Calculation of d- and q-axis inductances of PM brushless ac machines accounting for Skew [PDF]
, 2005 A hybrid two-dimensional (2-D) finite-element/analytical technique is described for predicting the d-axis and q-axis inductances of permanent magnet (PM) brushless ac machines, with due account for the influence of skew.

Remote operations and interactions for systems of arbitrary dimensional Hilbert space: a state-operator approach [PDF]
, 2001 We present a systematic simple method for constructing deterministic remote operations on single and multiple systems of arbitrary discrete dimensionality. These operations include remote rotations, remote interactions and measurements.

A dual-mass capacitive-readout accelerometer operated near pull-in [PDF]
, 2010 A mechanical two-mass configuration and a readout circuit for a single-axis capacitive-readout accelerometer with ΣΔ force-feedback is presented. The system reduces electrical and quantisation input-referred noise through the use of negative springs ...
