A High-Order Numerical Method for the Helmholtz Equation with Nonstandard Boundary Conditions
SIAM Journal on Scientific Computing, 35(5), A2255–A2292.
author keywords: difference potentials; boundary projections; Calderon's operators; regular grids; curvilinear boundaries; boundary value problems; variable coefficients; Robin boundary conditions; mixed/piecewise boundary conditions; compact differencing; high-order accuracy
TL;DR:
The approach combines compact finite difference schemes that provide an inexpensive venue toward high-order accuracy with the method of difference potentials developed by Ryaben'kii, introducing a universal framework for treating boundary conditions of any type.

A Bounded and Discretized Nelder-Mead Algorithm Suitable for RFIC Calibration
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS I-REGULAR PAPERS, 60(7), 1787–1799.
author keywords: Calibration; derivative-free optimization; Nelder-Mead direct search algorithm; PLL spurious tone reduction; radio frequency integrated circuit calibration
TL;DR:
It is shown that a gradient descent-based algorithm has difficulty in reducing the VCO control line ripple, while the proposed algorithm reduces the relative power of the first harmonic reference spurs by at least 10 dBc and effectively enables design complexity reduction in the supporting analog calibration circuitry.

Steady states for chemical process plants: A legacy code, time-stepping approach
AICHE JOURNAL, 59(9), 3308–3321.
author keywords: equation-free computations; legacy dynamic simulator; unstable processes; inventories; time-steppers

Improving angular speed uniformity by reparameterization
Computer Aided Geometric Design, 30(7), 636–652.
TL;DR:
The notion of angular speed uniformity as a quality measure for parameter-izations of plane curves and an algorithm to compute uniform reparameterizations for quadratic and cubic curves are introduced and it is proved that only straight lines have uniform rational parameterizations.

Energy stable and efficient finite-difference nonlinear multigrid schemes for the modified phase field crystal equation
JOURNAL OF COMPUTATIONAL PHYSICS, 250, 270–292.
author keywords: Phase field crystal; Modified phase field crystal; Finite difference; Nonlinear multigrid
TL;DR:
This paper presents two unconditionally energy stable finite difference schemes for the modified phase field crystal (MPFC) equation, a sixth-order nonlinear damped wave equation, of which the purely parabolic phase field Crystal (PFC) model can be viewed as a special case.

A fraction free Matrix Berlekamp/Massey algorithm
LINEAR ALGEBRA AND ITS APPLICATIONS, 439(9), 2515–2526.
author keywords: Exact division; Linear recurrences; Matrix recurrences; Block Hankel systems; Block Toeplitz systems; Integer sequences
TL;DR:
This new scalar algorithm has smaller intermediate values than the known fraction free Berlekamp/Massey algorithm and performs all operations in the integral domain, so all divisions performed are exact.
