Interferências do crioulo no português escrito em alunos cabo-verdianos do 1º ciclo do ensino secundário

Com o presente trabalho, subordinado ao tema “Interferências do Crioulo no Português Escrito em Alunos Cabo-verdianos do 1º Ciclo do Ensino Secundário: Implicações no Insucesso Escolar, pretende-se tentar compreender quais são as dificuldades que esses alunos apresentam na produção escrita na língua de escolarização, através da identificação e análise das tipologias de interferências do Crioulo no Português escrito. Para melhor enquadrar o estudo, fez-se uma revisão da literatura, de obras e artigos referentes à temática e à teoria proposta para a análise da problemática em questão. Para a realização desta investigação, o contexto de intervenção foi o Liceu “Amílcar Cabral”, situado na cidade de Assomada, no concelho de Santa Catarina. Para o efeito do estudo fez-se a recolha, e a análise de dados de um “corpus”de textos escritos, produzidos por 20 alunos do 1º Ciclo do Ensino Secundário (10 de 7º Ano e 10 de 8º Ano), a partir de um estímulo extrínseco que lhes foi distribuído. Finalmente, feita a análise, os resultados demonstram que a maioria dos alunos apresenta erros de interferência do Crioulo no Português escrito. Ressalta -se ainda que, a grande dificuldade desses alunos reside na estrutura morfossintáctica, centralizando-se na morfologia do verbo, nas concordâncias entre o determinante e o nome quanto ao número e ao género, no uso do determinante, artigo definido e na conjugação pronominal reflexa. A partir daí, são apresentadas, nas recomendações, propostas de algumas actividades sistematizadas de ensino de estruturas do Português partindo da tipologia de erros cometidos e utilizando um processo contrastivo (Ccv/Port).

A 802.11p prototype implementation

This paper presents an IEEE 802.11p full-stack prototype implementation to data exchange among vehicles and between vehicles and the roadway infrastructures. The prototype architecture is based on FPGAs for Intermediate Frequency (IF) and base band purposes, using 802.11a based transceivers for RF interfaces. Power amplifiers were also addressed, by using commercial and in-house solutions. This implementation aims to provide technical solutions for Intelligent Transportation Systems (ITS) field, namely for tolling and traffic management related services, in order to promote safety, mobility and driving comfort through the dynamic and real-time cooperation among vehicles and/or between vehicles and infrastructures. The performance of the proposed scheme is tested under realistic urban and suburban driving conditions. Preliminary results are promising, since they comply with most of the 802.11p standard requirements.

Error control on spectral data of four-wave mixing based on a-SiC technology

In this paper we exploit the nonlinear property of the SiC multilayer devices to design an optical processor for error detection that enables reliable delivery of spectral data of four-wave mixing over unreliable communication channels. The SiC optical processor is realized by using double pin/pin a-SiC:H photodetector with front and back biased optical gating elements. Visible pulsed signals are transmitted together at different bit sequences. The combined optical signal is analyzed. Data show that the background acts as selector that picks one or more states by splitting portions of the input multi optical signals across the front and back photodiodes. Boolean operations such as EXOR and three bit addition are demonstrated optically, showing that when one or all of the inputs are present, the system will behave as an XOR gate representing the SUM. When two or three inputs are on, the system acts as AND gate indicating the present of the CARRY bit. Additional parity logic operations are performed using four incoming pulsed communication channels that are transmitted and checked for errors together. As a simple example of this approach, we describe an all-optical processor for error detection and then provide an experimental demonstration of this idea. (C) 2014 WILEY-VCH Verlag GmbH & Co.

Simulation of wave action on a moored container carrier inside Sines’ Harbour

The integrated numerical tool SWAMS (Simulation of Wave Action on Moored Ships) is used to simulate the behavior of a moored container carrier inside Sines’ Harbour. Wave, wind, currents, floating ship and moorings interaction is discussed. Several case scenarios are compared differing in the layout of the harbour and wind and wave conditions. The several harbour layouts correspond to proposed alternatives for the future expansion of Sines’ terminal XXI that include the extension of the East breakwater and of the quay. Additionally, the influence of wind on the behavior of the ship moored and the introduction of pre tensioning the mooring lines was analyzed. Hydrodynamic forces acting on the ship are determined using a modified version of the WAMIT model. This modified model utilizes the Haskind relations and the non-linear wave field inside the harbour obtained with finite element numerical model, BOUSS-WMH (Boussinesq Wave Model for Harbors) to get the wave forces on the ship. The time series of the moored ship motions and forces on moorings are obtained using BAS solver. © 2015 Taylor & Francis Group, London.
