In addition, a port-Hamiltonian representation of the resulting passive model is developed. Focusing on the isothermal case, we propose a suitable storage function which permits to analyze passivity of the SMA model and to quantify energy dissipation due to hysteresis. Such a model represents an effective control-oriented tool to describe the hysteretic dynamics of SMAs, but its highly complex structure makes it difficult to analyze fundamental properties such as energetic consistency, i.e., passivity. In this work we investigate passivity of the Müller-Achenbach-Seelecke Model for shape memory alloy (SMA) wires. As a POD-of-PODs method, the HAPOD can be parallelized and further accelerated by user supplied SVD implementations. Typically, an entry point on the skullcap is determined from which the target region inside the brain is approached. The HAPOD is an algorithm to compute the POD (left singular vectors, and singular values of a matrix) hierarchically for (column-wise partitioned) large-scale matrices, allowing to balance accuracy with performance. Stereotactic neurosurgery requires careful a priori design and planning of cannula trajectories.

#Mathmod 2018 series
9th Vienna International Conference on Mathematical Modelling (MATHMOD 2018), Vienna. The MATHMOD 2018 continues the conference series MATHMOD Vienna in February 2018. Model order reduction (MOR) has proven to be a powerful methodology to reduce the costs and is well established for linear problems. Waves Wavalets and Fractals-Advanced Analysis (Until 2018). Corrections of more than 30 bugs related to MathMod allocated resources. Add new scripts to generate math models with chained patterns (Chained Cylinder/Sinusoid). Add option to export OBJ files with vertex colours. The computational costs are a multiple of the costs of anisotropic models in brute force methods according to the components used in the multiscale formulation, compare with Hollaus and Schöberl (2017). Change-log for MathMod-8.0 () Add new tool for scripts selection on one or multiple JSON scripts fields.
Although the multiscale finite element method (MSFEM) can be exploited to simulate eddy currents in laminted iron more efficiently the complexity of the problems are still too large to solve them conveniently. However, the large systems to be solved result in high computational costs, i.e. The simulation of the eddy currents in electrical devices with the finite element method (FEM) is satisfactory.
