Inverse Heat Conduction

, 2023
This book discusses the engineering problem of determining surface heat flux and temperature history based on interior temperature measurements. It also provides the analytical techniques needed to arrive at otherwise difficult solutions, summarizing the

The structure of the potassium channel: molecular basis of K+ conduction and selectivity.

Science, 1998
The potassium channel from Streptomyces lividans is an integral membrane protein with sequence similarity to all known K+ channels, particularly in the pore region.

Conduction of Heat in Solids

, 1952
Materials engineers easily recognize that the conduction of heat within solids is fundamental to understanding and controlling many processes. We could cite numerous examples to emphasize the importance of this topic.

Capillary conduction of liquids through porous mediums

, 1931
The flow of liquids in unsaturated porous mediums follows the ordinary laws of hydrodynamics, the motion being produced by gravity and the pressure gradient force acting in the liquid.

Statistical-Mechanical Theory of Irreversible Processes : I. General Theory and Simple Applications to Magnetic and Conduction Problems

, 1957
A general type of fluctuation-dissipation theorem is discussed to show that the physical quantities such as complex susceptibility of magnetic or electric polarization and complex conductivity for electric conduction are rigorously expressed in terms of ...

Intrinsic conductivity of conducting polymers

Synthetic Metals, 1988
Because the charged dopant ions are spatially separated from the quasi-one-dimensional conduction path in conducting polymers, resistive back scattering is suppressed. In the case of high molecular weight and relatively few sp3 defects, even relatively weak interchain coupling is sufficient to avoid one-dimensional localization; this leads to coherent ...

Conductivity and photoconductivity of conducting polymers

Physica Scripta, 1992
A review is presented of the state of the art of conducting polymers. Special attention is given to the high electrical conductivity of highly ordered doped polyacetylene, to the attempts to reproduce σ-values above 105 S/cm, and to efforts to correlate the electrical conductivity with other physical parameters (European Brite/Euram Project HICOPOL).

Percolation and Conduction

, 1973
Extensions of percolation theory to treat transport are described. Resistor networks, from which resistors are removed at random, provide the natural generalization of the lattice models for which percolation thresholds and percolation probabilities have
