Antoranz Canales, Pedro ; Vegas Azcárate, Ignacio ; Miranda Pantoja, José Miguel | Elsevier Science BV | 2010-08-11We present in this paper the design, fabrication and verification of a us-range pulse generator based on a Step Recovery Diode (SRD). This device needs only a 5 V DC power supply, delivers 1 ns pulses with peak amplitudes in excess of 4 V and fe[...]![]()

Rodriguez, A. ; Martín-Delgado Alcántara, Miguel Ángel ; Rodriguez-Laguna, J. ; Sierra, G. ; Malyshev, Andrey ; Domínguez-Adame Acosta, Francisco ; Lemaistre, I. J. | Elsevier Science BV | 2001-12The standard one-parameter scaling theory predicts that all eigenstates in two-dimensional random lattices are weakly localized. We show that this claim fails in two-dimensional dipolar Frenkel exciton systems. The linear energy dispersion at th[...]![]()

In this paper we study the adjacency structure of the order polytope of a poset. For a given poset, we determine whether two vertices in the corresponding order polytope are adjacent. This is done through filters in the original poset. We also p[...]![]()

Quiroga Mellado, Juan Antonio ; Gómez Pedrero, José Antonio ; García Botella, Ángel | Elsevier Science BV | 2001-09-15In this work we present a new algorithm for fringe pattern normalization, that is. background suppression and modulation normalization. Normalization is necessary for several fringe pattern processing techniques. For example, this is the case of[...]![]()
