Impedance localization and identification

2020
The beam coupling impedance represents one of the sources of potential beam instabilities in particle accelerators. The localization of large coupling impedance sources is therefore very important in order to focus the efforts for mitigation measures when these are needed.

Contact impedance adaptation via environment identification

2008 IEEE International Symposium on Industrial Electronics, 2008
In this paper we present the results of an approach for identifying the environment using Bayesian inference methods. Using this information, the contact properties between a robotic manipulator and a particular scenario are regulated by means of an impedance controller that adapts to the identified environment. Off-line, the robot records sensory data

Fast summation transformation for battery impedance identification

2009 IEEE Aerospace conference, 2009
A battery is an important subsystem for electrical energy storage in many military, space and commercial applications. Consequently, in-situ diagnostics for state-of-health estimation of the battery is also critical for enhancing the overall applications' reliability.

Nonsmooth impedance profile identification using reflection data

The Journal of the Acoustical Society of America, 1997
Many works published about identification of acoustic properties of inhomogeneous media present methods based on the assumption that these properties vary smoothly along the propagation direction. This work presents a comparison between two time-domain sequential inverse methods for evaluation of either smooth or nonsmooth impedance profiles of ...

Impedance-Based Method for Nondestructive Damage Identification

Journal of Engineering Mechanics, 2005
A structural damage identification technique based on the impedance method is presented in this paper using smart piezoelectric transducer (PZT) patches. A modeling framework is developed to determine the structural impedance response and the dynamic output forces of PZT patches from the electric admittance measurements.

Experimental crack identification using electrical impedance tomography

NDT & E International, 2002
Abstract This paper addresses the problem of practical crack identification in electrically conducting specimens using only boundary measurements. The method is commonly referred to in the literature as Electrical Impedance Tomography (EIT). Crack identification is determined from the electrical impedance distribution, which amounts to solving an ...

Transmission Line Identification via Impedance Inhomogeneity Pattern

IEEE Journal of Radio Frequency Identification, 2019
This paper reports a new physical unclonable function (PUF) technology, namely, transmission line (TX-Line) PUF. We experimentally showed that using the intrinsic impedance inhomogeneity pattern, variation of characteristic impedance over distance, of any TX-Line, one can identify the TX-Line with high verification accuracy. The TX-Line PUF information

Electromechanical Impedance Based Part Identification via Linear Projection

ASME 2023 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2023
Abstract The geographical separation between various supply chain participants creates challenges in ensuring the integrity of the parts under circulation. These supply chains have to regularly deal with counterfeiting, a significant problem with an estimated value equivalent to at least the tenth-largest global economy.

Identification of soil properties from foundation impedance functions

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1992
This study evaluates the possibility of using experimentally determined foundation impedance functions to infer the dynamic properties of the underlying soil deposit. It evaluates a previously proposed method to identify soil properties from results of forced vibration tests of foundations.
