Evaluation of Municipal Water Distribution System Reliability Using Minimum Cut-set Method

open access: yesJournal of King Saud University: Engineering Sciences, 2005
Reliability analysis of water distribution systems is a complex task, as it requires both definition and calculation of reliability measures. In this paper, a methodology for evaluating water distribution system reliability is developed and demonstrated ...

Two kinds of conditional connectivity of hypercubes

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
A subset [Formula: see text] is called an h-extra r-component cut of G if G – F is disconnected and there are at least r components, each component has at least h + 1 vertices.

4-tangrams are 4-avoidable [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
A tangram is a word in which every letter occurs an even number of times. Thus it can be cut into parts that can be arranged into two identical words. The \emph{cut number} of a tangram is the minimum number of required cuts in this process.

Sufficient conditions for triangle-free graphs to be super-$λ'$ [PDF]

open access: yesTransactions on Combinatorics, 2018
An edge-cut $F$ of a connected graph $G$ is called a‎ ‎restricted edge-cut if $G-F$ contains no isolated vertices‎. ‎The minimum cardinality of all restricted edge-cuts‎ ‎is called the restricted edge-connectivity $λ'(G)$ of $G$‎. ‎A graph $G$ is said to

Extremal Dependence and Community-Structured Risk Propagation in Complex Social Information Networks

open access: yesMathematics
Extreme opinion propagation in social information networks often appears as a low-frequency but high-impact process, in which abnormal activity becomes synchronized across structurally related users or communities during crisis periods.

Shared-Memory Exact Minimum Cuts [PDF]

open access: yes2019 IEEE International Parallel and Distributed Processing Symposium (IPDPS), 2019
The minimum cut problem for an undirected edge-weighted graph asks us to divide its set of nodes into two blocks while minimizing the weight sum of the cut edges. In this paper, we engineer the fastest known exact algorithm for the problem. State-of-the-art algorithms like the algorithm of Padberg and Rinaldi or the algorithm of Nagamochi, Ono and ...

Blocking Detection Based on Synoptic Filters

open access: yesAdvances in Meteorology, 2011
The Tibaldi-Molteni blocking index is supplemented by additional filter criteria to eliminate cut-off lows and subsynoptic structures. We introduce three blocking filters and analyse their sensitivities: (i) a quantile filter requiring a minimum ...

Partitions of networks that are robust to vertex permutation dynamics

open access: yesSpecial Matrices, 2015
Minimum disconnecting cuts of connected graphs provide fundamental information about the connectivity structure of the graph. Spectral methods are well-known as stable and efficient means of finding good solutions to the balanced minimum cut problem.

Optimization of cnc operating parameters to minimize surface roughness of Pinus sylvestris using integrated artificial neural network and genetic algorithm

open access: yesMaderas: Ciencia y Tecnología, 2021
The surface roughness of wood is affected by the processing conditions and the material structure. So, optimization of operation parameters is very crucial to have minimum surface roughness. In this study, modeling and optimization of surface roughness (
