Introduction COMET (COordinated Multimedia Explanation Testbed) is an experimental system that generates interactive multimedia explanations of how to operate, maintain. and repair equipment. Our research stresses the dynamic generation of the content and form of all material presented, addressing issues in the generation of text and graphics, and in coordinating text and graphics in an integra...

The degree of empirical support of a priori plausible structures on the cointegration vectors has a central role in the analysis of cointegration. Historically, this question has been answered by classical testing of over-identifying restrictions on the cointegration space. This paper introduces an exact finite sample Bayesian procedure to calculate the posterior probability of restrictions on ...

The paper deals with a new approach to importance evaluation of descriptive texts developed in the framework of SUSY, an experimental system in the domain of text snmmarization. The problem of taking into account the reader's goals in evaluating importance of different parts of a text is first analyzed. A solution to the design of a goal interpreter capable of computing a quantitative measure o...

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.
