  • Data Integrity The Checksum Procedure When transmitting data using contactless technology it is very likely that interference will be encountered, causing undesired changes to the transmitted data and thus leading to transmission errors (Figure 7.1). A checksum can be used to recognise transmission errors and initiate corrective measures, for example the retransmission of the erroneous data blocks. The most common checksum procedures are parity checks, XOR sum and CRC.

  • The second edition of this accessible book provides readers with an introductory treatment of communication theory as applied to the transmission of information-bearing signals. While it covers analog communications, the emphasis is placed on digital technology. It begins by presenting the functional blocks that constitute the transmitter and receiver of a communication system. Readers will next learn about electrical noise and then progress to multiplexing and multiple access techniques.

  • Sensor Fundamentals Digital techniques have become increasingly popular in processing sensor outputs in data acquisition, process control, and measurement. Generally, 8-bit microcontrollers (8051-based, for example) have sufficient speed and processing capability for most applications. By including the A/D conversion and the microcontroller programmability on the sensor itself, a “smart sensor” can be implemented with self-contained calibration and linearization features, among others. A smart sensor can then interface directly to an industrial network as shown in Figure 1.2.4.

  • To bring the broadest range of experts into the development of evidence reports and health technology assessments, AHRQ encourages the EPCs to form partnerships and enter into collaborations with other medical and research organizations. The EPCs work with these partner organizations to ensure that the evidence reports and technology assessments they produce will become building blocks for health care quality improvement projects throughout the Nation. The reports undergo peer review prior to their release.

  • In shared-nothing database systems, data often needs to be moved whenever there is a join or an aggregation process for which the data requires repartitioning across the segments. As a result, the interconnect serves as one of the most critical components within Greenplum Database. Greenplum’s gNet interconnect (Figure 8m) optimizes the flow of data to allow continuous pipelining of processing without blocking on all nodes of the system.

  • To solve these problems, the SEQ and PREDATOR systems introduce a spe- cial sublanguage, called SEQUINfor queries on sequences [Seshadri et al. 1994, 1995; Seshadri 1998]. SEQUIN works on sequences in combination with SQL working on standard relations; query blocks from the two languages can be nested inside each other, with the help of directives for converting data be- tween the blocks.
