The paper presents a controller designed to be highly interoperable in the context of distributed instrumentation systems. Interoperability is achieved by adopting strong standards - the IEEE 1451.1 Std to be more precise - and by using cross-platform, manufacturer-independent technologies such as Web Services. The 1451.1 Std contributes with its information model to represent data and organize functionalities...
Modern distributed systems are built with numerous different computing platforms, which can be based on different hardware and operating systems. In this context, the development of multi-platform device drivers may contribute for a better scalability of dynamic distributed systems. A Java-based device driver for a controller area network card was implemented, and it is intended for utilization on...
The electromagnetic calorimeter of the CMS experiment at CERN is an homogeneous calorimeter made of about 80000 Lead Tungstate crystals, that will start to operate at the LHC at the end of 2007. From June to November 2006, ten barrel Supermodules (1700 crystals each) were exposed to beam at CERN SPS, both in standalone and in association with portions of the Hadron Calorimeter. We present the description...
For an efficient data taking, the electromagnetic calorimeter (ECAL) data of the CMS experiment must be limited to 10% of the full event size (1 MB). Other requirements limit the average data size to 2 kB per data acquisition link. These conditions imply a reduction factor of close to twenty on the data collected. The data filtering in the readout of the ECAL detector is discussed. Test beam data...
This paper presents the concept of reconfigurable sensing channel characteristics inverse model in auto-calibration measurement systems, particularly for water quality measuring systems. The inverse model implementation is supported on an advanced FPGA reconfigurable embedded control and acquisition system (CompactRIO). Model blocks, such as polynomial and neuronal, are on-line updated (reconfigured)...
