Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training
Symbolic Interaction, EarlyView.We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

Acoustical characterization of external gear pumps: comparison of spur and helical gears
, 2023 The evaluation of the noise performance of hydraulic pumps is a key aspect for manufacturers as the pump often represents one of the main noise sources in hydraulic systems on end users applications. Although sound power tests are the most accurate measurement method for the acoustical characterization of a source, study relies on a more practical and ...
