It Is the Time for Portuguese Texts!
Publication . Craveiro, Olga; Macedo, Joaquim; Madeira, Henrique
In this work, we introduce a software testbed for temporal processing of Portuguese texts, composed by several building blocks: identification, classification and resolution of temporal expressions and temporal text segmentation. Starting from a simple document, we can reach a set of temporally annotated segments, which enables the establishment of relationships between words and time. This temporally enriched information is then placed into an Information Retrieval system. This work represents a step forward for Portuguese language processing, with notorious lack of tools. Its main novelty is temporal segmentation of texts. Even with target application in temporal aware Information Retrieval, the described software tools can be used in other application scenarios.
A European Portuguese Children Speech Database for Computer Aided Speech Therapy
Publication . Lopes, Carla, Alexandra Calado Lopes; Veiga, Arlindo; Perdigão, Fernando
This paper introduces a European Portuguese speech database containing spoken material recorded from children. The need for such database arose from the need of train phone models for the development of a computer aided speech therapy system. Articulatory disorders affect a significant number of children in pre-school age. We propose a system intended to assist and reinforce the conventional speech therapy programs. Through the systematic use of games, it learns the phones where the child has more difficulty to pronounce. The child is then taken to train the production of those phones by playing games. Another interest of a children speech database is that accurate children's phone recognition is only possible using training data that reflects the population of users. It is a difficult task due to the high pitch of children's speech
Polymers, Biomanufacturing and Regenerative Medicine
Publication . Mitchell, Geoffrey R.; Domingos, M.; Bártolo, Paulo J.
Polymers have a major contribution to make in the field of regenerative medicine in order to develop and deploy biological substitutes that restore, maintain, or improve tissue function. There are realistic opportunities to create tissues using an engineered extracellular matrix or scaffold and biologically active molecules. A number of different approaches to preparing scaffolds have been explored and the requirements for materials and personalization identified. We review the methodologies and materials available and report on recent work at the CDRSP to integrate and provide control of the processes to provide a realistic biomanufacturing process.
A survey on HDR visualization on mobile devices
Publication . Magalhães, Luis; Bessa, Maximino; Urbano, Carlos; Melo, Miguel; Peres, Emanuel; Chalmers, Alan; Pasi Saarikko
There is a vast body of literature concerning the capture, storing, transmission and display of High Dynamic Range (HDR) imaging. Nevertheless, there are few works that try to address the problem of getting HDR on mobile devices. Their hardware limitations, such as processing power, storage space, graphics capabilities and screen characteristics, transform that problem in a big challenge. However, since more and more HDR content is being produced and given that in a few years it can become a standard, it is necessary to provide the means to visualize HDR images and video on mobile devices. The main goal of this paper is to present a survey on HDR visualization approaches and techniques developed specifically for mobile devices. To understand what are the main challenges that need to be addressed in order to visualize HDR on mobile devices, an overview of their main characteristics is given. The very low dynamic range of most of mobile devices' displays implies that a tone mapping operator (TMO) must be applied in order to visualize the HDR content. The current status of the research on TMO will be presented and analyzed, a special attention will be given to the ones that were developed taking in account the limited characteristics of the mobile devices' displays. Another important issue is visualization quality assessment, meaning visualize HDR content without losing the main characteristics of the original HDR content. Thus, evaluation studies of HDR content visualization on mobile devices will be presented and their results analyzed.
Sustainability Communication in Rural Tourism: Website Content Analysis, in Viseu Dão Lafões Region (Portugal)
Publication . Pato, Maria Lúcia; Duque, Ana Sofia
In the last few years, the relationship between tourism and sustainability has been con-solidated. In the context of rural tourism, this connection is even stronger given the environmental specificities and the natural framework of this type of tourism. To achieve sustainability behaviors, it is crucial that rural tourism lodgings communicate their essence, as well the products and experiences available for tourists. This because it is a common practice for visitors to look for more information on the internet about where they will be staying, before booking their tourist experience. The main objective of this study is the analysis of the information provided by rural tourism lodgings, through their websites, regarding sustainability issues. The territory selected for the development of this study is the Portuguese Viseu Dão Lafões Region, located in the center of Portugal. Based on other studies, the methodology includes a content analysis, conducted on 39 rural tourism lodging websites. The results show that some improvements are needed, to clarify and emphasize the message about sustainable practices, in these rural lodgings. Some practical recommendations are provided, that can be adapted to these rural tourism lodgings, or others.
