Local ionospheric modelling of GPS code and carrier phase observations
(Peer reviewed; Journal article, 2008)A limiting factor for successful ambiguity resolution in precise GPS positioning is the existence of un-modelled ionospheric errors in both the carrier phase and the pseudorange measurements. In this study, the ionospheric ... -
Local loss coefficients inside air cavity of ventilated pitched roofs
(Journal article; Peer reviewed, 2018)Pitched roofs with a ventilated air cavity to avoid snow melt and ensure dry conditions beneath the roofing are a widely used construction in northern parts of Europe and America. The purpose of this study has been to ... -
Local mechanical properties and precipitation inhomogeneity in large-grained Al–Mg–Si alloy
(Peer reviewed; Journal article, 2022)Al–Mg–Si (6xxx series) alloys show excellent mechanical properties due to the precipitates formed during heat treatment. However, heat treatment of these alloys results in a soft precipitation free zone (PFZ) close to grain ... -
Local Ocean Wave Field Estimation Using A Deep Generative Model of Wave Buoys
(Journal article, 2023)Estimating oceanic wave fields from sparse observations has been a long-standing challenge in oceanography and an important environmental metric desired for maritime operations. The requirement for frequent real-time updates ... -
Local Postoperative Graft Inflammation in Pancreas Transplant Patients With Early Graft Thrombosis
(Peer reviewed; Journal article, 2023)Background. Graft thrombosis is the main cause of early graft loss following pancreas transplantation, and is more frequent in pancreas transplant alone (PTA) compared with simultaneous pancreas-kidney (SPK) recipients. ... -
Local projections of layer Vb-to-Va are more prominent in lateral than in medial entorhinal cortex
(Peer reviewed; Journal article, 2021)The entorhinal cortex, in particular neurons in layer V, allegedly mediate transfer of information from the hippocampus to the neocortex, underlying long-term memory. Recently, this circuit has been shown to comprise a ... -
Local statistics of immiscible and incompressible two-phase flow in porous media
(Peer reviewed; Journal article, 2023)We consider immiscible and incompressible two-phase flow in porous media under steady-state conditions using a dynamic pore network model. We focus on the fluctuations in a Representative Elementary Area (REA), with the ... -
Local strain energy based fatigue assessment of cruciform welded joints: experimental data analysis and influence of hot-dip galvanization
(Journal article; Peer reviewed, 2018)Performing the fatigue assessment of a welded joint using the Notch Stress Intensity Factors [1] presents two major challenges. The first is the necessity of a precise reconstruction of the stress field around the notch ... -
Local strain energy density for the fatigue assessment of hot dip galvanized welded joints: Some recent outcomes
(Journal article; Peer reviewed, 2017)Since in literature only data about the effect of the hot-dip galvanizing coating on fatigue behavior of unnotched specimens are available, whereas very few for notched components and none for welded joints, the aim of ... -
Local strain energy density for the fracture assessment of polyurethane specimens weakened by notches of different shape
(Journal article; Peer reviewed, 2017)Recent studies on local stress fields in proximity of crack and notch tips have shown that Strain Energy Density (SED), averaged in a circular control volume surrounding the point of stress singularities, represents a ... -
Local strain energy density to assess the multiaxial fatigue strength of titanium alloys
(Peer reviewed; Journal article, 2016)The present paper investigates the multiaxial fatigue strength of sharp V-notched components made of titanium grade 5 alloy (Ti-6Al-4V). Axisymmetric notched specimens have been tested under combined tension and torsion ... -
Local structural coupling of A- and B-site disorder in perovskite bismuth-based piezoelectrics
(Journal article; Peer reviewed, 2019)The local and average structure of (1-x)Bi0.5K0.5TiO3-xBiFeO3 (BKT-xBFO, x = 0.25 and 0.5) solid solutions are studied by synchrotron X-ray total scattering from ambient to 773 K. Pair distribution functions (PDFs) demonstrate ... -
Local structure of Ca2+ alginate hydrogels gelled via competitive ligand exchange and measured by small angle X-ray scattering
(Journal article; Peer reviewed, 2019)Alginates, being linear anionic co-polymers of 1,4-linked residues β-d-ManA (M) and α-l-GulA (G), are widely applied as hydrogel biomaterials due to their favourable in vivo biocompatibility and convenient ionic crosslinking. ... -
Local Structure of Disordered Bi0.5K0.5TiO3 Investigated by Pair Distribution Function Analysis and First-Principles Calculations
(Journal article; Peer reviewed, 2017)We investigate A-site cation ordering in the ferroelectric perovskite Bi0.5K0.5TiO3 (BKT) by density functional theory (DFT) calculations and synchrotron X-ray total scattering. Using BKT as a prototypical lead-free ... -
Local surface crystal structure fluctuation on Li, Na and Mg metal anodes
(Peer reviewed; Journal article, 2022)Dendrite formation occurs on Li, Na, and Mg metal anodes in rechargeable batteries, and is a safety challenge, as well as a limiting factor for increasing energy- and power density. However, the behaviour of the dendrites ... -
Local thermodynamic description of isothermal single-phase flow in porous media
(Journal article; Peer reviewed, 2022)Darcy's law for porous media transport is given a new local thermodynamic basis in terms of the grand potential of confined fluids. The local effective pressure gradient is determined using non-equilibrium molecular dynamics, ... -
