Overview of meshfree modeling of the flowability of fresh self-compacting concrete for sustainable structures [PDF]

open access: yesE3S Web of Conferences, 2023
The flow of Bingham non-Newtonian incompressible fluids like concrete is associated with the large deformation of materials. The modeling and simulation of these fluids’ flow behavior by using conventional numerical methods.

Improved Optimization Strategy Based on Region Division for Collaborative Multi-Agent Coverage Path Planning

open access: yesSensors, 2023
In this paper, we investigate the algorithms for traversal exploration and path coverage of target regions using multiple agents, enabling the efficient deployment of a set of agents to cover a complex region.

The algorithms for the Eulerian cycle and Eulerian trail problems for a multiple graph

open access: yesМоделирование и анализ информационных систем, 2023
In this paper, we study undirected multiple graphs of any natural multiplicity $k>1$. There are edges of three types: ordinary edges, multiple edges and multi-edges. Each edge of the last two types is a union of $k$ linked edges, which connect 2 or $(k+1)

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 ...

Long directed paths in Eulerian digraphs

open access: yes, 2021
An old conjecture of Bollob s and Scott asserts that every Eulerian directed graph with average degree $d$ contains a directed cycle of length at least $ (d)$. The best known lower bound for this problem is $ (d^{1/2})$ by Huang, Ma, Shapira, Sudakov and Yuster.

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.

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).

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.
