Weighted Fourier Frames on Self-Affine Measures
Continuing the ideas from our previous paper, we construct Parseval frames of
weighted exponential functions for self-affine measures
Weighted Fourier frames on fractal measures
We generalize an idea of Picioroaga and Weber to construct Paseval frames of
weighted exponential functions for self-affine measures
Digital preservation strategies for AV content
The mass digitisation of analogue archive holdings plus the transition to tapeless production for new content means AV archives inevitably face the prospect of file-based archiving solutions using IT storage technology. But what is the long-term Total Cost of Ownership (TCO) of these systems, which file formats should be used, what storage technologies make sense, what are the risks involved, what is the additional cost of managing these risks, and what new software approaches can be applied? These are all issues being explored by major broadcasters, national archives and technology specialists in the European PrestoPrime project and the UK AVATAR-m project
