Fractal-wavelet-fusion-based re-ranking of joint roughness coefficients
Nowadays, Barton’s Joint Roughness Coefficients (JRC) are widely used as the index for roughness and as a challenging fracture property. When JRC ranking is the goal, deriving JRC from different fractal/wavelet procedures can be conflicting. Complexity increases when various rankings outcome from different calculation methods. Therefore, using Barton’s JRC, we cannot make a decision based on th...
متن کاملA combinatorial formula for fusion coefficients
Using the expansion of the inverse of the Kostka matrix in terms of tabloids as presented by Eğecioğlu and Remmel, we show that the fusion coefficients can be expressed as an alternating sum over cylindric tableaux. Cylindric tableaux are skew tableaux with a certain cyclic symmetry. When the skew shape of the tableau has a cutting point, meaning that the cylindric skew shape is not connected, ...
متن کاملAutonomous Robot Navigation using Flatness- based Control and Multi-Sensor Fusion
This research work contains results on flatness-based control and sensor fusion for mobile robot systems. Flatness-based control is applicable to differentially flat systems i.e. to systems the behavior of which is determined by the trajectory of a finite collection of quantities, consisting of the flat output and its derivatives [Mounier, H. & Roudolf, J. (2001)],[Rouchon, P. (2005)]. Flatness...
متن کاملSituating Flatness
Our paper, ‘Human Geography without Scale’ (Marston et al. 2005), is developed in two parts: a critique that is immanent to scale, where we show that, even on the grounds of contemporary spatial theory, the concept is deficient; and a critique that is extrinsic to those grounds, where we make a contribution to an alternative ontology that does not rely on the transcendental abstraction of scale...
متن کاملCriteria for Flatness and Injectivity
Let R be a commutative Noetherian ring. We give criteria for flatness of R-modules in terms of associated primes and torsion-freeness of certain tensor products. This allows us to develop a criterion for regularity if R has characteristic p, or more generally if it has a locally contracting endomorphism. Dualizing, we give criteria for injectivity of R-modules in terms of coassociated primes an...
