Abstract Both EPR and nuclear frequency spectra are most easily interpreted in the high-field limit where the electron or nuclear Zeeman interaction are the dominating interactions in the relevant spin Hamiltonian. On the other hand some pulse EPR experiments such as nuclear modulation techniques can only be applied if field-independent ...

MULTI-FREQUENCY ICE DETECTION SYSTEM
Sensors and Microsystems, 2008This paper presents the design and performance evaluation of a new sensor system for detecting the presence of water or ice films on its surface. The system is based on a multifrequency capacitive measurement and the effect that water and ice have different dielectric constants.

Multi-frequency transformation for edge detection
Proceedings of the 27th Conference on Image and Vision Computing New Zealand, 2012This paper investigates the use of a multi-frequency transformation for edge detection. Most edge detectors are good at detecting non-texture edges, but have problems with texture edges. In order to detect texture edges, prior knowledge is usually required to avoid heavy computational cost. In this study, a fast and simple transformation based on multi-

Systematic errors in multi-frequency EIT
Physiological Measurement, 2000Systematic errors have been measured with a multi-frequency data-collection system operating between 10.24 and 81.92 kHz. The errors were present even though a conventional background measurement on a uniform saline phantom had already been subtracted.

A multi-frequency method for ultrasonic ranging
Ultrasonics, 2015This paper presents a method for ultrasonic ranging based on the cross-correlation of two multi-frequency signals. The stimulus signal is composed by multiple sine-wave bursts/segments, each containing a different frequency and an integer number of periods.

Multi-frequency transmission tomography
The Journal of the Acoustical Society of America, 1983Multi-frequency signals were transmitted using a plane-wave transducer, through a water immersed phantom consisting of two finger cots, one containing 50% isopropanol alcohol and the other containing normal saline. The scattered ultrasound was received with a small hydrophone and detected with a quadrature detection system.
