Given the exponential growth rate of medical data and the accompanying biomedical literature, more than 10,000 documents per week (Leroy et al., 2003), it has become increasingly necessary to apply data mining techniques to medical digital libraries in order to assess a more complete view of genes, their biological functions and diseases. Data mining techniques, as applied to digital libraries,...

We evaluate the usage of a Digital Library with many different collections, by examining its log files, and we concluded that the access points that the users mostly refer to, depend heavily on the type of content of the collection. We also found that most users not only tend to use simple query structures (e.g. one search term) and very few operations per session but they also reduce the compl...

Rabin's cryptosystem was proved to be as hard as factorization. However, Rabin's digital signature schemes is probabilistic. This paper shows two eecient Rabin type digital signature schemes, a basic scheme and an improved scheme. Both schemes run much faster than Rabin's scheme. They are deterministic and the size of a signature is much smaller than that of a signature in Rabin's scheme. Furth...

The issue of usability has concerned the Digital Libraries community, at least peripherally, over many years. There is, after all, little point in delivering sophisticated libraries with novel features if those systems are then ignored by the intended users because they are too difficult to use or do not offer the key features that users require. However, the challenge of how to deliver Digital...

This application note describes the use and implementation of elliptic curve digital signature algorithm (ECDSA) on the MAXQ1103 microcontroller's modular arithmetic accelerator (MAA) module. Performance figures are given for a standard 160-bit curve specified in Standards for Efficient Cryptography published by Certicom®.

There is a multiplicity of methods available for assessing the usability and use of any information retrieval (IR) system: some empirical, some relying more on expert review; some appropriate to questions about the details of a particular interface design, others better suited to understanding the ways such systems impact on working practices. In this paper, we present the PRET A Reporter frame...
