Measuring Second- through Fourth-Order Moments in Noisy Data
TL;DR: In this paper, the authors derive expressions for correcting second-through fourth-order moments of measured variables that are contaminated by random uncorrelated noise and apply them to an artificially produced time series as well as measurements from two upward-pointing ground-based lidar systems.

High-resolution X-ray spectroscopy and modeling of the absorbing and emitting outflow in NGC 3783
Shai Kaspi,W. N. Brandt,Hagai Netzer,Ian M. George,Ian M. George,George Chartas,Ehud Behar,Rita M. Sambruna,Rita M. Sambruna,Gordon P. Garmire,John A. Nousek +10 more
TL;DR: In this paper, the authors reanalyzed the Chandra HETGS spectrum using better flux and wavelength calibrations, along with more robust methods to demonstrate the existence of the absorption lines and determine that they are blueshifted relative to the systemic velocity by -610? 130 km s-1.

Modelling a nonlinear variable-reluctance motor drive
David A. Torrey,J.H. Lang +1 more
TL;DR: In this paper, a high-power variable-reluctance motor (VRM) and a GTO-based inverter that excites the motor were used to predict the drive performance up to frequencies were eddy currents have significant influence.

Whitecap coverage from satellite measurements: A first step toward modeling the variability of oceanic whitecaps
TL;DR: In this article, the authors present estimates of whitecap coverage on a global scale from satellite-measured brightness temperature of the ocean surface, which is a first step in a larger framework aiming at more realistic modeling of the high variability of whitecaps coverage as a function of wind speed and a suite of additional environmental and meteorological factors.

Purely rotational coherence effect and time‐resolved sub‐Doppler spectroscopy of large molecules. II. Experimental
TL;DR: In this paper, a theoretical treatment and experimental study of the phenomenon termed purely rotational coherence are presented, which arises from the thermal averaging of many single molecule coherences, with respect to their dependences on molecular parameters (rotational constants, transition dipole directions) and experimental parameters (polarization directions and temperature).
