Multipath Routing plays an important role in communication networks. Multiple disjoint paths can increase the effective bandwidth between pairs of vertices, avoid congestion in a network and reduce the probability of dropped packets. In this paper, we built mathematical models for arc-disjoint paths problem and vertex-disjoint paths problem respectively, and then proposed polynomial algorithms for...
This paper presents a numerical solution to describe growth factor-receptor binding under flow through hollow fibers of a bioreactor. The multi-physics of fluid flow, the kinetics of fibroblast growth factor (FGF-2) binding to its receptor (FGFR) and heparan sulfate proteoglycan (HSPG) and FGF-2 mass transport is modeled by a set of coupled nonlinear partial differential equations (PDEs) and coupled...
In this paper, a multi-depot vehicle routing problem with weight-related cost (MDVRPWRC) is discussed. It is an extension of the classical multi-depot vehicle routing problem (MDVRP) by treating the vehicle load, i.e. the total weight of freight in a vehicle, as a variable in the objective of model. The corresponding costs incurred by the vehicle load are considered in the objective function when...
To analyze the nuclei distributed in the glomeruli of the renal biopsy images automatically, the problem of missing or wrong extraction of them caused by the complex characteristics of the renal biopsy images must be solved. This paper introduces a dynamic thresholding method using eigenvalue feedback strategy based on multi-channel information. Firstly, the nonlinear thresholding surface adjusted...
