The coupling of scattered-bend loss in POF based the displacement measurement sensor
Sensing and Bio-Sensing Research, 2020 In this paper, a displacement sensor is proposed based on the coupling of scattering loss during the bending of fiber. We adopted a twisted structure of two fiber to couple the scattered loss which caused by bending.

redicting dynamic specifications of ADCs with a low-quality digital input signal [PDF]
, 2010 A new method is presented to test dynamic parameters of Analogue-to-Digital Converters (ADC). A noisy and nonlinear pulse is applied as the test stimulus, which is suitable for a multi-site test environment.

Dynamic specification tests for dynamic factor models [PDF]
Journal of Applied Econometrics, 2019 SummaryWe derive computationally simple expressions for score tests of misspecification in parametric dynamic factor models using frequency domain techniques. We interpret those diagnostics as time domain moment tests which assess whether certain autocovariances of the smoothed latent variables match their theoretical values under the null of correct ...
