Fault calculations using three terminal Thevenin’s equivalent circuit
Abstract The aim of this paper is to present a systematic approach of calculating fault currents due to the switching of elements or fault impedances that involve two buses and ground. Traditionally, Thevenin’s equivalent circuits are made up of two terminals suitable for calculating the current into an element connected between both terminals of the

Analysis of a Three Phase Induction Motor Directly from Maxwell's Equations
The torque developed in a three phase AC squirrel cage motor is usually expressed in terms of resistances and reactances of the stator, the rotor, and the motor as a whole. We use Maxwell's equations to find the torque in terms of geometrical parameters.

Survival Remains High in Griffon Vultures 40 Years After Reintroduction
The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management
