Hierarchization process by possibilistic fuzzy clustering of fuzzy rules
Salgado, Paulo; Cunha, Manuela; Pavão, João; Igrejas, GetúlioThis paper presents a possibilistic fuzzy clustering algorithm that is applied to a multidimensional fuzzy set or fuzzy rules. This method can be used to decompose the fuzzy system into an hierarchical structure. The methodology presented leads to a fuzzy partition of the fuzzy rules, one for each cluster, which corresponds to a new set of fuzzy sub-systems. This technique is tested to organize the fuzzy model ...
Benefícios do exercício físico na insuficiência cardíaca descompensada: uma rev...
Martins, Marlene de Fátima Gomes FernandesEsta revisão sistemática da literatura aborda a temática do exercício físico em doentes com insuficiência cardíaca descompensada, definindo os benefícios que este exerce sobre a capacidade funcional, qualidade de vida, função cognitiva e taxas de reinternamento e mortalidade. Pergunta de Investigação: “Quais os benefícios do exercício físico em doentes com insuficiência cardíaca descompensada?” Objetivos: ident...
Seismic response reduction of building structures using a semi-active control s...
Braz-César, Manuel; Barros, RuiThe present paper investigates the effectiveness of a bio-inspired semi-active controller to reduce seismic-induced vibrations in building structures. The control system is based on the use of a MR damper in combination with the so-called Brain emotional learning based intelligent controller (BELBIC), which is an intelligent controller based on the model of Limbic system of brain. A general case for a three deg...
3D Simulator with hardware-in-the-loop capability for the micromouse competition
Piardi, Luis; Eckert, Lucas; Lima, José; Costa, Paulo Gomes da; Valente, António; Nakano, Alberto YoshiroRobotics competitions are a way to challenge researchers, roboticists and enthusiastic to address robot applications. One of the well-known international competition is the Micromouse where the fastest mobile robot to solve a maze is the winner. There are several topics addressed in this competition such as robot prototyping, control, electronics, path planning, optimization, among others while keeping the size...
Building of smart plugs to energy efficiency in the residence load management
Silva, William Rodrigues; Brito, Thadeu; Gambôa, Luis; Lima, JoséIt is known that electrical energy consumption is higher during the day than at night.This is a challenge to balance the consumption levels because when the consumption is high at night, it does not have energy production to supply and the tariff usage is cheaper. Aspiring to avoid the users consuming too much electrical energy and work on this usage control during the night, the present work aims to develop sm...
Intensidade de pastejo e épocas de aplicação de adubação nitrogenada sobre a pr...
Rodrigues, Rute Manuela dos SantosO gerenciamento de pastagens é o fator-chave dos sistemas integração lavoura-pecuária (ILP), sendo necessário entender o crescimento de plantas e animais. O fertilizante nitrogenado é outro fator importante para ILP, porque a disponibilidade deste nutriente controla os processos de fluxo e composição química dos tecidos. Dentro deste breve contexto, experimentos realizados para avaliar aspectos relacionados à i...
A real framework to apply collaborative robots in upper limb rehabilitation
Fernandes, Lucas de Azevedo; Brito, Thadeu; Piardi, Luis; Lima, José; Leitão, PauloRehabilitation is an important recovery process from dysfunctions that improves the patient’s activities of daily living. On the other hand, collaborative robotic applications, where humans and machines can share the same space, are increasing once it allows splitting a task between the accuracy of a robot and the ability and flexibility of a human. This paper describes an innovative approach that uses a collab...
Key parameters when developing carbonaceous materials for catalytic wet peroxid...
Ribeiro, Rui; Silva, Adrián; Pastrana-Martínez, Luisa; Figueiredo, José; Faria, Joaquim; Gomes, HelderCatalytic wet peroxide oxidation (CWPO) is an advanced oxidation process, operated using simple equipment and mild operating conditians, in which highly oxidizing hydraxyl radicaIs (HO') are generated fram the catalytic decompasition af hydrogen peroxide (H,O,) [L 2). Sinee the report of Lüeking el ai. in 1998 [3], the develapment af suitab-Ie -carbonaceous materials (without any added metal phase) for CWPO has...
Avaliação térmica provocada pela furação no tecido ósseo
Sampaio, Cátia S.T.; Fonseca, E.M.M.; Cerqueira, Rui; Ferreira, NelsonEste trabalho tem como objetivo avaliar o efeito da temperatura no osso devido ao aquecimento provocado pelo processo de furação. Foram realizadas visitas a duas clínicas para acompanhamento da técnica de implantologia dentária e recolhidas imagens termográficas para a leitura da temperatura gerada na broca após o processo de furação. Na colocação de implantes dentários por exemplo, as variáveis que interferem ...
Efecto del peso al sacrificio y de la raza en la calidad instrumental y sensori...
Ripoll, Guillermo; Alcalde, Maria Jesús; Horcada-Ibáñez, Alberto; Sañudo, Carlos; Teixeira, Alfredo; Panea, BegoñaSe utilizaron 141 cabritos de 5 razas españolas a dos pesos de sacrificio y se determinó la calidad instrumental y sensorial de su carne. La influencia del peso al sacrificio es, presumiblemente, muy importante sobre la calidad de la carne, pero este efecto debe ser valorado para cada raza. Aunque la carne del cabrito más ligero tuvo mayores valores en la fuerza de compresión, en el análisis sensorial esta carn...
