Nonlinear Conductivity in Dicyanoquinonediimine Complexes

Journal of the Physical Society of Japan, 2010
Nonlinear conductivity is observed below the metal–insulator (M–I) transitions of molecular conductors, halogen-substituted ( R 1 , R 2 -DCNQI) 2 Cu (DCNQI: dicyanoquinonediimine, R 1 , R 2 : methyl or halogen). Despite the difference of the M–I transition temperatures depending on the halogens, these compounds show nonlinear properties at similar low ...

Nonlinear Optimal Control Problems in Heat Conduction

SIAM Journal on Control and Optimization, 1983
The authors solve two nonlinear problems of optimal control. The first concerns the Stefan problem for temperature u(x,t) and moving boundary \(h(t)>0:\) Let \(T>0\) fixed, maximize h(T) subject to \(u_ t-u_{xx}=0\), \(u(x,0)=\phi(x)\), \(-u_ x(0,t)=g(t)\), \(u(h(t),t)\), \(h(0)=b>0\), where b, \(\phi\) are given and the control g is a nonnegative ...

Nonlinear Conductivity Fluctuations in Fe-Chalcogenide Superconductors

IEEE Transactions on Applied Superconductivity, 2013
Electric transport and voltage-noise measurements on FeTe0.5Se0.5 epitaxial thin films are reported. The films were grown by pulsed laser ablation deposition on lanthanum aluminate single crystal substrates, and subsequently patterned by ion beam etching. Several configurations, with different voltage contacts distances and different strip widths, have

A novel nonlinear regression model of SVR as a substitute for ANN to predict conductivity of MWCNT-CuO/water hybrid nanofluid based on empirical data

Physica A: Statistical Mechanics and its Applications, 2019
An ideal regression method should have several characteristics including precision, accuracy and generalization. In many studies in the field of nanofluid, the precision of models is more highlighted.

A Cauchy problem in nonlinear heat conduction

Journal of Physics A: Mathematical and General, 2006
A Cauchy problem on the semiline for a nonlinear diffusion equation is considered, with a boundary condition corresponding to a prescribed thermal conductivity at the origin. The problem is mapped into a moving boundary problem for the linear heat equation with a Robin-type boundary condition.

One-dimensional nonlinear inverse heat conduction technique

Numerical Heat Transfer, Part B: Fundamentals, 1986
The one-dimensional nonlinear problem of heat conduction is considered. A noniterative space-marching finite-difference algorithm is developed to estimate the surface temperature and heat flux from temperature measurements at subsurface locations. The trade-off between resolution and variance of the estimates of the surface conditions is discussed ...

Nonlinear Pricing as Exclusionary Conduct [PDF]

, 2012
We study the exclusionary properties of nonlinear pricing by dominant firms in a static environment. Optimal price schedules are nonlinear when the rivals’ sensitivity to competitive pressure varies with the “contestable share” of the market. When buyers can dispose of unconsumed units at no cost, and thus might purchase units they do not need ...
