Fault-crossing tunnels are often severely damaged under seismic dynamics. Study of the dynamic response characteristics crossing faults is thus great engineering significance. Here, Xianglushan Tunnel Central Yunnan Water Diversion Project was studied. A shaking table experimental device used, and four sets model tests deep-buried with different fault inclination angles were conducted. Test sch...

OBJECTIVES To evaluate the relationship between performance-based risk factors and subsequent at-fault motor vehicle collision (MVC) involvement in a cohort of older drivers. DESIGN Prospective cohort study. SETTING Motor Vehicle Administration (MVA) field sites in Maryland. PARTICIPANTS Of the 4,173 older drivers invited to participate in the study, 2,114 individuals aged 55 to 96 agreed...

OBJECTIVES To examine the relationship between frequent falls in older drivers and motor vehicle collision (MVC) involvement. DESIGN Cross-sectional. SETTING North central Alabama. PARTICIPANTS Population-based sample of 2,000 licensed drivers aged 70 and older. MEASUREMENTS Self-reported history of falling two or more times in the prior year was the main predictor. Outcomes were any MV...

One of the most destructive historical earthquakes (M 6.7) in Spain occurred in 1884 along the normal Ventas de Zafarraya Fault located in the Central Betic Cordilleras. Palaeoseismic and radiocarbon data presented in this study are the first to constrain the timing of the pre-1884 fault history in the last 10 ka. These data yield a recurrence interval of between 2 and 3 ka for major earthquake...

A common type of program fault is related to branch statements, which is referred to as branch fault. In an object-oriented (OO) programming paradigm, branch statements are typically used to implement state-dependent behavior of classes or clusters of classes. Thus, one effective way to locate the branch fault in an OO program is to identify a condition on the object or object cluster state tha...

Byzantine fault-tolerant (BFT) replication has enjoyed a series of performance improvements, but remains costly due to its replicated work. We eliminate this cost for read-mostly workloads through Prophecy, a system that interposes itself between clients and any replicated service. At Prophecy’s core is a trusted sketcher component, designed to extend the semi-trusted load balancer that mediate...

That faults are of fundamental importance in petroleum systems cannot be stressed enough. The role the faults play, however, is complicated by their dual nature as fluid seals and conduits. Understanding a fault’s behavior demands extensive knowledge of its past geologic history, core samples, pressure measurements, and well logs. Further complicating matters, the sealing capacity of a fault us...
