The great Indian invisible railroad disaster.
doi:10.1017/S1049023X12000544 As traffic accidents occupy center stage in injury discussions, Forsberg and colleagues’ report ‘‘One hundred years of railway disasters and recent trends’’ made interesting reading. With trains traveling at higher and higher speeds, the authors correctly recommend injury prevention and safety mechanisms to decrease the risk of mass-casualty events. The robust Emer...
متن کاملTrespassing on the Railroad
Greater than half of all the fatal injuries on United States railroads are sustained by trespassers. The paper provides a statistical analysis of the demographics of trespassers, the activities they were engaged in, and the causes of injury. It also analyzes trends over time. The paper finds that the risks of injury and death are particularly acute for males in their 20s and 30s. The annual cas...
متن کاملRAID-CUBE: The Modern Datacenter Case for RAID
“Big Data” processing in modern datacenters dramatically increases the data volume moving between applications and storage. A major challenge is achieving acceptable levels of availability and reliability in an environment characterized by huge storage capacities, large numbers of disk drives, and very high interconnection bandwidth (e.g., 100 petabytes and 17000 disk drives at CERN1). In this ...
متن کاملSwift/RAID: A Distributed RAID System
The Swift VO architecture is designed to provide high data rates in support of multimedia type applications in general-purpose distributed environments through the use of distributed striping. Strþing techniques place sections of a single logical data space onto multiple physical devices. The original Swift prototype was designed to validate the architecture, but did not provide fault tolerance...
متن کاملDon't Let RAID Raid the Lifetime of Your SSD Array
Parity protection at system level is typically employed to compose reliable storage systems. However, careful consideration is required when SSD based systems employ parity protection. First, additional writes are required for parity updates. Second, parity consumes space on the device, which results in write amplification from less efficient garbage collection at higher space utilization. This...
