Jcc is measured by its Peak-to-Peak value in a given time period. It is mathematically defined as where n is a cycle index and N is a number for a given period. Figure 2 shows the relation between Jcc and TPER(n) in a clock waveform. Figure 2. Cycle-to-Cycle Jitter Measurement....

you can combine consumable resource management and resource availability statistics. The grid engine system compares job requirements for disk space with the available capacity and with the most recent reported load value. Available capacity is derived from the internal resource planning. Jobs get dispatc...
The neutron Radiography (NR) or Neutron Imaging (NI) System take place, as a key component, in support of sample irradiation campaigns and require a thorough design survey to get to the most performing system. This paper begins with a presentation of the operational feedback gained from the ...
