A Universal Logging System for LHCb Online

Event Logging and Distribution for the BaBar Online System

We discuss the BABAR experiment software and computing infrastructure used for event logging and distribution to prompt reconstruction system. The raw data for typical BABAR events is about 30-50 kB per event. During the data taking a 100 Hz stream of events is collected from a farm of 32 online computers amounting to about 3-5 MB/s. A robust and efficient multi-threaded, TCP/IP based logging m...

Online Dimensional Controlling System for Drilling

The drilling is well known as one of the most common hole making processes in the industry.Due to close tolerance requirement for drilled holes in the most of work pieces, onlinecontrolling of the diameter of drilled holes seems to be necessary. In the current work, an onlinedimensional controlling system was developed for drilling process. Doing this, drilling processwas executed in different ...

The Lhcb Online Luminosity Monitoring and Control

The LHCb experiment searches for New Physics by precision measurements in heavy flavour physics. The optimization of the data taking conditions relies on accurate monitoring of the instantaneous luminosity, and many physics measurements rely on accurate knowledge of the integrated luminosity. Most of the measurements have potential systematic effects associated with pileup and changing running ...
