Chemists sound warning on sponsorship of exhibitions

Evaluating warning sound urgency with reaction times.

It is well-established that subjective judgments of perceived urgency of alarm sounds can be affected by acoustic parameters. In this study, the authors investigated an objective measurement, the reaction time (RT), to test the effectiveness of temporal parameters of sounds in the context of warning sounds. Three experiments were performed using a RT paradigm, with two different concurrent visu...

The Chemists' War on Disease

For nearly a century and a half scientists have been studying ways of immunizing people against various diseases by artificial methods. Working mostly by trial and error they have devised reasonably safe vaccines and antisera for many diseases with a resulting spectacular decrease in mortality. T h e usual proceedure for vaccination is to inject the patient with the diseases-producing organisms...

IROS 2002 Workshop on Robots in Exhibitions

Based on the successful hardware and software architecture of Care-O-bot [7] [9], a new generation of mobile robots has been designed at Fraunhofer Institute of Manufacturing Engineering and Automation (IPA). Three robots have been created to communicate with and to entertain visitors in a museum. Their tasks include welcoming visitors, leading a guided tour through the museum or playing with a...
