A Nonoverlapping Domain Decomposition Method for Symm's Equation for Conformal Mapping

Symm’s equation is a first-kind integral equation for computing conformal maps of simply connected regions. The package CONFPACK solves Symm’s equation by an indirect boundary element method using an accurate corner representation. This solution technique is extended here to include nonoverlapping domain decomposition. Degrees of freedom are introduced on one or more interfaces and different un...

A Domain Decomposition Method for Silicon Devices

A mesoscopic/macroscopic model for self-consistent charged transport under high field scaling conditions corresponding to drift-collisions balance was derived by Cercignani, Gamba, and Levermore in [4]. The model was summarized in relationship to semiconductors in [2]. In [3], a conceptual domain decomposition method was implemented, based upon use of the drift-diffusion model in highly-doped r...

Output-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data

The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...

A Domain Decomposition Method: A Simulation Study

A New Method for Color Gamut Mapping by Genetic Algorithm

To reproduce an image, it is necessary to map out of gamut colors of the image to destination gamut. It is clear that the best color gamut mapping introduces the perceptually closest image to the original one. In this study, a new color gamut mapping is purposed by the aid of Genetic Algorithm (GA). The color difference between the original and mapped images based on S-LAB formula was chosen as...
