The paper proposes the influence analysis of five types city bus body layouts on air flows formation in cabin, generated by motor compartment fan under conditions forced convection. authors conducted three tests with different boundary finite element calculation module ANSYS Fluent: input velocity from fan, temperature and environment, internal external According to results simulated field test...

Car cabin air quality monitoring can effectively he analysed using metal oxide semiconducting (MOS) gas sensors. In this paper, commercially available gas sensors are compared with fabricated Mo03-Ti02 and Moo3WO3 thin films. The laboratory tests showed that the Moo3 based sensors possessed comparable gas sensing properties. The Mo03(75%)-Ti02(25%) sensor has a response 74% higher relative to t...

BACKGROUND Exposure to particulate matter (PM) air pollution especially derived from traffic is associated with increases in cardiorespiratory morbidity and mortality. In this study, we evaluated the ability of novel vehicle cabin air inlet filters to reduce diesel exhaust (DE)-induced symptoms and markers of inflammation in human subjects. METHODS Thirty healthy subjects participated in a ra...

The objective of this study is to design and briefly investigate the cooling performances of an air conditioning system for a special purpose vehicle under various experimental conditions. An air conditioning system with two parallel refrigeration cycles consisting of two compressors and two condensers for satisfying the required cooling performance of the special purpose vehicle was tested und...

Face detection is an important preprocessing stage for automated facial recognition systems. Imaging in real world environment experience substantial variation in lighting and weather conditions. Surveillance systems are a typical example of real world imaging systems. Face detection is based upon typical haar like patterns appearing in facial images. Performance of even most successful face de...

Background: Recovery strategies are often used with the intention of preventing or minimising muscle soreness after exercise. Whole-body cryotherapy, which involves a single or repeated exposure(s) to extremely cold dry air (below -100 °C) in a specialised chamber or cabin for two to four minutes per exposure, is currently being advocated as an effective intervention to reduce muscle soreness a...

Driving simulators have been widely used to investigate driver behavior and psychophysiological responses. In this paper, we proposed to use multiple participant-operated driving simulators which communicate with each other so the platoon formed by the simulators can demonstrate realistic effects of driver-driver interaction in simulation scenarios. In our preliminary experiment, three driving ...

The present study investigated the unsteady transport of droplets exhaled by an index passenger in an aircraft cabin using the CFD simulations. A section of twin aisle cabin with seven-rows and full occupancy was studied. It was found that the expiratory droplet cloud was initially dense and moved to specific zones. The droplet concentrations were higher in these zones. The droplet concentratio...

Passive solar heating is presently a major concern of Romania groups working on building research and design. The first theoretical and experimental research studies were worked out in INCERC and used the following experimental bases: the INCERC 1 solar cabin (1974), the Campina solar houses (1976, 1977), the solar apartment buildings in Medgidia (1981) and CS 3 Bucharest solar house at INCERC ...

In order to improve the thermal comfort of passengers, thermoelectric cooling climate-controlled seats were set in passenger cabin. this study, cooler units’ performance is studied by experiment method. The heat and flow field bus cabin are analyzed four different cases (air conditioner open/closed, open/closed) using computational fluid dynamics Moreover, an has been conducted verify accuracy ...
