The technique is based on the principle that lean tissue has a higher electrical conductivity and a lower impedance rate than fat. 

Electric impedance tomography is a new imaging technique that is potentially capable of monitoring those imbalances. 

This was because the coupling resistance value had inverse effects on the amount of current arriving and on the impedance of the neurite. 

As the signal propagates down a path, the voltage magnitude is related to the effective impedance up to the point in the signal's flight.

Each antenna features vertical polarization, with an impedance of 50 ohms. 

Again, the agreement between the full wave and quasistatic calculations is due to the use of equations 4 and 5 to find the surface impedance of the lossy semiconductor layer. 

The functional significance of hemichannel activity in lens tissue has been ruled unlikely due to the apparent high impedance of lens fiber cell membranes. 

As I said, the impedance of a capacitor is inversely proportional to its capacitance and the impedance of an inductor directly proportional to its inductance.

The documentation or specifications for the particular electrometer being used will generally provide the value of its feedback impedance. 

This freeware version allows users to trend voltages, impedance, strap resistances, cell temperature and specific gravity. 

But the impedance mismatch between SQL and Java was no better than between SQL and other languages. 

Cell impedance was monitored over several weeks in culture, and the effect of nephrotoxin treatment on cell impedance was investigated. 

Some argue that having impedance mismatch is difficult for programming intensive applications. 

The main goal of PDN design is to minimize the impedance between power and ground, across a range of frequencies. 

In humans, the middle ear works as an impedance equalizer between the outside air's low impedance and the cochlear fluid's high impedance. 

This can be described by a variation in the electrical impedance of the coil, that is, its ohmic resistance and inductive reactance. 

It consists of voltage source from the rectifier supply, impedance network, three phase inverter and three phase load. 

Body mass and body composition were estimated using a multifrequency impedance plethysmograph body composition analyser. 

In its place we use impedance, Z, which is a measure of a circuit's tendency to resist the flow of an alternating electrical current. 

In humans, the middle ear works as an impedance equaliser between the outside air's low impedance and the cochlear fluid's high impedance. 

Dehydration is arguably the single most preventable impedance to running performance, while overhydrating remains a danger for runners all too aware of the first fact. 

They also lack the ability to measure absolute MW composite material properties such as permittivity, permeability, complex impedance and conductance. 

Heart rate and respiration was monitored through thoracic needle electrodes coupled to a higain coupler and an impedance pneumograph coupler, respectively.
