Lindgren T. Cabin Air Quality in Commercial Aircraft Exposure, Symptoms and Signs. Comprehensive Summaries of Dissertations from the Faculty of Medicine. MEDFARM 2003/564. Uppsala. ISBN 91-554-5631-6 The objective of the dissertation was to study the cabin environment, and identify personal and environmental risk factors, associated with symptoms, and perception of cabin air quality. Another ob...

Abstract The advanced and personalised experience that modern cars offer makes them more data-hungry. For example, the cabin preferences of possible drivers must be recorded associated to some identity, while such data could exploited deduce sensitive information about driver’s health. Therefore, drivers’ privacy taken seriously, requiring a dedicated risk assessment framework, as presented in ...

2 Aircraft cabin ventilation In early commercial jet aircraft, passenger cabins were ventilated with 100% outside air. In more recent jet aircraft, approximately 50% of the ventilation air is outside air and the remaining 50% is filtered recirculated cabinair. This development has allowed for fuel savings as well as a supposed improvement in the relative humidity of cabin air. With typical pass...

ZnO nanomaterials with different shapes were synthesized, characterized and tested in the selective monitoring of low concentration of CO and NO₂ in air. ZnO nanoparticles (NPs) and nanofibers (NFs) were synthesized by a modified sol-gel method in supercritical conditions and electrospinning technique, respectively. CO and NO₂ sensing tests have demonstrated that the annealing temperature and s...

Data pertaining to nonmotion factors affecting ride quality of transport aircraft have been obtained as part of NASA in-house and sponsored research studies carried out onboard commuter-airline and research aircraft. From these data, quantitative effects on passenger discomfort of seat width, seat legroom, change in cabin pressure, and cabin noise are presented. Visual cu_ effects are also disc...

The supply air from the airliner ventilation system is a mixture of outside air and recirculated air that passes through a high efficiency particulate air (HEPA) filter. The effectiveness of two commercial-available airliner cabin air filters were investigated under the laboratory-based measurement due to the practical restriction of airliner cabin filter test during usage. The filtration effic...

projection display, is a room-sized, five-screen system that can display both computer graphics and video images. Several Cabins connected via a broadband network form the Cabinet system. Cabinet includes video avatars—a key new technology for sharing virtual worlds. Using video avatars, we have experimentally evaluated the ability to express positional information between distant users. I mmer...

Active noise control is a technique to cancel unwanted sound using adjustable secondary sound. In active sound profiling, the target is to obtain a certain sound field or profile and the power over specific frequencies can be altered in a desired way, even by amplifying it. Active sound profiling can be used for increasing the sound quality in a passenger car, for example, by modifying the engi...

OBJECTIVE This paper reviews secondhand smoke (SHS) exposure and diseases and symptoms of the upper airway, including the sinuses. Risks to flight attendants, who were occupationally exposed until smoking was banned on all flights, are emphasised. DATA SOURCES A systematic database search was conducted; the US Surgeon General's reports and other major reviews were evaluated. Literature summar...
