Blind identification of an unknown interleaved convolutional code

We give here an efficient method to reconstruct the block interleaver and recover the convolutional code when several noisy interleaved codewords are given. We reconstruct the block interleaver without assumption on its structure. By running some experimental tests we show the efficiency of this method even with moderate noise

Appreciation of the Sustainability of the Tourism Industry in Cyprus

Because of their specific features (isolation, important sea shores, difficult access, scattering, limited natural resources, prone to cultural disasters, large imports, etc.) islands and small island states need to be protected. They represent case studies regarding sustainable tourism, just like arid zones and mountainous regions. This article takes Cyprus as an example to assess positive and negative aspects which, from a tourist point of view, characterize each of the traditional pillars of sustainability: social, environmental and economic, including patrimonial and cultural. The appraisal as described is largely positive.Cyprus; Sustainability; Tourism; Social; Economic; Environmental; Island
