Techniques for Efficient Constraint Propagation [Elektronisk resurs]

open access: yes, 2008
This thesis explores three new techniques for increasing the efficiency of constraint propagation: support for incremental propagation, improved representation of constraints, and abstractions to simplify propagation.  Support for incremental propagation

The beam propagation method used for the design of an integrated optical coupler [PDF]

open access: yes, 2007
The beam propagation method (BPM) used for the design of an integrated optical (IO) coupler was proposed in this paper. A modal of the IO coupler was set up in BeamPROP software that is based on the BPM, and then the modes and the bi-directional ...

Wave Propagation in Granular Materials [PDF]

open access: yes, 2005
Wave propagation is a fundamental property of all physical systems. The wave speed is directly related to the compressibility of the system and determines the rate at which local disturbances are propagated into the bulk of the material.

Short and long supports for constraint propagation [PDF]

open access: yes, 2013
Special-purpose constraint propagation algorithms frequently make implicit use of short supports -- by examining a subset of the variables, they can infer support (a justification that a variable-value pair may still form part of an assignment that ...

Propagation-induced entanglement revival

open access: yes, 2021
The practical implementation of free-space quantum information tasks requires entanglement to be sustained over long distances and in the presence of turbulent and noisy environments. The transverse position-momentum entanglement of photon pairs produced

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]

open access: yes, 2007
We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Principles of Creation of Local Network for Lightning Discharge Observations on Active Volcanoes of Kamchatka Peninsula [PDF]

open access: yesE3S Web of Conferences, 2019
To investigate the thunderstorm activity according to electromagnetic radiation recorded data, it is necessary to create a local network which will be located near the Klyuchevskaya Sopka, Shiveluch and Tolbachik volcanoes.

Design and Simulation of Stellar Occultation Infrared Band Constellation

open access: yesRemote Sensing, 2022
This study provides an in-depth analysis of the characteristics of stellar occultation events. Using 10 target star sources, the influence of orbital elements on the number, duration, and distribution of stellar occultation events was simulated and ...
