In the narrow geosynthetic-reinforced retaining walls a stable rear wall exists in a short distance and so there is no enough space to extend appropriate length of reinforcements. In this case, the probability of overturning of retaining wall increases especially when subjected to earthquake loading. To increase the stability of the wall, reinforcements may be connected to the stable rear surfa...

INTRODUCTION Intelligent vehicles become to gather more and more interest and are drastically progressing (Bishop, 2005). Until recent days, respective system functions have been developed such as LDW(Lane Departure Warning), ACC(Adaptive Cruise Control), CW/CA(Collision Warning/Collision Avoidance), IPAS(Intelligent Parking Assist) and BSD(Blind Spot Detection).

This technical note describes a time-saving device for aligning the rear wheels of a racing wheelchair. The newly-developed analog alignment device is compared to the now standard discrete alignment device. The analog alignment device is found to reduce the time needed to align the rear wheels by nearly 75 percent, while increasing the accuracy of the alignment. The device does not noticeably a...
