A União Europeia definiu metas para o combate ao desperdício alimentar com o objetivo de criar um mundo mais sustentável. Entre essas metas encontra-se a recolha seletiva de biorresíduos (resíduos orgânicos provenientes de atividades de jardinagem e da alimentação), que visa a sua valorização por, maioritariamente, dois processos – compostagem e digestão anaeróbia. Através destes processos é possível integrar o...
Alcântara (Lisbona), da quartiere industriale a destinazione turistica: offerta turistica, strutture ricettive e valutazione del quartiere.Nell’ambito dello sviluppo turistico che Lisbona sta vivendo negli ultimi anni, una delle aree emergenti è Alcântara, un ex quartiere industriale oggi in via di riconversione funzionale. Questo articolo tratta del processo di transizione di Alcântara da un tessuto economico ...
Cystoseira is a common brown algal genus widely distributed throughout the Atlantic and Mediterranean regions whose taxonomical assignment of specimens is often hampered by intra- and interspecific morphological variability. In this study, three mitochondrial regions, namely cytochrome oxidase subunit 1 (COI), 23S rDNA (23S), and 23S-tRNAVal intergenic spacer (mt-spacer) were used to analyse the phylogenetic re...
Social networks have allowed, over the past few years, the appearance of new ways to share opinions and ideas in texts, providing a basis for studying opinions on a large scale. The tools for the retrieval and analysis of sentiments, contained in this information, are still under development, limited by access restrictions and technical difficulties in the development of new methods, which involve natural langu...
In this paper we address the role of divergence and convergence in creative processes, and argue about the need to consider them in Computational Creativity research in the Genetic or Evolutionary Programming paradigm, being one ́s goal the problem of the Halt Condition in Genetic Programming. Here the candidate solutions are seen as evolutionary logic programs or theories, being the test whether a solution is ...
Intelligent agents configure a new generation of virtual entities that perform various autonomous tasks on behalf of others, namely the humans. On the other hand, the information society requires the development of new and more intelligent methods, tools and theories to analyse, define, model and specify agent-based systems. It is under this presupposition that in this work are introduced a pre-argumentative re...
The use of agents in Electronic Commerce environments leads to the necessity to introduce some formal analysis and definitions. A 4-step method is introduced for developing EC-directed agents, which are able to take into account non-linearites such as gratitude and agreement. Negotiations that take into account a multi-step exchange of arguments provide extra information, at each step, for the intervening agent...
The use of agent's technology in electronic commerce environments leads to the necessity to introduce some sort of formal attitude in the processes of software development and analysis. Logic programming and specially extended logic programming provides a powerful tool for achieving such goal; i.e., besides being mathematically correct it makes the prototyping phase easier. However, although no simple methodolo...
