This paper shows that one can reason at a meta level about the structure of object-oriented source code in a language-independent way. To achieve this, we propose a language-independent meta-level interface to extract complex information about the structure of the source code. This approach is valid

Getting an initial understanding of the structure of a software system, whether it is for software maintenance, evolution or reengineering purposes, is a nontrivial task. We propose a lightweight approach to delve a system's source code automatically and efficiently for relevant concepts of interest

2004).

Single-site homogeneous catalysts need to be activated by a co-catalyst or counterion. The high activity imparted by methylaluminoxane (MAO) has caused it to be one of the most important co-catalysts. In fact it can be argued that the success of the metallocenes is largely due to the discovery of MA

This paper addresses the problem of mapping the structure of a gas distribution by creating concentration gridmaps from the data collected by a mobile robot equipped with gas sensors. By contrast to metric gridmaps extracted from sonar or laser range scans, a single measurement from a gas sensor pro

Capability passing processes model global applications in a way that decouples the global agreement aspects of protocols from the details of how the communications are actually made. It relies on a restricted API or programming language and on the exchange of digital certificates representing capabi

The 1997 International Quaternary Union (INQUA) symposium on paleoglaciology is the basis of this book, which is meant to help foster communication and cooperative work between glacial geologists and glaciologists. This objective is well chosen because Ð as the editors state in their preface Ð ªin t

Progress towards a better understanding of groundwater circulation and transport processes in aquifers demands a multidisciplinary approach to a host of unresolved problems. Although much progress has been made within recent years in interpreting the dynamic character of groundwater systems, many ke

Our research strategy has been to identify generic tasks--basic combinations of knowledge structures and inference strategies that are powerful for solving certain kinds of problems. Our strategy is best understood by considering the "interaction problem", that representing knowledge for the purpose

A facile homologation procedure for the conversion of carbonyl compounds into ketene-O,S-acetals is described. These intermediates are readily converted into ketene-O-silyl,S-acetals, thioesters, and carboxamides.
