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...

U radu su predstavljene opšte karakteri­stike elektroenergetskih sistema sa osvrtom na primenu bakarnih šinskih provodnika u razvodnim postrojenjima. Prikazani rezultati proračuna magnetskog polja, gustine struje i toplotnih efekata kao dela trofaznog sistema. Simulacija je rađena COMSOL Multiphysics 5.5 programskom paketu koji numeričkim putem rešava parcijalne diferencijalne jednačine primeno...

In this paper, the shape influence of piezoelectric beams including triangle, trapezoid, rectangle, inverted trapezoid, convex parabola, concave parabola, and comb-shaped (a combination of two triangular beams with a connector of 4 mm length) are addressed and analyzed by FEM. The analysis is performed for a bimorph piezoelectric beam. The analyzed parameters include the beam length, thickness ...

A two-dimensional CFD model of a planar solid oxide fuel cell (SOFC) has been developed.This model can predict the performance of SOFC at various operating and design conditions.The effect of Knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. The mathematical model solves conservation of electrons and ions and conservation ofspecies. The model is formulate...
