A systematic approach for energy-efficient design of rolling bearing cages
Gaydamaka, Anatoliy; Klitnoi, Volodymyr; Dobrotvorskiy, Sergey; Basova, Yevheniia; Matos, Demétrio Ferreira; Machado, JoséSeveral aspects must be considered in the design of rolling bearing cages. One of the most important considerations relates to studying and developing a stationary approach for solving problems of heat and mass transfer during convection. In this context, this paper proposes, among other achievements, the development and validation of a model of heat generation that is used, as the basis for an energy-efficient...
A platform toy for children with special educational needs
Ferreira, Rosária; Matos, Demétrio Ferreira; Carvalho, Vítor; Soares, FilomenaIn childhood, play is critical to the successful development of children, and it can be regarded as the most important activity in their daily life, allowing interaction and discovery of the world around them.

Design and testing of a textile EMG sensor for prosthetic control
Arruda, Luisa M.; Calado, Alexandre; Boldt, Rachel S.; Yu, Yao; Carvalho, Helder; Carvalho, Miguel; Ferreira, Fernando; Soares, FilomenaNowadays, Electromyography (EMG) signals generated by the amputee’s residual limbs are widely used for the control of myoelectric prostheses, usually with the aid of pattern-recognition algorithms. Since myoelectric prostheses are wearable medical devices, the sensors that integrate them should be appropriate for the users’ daily life, meeting the requirements of lightness, flexibility, greater motion identific...
Development of a serious game to fight childhood obesity: "barty"
Goncalves, Fatima; Carvalho, Vitor; Matos, Demétrio Ferreira; Soares, FilomenaSerious games are often used for the purpose of educating through fun. This serious game, designed for Android devices, includes three challenges that are presented randomly to the player. The main objective of game is to teach the player to classify food in terms of healthiness and to teach the proper food to eat over the different day meals. The evaluation of the challenges takes into account its time and the...
Mechatronic system for the promotion of physical activity in people with motor ...
Pereira, Leandro; Machado, José; Carvalho, Vítor; Soares, Filomena; Matos, Demétrio FerreiraThis work presents the initial step of the development of a mechatronic system that aims to promote physical activity in people with motor limitations. This mechatronic system consists of a stationary bike similar to the current gym bikes, with the difference of having a didactic component. The didactic component presents the integration of a game that simulates a paramotor in which the speed of pedalling allow...
A supervised autonomous approach for robot intervention with children with auti...
Silva, Vinicius Corrêa Alves; Queirós, Sandro Filipe Monteiro; Soares, Filomena; Esteves, João Sena; Matos, Demétrio FerreiraTechnological solutions such as social robots and Objects based on Playware Technology (OPT) have been used in context of intervention with children with Autism Spectrum Disorder (ASD). Very often in these systems, the social robot is being fully controlled using the Wizard of Woz (WoZ) method. Although reliable, this method increases the cognitive workload on the human operator. They have to pay attention to t...
Design of a biomedical kit for bedridden patients: a conceptual approach
Moreira, Filipe; Matos, Demétrio Ferreira; Carvalho, Vitor; Soares, FilomenaConsidering an Ambient Assisted Living context, it is proposed to design a system/equipment that allows the support of bedridden patients who require continuous or palliative medical care through a Medical Care Module (MCM) operated by a single person. The system should allow the autonomy, comfort, and safety of bedridden patients, in the scope of home care. During the development of the MCM, different biomedic...
