Full-scale furnished cabin fires have been studied experimentally for the purpose of characterising the post-crash cabin fire environment by the US Federal Aviation Administration for many years. In this paper the Computational Fluid Dynamics fire field model SMARTFIRE is used to simulate one of these fires conducted in the C-133 test facility in order to provide further validation of the compu...

This paper describes a wireless sensor network prototype with the use of reconfigurable hardware for airliner cabin environment research. Commercial airplane passengers and crews breathe a mixture of outside and re-circulated air, similar to many homes and offices. But the cabin environment is unique, due to the proximity of the passengers, the need for cabin pressurization, the low humidity, a...

The present study investigates linear and volatile (nonlinear) correlations of firstorder autoregressive process with uncorrelated AR (1) and long-range correlated CAR (1) Gaussian innovations as a function of the process parameter (θ). In the light of recent findings [1], we discuss the choice of CAR (1) in modeling daily temperature records. We demonstrate that while CAR (1) is able to captur...

AIMS To investigate whether length of employment as a cabin attendant was related to breast cancer risk, when adjusted for reproductive factors. METHODS Age matched case-control study nested in a cohort of cabin attendants. The cases were found from a nationwide cancer registry (followed up to end of year 2000) and the reproductive factors (age at first childbirth and number of children) from...

Vehicle Heating, ventilation, and air conditioning (HVAC) systems can accumulate recirculate highly infectious respiratory diseases via aerosols. Integrating Ultraviolet Subtype C (UVC) light-emitting diodes (LEDs) to complement automobile HVAC protect occupants from developing allergies, experiencing inflammatory problems, or acquiring by inactivating pathogenic organisms. UVC add little no st...

Robust fundamental frequency estimation in adverse conditions is important in various speech processing applications. In this paper a new pitch detection algorithm (PDA) based on the autocorrelation of the Hilbert envelope of the LP residual [1] is compared to another well established algorithm from Goncharoff [2]. A set of evaluation criteria is collected on which the two PDA algorithms are co...

The MPI CyberMotion Simulator provides a unique motion platform, as it features an anthropomorphic robot with a large workspace, combined with an actuated cabin and a linear track for lateral movement. This paper introduces the simulator as a tool for studying human perception, and compares its characteristics to conventional Stewart platforms. Furthermore, an experimental evaluation is present...

The study of airflow and contaminant transport in airliner cabins is very important for creating a comfortable and healthy environment. This paper shows the results of such a study by conducting experimental measurements and numerical simulations of airflow and contaminant transport in a section of half occupied, twin-aisle cabin mockup. The air velocity and air temperature were measured by ult...

People with low income often experience higher exposures to air pollutants. We compared the exposure to particulate matter (PM1, PM2.5 and PM10), Black Carbon (BC) and ultrafine particles (PNCs; 0.02-1μm) for typical commutes by car, bus and underground from 4 London areas with different levels of income deprivation (G1 to G4, from most to least deprived). The highest BC and PM concentrations w...
