soil hydraulic properties are key soil physical characteristics that are required to conduct soil and water related studies such as irrigation and drainage. in this study, three indirect methods: inverse modeling, pedo-transfer function, and the semi-physical method of arya et al., were compared in a sandy loam soil to estimate soil moisture retention and unsaturated hydraulic conductivity curv...

In this paper a method for reliability analysis of restorable items is considered. We present the model describing a variation of reliability characteristics of objects and taking into account incomplete repair of operability after failure. The asymptotic solution for the intensity of the geometric process model is obtained. Reliability characteristics of the geometric process model for various...
