Live Concert Performance: An Ecological Approach

The CyberWhistle - An Instrument For Live Performance

The CyberWhistle is an integrated approach to a new electronic instrument, with emphasis given to aesthetic and practical considerations. It consists of a penny whistle1 fitted with sensors and electronics connected by cable to a desktop computer, a Silicon Graphics Indy. In contrast to many windcontrollers, the continuous position of the fingers is sensed. Audio is produced on multiple channel...

A Versioning Approach to VM Live Migration

In the context of virtual machines live migration, two strategies called “pre-copy” and “post-copy” have already been presented; but each of these strategies works well only in some circumstances. In this paper, we have a brief presentation of QAVNS and then introduce a new approach which is based on the concept of "informational object", assigning QAVNS-scheme-revision number, and observing th...

An Ecological Approach to Cognitive Science{1}

[1] Cognitive science is ready for a major reconceptualization.(1) This is not at all because efforts by its practitioners have failed, but rather because so much progress has been made. The need for reconceptualization arises from the fact that this progress has come at greater cost than necessary, largely because of more or less philosophical (at least metatheoretical) straightjackets still w...

GIS Technology Transfer : An Ecological Approach

An Ecological Approach to Agent Population Management

The problem of maintaining a desired number of mobile agents on a network is not trivial, especially if what is required is a completely decentralized solution. Decentralized control makes a system more robust and less susceptible to partial failures. The problem of agent population management is exacerbated on wireless ad hoc networks where host mobility can result in significant changes in th...
