Isogeometric analysis of THM coupled processes in ground freezing
(Journal article; Peer reviewed, 2017)An isogeometric analysis (IGA) based numerical model is presented for simulation of thermo-hydro-mechanically (THM) coupled processes in ground freezing. The momentum, mass and energy conservation equations are derived ... -
Isogeometric analysis using LR B-splines
(Journal article; Peer reviewed, 2014)The recently proposed locally refined B-splines, denoted LR B-splines, by Dokken et al. (2013) [6] may have the potential to be a framework for isogeometric analysis to enable future interoperable computer aided design and ... -
Isogeometric boundary element method for acoustic scattering by a submarine
(Journal article; Peer reviewed, 2019)Isogeometric analysis with the boundary element method (IGABEM) has recently gained interest. In this paper, the approximability of IGABEM on 3D acoustic scattering problems will be investigated and a new improved BeTSSi ... -
Isogeometric collocation for implicit dynamics of three-dimensional beams undergoing finite motions
(Journal article; Peer reviewed, 2019)We propose a novel approach to the implicit dynamics of shear-deformable geometrically exact beams, based on the isogeometric collocation method combined with the Newmark time integration scheme extended to the rotation ... -
Isogeometric collocation for the Reissner–Mindlin shell problem
(Journal article; Peer reviewed, 2017)We present an isogeometric collocation formulation for the Reissner-Mindlin shell problem. After recalling the necessary basics on differential geometry and the shell governing equations, we show that the standard approach ... -
Isogeometric divergence-conforming variational multiscale formulation of incompressible turbulent flows
(Journal article, 2016)A new residual-based variational multiscale (RBVMS) formulation for incompressible turbulent flows is proposed that is suitable for discretization using divergence-conforming B-splines. The proposed methodology results in ... -
An isogeometric finite element-boundary element approach for the vibration analysis of submerged thin-walled structures
(Peer reviewed; Journal article, 2021)In this paper, the isogeometric formulations of the finite element and boundary element methods are applied to the dynamic analysis of thin-walled structures submerged in an infinite, inviscid, and incompressible fluid ... -
Isogeometric Kirchhoff-Love shell formulation for elasto-plasticity
(Journal article; Peer reviewed, 2018)An isogeometric thin shell formulation allowing for large-strain plastic deformation is presented. A stress-based approach is adopted, which means that the constitutive equations are evaluated at different integration ... -
Isogeometric methods for CFD and FSI-simulation of flow around turbine blades
(Journal article; Peer reviewed, 2015)Coupled fluid-structure interaction simulations of wind turbines have traditionally been considered computationally too expensive to carry out. However, more powerful computers and better solution techniques based on ... -
Isogeometric Modeling and Experimental Investigation of Moving-Domain Bridge Aerodynamics
(Journal article; Peer reviewed, 2019)Computational fluid dynamics (CFD) and fluid–structure interaction (FSI) are growing disciplines in the aeroelastic analysis and design of long-span bridges, which, with their bluff body characteristics, offer major ... -
Isolated and combined effects of high-intensity interval training and time-restricted eating on glycaemic control in reproductive-aged women with overweight or obesity: Study protocol for a four-armed randomised controlled trial
(Peer reviewed; Journal article, 2021)Introduction Overweight and obesity in reproductive aged women is a global problem due to the increased risk of subfertility, pregnancy complications and cardiometabolic diseases. High-intensity interval training and ... -
Isolated Handwritten Character Recognition of Ancient Hebrew Manuscripts
(Journal article, 2022)Character recognition is widely considered an essential factor in preserving and digitizing historical handwritten documents. While it has shown a significant impact, the character recognition of historical handwritten ... -
Isolated High-Frequency Link PFC Rectifier With High Step-Down Factor and Reduced Energy Circulation
(Peer reviewed; Journal article, 2022)This article presents an isolated single-stage ac–dc high-frequency link full-bridge cycloconverter (HFLC) with high conversion ratio. Despite certain advantages, such topologies gen- erally suffer from transformer leakage ... -
Isolation and comparison of neural stem cells from the adult rat brain and spinal cord canonical neurogenic niches
(Peer reviewed; Journal article, 2022)Here, we present a unified protocol for the extraction, culture, and basic characterization of rat neural stem cells (NSCs) from all three canonical neurogenic niches in the brain and spinal cord. We describe tissue ... -
