The CMS electromagnetic calorimeter (ECAL) is a high resolution crystal operating at the CERN LHC. It read out 40 MHz (the proton-proton collision rate) in order to provide information hardware-level (Level-1) trigger system, which decides whether full detector must be for each collision. ECAL performance achieved during LHC Run 2 (2015-2018) will presented. increased luminosity with respect 1 ...

The prime objective of the study is to identify the long-run and short-run relationship between Indian stock price viz., BSE SENSEX (hereafter named as BSE) and gold price (GOLD) in India. The daily closing price data were collected for the period of ten years ranging from 1st April 2004 to 31st March 2014 with 2490 observations. The study employed two models: Model one us...

Copying data from devices into main memory is a computationally-trivial, yet time-intensive, task. In order to free the CPU to perform more interesting work, computers use direct memory access (DMA) engines — a special-purpose piece of hardware — to transfer data into and out of main memory. We show that the ability to chain together such memory transfers, as provided by commodity hardware, is ...
