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...

This paper presents a multi-reference noise reduction system for use in a vehicle. It is aimed at enhancing the driver’s speech in noisy driving environments for applications such as voice commands or hands free phone. First, our system objective is briefly presented as well as the problems of classical techniques, like Beamforming, may face in such a harsh environment as a vehicle cabin. Secon...

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...

UNLABELLED Quick information on airborne infectious disease transmission in airliner cabins is essential to reduce the risk of infection of passengers and crew members. This investigation proposed a one-dimensional analytical model that can predict the longitudinal transmission of airborne contaminants or disease viruses inside an airliner cabin. The model considered both diffusive and convecti...

in this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. to achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. the length of gasper air flow was compared with the distance between gasper outlet and...

Five persons contracted tick-borne relapsing fever after staying in a cabin in western Montana. Borrelia hermsii was isolated from the blood of two patients, and Ornithodoros hermsi ticks were collected from the cabin, the first demonstration of this bacterium and tick in Montana. Relapsing fever should be considered when patients who reside or have vacationed in western Montana exhibit a recur...

Worldwide people are exposed to toxic ultrafine particles (UFP, with diameters (dp) less than 100 nm) and nanoparticles (NP, dp < 50 nm) under a variety of circumstances. To date, very limited information is available on human exposure to freshly emitted UFP and NP while traveling on major roads and freeways. We report in-cabin and outdoor measurements of particle number concentration and size ...

BACKGROUND Minimally invasive surgery in the field of traumatic vascular injury diagnosis and treatment has achieved good results. This study was designed to determine whether pre-hospital emergency intervention is feasible for vascular injury in a field intervention cabin under the condition of war or a disaster site. METHODS Different types of animal experiments of vascular injury intervent...

Abstract Purpose The goal of this work is to propose a local Active Noise Control system for an aircraft seat’s headrest. This should be able extend the quiet zone beyond physical microphones that can placed behind passenger’s head due space constraints. Furthermore, control algorithm perform efficiently when non-linear phenomena exist during sound propagation. Methods A functional link neural ...
