Y.: Efficient regularization of squared curvature

by Claudia Nieuwenhuis, Lena Gorelick, Olga Veksler, Yuri Boykov - In: IEEE conference on Computer Vision and Pattern Recognition (CVPR , 2014
"... Curvature has received increased attention as an impor-tant alternative to length based regularization in computer vision. In contrast to length, it preserves elongated struc-tures and fine details. Existing approaches are either ineffi-cient, or have low angular resolution and yield results with st ..."

with strong block artifacts. We derive a new model for computing squared curvature based on integral geometry. The model counts responses of straight line triple cliques. The corre-sponding energy decomposes into submodular and super-modular pairwise potentials. We show that this energy can be efficiently

Simulation of a scalar field on a fuzzy sphere

by Fernando García Flores, Xavier Martin , 2009
"... The φ 4 real scalar field theory on a fuzzy sphere is studied numerically. We refine the phase diagram for this model where three distinct phases are known to exist: a uniformly ordered phase, a disordered phase, and a non-uniform ordered phase where the spatial SO(3) symmetry of the round sphere is ..."

The fuzzy approximation scheme [1] consists in approximating the algebra of functions on a manifold with a finite dimensional matrix algebra and in principle provides a regularization of field theory on this space which can be used as an alternative to discretising the underlying space as is done in lattice

Regular left-continuous t-norms,

by Thomas Vetterlein - Semigroup Forum , 2008
"... Abstract A left-continuous (l.-c.) t-norm is called regular if there is an n < ω such that the map x → x a has, for any a ∈ [0, 1], at most n discontinuity points, and if the function mapping every a ∈ [0, 1] to the set {x ∈ [0, 1] : lim y x y a = x} behaves in a specifically simple way. The t-n ..."

Controlled fuzzy parallel rewriting

by Peter R. J. Asveld - New Trends in Formal Languages — Control, Cooperation, and Combinatorics (1997), Lect. Notes. in Comp. Sci. 1218
"... Abstract. We study a Lindenmayer-like parallel rewriting system to model the growth of filaments (arrays of cells) in which developmental errors may occur. In essence this model is the fuzzy analogue of the derivation-controlled iteration grammar. Under minor assumptions on the family of control lan ..."

languages and on the family of fuzzy languages in the underlying iteration grammar, we show that (i) regular control does not provide additional generating power to the model, (ii) the number of fuzzy substitutions in the underlying iteration grammar can be reduced to two, and (iii) the resulting family

Interval Valued Fuzzy Sets from Continuous Archimedean Triangular Norms

by Taner Bilgic, I. Burhan Türksen - Proceedings of the Third IEEE Conference on Fuzzy Systems , 1994
"... this paper is that, for strong and strict De Morgan triples, interval valued fuzzy sets are well defined. Theorem 3 of Turksen (1986) establishes the conditions under which the premise should hold for different families of connectives. Here, we establish the result for strict and strong De Morgan tr ..."

On intuitionistic fuzzy prime bi-ideals of semigroups

by Muhammad Shabir, Muhammad Shoaib Arif, Asghar Khan, Muhammad Aslam
"... Abstract: In this paper, we introduce the notions of intuitionistic fuzzy prime (resp. strongly prime and semiprime) bi-ideals of a semigroup. By using these ideas we characterize those semigroups for which each intuitionistic fuzzy bi-ideal is semiprime and strongly prime. Key words: Intuitionistic ..."

Procedural Semantics for Fuzzy Disjunctive Programs

by With Weak Similarity
"... In the paper, we present a procedural semantics for fuzzy disjunctive programs with weak similarity - sets of graded strong literal disjunctions. We shall suppose that truth values (degrees) constitute a regular residuated lattice L = (L; , ; ),[;\;0; 1). A graded strong literal disjunction will ..."

ANY-TIME FUZZY CONTROLLER

by Edward Shmukler, Dr. Gal, A. Kaminka , 2006
"... Fuzzy logic has been successfully applied in various fields. However, as fuzzy controllers increase in size and complexity, the number of control rules increases exponentially and real-time behavior becomes more difficult. This thesis introduces an any-time fuzzy controller. Much work has been done ..."

The Decay of Accreting Triple Systems as Brown Dwarf Formation Scenario

by Stefan Umbreit, Andreas Burkert, Thomas Henning, Rainer Spurzem , 2005
"... We investigate the dynamical decay of non-hierarchical accreting triple systems and its implications on the ejection model as Brown Dwarf formation scenario. A modified chain-regularization scheme is used to integrate the equations of motion, that also allows for mass changes over time as well as fo ..."

Simpler Short Extenders Forcing- Preserving Strong Cardinals

"... Our aim is to define a version of a simpler short extenders forcing preserving strong cardinals. 1 The Main Preparation Forcing In this section we will redefine the preparation forcing of [6] in order to allow eventually to preserve strong cardinals. The definition will follow those of [6] with cert ..."
