Bieten KI‐basierte Surrogatmodelle einen Mehrwert für die Prozessoptimierung? — Untersuchungen zu praktischen Anwendungsbeispielen im C4‐Verbund Can AI‐based surrogate models offer added value for process optimization? — Investigations into practical application examples in the C4‐Verbund

Chemie Ingenieur Technik, EarlyView.
KI‐basierte Surrogatmodelle ermöglichen die Echtzeitoptimierung chemischer Prozesse durch die präzise Abbildung komplexer Zusammenhänge bei reduzierter Rechenzeit. Anhand zweier industrieller Anwendungsfälle aus der C4‐Chemie wird das Potenzial modellbasierter Optimierung systematisch demonstriert.

Optimal subsampling for regression with mixed‐type predictors

Canadian Journal of Statistics, EarlyView.
Abstract Subsampling has emerged as an appealing strategy to mitigate the computational and storage challenges imposed by large datasets. Recent subsampling techniques have shown notable computational gains for data dominated by numerical predictors. However, real‐world datasets frequently contain both numerical and categorical predictors.

Order restricted row‐column cluster randomized design

Canadian Journal of Statistics, EarlyView.
Abstract This research introduces a novel two‐stage cluster randomized design, the order restricted row‐column cluster randomized design. The new design builds upon the cluster randomized block design by incorporating a second layer of blocking, achieved through ranking cluster units that are randomly sampled from the population.

The life and work of Ernest Sydney Keeping

Canadian Journal of Statistics, EarlyView.
Abstract This article reviews the life and contributions of Ernest S. Keeping (1895–1984), a British‐born physicist who became a mathematics professor at the University of Alberta in 1929. He played a pivotal role in shaping the university's Mathematics Department, serving as its head from 1954 to 1961, and continuing to teach until 1970, nine years ...

CEO Duality and Corporate Social Responsibility. A Literature Review With a Focus on Country Effects

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT In recent years, many researchers have become interested in the relationship between CEO duality (where one individual serves as both CEO and board chair) and CSR outcomes. Given the varied research results, this structured literature review concentrates on the country effects of this dynamic link.
