In this paper a class of semi-implicit predictor–corrector time integration schemes is proposed. Linear stability analysis is used to identify promising methods and these are applied to the nonlinear system of the shallow water equations on an icosahedral grid. The model used is a testbed for the future development of a more complete atmospheric model. Experiments with standard test cases from ...

We consider the development of implicit-explicit time integration schemes for optimal control problems governed by the Goldstein–Taylor model. In the diffusive scaling this model is a hyperbolic approximation to the heat equation. We investigate the relation of time integration schemes and the formal Chapman-Enskog type limiting procedure. For the class of stiffly accurate implicit–explicit Run...

A hybrid censoring scheme is a mixture of type I and type II censoring schemes. When $n$ items are placed on a life test, the experiment terminates under type I or type II hybrid censoring scheme if either a pre-fixed censoring time T or the rth (1<=r<=n&nbsp;is fixed) failure is first or later observed, respectively. In this paper, we investigate the decomposition of entropy in both hybrid cen...

The objective of this article is to further the study of journal interdisciplinarity, or, more generally, knowledge integration at the level of individual articles. Interdisciplinarity is operationalized by the diversity of subject fields assigned to cited items in the article’s reference list. Subject fields and subfields were obtained from the Leuven-Budapest (ECOOM) subject-classification sc...

There exist various different discourse annotation schemes that vary both in the perspectives of discourse structure considered and the granularity of textual units that are annotated. Comparison and integration of multiple schemes have the potential to provide enhanced information. However, the differing formats of corpora and tools that contain or produce such schemes can be a barrier to thei...

Computational modelling of metal-electrolyte reactions is central to the understanding and prediction a wide range physical phenomena, yet this often challenging owing presence numerical oscillations that arise due dissimilar reaction rates. The ingress hydrogen into metals paradigmatic example technologically-relevant phenomenon whose simulation compromised by stiffness terms, as rates vary ov...
