Continuous Queries Over Eddies
We present a continuous query system built on top of Eddies, a query-processing engine which replaces static query plans with per-tuple dynamic routing decisions. We discuss why this implementation is superior to traditional continuous query schemes, and present encouraging initial performance results which demonstrate the scalability and efficiency of our system.
متن کاملCurrents and Eddies in Practice
When one passed as a student from Arts to Medicine, and back again to Arts-as some of us did-Professor Boas with his Shakespearean recollection of the witches would refer to our "fitful reappearances ." In making one of these, I invite you to come down from the bright circle where you have sojourned at the last few meetings, and have a peep at the pit-even though. in the modern theatre there ma...
متن کاملLoop Current and Deep Eddies
In contrast to the Loop Current and rings, much less is known about deep eddies (deeper than 1000 m) of the Gulf of Mexico. In this paper, results from a high-resolution numerical model of the Gulf are analyzed to explain their origin and how they excite topographic Rossby waves (TRWs) that disperse energy to the northern slopes of the Gulf. It is shown that north of Campeche Bank is a fertile ...

متن کاملAnticyclonic eddies are more productive than cyclonic eddies in subtropical gyres because of winter mixing
Mesoscale eddies are ubiquitous features of ocean circulation that modulate the supply of nutrients to the upper sunlit ocean, influencing the rates of carbon fixation and export. The popular eddy-pumping paradigm implies that nutrient fluxes are enhanced in cyclonic eddies because of upwelling inside the eddy, leading to higher phytoplankton production. We show that this view does not hold for...
