Absorbing cantor sets and trapping structures
Ergodic Theory and Dynamical Systems, 1991AbstractIt it shown that a minimal attractor for a continuous, lebesgue non-singular transformation on an interval with no wandering intervals is either a periodic orbit, a finite collection of intervals, a simply attracting cantor set, or an absorbing cantor set.

, 1991 This paper suggests a general framework to deal with learning, dynamics and evolution in games and economic environments. In this general set-up we define a (set-valued) solution concept and prove some properties, including existence. We then discuss more specific dynamical processes and show that the general solution concept provides quite intuitive ...

NB-LDPC: Absorbing set and importance sampling
2012 7th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2012The identification of error sources when sub-optimal decoding algorithms are used is an open point both in binary and non-binary LDPC. Here a mathematical definition for absorbing sets in the case of non-binary LDPC is given and several examples are proposed to illustrate it.

Analysis of Absorbing Sets using Cosets and Syndromes
2020 IEEE International Symposium on Information Theory (ISIT), 2020Absorbing sets are combinatorial structures in a Tanner graph that have been shown to characterize iterative decoder failure, and particularly error floor behavior, of LDPC codes. In this paper, we examine the connection between absorbing sets and the syndromes of their support vectors.

Absorbing sets of Fountain codes over noisy channels
2012 26th Biennial Symposium on Communications (QBSC), 2012Although error-prone patterns have been extensively studied for low-density parity-check (LDPC) codes, to the best of our knowledge, they have never been fully explored for Fountain codes. It is shown that dominant trapping sets of Fountain codes are the absorbing sets. They happen in the so-called error floor, corresponding to a significant flattening

Orthogonal measures and absorbing sets for Markov chains
Mathematical Proceedings of the Cambridge Philosophical Society, 1997For a general state space Markov chain on a space (X, [Bscr ](X)), the existence of a Doeblin decomposition, implying the state space can be written as a countable union of absorbing ‘recurrent’ sets and a transient set, is known to be a consequence of several different conditions all implying in some way that there is not an uncountable ...

Ultralight, sound and shock absorbing component set
The Journal of the Acoustical Society of America, 2004The invention relates to an ultralight, sound and shock absorbing component set comprising at least one base layer (2), an intermediate layer (3) and a covering layer (6). The intermediate layer (3) consists of a plurality of hollow bodies (4) arranged next to each other, whose walls are perforated and which thus form a complex labyrinth of hollow ...

Development of Dual‐Setting Calcium Phosphate Cement Using Absorbable Polymer
Artificial Organs, 2013AbstractCalcium phosphate cements used as bone substitutes generally have low mechanical strength compared with the bones of the human body. To solve these needs, we have incorporated hydrogels in the manufacture of samples made of alpha‐tricalcium phosphate (α‐TCP) cement, developing a system of dual‐setting cement.
