International Journal for Numerical Methods in Engineering, Volume 124, Issue 3, Page 714-751, 15 February 2023., 2023 Abstract In this work we present a novel monolithic Finite Element method for the hydroelastic analysis of very large floating structures (VLFS) with arbitrary shapes that is stable, energy conserving, and overcomes the need of an iterative algorithm. The new formulation enables a fully monolithic solution of the linear free‐surface flow, described by ...

Software: Practice and Experience, Volume 53, Issue 1, Page 27-52, January 2023., 2023 Abstract Ordinary differential equations can be used to describe simulation models. As such, solving these equations is an important task in the high performance computing (HPC) domain. Field programmable gate arrays (FPGAs) are a promising platform, expected to be usable as efficient accelerators for such computations.

Development of a Porous Solid Model for the Direct Reduction of Iron Ore Pellets
steel research international, Volume 93, Issue 12, December 2022., 2022 Computational fluid dynamics simulations can accurately determine the flow field of the reducing agent in the direct reduction of iron ore pellets. The external transport limitations are significant in the early stage of the reduction. The exact boundary conditions can be extracted from the flow field and later be used to derive very accurate kinetic ...

WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023 Abstraction of the formation of new vascular connections through angiogenesis. Abstract Angiogenesis, arteriogenesis, and pruning are revascularization processes essential to our natural vascular development and adaptation, as well as central players in the onset and development of pathologies such as tumoral growth and stroke recovery.

Solvable Nonlinear Evolution PDEs in Multidimensional Space [PDF]
SIGMA 2 (2006), 088, 17 pages, 2006 A class of solvable (systems of) nonlinear evolution PDEs in multidimensional space is discussed. We focus on a rotation-invariant system of PDEs of Schr\"odinger type and on a relativistically-invariant system of PDEs of Klein-Gordon type. Isochronous variants of these evolution PDEs are also considered.

Stochastic homogenization on perforated domains II – Application to nonlinear elasticity models
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 102, Issue 12, December 2022., 2022 Abstract Based on a recent work that exposed the lack of uniformly bounded W1,p→W1,p$W^{1,p}\rightarrow W^{1,p}$ extension operators on randomly perforated domains, we study stochastic homogenization of nonlinear p‐elasticity, 1

IET Power Electronics, Volume 16, Issue 1, Page 128-144, 7 January 2023., 2023 Abstract A low‐cost battery‐less solar‐powered PMDC motor using an adaptive backstepping Chebyshev neural network controller to track the desired speed for any change in irradiance and load torque is proposed in this paper. The neural network is used for approximating the variable load torque because of its approximation property.

Analysis of Schwarz methods for a hybridizable discontinuous Galerkin discretization: The many-subdomain case [PDF]
Mathematics of Computation, 2016 Schwarz methods are attractive parallel solution techniques for solving large-scale linear systems obtained from discretizations of partial differential equations (PDEs).

Efficient modelling of natural gas pipeline on electromagnetic transient simulation programs
IET Renewable Power Generation, Volume 17, Issue 1, Page 186-198, 6 January 2023., 2023 Abstract Electromagnetic transient programs (EMTPs) are widely used for simulating electromagnetic transient in power systems. With the increasing interest in integrated energy system (IES), it would be beneficial to extend the scope of EMTP‐type application to multi‐physics transients in integrated electrical and gas networks.

Sharp convergence rates of time discretization for stochastic time-fractional PDEs subject to additive space-time white noise [PDF]
Mathematics of Computation, 2017 The stochastic time-fractional equation $\partial_t \psi -\Delta\partial_t^{1-\alpha} \psi = f + \dot W$ with space-time white noise $\dot W$ is discretized in time by a backward-Euler convolution quadrature for which the sharp-order error estimate ...
