Particle swarm-based olfactory guided search
Marques, Lino; Nunes, Urbano; Almeida, A. deAbstract This article presents a new algorithm for searching odour sources across large search spaces with groups of mobile robots. The proposed algorithm is inspired in the particle swarm optimization (PSO) method. In this method, the search space is sampled by dynamic particles that use their knowledge about the previous sampled space and share this knowledge with other neighbour searching particles allowing...
Olfactory coordinated area coverage
Larionova, Svetlana; Almeida, Nuno; Marques, Lino; Almeida, A. deAbstract This paper proposes an olfaction based methodology to automatically cover an unknown area enabling the decoupled cooperation of a group of floor cleaning mobile robots. This method is based on the utilisation of low cost chemical sensors in cleaning mobile robots, in order to differentiate clean from dirty areas. The experimental results show that the use of olfactory capabilities allows to efficientl...
Multisensor Demining Robot
Rachkov, Michael Yu.; Marques, Lino; Almeida, Aníbal T. deThe paper describes an advanced multisensor demining robot. The robot transport system is based on a simple structure using pneumatic drive elements. The robot has robust design and can carry demining equipment up to 100 kg over rough terrains. Due to the adaptive possibilities of pedipulators to obstacles, the robot can adjust the working position of the demining sensors while searching for mines. The detectio...

Margarete Marques LinoThis study aimed to investigate quality of life and job satisfaction among intensive care nurses and to examine its relationships. The sample consisted of 190 intensive care nurses, representing 19 Intensive Care Units (ICUs). A self-administered questionnaire was used to collect sociodemographic, occupational, health data, perceptions and states of life and work. The generic version of Quality of Life Index (Q...
Olfaction-based mobile robot navigation
Marques, Lino; Nunes, Urbano; Almeida, Aníbal T. deIt is well known that insects and other animals use olfactory senses in a wide variety of behavioural processes, namely to recognize and locate food sources, detect predators, and find mates. This article discusses the gathering of olfactive information and its utilization by a mobile robot to find a specific odour source in a room with turbulent phenomena's and multiple sources of odour. Three navigation algor...
Satisfação profissional entre enfermeiras de UTI: adaptação transcultural do In...
Margarete Marques LinoSatisfação profissional é um fenômeno complexo e multivariado, vivenciado pelos indivíduos como um estado comportamental derivado de fontes internas e externas. Considerando o ambiente das Unidades de Terapia Intensiva (UTIs) como fontes geradoras de estímulos externos - positivos e negativos, é essencial uma investigação sistemática para examinar o nível de satisfação das enfermeiras de terapia intensiva em re...
