Damage modeling of CO2 injection well interfaces under coupled thermal, hydraulic and mechanical behavior

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper presents an investigation of CO2 injection well damage evolution considering different injection temperatures and the presence of a pre‐existing defect. The main outcome is that the accurate prediction of well leakage risk requires characteristics such as initial defects to be understood and represented in any modeling efforts. Abstract This

On new stability estimations in Ramachandran–Rao characterization

open access: yesLietuvos Matematikos Rinkinys, 2008
B. Ramachandran and C.R. Rao have proved that if X, X1, X2, . . ., Xn are i.i.d. random variables and if distributions of sample mean \bar X = \bar X(n) = (X1 + ··· + Xn)/n and monomial X are coincident at least at two points n = j1 and n = j2 such that ...

Cauchy representation of distributions and applications to probability [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1990
The Cauchy representation is not valid for every Schwartz distribution f ∈ (D(R))′ because (t – x)−l ∉ D(R). Since for all z ∈ {z: Im z ≠ 0} the kernel (t – z)−l belongs to (R) (1 > p > ∞), the Cauchy representation of the distributions in ((R))′ seems possible.In this paper, we prove this fact.

Study on fracture parameter calibration and failure characteristics of rock with hole and crack

open access: yesDeep Underground Science and Engineering, EarlyView.
The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

Another Characteristic Property of the Cauchy Distribution [PDF]

open access: yesThe Annals of Mathematical Statistics, 1966
1. Main result. The purpose of this paper is to prove the theorem and corollary stated in this section. The corollary answers the question raised in Section 3 of [4] to which we also refer the reader for further motivation. THEOREM. Let X be a symmetric r.v., and Xi, i = 1, 2, , r.v.'s independently and identically distributed as X. The two conditions:

eBEfree: Combining Psychoeducation, Mindfulness, and Self‐Compassion in an App‐Based Psychological Intervention to Manage Binge‐Eating Symptoms: A Randomized Controlled Trial

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective To develop and test the effectiveness of the eBEfree program, a 12‐session app‐based version of a previously tested psychological intervention (BEfree) that combines psycho‐education, self‐compassion, mindfulness, and Acceptance and Commitment Therapy to reduce binge‐eating symptoms.

Stochastic Programming with Cauchy Distribution

open access: yesPakistan Journal of Statistics and Operation Research, 2015
The aim of this paper is to derive a method for solving a stochastic linear programming problem with Cauchy distribution. Assuming that the coefficients are distributed as Cauchy random variables, the stochastic linear programming is converted to a deterministic non-linear programming problem by a suitable transformation.

Electrochemical, Corrosion, and Dye Absorption Properties of Hydrothermally Grown 1D Nanostructured ZnO:Al Photoanodes

open access: yesEnergy Technology, EarlyView.
ZnO:Al (AZO) nanorods were grown using hexamethylenetetramine–hexamethylenediamine ligand mixture. AZO nanorods that can absorb visible rays, gained high light collection ability. Hexamethylenetetramine–hexamethylenediamine mixture caused the charge transitions at the electrode–electrolyte interface to accelerate and recombinations to decrease ...
