Excessive vibration of nuclear reactor components, such as the heat exchanger or the fuel assembly should be avoided as these can compromise the lifetime of these components and potentially lead to safety hazards. This issue is particularly relevant to ne... see more

In this work, we interested to utilize Fiber Bragg Grating (FBG) for monitoring sound intensity level. Acoustic disturbance could induce strain and changing the refractive index of FBG. Therefore, light will interfere for the trough of transmission at one... see more

The present paper will discuss the work in progress at the Department of Physics of the University of Pisa in collaborationwith the IFAC laboratory of CNR in Florence to develop pressure sensors with outstanding sensitivityin the acoustic and ultrasonic r... see more

This paper presents the achievements and progress made on the polymer optical fiber (POF) gratings inscription in different types of Fiber Bragg Gratings (FBGs) and long period gratings (LPGs). Since the first demonstration of POFBGs in 1999, significant ... see more

We experimentally and theoretically investigate the band-gap and transmission properties of phononic crystal (PC) beams immersed in water. Spectral element method (SEM) is developed for theoretical analysis in which the hydrodynamic loading is taken into ... see more

Thermal and pressure stability of Li-ion batteries (LiB) are the most important parameters for safety. In abuse operating conditions, the rapid increase of temperature and pressure can cause the appearance of hot-spots, which may lead to an increasing deg... see more

Conocer el comportamiento real de una estructura de hormigón armado es difícil. debido a los múltiples factores que influyen en el mismo. La heterogeneidad del hormigón y la evolución de sus características mecánicas y físicas a lo largo de la vida útil d... see more
