Statistical post‐processing of operational dual‐resolution wind‐speed ensemble forecasts

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The performance of raw and post‐processed 50‐member medium‐ and 100‐member extended‐range 10‐m wind‐speed forecasts of the European Centre for Medium‐Range Weather Forecasts and their various dual‐resolution combinations is investigated. Results show that post‐processing improves skill and reduces the differences between the various configurations ...

Bounds for Trivariate Copulas with Given Bivariate Marginals

open access: yesJournal of Inequalities and Applications, 2008
We determine two constructions that, starting with two bivariate copulas, give rise to new bivariate and trivariate copulas, respectively. These constructions are used to determine pointwise upper and lower bounds for the class of all trivariate copulas ...

Continuous Exchangeable Markov Chains, Idempotent and 1-Dependent Copulas

open access: yesMathematics
New copula families are constructed based on orthogonality in L2(0,1). Subclasses of idempotent copulas with square integrable densities are derived.

Managing Competency‐Based Resistance in Video‐Mediated L2 Peer Feedback Sessions

open access: yesTESOL Quarterly, EarlyView.
Abstract Though there is growing empirical evidence on managing advice resistance as an institutional work of higher status party with superior epistemic knowledge domain (e.g., trainer) across diverse settings (e.g., supervision meetings), there is still a lack of research on how second language (L2) learners handle peer resistance in real time once ...

Lorenz-generated bivariate Archimedean copulas

open access: yesDependence Modeling, 2020
A novel generating mechanism for non-strict bivariate Archimedean copulas via the Lorenz curve of a non-negative random variable is proposed. Lorenz curves have been extensively studied in economics and statistics to characterize wealth inequality and ...

On approximating copulas by finite mixtures

open access: yes, 2018
Copulas are now frequently used to approximate or estimate multivariate distributions because of their ability to take into account the multivariate dependence of the variables while controlling the approximation properties of the marginal densities ...

Review of Regina Pustet : Copulas: universals in the categorization of the lexicon: (Oxford University Press 2003; 262pp) [PDF]

open access: yes, 2007
The renowned Grimm Dictionary (1854-1961) makes the statement that the German copula sein (to be) is “the most general and colourless of all verbal concepts” (der allgemeinste und farbloseste aller verbalbegriffe).

Metalinguistic Awareness in the EFL Classroom and Beyond: Exploring the Potential of Translation Tasks

open access: yesTESOL Quarterly, EarlyView.
Abstract Current trends encouraging a move away from monolingual teaching have sparked a renewed interest in the role of translation in language instruction. Yet, there are few theoretically and empirically grounded proposals regarding specific uses of translation in the language classroom.

Discrete copulas and quasi-copulas

open access: yes, 2022
The thesis gives a brief introduction to two dimensional copulas and related functions. Firstly, we present copulas, their usage and according history. Furthermore, in the text we include some examples and visual representations for this purpose. Copulas are cumulative distribution functions defined on the unit square with marginal distributions which ...

Optimal Scheduling of Data Centre Integrated Energy Systems Considering Electric‐Thermal Demand Response Under Icing Uncertainty

open access: yesEnergy Internet, EarlyView.
ABSTRACT Extreme icing disasters increasingly undermine the reliability of integrated power and heat networks by causing line outages, supply shortages and sharp thermal load fluctuations. To address these challenges, this paper proposes a comprehensive optimisation framework that exploits the spatiotemporal flexibility of data centres for coordinated ...
