Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

open access: yesAdvanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Fast Adaptive Sparse Iterative Reweighted Super-Resolution Method for Forward-Looking Radar Imaging

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Recently, a sparse super-resolution method based on $L_{1}$ iterative reweighted norm (IRN) has been proposed to improve the azimuth resolution of forward-looking radar.

Forward-start options in the Barndorff-Nielsen-Shephard Model [PDF]

open access: yes
We derive a semi-analytical formula for pricing forward-start options in the Barndorff-Nielsen- Shephard model. In terms of computational time, this formula is equivalent to one-dimensional integration.

An accurate, fast, mathematically robust, universal, non-iterative algorithm for computing multi-component diffusion velocities

open access: yes, 2016
Using accurate multi-component diffusion treatment in numerical combustion studies remains formidable due to the computational cost associated with solving for diffusion velocities.

Evaluation of Plasticity and Creep Parameters From Tensile Stress–Strain Data for a Range of Strain Rates

open access: yesAdvanced Engineering Materials, EarlyView.
This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

Euler's constant, q-logarithms, and formulas of Ramanujan and Gosper

open access: yes, 2003
The aim of the paper is to relate computational and arithmetic questions about Euler's constant $\gamma$ with properties of the values of the $q$-logarithm function, with natural choice of $q$.

Toward Knowledge‐Based Workflows: A Semantic Approach to Atomistic Simulations for Mechanical and Thermodynamic Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Numerical Calculation of Whole-Body Exposure to Beams From mmWave Base Stations Using Superposition of Spherical Waves

open access: yesIEEE Access
Whole-body exposure to beams from fifth-generation (5G) base stations is numerically studied. Since the base stations have the capability for beamforming, the assessment of exposure to all possible beams from such stations must be performed to find the ...

Formulas for series computations

open access: yes, 1991
We describe an algorithm that computes polynomials whose roots are the coefficients of any specific order of the Laurent series of a rational function. The algorithm uses only rational operations in the coefficient field of the function. This allows us to compute with the principal parts of the Laurent series, in particular with the residues of the ...
