Graphite nodules features identifications and damaging micromechanims in ductile irons [PDF]
Fracture and Structural Integrity, 2013 Ductile irons mechanical properties are strongly influenced by the metal matrix microstructure and on the graphite elements morphology. Depending on the chemical composition, the manufacturing process and the heat treatments, these graphite elements can ...

Visual Tracking of Deformation and Classification of Non-Rigid Objects with Robot Hand Probing
Robotics, 2017 Performing tasks with a robot hand often requires a complete knowledge of the manipulated object, including its properties (shape, rigidity, surface texture) and its location in the environment, in order to ensure safe and efficient manipulation.

BOUNDS FOR VOLUMES OF SUB-LEVEL SETS OF POLYNOMIALS AND APPLICATIONS
Tạp chí Khoa học Đại học Đà Lạt, 2022 In this paper, we present some explicit exponents in the estimates for the volumes of sub-level sets of polynomials on bounded sets and applications to the decay of oscillatory integrals and the convergence of singular integrals.

An efficient, scalable, and adaptable framework for solving generic systems of level-set PDEs
Frontiers in Neuroinformatics, 2013 In the last decade, level-set methods have been actively developed for applications in image registration, segmentation, tracking, and reconstruction. However, the development of a wide variety of level-set PDEs and their numerical discretization schemes,

Duality in Fuzzy Sets and Dual Arithmetics of Fuzzy Sets
Mathematics, 2018 The conventional concept of α-level sets of fuzzy sets will be treated as the upper α-level sets. In this paper, the concept of lower α-level sets of fuzzy sets will be introduced, which can also be regarded as a dual concept of upper ...

Reconciling Landmarks and Level Sets [PDF]
18th International Conference on Pattern Recognition (ICPR'06), 2006 Shape warping is a key problem in statistical shape analysis. This paper proposes a framework for geometric shape warping based on both shape distances and landmarks. Our method is compatible with implicit representations and a matching between shape surfaces is provided at no additional cost.

Level Sets and the Uniqueness of Measures [PDF]
Journal of the London Mathematical Society, 1993 A result of Nymann is extended to show that a positive $σ$-finite measure with range an interval is determined by its level sets. An example is given of two finite positive measures with range the same finite union of intervals but with the property that one is determined by its level sets and the other is not.

XFEM/Level-set for modelling of coated inclusion composites
Vietnam Journal of Mechanics, 2017 In this paper, Extended Finite Element method (XFEM) is used to model the embedded coated inclusion composite. The coated inclusion with finite thickness is associated with two level-set functions, which describe its inside and outside interfaces.
