Water-and-energy supply is a global issue of paramount importance. The demand for safe potable water is quickly exceeding the limits of natural regional water resources. Like oil, water is a finite resource; unlike oil, however, water has no alternatives. Water, energy and their environmentally sound solutions are interrelated; and of all the present-day environmental problems, those related to ...

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, a new quasi-TEM capacitance and inductance analysis of multiconductor multilayer interconnects is successfully demonstrated using the finite element method (FEM) ...
COMSOL Multiphysics Modelling for Measurement Device of Electrical Resistivity in Laboratory Test Cell
C. Rémi, M. Bergeron, and S. Moreau
Bioreactor landfill is based on a homogeneous distribution of the moisture content to increase waste biodegradation. Most of studies have shown that Electrical Resistivity Tomography (ERT) can be a suitable method to study water content variation (2D and 3D). ERT is influenced by many physical parameters and no single relationship with volumetric water content was yet established for Municipal ...

In COMSOL Multiphysics it is possible to implement and simulate several independent models in parallel. This can be meaningful when the different models are coupled to each other by some kind of interaction. If a part of the geometries is identical in all models, this part can be reduced in that it is implemented in only one of the geometries. In the other geometries only its solution towards its ...
Quasi-static Analysis on the Effect of Metal Penetrating Depth into the Substrate in Microstriplines

The effect of metallization thickness on planar transmission lines plays an essential role in microwave integrated circuits and thin film technology, especially in the propagation characterization and the electric field distribution in the structures. The objective of this paper is to consider the planar transmission lines with finite thickness not penetrating and penetrating into isotropic ...

Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and form chains of particles within the matrix. These chains cause the MRE to change its stiffness properties when ...

The paper presents the results of the experiment consisting in determination of the influence of the magnetic field on deformations of the stator and the rotor of the DC motor. The numerical model of the motor for the frameless DC machine of the G series has been elaborated. Real material properties and the phenomenon of the magnetic circuit saturation have been taken into consideration. The ...

Flexible electronics are temporarily affixed to a rigid carrier such as glass or silicon prior to device fabrication to facilitate robotic handling of the device, but also to allow optical lithography to stay within overlay design registration budget; without the rigid carrier, a freestanding flexible substrate such as polyimide would distort unacceptably during even minor temperature excursions ...

The swelling behavior of human intervertebral disc is strongly influenced by chemical changes in the surrounding environment. Swelling of IVD is governed by various physical phenomena, including chemical and electric potential based transport, electrical charge balance, and swelling due to concentration difference within IVD relative to surrounding fluid. This change in geometry can be described ...

We propose the study of an electronic sensor allowing the collection of sprays in free space. The detector consists of three elements: a photodiode situated in the center of the structure to which is applied a bias voltage, an aluminum ring which referenced to a voltage higher than that of the photodiode and an insulating material disk (polyvinyl chloride). The total size of the structure is ...
