Current trends in device scaling continue to cause an increasing risk of transient faults in microprocessors due to high energy strikes from radiated particles. In this work, we present a thorough microarchitectural analysis of the effects of soft errors on a production-level Verilog implementation of an ARM926EJ-S core. We examine the propagation of faults occurring in both sequential state el...

Widespread use of non-volatile memories, especially flash memories, in diverse applications such as in mobile computing and systemon-chip is becoming a common place. As a result, testing them for faults and reliability is drawing considerable interest of designers and researchers. One of the most predominant failure modes for which these memories must be tested is called disturb faults. In this...

In this paper, an approach for suitable fault management in traffic information networks, focusing on the isolation of network faults in infrastructure networks, will be introduced. We will show, that modelbased diagnosis is an efficient method for finding explanations consisting of the underlying fault events of system failures. A fault management system based on these concepts will be discuss...

SRAM based FPGAs are attracting considerable interest especially in aerospace applications due to their high reconfigurability, low cost and availability. However, these devices are strongly susceptible to space radiation effects which are able to cause unwanted single event upsets (SEUs) in the configuration memory. In order to mitigate the SEU effects, various methods have been investigated i...

The paper presents a probabilistic fault arc reignition model for MV distribution networks. The model has been developed and implemented in the EMTP program, in order to evaluate the possible benefits of enlarging the time delay before the first fast reclosure, in terms of reducing the probability of fault reignition and, thus, avoiding longer interruptions. The application of the model in simu...

Smart environment applications demand novel solutions for managing quality of services, especially availability and reliability at run-time. The underlying systems are changing dynamically due to addition and removal of system components, changing execution environments, and resources depletion. Therefore, in such dynamic systems, the functionality and the performance of smart environment appli...

Abstract: Since incipient faults often have small amplitudes and obscure symptoms, those observer-based or output residual-based fault indicators are ineffective for incipient faults, especially in the presence of system disturbances. The ToMFIR-based fault detection approaches use both controller and output residuals to construct a fault indicator, which make them sensitive to incipient faults...

The sealing of a fault zone has been focus for geological studies in the past decades. majority previous have focused on extensional regimes, where displacement pressure difference between rock and reservoir was used to evaluate fault-sealing property from basic principle sealing. When considering difference, impact gravity considered, whereas horizontal stress ignored. In this study, we utiliz...

Quantifying fault damage zones provides a window into stress distribution and rheology around faults. International Ocean Discovery Program (IODP) Expeditions 372/375 drilled an active thrust splay within the Hikurangi subduction margin. The fault, which is hosted in Pleistocene clastic sediments, surrounded by brittle fractures faults as well ductile deformation features. We find that fracture...

The month of May 2015 marked the sixth year since the end of conflict in Sri Lanka. The cause of death, destruction and displacement, three decades of conflict has had a major impact on health, especially on mental health of those affected by forced displacement. Post-conflict regions of Sri Lanka has seen improvements in many areas, including resettlement of displaced populations and rebuildin...
