The coherency index

Conversational Coherency

A major goal of this work is to specify some steps of the process by which participants maintain coherency in their conversations. The underlying element of the analysis is a construct called a 'context space'. Roughly, a group of utterances that refers to a single issue or episode forms the basis for a context space. Superficially a conversation is a sequence of utterances; at a deeper level i...

Optical coherency matrix tomography

The coherence of an optical beam having multiple degrees of freedom (DoFs) is described by a coherency matrix G spanning these DoFs. This optical coherency matrix has not been measured in its entirety to date--even in the simplest case of two binary DoFs where G is a 4 × 4 matrix. We establish a methodical yet versatile approach--optical coherency matrix tomography--for reconstructing G that ex...

Coherency Maximizing Exploration in the Supermarket 1

In uncertain environments, effective decision makers balance exploiting options that are 8 currently preferred against exploring alternative options that may prove superior 1,2. For 9 example, a honeybee foraging for nectar must decide whether to continue exploiting the 10 current patch or move to a new location 3-6. When the relative reward of options changes over 11 time, humans explore in a ...

Free Will and Rational Coherency

Coherency in Distributed Shared Memory

We present a new model for distributed shared memory systems, based on remote data accesses. Such features are offered by network interface cards that allow one-sided operations, remote direct memory access and OS bypass. This model leads to new interpretations of distributed algorithms allowing us to propose an innovative detection technique of race conditions only based on logical clocks. Ind...
