Coppersmith, Krawczyk, and Mansour ([CKM93]) presented at Crypto '93 a promising stream cipher, the shrinking generator. It is based on linear shift registers with linear feedback. The output bits of one shift register decide which of the output bits of the other shift registers are used and which are discarded. The design is well suited for hardware implementation. In software shift registers ...

The purpose of this study was to investigate the potential of a constructivist approach to context-based video instruction for enhancing learning. To achieve this purpose, the authors examined whether video-based instruction that was developed using constructivist theory can affect student learning (i.e., comprehension and retention) and motivation (i.e., attention, relevance, confidence, and s...

This paper consists of a review of current trends in web-based instruction and a review of a representative sample of web-based instruction efficacy research. The review of the current state of web-based instruction yields two principle themes: a) The prevalence of web-based instruction is growing exponentially, particularly in lifelong learning and corporate training; and b) The line between a...
