A catalog of optimal foldover plans for constructing U-uniform minimum aberration four-level combined designs

Journal of Applied Statistics, 2018
The foldover plan is a transformation map for adding a foldover design to the initial design, thus resulting in a combined design which can be used for breaking the links between aliased effects.

Generalised minimum moment aberration for designs with both qualitative and quantitative factors

Stat
The minimum moment aberration and the minimum Lee‐moment aberration criteria are two popular conceptually simple and computationally cheap criteria for selecting good designs.

Minimum and absolute minimum spherical aberration of a simple, thin lens

American Journal of Physics, 1980
Traditional treatments of third-order spherical aberration of a thin lens express the results in terms of a function Ls, involving a lens shape factor q and an object-image position factor p. The function Ls is defined in terms of the difference of the reciprocal paraxial and zonal image distances instead of the difference in distances, which is ...

Sensitivity of minimum variance beamforming to tissue aberrations

2008 IEEE Ultrasonics Symposium, 2008
Minimum variance beamformers adapt to the received data. In the case of perfect data, this beamformer can produce images with better point and edge definitions than conventional delay-and-sum beamformers. But in medical ultrasound imaging, the quality of the data is often corrupted by aberration.

Split-Plot Fractional Designs: Is Minimum Aberration Enough?

Journal of Quality Technology, 2006
Split-plot experiments are commonly used in industry for product and process improvement. Recent articles on designing split-plot experiments concentrate on minimum aberration as the design criterion. Minimum aberration has been criticized as a design criterion for completely randomized fractional factorial design and alternative criteria, such as the ...

Quadrupole-Octopole Aberration Correctors with Minimum Fields

Review of Scientific Instruments, 1971
Magnetic quadrupole-octopole systems are treated theoretically. A technique is given for finding the minimum octopole field that will correct any geometrical aberration of any orthogonal quadrupole system. It is demonstrated with the correction of aperture aberration and coma in anamorphotic and orthomorphic objective type systems. Further minimization
