E-learning and microformats: A learning object harvesting model and a sample application
(2008)
In order to support interoperability of learning tools and reusability of resources, this paper introduces a framework for harvesting learning objects from web-based content. Therefore, commonly-known web technologies are ...
On the cyclostationary statistics of ultra-wideband signals in the presence of timing and frequency jitter
(Elsevier GMBH, Urban & Fischer Verlag, 2008)
Cyclostationarity is an inherent characteristic of many man-made communication signals, which, if properly recognized, can be exploited for performing various signal-processing tasks. Determining the cyclostationary ...
Cryptanalysis of a cryptosystem based on discretized two-dimensional chaotic maps
(Elsevier Science BV, 2008-11-17)
Recently, an encryption algorithm based on two-dimensional discretized chaotic maps was proposed [Xiang et al., Phys. Lett. A 364 (2007) 252]. In this Letter, we analyze the security weaknesses of the proposal. Using the ...
