System redundancy in aircraft is very important as it ensures faulty components would not jeopardize the safety of crew and passengers. High priority system such as flight control computers, instruments system and controller for control surface mechanism have double or triple redundancy to maintain the aircraft safety. While full scale aircraft has multiple redundancy system installed, small un...

Multi-protocol Label Switching (MPLS) has become an attractive technology of choice for Internet backbone service providers. MPLS recovery mechanisms are increasing in popularity because they can guarantee fast restoration and high QoS assurance. To provide dependable services MPLS networks make use of a set of procedures (detection, notification and fault recovery) which seek to ensure appropr...

In a grid environment there are thousands of resources, services and applications that need to interact in order to make possible the use of the grid [1] as an execution platform. Since these elements are extremely heterogeneous, volatile and dynamic, there are many failure possibilities, including not only independent failures of each element, but also those resulting from interactions between...

Fault tolerance is an important feature for the system LSIs used in reliability-critical systems. Although redundancy techniques are generally used to provide fault tolerance, these techniques have significantly hardware costs. However, FPGAs can easily provide high reliability due to their reconfiguration ability. Even if faults occur, the implemented circuit can perform correctly by reconfigu...

Self–repairing digital systems have received increased attention as the modern systems are becoming more complex and fast. For systems operating in harsh and/or hostile environments even a single failure event can result in huge loss and disastrous effects. Availability of a system can be increased by making it capable of detecting and recovering from faults, i.e. make it fault tolerant. In thi...

The inherent redundancy and in-the-field reconfiguration capabilities of field programmable gate arrays (FPGAs) provide alternatives to integrated circuit redundancy-based fault recovery techniques. An algorithm for efficient runtime recovery from permanent logic faults in the Xilinx 4000 architecture has been expanded to include interconnect fault recovery and has been applied to a diverse set...

Resource provisioning remains as one of the challenging research problems in cloud computing, more importantly when considered together with service reliability. Fault-tolerance techniques such as fault-recovery is one of the techniques that can be employed to improve on service reliability. Technically, fault-recovery has obvious impact on service performance. Such impact requires detailed stu...

Many “big data” applications need to act on data arriving in real time. However, current programming models for distributed stream processing are relatively low-level, often leaving the user to worry about consistency of state across the system and fault recovery. Furthermore, the models that provide fault recovery do so in an expensive manner, requiring either hot replication or long recovery ...

OBJECTIVES To establish the association between the patient's perception of fault for the crash and 12-month outcomes after non-fatal road traffic injury. SETTING Two adult major trauma centres, one regional trauma centre and one metropolitan trauma centre in Victoria, Australia. PARTICIPANTS 2605 adult, orthopaedic trauma patients covered by the state's no-fault third party insurer for roa...
