A Time-Domain Reflectometry Method with Variable Needle Pulse Width for Measuring the Dielectric Properties of Materials

open access: yesSensors, 2016
Time-domain reflectometry (TDR) methods used for measuring the dielectric properties of materials mostly utilize step or needle electrical pulses of constant amplitudes and shapes.

The new integral relaxation time for thermal activation of spins

open access: yes, 1999
The integral relaxation time for the difference of populations of the two potential wells for double-well classical spin systems is introduced. For the uniaxial symmetry, it is given by a quadrature.

Continuous-time relaxation labeling processes

open access: yesPattern Recognition, 1999
Abstract We study the dynamical properties of two new relaxation labeling schemes described in terms of differential equations, and hence evolving in continuous time. This contrasts with the customary approach to defining relaxation labeling algorithms which prefers discrete time.

Stretched exponential relaxation in the Coulomb glass

open access: yes, 2001
The relaxation of the specific heat and the entropy to their equilibrium values is investigated numerically for the three-dimensional Coulomb glass at very low temperatures. The long time relaxation follows a stretched exponential function, $f(t)=f_0\exp[

Thermomagnetic effect on the propagation of Rayleigh waves in an isotropic homogeneous elastic half-space under initial stress

open access: yesCogent Engineering, 2015
Rayleigh wave propagation in an isotropic homogeneous initially stressed thermoelastic half-space under the effect of magnetic field has been studied using Green–Lindsay (GL) theory of generalized thermoelasticity.

Characterization of Piezoresistive PEDOT:PSS Pressure Sensors with Inter-Digitated and Cross-Point Electrode Structures

open access: yesSensors, 2015
The piezoresistive characteristics of poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) pressure sensors with inter-digitated (IDE) and cross-point electrode (CPE) structures have been investigated. A small variation of the resistance of

Relaxation patterns and semi-Markov dynamics

open access: yes, 2018
Exponential relaxation to equilibrium is a typical property of physical systems, but inhomogeneities are known to distort the exponential relaxation curve, leading to a wide variety of relaxation patterns.

Relaxation Processes in Clouds of Trapped Bosons above the Bose-Einstein Condensation Temperature

open access: yes, 1998
We present a unified account of damping of low-lying collective modes and of relaxation of temperature anisotropies in a trapped Bose gas in the collisionless regime.

Relax-Time

open access: yes, 2010
La idea de nuestro negocio consiste principalmente en ofrecer un lugar de relajación, el cual cuenta con hamacas, zona de video juegos, zona de masajes y mascarillas hidratantes. Este lugar sería cerca a las universidades Icesi, San Buenaventura, Javeriana, Católica, Autónoma y San Martín, con el fin, de que en los espacios de tiempo donde no hay clase,
