Linear Synchronous Reluctance Motor—A Comprehensive Review
, 2017 Linear synchronous reluctance motors (LSRELMs) are becoming an attractive alternative for linear induction motors (LIMs), linear synchronous motors (LSMs), and linear switched reluctance motors (LSRMs). This paper reviews the scientific status, development, and future scope of the LSRELMs.

Reputational Risk: An Investigation Into How Environmental Failures Drive Stock Price Crashes
Business Strategy and the Environment, EarlyView.ABSTRACT The study examines the relationship between stock price crashes and firm environment reputational risk. Using a large sample of US listed firms, covering a time span from 2007 to 2021, we test the effect of environmental reputation risk on three measures for the stock price crash risk (NEGCSK, DRUV, and CRASH).

Comparison of a Reduced-Order Observer and a Full-Order Observer for Sensorless Synchronous Motor Drives [PDF]
, 2012 Two back-electromotive-force (EMF)-based position observers are compared for motion-sensorless synchronous motor drives: the reduced-order observer and the adaptive full-order observer. A stabilizing gain is proposed for the adaptive full-order observer,
