Electrical impedance tomography (EIT) consists in probing biological tissues with low amplitude alternating electrical fields through surface electrodes, and analyzing the response of the medium to reconstruct its electrical characteristics. EIT has been considered for a wide range of clinical applications, the most promising being continuous pulmonary function monitoring. In the EIT reconstruc...

In this study, the thermal analysis of an aluminum piston coated with MgOZrO2 to create a barrier COMSOL multiphysics program and changes in exhaust gas temperature, fuel consumption, engine torque values obtained as result test experiments were examined. For purpose, uncoated was started biodiesel 5% water + 15% ethanol doped at speeds 1000 rpm, 1500 2000 2500 rpm. results COMSOL, it found tha...

Abstract In the present study, computing techniques are designated and employed in order to analyze “quorum sensing” as a special case of cell-to-cell bacterial communication attributed Pseudomonas genus. One challenges consists predicting concentration key substances characterizing level” during population dynamics. To estimate relevant characteristics communication, we applied deterministic a...

Electromagnetic radiation can be produced using functional materials such as magnetoelectric (ME) composites, in which the magnetoelasticity and piezoelasticity of material are involved. The mechanical nature vibrations is used to miniaturize ME antenna micro-scale size. performance evaluation requires a multiphysics analysis structure. An design simulation detailed finite element method (FEM) ...

A compact, ultrahigh vacuum, radiative heater based on pyrolytic boron nitride that efficiently directs nearly all of its radiation to the sample was designed and constructed. It is shown reaches temperatures 1300 K experimentally at 60% maximum power. COMSOL Multiphysics® simulation an analytical model predict ultimate temperature up 1500 K. Furthermore, does not introduce any contamination sa...
