Estimates of methane loss and energy recovery potential in anaerobic reactors treating domestic wastewater.
This work aimed at developing a mathematical model that could estimate more precisely the fraction of chemical oxygen demand (COD) recovered as methane in the biogas and which, effectively,Expand

Influence of different boundary conditions at the tympanic annulus on finite element models of the human middle ear
The tympanic annulus is a fibrocartilage ligament that supports the tympanic membrane in a sulcus at the end of the outer ear canal. Among many FE models of the middle ear found in literature, theExpand

Analysis of the effect of different patologies on the sound transmission through the middle ear by means of a finite-element model
The middle ear is part of the human auditory system and its function is to transmit acoustical energy to the inner ear by means of mechanical vibrations. Finite-Element (FE) models of the humanExpand
Analysis of different modeling approaches of the cochlea impedance in FE models of the human middle ear
Finite element models of the human middle ear are important tools in the development of implantable hearing aids or to study the impact of surgeries on middle ear dynamics. Thus, the cochleaExpand
Numerical and experimental analysis for the construction of an in situ measurement system of the acoustic impedance to be used as an academic tool
Due to the need for a non-destructive method to measure sound absorption of acoustic materials, in situ methods have achieved significance in research on acoustic. So, the goal of this work is toExpand
