General Weighted Optimality of Designed Experiments
Design problems involve finding optimal plans that minimize cost and maximize information about the effects of changing experimental variables on some response. Information is typically measured through statistically meaningful functions, or criteria, of a design's corresponding information matrix. …

Statistical Methods for Reliability Data from Designed Experiments
… Industrial statisticians have been planning experiments for years to improve product quality and reliability. However, rarely do experts in the field of reliability have expertise in design of experiments (DOE) and the implications that experimental protocol have on data analysis. …

Three-mode principal component analysis in designed experiments
This dissertation is concerned with the application of a method for decomposing multivariate data, three-mode principal component analysis, to a three-way table with one observation per cell. It is based on the class of multiplicative models for three-way tables (s x t x u) whose general form has …

Statistical design of MOS VLSI circuits with designed experiments
Many methods for the statistical design and analysis of integrated circuits have been proposed over the past years. However, these methods typically require a large number of computationally expensive circuit simulator runs, and their applications are limited to small circuits.

Measurement Error in Designed Experiments for Second Order Models
Measurement error (ME) in the factor levels of designed experiments is often overlooked in the planning and analysis of experimental designs. A familiar model for this type of ME, called the Berkson error model, is discussed at length. Previous research has examined the effect of Berkson error on …

The Tessera D&R computational environment: Designed experiments for R-Hadoop performance and Bitcoin analysis
… Tessera D&R computational environment through designed experiments. ^ The base of the D&R computational environment is RHIPE, the R and Hadoop Integrated Programming Environment. R is a widely used interactive language for data analysis. Hadoop is a distributed, parallel computational …

Two-phase flow dynamical simulations and modelling
… development, computational techniques and well-designed experiments. However, there remain many modelling uncertainties mainly associated with inadequate physical prescriptions rather than with limitations of the numerical schemes. The present project addresses some of these questions, in …

An integrative approach to studying protein-protein interactions within the genome of Mycobacterium tuberculosis
… an organism. PPIs have been studied by specially designed experiments to identify pairs of proteins that are suspected to interact. Experimental approaches are quite expensive, yet still there are cases of wrongly identified protein-protein interactions. In this study, we predict PPIs …

Using generative modelling in healthcare
… various missingness scenarios via accordingly designed experiments and simulation studies. We shall proceed via introducing our method on GANs’ inversion and evaluate its performance in a newly suggested manner. Finally, we shall conclude this thesis with our main findings and future work.

New pyroelectric phenomena from graded ferroelectric barium strontium titanate thin films
… correctly predicted the results of some newly designed experiments. From our current understanding of the origin and mechanism of the new pyroelectric phenomena discussed in this study, we proposed to further simplify the structure of future pyroelectric infrared detectors by adopting a new …

Comparing k Population Means with No Assumption about the Variances
<p>In the analysis of most statistically designed experiments, it is common to assume equal variances along with the assumptions that the sample measurements are independent and normally distributed. Under these three assumptions, a likelihood ratio test is used to test for the difference in …

Eyes Up : influencing social gaze through play
… system in conjunction with specifically designed experiments, we have been able to test the system's ability to influence gaze behavior and expression recognition. Analysis of pre- and post- experimental measures reveals statistically significant increases in attention to the face and …

Neural networks as a tool for statistical modeling
… is in response surface modeling based on designed experiments. Due to the small sample sizes typically employed by response surface designs, the ability of the SHLFNN to accurately approximate the underlying model is questionable. The results of a simulation which compares the performance …

Development of a co-dispersion binder for the three-dimensional printing process to facilitate handling of ceramic casting shells in the green state
… with co-dispersions was less than 10%. Through designed experiments, performance of the co-dispersion was quantified by additional criteria such as shrinkage, warping, and binder stability. Average linear shrinkage in parts printed with co-dispersions was 0.05% after firing at 900°C. A simple …

Multiscale modeling of thin film deposition processes
… on the copper deposition. Statistically designed experiments were performed with the rotating disk electrode (RDE) apparatus. A hydrodynamic model was developed for RDE and is used to fit the kinetic parameters that are independent of the transport effect.

Contributions to the Analysis of Experiments Using Empirical Bayes Techniques
… Bayesian approach to the design and analysis of experiments. Here we address this difficulty by proposing the use of functional priors and then by working out important details for three and higher level experiments. One of the challenges presented by higher level experiments is that a factor can …

Development and modelling of weld cooling time equations.
… the cooling behaviour. A series of carefully designed experiments indicate that in practice the weld pool shape has no influence on the cooling behaviour. Evidence is presented that the level of the welding process parameters influences the level of the arc efficiency. The arc efficiency is …
