Words Guaranteeing Minimum Image
Given a positive integer n and a finite alphabet Σ, a word w over Σ is said to guarantee minimum image if, for every homomorphism φ from the free monoid Σ∗ over Σ into the monoid of all transformations of an n-element set, the range of the transformation wφ has the minimum cardinality among the ranges of all transformations of the form vφ where v runs over Σ∗ . Although the existence of words g...

متن کاملCompressed Image Hashing using Minimum Magnitude CSLBP
Image hashing allows compression, enhancement or other signal processing operations on digital images which are usually acceptable manipulations. Whereas, cryptographic hash functions are very sensitive to even single bit changes in image. Image hashing is a sum of important quality features in quantized form. In this paper, we proposed a novel image hashing algorithm for authentication which i...
متن کاملStochastic Subspace Identification Guaranteeing Stability and Minimum Phase
This paper presents a stochastic subspace identification algorithm to compute stable, minimum phase models from a stationary time-series data. The algorithm is based on spectral factorization techniques and a stochastic subspace identification method via a block LQ decomposition (Tanaka and Katayama, 2003c). Two Riccati equations are solved to ensure both stability and minimum phase property of...
متن کاملSurvivable IP Over WDM: Guaranteeing Minimum Network Bandwidth
A novel survivable IP over WDM network design problem is proposed. The IP network uses lightpath services of the WDM network to implement its IP links. The WDM network can provide unprotected and protected lightpaths, as well as a new lightpath service referred to as survivable pair. The IP network must support two traffic matrices, one under normal conditions and the other whenever there is a ...
