The minimum cost flow problem with interval and fuzzy arc costs * [PDF]

open access: yes, 2011
We follow the total order for intervals and fuzzy numbers introduced by Hashemi et al. in [1] and Ghatee et al. in [2] to solve the minimum cost flow problem with either, interval or fuzzy arc costs by using its crisp model, a minimum cost flow problem

Large Benchmarks for the Minimum-Cost Flow Problem

open access: yes
Minimum cost flow instance generated at the Research Institute for Discrete Mathematics, University of Bonn. Contact: Stephan Held (held@dm.uni-bonn.de) These instances arise in VLSI placement legalization (LEGALIZATION subdir) or as linear relaxation ...

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

open access: yesAdvanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

open access: yesAdvanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Enhancing Bubble Removal in Geometry‐Optimized Electrodes

open access: yesAdvanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

A faster capacity scaling algorithm for minimum cost submodular flow

open access: yes
We describe an O(n[exp.4]h min{log U, n[exp.2] log n}) capacity scaling algorithm for the minimum cost submodular flow problem.Our algorithm modifies and extends the Edmonds-Karp capacity scaling algorithm for minimum cost flow to solve the minimum cost ...
