In this paper joint mean and variance beta regression models are proposed. The proposed models are fitted applying Bayesian methodology and assuming normal prior distribution for the regression parameters. An analysis of structural and real data is included, assuming the proposed model, together with a comparison of the result obtained assuming joint modeling of the mean and precision parameters.

This paper contrasts different experimental designs for revealing the neural correlates of phonological retrieval (i.e., naming). Cognitive subtraction designs require a minimum of one task pair and the comparison between tasks reveals the differing functional task components. Conjunction analysis requires a minimum of two task pairs, each differing by the same component, and this component is ...

This paper describes an experimental modular distributed manipulation system upon which one can implement a variety of control schemes. We have shown elsewhere that when one includes the nonsmooth effects of friction into a model of distributed manipulation, nonsmooth feedback laws must generally be used to control distributed manipulators. We summarize results obtained with this experimental s...

A key step in “Designing for the Consequences of Hazard” is choosing which hazards to design for. This paper argues that the Bayesian perspective is the rational and prudent framework.

Effective evaluation of educational software is a key issue for successful introduction of advanced tools in the curriculum. This paper focuses on our experience of developing and evaluating a tool for computer-assisted teaching of engineering laboratory courses. Various categories of educational software that can be used for laboratory courses are described. An example of such experimental sys...

Joint independent component analysis (jICA) can be applied within subject for fusion of multi-channel event-related potentials (ERP) and functional magnetic resonance imaging (fMRI), to measure brain function at high spatiotemporal resolution (Mangalathu-Arumana et al., 2012). However, the impact of experimental design choices on jICA performance has not been systematically studied. Here, the s...

1 NSContrast:Interface for Contrasting Multiple News Site Today, there is access to large numbers of news sites in different countries, and there are several experimental systems that integrate news articles about a particular event from multiple news sites. These systems enable a good understanding of particular events by using multiple news sites, but they ignore the characteristics of the va...

Infants' phonological acquisition during the first 18 months of life has been some 30 years. Current research themes include statistical learning mechanisms, early lexical development, and models of phonetic category perception. So far, linguistic theories have hardly been taken into account. These theories are based upon the assumption that there is a common core of innate phonological knowled...
