A novel approach to the automatic detection of fault surface images in 3D seismic datasets is presented. Based on the premise that seismic faulting introduces discontinuities into the rock layering (that is, the horizons), a coherency measure is used to detect points of significant horizon discontinuity. A highest confidence first (HCF) merging strategy is then combined with a flexible surface ...

Incarprating with $he frequency measure, a ncural network impkmearP;tion of the K-means algsrithni is then proposed to identify clusters of c...

The imaginary part of coherency is a measure to investigate the synchronization of brain sources on the EEG/MEG sensor level, robust to artifacts of volume conduction meaning that independent sources cannot generate a significant result. It does not mean, however, that volume conduction is irrelevant when true interactions are present. Here, we analyze in detail the possibilities to construct m...

A major factor in determining the effectiveness of caching in wireless networks is the cache coherency scheme which maintains consistency between mobile stations (MSs) and the server. Since the wireless channel is inherently a broadcast medium, an appropriate cache coherency scheme is one in which the server broadcasts cache invalidation reports (IRs) that contain data update information. Howev...

Recently there has been considerable interest in cache coherency protocols in shared-memory multiprocessor systems, particularly in protocols which are scalable, i.e. suitable for very large systems. However, cache coherency scalability (CCS) entails heavy performance overhead and system cost, so a critical examination of the assumptions underlying the quest for CCS is undertaken here. A non-CC...

Why this method is Important The Coherency Architect should consider the case study method an important tool since the Architect has to investigate the organization or organizations they work with to investigate and uncover problems that needs to be solved before the organization can continue with it plans to achieve its goals. The Case Study Method gives the Coherency Architect tools which can...

Introduction Traditionally, the analysis of seismic data involved looking for continuous events on seismic data, from which structural and stratigraphic features could be mapped. However, we are also interested in mapping discontinuous features such as faults and fractures. A method for identifying these discontinuities was first introduced by Bahorich and Farmer (1995) and called the coherency...

Structural models with no solution are incoherent, and those multiple solutions incomplete. We show that occasionally binding constraints not generically coherent. Coherency requires restrictions on the parameters or support of distribution shocks. In presence shocks, cannot be independent from each other, so assumption orthogonality structural shocks is incompatible coherency. Models whose coh...

Prolonged observations of moving plaids lead to bi-stable alternations between coherency and transparency. However, most studies of plaids used brief presentations and a 2AFC between the two interpretations, thus overlooking the dynamical aspect of plaid perception. In other domains, most notably binocular rivalry, it was shown that the dynamics of the bi-stable alternations reveal important in...
