Blocked regular fractional factorial designs with minimum aberration [PDF]

open access: yes, 2005
This paper considers the construction of minimum aberration (MA) blocked factorial designs. Based on coding theory, the concept of minimum moment aberration due to Xu [Statist.

Nonlinear Matroid Optimization and Experimental Design [PDF]

open access: yes, 2007
We study the problem of optimizing nonlinear objective functions over matroids presented by oracles or explicitly. Such functions can be interpreted as the balancing of multi-criteria optimization. We provide a combinatorial polynomial time algorithm for

Some Results on $s^{n-k}$ Fractional Factorial Designs with Minimum Aberration or Optimal Moments

open access: yesThe Annals of Statistics, 1991
The minimum aberration criterion is commonly used for selecting good fractional factorial designs. In this paper we obtain minimum aberration $2^{n - k}$ designs for $k = 3, 4$ and any $n$. For $k > 4$ analogous results are not available for general $n$ since the resolution criterion is not periodic for general $n$ and $k > 4$. However, it can be shown

A trigonometric approach to quaternary code designs with application to one-eighth and one-sixteenth fractions [PDF]

open access: yes, 2011
The study of good nonregular fractional factorial designs has received significant attention over the last two decades. Recent research indicates that designs constructed from quaternary codes (QC) are very promising in this regard.

Generalized resolution for orthogonal arrays [PDF]

open access: yes, 2014
The generalized word length pattern of an orthogonal array allows a ranking of orthogonal arrays in terms of the generalized minimum aberration criterion (Xu and Wu [Ann. Statist. 29 (2001) 1066-1077]).

Minimum aberration designs for discrete choice experiments [PDF]

open access: yes, 2017
A discrete choice experiment (DCE) is a survey method that givesinsight into individual preferences for particular attributes.Traditionally, methods for constructing DCEs focus on identifyingthe individual effect of each attribute (a main effect ...

Quarter-fraction factorial designs constructed via quaternary codes

open access: yes, 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.

Shaping electron beams for the generation of innovative measurements in the (S)TEM [PDF]

open access: yes, 2014
In TEM, a typical goal consists of making a small electron probe in the sample plane in order to obtain high spatial resolution in scanning transmission electron microscopy.

Polarization in the prompt emission of gamma-ray bursts and their afterglows [PDF]

open access: yes, 2006
Synchrotron is considered the dominant emission mechanism in the production of gamma-ray burst photons in the prompt as well as in the afterglow phase.
