The French National Waste Management Agency (Andra) envisages the safe disposal of High-Level Waste Intermediate-Level Long-Lived Waste through deep geological storage (multibarrier). Waste storage is based on the Callovo-Oxfordian formation (CallOx). It has been updated a reactive transport model accounting for the chemical and thermal evolution of a HLW cell. Improvements are a better ...

We are investigating gold-plated micromachined silicon integrating cavities for arrays of far infrared Transition Edge Sensor bolometers. We present the results of our simulations and show how we used COMSOL Multiphysics® software to optimize the geometry of the integrating cavity. We show that we can achieve a high optical efficiency over a wide frequency range.

The mathematical model is closely related to the development of a novel drying method for high viscous and sticky materials. The foamed state facilitates diffusive moisture transport and therefore accelerating the drying process. Moreover the dried porous material can be easily converted into the powder. The mathematical modelling aimed at evaluating the complex drying process as basic ...

Sensors have diverse applications ranging from medical field to space explorations. They convert physical parameters such as temperature, pressure, humidity etc: - into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of pressure sensors. Improvement in the sensitivity is the major factor to be considered while designing pressure ...

Medium- and high-voltage circuit breakers and reclosers are important grid protection devices that connect different grid sources and increase the network/grid reliability. Currently, there is a clear need of increasing the numbers of switching operation. Therefore, the optimal design of these devices becomes of extreme importance in order to enable the required switching capabilities. This ...

We calculate the maximum force acting on the mirror and found it to be 0.54 µN at 700 V. The force magnitude can be improved by increasing voltage and diminishing the separation between plates. The force along X, Y-axis acts towards the center of the plates and in Z direction towards the plates to which the mass is closer.

With the progress of immunosensing technology, the detection of diseases at early stages is feasible using surface based heterogeneous immunosensors . Literature contains few reports where it is verified that reaction spot of smaller size leads to high fractional occupancy of targets, specifically applicable to the microarray technology . Such enhancement in capture efficiency by the ...

A finite element model is employed to describe the electric potential distribution and electroosmotic flow field inside a wavy cylindrical channel. The model uses coupled Laplace and Poisson-Boltzmann to evaluate the electric potential distribution inside the channel. It also contains continuity and Navier–Stokes equations for the solution of fluid flow. A particle trajectory model was ...

Subduction processes have great importance as are related to volcanism and earthquake occurrence. Old and cold plates should subduct steeper than younger ones, but the subduction angle is highly variable and does not always correlate with the age of the plates. Some researchers propose a global or net westward drift of the lithosphere relative to the mantle and this assessment is still a matter ...

The problem is to understand how a geothermal field can evolve from a water dominated state into a vapor dominated one. A first answer to this question is given by a simplified mathematical model of the dynamics of a geothermal field in which the geothermal fluid is entirely composed by pure H2O. We considered a 1-D geometry and we developed a dynamic model that presents a clear interface ...
