This thesis focuses on the estimation of rubber tube wall compliance using a pulse echo-acoustic reflectometry technique. Five rubber latex tubes of different thicknesses were studied using a transient acoustic pulse, ...

A common problem when using a hearing aid is the accumulation of earwax, dust and water in the conduit that transmits the sound towards the ear. Hearing aids are damaged when unqualified people try to remove these foreign ...

Although the exact pathways leading to cell killing during hyperthermia are still not fully understood, it appears that protein denaturation is crucial in such process. To determine if the manner in which the magnetic field ...

Nine polyvinylidene fluoride (PVDF) membrane transducers were developed to be used as receivers and transmitters in underwater applications, such as in acoustic reflectometry. The design requirements were oriented to comply ...

Time domain acoustic reflectometry is proposed in this research as a method to detect atherosclerosis, estimating the location and extension of arterial obstructions by determining what is ahead of the catheter tip (“forward ...

Magnetic fluid hyperthermia (MFH) is a non-invasive cancer treatment in which magnetic nanoparticles are administered to cancerous tissues. This raises the temperature of the affected region above a certain threshold ...

Development and improvement of instruments used to characterize magnetic materials is one of the most important tasks in science, which could lead to relevant studies in material science and engineering. The AC magnetic ...

Detection and estimation of obstructions located in liquid-filled tubes is a major concern that ranges from oil industries to medical applications. In the medical devices field, the obstruction detection and estimation ...

Electrical studies of cross-linked methacrylic acid hydrogels molecularly imprinted with hydrocortisone were conducted by means of electrical resistivity estimates. A factorial experimental design method was followed to ...
