We study a market in which both buyers and sellers can decide to preempt and set their quantities before market clearing. Will this lead to preemption on both sides of the market, only one side of the market, or to no preemption at all? We find that preemption tends to be asymmetric in the sense that it is restricted to only one side of the market (buyers or sellers). D 2006 Elsevier B.V. All r...

Most multiprocessors are multiprogrammed in order to achieve acceptable response time and to increase utilization. Unfortunately, inopportune preemption may significantly degrade the performance of synchronized parallel applications. To address this problem, researchers have developed two principal strategies for concurrent, atomic update of shared data structures: preemption-safe locking and n...

This study reports on a case study examining the impact of emergency vehicle preemption on closely spaced arterial traffic signals. The study was conducted on SR 26 a principal arterial and main thoroughfare connecting Interstate 65 with US 52 on the East side of Lafayette, Indiana. This study examined four coordinated intersections along SR 26 using seven preemption paths and three different t...
