Roles of the Topographically-Affected Boundary Layer Low-Level Jet in the Moisture Transport Process of Nocturnal Rainstorms in Mountainous Areas around the Western Sichuan Basin

open access: yesAtmosphere, 2022
Fifteen cases were selected from May to September 2010 to 2021 to study the moisture transport of nocturnal rainstorms in mountainous areas around the western Sichuan Basin (western SCB).

The Modified Rural Postman Problem in Vehicle Route Optimization

open access: yesCommunications, 2018
The submitted paper deals with designing routes of the vehicles, which provide the transport network services. We limit our focus to such tasks, where the priority is the edge service in the transport network and the initial problem is finding an ...

Multi-directed Eulerian growing networks [PDF]

open access: yes, 2007
We introduce and analyze a model of a multi-directed Eulerian network, that is a directed and weighted network where a path exists that passes through all the edges of the network once and only once.

Digitized Stress Function-Based Feed Rate Scheduling for Prevention of Mesoscale Tool Breakage during Milling Hardened Steel

open access: yesMetals, 2021
In this article, a digitized stress function-based feed rate scheduling algorithm is formulated for the prevention of tool breakage while having an optimum material removal rate in mesoscale rough milling of hardened steel.

FEA Modeling of Soft Tissue Interaction for Active Needles With a Rotational Tip Joint

open access: yesIEEE Access, 2022
A finite element analysis (FEA) model was developed for investigating the design and the tissue interaction of actively steerable needles with a rotational tip joint in soft tissue, based on the coupled Eulerian-Lagrangian (CEL) mesh.

Warm and moist air intrusions into the winter Arctic: a Lagrangian view on the near-surface energy budgets [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
In this study, warm and moist air intrusions (WaMAIs) over the Arctic Ocean sectors of Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, Chukchi Sea, and Beaufort Sea in 40 recent winters (from 1979 to 2018) are identified from the ERA5 reanalysis ...

Geometrically nonlinear behavior of lattice domes coupled with local Eulerian instability

open access: yesCurved and Layered Structures, 2020
Structural analysis is an intricate subject when nonlinearities occur. They make the structural behavior complex and may have important consequences in the design choice as well.

Evaluation of aerosol–cloud interactions in E3SM using a Lagrangian framework [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
A Lagrangian framework is used to evaluate aerosol–cloud interactions in the U.S. Department of Energy's Energy Exascale Earth System Model (E3SM) version 1 (E3SMv1) for measurements taken at Graciosa Island in the Azores where a U.S.

Steinitz Theorems for Orthogonal Polyhedra [PDF]

open access: yes, 2009
We define a simple orthogonal polyhedron to be a three-dimensional polyhedron with the topology of a sphere in which three mutually-perpendicular edges meet at each vertex.
