Paired Pointset Traversal
In the Paired Pointset Traversal problem we ask whether, given two sets A = {a1, . . . , an} and B = {b1, . . . , bn} in the plane, there is an ordering π of the points such that both a π(1), . . . , aπ(n) and bπ(1), . . . , bπ(n) are self-avoiding polygonal arcs? We show thatPaired Pointset Traversal is NP-complete. This has consequences for the complexity of computing the Fréchet distance of ...
متن کاملCalculation of Totally Optimized Button Configurations Using Fitts' Law
This paper addresses the problem of optimal placement and configuration for a set of buttons on a graphical user interface (GUI). We present an optimization algorithm that reduces the average time necessary for pointing device motions. Fitts’ law (Fitts 1954) is used to estimate the transfer time for cursor movements between buttons. Numerous studies in the literature focus on the verification ...
متن کاملAn Element-Based Spectrally Optimized Approximate Inverse Preconditioner for the Euler Equations
We introduce a method for constructing an element-by-element sparse approximate inverse (SAI) preconditioner designed to be effective in a massively-parallel spectral element modeling environment involving nonsymmetric systems. This new preconditioning approach is based on a spectral optimization of a low-resolution preconditioned system matrix (PSM). We show that the local preconditioning matr...
متن کاملEla Spectrally
An n × n complex sign pattern matrix S is said to be spectrally arbitrary if for every monic nth degree polynomial f(λ) with coefficients from C, there is a complex matrix in the complex sign pattern class of S such that its characteristic polynomial is f(λ). If S is a spectrally arbitrary complex sign pattern matrix, and no proper subpattern of S is spectrally arbitrary, then S is a minimal sp...
متن کاملEngineering nanocolumnar defect configurations for optimized vortex pinning in high temperature superconducting nanocomposite wires
We report microstructural design via control of BaZrO3 (BZO) defect density in high temperature superconducting (HTS) wires based on epitaxial YBa2Cu3O7-δ (YBCO) films to achieve the highest critical current density, Jc, at different fields, H. We find the occurrence of Jc(H) cross-over between the films with 1-4 vol% BZO, indicating that optimal BZO doping is strongly field-dependent. The matc...
