‘Reinventing’ the Beach? Lessons from a Local Development Plan in the French Riviera

The Political Quarterly, EarlyView.
Abstract Coastal squeeze is now so tangible both globally and locally that the focus of scientific debate has expanded from the erosion of beaches to the risk of their disappearance. In this context, it is crucial to explore local development plans that aim to preserve the long‐term existence of a beach.

Arc Phenomena in low-voltage current limiting circuit breakers [PDF]

, 2010
Circuit breakers are an important safety feature in most electrical circuits, and they act to prevent excessive currents caused by short circuits, for example. Low-voltage current limiting circuit breakers are activated by a trip solenoid when a critical

Protection strategy for multi-terminal DC networks with fault current blocking capability of converters [PDF]

, 2017
High voltage dc networks are a promising technology to flexibly transmit power over long distances. However, dc grid protection is still a major challenge. DC fault clearance can be mainly achieved with three devices. These are ac circuit breakers (ACCBs)

Circuit Breaker

International Journal of Innovative Science and Research Technology (IJISRT)
In the realm of microservices architecture, ensuring reliability and resilience is paramount due to the distributed nature and interdependencies of services. A key pattern employed to enhance system robustness is the circuit breaker. When a microservice experiences failures, the circuit breaker pattern detects these faults and transitions between three

Caregivers' perspectives of support needs for adolescents with fetal alcohol spectrum disorder

Children &Society, EarlyView.
Abstract Research focused on fetal alcohol spectrum disorder (FASD) is often deficit‐focused, limiting a holistic understanding of individuals' support needs. Families of adolescents with FASD also struggle to access appropriate services. Using semi‐structured interviews, the current study explored the perspectives of seven caregivers of adolescents ...

Protection and post-fault recovery of large HVDC networks using partitioning and fast-acting DC breakers at strategic locations

The Journal of Engineering, 2019
DC fault protection arrangements for a large multi-terminal HVDC (MTDC) network are proposed where fast-acting DC circuit breakers are only used at strategic locations with the large DC network to be operated interconnected but partitioned into islanded ...
