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.

Summation formulae and Stirling numbers

open access: yes, 2009
We exploit methods of operational and combinatorial nature to get a class of summation formulae involving special functions and polynomials. The results obtained in this paper complete and integrate previous investigations obtained with different ...

Whipple-type 3F2-series and summation formulae involving generalized harmonic numbers

open access: yes, 2018
By applying the derivative operator to Whipple-type [Formula: see text]-series identities and utilizing L’Hôspital rule, two families of summation formulae involving generalized harmonic numbers are established.

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.

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Certain Applications of Generalized Kummer’s Summation Formulas for 2F1

open access: yes, 2021
We present generalizations of three classical summation formulas 2F1 due to Kummer, which are able to be derived from six known summation formulas of those types.

Poisson Summation Formula for The Space of Functionals

open access: yes, 2004
In our last work, we formulate a Fourier transformation on the infinite-dimensional space of functionals. Here we first calculate the Fourier transformation of infinite-dimensional Gaussian distribution $\exp(-πξ\int_{-\infty}^{\infty}α^2(t)dt)$ for $ξ\in{\bf C}$ with Re$(ξ)>0$, $α\in L^2({\bf R})$, using our formulated Feynman path integral ...
