The confluence of sharply rising Operations and Maintenance (O M) costs. NRC requested Individual Plant Examinations (IPEs) and increased personal computer capabilities gave rise to the R R Workstation. Its uses and maintains-current PSA models and databases for individual plants to perform O M planning and scheduling, and uses the PSA in IPE models to identify plant design, procedure and operational vulnerabilities. The Risk and Reliability Workstation Alliance was organized by EPRI to support the R R Workshop in order to achieve O M cost reduction, plant productivity and safety enhancement through risk-based, user-friendly, windowed software louls (Table 3.6 8). The Alliance, initiated in 1992, includes 25 U.S. utilities and four international partners from Spain, France, Korea, and Mexico. SAIC is the prime contractor for the R R Workstation, with participation of five other PSA vendors. 

Updated computational tools. As in previous editions, I provide many opportunities for the use of personal computers in problem solving. The third edition of this book included MATHCAD worksheets and DOS-based Basic language (and compiled) programs. To these programs I have added Windows-friendly Visual Basic versions of those earlier programs that are easier to use and have greater capabilities. There is also a new Visual Basic pure-component database that can be used as a stand-alone program or accessed by the... 

Molecular mechanics is an interpolative method. It thus follows that the strain energy and the stmcture of a very strained species may not be reliably computed based on a parameterization scheme fitted with a set of experimental data obtained from unstrained molecules, as this amounts to extrapolation. Therefore, in order to obtain a generally reliable force field, extreme cases must be included in the fitting procedure of the force field. The speed with which structure optimizations are produced (seconds of CPU time on a simple personal computer for molecules with a few hundred atoms) does not place any restriction on the size of a database for the... 

The earliest chemical databases which became available on PC s were not structure-based. In the UK one of the first chemical databases distributed on personal computers was the hazards database CHEMDATA which was developed at the Chemical Emergency Centre at Harwell. This was a database created primarily for the emergency services to help deal with chemical emergencies. Initially, the database was offered as an online service, but obviously the need to keep this service operational 24 hours a day, 7 days a week, put tremendous strains on the operators of the service and as soon as the first microcomputers were introduced, the Chemical Emergency Centre recognised their potential for distributing the data in another form. 

Computer-based sources include on-line and CD-ROM databases containing abstracts from health and safety journals, information on hazardous chemicals and details of relevant legislation. Computer programmes are also available containing statistical data on topics such as personal protective equipment performance and noise data analysis.

In spectra-structure correlation problems, the spectral representations, be it for IR, for mass, or for any other spectroscopy, are usually input as sets of equidistant intensities with significantly high resolution. Such inputs require hundreds if not thousands of units on input. Additionally, the intensities of spectra are given as real values and mostly large data bases of spectra have to be taken into account if reliable predictions are to be expected (see Spectroscopic Databases). Therefore, spectra-structure correlation problems have to be implemented on larger and faster work-stations (or mainframes) rather than on personal computers. ...
