Changes in vital signs, ventilation mode, and catecholamine use during intensive care aeromedical evacuation flights

open access: yesFrontiers in Public Health, 2023
IntroductionEspecially after (natural) disasters, local health systems are also destroyed or their ability to work is massively restricted. The transport of injured patients is therefore often necessary for further care.

The Effect of the Purge–Mainstream Density Ratio on Rim Seal Fluid Mechanics

open access: yesInternational Journal of Turbomachinery, Propulsion and Power
Significant density ratios arise in a gas turbine due to severe temperature gradients between the hot mainstream gases leaving the combustor and the superposed purge flow injected from the secondary air system. Engineers seek to minimise the ingestion of

Novel Multimodal Feedback Techniques for In-Car Mid-Air Gesture Interaction [PDF]

open access: yes, 2017
This paper presents an investigation into the effects of different feedback modalities on mid-air gesture interaction for infotainment systems in cars. Car crashes and near-crash events are most commonly caused by driver distraction.
