This research presents the geotechnical zoning map of district 1 in Shiraz municipality with focus on municipal deep excavation hazard assessment on data from 160 boreholes. For this purpose, the mechanical properties are determined according to the results of direct shear, uniaxial, and SPT tests and then excavation hazard assessment with depths of 3, 6 and 9 m, in situations where the excavat...

Multilevel Logic Optimization Transformations used in existing logic synthesis systems are characterized with respect to their testability preserving and testability enhancing properties. A su cient condition for a multilevel unate circuit to be \hazard free delay fault testable" is presented. In contrast to existing results that consider either \single path propagating hazard free robust tests...

Hazard perception is a critical skill for road users. In this study, an open-loop motorcycle simulator was used to examine the effects of motorcycle riding and car driving experience on hazard perception and visual scanning patterns. Three groups of participants were tested: experienced motorcycle riders who were experienced drivers (EM-ED), inexperienced riders/experienced drivers (IM-ED), and...
