Model Predictive Impedance Control: A Model for Joint Movement
Journal of Motor Behavior, 1997Impedance control has been suggested as the strategy employed by the central nervous system to control human postures and movements. A realization of this strategy is presented that uses a model predictive control algorithm as a higher motor controller. External disturbances are explicitly included in the model.

Models for representing the acoustic radiation impedance of the mouth
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1985The acoustic radiation impedance of the mouth is important in the production of speech in that it affects the amount of acoustic power radiated away from the mouth and it influences the acoustic response of the excited vocal tract. Five existing methods of modeling the acoustic radiation impedance of the mouth are: 1) the pulsating sphere, 2) the ...

Cole Electrical Impedance Model—A Critique and an Alternative
IEEE Transactions on Biomedical Engineering, 2005The Cole single-dispersion impedance model is based upon a constant phase element (CPE), a conductance parameter as a dependent parameter and a characteristic time constant as an independent parameter. Usually however, the time constant of tissue or cell suspensions is conductance dependent, and so the Cole model is incompatible with general relaxation

A model for precise identification of reflections in mixed distributed-lumped high frequency structures is proposed. The adequate structure that is suitable for this model class is a cascade of transmission lines tapped by lumped elements which are the source of the reflections.

Although the perfectly conducting ground model is adequate for many applications, it is not universally applicable. A more accurate model is required for surface wave propagation, for correct modelling of reflection effects at vertical polarization or for the modelling of propagation over rough surfaces.

The Impedance Mismatch in Light of the Unified State Model
Fundamenta Informaticae, 2012In this paper we discuss the misunderstanding that have arisen over the years around the broadly defined term of the object-relational impedance mismatch. It occurs in various aspects of database application programming. There are three concerns judged the most important: mismatching data models, mismatching binding times and mismatching object ...

Simplified Impedance Model for Adhesively Bonded Piezo-Impedance Transducers
Journal of Aerospace Engineering, 2009The electromechanical impedance technique employs surface-bonded lead zirconate titanate piezoelectric ceramic patches as impedance transducers for structural health monitoring and nondestructive evaluation. The patches are bonded to the monitored structures using finitely thick adhesive bond layer, which introduces shear lag effect, thus invariably ...

Analytical Chemistry
Localized electrochemical impedance spectroscopy (LEIS) is a powerful technique for probing complex electrochemical processes and demonstrates significant potential for practical applications. The nanopipette-based LEIS method offers enhanced spatial resolution, establishing it as a promising new approach in impedance spectroscopy.

The validity of the linear orifice impedance model for predicting the impedance of a tube
The Journal of the Acoustical Society of America, 1992The orifice impedance model usually works well for modeling sound transmission through an orifice. However, for a long orifice or for an orifice with a large load impedance, the standard impedance model may be invalid. The goal of this paper is to establish when the orifice impedance model gives a valid estimate of the impedance of a tube in series ...
