Impact of modulation on CMB B-mode polarization experiments (2008)

Brown, Michael L., Challinor, Anthony, North, Chris E., Johnson, Bradley R., O'Dea, Daniel, Sutton, David

We investigate the impact of both slow and fast polarization modulation strategies on the science return of upcoming ground-based experiments aimed at measuring the B-mode polarization of the CMB....

Likelihood methods for the combined analysis of CMB temperature and polarisation power spectra (2006)

Percival, Will J., Brown, Michael L.

We consider the shape of the likelihood and posterior surfaces to be used when fitting cosmological models to CMB temperature and polarisation power spectra measured from experiments. In the limit of...

An Enlarged Cosmic Shear Survey with the William Herschel Telescope (2004)

Massey, Richard, Refregier, Alexandre, Bacon, David J., Ellis, Richard, Brown, Michael L.

We report the results of a cosmic shear survey using the 4.2m William Herschel Telescope on La Palma, to a depth of R=25.8 (z~0.8), over 4 square degrees. The shear correlation functions are measured...

Software Systems Safety Design Guidelines and Recommendations. (1998)

Brown, Michael L.

Software Systems Safety is a discipline within System Safety concerned with the potential safety risks associated with software and computers in safety critical applications. In recent years, a...

Robust Line Estimation With Errors in Both Variables

Michael L. Brown

The estimator holding the central place in the theory of the multivariate "errors-in-the-variables" (EV) model results from performing orthogonal recession on variables rescaled according to the...
