Simplifying The Non-Manifold Topology Of Multi-Partitioning Surface Networks
… the geometric complexity of a general surface: non-manifold or not) and the topological complexity of a closed, manifold surface. But there has been no attempt so far to reduce redundant topological features which are unique to non-manifold surfaces, such as curves and points where multiple …

Approximating, Editing, and Processing Free -Form Motion
… any connected triangle mesh (including non-manifold and non-orientable surfaces). This representation is useful not only for free-form motion processing but also for general geometric mesh editing.

An Algorithm for Triangulating 3D Polygons
… for obtaining a triangulation of multiple, non-planar 3D polygons. The output minimizes additive weights, such as the total triangle areas or the total dihedral angles between adjacent triangles. Our algorithm generalizes a classical method for optimally triangulating a single polygon. The …

Design of transfers from Earth-Moon L 1/L2 libration point orbits to a destination object
… in the vicinity of Earth-Moon L1 and L2 is nontrivial. Routine transfers between an Earth-Moon L1/L2 facility and Mars also requires design strategies to deliver trajectory arcs that are characterized by a coupling between different multi-body gravitational environments across two-, three- …

Virtual topology based hex-dominant meshing and re-meshing
Computer-aided engineering methods have been increasingly used in various industries to support the design of complex systems and validate their performance by simulating their physical behaviour. This created a need to generate fit-for-purpose analysis models with a turnaround time comparable to …

Metric Geometry of Finite Subset Spaces
… by X(n), consists of n-point subsets of X (i.e., nonempty subsets of cardinality at most n) with the quotient topology induced by the unordering map q:X^n--> X(n), (x_1,...,x_n)-->{x_1,...,x_n}. That is, a subset A of X(n) is open if and only if its preimage under q is open in the product space …
