− In the last years the increased interest about power quality, forced international working groups to define new standards for testing and measurement techniques. In this paper a pc-based power quality instrument is proposed, according to IEC 61000-4-7 and standard IEC 61000-4-30. It is a low-cost and easily reconfigurable instrument able to measure harmonics, interharmonics and amplitude dist...

In process automation batch processes play a dominant role. With ISA SP88 and its IEC standard equivalent IEC 61512, there is a standard available covering the description of batch processes and plants over several hierarchical layers. For the instrumentation and automation components in all industrial systems there is a trend towards distributed solutions. The function block oriented IEC 61499...

The ISO/IEC 17799 standard (2005) is commonly viewed as a necessary element in information security management. However, there is no empirical evidence of the usefulness of the standard in practice. To study this issue, this study analyses the implementation experiences of four organisations that have implemented the ISO/IEC 17799 (2005) standard. Through semi-structured interviews, the results...

Production code generation with Model-Based Design has replaced document-based development and manual coding in various automotive domains such as chassis and powertrain. Safety-related applications are increasingly developed using Model-Based Design as well. For these applications, software development and quality assurance activities within Model-Based Design must meet the requirements of the...

The development of digital video technology in the 1980s has made it possible to use digital video compression in various kinds of applications. The effort to develop standards for coded representation of moving pictures, audio, and their combination is carried out in the Moving Picture Experts Group (MPEG). MPEG is a group formed under the auspices of the International Organization for Standar...

Introduction: Due to its simplicity, fast response and high reliability, ion chamber detectors are one of the most suitable dosimetry instruments for X and gamma rays. The dosimeter    of photon beams, which used in radiotherapy centers, requires high accuracy and should pass requirements of IEC 60731 standards. About 80 percent of the IEC 60731 standard tests such as stabil...
