The leakage of tricresyl phosphate-containing engine lubricants into aircraft cabin air, either from worn or defective engine seals or under normal operating conditions, is a serious concern for both the health and safety of the cabin occupants, since the oil contains one to five percent tricresyl phosphate (TCP) esters, known neurotoxins. The exposure of pilots is a particular concern since th...

Part of vehicle interior noise is caused by the complex turbulent flow field behind a-pillar and side mirror. It excites structure window, which radiates into interior. Both aerodynamic pressure excitation acoustic sound sources in play an important role. In this work, influence both mechanisms investigated numerically a hybrid simulation on simplified car geometry. The generic model allows for...

The analysis of the structures springing systems modern vehicles showed that polymer composites are used in for which decrease curb weight is a critical indicator. use springs (suspensions) from makes it possible to reduce elastic element and increase durability while improving smoothness movement, reducing noise, increasing traffic safety. When replacing steel suspension with composite suspens...

The National Renewable Energy Laboratory (NREL) has developed a transient air conditioning (A/C) system model using SINDA/FLUINT analysis software. It captures all the relevant physics of transient A/C system performance, including two-phase flow effects in the evaporator and condenser, system mass effects, air side heat transfer on the condenser/evaporator, vehicle speed effects, temperature-d...

In a previous study we found large systematic errors (up to 40 degrees) when subjects adjusted the orientation of a horizontal test bar until it appeared parallel to a horizontal reference bar, both bars rotating about their vertical axes. The deviations increased linearly with the separation angle but vanished when the orientation of the reference bar was either parallel or perpendicular to th...

High comfort for the driver in working vehicles is an important feature as well as a demand from the drivers. Low noise level is an essential factor for the manufacturer to maintain a high standard and comfort of vehicles. In many cases the noise inside the cabin can be related to the engine orders. Hydraulic pumps and fans are also related to the engine but not necessarily integers of the engi...

Title: BEYOND RACIAL STEREOTYPES: SUBVERSIVE SUBTEXTS IN CABIN IN THE SKY Kate Marie Weber, M.A., 2008 Directed by: Dr. Richard King, Associate Professor of Musicology The 1943 film Cabin in the Sky holds an important place in cinematic history as one of the first “all-Negro” pictures produced by a major Hollywood studio. The movie musical reflects a transitional period in American racial polit...

Fatigue driving is an invisible killer in car accidents and one of the main causes traffic accidents. In order to reduce caused by fatigue, this research has developed a safety assist device prevent such research, non-contact driver drowsiness detection alert system established vehicle cabin. The real-time facial image obtained through camera installed front driver, then input NVIDIA Jetson TX2...

UNLABELLED Passengers in an aircraft cabin can have different risks of infection from airborne infectious diseases such as influenza, severe acute respiratory syndrome (SARS), and tuberculosis (TB) because of the non-uniform airflow in an aircraft cabin. The current investigation presents a comprehensive approach to assessing the spatial and temporal distributions of airborne infection risk in ...
