TRANSMISSION LINE RELIABILITY MODELING INCORPORATING EXTREME ADVERSE WEATHER CONSIDERATIONS
… lines, which incorporates normal and bad weather conditions. The two indices of system average failure rate and system average outage duration are evaluated for this model using a Markov approach, an approximate equations method and Monte Carlo simulation. The results show that a very …

Human-centered systems analysis of aircraft separation from adverse weather
Adverse weather significantly impacts the safety and efficiency of flight operations. Weather information plays a key role in mitigating the impact of adverse weather on flight operations by supporting air transportation decision-makers' awareness of operational and mission risks. The emergence of …

Informal urban settlements, adverse weather events and adaptation : responses to incidents of flash flooding by residents in Eerste Fabriek, Mamelodi
The adverse impacts of climate change, mainly droughts and floods that affect agriculture activities, are pushing rural households to migrate to urban areas. Through this rural push, people move to the city to search for work, better economic opportunities, and a higher standard of living to …

Data-driven flight path rerouting during adverse weather: Design and development of a passenger-centric model and framework for alternative flight path generation using nature inspired techniques
… negatively impacts flight operations globally is adverse weather. To reduce the impact of adverse weather, avoidance procedures such as finding an alternative flight path can usually be carried out. However, such procedures usually introduce extra costs such as flight delay. Hence, there exists a …

A comprehensive optimization methodology for strategic environmental sensor station locations
Adverse weather poses a significant threat to transportation safety. Road weather information systems (RWIS) aim to mitigate the impact of adverse weather by detecting spatiotemporal variations of weather and/or road pavement conditions in real time. Due to the lack of a detailed, unified guideline …

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 …
