Coupling Algorithms for Partitioned Multi-Physics Simulations

Partitioned coupling approaches are an important tool in order to achieve a decent time-to-solution for multi-physics problems with more than two physical fields or changing combinations of fields. We study different approaches to deduce coupling schemes for partitioned multi-physics scenarios, by means of a simple, but yet challenging fluid-structure-fluid model problem. To our knowledge, this...

Conformal Anomaly and Large Scale Gravitational Coupling

We present a model in which the breackdown of conformal symmetry of a quantum stress-tensor due to the trace anomaly is related to a cosmological effect in a gravitational model. This is done by characterizing the traceless part of the quantum stress-tensor in terms of the stress-tensor of a conformal invariant classical scalar field. We introduce a conformal frame in which the anomalous trace ...

Low-Cost Non-Intrusive Debugging Strategies for Distributed Parallel Programs

Debugging is an important and challenging component of the software development cycle. The utilization of proper tools that help trace execution, inspect variable values, do postmortem analysis, dynamically attach to running processes, among other tasks can greatly increase programmer productivity by reducing the time to understand incorrect behavior. It is well known that many more hours are s...

Tans-scale Coupling in Multi-scale Simulation

The physics and mathematics involved in modeling of components of cardiovascular system is very different from that in many other engineering problems. For example, the blood flows in vessels with a deformable boundary (the viscoelastic walls of the vessel) that may require modeling of fluid and tissue interaction and for smaller arteries, the non-Newtonian nature of the blood requires special ...

Multi-scale Hierarchical Segmentation

In the absence of a priori information on scales of interest vision systems should initially process in a scale invariant manner. The fact that any signal can only be sampled discretely further constrains the initial processing. The paper argues that a representation satisfying these requirements is an hierarchical segmentation of scalespace. An algorithm is presented to compute such representa...
