Summery We provide a comparison of the relative merits of video and infrared based methods for collecting pedestrian movements from the real world and also from experimental environments. We describe the underlying technological basis of both methods and the tools we have developed to help in collection and analysis of the data. The desire to collect such data is driven by the need of modellers and...
The quality of component-based systems highly depends on how effectively testing is carried out. To achieve the maximal testing effectiveness, this paper presents a product line based aspect oriented approach to unit testing. The aspect product line facilitates the automatic creation of aspect test cases that deal with specific quality requirements. An expandable repository of reusable aspect test...
Mismatches between pre-qualified existing components and the particular reuse context in applications are often inevitable and have been a major hurdle of component reusability and smooth composition. Although component adaptation has acted as a key solution of eliminating these mismatches, existing practices are either only capable for adaptation at a rather simple level, or requires too much intervention...
In 1994, the European Space Agency solicited major space agencies and laboratories to provide two comet landers for its Rosetta mission to be launched in 2003. The goal of this mission is to carry out extensive scientific analysis of the comet P/Wirtanen following a rendezvous in 2011.NASA and CNES are proposing one of the two landers: Champollion.The highest science priorities of Champollion are...
