An Efficient Method for Transient Temperature Calculation in Oil Natural Transformers Based on the Time‐Space Proper Orthogonal Decomposition

High Voltage, EarlyView.
ABSTRACT A reduced‐order model (ROM) for the temperature field based on time‐space proper orthogonal decomposition (POD) is presented to improve the computational efficiency of transient temperature rise in oil‐immersed power transformers with a complete oil natural convection cooling loop.

A multilevel Ornstein–Uhlenbeck process with individual‐ and variable‐specific estimates as random effects

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract In the present study, we extend a stochastic differential equation (SDE) model, the Ornstein–Uhlenbeck (OU) process, to the simultaneous analysis of time series of multiple variables by means of random effects for individuals and variables using a Bayesian framework.

Potential impact of Stratospheric Aerosol Injection on horticultural crop suitability in Africa

The Geographical Journal, EarlyView.
Short Abstract Global warming will be devastating for horticultural crops in Africa; however, the injection of sulphur into the atmosphere has been proposed as stop‐gap solution that may help reduce the warming. This intervention may lead to an increase (~0.2) in Suitability Index Values (SIV) of mango and tomato over West and central Africa.

Alternative Approaches for Estimating Highest‐Density Regions

International Statistical Review, EarlyView.
Summary Among the variety of statistical intervals, highest‐density regions (HDRs) stand out for their ability to effectively summarise a distribution or sample, unveiling its distinctive and salient features. An HDR represents the minimum size set that satisfies a certain probability coverage, and current methods for their computation require ...
