This paper describes the challenges and lessons learned when developing industrial-grade data translators aimed for the interfacing of power-flow programs with Electromagnetic Transients Program-type programs. It has been found that the greatest challenges to overcome include: 1) the lack, in the databases used in power-flow programs, of vital pieces of(More)

A rotating machine is a very complex device that involves electrical, mechanical and control systems. Therefore, the whole representation of a machine requires the specification of electrical and mechanical parameters, as well as control system data. The representation of the mechanical part and the control systems are only needed for low frequency(More)
The diagnosis and treatment of early arthritis is associated with improved patient outcomes. One way to achieve this is by organising early arthritis clinics (EACs).
