We propose a method to improve existing color-difference formulas with additional visual data from color discrimination experiments. Color-difference formulas are treated as mean functions of Gaussian processes, and the visual data are considered as observations of these processes. Gaussian process regression is applied to predict unknown color differences. The method was evaluated with a combi...

A new colour difference dataset has been developed to address the specific needs of the graphic arts industry. An experiment has been designed with 1288 colour pairs. Concretely 46 colour centres of the Fogra media wedge and 28 randomly intraand supra threshold test colours around each of them have been observed by 32 observers. The pair comparison constant stimuli method has been used by means...

Functional hypercorticism (FH) is characterized with visceral body fat distribution (VFD), hypersensitive hypothalamicpituitary-adrenal (HPA) axis with increased sensitivity to stimuli and decreased sensitivity to inhibition, reduced cortisol suppression during OGTT, hyperplasia of the adrenal glands and indicates positive dependence on the age. The aim of this study was to determine the relati...

Groundwater in Bangladesh is contaminated with Arsenic, which occurs naturally in alluvial and deltaic sediments. The first official detection in 1993 and subsequent confirmation after 1995 of high levels of Arsenic in numerous shallow and deep wells in various parts of the country has raised serious health concerns. Recent investigations, though incomplete, confirm that the occurrence of Arsen...

Operational Modal Analysis, also known as Output Only Modal Analysis, has for several years been used for extracting modal parameters of mechanical structures. In this paper, an overview of the Frequency Domain Decomposition (FDD) technique and the Stochastic Subspace Identification (SSI) technique is given. Use of the recently developed projection channel technique in combination with the SSI ...

Operational Modal Analysis, also known as Output Only Modal Analysis, has in the recent years, been used for determination of modal parameters of civil engineering structures and is now becoming widely used also for mechanical structures. The advantage of the method is that no artificial excitation needs to be applied to the structure, or force signals to be measured. In this paper, the non-par...

We investigate the Bayesian Information Criterion (BIC) for variable selection in models for censored survival data. Kass and Wasserman (1995) showed that BIC provides a close approximation to the Bayes factor when a unit-information prior on the parameter space is used. We propose a revision of the penalty term in BIC so that it is de ned in terms of the number of uncensored events instead of ...
