Measuring and controlling medical record abstraction (MRA) error rates in an observational study
BMC Medical Research Methodology, 2022 Abstract Background Studies have shown that data collection by medical record abstraction (MRA) is a significant source of error in clinical research studies relying on secondary use data. Yet, the quality of data collected using MRA is seldom assessed.

MRAS Observers for Sensorless Control of Doubly-Fed Induction Generators
IEEE Transactions on Power Electronics, 2008 This paper addresses the analysis and performance of several model reference adaptive system (MRAS) observers for sensorless vector control of doubly-fed induction machines. Small signal models allow the formal analysis of the observers for a given dynamic.
