The donor star of the long-period dwarf nova DX-Andromedae
(1993)
Spectroscopic observations of the long-period dwarf nova DX Andromedae are reported which show that it has a binary period of 0.44167 d, a secondary radial velocity amplitude of 107 km/s, and a projected rotational velocity ...
The 1st measurement of the Lyman continuum emission from normal stars
(1993)
We report the first measurements of Lyman continuum emission from non-degenerate stars. The Wide Field Camera on-board ROSAT detected strong emission from Beta CMa (B1 II-III) and Epsilon CMa (B2 II). Both Kurucz LTE ...
Wittgenstein: Two Source Catalogues and a Bibliography : Catalogues of the Published Texts and of the Published Diagrams, each Related to its Sources
(University of Bergen, 1993)
Wittgenstein's published works have largely appeared as posthumous publications which have been edited by his trustees. We consider it useful to publish these catalogues of correspondences between the published material ...
Dispersal of the entomopathogen Hirsutella cryptosclerotium by simulated rain
(1993-01)
When simulated rain fell 11 m down a rain tower onto sporulating cultures or spore suspensions of Hirsutella cryptosclerotium, a pathogen of the mealybug Rastrococcus invadens, large numbers of spores and mycelial fragments ...
Modelling real time systems functional requirements using existing data flow methods
(University of Hertfordshire, 1993)
This report summarises the data flow models from existing real time systems development methodologies, and describes some of the problems with using them to define real-time system functional requirements. The motivation ...
Elman's model of natural language acquisition
(University of Hertfordshire, 1993)
Elman first aims to give an account of natural language showing how a connectionist system can model its significant features. Using the same network he then goes on to model the acquisition of language by children. This ...

An analysis of automatic differentiation on the VAX
(University of Hertfordshire, 1993)
The reverse accumulation algorithm is an efficient technique for implementing automatic differentiation. It is able to calculate the complete gradient vector of a scalar function to the same degree of accuracy as the target ...
