The “Empirical Conformational Energy Program for Peptides (ECEPP)” by Scheraga and coworkers which calculates the conformational energies of given peptide conformations was adapted for use with the CGK TR440 computer system. New programs for energy minimization, statistical data analysis and graphical display of peptide conformations were added. In this way the range of application of the original ECEPP program was considerably extended. At the same time, its handling was greatly simplified by an improved data input/output

<p>Since the typical so-called microprogrammed system provides only hardware oriented input-output facilities, it is highly desirable to supplement this with a nucleus of software supported I/O routines.</p><p>A proposal is set forth for such a nucleus system to be implemented at the lowest level of a multi-level computer system.</p><p>Although the proposal is of a general nature, specific reference is also made to the Rikke-1 hardware being developed in the Computer Science Department at Aarhus University.</p>

The use of radioimmunoassay (RIA) as a routine aid to clinical diagnosis makes it important that procedures for estimating the potency of each test sample are good, ancl that the validity of assumptions implicit in the calculations is regularly monitored. The task is non-trivial: if a laboratory regularly conducts varied assays, with perhaps 50-500 test samples in each, even simple manual processes (graphical or arithmetical) are very time-consuming. Only by making RIA analysis a standard computer task, can it be handled satisfactorily. If a comprehensive program serves many centres, the costs of “writing can be relatively small and other benefits can be secured — reduction in numerical mistakes, thorough examination of the adequacy of fitted response curves, production of limits of error for potency estimates, ancl ease of managing files.This paper is concerned with the principles that should underlie RIA software, and with requirements in respect of input, output, ancl analytical computations. Though not a detailed specification, it is a step towards producing a good program easily moved from one computer system to another and suitable for the computer facilities now becoming available in hospitals. If a proposed new program fails to supply many of the features described below, practitioners of radioimmunoassay not themselves expert hi statistics will be unwise to accept it as sufficient for their needs. Ease of input ancl clarity of output are essential but not sufficient in themselves. A user who adopts an apparently "simple" program may be safe for much of the time, but the occasional anomalous assay may lead to unsuspecting acceptance of wholly untrustworthy numerical conclusions.

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.
