Study of a Square Single-Phase Natural Circulation Loop Using the Lattice Boltzmann Method

open access: yesApplied Mechanics, 2023
Natural circulation loops are thermohydraulic circuits used to transport heat from a source to a sink in the absence of a pump, using the forces induced by the thermal expansion of a working fluid to circulate it.

Integrated Cost-Analysis Approach for Seismic and Thermal Improvement of Masonry Building Façades

open access: yesBuildings, 2020
The combination of structural and thermal efficiency is a new frontier in civil engineering. Indeed, the retrofitting strategies should optimize costs and technical solutions from these two points of view.

Mesoscale Structure in the Solar Wind

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Structures in the solar wind result from two basic mechanisms: structures injected or imposed directly by the Sun, and structures formed through processing en route as the solar wind advects outward and fills the heliosphere. On the largest scales, solar

Stochastic finite elements: Where is the physics? [PDF]

open access: yesTheoretical and Applied Mechanics, 2011
The micromechanics based on the Hill-Mandel condition indicates that the majority of stochastic finite element methods hinge on random field (RF) models of material properties (such as Hooke’s law) having no physical content, or even at odds with ...

Quantum Effects on the Mesoscale

open access: yesParticles, 2020
In different areas of mechanics, highly non-equilibrium processes are accompanied by self-organization of various type turbulent structures and localized inhomogeneities at intermediate scale between macro and micro levels.

Simulating Atmospheric Characteristics and Daytime Astronomical Seeing Using Weather Research and Forecasting Model

open access: yesApplied Sciences, 2023
The present study is aimed at the development of a novel empirical base for application to ground-based astronomical telescopes. A Weather Research and Forecasting (WRF) model is used for description of atmospheric flow structure with a high spatial ...

Mesoscale Laser 3D Printing

open access: yesOptics Express, 2018
3D meso-scale structures that can reach up to centimeters in overall size but retain micro- or nano-features, proved to be promising in various science fields ranging from micro-mechanical metamaterials to photonics and bio-medical scaffolds. In this work we present synchronization of the linear and galvano scanners for efficient femtosecond 3D optical

Sugar, Gravel, Fish, and Flowers: Dependence of Mesoscale Patterns of Trade‐Wind Clouds on Environmental Conditions

open access: yesGeophysical Research Letters, 2020
Trade‐wind clouds exhibit a large diversity of spatial organizations at the mesoscale. Over the tropical western Atlantic, a recent study has visually identified four prominent mesoscale patterns of shallow convection, referred to as flowers, fish ...

Monitoring Mesoscale to Submesoscale Processes in Large Lakes with Sentinel-1 SAR Imagery: The Case of Lake Geneva

open access: yesRemote Sensing, 2022
As in oceans, large-scale coherent circulations such as gyres and eddies are ubiquitous features in large lakes that are subject to the Coriolis force.

Emergence of scale-free close-knit friendship structure in online social networks [PDF]

open access: yes, 2012
Despite the structural properties of online social networks have attracted much attention, the properties of the close-knit friendship structures remain an important question.
