Uniform fractional factorial designs
, 2012 The minimum aberration criterion has been frequently used in the selection of fractional factorial designs with nominal factors. For designs with quantitative factors, however, level permutation of factors could alter their geometrical structures and ...

Precise Orbit Determination Based on the Unscented Transform for Optical Observations
Journal of Astronomy and Space Sciences, 2019 In this study, the precise orbit determination (POD) software is developed for optical observation. To improve the performance of the estimation algorithm, a nonlinear batch filter, based on the unscented transform (UT) that overcomes the disadvantages ...

Holographic aberration correction: optimising the stiffness of an optical trap deep in the sample [PDF]
, 2011 We investigate the effects of 1st order spherical aberration and defocus upon the stiffness of an optical trap tens of μm into the sample. We control both these aberrations with a spatial light modulator. The key to maintain optimum trap stiffness over a

Lymphocyte chromosomal aberration assay in radiation biodosimetry
Journal of Pharmacy and Bioallied Sciences, 2010 Exposure to ionizing radiations, whether medical, occupational or accidental, leads to deleterious biological consequences like mortality or carcinogenesis. It is considered that no dose of ionizing radiation exposure is safe.

Minimum aberration designs of resolution III
, 2002 In this article we prove several important properties of 2^{k-p} minimum aberration (MA) designs with k>2, where n=2^{k-p} is the number of runs. We develop a simple method to build MA designs of resolution III. Furthermore, we introduce a simple relationship, based on product of polynomials, for computing their word-length patterns.

Quarter-fraction factorial designs constructed via quaternary codes
, 2009 The research of developing a general methodology for the construction of good nonregular designs has been very active in the last decade. Recent research by Xu and Wong [Statist.
