Optimal Ramp Schemes and Related Combinatorial Objects [PDF]

open access: yes, 2017
In 1996, Jackson and Martin proved that a strong ideal ramp scheme is equivalent to an orthogonal array. However, there was no good characterization of ideal ramp schemes that are not strong.

Nested Orthogonal Arrays

open access: yes, 2016
Orthogonal Arrays allow us to test various levels of each factor and balance the different factors so that we can estimate interactions as well as first order effects. There is a trade-off between how well we can sample different levels of each factor and how many interactions we are able to estimate.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Orthogonal Genetic Algorithm for Planar Thinned Array Designs

open access: yesInternational Journal of Antennas and Propagation, 2012
An orthogonal genetic algorithm (OGA) is applied to optimize the planar thinned array with a minimum peak sidelobe level. The method is a genetic algorithm based on orthogonal design.

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Feasibility of Orthogonal Taguchi Arrays for Determining Parameter Trends in MDT

open access: yesCurrent Directions in Biomedical Engineering
Huge parameter studies are usually conducted to optimize and characterize systems for steering magnetic nanoparticles in magnetic drug targeting (MDT). Thus, many simulations or measurements are needed to determine the system which is time-consuming and ...

Matroidal Entropy Functions: A Quartet of Theories of Information, Matroid, Design, and Coding

open access: yesEntropy, 2021
In this paper, we study the entropy functions on extreme rays of the polymatroidal region which contain a matroid, i.e., matroidal entropy functions. We introduce variable strength orthogonal arrays indexed by a connected matroid M and positive integer v

Photoswitching Conduction in Framework Materials

open access: yesAdvanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Application of Taguchi Method in Design of Surface Eddy Current Probes for Diagnostics of Power Equipment [PDF]

open access: yesProblems of the Regional Energetics
The article’s aim is to create a method of reducing the influence on the surface eddy current probes output signal of a number of interfering parameters without their elimination, to ensure its stability, which is achieved as a result of computer search
