Study on corrosion resistance of AlCuxNiTiZr multi-principal element alloy films in NaCl solution

open access: yesAIP Advances, 2022
The corrosion resistance of multi-principal element alloy (MPEA) films is complex dependent on their composition. The purpose of this paper is to explain the relationship between the corrosion resistance and the Cu content of AlCuxNiTiZr MPEA films ...

Twin Shear Unified Strength Solution of Shale Gas Reservoir Collapse Deformation in the Process of Shale Gas Exploitation

open access: yesEnergies, 2022
The collapse deformation of shale has a significant influence on the exploitation process. Experimental analysis has indicated a correlation coefficient range from 0.9814 to 0.9981 and the established sample regression formula could be used to express ...

Rehabilitation of rail track facing cross-level issues using polymeric geocell [PDF]

open access: yesE3S Web of Conferences
One of the issues with the existing rail network is the cross-level issue, where the two parallel tracks have unwanted elevation differences, risking train derailment.

Conjugacy and principal solution of generalized half-linear second order differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
We study the generalized half-linear second order differential equation and the associated Riccati type differential equation. We introduce the concepts of minimal and principal solutions of these equations and using these concepts we prove a new ...

National Hockey League guaranteed contracts: A principal agent problem impacting on performance [PDF]

open access: yes, 2015
Purpose – This paper aims to investigate, through the lens of the principal–agent problem, the relationship between payment of National Hockey League (NHL) salaries and player performance during the period of 2005-2011 and explore the inherent issues ...

Solutions to the T-Systems with Principal Coefficients [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2016
The $A_\infty$ T-system, also called the octahedron recurrence, is a dynamical recurrence relation. It can be realized as mutation in a coefficient-free cluster algebra (Kedem 2008, Di Francesco and Kedem 2009). We define T-systems with principal coefficients from cluster algebra aspect, and give combinatorial solutions with respect to any valid ...

Mechanism design by an informed principal: the quasi-linear private-values case [PDF]

open access: yes, 2012
We show that, in environments with independent private values and transferable utility, a privately informed principal can solve her mechanism selection problem by implementing an allocation that is ex-ante optimal for her.

Spectral Discrimination of Macronutrient Deficiencies in Greenhouse Grown Flue-Cured Tobacco

open access: yesPlants, 2023
Remote sensing of nutrient disorders has become more common in recent years. Most research has considered one or two nutrient disorders and few studies have sought to distinguish among multiple macronutrient deficiencies.

Local estimates for modified Riccati equation in theory of half-linear differential equation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper we study the half-linear differential equation \begin{equation*} \bigl(r(t)\Phi_p(x')\bigr)'+c(t)\Phi_p(x)=0, \end{equation*} where $\Phi_p(x)=|x|^{p-2}x$, $p>1$. Using modified Riccati technique and suitable local estimates for terms
