A deterministic algorithm for experimental design applied to tomographic and microseismic monitoring surveys [PDF]

open access: yes, 2004
Most general experimental design algorithms are either: (i) stochastic and hence give different designs each time they are run with finite computing power, or (ii) deterministic but converge to results that depend on an initial or reference design ...

Optimal design of injection mold for plastic bonded magnet [PDF]

open access: yes, 1991
The optimal design of an injection mold for producing a stronger multipole magnet is carried out using the finite element method and the direct search method. It is shown that the maximum flux density in the cavity obtained by the optimal design is about

Multiplication Algorithms for Approximate Optimal Distributions with Cost Constraints

open access: yesMathematics, 2023
In this paper, we study the D- and A-optimal assignment problems for regression models with experimental cost constraints. To solve these two problems, we propose two multiplicative algorithms for obtaining optimal designs and establishing extended D ...

The Nonequivalent Circulant D-Optimal Designs for n=2 mod 4, n<=54, n=66 [PDF]

open access: yes, 1994
All non-equivalent circulant D-optimal designs for n ≡ 2 mod 4, n ⩽ 54 and n = 66 are given and were found by an exhaustive search. There is a unique non-equivalent circulant design for each value of n ⩽ 18, 3 for n = 26 and n = 30, 8 for n = 38, 31 for ...

Optimized Teucrium polium topical cream improves wound closure in a rat excisional model: A D-optimal design and RBF modelling approach [PDF]

open access: yesArchives of Biological Sciences
Chronic wounds require topical formulations that combine favorable physicochemical properties with measurable biological activity. In this study, a bio-based, oil-in-water cream containing Teucrium polium methanolic extract was developed and optimized ...

Optimization of Enset Fermentation in the Production of Kocho Using Response Surface Methodology

open access: yesActa Universitatis Cibiniensis. Series E: Food Technology, 2018
Response surface methodology (RSM) was used for optimization of enset fermentation process. Two numerical (time and amount of starter culture) and one categorical variable (types of starter strain) was used for evaluation of sensory quality of kocho. The

D-Optimal Design for a Causal Structure for Completely Randomized and Random Blocked Experiments

open access: yesJournal of Probability and Statistics, 2022
Most experimental design literature on causal inference focuses on establishing a causal relationship between variables, but there is no literature on how to identify a design that results in the optimal parameter estimates for a structural equation ...
