A Trigger Mechanism for Loop Current Ring Separations

A Trigger Counting Mechanism for Ring Topology

Consider a distributed system with n processors, which receive triggers from the outside world. The Distributed Trigger Counting (DTC) problem is to raise an alarm if the number of triggers over the system reaches w, which is an user specified input. DTC is used as a primitive operation in many applications, such as distributed monitoring, global snapshot etc. In this paper, we propose an algor...

Frequency of Ring Separations from the Loop Current in the Gulf of Mexico: A Revised Estimate

The most energetic events in the circulation of the Gulf of Mexico are the separation of large anticyclonic rings from the Loop Current. Building on previous work, the authors examine all the apparent rings since July 1973. This new dataset includes the satellite altimetry since 1992, providing a set of 34 consecutive ring formations. The primary advantage of altimetry is that the data remain a...

A Current Disruption Mechanism in the Neutral Sheet: a Possible Trigger for Substorm Expansions

A linear analysis is performed to investigate he kinetic ross-field streaming instability in the Earth's magnetotail neutral sheet region. Numerical solution of the dispersion equation shows that the instability can occur under conditions expected for the neutral sheet just prior to the onset of substorm expansion. The excited waves are obliquely propagating whistlers with a mixed polarization ...

A Novel Data Compression Technique for 420 Ma Current Loop Transmitters

This paper presents a new data compression method for current loop transmitters. In this method, the 4-20 mA current domain is divided into some equal pieces that are used for distinct data domain with a constant relative resolution, resulting in widening the signal span. This technique eliminated the need for high resolution ADC’s or DAC’s in communication of 4-20mA current loop signals. Furth...
