We are developing a system that aims to perform the same inferences as a human reader, on car-crash reports. More precisely, we expect it to determine the causes of the accident as they appear from the text. We describe the general semantic framework in which our study takes place, the linguistic and semantic levels of analysis, and the inference rules used by the system. Mots-clés : sémantique...

To evaluate the performance and scalability of Altair RADIOSS on Intel® Xeon® processor E7-4890 v2, Altair benchmarked RADIOSS using a modified publicly available crash simulation model of a Chrysler Neon* passenger car on a single-node platform with 4 sockets/60 cores/120 threads and 256 GB of memory. RADIOSS was able to easily take advantage of all 60 cores, running the workload 2.75X faster ...

The purpose of this paper is to evaluate different formulas which are used to estimate the motorcycle’s pre-collision speed in motorcycle-to-car accidents. These formulas are based on measurable physical parameters such as motorcycle’ wheelbase change and fundamental physical laws such as conservation of momentum. The evaluation used data from crash experiments performed by the authors as well ...

In this paper, an automatic pre–crash collision avoidance strategy for cars is presented. It produces a collision avoidance manoeuvre, if feasible, or, otherwise, an emergency braking to reduce the energy at the impact. The manoeuvre is generated relying on the use of sliding mode control. The performances of the proposed collision avoidance system are tested on a scaled radio–controlled car an...

A finite element (FE) model of a 1998 Audi Model A8 has been developed for the crash analysis associated with the NHTSA NCAP program. The AUDI model A8 is an all aluminum four-door passenger vehicle; it is classified as a ‘large sedan’ car. The model developed is to be used to analyze frontal impact against a rigid barrier as specified in standard procedures associated with the assessment of pa...

General George S. Patton Jr. died as the result of quadriplegia sustained in a car crash in Germany in 1945. His x-ray films revealed a fractured C-3 vertebra and a posterior dislocation of C-4 on C-5. The likely cause of death was a pulmonary embolus. Details of his medical treatment are reviewed and compared with therapies that a patient with a similar injury would receive today.

Motor vehicle crashes are the leading cause of death and acquired disability in children over age 1 in the United States. In 1998 alone, 697 children under age 6 died as occupants in motor vehicles, and nearly 100,000 were injured. This Issue Brief describes findings from Partners for Child Passenger Safety, the nation's largest surveillance system of children in car crashes, and points to impr...

Simultaneous bilateral intertrochanteric fractures are very rare, and only a few cases have been reported in the literature. They usually result from severe trauma. They are serious injuries with high morbidity and mortality rates. Successful management of these patients involves adequate resuscitation, treatment of associated injuries, early single-stage stable fixation, and good rehabilitatio...

1 I n t r o d u c t i o n Safety measures like airbags and safety belts are nowadays commonly applied to improve the crash worthiness of road vehicles. Many governments stimulate or oblige by law car producers to include these devices in the vehicle design. Maximum values are imposed on parameters that quantitatively describe the severity of injuries. Examples are the Head Injury Criterion (HIC...
