An audit to determine the clinical effectiveness of a pathway for managing wound infection [PDF]
Prevention of wound infection is a key objective in the planning of care for patients with wounds. The potential for wound infection, particularly in chronic wounds that are heavily contaminated with bacteria, can be high (Bowler et al, 2001).

Analysis of a Brushless Wound Rotor Synchronous Machine Employing a Stator Harmonic Winding
This study proposes a new topology for brushless operation of a wound rotor synchronous machine (WRSM) employing a stator harmonic winding. It is based on generating an additional six-pole magneto-motive force component without the use of an inverter. In

Rotor position estimation of wound‐rotor synchronous starter/generator
This study proposes a novel rotor position estimation method for wound‐rotor synchronous starter/generator (WSSG). At starting stage, WSSG needs a resolver to obtain main generator (MG)'s rotor position. However, the use of resolver increases starting system's complexity, volume, weight and cost. In order to solve this problem, a new kind of MG's rotor
