Using state-space techniques to represent frequency dependent single-phase lines directly in time domain
This paper proposes to use a state-space technique to represent a frequency dependent line for simulating electromagnetic transients directly in time domain. The distributed nature of the line is represented by a multiple ...
The increase of the states number and their internal fragilities
(Univ Barcelona, Dept Geografia HumanaBarcelonaEspanha, 2008)
A reduced order state space model for aeroelastic analysis in time domain
The objective of this paper is to describe a new method for modeling aeroelastic system in time domain based on a modification of the Laguerre Polynomials to represent complex quantities. These polynomials are used to ...
Determination of density of states in PPS from space-charge-limited current measurements
Space-charge-limited currents measurements have been carried out on undoped amorphous poly p-phenylene sulfide. The scaling law is checked for different samples with varying thickness, and J-V data analyzed. The position ...
Tri-state Space Vector Modulation for Three-phase integrated inverters
The aim of this work is to present a modified Space Vector Modulation (SVM) suitable for Tri-state Three-phase inverters. A standard SVM algorithm and the Tri-state PWM (Pulse Width Modulation) are presented and their ...
The IDEOLOGY SPACE BRAZILIAN NATIONAL STATE OF CONSTITUTIVE
(UNIV BARCELONA, DEPT GEOGRAFIA HUMANABARCELONA, 2012)
In the debate over the construction of the Brazilian national state, we assume that this process has established itself at the heart of a fragmentary appreciation of their aesthetic variants, forming a controversial ideology ...
Bethe-Salpeter bound-state structure in Minkowski space
(Elsevier B.V., 2016-08-10)
The quantitative investigation of the scalar Bethe-Salpeter equation in Minkowski space, within the ladder-approximation framework, is extended to include the excited states. This study has been carried out for an interacting ...
Conceptual spaces and consciousness: Integrating cognitive and affective processes
In the book Conceptual Spaces: the Geometry of Thought  Peter Gärdenfors proposes a new framework for cognitive science. Complementary to symbolic and subsymbolic [connectionist] descriptions, conceptual spaces are ...
