GOAT method: Green Orthogonal Array Tuning method

Alexandria Engineering Journal
This paper is a natural extension of our previous work and introduces an eco-efficient and integrated approach to hyper-parameter optimization (HPO) using Taguchi’s orthogonal array tuning method (OATM), which forms the basis for our GOAT (Green ...

Multiband Real-Time Coherent Optical OFDM Reception up to 110 Gb/s with 600-km Transmission

IEEE Photonics Journal, 2010
We demonstrate field-programmable gate array (FPGA)-based multiband orthogonal frequency-division multiplexing (OFDM) signal reception after 600-km standard single-mode fiber (SSMF) transmission and 400-ps differential-group delay (DGD) at 110-Gb/s.

Optimization of drilling process variables using taguchi technique for LM6 aluminium alloy

International Journal for Simulation and Multidisciplinary Design Optimization, 2022
The abrasive characteristics of LM6 alloys are difficult to machine, so designing a technology that allows for effective machining is essential. This paper aims to evaluate the effect of process variables, namely feed rate, spindle speed and drill ...

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

Advanced 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.

Construction of Column-Orthogonal Designs with Two-Dimensional Stratifications

Mathematics, 2023
For the design of computer experiments, column orthogonality and space-filling are two desirable properties. In this paper, we develop methods for constructing a new class of column-orthogonal designs (ODs) with two-dimensional stratifications on finer ...

Optimal Ramp Schemes and Related Combinatorial Objects [PDF]

, 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.
