1. Validación del Índice de Calidad Formal como modelo para la evaluación de websites: el caso de la e-Administración local portuguesa
Abstract The results derived from a content analysis applied to websites from 308 municipalities in Portugal are discussed. Despite the name of the method (which could possibly lead to confusion), the study has exclusively focused on the formal parameters of online communication; that is, audiovisual appearance, information architecture, usability, accessibi

2. Herramienta auditora sobre el acceso y preservación de la información audiovisual televisiva
Abstract This paper aims at describing the audit tool that can determine the correct management, preservation and access to audiovisual information within television networks. The audit is presented in the format of an auditing tool that analyzes a number of parameters, such as accessibility, state of preservation, human resources and training, economic fund

3. O estado sizígio de televisão: por uma metodologia de pesquisa do som no audiovisual
The present dissertation has as the aim of studying the design of the television sonorities and the creation of ambiences for programs. To reach this aim it was necessary to compare the theoretical and methodological postulates, through an empirical research, where I experiment my own methodological procedure, which was constructed based on the theoretical f

4. Visualização e simulação de sinais cardiológicos utilizando técnicas de realidade aumentada
Nowadays, the presence of computers is noted, even subtle, in almost every area of human knowledge and activity. The advantages emerged by computers are many, but there are still drawbacks that need efficient solutions. The tech devices and audiovisual ways of communication between the user and computers are still a great challenge, because to use successful

5. Real-time Interactive Systems for Integrated Audiovisual Processing / Sistemas interativos de tempo real para processamento audiovisual integrado
A popularizaÃÃo das artes mediadas por computador e, em especial, do visual-jÃquei (VJ), estimula o desenvolvimento de novos sistemas multimÃdia de tempo real. Esta demanda vem sendo atendida por programas especÃficos para o controle de exibiÃÃo de vÃdeos e efeitos como Resolume, ArKaos e diversas variantes; e com linguagens de programaÃÃo visual c

6. Plastic neural changes and reading improvement caused by audiovisual training in reading-impaired children
This study aimed at determining whether audiovisual training without linguistic material has a remediating effect on reading skills and central auditory processing in dyslexic children. It was found that this training resulted in plastic changes in the auditory cortex, indexed by enhanced electrophysiological mismatch negativity and faster reaction times to

7. Fear recognition in the voice is modulated by unconsciously recognized facial expressions but not by unconsciously recognized affective pictures
Multisensory integration is a powerful mechanism for increasing adaptive responses, as illustrated by binding of fear expressed in a face with fear present in a voice. To understand the role of awareness in intersensory integration of affective information we studied multisensory integration under conditions of conscious and nonconscious processing of the vi

8. Visual speech speeds up the neural processing of auditory speech
Synchronous presentation of stimuli to the auditory and visual systems can modify the formation of a percept in either modality. For example, perception of auditory speech is improved when the speaker's facial articulatory movements are visible. Neural convergence onto multisensory sites exhibiting supra-additivity has been proposed as the principal mechanis

9. MEG demonstrates a supra-additive response to facial and vocal emotion in the right superior temporal sulcus
An influential neural model of face perception suggests that the posterior superior temporal sulcus (STS) is sensitive to those aspects of faces that produce transient visual changes, including facial expression. Other researchers note that recognition of expression involves multiple sensory modalities and suggest that the STS also may respond to crossmodal

10. A continuous-speech interface to a decision support system: II. An evaluation using a Wizard-of-Oz experimental paradigm.
OBJECTIVE: Evaluate the performance of a continuous-speech interface to a decision support system. DESIGN: The authors performed a prospective evaluation of a speech interface that matches unconstrained utterances of physicians with controlled-vocabulary terms from Quick Medical Reference (QMR). The performance of the speech interface was assessed in two sta
