Development of Improved Rheometric Tools and their Application on the Non-Newtonian Rheology of Polymeric Fluids

TL;DR: In this paper, the normal force and pressure of polymers are studied with improved constructions for rheometers via the FT, where time-dependent data from oscillatory shear and capillary flows is analysed.

An interior point method in function space for the efficient solution of state constrained optimal control problems

TL;DR: The introduction of a pointwise damping step leads to a very efficient method, as verified by numerical experiments, on constructing a practical path-following algorithm in function space.

The tensor rank of tensor product of two three-qubit W states is eight

TL;DR: The tensor rank of tensor product of two three-qubit W states is not less than eight as mentioned in this paper, which is the upper bound of the tensor ranking of many three-quantity W states.

Modified Sparse Approximate Inverses (MSPAI) for Parallel Preconditioning

TL;DR: The objective is to extend SPAI in order to satisfy certain additional constraints, the so-called probing constraints, and the resulting preconditioner should act in an optimal way on these probing subspaces.

A mapping framework for guided design space exploration of heterogeneous MP-SoCs

TL;DR: It is shown how the behavior of heterogeneous MP-SoCs systems can be analyzed without the need for time-consuming implementations of simulation models, enabling fast evaluation and modification of a given system at a very early design stage allowing efficient pruning of the design space.
