Volume Conduction Influences Scalp-Based Connectivity Estimates

Volume conduction energy transfer for implantable devices

A common model of power supply for implantable devices was established to study factors affecting volume conduction energy transfer. Electromagnetic and equivalent circuit models were constructed to study the effect of separation between the source electrode pairs on volume conduction energy transfer. In addition, the parameters of external signal including waveform, amplitude and frequency wer...

Volume expansion of nonmyelinated nerve fibers during impulse conduction.

Nonmyelinated nerve fibers undergo rapid volume expansion while carrying an impulse. This volume expansion is incurred as a consequence of a lateral expansion of the excited portion of the fibers, where the superficial layer is transformed into a low-density structure.

Solving Transient Conduction and Radiation Using Finite Volume Method

Radiative heat transfer in participating medium has been carried out using the finite volume method. The radiative transfer equations are formulated for absorbing and anisotropically scattering and emitting medium. The solution strategy is discussed and the conditions for computational stability are conferred. The equations have been solved for transient radiative medium and transient radiation...

The influence of fetoabdominal volume conduction on the fetal MCG

Fetal magnetocardiograms (MCG) can be measured non-invasively. From these measurements the duration of the various waves in the fetal cardiogram can be obtained as well as the fetal heart rate. Hence, the fetal MCG can, for instance, be used to classify arrhythmias. However, the amplitudes within the measured cardiogram depend on the fetoabdominal anatomy. For instance, the position of the meas...
