● Deactivation of Diesel Catalyst Abstract: The first diesel catalysts, introduced in 1970s for underground mining applications, were simple oxidation catalysts designed for conversion of CO and HC. These catalysts gradually evolved into the modern diesel oxidation catalysts, optimized for PM emission reduction. Future requirements for NOx emission reduction from diesel engines call for new cat...

The issue of free-text versus controlled vocabulary is examined in this article. The history of the issue, which is seen as beginning with the debate over title term indexing in the last century, is reviewed and then attention is turned to questions which have not been satisfactorily addressed by previous research. The point is made that these questions need to be answered if we are to design r...

In this study, a new modeling method based on trapezoidal fuzzy number FAHP has been proposed to solve the problem of risk element transmission in enterprise project evaluation chain. We firstly put forward enterprise project chain risk element transmission and constructs enterprise project chain risk element transmission tetrahedron model and then proposed the theory of enterprise project eval...

Jungles generalize trees by sharing subtrees and allowing garbage. It is shown that IO context-free tree grammars generate the same jungle languages as context-free jungle grammars. Also, they define the same subsets of any algebra.

A study is reported on the consistency of the domain vocabularies created and the source documents selected by domain analysts for domain analysis using DARE (Domain Analysis and Reuse Environment). Consistency was analyzed by measuring the pairwise overlap scores between the domain analysts. The overlap scores of the vocabularies and the source documents were both found to be significantly gre...

The activity of the Ph.D. student Juri Luca De Coi involved the research field of policy languages and can be divided in three parts. The first part of the Ph.D. work investigated the state of the art in policy languages, ending up with ∙ identifying the requirements up-to-date policy languages have to fulfill ∙ defining a policy language able to fulfill such requirements (namely, the Protune p...

Metadata applications have developed local controlled vocabulary to meet information needs of users, but little is known about what vocabularies users use in searching for information. This paper reports the findings from an analysis of a digital library’s query log. The analysis addresses questions of to what extent users use controlled vocabulary in resource discovery and what non-controlled ...

Although randomized controlled trials (RCTs) play a key role in modern medicine, considerable variability exists in their quality and in the reliability (reproducibility) of their results. The present article discusses features that characterize high-quality trials, such as intent-to-treat (ITT) analysis, the avoidance of patient exclusions, and a procedure for evaluating the reliability of stu...

Purpose – This paper aims to report on an empirical case study, (single case multi-site) employing both a ‘‘hard’’ and ‘‘soft’’ method. The tangible, visible component of the study was the production of a database whose fields were to be the source of tacit knowledge emergence. Design/methodology/approach – The proposition was that the possibility for the capture of tacit knowledge was subject ...
