Corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (RC) structures deterioration in chloride-contaminated environments. As a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. The corrosion propagation phase is a ...

Key Performance Indicator (KPI) is a type of performance measurement that evaluates the success of an organization or a partial activity in which it engages. If during the running process instance the monitoring results show that the KPIs do not reach their target values, then the influential factors should be identified, and the appropriate adaptation strategies should be performed to prevent ...

The aeroacoustic performance of an adaptive inlet of a turbo-fan engine is numerically investigated in this paper. The sound intensity and directivity of the fan noise propagation to the far-field, and the sound level at lateral reference points are investigated. The investigation is performed for three Helmholtz numbers, with the influence of the mean flow included, for a single duct mode (8,1...

We introduce a preconditioner for the solution of the Bidomain system governing the propagation of action potentials in the myocardial tissue. The Bidomain model is a degenerate parabolic set of nonlinear reaction-diffusion equations. The nonlinear term describes the ion flux at the cellular level. The degenerate nature of the problem results in a severe ill conditioning of its discretization. ...

OBJECTIVES M cells have been described in many mammalian species. They are thought to be relevant for the genesis of long QT intervals, afterdepolarizations and for dispersion in action potential duration and in repolarization time. Their role in the human heart is subject to debate. METHODS We simulated action potential propagation in a strand of transversally oriented myocytes running from ...

Many problems in computer science can be represented by a graph and reducedto a graph clustering or k-way partitioning problem. In the classical definition,a graph consists of nodes and edges which usually connect exactly two nodes.Hypergraphs are a generalization of graphs, where every edge can connect anarbitrary number of nodes. Recent results suggest that some problems i...

| Given a problem, a case-based reasoning (CBR) system will search its case memory and use the stored cases to nd the solution, possibly modifying retrieved cases to adapt to the required input speciications. In this paper we introduce a neural network architecture for eecient case-based reasoning. We show how a rigorous Bayesian probability propagation algorithm can be implemented as a feedfor...

Herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) are members of the Herpesviridae family. About 40% to 80% of the world populations are infected with HSV and its prevalence is high in Iran. The high prevalence of this virus in the community and the ability of the virus in causing fatal diseases among immunocompromised patients, have encouraged studies to be performed on HSV and suitable cell ...

Two-dimensional Euler equations have been solved on an unstructured grid. An upwind finite volume scheme, based on Roe's flux difference splitting method, is used to discretize the equations. Using advancing front method, an initial Delaunay triangulation has been made. The adaptation procedure involves mesh enrichment coarsening in regions of flow with high low gradients of flow properties, ac...
