ogs5py: A Python‐API for the OpenGeoSys 5 Scientific Modeling Package

Groundwater, Volume 59, Issue 1, Page 117-122, January/February 2021., 2021
Abstract High‐performance numerical codes are an indispensable tool for hydrogeologists when modeling subsurface flow and transport systems. But as they are written in compiled languages, like C/C++ or Fortran, established software packages are rarely user‐friendly, limiting a wider adoption of such tools.

Efficient Visualization Method and Implementation of Reservoir Model Based on WPF

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
In view of the slow speed and poor effect of real‐time rendering of large‐scale reservoir geological grid model, a new grid model hidden algorithm is proposed by analyzing the Eclipse reservoir grid model storage format, grid model representation, and cell sorting rule, which optimizes the original grid data and improves the rendering speed of ...

Crack identification for bridge condition monitoring using deep convolutional networks trained with a feedback-update strategy

Maintenance Reliability and Condition Monitoring, 2021
Orthotropic steel bridge decks and steel box girders are key structures of long-span bridges. Fatigue cracks often occur in these structures due to coupled factors of initial material flaws and dynamic vehicle loads, which drives the need for automating ...

Neutron diffraction measurements of weld residual stresses in three‐pass slot weld (Alloy 600/82) and assessment of the measurement uncertainty

Journal of Applied Crystallography, Volume 53, Issue 5, Page 1181-1194, October 2020., 2020
Residual strain measurements were conducted on an Alloy 600/82 weld on five diffractometers, and two different approaches were used to analyse the data and estimate the stresses. The large body of data enabled estimation of the Bayesian mean of the residual stress distribution and a statistically robust estimation of the residual stress uncertainty ...

Does Financial Development Hamper or Improve the Resource Curse? Analysis Based on the Panel Threshold Effect Model

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This paper analyzes the “resource curse” and “financial threshold effect” that may exist in China and then uses the data from 30 provinces from 2004 to 2018 as research samples. We used linear regression and nondynamic panel threshold models to analyze the financial threshold effects of the “resource curse” hypothesis and the “resource curse ...

Asymptotic symmetry and conservation laws in 2d Poincar\'e gauge theory of gravity

, 1996
The structure of the asymptotic symmetry in the Poincar\'e gauge theory of gravity in 2d is clarified by using the Hamiltonian formalism. The improved form of the generator of the asymptotic symmetry is found for very general asymptotic behaviour of ...

IDEALS AND FINITENESS CONDITIONS FOR SUBSEMIGROUPS [PDF]

Glasgow Mathematical Journal, 2013
AbstractIn this paper we consider a number of finiteness conditions for semigroups related to their ideal structure, and ask whether such conditions are preserved by sub- or supersemigroups with finite Rees or Green index. Specific properties under consideration include stability,$\mathcal{D}=\mathcal{J}$and minimal conditions on ideals.

Growth of maps, distortion in groups and symplectic geometry

, 2000
In the present paper we study two sequences of real numbers associated to a symplectic diffeomorphism: the uniform norm of the differential of its n-th iteration and the word length of its n-th iteration.

Arithmetical pluralism and the objectivity of syntax

Noûs, Volume 59, Issue 2, Page 372-391, June 2025.
Abstract Arithmetical pluralism is the view that there is not one true arithmetic but rather many apparently conflicting arithmetical theories, each true in its own language. While pluralism has recently attracted considerable interest, it has also faced significant criticism.
