Weather effect considerations in reliability evaluation of electrical transmission and distribution systems
The weather environment has a significant impact on the reliability of a power system due to its effect on the system failure mechanisms of overhead circuits and on the operational ability of an electric power utility. The physical stresses created by weather increase the failure rates of …

Food foraging in adult parasitoid Cotesia rubecula : how sugar sources contribute to survival and reproduction / by Gitta Siekmann.
… food and extrinsic mortality factors such as adverse weather conditions and predation, so the need for food must be studied in relation to a species' adaptation to its environment. Concentrations of sugar sources may distract wasps from host-foraging when the density of hosts is low. This has …

Passenger-Centric Ground Holding : including connections in ground delay program decisions
… overall capacity at an airport is reduced due to adverse weather conditions or other circumstances is a well-studied problem in Air Traffic Flow Management, but not from the passenger's perspective. We propose a Passenger-Centric Ground Holding (PCGH) model, which considers both the number of …

Spatiotemporal Generalized Additive Model: Investigating Weather-Related Road Crashes in Southern Finland
… pose a serious safety risk, particularly under adverse weather conditions. Having a deeper understanding of crash patterns and underpinning their connection to different meteorological factors is useful for targeted safety interventions. Many types of statistical and machine learning models seek …

Towards situation-aware driving style adaptation
… the influence of contextual factors, especially adverse weather conditions, and oncoming traffic, on automated driving functions remains limited. To address this gap, a driving simulator study (N = 42) was carried out to examine lateral driving style preferences for autonomous vehicles under …
