Framework para comercialização de soluções de smart cities: o caso PT

Com um número cada vez maior de cidadãos a viver em grandes aglomerados urbanos, as cidades necessitam de se adaptar e tornar mais inteligentes por forma a serem sustentáveis. Desta forma, o conceito de smart city implica a integração de várias dimensões da gestão da cidade, mediante uma abordagem integrada e sustentada, criando um novo mercado per si. Mas, para responder a estas necessidades e conquistar este novo mercado, as empresas têm que se organizar por forma a sustentar as suas decisões estratégicas com ferramentas que permitem a análise e avaliação deste novo paradigma. Baseado nos conceitos de smart cities/cidades inteligentes, este trabalho desenvolve um conjunto de ferramentas que permitem a análise e avaliação de novos mercados pela empresa PTInovação, criando um modelo para a implementação de um mapa de calor/heat map que apresenta as cidades com maior potencial de mercado a nível mundial. Com base neste modelo, é então efetuada uma instanciação do modelo que permite analisar 7 casos diferentes de cidades localizadas na América, África, Ásia e Europa. A partir da análise realizada, é efetuado um caso de estudo para a cidade de Cartagena das Índias, na Colômbia. Este caso de estudo efetua a análise do portfólio de oferta da PTInovação, estuda as necessidades específicas dos utilizadores locais e analisa os potenciais competidores no mercado local, permitindo a realização de uma análise SWOT/TOWS que induz a criação de um plano de ação que permite mapear o processo de entrada da empresa neste mercado.

Context-aware framework for collaborative applications

Future pervasive environments will take into consideration not only individual user’s interest, but also social relationships. In this way, pervasive communities can lead the user to participate beyond traditional pervasive spaces, enabling the cooperation among groups and taking into account not only individual interests, but also the collective and social context. Social applications in CSCW (Computer Supported Cooperative Work) field represent new challenges and possibilities in terms of use of social context information for adaptability in pervasive environments. In particular, the research describes the approach in the design and development of a context.aware framework for collaborative applications (CAFCA), utilizing user’s context social information for proactive adaptations in pervasive environments. In order to validate the proposed framework an evaluation was conducted with a group of users based on enterprise scenario. The analysis enabled to verify the impact of the framework in terms of functionality and efficiency in real-world conditions. The main contribution of this thesis was to provide a context-aware framework to support collaborative applications in pervasive environments. The research focused on providing an innovative socio-technical approach to exploit collaboration in pervasive communities. Finally, the main results reside in social matching capabilities for session formation, communication and coordinations of groupware for collaborative activities.

Evaluation of online higher education: learning, interaction and technology

The work presents a theoretical framework for the evaluation of e-Teaching that aims at positioning the online activities designed and developed by the teacher as to the Learning, Interaction and Technology Dimensions. The theoretical research that underlies the study was developed reflecting current thinking on the promotion of quality of teaching and of the integration of information and communication tools into the curriculum in Higher Education (HE), i.e., bearing in mind some European guidelines and policies on this subject. This way, an answer was sought to be given to one of the aims put forward in this study, namely to contribute towards the development of a conceptual framework to support research on evaluation of e-teaching in the context of HE. Based on the theoretical research carried out, an evaluation tool (SCAI) was designed, which integrates the two questionnaires developed to collect the teachers' and the students' perceptions regarding the development of e-activities. Consequently, an empirical study was structured and carried out, allowing SCAI tool to be tested and validated in real cases. From the comparison of the theoretical framework established and the analysis of the data obtained, we found that the differences in teaching should be valued and seen as assets by HE institutions rather than annihilated in a globalizing perspective.
