Autonomously detecting and recovering from faults is one approach for reducing the operational complexity and costs associated with managing computing environments. We present a novel methodology for autonomously generating investigation leads that help identify systems faults, and extends our previous work in this area by leveraging Restricted Boltzmann Machines (RBMs) and contrastive divergen...

Precise factors controlling the coevolution of deformation and topography in tectonically active landscapes remain poorly understood due to complex feedbacks between numerous possible variables. Here we examine the links between fault kinematics, emergent topography, and environmental factors on a global data set of active fault-driven mountain ranges (n = 41). Using simple regressions between ...

In this chapter, we review the state of the art and practice in fault-based testing. Based on the analysis and the reviews, we propose a comprehensive method for testing and present its main elements. Traditional fault-based testing is concerned with syntactic errors. These errors represent only a small portion of possible errors. Our testing approach is not restricted to these errors. We propo...

This is the second paper of two, which describe the results of an integrated research effort to develop a four–step simplifi ed approach for design of raft foundations against dip-slip (normal and thrust) fault rupture. The fi rst two steps dealing with fault rupture propagation in the free-fi eld were presented in the companion paper. This paper develops an approximate analytical method to ana...

The present research studies the motion of a particle or a spacecraft that comes from an orbit around the Sun, which can be elliptic or hyperbolic, and that makes a passage close enough to the Earth such that it crosses its atmosphere. The idea is to measure the Sun-particle two-body energy before and after this passage in order to verify its variation as a function of the periapsis distance, a...

k-Restricted edge connectivity is an important parameter in measuring the reliability and fault tolerance of large interconnection networks. In this paper we present two families of graphs similar with the networks proposed by Chen et al. [Y.C. Chen, J.J.M. Tan, L.H. Hsu, S.S. Kao, Super-connectivity and super edge-connectivity for some interconnection networks, Applied Mathematics and Computat...

This special issue of Natural Hazards and Earth System Sciences (NHESS) contains 16 papers that resulted from the European Science Foundation (ESF) Research Conference “Submarine Paleoseismology: The Offshore Search of Large Holocene Earthquakes” that was held at the Universitätszentrum Obergurgl (Austria), from 11 to 16 September 2010 (Pantosti et al., 2011). The conference enabled scientists ...

[1] Several lines of evidence, including remote triggering of earthquakes and modulation of seismic tremor by Earth tides, suggest that faults weakenwhen subject to shaking and dynamic stresses associatedwith the passage of seismic waves. However, the origin of such dynamic weakening is poorly understood. Here we explore the role of acoustic resonance for dynamic fault weakening using laborator...

The three-body problem is a powerful tool for understanding non-Keplerian orbits. This project focuses on the Circularly Restricted Three-Body Problem (CRTBP), which can be applied to the Sun-Earth and Earth-Moon systems. In particular, we are interested in the Lagrange points of both systems and the Halo orbits that exist about them. These orbits are important for scientific missions, space st...
