Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimise power consumptions of building. One technological approach is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 μm. Key features for a wider use in public and private buildings are power consumption and price. Such optical ...

Given any equation L(u)=0, e.g. a partial differential equation, it can be considered to be the stationary solution of a time dependent equation (in fact, time need only to be fictitious time not real time). Our approach is to choose the time dependence in analogy with an oscillating particle system including damping in order to damp out the time derivatives and attain a stationary solution ...

The two wooden cabinets of Jan van Mekeren that are located in Amerongen Castle show comparable wood damage; in particular large cracks in the cabinet doors are clearly noticeable. It is assumed that these cracks were caused by bad indoor climate conditions in the castle. Combined computational modelling of the indoor climate conditions in the castle and the hygroscopic and mechanical ...

In this paper we present an analysis that shows the Maxwell Fish Eye (MFE) only has super-resolution property for some particular frequencies (for other frequencies, the MFE behaves as conventional imaging lens). These frequencies are directly connected with the Schumann resonance frequencies of spherical symmetric systems. The analysis have been done using a thin spherical waveguide (two ...

An electromagnetic horn is a device used in particle physics to produce a strong pulsed toroidal magnetic field and to focus charged particles toward a detector. A multiphysics analysis is performed to assess the stress level inside the horn structure. In steady state regime, the horn is submitted to a thermal static stress due to thermal dilatation. Then, every 80 ms a strong magnetic field ...
The developments of microsystems for biotechnology have been fast in the last few years, and no sign of slowing down is observed. It has begun with lab-on-chip for genomics, especially for the recognition of DNA sequences, followed by protein reactors and immunoassays, and today the emphasis is on cellomics. Cell-chips are design to monitor the behavior of cells, individually or as a group, ...

In this article we present Simulations results of an evaporation reactor for optical layer applications. The thermal simulation concern the source of the evaporated material. An experimental problem is ralated to the shape of the material powder surface: due to the evaporation rate, the surface don\'t keep his flat initial shape and this has a strong effect on the local evaporation rate. In ...

We consider a 3D boundary value problem arising in electrostatics. The potential is stimulated by current sources placed on a cross-section S of the domain. In many applications it is sufficient to know the potential in S. So, one is interested in an appropriate 2D model taking into account that the solution depends on the dimension of the domain. The idea is to find a corresponding 2D ...

The High Flux Isotope Reactor, located at the Oak Ridge National Laboratory, is scheduled to undergo a conversion of the fuel used and this proposed change requires an extensive analysis of the flow through the reactor core. The core consists of approximately 500 very thin and long fuel plates through which the coolant (water) flows at a very high rate. Therefore, the design and the flow ...
