Radio Observations of Algol . II . Computation of Close Stellar Encounters
We present here new astrometric measurements of Algol's position made with Very Long Baseline Interferometry. Using these measurements, along with a new estimate of the node of the inner binary and other orbital elements from the literature, we compute a new proper motion, with uncertainties six times less than those of Hipparcos. We compute the trajectories of Algol (using the new proper motio...
متن کاملAlgol-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.
متن کاملLinear 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 (...
متن کاملRadio 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...
متن کاملAlgol-like Language
We present a denotational semantics for an Algol-like language Alg, which is fully abstract for the second order subset of Alg. This constitutes the rst signiicant full abstraction result for a block structured language with local variables. As all the published`test equivalences' 13, 8, 23] for Algol-like languages are contained in the second order subset, they can all be validated (easily) in...
