In this paper we present a new diagonal balancing technique for regular matrix pencils λB − A, which aims at reducing the sensitivity of the corresponding generalized eigenvalues. It is inspired from the balancing technique of a square matrix A and has a comparable complexity. Upon convergence, the diagonally scaled pencil has row and column norms that are balanced in a precise sense. We also s...

in this research, the charged system search (css) and enhanced charged system search (ecss) algorithm are used to obtain the optimum design of irregular grillage systems with different spacing and various boundary conditions. the cross-sectional properties of the beams are selected as the design variables and the weight of structure is used as the objective function. the displacement limitation...

Pore network modeling uses a network of pores connected by throats to model the void space of a porous medium and tries to predict its various characteristics during multiphase flow of various fluids. In most cases, a non-realistic regular lattice of pores is used to model the characteristics of a porous medium. Although some methodologies for extracting geologically realistic irregular net...

In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as high frequency irregular wa...

In this paper, we describe, analyze and compare techniques for extracting spatial knowledge from a terrain model. Specifically, we investigate techniques for extracting a morphological representation from a terrain model based on an approximation of a Morse-Smale complex. A Morse-Smale complex defines a decomposition of a topographic surface into regions with vertices at the critical points and...

Irregular applications comprise a significant and increasing portion of jobs running in parallel environments. Recent research has shown that, in parallel environments, both the system utilization and application turn around time improve when resources allocated to applications can be dynamically adjusted at run-time, depending on the workload. To realize this, at least some of the parallel app...
