4. MONITORING FLEXIBLE RISERS WITH OPTICAL FIBER SENSORS / MONITORAMENTO DE RISERS FLEXÍVEIS COM SENSORES A FIBRA ÓPTICA
The interest in structural health monitoring of flexible risers has grown significantly in recent years. For ducts that are already reaching their design life, monitoring systems can provide early warnings of potential failures and also assist the operator in scheduling downtime. Different techniques are being tested by operators of flexible pipes such as au

5. Perception and production of speech in a hearing impaired child during therapy / Percepção e produção de sons de fala em uma criança com deficiência auditiva em terapia fonoaudiológica
Introduction: Very few studies discuss speech development in hearing impaired children in the first years of life due to methodological difficulties and the number of variables involved. Acoustic inspection of articulatory adjustments and attempts to imitate a model made by the infant in different contexts can be a method to comprehend the manner in which fi

8. Desenvolvimento de técnicas para avaliação de combustíveis nucleares tipo placa pelo método de ensaio por ultra-som
One of the most important steps in the fabrication processes of plate type nuclear fuels, intended to be used in research reactors or naval propulsion, is the development of nondestructive testing (NDT) methods and techniques for their quality assessment during fabrication and post-irradiation analysis. Those tests can contribute to detect discontinuities su

10. EFEITO DA PRÁTICA MUSICAL NO PROCESSAMENTO AUDITIVO EM ESCOLARES DE SETE A 14 ANOS DE IDADE / EFFECT OF THE MUSICAL LEARNING IN THE HEARING PROCESSING IN SCHOLARS FROM SEVEN TO FOURTEEN YEARS OLD
It is known that the understanding of the speech is essential for a normal communication and it is dependent of the hearing abilities. Such abilities, among others, are fundamental for the understanding of the acoustic information, they depend on the perceptive ability of the sounds and each person s individual capacity. The capacity of acoustic interpretati

12. DEVELOPMENT OF PIGS TO DETECT AND LOCATE SMALL PIPELINES LEAKS / DESENVOLVIMENTO DE PIGS INSTRUMENTADOS PARA DETECÇÃO E LOCALIZAÇÃO DE PEQUENOS VAZAMENTOS EM DUTOS
This work´s objective is the development of inspections tools capable to detect and locate small leaks in gas and oil pipelines. Nowadays, many brazilian pipelines are equipped with reliable leak detection systems, but these still can`t detect small leaks caused by slow corrosion processes. The most used pipeline inspection technology is the instrumented pi
