Camera that takes pictures of aircraft and ground vehicle tires can save lives
Damaged tires cause many fatal car accidents that claim lives worldwide. The use of a regular digital camera that can generate JPEG images, so as to become aware of damaged tires, is proposed. The digital camera repeatedly takes pictures of the car’s tires. When there is a drastic change in a particular block of JPEG, the value of many of its frequency coefficients will be high and it will be c...

متن کاملTires Back into Tires: Devulcanization of Tire Rubbers
The optimal process conditions for a high ratio of de-vulcanization to polymer degradation have been elaborated for tire rubbers: SBR, BR, NR and CIIR. These polymers all show their own particular breakdown characteristics, and the temperature dependence of the breakdown mechanism was investigated by measuring sol fractions and crosslink densities. For SBR and BR, the highest reduction in cross...
