A closed-form solution for the barrier properties of randomly oriented high aspect ratio flake composites
(2019)We derive closed-form solutions for the barrier factor of flake-filled composites, in which the flakes are randomly placed and oriented, with the orientation angles uniformly distributed in an interval [−ɛ, +ɛ], 0 < ɛ < ... -
Collagen fibril diameter distribution affects permeability of ligament tissue: A computational study on healthy and injured tissues
(2020)Background and objective In a vascular or hypovascular tissues, elements required for maintaining tissue functions are recruited through diffusion, which is highly related with the permeability of the extracellular matrix ... -
Column generation for scheduling shipments within a supply chain network with the minimum number of vehicles
(2014)We consider the problem of scheduling a set of shipments between different nodes of a supply chain network. Each shipment has a fixed departure time, as well as an origin and a destination node, which, combined, determine ... -
Flow rate measurements of binary gas mixtures through long trapezoidal microchannels
(2012)The flow rate of two noble gas mixtures, namely He/Ar and He/Kr, is measured through a microsystem containing 400 long trapezoidal microchannels placed in parallel configuration. Each microchannel has a trapezoidal cross ... -
A general scaling for the barrier factor of composites containing thin layered flakes of rectangular, circular and hexagonal shape
(2020)We propose a general scaling which allows for the results of 3D mass transfer computations in layered flake composites containing square, circular or hexagonal flakes to collapse on a single master curve. We show that the ... -
Mixed integer biobjective quadratic programming for maximum-value minimum-variability fleet availability of a unit of mission aircraft
(2017)We consider the FMP problem encountered in the Hellenic Air Force (HAF), that is, the problem of issuing individual flight and maintenance plans for a group of aircraft comprising a unit, so as to maximize the fleet ... -
Orientational randomness and its influence on the barrier properties of flake-filled composite films
(2017)This direct numerical study investigated the effect of orientational randomness on the barrier properties of flake-filled composites. Over 2500 simulations have been conducted in two-dimensional, doubly periodic unit cells, ...
