Slip-line field solution for ultimate bearing capacity of a pipeline on clayey soils [PDF]

, 2012
A slip-line field solution is presented for the ultimate bearing capacity of the pipeline on a purely-cohesive clay soil, taking into account the circular configuration of the pipe, the pipe embedment, and the pipe-soil interfacial cohesion.

Resolving discrepancies between laboratory-determined field capacity values and field water content observations: implications for irrigation management

Irrigation science, 2019
The concept of soil water contents at field capacity (FC at 0.33 MPa) and at wilting point (WP at 15 MPa) is often used to explain plant water availability and as maximal and minimal limits on observed soil water content. Field observations often differ,

MIMO Capacity in Binomial Field Networks

IEEE Access, 2017
We consider a multiple-input multiple-output (MIMO) communication in a binomial field of nodes scattered in a compact circular region. We first provide closed-form formulas for the Euler transform and Eulerian integral of H-function, which enable us to evaluate the integral in terms of again the H-function.
