The Biomedical Engineering (BE) is an interdisciplinary area that employs knowledge and methods of Math and Sciences to investigate and solve problems of Medicine and Biology. In the PPGEE (Electrical Engineering Post-graduation Program), the BE conducts research, mainly, in biomedical instrumentation and signal processing applied to the study of the cardiac, respiratory and nervous systems. Devices for basic research and medical/hospital equipment including technological innovation are implemented. Mathematical methods are applied aiming at extracting relevant information about physiological systems and human health. The currently investigated themes encompass brain-computer-brain interfaces, mental practices for patient neuro-rehabilitation, analysis of the brain electrical activities related to cognitive and sensorial systems - including steady-state auditory, visual and somatosensory (by current pulses or temperature) evoked potentials - cellular mechanisms of visual perception, pupillometry, heart rate variability, maximum respiratory pressures. It is worth noting that the Biomedical Engineering in the PPGEE involves graduates from different areas such as Engineering (electrical, electronic, automation and control, mechanical, civil), Physics, Computer Science, Biology, Medicine, Physiotherapy, Phonoaudiology, Physical Education, Psychology, and Linguistics. Such characteristics make the BE of the PPGEE a plural and fertile ground for the emergence of new devices/inventions.
Alessandro BedaThe Cyberphysical Systems Control and Modeling research line dialogues with different areas of engineering research by proposing innovative solutions for the control and modeling of networked interconnected systems integrating digital technologies and physical agents. The research topics covered are: system identification; robust control via optimization; network control; cybersecurity and control; cooperative control for multi-agents; distributed control; fuzzy control; control by learning; data-driven control; adaptive control; fault detection, diagnosis and prognosis; fault tolerant control; control of nonlinear systems; non-linear signal processing and analysis; state estimation; sensor fusion; development of virtual sensors; and related topics. A characteristic of most of the work carried out in the line is the combination of sophisticated techniques, with significant theoretical challenges, and their application in solving practical problems in the most diverse areas, including aeronautics, robotics, petrochemistry, multi-agent coordination, synchronization of energy sources, biomedicine, among others.
Bruno Otávio Soares TeixeiraThe automatic control of industrial processes, robots and dynamical systems in general is the main objective in this line of research. Nowadays automation strategies have grown in importance due to the increasing demand on energy efficiency improvement, reduction of fresh raw materials consumption and emission of pollutants, together with life quality enhancement based on the intensive use of automatic mechanisms to effect tasks that are repetitive, or should be performed with great accuracy, or simply cannot be done by humans. In this context, new synthesis methods for controllers and robotic systems together with stability and performance analysis techniques have been proposed in this research line by considering practical aspects, such as process uncertainties, measurement noise, occurrence of failures, and presence of time delays.
Armando Alves NetoThis research line, integrated in the area of Computer Systems, was installed in 2009 with the objective to leverage the field of microelectronics and microsystems in the PPGEE. The intention of MeMs is the formation of high qualified human resources and research following international standards. The research line is engaged with the development, fabrication, and verification of integrated circuits and microsystems. Thereby, the activities of the members include projects related to optronics and image sensors, applied micro- and nanoelectronics, development of integrated systems, as well as metrology. Further, several members are integrated in the INCT-DISSE for semiconductor nanodevices, and collaborate directly with the INCT-NAMITEC for nano- and microtechnologies. More information about participating laboratories can be found here: OptMAlab, PSE.
Ado Jorio de VasconcelosThe activities of the Antennas, Radio Wave Propagation and Applied Electromagnetism (APE) research line are aimed at teaching, research and extension in the areas of Telecommunications and Applied Electromagnetism, aiming at the application of electromagnetic theory in engineering problems involving synthesis and analysis of antennas, microwave devices, characterization of radioelectric propagation and the radio channel, performance prediction of wireless communication systems, design of electromagnetic machines and devices and non-destructive testing. Problems involving electromagnetic fields coupled to other physical systems are also worked on, such as inductive or microwave heating processes, fields in biological systems, etc. The line's activities also include the creation of theoretical and numerical tooling dedicated to solving these problems, using techniques such as finite element methods (traditional and generalized), finite differences, method of moments, meshless methods and boundary elements.
