Abstract

For individuals with conductive or mixed hearing loss, a bone conduction system can be a very effective treatment option. These systems bypass the outer and middle ear to send sound vibrations directly to the cochlea. This offers a natural sound quality for recipients. BONEBRIDGE is the first active, intact skin hearing implant for bone conduction stimulation, ideal for moderate to severe conduction hearing losses. It is a semi-implantable system, consisting of a surgical implantable part and an externally worn audio processor. Biomaterials used proved their safety, with very low rate of medical complications (skin infections, chronic suppurative otitis media, biofilm formation or extrusion).

Abstract

With the development of industry have made efforts to improve the performance of braking systems of motor vehicles on public roads. The choice of materials used for coupling brake system involved the development of new materials that meet safety requirements in circulation. During braking of any vehicle, due to the friction created between the disk and pad, temperature rise occurs with negative effects on the process of slowing down the vehicle. Mechanical and thermal stress being put on the brakes is very high. Due to overheating, brake discs and pads may warp or crack, and the material they are made may their change its structure. These defects give rise to vibrations and noise during braking, to reduce the coefficient of friction, reduce the effectiveness of the braking mechanism. This paper proposes a study regarding the thermal stresses effects of brake mechanism on the disc material of a car Dacia Logan. It proposes a theoretical model to calculate the temperature that occurred during the operation of the braking system and experimental analysis on the influence of temperature on the brake disc material.
