Explosions near Isolated Unstable Attractors

We describe the set of explosive orbits in the region of attraction of an unstable attractor which is isolated in the sense of C.C. Conley. Sufficient conditions are given for the existence of explosions in certain parts of the region of attraction and for an unstable attractor to have finitely generated integral Alexander-Spanier cohomology groups. Finally, we study the case of singularities t...

Acoustic Reflectometry for Gas Pipelines – Monitoring Features in Gas Pipelines Using Acoustek

This paper will provide an overview of a patented acoustic technique known as Acoustek ® that has been developed to detect features, such as blockages and leakages in gas pipelines. The technique involves injecting an acoustic, or pressure pulse into the gas within the pipeline. This acoustic pulse will travel as a plane wave along the pipeline and will be partially reflected wherever there is ...

Using Operating Data at Natural Gas Pipelines

INTRODUCTION Interstate natural gas pipelines are operated using sophisticated supervisory control and data acquisition (SCADA) systems. These systems are used to monitor, control and analyze operations. Software which runs in conjunction with the basic SCADA system expands the usefulness of SCADA data to enhance reliability and efficiency of operations, improve customer service, and minimize u...
