We propose in this paper a method for enhancing vision through fog, based on Blind Source Separation (BSS). BSS method recovers independent source signals from a set of their linear mixtures, where the mixing matrix is unknown. The mixtures are represented in our work by the natural logarithm of the degraded image at different wavelength. These provide an additive mixture of transmittivity coefficient (related to fog) and reflectivity coefficient (related to each point of the scene). [ABSTRACT FROM AUTHOR]

In this paper we will apply a SEC-DED code to the cache level of a memory hierarchy. From the category of SEC-DED (Single Error Correction Double Error Detection) codes we select the Hsiao code. The Hsiao code is a odd-weight-column SEC-DED code. For correction of single-bit error we use a syndrome decoder, a syndrome generator and the check bits generator circuit. [ABSTRACT FROM AUTHOR]
