[en] EXFOR - a computerized EXchange FORmat - presents in a convenient compact form experimental numerical data as well as physical information necessary to understand the experiment and interpret the data. Keywords and codes make the information computer intelligible. The structure of EXFOR is briefly described
[en] A standard input format for nuclear structure data is described. The format is sufficiently structured that bulk data can be entered efficiently. At the same time, the structure is open-ended and can accommodate most measured or deduced quantities that yield nuclear structure information
[en] One of the major problems to design and implement control/supervision systems for a process lies in the need to establish an ad-hoc system for each sanitation installation —in the context of this work, Waste Water Treatment Plants (WWTP). Despite WWTPs have similarities to some extent, they have features e.g. plant capacity, instrumentation, layout which are characteristic of each plant that must be taken into account in the process control system design. This involves huge amounts of time and resources from design stages to maintenance, including implementation and start-up phases.
[en] Multiobjective radiotherapy planning aims to capture all clinically relevant trade-offs between the various planning goals. This is accomplished by calculating a representative set of Pareto optimal solutions and storing them in a database. The structure of these representative Pareto sets is still not fully investigated. We propose two methods for a systematic analysis of multiobjective databases: principal component analysis and the isomap method. Both methods are able to extract the key trade-offs from a database and provide information which can lead to a better understanding of the clinical case and intensity-modulated radiation therapy planning in general.
[en] A microcomputer-based system for the continuous collection and analysis of data from a fermentor is described. The system was designed around commercially available hardware and interface and software packages written for microcomputers. Additional programmes were written in BASIC to allow the results to be printed in a specific format. The data read from the fermentor were automatically stored on a floppy disc and analysis on the data can be performed at our convenience. Such method for data collection is not limited to a bioreactor, however, since instruments that require continuous accurate reading, such as GLC, HPLC, etc., could be coupled to a microcomputer system.

[en] Bibliometric techniques were used to create the data base. Nuclear Science Abstracts were scanned for the years 1950 to 1972 inclusive and identified all abstracts of serial publications which pertained to weak interactions. The abstracted articles were classified as either theory or experiment and further classified them according to a subject area typology that developed. It was then determined whether the abstracted theoretical articles were either phenomenology or general theory. Experimental articles were classified according to the technologies employed in the reported experiments. Additional coded data include the authors of the articles and their self-reported attributed locations and the year in which the articles were published. From these data four basic files were created: an article file containing information about each article; an author file containing information about the articles he/she authored or coauthored and his/her location through time; an institution file and a nation file each containing information about the articles published by scientists employed by these institutions or residing in these nations
[en] A major concern in the design of weapons systems is the compatibility of the materials used with each other and with the enclosed environment. Usually these systems require long term storage with a high reliability for proper function at the end of this storage period. Materials selection is then based on both past experience and laboratory accelerated aging experiments to assure this long term reliability. To assist in the task of materials selection a computerized materials compatibility data bank is being established. This data bank will provide a source of annotated information and references to personnel and documents for both the designer and materials engineer to draw on for guidance in materials selection. The data bank storage and information retrieval philosophy will be discussed and procedures for information gathering outlined. Examples of data entries and search routines will be presented to demonstrate the usefulness and versatility of the proposed system
