Computer support: development

The corrosion inspection and wall thickness measurement of pipes was performed in the classical way both on film and on the monitor using simple software measuring tools. Additionally algorithms were developed for an interactive, computer supported evaluation. 

Computers will be integrated more and more into commercial SEMs and there is an enormous potential for the growth of computer supported applications. At the same time, related instruments will be developed and extended, such as the scanning ion microscope, which uses liquid-metal ion sources to produce finely focused ion beams that can produce SEs and secondary ions for image generation. The contrast mechanisms that are exhibited in these instruments can provide new insights into materials analysis. 

Instrumentation requirements for SEC are somewhat simpler than those of other modes of HPLC, since mobile phase gradients are not used however, adequate computer support for data acquisition and processing is essential. Method development involves finding a suitable solvent for the sample and choosing a mixed bed column or, more often, a set of columns in series to match the pore size of the column(s) with the size distribution of the sample. 

Intact bacteria were first introduced into a mass spectrometer for analysis of molecular biomarkers without processing and fractionation around 1975.6 The ionization techniques available at the time limited analysis to secondary metabolites that could be volatilized, such as quinines and diglycerides, and vigorous pyrolysis of bacteria was explored as an alternative.7 Although biomarkers were destroyed in pyrolysis strategies, computer-supported cluster analysis was developed to characterize pure samples. 

Detailed descriptions of the infrastructure for supporting computer systems validation can be found in Chapters 5 and 6. A sample computer systems development and maintenance methodology can be found in Chapter 7. 

The GLP regulations have been in existence since 1978. From 1984 the FDA began applying these regulations to computer systems, their development, use, and support. The FDA has stated that hardware is considered to be equipment and software is considered to be records under the regulations. This means that computer system development documentation and procedures are now subject to FDA inspection. 

The ultimate selectivity of gas chromatography is determined by the detector. The most selective detectors are spectroscopic, such as Fourier-Transform Infrared or Mass Spectrometer. Automated systems can employ chemometric algorithms to discriminate unresolved chromatographic peaks. These combinations are expensive and require significant computer support. As such, they are more likely to be used in a laboratory for confirmation. Efforts to convert this approach to field units are still under development. The MiniCAMS described above, based on a FPD is a reliable monitor but requires 3-5 min to make a determination. Gas chromatographs also require a source of purified gas for operation and the flame detector requires additional hydrogen and air for operation. This device will have the fewest false positives and the most... 

Techiucal persoimel such as those providing computer system development and support skills should also have the necessary qualifications to fulfill their roles. This requirement is specifically stated in the U.S. 21 CFR Part 11 regulation covering electronic records and electronic signatnres. 

ASPEN Project—a large computer program developed with DOE support as a tool to simulate proposed or existing Industrial processes. Firms (48 so far) commit 15,000- 25,000 at MIT over two years, for which MIT trains their personnel In the use of ASPEN and make available the MIT computer to work real problems of the firm, and to assist In Installing ASPEN on an in-house computer if desired. 

Modeling tools are computerized instruments used to support the application of modeling methods. Support in designing enterprise models through the use of computerized tools can play a crucial role in increasing the efficiency of the development process. The general benefits of computer support are ... 

The use of recent information and communication technology, interdisciplinary teamwork, and an effective network is essential for the shortening of development times, as we have demonstrated. The prerequisites for effective cooperative work are continuous, computer-supported process chains and new visualization techniques. In the engineering solution center (ESC), recent methods and technologies are integrated into a continuous process chain, which includes aU phases of product development, from the first CAD draft to the selection and fabrication of suitable prototypes to the test phase. 

Product modeling creates product model data and is seen as a decisive constituent of the computer-supported product development activities. Product creation includes aU the tasks or steps of product development, firom the initial concept to the tested prototypes. During product modeling, a product model database is created and must support aU relevant data throughout the product s life cycle. 

Perturbation theory and techniques are coming of age. They provide increasing support for the design and analysis of nuclear systems, and for the evaluation of nuclear data. This is evidenced by the large number of perturbation theory based computer codes developed within the last few years. These trends characterize the new codes (1) the extension of conventional perturbation techniques to multidimensional systems and to high-order approximations of the Boltzmann equation (2) the development of methods for implementing new perturbation theory formulations, such as the generalized perturbation theory formulations and (3) the application of perturbation theory formulations to new fields, such as sensitivity studies and the solution of deep-penetration problems. 

In the future, it is anticipated that clinical engineering departments will provide assistance in the application and management of many other technologies that support patient care, including computer support (which includes the development ofvirtual instrumentation), telecommunications, and facilities operations. 

The recent installation of MACCS-II with the Customisation and DBMS Interface modules has provided the capability to interface chemical structures with ancillary data. After receiving training from Molecular Design Limited, the CDD staff and Corporate computer support staff developed screens and sequences to customise MACCS-II for the MSDRL environment, and to replace the current version of MACCS. An orientation program was prepared to acquaint the user community with the new facilities and commands. Technical assistance was given to convert, where necessary, the scientists project files. 

In the design institutes and departments, calculations and theoretical studies performed in support of nuclear safety or with the aim to optimize the design solutions are usually carried out with the help of techniques and computer codes, developed and verified in NSD, IPPE. 

The main characteristics of plant data are their noise because of systematic and coincidental errors and their incompleteness for practical and cost reasons. Computer-supported methodologies allow calculation of closed mass balances even for complex plants, and thus, development of computer models, which relate process parameters such as the composition of the feed material to the operational results e.g., recovery of valuable elements. 

As for the lines of scientific development, the impression is that of a growing expansion towards the most variegate application. Mechanistic studies are more and more developed, profiting of more advanced technique and of the increasing level of instrumental devices available, as well as of computational support, so that the properties of electronically excited states are better and better understood. In turn, the short lifetime and high reactivity characteristic of these species originate always new applications. The present yearly reports have included in the last six years a number of highlights on various aspects of photochemistry. Thus, also from the list of topics considered one can have an idea of the aspects of this discipline. 

Finally, it is very important to emphasize that nuclear industry and specially nuclear reactor must be under permanent and systematic evaluation, using not only the standard methods and computer codes, the nuclear community must support development of new computing tools, integration of qualified evaluation teams to assure that all aspects and specially all safety concern of the nuclear industry are permanently.
