Generalized Iterative Methods for Solving Double Saddle Point Problem

پژوهش‌های ریاضی, 2019
In this paper, we develop some stationary iterative schemes in block forms for solving double saddle point problem. To this end, we first generalize the Jacobi iterative method and study its convergence under certain condition.

Carbonate microfacies and transgressive‐regressive sequences of Oxfordian shallow‐water limestones (Korallenoolith, Lower Saxony Basin)

The Depositional Record, EarlyView.
The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

Failure Law of Soft and Hard Interlayer Overlying Rock in Gently Inclined, Super‐Thick Coal Seam and Research on the Development Height of a Water‐Conducting Fissure Zone

Energy Science &Engineering, EarlyView.
Based on the layered structural characteristics of the strata, this study summarizes four typical overburden structural types under the geological conditions of the 51408 working face. Through theoretical derivation and numerical simulation, the study reveals the stepwise failure characteristics of the overburden and analyzes the variations in ...

A path to reconciliation between Indigenous and settler–colonial epistemologies

Frontiers in Ecology and the Environment, EarlyView.
There is a movement across settler–colonial institutions of education and research to engage with Indigenous Peoples and Knowledges. Many settler and Indigenous governments are pursuing pathways to move forward together to address global problems such as climate change. However, given the pervasive history of exploitation and displacement of Indigenous

Comparison of Numerical Methods for Geometric Warpage Compensation

International Journal for Numerical Methods in Fluids, EarlyView.
In the process of injection molding, shrinkage and warpage can lead to variations in the size and shape of produced parts compared to the cavity shape. Our research evaluated different algorithms for warpage compensation in injection molding. Our main finding was that the reverse geometry method consistently outperformed other tested algorithms on all ...

Error Analysis of a Pressure‐Correction Method With Explicit Time‐Stepping

International Journal for Numerical Methods in Fluids, EarlyView.
We study explicit variants of this well‐established pressure‐correction scheme for solving the Navier–Stokes equations. Step 3 is replaced by an explicit time‐integration method. We give the complete error analysis for this scheme that allows for highly efficient implementations.
