(Preprint) AAS XX-XXX STATE-SPACE MODELING OF LARGE DOMAIN WAVE PROPAGATION SYSTEMS BY CY-PARTITIONED MATRICES

چکیده
The Cy-partitioned method to produce a reduced-order, discrete-time, state-space model for large domain wave propagation is described. The method is suitable when the output dimension is orders of magnitude higher than the number of discrete-time samples specifying the time duration of interest. The model is characterized by a relatively small dynamic component relating the inputs to a relatively small number of anchored outputs, and a large static component relating these anchored outputs to all remaining outputs. The dynamic-static partition permits identification of these models in the time domain which is not possible otherwise due to the extremely large computational power and memory requirements.

کاربرد روش معادله سهموی در تحلیل مسائل انتشار امواج داخل ساختمان
With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...
متن کاملMPI- and CUDA- implementations of modal finite difference method for P-SV wave propagation modeling
Among different discretization approaches, Finite Difference Method (FDM) is widely used for acoustic and elastic full-wave form modeling. An inevitable deficit of the technique, however, is its sever requirement to computational resources. A promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

XXX XXX XX XXX. In this paper we propose a novel approach for safety analysis based on system interface models, which are shared for both system and safety engineering. By extending interaction models on the system interface level with failure modes as well as relevant portions of the physical system to be controlled, automated support can be provided for much of the failure analysis. We partic...

A frequency-wavenumber-domain formulation is presented in this paper for calculation of the Green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. The Green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. The solution is in the frequency ...
