Surface Qualification Toolpath Optimization for Hybrid Manufacturing
Journal of Manufacturing and Materials Processing, 2021 Hybrid manufacturing machine tools have great potential to revolutionize manufacturing by combining both additive manufacturing (AM) and subtractive manufacturing (SM) processes on the same machine tool.

Deformation of string topology into homotopy skein modules [PDF]
, 2003 Relations between the string topology of Chas and Sullivan and the homotopy skein modules of Hoste and Przytycki are studied. This provides new insight into the structure of homotopy skein modules and their meaning in the framework of quantum topology ...

Twisted Alexander polynomials detect the unknot [PDF]
, 2006 The group of a nontrivial knot admits a finite permutation representation such that the corresponding twisted Alexander polynomial is not a unit.Comment: This is the version published by Algebraic & Geometric Topology on 14 November ...

Electronic Research Archive, 2023 We propose an asymptotic concentration approach combined with isogeometric analysis (IGA) for the topology optimization of two-dimensional (2D) linear elasticity structures under the commonly-used framework of the solid isotropic materials and penalty ...

Temperature Correlations in a Finite Universe [PDF]
, 1998 We study the effect of a finite topology on the temperature correlations of the cosmic microwave background in a flat universe. Analytic expressions for the angular power spectrum are given for all possible finite flat models.

Clique topology reveals intrinsic geometric structure in neural correlations [PDF]
, 2015 Detecting meaningful structure in neural activity and connectivity data is challenging in the presence of hidden nonlinearities, where traditional eigenvalue-based methods may be misleading. We introduce a novel approach to matrix analysis, called clique

geometrical versus topological properties of manifolds [PDF]
Journal of the Institute of Mathematics of Jussieu, 2005 given a compact $n$-dimensional immersed riemannian manifold $m^n$ in some euclidean space we prove that if the hausdorff dimension of the singular set of the gauss map is small, then $m^n$ is homeomorphic to the sphere $s^n$. also, we define a concept of finite geometrical type and prove that finite geometrical type hypersurfaces with a small set ...

Tight contact structures on Seifert manifolds over T^2 with one singular fibre [PDF]
, 2005 In this article we classify up to isotopy tight contact structures on Seifert manifolds over the torus with one singular fibre.Comment: Published by Algebraic and Geometric Topology at http://www.maths.warwick.ac.uk/agt/AGTVol5/agt-5-34.abs ...

The canonical partial metric and the uniform convexity on normed spaces
Applied General Topology, 2005 In this paper we introduce the notion of canonical partial metric associated to a norm to study geometric properties of normed spaces. In particular, we characterize strict convexity and uniform convexity of normed spaces in terms of the canonical ...
