Algol-Genius

Algol-Genius, an Algol 60 implementation with features from COBOL, was the brainchild of Börje Langefors. In 1964, assembler was the dominant programming language, but Algol-Genius broke that trend among Datasaab D21 customers. Algol-Genius programs were still in production in the late nineties.

Linear Algebra ALGOL

Theoret ica l B a c k g r o u n d The procedure bisect is designed to replace the procedures tridibi I and 2 given in ES]. All three procedures are based essentially on the following theorem. Given a symmetric tridiagonal matrix with diagonal elements q to cn and off-diagonal elements b, to b, (with b 1 set equal to zero for completeness) and b i 4=0, then for any number 2 let the sequence Po (...

The Optical Spectroscopic Evolution of V1974 Cygni (nova Cygni 1992)

Received ; accepted – 2 – ABSTRACT Optical observations of nova V1974 Cygni (Cygni 1992), spanning a 4 year period, have been used to study its spectroscopic evolution. The data cover a wavelength range from ∼ 3200 − 8000Å and follows the nebular evolutionary phase of the ejecta. We have modeled the integrated fluxes by means of the photoionization code CLOUDY. The models were run at a fixed ab...

Radio Emission from Algol

We report dual circular polarization VLBA observations of Algol made at orbital phases 0.22{0.30 using a diierential phase referencing technique. The ux density of Algol varied from 10{20 mJy during the observations. The radio maps show a double-lobe source separated by 1.6 mas (1.4 times the K star diameter). Although the total emission is only weakly circularly polarized, the individual lobes...
