A hybrid system for detecting driver drowsiness was examined by using piezofilm movement sensors integrated into the car seat, seat belt and steering wheel. Statistical associations between increase in the driver drowsiness and the non-invasive and conventional physiological indicators were investigated. Statistically significant associations were established for the analysed physiological indi...

Received: June 06, 2017 Revised: July 05, 2017 Accepted: July 19, 2017 Abstract: Introduction: The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable po...

conclusions the seatbelt wearing rate among the study participants was much lower than the 90% rate reported among iranian drivers in 2010. mandating seatbelt use, as in most countries, will be more effective if a combination of factors such as changes in vehicle design, road safety, and driver and passenger behavior are taken into account. background seatbelts are a relatively low-cost safety ...

Finite Element Analysis (FEA) was used to model viscoelastic effects in the compression of polyurethane (PU) foam. Modelling of the impact compression of foam cubes predicted that a compressed region propagated through the sample, causing step increases in the stress traces. Modelling of head impacts on gymnastic ‘crash’ mats, made of PU chip foam, revealed that the majority, but not all, of th...

AIMS To assess whether cancer incidence and mortality in chronic obstructive lung diseases were increased in the Swedish polyurethane foam industry cohort, updated with 11 more years of follow up. METHODS The mortality and cancer incidence (1959-98) experienced by a cohort of 4175 male and female employees employed for at least one year in the period 1959-87 at one of nine Swedish polyurethan...

Current ATD positioning practices depend on seat track position, seat track travel range, and design seatback angle to determine appropriate occupant position and orientation for impact testing. In a series of studies conducted at the University of Michigan Transportation Research Institute, driver posture and position data were collected in forty-four vehicles. The seat track reference points ...

ARTICLE INFO An agricultural tractor seat with passive suspension system gives a number of advantages when compared with currently available seat designs. Analysis on the vibration of tractor seat suspension system by using the different types of the suspension system is carried out for the different types of operation and analyze the suspension system separately to find out the reduction in th...

The literature on rigid polyurethane foam has been reviewed with an emphasis on the gaseous products generated under various thermal decomposition conditions and the toxicity of those products. This review is limited to publications in English through 1984. Carbon monoxide (CO) and hydrogen cyanide (HCN) were the predominant toxicants found among more than a hundred other gaseous products. The ...
