The Aurora and Borealis Stream Processing Engines
Over the last several years, a great deal of progress has been made in the area of stream-processing engines (SPEs) [9, 11, 17]. Three basic tenets distinguish SPEs from current data processing engines. First, they must support primitives for streaming applications. Unlike Online Transaction Processing (OLTP), which processes messages in isolation, streaming applications entail time series oper...
متن کاملAurora borealis wraps Plk1 and CDK together
Proper execution of mitosis requires the phosphorylation of hundreds of functional proteins by multiple protein kinases. Activation and inactivation of these kinases needs to be coordinated so that the correct order and timing of mitotic events allows faithful chromosome inheritance. The intrinsic oscillation of one of these kinases, the cyclin-dependent kinase (CDK), has been shown to be compo...
متن کاملAurora Borealis: Stochastic Cellular Automata Simulations of the Excited-State Dynamics of Oxygen Atoms
Emissions from the 1S and 1D excited states of atomic oxygen play a Ž . prominent role in creating the dramatic light displays aurora borealis seen in the skies over polar regions of the Northern Hemisphere. A probabilistic asynchronous cellular w automaton model described previously Seybold, Kier, and Cheng, J Phys Chem 1998, x 102, 886]891 has been applied to the excited-state dynamics of ato...
متن کاملSlicing the Aurora
We have generated large-scale digital prints from a sequence of photographs of the northern sky taken over the course of one night. Each image is aggregated across time creating visually appealing and intriguing images – or Keograms – that visualize Aurora Borealis (Northern Lights) activity as well as interesting movements of clouds and stars that occurred that night.
متن کاملSimulating the aurora
We present the first computer graphics algorithm designed to simulate the aurora, a natural phenomenon of great visual beauty and considerable scientific interest. The algorithm is based on the current understanding of the physical origin of this natural display. The aurorae are mainly caused by high-energy electrons originating in the sun and entering the earth’s atmosphere in narrow regions c...
