In this paper, we de ne a measure for evaluating conversational coherency and propose a method of computing it. We de ne a deliberation stream in email communication and construct deliberation structure which the deliberation streams are introduced into. And we de ne discontinuity between utterances as the measure for evaluating conversational coherency by using the deliberation structure, con ...

To first order, seismic data provides the geologist and the geophysicist with information on the geometrical relationships between subsurface lithologic boundaries. Generally, this spatial information is used to construct conceptual geologic and process models with which to explain the origins of stratigraphic features. From such models we infer lithologic content. Various methods (e.g. AVO, Co...

This paper introduces GAVIP, an interactive and immersive platform allowing for audio-visual virtual objects to be controlled in real-time by physical gestures and with a high degree of intermodal coherency. The focus is particularly put on two scenarios exploring the interaction between a user and the audio, visual, and spatial synthesis of a virtual world. This platform can be seen as an exte...

One of the key challenges in chip multi-processing is to provide a programming model that manages cache coherency in a transparent and efficient way. A large number of applications designed for embedded systems are known to read and write data following memory access patterns. Memory access patterns can be used to optimize cache consistency by prefetching data and reducing the number of memory ...

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...

This contribution presents a stochastic analysis model, aiming at segmentation of the motion vector fields from compressed video sequences into regions of coherent motion. We propose a stochastic motion coherency model based on parametric affine motion. This model applies the 2-D GibbsMarkov random field to identify motion-coherent smoothcontour regions and corresponding motion model estimates....

Anew, fully conservedminimal adjustment schemewith temperature and salinity (T,S) coherency is presented for eliminating false static instability generated from analyzing and assimilating stable ocean (T, S) profiles data, that is, from generalized averaging over purely observed data (data analysis) or over modeled/observed data (data assimilation). This approach consists of a variational metho...

JUMP-1 is currently under development by seven Japanese universities to establish techniques of an e cient distributed shared memory on a massively parallel processor. It provides a memory coherency control scheme called the hierarchical bit-map directory to achieve cost e ective and high performance management of the cache memory. Messages for maintaining cache coherency are transferred throug...

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...
