Non-destructive Evaluation (NDE) techniques are widely used for early detection of defects in engineering components without impairing their future usefulness. Among them, Eddy Current (EC) technique is used for detection of defects in electrically conducting materials and it is known ... En savoir plus
Today, 90 percent of automation sensors are binary proximity detectors. Besides capacitive and optical types, inductive proximity sensors are essential for industrial applications. Compared to their mechanical counterparts, they offer almost ideal properties as contact-free and wear-free ... En savoir plus
Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such ... En savoir plus
Temperature changes in the body have been recognized as an indicator of illness for centuries and localized temperature variations due to inflammatory or ischemic events are common in a great variety of diseases. In the case of cancerous breast tumors the increased cell growth rate ... En savoir plus
A COMSOL model of a piezoelectric quartz double ended tuning fork gyroscope was implemented. The gyroscope has two detection modes; the first mode detects the angular velocity about a z-axis perpendicular to the tuning fork plane (x-y plane), while the second mode detects the angular ...

Breast cancer detection is one of the most important problems in health care and it is second most frequent cancer according to WHO. It is recommended that women over fifty or even younger in some cases do a screening test every two years. Besides clinical breast examination, there are ... En savoir plus
Two transmitting planar microcoils (TX1, TX2) and one receiving microcoil (RX) are employed as shown in Fig.1 formed in induction-balance configuration. RX-Coil is positioned in such a way to achieve primary field suppression in RX-Coil’s region. Meaning, a magnetic cavity is created in ... En savoir plus
Ultrasonic Testing (UT) is one of the important Non-Destructive Evaluation (NDE) technique widely used for characterisation of materials as well as detection and characterisation of flaws present in the material used in various industries. There are many different important materials ... En savoir plus
It is known that photoacoustic spectroscopy shows the highest signal-to-noise ratio compared to other spectroscopy techniques. This is due to an orthogonal detection scheme: while exciting with light we monitor soundwaves. In gaseous phase, the use of an acoustic chamber called cell ... En savoir plus
Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We ... En savoir plus
