The evaluation of defect size and nature are two most controversial topics in ultrasonic flaw detection. The operation consists of an application of ultrasonic waves to pipes in order to detect metal loss and other defects in the pipe wall due to corrosion and other degradation ... En savoir plus
The paper presents the numerical analysis of quench propagation in a DH magnet wound with a commercially available MgB2 wire in a fiber-glass composite matrix and operating at 20 K. The quench is induced by a small heater located on the first layer of the magnet close to the peak field ... En savoir plus
In India, more than 150,000 people are killed each year in traffic accidents, according to the Ministry of Road Transport and Highways 2016 report. That’s about 400 fatalities a day, which is far higher than in developed auto markets like the US which, in 2016, logged about 40,000 a ... En savoir plus
We present simulated examples of analyzing characteristics of terahertz communication devices by using the COMSOL RF module. Especially, we propose a coupled analysis method, which has a mutually complementary relationship between the numerical analysis in the COMSOL and an additional ... 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
A 3D finite element model (FEM) of the PEMC sensor was developed to characterize the modes of vibration that have demonstrated high sensitivity to mass-change in experimentally fabricated sensors. The fundamental bending mode of vibration and the 1st bending harmonic are predicted at 10 ... En savoir plus
The location and nature of the moisture leakages are sometimes difficult to detect. Moreover, the relation between observed inside surface moisture patterns and where the moisture enters the construction is often not clear. The objective of this paper is to investigate inverse modeling ... En savoir plus
A high performance MEMS Pirani sensor (VAC_03) was designed and optimized based on analytics. Due to the fact that this MEMS Pirani sensor is a 3D-Object, the calculation of the thermal radiation by analytics is limited. As the radiation behavior in the system is, beside the solid ...

The novel Micro Electro Mechanical System (MEMS) based Piezoresistive stain sensor is presented in this paper. The main goal of this sensor is to monitor the localized strain in the highway bridges especially near the crack tips. Monitoring the crack growth on the bridges can lead to ... En savoir plus
We present time-resolved methods that rely on near-infrared photons to image the optical properties and distribution of fluorescent probes in small laboratory animals. The coupled diffusion equations of excitation and fluorescence photons in highly scattering tissues were solved using ... En savoir plus
