Cayuga User Manual
1.1. Roadmap. Section 2 introduces the directory structure of the code base, as well as the third-party libraries used by Cayuga. Section 3 and 4 provides guidances for compiling and running Cayuga. Section 5 serves as a reference to the Cayuga config options. Section 6 explains the input/output system components in Cayuga and the message formats they use. Section 7 describes the regression tes...
متن کاملCayuga: A General Purpose Event Monitoring System
We describe the design and implementation of the Cornell Cayuga System for scalable event processing. We present a query language based on Cayuga Algebra for naturally expressing complex event patterns. We also describe several novel system design and implementation issues, focusing on Cayuga’s query processor, its indexing approach, how Cayuga handles simultaneous events, and its specialized g...
متن کاملRelics of the Antarctic tundra
Many viruses have capsids that are icosahedra: 20-sided nearspheres with triangular faces. Chuan Zhang et al. have created icosahedra consisting purely of DNA, which self-assemble from five-pointed molecular tiles. The authors’ previous research with three-pointed tiles showed that triangular faces make extremely stable building blocks. In the present work, they designed fivepointed tiles using...
متن کاملRelics of Double Radio Sources
We have formed a new sample which consists of extended extragalactic radio sources without obvious active galactic nuclei (AGN) in them. Most of these sources appear to be dead double radio sources. These sources with steep spectra (α < -1.8; S ∝ ν) were identified using the 74 (VLSS) and the 1400 MHz (NVSS) surveys and further imaged using the Very Large Array (VLA) and the Giant Meterwave Rad...
متن کاملRadio Relics in Clusters of Galaxies
In this paper we review the observational results on Relic radio sources in clusters of galaxies. We discuss their observational properties, structures and radio spectra. We will show that Relics can be divided according to their size, morphology, and location in the galaxy cluster. These differences could be related to physical properties of Relic sources. The comparison with cluster condition...
