Comparison of spatial downscaling methods of general circulation model results to study climate variability during the Last Glacial Maximum [PDF]

Geoscientific Model Development, 2018
The extent to which climate conditions influenced the spatial distribution of hominin populations in the past is highly debated. General circulation models (GCMs) and archaeological data have been used to address this issue.

A Macro‐Model for Simulating Gusset Plate Buckling in Buckling‐Restrained Braced Frame Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT 2D models, which are conventionally employed for the seismic performance assessment of buckling‐restrained braced frame (BRBF) buildings, are incapable of simulating the out‐of‐plane buckling of gusset plates. This study presents a novel 3D macro‐modelling approach capable of capturing the out‐of‐plane buckling of gusset plates in BRBFs.

Description and Convergence Order Analysis of the Finite Element‐Volume Spatial Discretization Method

International Journal for Numerical Methods in Fluids, EarlyView.
This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

Application of low-order potential solutions to higher-order vertical traction boundary problems in an elastic half-space [PDF]

Royal Society Open Science, 2018
New solutions of potential functions for the bilinear vertical traction boundary condition are derived and presented. The discretization and interpolation of higher-order tractions and the superposition of the bilinear solutions provide a method of ...

Fluorescence as a tracer of the susceptibility of dissolved organic matter to photodegradation in the Arctic Ocean

Limnology and Oceanography, EarlyView.
Abstract The Arctic Ocean exports a large amount of terrestrial dissolved organic matter (DOM) to the Nordic seas. With climate change, the supply of terrestrial DOM from the Arctic Ocean will increase while less sea ice might lead to an increased loss of terrestrial DOM due to photodegradation.

Diffusion probabilistic generative models for accelerated, in‐NICU permanent magnet neonatal MRI

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Magnetic Resonance Imaging (MRI) enables non‐invasive assessment of brain abnormalities during early life development. Permanent magnet scanners operating in the neonatal intensive care unit (NICU) facilitate MRI of sick infants, but have long scan times due to lower signal‐to‐noise ratios (SNR) and limited receive coils.

Numerical Study on the Thermo‐Hydro‐Mechanical Behavior of Energy Micropiles in Hypoplastic Soft Clay Under Cyclic Thermal Loading

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Coupled nonlinear thermo‐hydro‐mechanical finite element simulations were carried out to investigate the behavior of energy micropiles subjected to thermal loading cycles. Two kinds of problems were analyzed: The case of an isolated micropile, for which comparison with previous research on medium‐size isolated energy pile is provided, and the ...

Climatic Specific Energy Rating Analysis of Outdoor PV Field Data

Progress in Photovoltaics: Research and Applications, EarlyView.
The study evaluates the Climatic Specific Energy Rating (CSER) of Photovoltaic device according to IEC 61853 standard series. It explores the use of long‐term PV outdoor field data in order to understand how the length and seasonality of the data acquisition period affects the reliability of the CSER parameter. It provides important insights for the PV
