Large-scale manufacturing of electronic components require efficient forms of quality testing to ensure bulk fabrication and processing is performed to standard. With numerical simulations, the ideal behavior of such components may be evaluated to better know what to expect. ... En savoir plus
Electrochemical Impedance Spectroscopy (EIS) is a technique commonly used to investigate the properties of the electrode surface and the bulk electrolyte in an electrochemical cell [1]. An AC excitation signal is applied with a frequency range, typically from 0.01 Hz to 1 MHz, and the ... En savoir plus
The impedance tube is commonly used to characterize sound absorbing material. In order to obtain reliable results, the sample must fit perfectly into the cross section of the tube. In practice, this often results in a minimal gap between the sample and the wall of the tube. A narrow gap ... En savoir plus
The aim of this work is to investigate the impact of the structural parameter on the signal of the impedance based microfluidic flow cytometer for cell detection. A well-established optical technique for counting, identifying and sorting cells is flow cyto-fluorimetry, which is an ... En savoir plus
Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as ...

In the medium voltage distribution network, voltage transformers play unique and critical role to monitor the power line voltage and thus controlling the flow and distribution of the electrical energy in the grid. During their service time, the voltage transformers are relatively often ... En savoir plus
Nerve localization is important for applications in regional anesthesia. Localization is achieved by stimulating the nerve with an electric field produced by a current from a needle inserted into the body of the patient, close to the target nerve. Modeling of the electric field in close ... En savoir plus
Impedance spectroscopy is a measurement technique that has been investigated in a wide variety of medical applications. An example is the measurement of the dielectric properties of the skin and underlying tissue using sensors placed in contact with human skin with capacitive fringing ... En savoir plus
Quiet zones and other sound zones have been a strong topic of research for some time, due to the interest of creating separate sound environments in a same room, in a large open-space office for example. A number of solutions have been proposed over the last years. This paper further ... En savoir plus
This article reports the design of a high-power ultrasound system, capable of emitting acoustic radiation at 20kHz with SPL peaks up to 160dB at a distance of up to 1m. The main problem of high power airborne ultrasonic systems lies in the acoustic impedance mismatch between the radiator ... En savoir plus
