43S Middle ear muscle reflex (MEMR) measurements have been a part of the standard clinical immittance test battery for decades as a cross-check with the behavioral audiogram and as a way to separate cochlear from retrocochlear pathologies. MEMR responses are measured in the ear canal by using a probe stimulus (e.g., single frequency or broadband noise) to monitor admittance changes elicited by ...

Introduction When analytically defining radio frequency circuits, a common approach incorporates admittance or impedance. Admittance, which is symbolized by Y, is defined in terms of conductance G and an imaginary susceptance component, jB. Admittance is often useful when defining parallel elements in a network and is expressed by the complex algebraic equation Y = G + jB. Impedance, the mathem...

Further integration of distributed renewable energy sources in distribution systems requires a paradigm change in grid management by the distribution system operators (DSO). DSOs are currently moving to an operational planning approach based on activating flexibility from distributed energy resources in day/hour-ahead stages. This paper follows the DSO trends by proposing a methodology for acti...

This paper describes electrical equivalent circuit models of cell–capillary admittance during injection of a living cell and presents a measurement system to estimate corresponding frequency responses during microinjection tests. Since the admittance estimate is calculated from data collected during injection, the amount of data is limited. To overcome this constraint, the approach proposed in ...

The analysis of DAR IMPATT diodes has been realized on basis of the precise drift-diffusion nonlinear model. The admittance characteristics of the DAR diode were analyzed in very wide frequency band from 30 up to 360 GHz. The energy characteristics have been optimized for the second high frequency band near the 220 GHz.

We present a current and charge conserving theory for the low frequency admittance of a quantum point contact. We derive expressions for the electrochemical capacitance and the displacement current. The latter is determined by the emittance which equals the ca-pacitance only in the limit of vanishing transmission. With the opening of channels the capacitance and the emittance decrease in a step...

We present a methodology for digital modeling ofD-dimensional driving-point bridge admittances from vibration measurements on instruments of the violin family. Our study, centered around the two-dimensional case for violin, viola, and cello, is based on using the modal framework to construct an admittance formulation providing physically meaningful and effective control over model parameters. I...

The analysis and optimization of the npvnp avalanche diode structure that includes two avalanche regions have been realized on basis of the nonlinear model and special optimization procedure. The admittance and energy characteristics of the DAR diode were analyzed in very wide frequency band from 30 up to 360 GHz. Output power level was optimized for the second frequency band near the 220 GHz.
