Guided wave technology offers a promising approach for non-destructive testing (NDT), particularly in the detection of corrosion in critical structures such as pipelines. This study focuses on utilizing COMSOL Multiphysics to simulate guided wave propagation for optimizing corrosion ... En savoir plus
Automotive battery development requires continuous improvements to be more time- and cost-efficient. Limited availability of prototype cells at various stages of design or of differing chemistry, age and health is a major challenge. A highly integrated model-based developing process can ...

The integrity and safety of reinforced concrete structures are of paramount importance in civil engineering. Detection of flaws in prestressed tendons, especially those buried at critical depths greater than 20 cm, presents a significant challenge. Magnetic flux leakage (MFL) is a non ... En savoir plus
Acoustic emissions generated by active defects in structures, like bridges, aircraft, and pipelines, play a crucial role in detecting flaws in their structural integrity by non-destructive evaluation techniques. Commercially used acoustic emission (AE) sensors are made of piezoelectric ... En savoir plus
Optical wave interference can perform instantaneous operations, such as: addition, subtraction, multiplication, and more complex operations like Fourier transform [1]. Being able to develop an optical computer that directly executes these operations without the need for a digital ... En savoir plus
As water networks around the world age, leakage and water main breaks are becoming an increasing problem. Leakage rates of 10-30% are typical in North America, and most cities suffer from hundreds (or thousands) of water main breaks every year. Echologics has developed the EchoShore ... En savoir plus
In this work, we demonstrate the implementation of the micromagnetic equations for the description of ferromagnetic thin films in COMSOL Multiphysics®. We apply our model to magnetoresistive sensors consisting of several soft ferromagnetic layers and their response to magnetic particles. ... En savoir plus
Ultrasound transducers are regularly used in medical clinics but their performance is known to deteriorate over time. Causes of this image quality degradation can include delamination between layers, physical breakage of components, short circuits and weakening crystals. Regular ... En savoir plus
A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing ... En savoir plus
A poly(methyl methacrylate) (PMMA) microfluidic platform with a hot-embossed microchannel, 150 mm wide and 20 mm deep, was developed for multiple purpose detection using electrochemical methods. This device is able to accommodate a three-electrode system encased in 1/16" diameter PEEK ... En savoir plus
