Nonlinear descriptions of vertical earth pressure against positive buried pipelines based on minor principal stress trajectory

Yantu gongcheng xuebao, 2021
This study presents a nonlinear solution of vertical earth pressure against positive buried pipelines with three kinds of minor principal stress trajectories, such as the circular arc, the parabolic curve, and the rotation angle linearly changed.

Existence of a solution to the principal's problem [PDF]

Brazilian Review of Econometrics, 1987
This article deals with the existence of a solution to the Principal Agent Problem. Here we develops some basic results with the aid of Berge's Maximum Theorem. Also, a presentation of some interesting examples is given.

Principal solution of half-linear differential equation: Limit and integral characterization

Electronic Journal of Qualitative Theory of Differential Equations, 2008
We investigate integral and limit characterizations of the principal solution of the nonoscillatory half-linear differential equation $$ (r(t)\Phi(x'))'+c(t)\Phi(x)=0,\quad \Phi(x)=|x|^{p-2},\ p>1 $$.

Exact Solution Analysis of Strongly Convex Programming for Principal Component Pursuit

Information, 2017
In this paper, we address strongly convex programming for principal component analysis, which recovers a target matrix that is a superposition of low-complexity structures from a small set of linear measurements.

Practical solutions for complex variable function for radius of tunnel plastic zone under non-hydrostatic pressures and their application extension

Yantu gongcheng xuebao, 2023
In order to address the non-circular plastic boundary of rock circular tunnels under non-hydrostatic pressures, a simple complex variable function for the stress in an elastic zone is firstly introduced by using the analogy method.

Polyaxial strength criterion and closed-form solution for squeezing rock conditions

Journal of Rock Mechanics and Geotechnical Engineering, 2020
In this paper, a nonlinear strength criterion is proposed using the average of intermediate (σ2) and minor (σ3) principal stresses in place of σ3 in Ramamurthy (1994)'s strength criterion.
