UNCERTAINITY QUANTIFICATION AND STOCHASTIC MODELING

Description:

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

HIGH PERFORMANCE COMPUTING

Description:

PC integrates systems administration (including network and security knowledge) and parallel programming into a multidisciplinary field that combines digital electronics, computer architecture, system software, programming languages, algorithms 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.

Only one work per participant will be accepted, and it may be presented by more than one student and have co-authors who are tutors, teachers, or researchers of any rank. It must be presented in person by the student. To participate in the poster competition, students must follow the same process as any other work, i.e., through the OCS system, they must send:

  • An abstract (with the abstract submission deadline) according to the instructions on the website.
  • A poster in PDF format (with the full paper submission deadline).

 

The poster format is free, and as conditions, it must be A0 size, contain the conference logo, and not exceed 10Mb. The names of the students participating in the competition must be underlined to differentiate them from the tutors.

Note: Students should not submit a full paper. If they do, they should submit it to regular sessions with a different title and depth of research, to be evaluated by the corresponding session directors.
