The airbag system has become a standard equipment of vehicles recently. The purpose of airbag system is to protect the safeties of driver and passengers. How to improve the ignition timing of algorithm of airbag control at the moment of car accident occurrence is very important. In this paper, the test platform of simulation is established such as to assure the corrections of ignition timings f...

This paper describes a prototype system to visualize and animate 3D scenes from car accident reports, written in French. The problem of generating such a 3D simulation can be divided into two subtasks: the linguistic analysis and the virtual scene generation. As a means of communication between these two modules, we rst designed a template formalism to represent a written accident report. The C...

in this study, the total of 6,700 casualties by car accidents in the city of tehran, during one year period (1973) was examined. among these casualties 4,159 persons were referred to the sina hospital, of who 3,276 were males, 852 were females and the remaining persons were unknown. in terms of seriousness of the accident of these individuals involved, 24.0 per cent were treated at the out-pati...

Abstract The aim of this study is to study the kinematics of adult pedestrians and assess head injury risks based on real‐world accidents. A total of 43 passenger car versus pedestrian accidents were selected from accident databases for simulation study. According to real‐world accident investigation, accident reconstructions were conducted using multi‐body system (MBS) pedestrian and car model...

This project is about making cars more intelligent and interactive which may notify or resist user under unacceptable conditions, they may provide critical information of real time situations to rescue or police or owner himself. Driver fatigue resulting from sleep deprivation or sleep disorders is an important factor in the increasing number of accidents on today's roads. In this paper, we des...

In Germany the number of casualties in passenger car to pedestrian crashes has been reduced by a considerable amount of 40% as regards fatalities and 25% with regard to seriously injured pedestrians since the year 2001. Similar trends can be seen in other European countries. The reasons for that positive development are still under investigation. As infrastructural or behavioral changes do in g...

This paper provides a link between car following theory and the economic theory of road congestion by means of a theory of speed choice. According to this theory speed choice is based on a trade-off between the benefits (shorter travel time) and cost (higher accident risk) of driving faster. Accident risk is related to the distance to the ‘leader’ and by elaborating this relationship a number o...

A 36-year-old male involved in a car accident was found to have an embolic stroke due to a left atrial myxoma. Open heart surgery was delayed 4 weeks to decrease the risk of neurologic complications from the anticoagulation required for cardiopulmonary bypass. After resection of the myxoma, intraoperative transesophageal echocardiography found severe mitral regurgitation, which was repaired.

A case of fungal necrotizing fasciitis that appeared in an immunocompetent Mexican woman after a car accident is described. The patient did not respond to antifungal treatment and died 4 days later. The fungus was molecularly identified as a new species of Apophysomyces, namely, Apophysomyces mexicanus.
