Wavelength assignment using a hybrid evolutionary computation to reduce cross-phase modulation

In this paper, we propose a hybrid methodology based on Graph-Coloring and Genetic Algorithm (GA) to solve the Wavelength Assignment (WA) problem in optical networks, impaired by physical layer effects. Our proposal was developed for a static scenario where the physical topology and traffic matrix are known a priori. First, we used fixed shortest-path routing to attend demand requests over the physical topology and the graph-coloring algorithm to minimize the number of necessary wavelengths. Then, we applied the genetic algorithm to solve WA. The GA finds the wavelength activation order on the wavelengths grid with the aim of reducing the Cross-Phase Modulation (XPM) effect; the variance due to the XPM was used as a function of fitness to evaluate the feasibility of the selected WA solution. Its performance is compared with the First-Fit algorithm in two different scenarios, and has shown a reduction in blocking probability up to 37.14% when considered both XPM and residual dispersion effects and up to 71.42% when only considered XPM effect. Moreover, it was possible to reduce by 57.14% the number of wavelengths.

A exigibilidade judicial dos direitos sociais

A falta, de concretização de alguns direitos fundamentais, como os sociais de saúde e educação, que demandam certos custos para o Estado, ainda representa um desafio ao constitucionalismo brasileiro. Em decorrência, os tribunais vêm se deparando com demandas relacionadas a materialização dos referidos direitos, tais como pedidos de fornecimento de medicamentos não fornecidos pela rede pública de saúde ou a garantia de matrícula de estudante no sistema público de educação. Tratam-se assim de pedidos de ordens judiciais para que a administração pública cumpra seu dever constitucional, através de prestações positivas. Tal fenômeno, incluído por boa parte da doutrina dentro do que se convencionou chamar de "judicialização da política" não está isento à criticas. Em seu desfavor, argumenta-se que (1) o Judiciário está agredindo o princípio da separação de poderes, haja vista que a função administrativa, com sua discricionariedade, deve ser preservada com o Executivo não devendo na mesma se imiscuírem os magistrados, sendo-lhes defeso interferir em políticas publicas; (II) não há legitimidade democrática dos juízes, pois os mesmos não foram eleitos pelo povo; (III) o Judiciário não está preparado e tecnicamente capacitado para tal tipo de demanda; (IV) por envolver prestações positivas e assim necessidade de recursos públicos para a sua concretização, uma, determinação judicial nesse sentido contrariaria o princípio da legalidade e anterioridade orçamentária e encontraria sérios óbices em sua concretização pela reserva do possível. O presente estudo se propõe não só a analisar os referidos argumentos, como também examinar as fronteiras do sistema jurídico e do político, para concluir pela legitimidade ou não de tal conduta judicial, bem como a análise da natureza, do alegado caráter programático e da difícil delimitação dos direitos sociais e sua proteção judicial, ou seja, se procura, em síntese, examinar o papel do judiciário brasileiro no problema da efetivação dos direitos sociais, como garantidor do mínimo existencial.

Desempenho de escolares rurais em narrativas escritas e possíveis relações com variáveis de perfil

The goal of this research was to characterize written stories, produced by students, without complaint of language development (oral and written), from pictographic support. In a specific way, it has been searched, in those stories, elements that could grant coherence, applying that performance with the participants’ profile variables. It was characterized as a descriptive-exploratory study, held at a rural municipal school in the State of Parana. Twenty-one (21) students of both genders and ages between seven and nine years old have participated in this study. Data collection consisted of two narratives requests: one oral, after being released, to the child, four pictures placed in sequence to form a story, and one written. This writing production had been taken for the analysis. The results have indicated that most children (71.42%) managed to produce coherent stories, seventeen (80%) in story 1 and thirteen (61%) in story 2. As to the relation of that coherence with the students’ profile in story 1, there has been no statistically significant association, for none of the analyzed variables (gender, age and education), whereas there has been a statistically significant association with gender in story 2 (p-value 0.027). It is considered that the use of the pictographic support in developing stories have been confirmed as a facilitating strategy for its construction, for it has enabled the production of coherent narratives.

