A microfluidic thermal cycler for Polymerase Chain Reaction (PCR) has been modeled. A microliter sample is driven along the microchannel by a flow generated by means of electroosmotic micropumps, activated in sequence. Several multichannel pumps configurations have been separately ... Mehr lesen
Uterine contractions during pregnancy are currently poorly understood – experts disagree on the mechanisms by which contractions propagate through the organ and the structural layout of the uterine muscle fibers. We have developed a multi-scale model of the uterus, at the cellular, ... Mehr lesen
The subject of the interactions between electromagnetic (EM) fields and living cells is a strong issue for several decades [1]. Large number of works have been done to study the EM field penetration and inner induced currents in living microorganisms. Relevant information to be collected ... Mehr lesen
The performance of a homogeneous T-mixer can be enhanced significantly by the stimulation of secondary/ transverse flows in the microchannel. Various mixing mechanisms are reported for enhancing micromixing performance such as grooves at the channel bottom, heterogeneous charge patterns ... Mehr lesen
In 1901 Weiss proposed an equation predicting activation of nerve fibers by electrical stimulation, used in neuroscience and neuromodulation, which applies electric fields to modify nerve behavior in neurological disorders. Weiss’ equation is relative to geometry, electrode array, ... Mehr lesen
Energy performances and building energy quality can be achieved by high performance envelopes. In this paper the thermal performance of a naturally ventilated façade, applied to a traditional wall, widely used in existing buildings, was investigated by a transient simulation. A ... Mehr lesen
Flow channel design in a PEM fuel cell plays a critical role for uniformly distributing reactants to the reaction sites and effectively removing product water to prevent flooding. Simplistic design and uniform reactant distribution make parallel channels a potential candidate for ... Mehr lesen
The present work deals with a numerical investigation of resonating systems used for noise control applications. In literature one can find analytical models based on fluiddynamics concepts for evaluating losses occurring across the holes of the perforates. In the paper an acoustical ... Mehr lesen
COMSOL Multiphysics® coupled with Solidworks® is employed to design, simulate and fabricate cartridges for a materials printer to accomplish in-situ curing of UV curable ink patterns as they are printed on flexible media for printed electronic circuit manufacturing. The cartridges ... Mehr lesen
This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of ... Mehr lesen
