A Lagrangian–Eulerian compressible model for the trans-critical path of near-critical fluids

International Journal of Multiphase Flow, 2014
Abstract The main objective of the present work is to model the trans-critical path from supercritical to subcritical states near the critical point. The model is based on full compressible sets of equations. The pressure, temperature and density fields are determined in a Lagrangian form through the divergences of velocity and heat flux and advected

Hamiltonian and Eulerian Paths [PDF]

, 1983
March 14. Hamiltonian and Eulerian paths and cycles come under the general heading of “de Bruijn sequences”. The specific terms “Hamiltonian” and “Eulerian” are somewhat better known; hence this chapter has been named after them rather than de Bruijn.

INT-react: An O(E) Path Planner for Resilient Network-Wide Telemetry Over Megascale Networks

IEEE International Conference on Network Protocols, 2022
In-band network telemetry (INT) delivers high-precision network monitoring by collecting device-internal states entirely on the data plane. For rapid congestion awareness and network troubleshooting, it is necessary to conduct network-wide telemetry by ...

Weld line recognition and path planning with spherical tank inspection robots

J. Field Robotics, 2021
Periodic inspections are required for the safe operation of large pressure vessels such as spherical tanks. Inspection robots have been applied in large pressure vessels due to their low cost and high efficiency.

Two Arc-Disjoint Paths in Eulerian Digraphs

SIAM Journal on Discrete Mathematics, 1995
A polynomial time algorithm is given for the following decision problem: Instance: An Eulerian digraph \(D\) and two pairs \(\{x_1,x_2\},\{y_1,y_2\}\) of its vertices. Question: Is there a choice of \(h,i,j,k\) with \(\{h,i\}=\{j,k\}=\{1,2\}\) such that there are arc-disjoint \(x_hy_j\) and \(x_iy_k\) paths?

Evolutionary Computation for Solving Path Planning of an Autonomous Surface Vehicle Using Eulerian Graphs

IEEE Congress on Evolutionary Computation, 2018
An evolutionary-based path planning is designed for an Autonomous Surface Vehicle (ASV) used in environmental monitoring tasks. The main objective is that the ASV covers the maximum area of a mass of water like the Ypacarai Lake while taking water ...

On dual Eulerian paths and circuits in plane graphs

1988., IEEE International Symposium on Circuits and Systems, 2003
Given a nonseparable plane graph G, a path or circuit is called dual if it is also a path or circuit, respectively, in the geometric dual of G. Motivated by a layout design problem of CMOS integrated circuits, the authors consider some problems of partitioning the edges of G into the minimum number of dual paths or circuits.

The Tropical Atmospheric Conveyor Belt: A Coupled Eulerian‐Lagrangian Analysis of the Large‐Scale Tropical Circulation

Geophysical Research Letters, 2020
The Hadley circulation is a key element of the climate system. It is traditionally defined as the zonally averaged meridional circulation in the tropics, therefore treated as a zonally symmetric phenomenon.
