Disturbances in large-scale industrial systems can easily propagate through the process units and thereby adversely affect the overall process performance. In particular, oscillations in control loops are very common in industrial processes and lead to poor control performance, an excessive energy consumption and deteriorate the product quality. Identifying the propagation path of oscillations ...

In this paper, the wave propagation approach is presented to analyze the vibration and wave power reflection in FG rectangular plates based on the first order shear deformation plate theory. The wave propagation is one of the useful methods for analyzing the vibration of structures. This method gives the reflection and propagation matrices that are valuable for the analysis of mechanical energy...

Belief propagation (BP) on cyclic graphs is an efficient algorithm for computing approximate marginal probability distributions over single nodes and neighboring nodes in the graph. However, it does not prescribe a way to compute joint distributions over pairs of distant nodes in the graph. In this article, we propose two new algorithms for approximating these pairwise probabilities, based on t...

We propose that the height-angle ray vector in matrix optics should be complex, based on a geometric algebra analysis. We also propose that the ray’s 2×2 matrix operators should be right-acting, so that the matrix product succession would go with light’s left-to-right propagation. We express the propagation and refraction operators as a sum of a unit matrix and an imaginary matrix proportional ...

We propose a new method of radar imaging of underground pipes in inhomogeneous soil, which does not require a priori knowledge of the propagation velocity of electromagnetic waves in soil. In this method, three-dimensional x t -v data matrix from multiple migrated radar images with different propagation velocities using F-K migration method is composed. And we extract the hyperbolic apex and es...

Several methods for density matrix propagation in parallel computing environments are proposed and evaluated. It is demonstrated that the large communication overhead associated with each propagation step (two-sided multiplication of the density matrix by an exponential propagator and its conjugate) may be avoided and the simulation recast in a form that requires virtually no inter-thread commu...
