Eddy Current Position Measurement in Harsh Environments: A Temperature Compensation and Calibration Approach [PDF]
SensorsEddy current displacement sensors (ECDSs) are widely used for the noncontact position measurement of small displacements (lift-offs). Challenges arise with larger displacements as the sensitivity of the ECDSs decreases.

Positive definite measures [PDF]
Proceedings of the American Mathematical Society, 1963 In this paper we prove two theorems relating positive definite measures to induced representations. The first shows how the injection of a positive definite measure on a topological group H into a containing locally compact group G in which H is closed gives rise to induced representations.
