Low-complexity trellis decoding of linear block codes. [PDF]

open access: yes, 1995
The authors introduce a new simple encoding technique which allows the design of a wide variety of linear block codes. They present a number of examples in which the most widely used codes (Reed-Muller, Hamming, Golay, optimum etc.) have been designed ...

Coset Decompositions of Space Groups: Applications to Domain Structure Analysis [PDF]

open access: yes, 1997
Left- and double-coset decompositions of space groups are systematically analysed by putting the emphasis on the introduction of special auxiliary groups. An algorithm is tailored to exploit the specific structure of space groups. The new results are,

Coset-minimal groups [PDF]

open access: yes, 2003
A totally ordered group G (possibly with extra structure) is called coset-minimal if every definable subset of G is a finite union of cosets of definable subgroups intersected with intervals with endpoints in G∪{±∞}. Continuing work in Belegradek et al. (

Deep Learning for Compressed Sensing-Based Blade Vibration Reconstruction From Sub-Sampled Tip-Timing Signals

open access: yesIEEE Access, 2023
Blade tip-timing (BTT) signals are always seriously under sampled, so reconstruction is much needed for vibration analysis. Blade vibration responses are sparse in order domain and classical compressed sensing (CS) algorithms are difficult to reconstruct

Generalized non-stationary multiresolution analysis on locally compact zero-dimensional groups with an arbitrary generating sequence [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
We consider a locally compact zero-dimensional group $(G, \dot+),$ whose coset orders are arbitrary prime numbers. If the orders of the cosets are constant and equal to some prime number, the multiresolution analysis can be constructed by using a ...

Coset spaces and Einstein manifolds with l-conformal Galilei symmetry

open access: yesNuclear Physics B, 2016
The group theoretic construction is applied to construct a novel dynamical realization of the l-conformal Galilei group in terms of geodesic equations on the coset space.

The minimal simple composite Higgs model

open access: yesJournal of High Energy Physics, 2019
Most of the analysis of composite Higgs have focussed on the Minimal Composite Higgs Model, based on the coset SO(5) × U(1) X / SO(4) × U(1) X . We consider a model based on the coset of simple groups SO(7)/ SO(6), with SO(4) × U(1) X embedded into SO(6).

Unitary and non-unitary N = 2 minimal models

open access: yesJournal of High Energy Physics, 2019
The unitary N = 2 superconformal minimal models have a long history in string theory and mathematical physics, while their non-unitary (and logarithmic) cousins have recently attracted interest from mathematicians.

Cut and join operator ring in tensor models

open access: yesNuclear Physics B, 2018
Recent advancement of rainbow tensor models based on their superintegrability (manifesting itself as the existence of an explicit expression for a generic Gaussian correlator) has allowed us to bypass the long-standing problem seen as the lack of ...

The Fischer-Clifford matrices of an extension group of the form 2^7:(2^5:S_6) [PDF]

open access: yesInternational Journal of Group Theory, 2014
The split extension group A(4) = 2^7:Sp_6(2) is the affine subgroup of the symplectic group Sp_8(2) of index 255. In this paper, we use the technique of the Fischer-Clifford matrices to construct the character table of the inertia group 2^7:(2^5:S_6) of ...
