2. Método para el estudio de la producción informativa: medios digitales de Portugal
Abstract The present investigation proposes a method of analysis of information production of digital media. The method employed consists of the analysis of information production, which can be collected from syndication channels in the press media, radio and digital television. The syndication channels of digital media in Portugal has been taken as an examp

3. LA CAPACIDAD DE CORRECCIÓN DE ERRORES Y EL FEEDBACKCORRECTIVO ESCRITO: ESTUDIO DE CASOS DE APRENDICES DE PORTUGUÉS HISPANOHABLANTES
ABSTRACTThe efectiveness of corrective feedback (CF) in written production has been controversial in the last decades (BITCHENER y FERRIS, 2012; TRUSCOTT, 2007; VAN BEUNINGEN, 2010). The investigation focused on experimental studies, with quantitative research, about long-term acquisition and with a restricted range of errors, but recently researchers make a

4. CHEMOSTAT, UM SOFTWARE GRATUITO PARA ANÁLISE EXPLORATÓRIA DE DADOS MULTIVARIADOS
The objective of this work was to develop a free access exploratory data analysis software application for academic use that is easy to install and can be handled without user-level programming due to extensive use of chemometrics and its association with applications that require purchased licenses or routines. The developed software, called Chemostat, empl

5. Reconhecimento de texto e rastreamento de objetos 2D/3D / Text recognition and 2D/3D object tracking
In this thesis we address three computer vision problems: (1) the detection and recognition of flat text objects in images of real scenes; (2) the tracking of such text objects in a digital video; and (3) the tracking an arbitrary three-dimensional rigid object with known markings in a digital video. For each problem we developed innovative algorithms, which

6. Detecção rápida de legendas em vídeos utilizando o ritmo visual / Fast video caption detection based on visual rhythm
Detecção de textos em imagens é um problema que vem sendo estudado a várias décadas. Existem muitos trabalhos que estendem os métodos existentes para uso em análise de vídeos, entretanto, poucos deles criam ou adaptam abordagens que consideram características inerentes dos vídeos, como as informações temporais. Um problema particular dos vídeos,

7. DESAMBIGUAÇÃO DE SENTIDO DE PALAVRAS DIRIGIDA POR TÉCNICAS DE AGRUPAMENTO SOB O ENFOQUE DA MINERAÇÃO DE TEXTOS / WORD SENSE DESAMBIGUATION IN TEXT MINING
This dissertation investigated the application of text mining process from techniques of computing intelligence and machine learning in the problem of word sense ambiguity. The work in the methods of decision support area aimed to develop techniques capable of doing a word meaning disambiguation automatically and also to construct a prototype based on the ap

8. Sistema de detecção e isolamento de falhas em sistemas dinâmicos baseado em identificação paramétrica
The present research aims at contributing to the area of detection and diagnosis of failure through the proposal of a new system architecture of detection and isolation of failures (FDI, Fault Detection and Isolation). The proposed architecture presents innovations related to the way the physical values monitored are linked to the FDI system and, as a conseq

9. Desenvolvimento de um biossensor potenciométrico, à base de soja, para a determinação de uréia / Biossensor potencyometric; Enzymatic membrane; Soy grains
In this work, the objective in study was the development of a biossensor potencyometric for urea detection, starting from the extracted urease of soy grains. Initially, was made a chemometrics study, through a planning factorial 24, objectified to find great conditions for the extraction of the urease without its properties were affected. Starting from this

11. TIARI: Uma Interface para Entrada de Texto em Sistemas de Realidade Aumentada
Augmented Reality interfaces overlap virtual information in a real world scene, augmenting the userâs reality by interacting with virtual and real objects. To make this interaction possible, lots of interfaces were developed trying to make this interaction simple, efficient and intuitive. Some Augmented Reality applications need text input and interfaces li

12. Levenshtein distance for information extraction in databases and for natural language processing.
While performing information extraction or natural language processing tasks, one usually encounters problems when working with data or texts containing noise, typing mistakes or other different kinds of errors. In this thesis we investigate the use of modified Levenshtein edit distances to deal with these problems in two specific tasks. The first one is the
