An Introduction to Software Engineering and Fault Tolerance [PDF]

open access: yesIntroduction chapter to the "SOFTWARE ENGINEERING OF FAULT TOLERANT SYSTEMS" book, Series on Software Engineering and Knowledge Eng., 2007, 2010
This book consists of the chapters describing novel approaches to integrating fault tolerance into software development process. They cover a wide range of topics focusing on fault tolerance during the different phases of the software development, software engineering techniques for verification and validation of fault tolerance means, and languages ...

In situ loading of a pore network model for quantitative characterization and visualization of gas seepage in coal rocks

open access: yesDeep Underground Science and Engineering, EarlyView.
Fine modeling of a three‐dimensional fracture structure under dynamic loading of coal is carried out. The streamline distribution law of pressure and velocity field in the loading process of the coal specimen is analyzed, the absolute permeability of the coal specimen is calculated, and the feasibility of the pore network model algorithm and finite ...

Structural pattern and its control on hydrocarbon accumulations in Wushi Sag, Kuche Depression, Tarim Basin

open access: yesPetroleum Exploration and Development, 2008
Affected by the South Tianshan orogenesis, the faulted structure patterns in the Wushi Sag are very complex. Aimed to find out the basic characteristics of the structures, this article studies many seismic profile sections, the regional geology, the ...

An analytical solution of direction evolution of crack growth during progressive failure in brittle rocks

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel analytical method is proposed to evaluate the shear stress effect on the progressive compressive failure and microcrack growth direction in brittle rocks. The shear stress effect on the wing crack growth direction during the progressive compressive failure is determined. The initial crack angle effect on the y‐direction peak stress and the wing

Closely piling up of multiple adhesive fronts in adhesive friction due to re-attachment [PDF]

open access: yesarXiv
As a fundamental force, friction exerts a profound influence on various aspects of our daily lives across multiple disciplines. To understand why adhesive friction is associated with the contact area, here we investigate the generic sliding of elastic solids adhered to a rigid surface by considering re-attachment/healing.

A review of multiscale numerical modeling of rock mechanics and rock engineering

open access: yesDeep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Structural heterogeneity and permeability in faulted eolian sandstone: Implications for subsurface modeling of faults [PDF]

open access: yes, 2002
We determined the structure and permeability variations of a 4 km-long normal fault by integrating surface mapping with data from five boreholes drilled through the fault (borehole to tens of meters scale).

Paraxial micro earthquake: a natural effective multi-purpose check shot for downhole earthquake monitoring [PDF]

open access: yesarXiv
Downhole earthquake monitoring, without the effects from the overburden, can record better seismic data than monitoring on surface. However, in order to reasonably use the downhole vector seismic data, a constant challenge is how to accurately orient the downhole radial-component seismometers.
