A Moment-Based Shape Similarity Measurement for Areal Entities in Geographical Vector Data
ISPRS International Journal of Geo-Information, 2018 Shape similarity measurement model is often used to solve shape-matching problems in geospatial data matching. It is widely used in geospatial data integration, conflation, updating and quality assessment. Many shape similarity measurements apply only to

Solution Synthesis of Actinide Chalcogenide and Oxychalcogenide Nanoparticles
Angewandte Chemie, EarlyView.We report the synthesis of UOS, UOSe, and US2 nanoparticles under colloidal conditions. The magnetic properties were measured of all three materials and compared to prior studies of UO2 nanoparticles. Nanoparticle phases were determined using powder diffraction, and size by transmission electron microscopy.

Dynamic planar convex hull [PDF]
, 2002 In this paper we determine the computational complexity of the dynamic convex hull problem in the planar case. We present a data structure that maintains a finite set of n points in the plane under insertion and deletion of points in amortized O(log n ...

A convex body with chaotic random convex hull [PDF]
, 2013 The asymptotic behavior of the size of the convex hull of uniformly random points in a convex body in Rd is known for polytopes and smooth convex bodies. These are the lower and the upper bound for a general convex body.

The Interoperability Challenge in DFT Workflows Across Implementations
Advanced Intelligent Discovery, EarlyView.Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.

A Convex Hull Approach to Counterfactual Analysis of Trade Openness and Growth [PDF]
In this paper, we apply a convex hull approach to counterfactual analysis of trade openness and growth. The experiments we choose evaluate the importance of trade openness for growth across African countries. Specifically, we ask the question “what would

Exploiting Sparsity in Polyhedral Analysis: 12th International Symposium, SAS 2005, London, UK, September 7-9, 2005. Proceedings [PDF]
, 2005 The intrinsic cost of polyhedra has lead to research on more tractable sub-classes of linear inequalities. Rather than committing to the precision of such a sub-class, this paper presents a projection algorithm that works directly on any sparse system of
