Communicating Intent as Behaviour Trees for Decentralised Multi-Robot Coordination

We propose a decentralised multi robot coordination algorithm that features a rich representation for encoding and communicating each robot s intent This representation for intent messages enables improved coordination behaviour and communication efficiency in difficult scenarios such as those where there are unknown points of contention that require negotiation between robots Each intent message is an adaptive policy that conditions on identified points of contention that conflict with the intentions of other robots These policies are concisely expressed as behaviour trees via algebraic logic simplification and are interpretable by robot teammates and human operators We propose this intent representation in the context of the Dec MCTS online planning algorithm for decentralised coordination We present results for a generalised multi robot orienteering domain that show improved plan convergence and coordination performance over standard Dec MCTS enabled by the intent representation s ability to encode and facilitate negotiation over points of contentio

How to communicate a new fashion brand through social media and public relations’ perspective

Fashion communication has been undergoing a transformation and there is a drop in tradicional marketing investments which indicates new modalities of brand’s communication. The purpose of this study is to discuss the branding strategy relevance through social media and public relations’ perspective, aiming to understand how digital marketing platforms have been used and integrated by new fashion brands. This paper presents an ongoing Master’s research including data collection method through a qualitative content analysis, aiming to find some features can contributed to improve their market position.COMPETE and by national funds through FCT – Foundation for Science and Technology within the scope of the project POCI-01-0145-FEDER-007136”.info:eu-repo/semantics/publishedVersio

O conhecimento de polígonos e poliedros: uma análise do desempenho de alunos do ensino médio em exemplos e não-exemplos

O artigo pretende mostrar os resultados de uma pesquisa cujo objetivo foi analisar o desempenho de alunos do Ensino Médio na identificação de exemplos e não-exemplos de polígonos e poliedros, tendo em vista os atributos definidores e atributos irrelevantes. Participaram da pesquisa 253 alunos, distribuídos em três séries do Ensino Médio de uma escola pública, que responderam um teste de exemplos e não-exemplos. Posteriormente, foram selecionados seis alunos para serem entrevistados sobre seus conhecimentos a respeito dos exemplos e não-exemplos. Os resultados mostraram que os participantes obtiveram uma média baixa (M = 5,59) na tarefa que exigiu a identificação de exemplos e não-exemplos de polígonos e poliedros. A análise das entrevistas mostrou que a maioria dos alunos considerou que o atributo irrelevante dos polígonos analisados não interferiu na resposta. Contudo, evidencia-se, de modo geral, que esses alunos apresentaram um conhecimento conceitual longe do esperado para esse nível de ensino.The article intends to show the results of research whose objective was to analyse the performance of students from High School in the identification of examples and non-examples of polygons and polyhedrons, intending to define the attributes and irrelevant attributes. In the research 253 students participated distributed into three series from High School in public school who answered a test of examples and non-examples. Later, six students were selected to be interviewed about their knowledge of examples and non-examples. The results showed that the participants had low average (M = 5,59) in the homework which demanded the identification of examples and non-examples of polygons and polyhedrons. The analysis of the interviews showed that the most students considered that the irrelevant attribute of polygons analyzed did not interfere in the response. However, it is evident, in general, that these students presented a conceptual knowledge far from the expected for level of education
