Modern electronic assemblies and printed circuit boards (PCB) with their sensitive structures and elements have to be protected against environmental influences by conformal coating or casting compounds. In this case the main challenge is the simultaneous curing of the polymers and the safekeeping of the electronic elements and structures on the PCB. This implies the investigation of the heating ...

Heating or cooling of stored fluids by thermal energy exchange with the enclosing walls may be enhanced by improving the efficiency of energy transfer; energy loss to the ambient is equalized for all simulations. Buoyancy driven internal natural convective flow is assumed to be the main energy transfer mechanism. In Newtonian fluids dynamic behaviour is described by the Navier-Stokes ...
Modeling Arterial Drug Transport From Drug-eluting Stents: Effect of Blood Flow on the Concentration Distribution Close to the Endothelial Surface

Drug-eluting stents (DES) are commonly used for treating coronary atherosclerosis. Despite the broad effectiveness of DES, ~5% of treated patients experience complications including in-stent restenosis and late-stent thrombosis. Furthermore, drugs used in DES not only inhibit proliferation of smooth muscle cells but also affect re-endothelialization. We have developed a computational model ...

Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have operation with gas pressure as low as possible (0.3 Pa). A multiphysics model of some major processes is here ...

Within the field of hot metal bulk forming the demand arises for fully three-dimensionally tailored properties at the microstructural level, nevertheless, reaching a predefined geometry with such tailored properties puts high requirements on the control mechanisms utilized in the process chain for combined heating, metal forming, and cooling processes. A simulation based rapid control ...

There is urgent need to monitor dental and oral diseases, such as tooth decay, gum diseases, and teeth grinding. Such monitoring can be achieved by embedding sensors in the mouth. This technique faces some difficulties. The first is how the power needed for the operation of the sensors and the associated electronic chips can be generated. This power can be generated using the pressure exerted by ...

Pitting corrosion is a complex phenomenon where rates of: i) chemical reactions, ii) diffusion of various species involve in those reactions, and iii) species dissolution at the metal-electrolyte interface are fully dependent on each other, except under special conditions or assumptions. One set of such conditions is that: a) there are no species concentration gradients due to the rapid mixing ...
