Sequential sampling of junction trees for decomposable graphs

open access: yes, 2020
The junction-tree representation provides an attractive structural property for organizing a decomposable graph. In this study, we present a novel stochastic algorithm, which we call the junction-tree expander, for sequential sampling of junction trees ...

Analysis of Influencing Factors of a Fully Enclosed Double-Cylinder CO2 Rotor Expander for Air-Conditioner

open access: yesFrontiers in Energy Research, 2022
CO2 household air-conditioners are difficult to popularize due to their low efficiency. The use of the expander can reduce the throttling loss and increase the cooling capacity of the CO2 system.

COBOUNDARY EXPANDERS

open access: yesJournal of Topology and Analysis, 2012
We describe a higher-dimensional generalization of edge expansion from graphs to simplicial complexes, which we discuss as a type of co-isoperimetric inequality. The main point is to observe that sufficiently dense random simplicial complexes have this expander-like property with high probability, a higher-dimensional analogue of the fact that random ...
