  Fat can indeed act as a shock absorber in violent collision. A 2003 study of car-crash victims found that those with more fat were less likely to suffer abdominal injuries. But the fat-as-airbag principle only goes so far. When a driver is flung forward, the heavier his or her body, the greater the force required to stop it.

  The pelvis is the primary load-bearing structure for scat-belt safety, Kent, an American scientist, says. But with big stomachs, seat belts slide up and off the lap. Since a restraint works best once it engages with a dead body, any time it spends pressing into soft tissue will delay that protective effect.

   To observe this, Kent defrosted eight dead bodies and belted them into car seats for a 30mph crash. High-speed video showed that the obese bodies flew off their seats pelvis-and lower-chest first. Smaller subjects’ hips stayed in place as their heads and the main body thrown against the upper strap. That may help explain the pattern of injuries typically seen in obese crash victims—more damage to the legs, less to the head, and a greater likelihood of death.

  Computer vision is the science and technology of machines that see. As a scientific discipline, computer vision is concerned (31)the theory and technology for building artificial systems that obtain information from images(32)multi-dimensional data. A significant part of (33) intelligence deals with planning or deliberation for system which can perform (34)actions such as moving a robot (35) some environment. This type of processing typically needs input data provided (36) a computer vision system, (37) as a vision sensor and (38)high-level information about the environment and the robot. Other parts which sometimes are described as(39) to artificial intelligence and which are used in relation to computer vision are pattern (40) and learning techniques.

In the adult study, a series of factors were significantly associated with the perception of car fumes or dust/soot. Annoyance due to noise exposure and rated impairment of life quality showed the stronger association in the logistic models. But odor and noise sensitivity also had a significant impact on the ratings.
