51. Estimating the Magnitude and Phase Response of a 50 GHz Sampling Oscilloscope Using the Nose-to-Nose Method
Published: 6/1/2000
Authors: Paul D Hale, Tracy S. Clement, Kevin J Coakley, Chih-Ming Wang, Donald C. DeGroot, A. P. Verdoni
Abstract: We describe estimation of the magnitude and phase response of a sampling oscilloscope over 50 Ghz bandwidth using the nose-to-nose method. The measurements are corrected for the non-ideal properties of the oscilloscope and calibration apparatus, inc ...

52. Adaptive Use of Prior Information in Inverse Problems: An Application to Neutron Depth Profiling
Published: 3/1/2000
Authors: M Levenson, Kevin J Coakley
Abstract: A flexible class of Bayesian models is proposed to solve linear inverse problems. The models generalize linear regularization methods such as Tikhonov regularization and are motivated by the ideas of the image restoration model of Johnson et al. (19 ...

53. Least-Squares Estimation of Time-Base Distortion of Sampling Oscilloscopes
Published: 12/1/1999
Authors: Chih-Ming Wang, Paul D Hale, Kevin J Coakley

54. Empirical Modeling of Electromagnetic Accoustic Transducer Data
Report Number: 5087
Published: 8/1/1999
Authors: Kevin J Coakley, A V Clark, C S Hehman
Abstract: We characterize the observed phase and amplitude of acoustic birefringence data collected with an electromagnetic acoustic transducer (EMAT). Our characterization models are extended versions of an idealized model for acoustic birefringence. In the ...

55. Empirical Modeling of Electromagnetic Acoustic Transducer Data
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5087
Published: 8/1/1999
Authors: Kevin J Coakley, A V Clark, C S Hehman

56. Uncertainty Intervals for Polarized Beam Scattering Asymmetry Statistics
Published: 7/1/1993
Authors: Kevin J Coakley, Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: In many scattering experiments, the quantity of most direct physical interest is a measure of the difference between two closely related scattering signals, each generated by a Poisson scattering process. This difference is often expressed in terms o ...

57. Micromagnetics of Domain Walls At Surfaces
Published: 1/1/1991
Authors: M Scheinfein, John Unguris, J L. Blue, Kevin J Coakley, Daniel Thornton Pierce, Robert Celotta, P J Ryan
Abstract: High-spatial-resolution magnetization maps of ferromagnetic surfaces are generated with use of scanning electron microscopy with polarization analysis (SEMPA). The structure of surface Neel walls is measured by SEMPA and compared directly to the res ...
