Complex Event Recognition (CER) systems are a prominent technology for finding user-defined query patterns over large data streams in real time. CER evaluation is known to be computationally challenging, since it requires maintaining set of partial matches, and this quickly grows super-linearly the number processed events. We present CORE, novel COmplex event Engine that focuses on efficient cl...

Earth dam is a structure as homogeneous or non-homogeneous forms for raising water level or water supply. Earth dam consist of different parts that one of the main parts is clay core. Choosing an optimal non permeable core which causes reduction of seepage through dam body and also being stable is necessary. The objective of this research is to optimize the geometry of earth dam clay core such ...

Multicasting can be done in two different ways: source based tree approach and shared tree approach. Protocols such as Core Based Tree (CBT), Protocol Independent Multicasting Sparse Mode (PIM-SM) use shared tree approach. Shared tree approach is preferred over sourcebased tree approach because in the later construction of minimum cost tree per source is needed unlike a single shared tree in th...

In this supplement, we analyze the system-level bottlenecks of Shotgun’s scalability on multicore. Currently, we are able to get maximum of about 3− 4× speedup on 8 cores. To analyze multicore performance, we run a series of tests which try to isolate effects of various factors. Our analysis indicates that Shotgun is held back by memory access, but we give suggestions for future improvements to...

electro-facies is a unit of the vertical sediments sequence on the wire-line logs that can be differentiated from the upper and lower units. for detection of the electro-facies interval in kangan and upper dalan formations in south pars gas field, wire-line log and core data analysis (wells a, b, c and d) were used. note, only core data analysis in well a were available. first, thin-sections st...
