In this note we resolve the problem of getting a state-space realization compatible with the deterministic state-space realization and the filtering problem.

In this report a lumped transfer function model for High Pressure Natural Gas Pipelines is derived. Starting with a partial nonlinear differential equation (PDE) model a high order continuous state space (SS) linear model is obtained using a finite d

In this work, we present an interferometric polymer-based electro-optical device, integrated with an embedded double-monolayer graphene capacitor for biosensing applications. An external voltage across the capacitor applies an electric field to the g

In this work, an interferometric polymer-based electro-optical biosensor with an embedded double monolayer graphene capacitor is presented. Because of the Fermi level modulation, absorption changes of 129dB/mm and bulk sensitivity of 2828nm/RIU respe

We propose and use a technique to measure the transverse emittance of a laser-wakefield accelerated beam of relativistic electrons. The technique is based on the simultaneous measurements of the electron beam divergence given by v_{⊥}/v_{∥}, the

Identification of a Benchmark Wiener–Hammerstein: A bilinear and Hammerstein–Bilinear model approach
Publikováno v:
Control Engineering Practice. 20:1156-1164
In this paper the Wiener–Hammerstein Benchmark is identified as a bilinear discrete system. The bilinear approximation relies on both facts that the Wiener–Hammerstein system can be described by a Volterra series which can be approximated by bili

We address the identification of discrete-time linear parameter varying systems in the state-space form with affine parameter dependence. In previous work, some of the authors have addressed this problem and an iterative algorithm that avoids the cur

In this paper a new approach to gas leakage detection in high pressure natural gas transportation networks is proposed. The pipeline is modelled as a Linear Parameter Varying (LPV) System driven by the source node massflow with the gas inventory vari

The salicylic acid oxidation has been explained by a mechanism involving single electron transfer oxidation and single hydrogen transfer using quantum chemistry calculations at the B3LYP theory level, together with the 6-311G** basis set. These metho
