Os espaços públicos na reconversão da zona da Expo’98

O projecto urbano do Parque das Nações tem sido apontado como um caso de sucesso pelo que para compreendê-lo consideramos necessário analisar não somente o projecto inicial e o resultado final, mas conhecer também, o processo de desenvolvimento do próprio projecto. Ao longo do processo muitos foram os intervenientes e as influências que são aqui identificadas e esplanadas nos seus aspectos mais relevantes. Para reflectir sobre uma fórmula de sucesso a análise centra-se na relevância dos espaços públicos, e a maneira como estruturam a implementação do projecto de urbanização do recinto da Expo '98. Há informação especifica que não sendo de carácter exacto ou científico teve influência no projecto. Começamos por contextualizar apresentando alguns antecedentes ao início do projecto, explicando como se processaram acordos institucionais, tendo como objectivo a integração social com os bairros vizinhos e analisamos a função dos espaços públicos na eliminação de barreiras físicas. Por fim debatemos a influência que o ambiente industrial tem na herança cultural ribeirinha e a actual componente da sustentabilidade e cultura ecológica expressa na presença da água junto á cidade. Por fim apresentamos algumas conclusões relativas ás características dos espaços públicos de maior sucesso no Parque das Nações que ao transformarem a morfologia dos terreno portuário monofuncional viabilizam a sua humanização e o convite à usufruição na frente ribeirinha.

Queue-based agent architecture for multimodal interfaces

This paper presents a queue-based agent architecture for multimodal interfaces. Using a novel approach to intelligently organise both agents and input data, this system has the potential to outperform current state-of-the-art multimodal systems, while at the same time allowing greater levels of interaction and flexibility. This assertion is supported by simulation test results showing that significant improvements can be obtained over normal sequential agent scheduling architectures. For real usage, this translates into faster, more comprehensive systems, without the limited application domain that restricts current implementations.

On-demand hd video using Jini based grid

This research establishes the feasibility of using a network centric technology, Jini, to provide a grid framework on which to perform parallel video encoding. A solution was implemented using Jini and obtained real-time on demand encoding of a 480 HD video stream. Further, a projection is made concerning the encoding of 1080 HD video in real-time, as the current grid was not powerful enough to achieve this above 15fps. The research found that Jini is able to provide a number of tools and services highly applicable in a grid environment. It is also suitable in terms of performance and responds well to a varying number of grid nodes. The main performance limiter was found to be the network bandwidth allocation, which when loaded with a large number of grid nodes was unable to handle the traffic.

Impact of captions on deaf and hearing perception of multimedia video clips

We investigate the impact of captions on deaf and hearing perception of multimedia video clips. We measure perception using a parameter called Quality of Perception (QoP), which encompasses not only a user's satisfaction with multimedia clips, but also his/her ability to perceive, synthesise and analyse the informational content of such presentations. By studying perceptual diversity, it is our aim to identify trends that will help future implementation of adaptive multimedia technologies. Results show that although hearing level has a significant affect on information assimilation, the effect of captions is not significant on the objective level of information assimilated. Deaf participants predict that captions significantly improve their level of information assimilation, although no significant objective improvement was measured. The level of enjoyment is unaffected by a participant’s level of hearing or use of captions.

Recent global trends in the Chinese construction industry and its market

The rapidly increasing construction demand in China, particularly spurred by the coming 2008 Beijing Olympic Games and the 2010 Shanghai Expo, provides challenging opportunities for overseas construction enterprises. Therefore understanding the structure and dynamics of construction industry in China is crucial, particularly the potential changes of the market after the China's entry into the World Trade Organization. This paper analyses the development of construction economics and institutional regulations in the construction market, and provides a comprehensive image on the Chinese construction sector in the global environment.
