Day By Day

Fatal accidents are increasing day-by-day due to the failure of wheel bearing, unbalancing of wheel and tyre bursting due to increase in the temperature. Bearing is the most important mechanical device on which the wheel performance of a vehicle depends. Lack of proper periodic maintenance of the bearing leads to the failure of bearing, which results in wheel misalignment. Hence, tyres with wheels come out from the axial in moving condition, which results in accidents. Bearing failure can also be due to bearing buckling, scratches, nicks, discoloration, corrosion and crack. This can be due to lack of lubrication or overheating etc. Also due to improper tyre pressure, harsh braking and increase in the temperature of the tyre, tyre gets heated up causing tyre bursting which leads to fatal accidents. The main objective is to detect tyre temperature and wheel alignment deviation, thereby providing indication through audio-visual system which prevents accidents of the vehicle and the driver from an injury or death. Hence, we have used ARDUINO UNO, ULTRASONIC SENSOR, LEDS, DHT11 SENSOR and BUZZER.

The Mean

Abstract Lower and upper bounds of the peak horizontal ground acceleration are obtained through the consideration of the peak accelerations of two horizontal orthogonal components of the ground motion. Since the bounded region is relatively narrow, it is proposed to use the mean of the upper and lower bound accelerations as the peak horizontal ground acceleration. This mean value is equal to 1.20 times the larger peak acceleration of the two horizontal components of the ground motion. To support the proposed value, a simplified statistical analysis is also employed which results in a mean plus one standard deviation value for the peak horizontal ground acceleration of 1.24 times the larger peak acceleration. These conclusions are also supported by comparison with 50 pairs of earthquake acceleration records. For the resultant acceleration, the 50 pairs of records yield a mean plus one standard deviation estimate of the order of 1.20 times the larger peak acceleration.
