The otoacoustic emissions (OAEs) are acoustic signals emitted by the inner ear as a consequence of the activity of a nonlinear feedback mechanism capable of amplifying the signal near to the hearing threshold level. The otoacoustic emissions can be used as an acoustic imaging of the cochlear functionality. They are used in clinics for screening purposes but due to the extreme variability ...

Bone resorption around hip stems, in particular periprosthetic bone loss, is a common observation post-operatively. A number of factors influence the amount of bone loss over time and the mechanical environment following total hip replacement (THR) is important. Conventional long stem prostheses have been shown to transfer loads distally, resulting in bone loss of the proximal femur. More ...

The MEMS microphone is also called microphone chip or silicon microphone.The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone design. The device consists of a polysilicon diaphragm suspended over a single crystal silicon backplate ...

Multiphysics simulation was used in this work to model inductively coupled plasmas (ICPs). Developing a model of an ICP is challenging due to the complex relationship between the applied electric field and mixture of chemical species that develops. A preliminary model was developed and validated for an Ar/O2 plasma including neutral, ionic, and all major reactions. The validated model was used ...

Proton exchange membrane fuel cells (PEMFCs) were investigated using COMSOL Multiphysics with the AC/DC Module and Chemical Engineering Module. Simulation may be used to increase the performance while decreasing the cost of the catalyst later (CL). Experimental validation of single and multi-layer CL was performed for varied PBI electrolyte content. The validated model was used to investigate ...

In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using COMSOL Multiphysics®, for solving the equations of heat transfer (conduction and convection) and those of fluid ...

Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is developed to simulate the microwave drying process. An elaborate experimental system comprising of infrared ...

This study deals with the 3D modeling of a light photocatalytic textile. This process aims to decontaminate industrial effluents such as water with pesticides. The present study describes the implementation of a reactive transport model in a computational fluid dynamics model developed on a Representative Volume Element (RVE) of the textile, i.e. at the microscopic scale. The final ...

Electrocoalescence is the phenomenon of coalescence of droplets suspended in an insulating liquid or in a gas under the action of an electric field. Electrocoalescence is considered a promising tool in many petrochemical industries for desalting crude oils. However, this technique suffers from some drawbacks such as short circuiting of electrodes, limitations on applied electric field and its ...