Aquisição da linguagem: as crianças e sua atitude responsiva a perguntas abertas

Introduction: Since their first month of life, babies already show alternation in their communication, in which adults have an important role, assuming interaction turns with the child through questions known as eliciting questions. Verifying this alternation incited us to analyze children’s responsive attitudes toward the questions of the adult interlocutor. Objetives: (1) describe and characterize the kinds of responsive attitudes children have to open questions; (2) verify if there are any differences between the developed and non-developed kinds in the answers. Material and method: data were extracted from 28 interviews (recorded both in audio and in video) with four male children (5-6 years-old) who attended a public Kindergarten. Results: regarding the first objective, 88.7% of the attitudes were answers to the questions, 4.7% were non-responses and 6.6% were confirmation requests. Regarding the second objective, 48.2% of the answers were developed and 51.3%, non-developed. Conclusion: Although the high percentage of answers indicates that the children showed themselves sensitive to the demands of the adult interlocutor, the small percentage difference between developed and non-developed answers also indicates that children mostly depend on their assistance to develop their utterance since they oscillate between restricting themselves to the demand of the interlocutor and expanding it.

Proposta para planejamento da arborização viária do bairro do Alvinópolis, município de Atibaia - SP

The urban arborization planning must consider technical criteria, to avoid future conflicts between trees and the urban space, and sociocultural criteria, to satisfy the local population necessities. Considering this principle, the present work proposes an arborization plan for a pilot area enclosing three of the principal streets from Alvinopolis District, county of Atibaia – SP. In order to tackle this objective, requests of tree removal were analyzed to get a panorama of how the subject takes place in the county. After that, promising sites for tree planting were selected in the enclosing area, and urban arborization of the three (3) main streets were retake, proposing necessary substitutions. Finally, 238 residents all over Alvinopolis County have been interviewed, with the objective of appraising their subject sense and focus on environmental education. Then three maps were made: the first one representing characteristics that influence in arborization, the second representing the present arborization and the nine (9) necessary substitutions, and the third representing the plan for the arborization of the pilot area. From the interviewed people, 79% shown themselves favorable to urban arborization, otherwise it does not discard the necessity to inform population about adequate species, county laws and adequate handling of trees.

The boardings social-cognitivists of the motivation point two orientations: the intrinsic, that it is seen as natural trend of the individual, in which it executes an activity for considering it attractive, and the extrinsical, with the purpose to take care of to requests or pressures of other people, or to demonstrate to aptitudes and abilities. This research investigates the extrinsical motivation and its consequences in the pertaining to school performance of a pupil considered for the professors as having learning difficulties. The results of the research indicate the influence of the pertaining to school and familiar environment in the motivation and, this in the pertaining to school performance of the pupil, pointing the relevance of studies on the thematic one.

Osteotomia sagital da crista alveolar para instalação de implantes Bicon

This case report presents details of a new surgical technique for mandibular ridge sagittal osteotomy and expansion associated to immediate dental implants in atrophic ridges. The bone atrophies represents a challenge for the surgeons that intends to modify this situation. In the past, the only viable option was the onlay bone graft. However, the bone graft requests a second surgical site that certainly increases the postoperative morbidity, without mentioning the longer treatment time required. The sagittal osteotomy of the alveolar crest represents a faster option, because it eliminates the time requested for bone graft integration, providing rehabilitation of edentulous areas with thin alveolar crests that otherwise would need additi onal surgical procedures for a satisfactory result. The authors report a clinical case in which this technique was used with the installation of a Bicon dental implant in the same surgical time, showing all the steps for this single-tooth rehabilitation.

Complicações Associadas aos Enxertos Ósseos Aposicionais com Osso Autógeno

Introdution: Tooth extraction results in alveolar ridge resorption due to the progressive reabsorption, which frequently is a limitating factor of dental implants treatment, in function of the insufficient bone height for execution, could be indicated the use of grafts for increase of the alveolar edge. However, the success of the bone graft requests the meticulous attendance of the clinical stages. Proposition: The objective of this research was to evaluate the postoperative complications associated to the autogenous bone grafts. Materials and Methods: Through a random retrospective analysis, 90 file records of patients submitted to the surgical procedure of autogenous bone graft in the period of January from 2000 to the March of 2008. A clinical record was elaborated with base in the necessary data for this evaluation. Results: About the file data analysis, 59 female with average of 49,42 years and 31 male with average of 47,90 years. The previous diseases most related were arterial hypertension, stomachache and diabetis. The smokers was noticed in 13,3% of patients. The donor site most used was a mandibular ramus. The postoperative complications in receiving area represented 17,8% of file datas analysed and in the donor site only one patient showed parestesis. Conclusion: Among the total analyzed files it was observed that the postoperative complications associated with the autogenous bone grafts represented 18,9% of the patients submitted to the procedure, more frequently affecting the receiving area, obtaining partial exposure of the bone graft and absence of inserted gingiva on vestibular cortical bone.
