We present a general method for calculating the stacking-fault energy in simple metals, and then we apply this to the ( 1 1 2 ) faults in body-centred cubic (BCC) metals. Our method contains no approximations for a given wavenumber characteristic (or equivalently the pair potential). Our results show that metastable faults do indeed exist in the simple BCC metals (Li, Na. K, Rb, Cs, Ca. Sr, Ba)...

Real-time control applications involve the interaction of multiple components. As systems become more complex their reliability tends to decrease, hence, fault tolerance must be incorporated to keep reliability within specified levels. A reconfiguration mechanism for processor arrays inspired by mechanisms that take place during the embryonic development of living beings is proposed in this pap...

Seismic anisotropy and P-wave delays in New Zealand imply widespread deformation in the underlying mantle, not slip on a narrow fault zone, which is characteristic of plate boundaries in oceanic regions. Large magnitudes of shear-wave splitting and orientations of fast polarization parallel to the Alpine fault show that pervasive simple shear of the mantle lithosphere has accommodated the cumul...

The possibility of failure is a fundamental characteristic of distributed applications. The research community in fault tolerance has developed several solutions mainly based on the concept of replication. In this paper, we propose a fault tolerant hybrid approach in multi-agent systems. We have based our strategy on two main concepts: replication and teamwork. Through this work, we have to cal...

The unexpected weakness of some faults has been attributed to the emergence of acoustic waves that promote failure by reducing the confining pressure through a mechanism known as acoustic fluidization, also proposed to explain earthquake remote triggering. Here we validate this mechanism via the numerical investigation of a granular fault model system. We find that the stick-slip dynamics is af...

Offset geomorphic features along the Superstition Hills fault show evidence for at least one slip event prior to the 1987 surface rupture, and possibly as many as four to five earlier prehistoric earthquakes. We documented several geomorphic features that appeared offset by multiple events by making detailed topographic maps. Offset features were abundant along reaches of the fault with high to...
