UNCERTAINITY QUANTIFICATION AND STOCHASTIC MODELING

  • The rational treatment of uncertainties and their effects in computational mechanics receives, particularly in recent years, increasing attention. Loading conditions, material properties and geometry show, in some cases, considerable variations. Observations and measurements of physical processes as well as parameters clearly exhibit random characteristics. Hence, statistical and probabilistic procedures provide a sound framework for a rational basis for processing these uncertainties. In addition to parameter uncertainties, model uncertainties play also a focal role in modern structural mechanics. In reality, neither the true model nor the model parameters are deterministically known. It is for these uncertainties that the assumption that an ever finer discretization leads consequently to an increase in accuracy is a myth. In this context, the aspects of model validation and verification respectively are also addressed. In this mini symposium, conceptual and computational aspects of uncertainty processing and assessment will be discussed.

Main contents:

  • Uncertainty Quantification
  • Stocastic Modeling
  • Probabilistic methods in mechanics
  • Dynamics of mechanical systems

MULTIPHASE FLOW AND TRANSPORT IN POROUS MEDIA AND MICROSCALE

The session is aimed at the presentation of those works that involve the resolution of fluid flow and / or transport in non-homogeneous media or systems. Generally, these non-homogeneities are given on a micrometric scale, and as examples we can cite porous media, microdroplets, microemulsions or heterogeneities by accumulation of electrical charges in solution, among others. Two of the intrinsic characteristics of the mentioned physical systems are the flow regimes of laminar fluids or very low Reynolds number, and in the case of transport, the high number of Pèclet. Among the applications that we understand a priori can integrate this session we can include: microfluidics on paper, microdrops and microemulsions studies, transport in artificial biological media, transport of biomolecules in micro and nanostructured spaces and lubrication flow, among others.

high performance computing

HPC integrates systems administration (including network and security knowledge) and parallel programming into a multidisciplinary field that combines digital electronicscomputer architecturesystem softwareprogramming languagesalgorithms and computational techniques. HPC technologies are the tools and systems used to implement and create high performance computing systems. Recently HPC systems have shifted from supercomputing to computing clusters and grids. Because of the need of networking in clusters and grids, High Performance Computing Technologies are being promoted by the use of a collapsed network backbone, because the collapsed backbone architecture is simple to troubleshoot and upgrades can be applied to a single router as opposed to multiple ones.

tEACHING OF NUMERICAL METHODS

The use of Numerical Methods in the different branches of Exact Sciences and Engineering is a fact that has been deepened in recent years and formally incorporated into most of the curricula of the new curricula. The teaching of these methods and their applications have been incorporated in different contexts, with different degrees of interaction between the subjects of the different curricular blocks: basic sciences, basic and applied technologies. Likewise, there is a variety of interest in the basic or applied character and with a great breadth in the perspective of approach in the transfer to the student of the concept of Numerical Method. Since ENIEF 2011, and on an ongoing basis, this session aims to generate a discussion space on the Teaching of Numerical Methods and their Applications in undergraduate and graduate courses. Works that address both the design of the curricula associated with the Teaching of Numerical Methods in particular and / or their use in related subjects, as well as innovative teaching experiences that involve the use of Numerical Methods as an analysis tool, may be presented
