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.

Weak Approachability of Convex Sets in Absorbing Games
Mathematics of Operations ResearchIn this paper, we extend previous results on weak approachability in generalized quitting games with vector payoffs to the general case of absorbing games. Specifically, we show that a necessary condition and a different sufficient condition for weak approachability of a convex set, established by Flesch, Laraki, and Perchet, remain valid in the ...

On absorbing sets of structured sparse graph codes
2010 Information Theory and Applications Workshop (ITA), 2010In contrast to the capacity approaching performance of iteratively decoded low-density parity check (LDPC) codes, many practical finite-length LDPC codes exhibit performance degradation, manifested in a so-called error floor. Previous work has linked this phenomenon to the presence of certain combinatorial structures within the Tanner graph ...

On Markov decision models with an absorbing set
2006We study a countable state and action Markov decision process with bounded rewards occurring up to the entrance into an absorbing set. Two optimality criteria are considered, the classical total reward criterion and a target-level criterion. For all discount factors smaller than a critical one, the standard results in dynamic programming (optimality ...

Absorbing Set Analysis of Codes from Affine Planes
2017We examine the presence of absorbing sets, fully absorbing sets, and elementary absorbing sets in low-density parity-check (LDPC) codes arising from certain classes of finite geometries. In particular, we analyze the absorbing set spectra of LDPC codes from finite Euclidean planes.
