The soil water retention curve (SWRC) is essential for assessing flow and solute transport in unsaturated media. van Genuchten (VG) model widely used to describe the SWRC; however, estimation of its effective hydraulic parameters often prone error, especially when data exist only a limited range matric potential. We developed Metropolis-Hastings algorithm Markov chain Monte Carlo (MH-MCMC) appr...

polarization for au/pb(zr ti )o /yba cu o ferroelectric capacitor has been studied and measured by pulse method. a sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. a value of 25?c/cm2 is measured for the saturated p...

Analysing unsaturated soil response often requires the soil-water-retention-curve (SWRC). The SWRC depends upon microstructure, which evolves with hydromechanical loading such as in-situ exposure to wetting-drying cycles. If is of interest and studied in laboratory, it essential specimens have a structure representative conditions. Simulating cycles laboratory possible albeit time-consuming fas...
