Discrete Applied Mathematics, 2022 The study of structural graph width parameters like tree-width, clique-width and rank-width has been ongoing during the last five decades, and their algorithmic use has also been increasing [Cygan et al., 2015]. New width parameters continue to be defined, for example, MIM-width in 2012, twin-width in 2020, and mixed-thinness, a generalization of ...

On the thinness and proper thinness of a graph [PDF]
Discrete Applied Mathematics, 2019 Graphs with bounded thinness were defined in 2007 as a generalization of interval graphs. In this paper we introduce the concept of proper thinness, such that graphs with bounded proper thinness generalize proper interval graphs. We study the complexity of problems related to the computation of these parameters, describe the behavior of the thinness ...

Thinning, Entropy, and the Law of Thin Numbers [PDF]
IEEE Transactions on Information Theory, 2010 Renyi's "thinning" operation on a discrete random variable is a natural discrete analog of the scaling operation for continuous random variables. The properties of thinning are investigated in an information-theoretic context, especially in connection with information-theoretic inequalities related to Poisson approximation results.

Vectorization in graphics recognition: to thin or not to thin [PDF]
Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002 Vectorization, i.e. raster-to-vector conversion, is a central part of graphics recognition problems. In this paper, we discuss the pros and the cons of basing one's vectorization process on skeletonization. While distance skeletons have proven to be robust and precise, they tend to distort the results at line extremities and junctions.

From thin objects to thin concepts?
Theoria, 2023 AbstractIn this short paper we consider Linnebo's thin/thick dichotomy: first, we show that it does not overlap with the very common one between abstract/concrete objects; second, on the basis of some difficulties with the distinction, we propose, as a possible way out, to move from thin/thick objects to thin/thick concepts.

Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet: is land-terminating ice thinning at anomalously high rates? [PDF]
, 2008 Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories have been proposed which provide a link between climate

The Saffman-Taylor problem for an extremely shear-thinning fluid [PDF]
, 2007 We consider a steady flow driven by pushing a finger of gas into a highly shear-thinning power-law fluid, with exponent n, in a Hele-Shaw channel. We formulate the problem in terms of the streamfunction , which satisfies the p-Laplacian equation (with ),

Pre-commercial thinning of beech (Fagus sylvatica L.) [PDF]
, 2006 This paper reports early effects of stump height on the growth and natural pruning of potential crop trees after pre-commercial thinning of a young stand of naturally regenerated beech (Fagus sylvatica L.) in Denmark.
