Shear wave elastography is an innovative technique used in combination with the traditional ultrasound imaging to improve the specificity of cancer imaging. A two-dimensional finite element model (FEM), composed of realistic boundary conditions, was developed in COMSOL Multiphysics® to ... Per saperne di più
A COMSOL Multiphysics® model was made to design a mechanical amplifier and radiation plate for the emission of high intensity 40.5 kHz ultrasound to air by means of a Langevin type transducer usually applied in cleaning baths for example. In this work, ultrasonic irradiation is aimed at ... Per saperne di più
Finite element analysis (FEA) is a modern tool for exploration of new horizons in science, technology and engineering. Different computer software such as ANSYS, ABACUS, PZFLEX and COMSOL Multiphysics® based on FEA are used for modeling and simulation of acoustic phenomena, for design of ... Per saperne di più
The variability of the design parameters caused by material properties like thermal conductivity is the major challenge in Micro Electromechanical System (MEMS). In resonator design the basic problem is that the frequency changes with temperature variation and quantitative explanation ... Per saperne di più
Despite of the existing successful clinical applications, however, the interaction, i.e. artificial sensing, between the robot and the patient is still very limited. With the help of various cameras, vision is almost the only feeling that a robot can have. In order to imitate the human ... Per saperne di più
Adulteration of automobile fuels, especially petrol and diesel is a rampant malpractice in India. With the rising prices of fuel and the subsidy on kerosene, getting away with even 10-15% adulteration is immensely profitable.To check adulteration effectively, it is necessary to monitor ...

This paper describes the COMSOL Multiphysics® simulation and the test of a low-frequency (500Hz) sound source for long-range acoustic communications. This design uses innovative carbon-fiber composite materials.To meet the demand for the frequency range the doubly resonant organ pipe ... Per saperne di più
Ultrasound is a promising green technology for the advanced oxidation process (AOP) since it adds no chemicals to the treated water. In this paper, COMSOL Multiphysics® was used as a tool to design and characterize an ultrasound irradiator with multi-stepped configuration, which aims to ... Per saperne di più
Sound absorption in porous materials with rigid frame and open porosity can be very effectively estimated by applying the Johnson-Allard model in order to substitute a porous medium with an equivalent effective fluid and then utilise the Helmholtz equation for time-harmonic acoustics. ...
