Guia de Boas Práticas para a manutenção de Faixas de Gestão de Combustível
Folgôa Batista, Maria Teresa; Moreira, André; Afonso, José; Lopes, Inês; Querido, Cassandra; Freire, António; Marques, Pedro; Rocha, IsildaA preservação da Floresta, ao nível dos ecossistemas e dos recursos existentes, passa pela construção de uma estratégia de defesa contra os incêndios, aliada à proteção das espécies, respeitando a biodiversidade da região onde se executa a gestão de combustível, não obstante o cumprimento da legislação que define os critérios para a execução das faixas de gestão de combustível.Neste sentido, este manuel pretend...
An ontological model for fire evacuation route recommendation in buildings
Neto, Joaquim; Morais, A. Jorge; Gonçalves, Ramiro Manuel Ramos Moreira; Coelho, António LeçaGuiding the occupants of a building to a safe place is an area of research that deserves the attention of researchers. Finding solutions for the problem of guiding the building occupants requires a perfect knowledge of the fire building evacuation domain. The use of ontologies to model the knowledge of a domain allows a common and shared understanding of that domain. This paper presents an ontology that has the...
Geometric and physical building representation and occupant’s movement models f...
Neto, Joaquim; Morais, A. Jorge; Gonçalves, Ramiro Manuel Ramos Moreira; Coelho, António LeçaBuilding evacuation simulation allows for a better assessment of fire safety conditions in existing buildings, which is why it is of interest to develop an easy-to-use web platform that helps fire safety technicians in this assessment. To achieve this goal, the geometric and physical representation of the building and installed fire safety devices are necessary, as well as the modelling of occupant movement. Al...
Comparação entre Segmentação Automática do Disco Ótico por SD-OCT e Retinografi...
Simão, Jorge; Raimundo, Miguel; Pereira, Pedro; Faria, Pedro; Moura Pereira, José; Neto, JoaquimINTRODUÇÃO : O rácio estimado entre os diâmetros verticais ou horizontais do disco com a escavação do mesmo (rácio escavação/disco – E/D), é uma das formas clássicas de presumir o dano neurológico glaucomatoso, sendo o hallmark histórico no diagnóstico e avaliação da progressão da doença. O objetivo deste estudo é comparar a avaliação automática dos parâmetros planimétricos do disco óti...
Aço Damasco: uma revisão da literatura
Neto, JoaquimO aço Damasco é um aço que desperta curiosidades não somente à primeira vista, pois não é simplesmente uma barra ou lamina de um aço qualquer com aparência de cor única em toda a sua extensão, mas sim se trata de um aço que possui desenhos e formas onduladas que entremeiam todo o aço, e essas formações onduladas nos trazem curiosidades, pois é um aço muito belo e desejável, sendo utilizado em facas funcionais, ...
An ontology for fire building evacuation
Neto, Joaquim; Morais, A. Jorge; Gonçalves, Ramiro Manuel Ramos Moreira; Coelho, António LeçaGuiding the building occupants under fire emergency to a safe place is an open research problem, and finding solutions to address the problem requires a perfect knowledge of the fire building evacuation domain. The use of ontologies to model knowledge of a domain allows a common and shared understanding of that domain, between people and heterogeneous systems. This paper presents an ontology that aims to build ...
Multi-agent-based recommender systems: a literature review
Neto, Joaquim; Morais, A. Jorge; Gonçalves, Ramiro Manuel Ramos Moreira; Coelho, António LeçaConsidering the growing volume of information and services available on the Web, it has become essential to provide Web sites and applications with tools, such as recommender systems, capable of helping their users to obtain the information and services appropriate to their interests. Due to the complexity of Web adaptation and the ability of multi-agent systems to deal with complex problems, the multi-agent sy...
Context-based multi-agent recommender system, supported on IoT, for guiding the...
Neto, Joaquim; Morais, A. Jorge; Gonçalves, Ramiro Manuel Ramos Moreira; Coelho, António LeçaThe evacuation of buildings in case of fire is a sensitive issue for civil society that also motivates the academic community to develop and study solutions to improve the efficiency of evacuating these spaces. The study of human behavior in fire emergencies has been one of the areas that have deserved the attention of researchers. However, this modeling of human behavior is difficult and complex because it dep...
Evaluating the performance and improving the usability of parallel and distribu...
Silva, Mateus; Meyer, Vinicius; Kirchoff, Dionatrã; Neto, Joaquim; Vieira, Renata; De Rose, CesarThe representation of words by means of vectors, also called Word Embeddings (WE), has been receiving great attention from the Natural Language Processing (NLP) field. WE models are able to express syntactic and semantic similarities, as well as relationships and contexts of words within a given corpus. Although the most popular implementations of WE algorithms present low scalability, there are new approaches ...
Implementation of neural networks to frontal electroencephalography for the ide...
Ferreira, Ana Isabel Leitão; Vide, Sérgio; Nunes, Catarina S.; Neto, Joaquim; Amorim, Pedro; Mendes, JoaquimObjective: General anesthesia is a reversible drug-induced state of altered arousal characterized by loss of responsiveness (LOR) due to brainstem inactivation. Precise identification of the LOR during the induction of general anesthesia is extremely important to provide personalized information on anesthetic requirements and could help maintain an adequate level of anesthesia throughout surgery, ensuring safe ...
