A new distributed algorithm for efficient generalized arc-consistency propagation
Autonomous Agents and Multi-Agent Systems, 2018Generalized arc-consistency propagation is predominantly used in constraint solvers to efficiently prune the search space when solving constraint satisfaction problems. Although many practical applications can be modelled as distributed constraint satisfaction problems, no distributed arc-consistency algorithms so far have considered the privacy of ...

Wave propagation in a waveguide containing restrictions with circular arc shape
The Journal of the Acoustical Society of America, 2015A multimodal method is used to analyze the wave propagation in waveguides containing restrictions (or corrugations) with circular arc shapes. This is done using a geometrical transformation which transforms the waveguide with complex geometry in the real space to a straight waveguide in the transformed space, or virtual space.

A new single-arc AC dynamic FEM model of arc propagation on ice surfaces
2013 IEEE Electrical Insulation Conference (EIC), 2013This paper presents an improved dynamic model based on the finite element method (FEM) for predicting AC critical flashover voltage (FOV) of ice-covered insulators during the melting period. The proposed model is implemented on the COMSOL Multiphysics™ FEM commercial software which is coupled with Matlab® for iterative calculation. The proposed dynamic

Propagation of vacuum arc plasma beam in a toroidal filter
IEEE Transactions on Plasma Science, 1996An analytical solution to the problem of plasma beam transport in a toroidal magnetic filter for unmagnetized ions is derived. A two-fluid model taking into account electromagnetic and pressure forces, electron-ion collisions, magnetic force line curvature, and radial dependence of centrifugal force is used. From comparison with experimental data it is

Detonation propagation in a circular arc: reactive burn modelling
Journal of Fluid Mechanics, 2017The dynamics of steady detonation propagation in a two-dimensional, high explosive circular arc geometry are examined computationally using a reactive flow model approach. The arc is surrounded by a low impedance material confiner on its inner surface, while its outer surface is surrounded either by the low impedance confiner or by a high impedance ...

Critical conditions of AC arc propagation on ice surfaces
Conference Record of the 2000 IEEE International Symposium on Electrical Insulation (Cat. No.00CH37075), 2002The critical condition of AC are propagation on ice surfaces was investigated and the arc maintenance condition was determined. It was found that the local are established along the air gap could enlarge as the air gaps enlarge with ice melting and falling down.

A parameterized arc consistency based constraint propagation algorithm
2008 International Conference on Wavelet Analysis and Pattern Recognition, 2008In order to make the constraint algorithm more efficient, the processing of constraint propagation is analyzed, and parameterized description of the arc consistency propagation depth is represented by using variable domain retraction proportion. And then an arc consistency algorithm is proposed whose propagation degree is controllable, the constraint ...

Vacuum arc plasma jet propagation in a toroidal duct
Journal of Applied Physics, 1996A two fluid magneto-hydrodynamic theory of vacuum arc plasma jet propagation in a magnetized toroidal duct is developed. The physical mechanisms of jet transverse displacement and plasma losses are analyzed and the centrifugal force on the ions is shown to play the principle role in these processes. Optimal conditions for jet propagation occur when the

Energy propagation in plasma arc welding with keyhole tracking
Energy, 2014Abstract A three dimensional mathematical model was developed to research the dynamic interaction between energy propagation and keyhole evolution in PAW (Plasma Arc Welding). Particularly, a keyhole-tracking heat source model was proposed to reflect the energy propagation in the wake of keyhole evolution, which was tracked by the VOF (Volume of ...
