulties were present in 50% of the cases, which is a slightly higher frequency than that of clear dyspraxia. We suggest, therefore, that word-finding difficulties and verbal dyspraxia can be a common feature within the spectrum of this syndrome. Additional speech findings are discussed.

Optimization of neural classifiers based on bayesian decision boundaries and idle neurons pruning

In this article we describe a feature extraction algorithm for pattern classification based on Bayesian Decision Boundaries and Pruning techniques. The proposed method is capable of optimizing MLP neural classifiers by retaining those neurons in the hidden layer that realy contribute to correct classification. Also in this article we proposed a method which defines a plausible number of neurons in the hidden layer based on the stem-and-leaf graphics of training samples. Experimental investigation reveals the efficiency of the proposed method. © 2002 IEEE.

As fronteiras: retomando a palavra e libertando significados. Quem sou eu? As mulheres e as identidades redescobertas

From one dimension of culture, the word boundary breaks away from the idea of territorial boundary defined a priori as something fixed to the delineation of boundaries. Released this commitment, it can be thought of in other dimensions: as of transition moments of identity experienced by individuals, for women, compared to established norms. Questioning the determinant and connected speech processes of change, they left the banks in which they lived and sought recognition of self, identity and new choices have taken up other possibilities for being, social inclusion, coupled with the guarantee of their rights. Recognizing the existence of this movement, I propose a look at border on the inclusion of women as widows in order to observe the multiple identities of their female protagonists. This reflection aims to take account of social fraying beyond the limits and directions in taxes and if the widow, to expand the boundaries of its meaning and consider the possibility of hybrid subjects, differentiated, and therefore mobile and moving all the time an ongoing performance of operations, as well as contemporary studies have shown about gender relations that take into account the distinctions of race, class, ethnicity, and especially for generations.

Electrical Properties at Grain Boundaries Influenced by Cr3+ Diffusion in SnO2.ZnO.Nb2O5-Films Varistor Prepared by Electrophoresis Deposition

SnO2-based varistors are strong candidates to replace the ZnO-based varistors due to ordering fewer additives to improve its electrical behavior as well as by showing similar nonlinear characteristics of ZnO varistors. In this work, SnO2-nanoparticles based-varistors with addition of 1.0 %mol of ZnO and 0.05 %mol of Nb2O5 were synthesized by chemical route. SnO2.ZnO.Nb2O5-films with 5 μm of thickness were obtained by electrophoretic deposition (EPD) of the nanoparticles on Si/Pt substrate from alcoholic suspension of SnO2-based powder. The sintering step was carried out in a microwave oven at 1000 °C for 40 minutes. Then, Cr3+ ions were deposited on the films surface by EPD after the sintering step. Each sample was submitted to different thermal treatments to improve the varistor behavior by diffusion of ions in the samples. The films showed a nonlinear coefficient (α) greater than 9, breakdown voltage (VR) around 60 V, low leakage current (IF ≈ 10-6 A), height potential barrier above 0.5 eV and grain boundary resistivity upward of 107 Ω.cm.
