Reduced-Order Model for an Impacting Beam using the Karhunen-Loµeve Expansion

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Model Reduction via the Karhunen-Loeve Expansion: An Exposition

Reduced Basis Methods for Parameterized Partial Differential Equations with Stochastic Influences Using the Karhunen-Loève Expansion

We consider parametric partial differential equations (PPDEs) with stochastic influences e.g. in terms of random coefficients. Using standard discretizations such as finite elements, this often amounts to high-dimensional problems. In a multi-query context, the PPDE has to be solved for various instances of the deterministic parameter as well as the stochastic influences. To decrease computatio...

Reduced order model for doubly output induction generator in wind park using integral manifold theory

A dynamic reduced order model using integral manifold theory has been derived, which can be used to simulate the DOIG wind turbine using a double-winding representation of the generator rotor. The model is suitable for use in transient stability programs that can be used to investigate large power systems. The behavior of a wind farm and the network under various system disturbances was stu...

Karhunen-Loève Expansion for the 3D Description

The Karhunen-Loève expansion is used for a compact 3D description of the human body shape. In this paper we show that a compact 3D description can be achieved using a small set of eigenvectors. Experimental results using a database of three-dimensional body scans are presented. Applications are also discussed. 1.Introduction The measurement of the human body (Anthropometry) is an essential part...
