This paper explores the role of one-at-a-time experimentation in parameter design of engineering systems. The focus is on degree of improvement achieved rather than on efficiency in estimating model parameters. The performance of adaptive one-at-a-time plans is compared with the performance of orthogonal arrays through computer simulations based on data from 66 response variables in 27 full fac...

Orthogonal matrix has shown advantages in training Recurrent Neural Networks (RNNs), but such matrix is limited to be square for the hidden-to-hidden transformation in RNNs. In this paper, we generalize such square orthogonal matrix to orthogonal rectangular matrix and formulating this problem in feedforward Neural Networks (FNNs) as Optimization over Multiple Dependent Stiefel Manifolds (OMDSM...

In this paper, we propose an orthogonal scan chain embedded into the RTL design described by Verilog. We first construct the data path graph from the embedded scan chains and then find all the orthogonal scan paths with the minimum weighted cost. These paths share with original data paths as possible. Finally, we create a stack form to reconstruct all the orthogonal scan paths to manage the I/O...

This technical note deals with a priori estimation of efficiency of functional magnetic resonance imaging (fMRI) designs. The efficiency of an estimator is a measure of how reliable it is and depends on error variance (the variance not modeled by explanatory variables in the design matrix) and the design variance (a function of the explanatory variables and the contrast tested). Changes in the ...

Nearly every theory of causal induction assumes that the existence and strength of causal relations needs to be inferred from observational data in the form of covariations. The last few decades have seen much controversy over exactly how covariations license causal conjectures. One consequence of this debate is that causal induction research has taken for granted that covariation information i...

the ultrasound assisted emulsification microextraction (usaeme) method followed byinductively coupled plasma-atomic emission spectrometry (icp-aes) was used for preconcentration anddetermination of bismuth (bi), indium (in) and lead (pb) in the plant azolla filiculoides lam. calix [4] pyrrole was used as a chelating agent and tetrachloroethylene was selected as extraction solvent. the main para...

enhanced oil recovery using nitrogen injection is a commonly applied method for pressuremaintenance in conventional reservoirs. numerical simulations can be practiced for the prediction ofa reservoir performance in the course of injection process; however, a detailed simulation might takeup enormous computer processing time. in such cases, a simple statistical model may be a goodapproach to the...

nanostructured ruo2 powders were synthesized via a hydrothermal method at 180 °c for 12 h using 1 and 2 m naoh aqueous solutions. the structure of the obtained nanomaterials was investigated by powder x-ray diffraction (pxrd) technique. the morphology the obtained materials were studied by field emission scanning electron microscope (fesem). the technique showed that with changing the reaction ...
