A straightforward method for tuning of Lyapunov-based controllers in semi-active vibration control applications
(Elsevier, 2013-11-15)
Lyapunov-based control is an attractive strategy for semi-active vibration control as it has a mathematical basis ensuring stability in the sense of Lyapunov and great flexibility in the design. Unfortunately, that flexibility ...
A framework to integrate history matching and geostatistical modeling using genetic algorithm and direct search methods
(Elsevier Science BvAmsterdamHolanda, 2008)
Stability analysis of power system including facts (TCSC) effects by direct method approach
(2005-05-01)
The problem of power system stability including the effects of a flexible alternating current transmission system (FACTS) is approached. First, the controlled series compensation is considered in the machine against infinite ...
A method to deconvolve stellar rotational velocities II: The probability distribution function via Tikhonov regularization
(EDP Sciences, 2016-11)
Aims. Knowing the distribution of stellar rotational velocities is essential for understanding stellar evolution. Because we measure the projected rotational speed v sin i, we need to solve an ill-posed problem given by a ...
On non-ideal and non-linear portal frame dynamics analysis using Bogoliubov averaging method
(2002-11-01)
We apply the Bogoliubov Averaging Method to the study of the vibrations of an elastic foundation, forced by a Non-ideal energy source. The considered model consists of a portal plane frame with quadratic nonlinearities, ...
Direct-location vs. verbal report methods for measuring auditory distance perception in the far field
(Springer, 2017-06)
In this study we evaluated whether a method of direct location is an appropriate response method for measuring auditory distance perception of far-field sound sources. We designed an experimental set-up that allows ...
First-order doubly-asymptotic formulation of the direct stiffness method for elastodynamic problems
(Elsevier, 2014-11)
A first-order formulation to analyze the dynamic response of layered soil profiles is presented as an alternative to the widely used second-order thin-layer method by the direct stiffness approach, including an efficient ...
Spray-Dried Cascara sagrada Extract for Direct Compression: Tablet Formulation and a Simple HPLC Method for Tablet Performance Evaluation
(International journal of research in pharmaceutical and biomedical sciences, 2013-12)
Cascara sagrada bark is extensively used in the treatment of occasional constipation. Despite its wide diffusion, Cascara sagrada dried extracts with good flow and compactability properties for tablet formulation by direct ...
Approximate dynamic programming via direct search in the space of value function approximations
(Elsevier Science BvAmsterdamHolanda, 2011)
A Study on Unconditionally Stable FDTD Methods for the Modeling of Metamaterials
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
We assess the performance of three unconditionally stable finite-difference time-domain (FDTD) methods for the modeling of doubly dispersive metamaterials: 1) locally one-dimensional FDTD; 2) locally one-dimensional FDTD ...
