H IIRegion Statistics in Barred and Non-Barred Galaxies
(1996)
We present new high quality Ha continuum-subtracted images of the grand design galaxies NGC 157, NGC 3631, NGC 6764, and NGC 6951, two of them barred and two non-barred, and describe the statistical properties of the HII ...
NLTE spectral analysis of helium-rich sdO stars from the southern HK survey.
(Astronomical Society of the Pacific, 1996)
We have determined effective temperatures, surface gravities, and helium-to-hydrogen abundance ratios by fitting NLTE model atmospheres to high signal-to-noise- spectra of eight helium-rich sdO stars detected in the southern ...
Teaching client server computing to undergraduates and postgraduates
(University of Hertfordshire, 1996)
An academic course on Client Server computing will bring together aspects of computer science which would normally be taught in separate courses, in subjects such as Databases, Computer Networks and System Development. A ...
Environmental management for arable agriculture : An Eco-rating system for pesticide use
(1996)
The University of Hertfordshire, funded by MAFF and in collaboration with ADAS and IACR-Rothamsted, is currently developing a computer-based decision support system to encourage and enhance best practice within arable ...
Formal methods: no cure for faulty reasoning
(University of Hertfordshire, 1996)
Owing to the benefits commonly associated with their use and links with scientific culture, formal methods have become closely identified with the design of safety-critical systems. But, despite the mathematical nature of ...
Sharing storage using dirty vectors
(Society for Industrial and Applied Mathematics (SIAM Press), 1996)
Consider a computation F with n inputs (independent variables) and m outputs (dependent variables) and suppose that we wish to evaluate the Jacobian of F. Automatic differentiation commonly performs this evaluation by ...
Towards a more balanced understanding of motor control systems
(1996)
Roberts's book provides a reasonably thorough guide to the physiology and biomechanics of balance, unfortunately the discussion of the neural and cognitive aspects of motor control is less satisfactory. We propose that ...
