1. Electromechanical Impedance - Based Structural Health Monitoring Instrumentation System Applied to Aircraft Structures and Employing a Multiplexed Sensor Array
ABSTRACT: The electromechanical impedance method has been seen as a promising tool for structural health monitoring regarding different types of structures and purposes. Most importantly, this method can be used in real-time applications. Frequently, massive, high-cost, single-channel impedance analyzers are used to process the time domain data, aiming at ob

2. A novel method for EMG decomposition based on matched filters
Introduction Decomposition of electromyography (EMG) signals into the constituent motor unit action potentials (MUAPs) can allow for deeper insights into the underlying processes associated with the neuromuscular system. The vast majority of the methods for EMG decomposition found in the literature depend on complex algorithms and specific instrumentation.

3. Acionamento de dispositivos robóticos através de interface natural em realidade aumentada / Robotic device actuation through natural interface in augmented reality
Since the beginning of History and particularly of the Industrial Revolution, human beings have sought to replace or supplement their workforce with devices and machines, in order to expand their productive capacity or to solve tasks for which the use of human power is not satisfactory or it is dangerous. This need pushed the development of robotic devices i

4. UM ESTUDO SOBRE RESERVA DE RECURSOS COMPUTACIONAIS NO NÍVEL DO USUÁRIO / A STUDY ON COMPUTACIONAL RESOURCE RESERVATION AT USER LEVEL
The way computing is done today is changing as a result of the everincreasing processing, storage, and communication capacities of modern computer hardware. Resource sharing scenarios, in which a physical server is shared for different applications, are becoming much more common. These scenarios require special attention to guarantee that the performance iso

5. Arquitetura modular de processador multicore, flexível, segura e tolerante a falhas, para sistemas embarcados ciberfísicos. / Modular multicore processor architecture, flexible, securi and fault tolerant, to embedded cyber-physical systems.
Cyber-physical Systems (CPS) are systems where there is an union between computing and physics. The CPS will be used in several areas, forming a new era of systems or devices and could be anywhere, being used by anyone and anything. Applications for CPS include highly reliable medical systems and devices, traffic control and security, advanced automotive, pr

6. Development of an Acquisition System and Data Analysis for Measurements of Electron Transport Parameters in Gases / Desenvolvimento de sistema de aquisição e tratamento de dados para medidas de parâmetros de transporte de elétrons em gases
This thesis describes a pulsed Townsend experiment whose purpose was to obtain experimentally the transport parameters of electron in gases, particularly nitrogen and isobutane, within a range of reduced electric field between 130 Td and 210 Td. The transport parameters obtained were the average speed of center of mass of the electron cloud, the ionization r

8. AvaliaÃÃo dos parÃmetros dosimÃtricos em feixes de FÃtons de Radioterapia usando fototransistor SMT
One of the biggest challenges in radiotherapy dosimetry is to certify that the prescribed dose is given to the patient. For this, it is necessary to use small detectors to evaluate the beam parameters. Current dosimetry is realized with detectors that highlight problems: high cost, difficulty in handling, absence of real time readout, complex and delayed obt

10. Development of a computacional model for calculations of absorved dose to organs and tissues of the human body in situations of accidental exposures / Desenvolvimento de um modelo computacional para cÃlculos de dose absorvida em ÃrgÃos e tecidos do corpo humano nas situaÃÃes de exposiÃÃes acidentais
Exposure to a radiation field may be of medical, environmental, occupational or accidental nature, but in all cases the main objective is the determination of the whole body absorbed dose or the distribution of absorbed dose to specific organs and tissues. In recent years, estimates of the radiation absorbed dose in the human body have become more accurate d

11. Implantação de um sistema de detecção de vazamentos em oleodutos com tratamento de alarmes falsos
The pumping of fluids in pipelines is the most economic and safe form of transporting fluids. That explains why in Europe there was in 1999 about 30.000 Km [7] of pipelines of several diameters, transporting millíons of cubic meters of crude oil end refined products, belonging to COCAWE (assaciation of companies of petroleum of Europe for health, environmen

12. ConstruÃÃo de um nariz artificial usando redes neurais
The animals interact with environment in several ways. The smell around them has an extremely importance in the information transport, essential for survival. Such as for the animals, the smell plays an important rule for human beings. Due to this importance, the study in the human olfactory system is very helpful and started very long time ago. Although it
