Publication number: 20110191359Abstract: The present invention establishes a process for creating a set of structures that allows efficient storage and subsequent handling. The multigraph is represented using bitmaps with element counters and mappings between values and organized bitmaps to faciliate the handling of the multigraphs. The bits in the bitmaps represent two aspects of the multigraph: 1) indexing of all the objects of the multigraph as a function of their identifiers and 2) connectivity between objects of the multigraph, whether they are vertices or edges. Mappings allow, given a value, accessing the objects of the multigraph which contain such value. Multigraph operations are solved by accessing the mappings and applying logical operations on the bitmaps. This way of representing a graph allows efficiently performing graph operations such as: inserting a vertex or an edge, inserting an attribute, acquiring the incoming and outgoing edges of an attribute, etc.Type: ApplicationFiled: January 24, 2011Publication date: August 4, 2011Applicant: UNIVERSITAT POLITECNICA DE CATALUNYAInventors: Josep Lluis LARRIBA PEY, Norbert Martínez Bazan, Victor Muntes Mulero, Sergio Gómez Villamor

Publication number: 20080159757Abstract: The present development includes a first element of an optical fibre entrance by which an information carrying signal is transmitted, an optical detector block, a non-linear equalizer block and a final processor block. The development includes an electrical non-linear equalizer block, connecting the output of the optical detector block and the input of the final processor block that compensates the quadratic non-linear characteristic of the optical detector block. Both blocks thus may present a more linear joint characteristic between the electrical field envelope of the information carrying signal in the optical fibre and the electrical signal. Consequently, the final processor block can compensate, in a more effective form, for the linear distortions that the information carrying signal suffers in the transmission through the fibre.Type: ApplicationFiled: February 20, 2006Publication date: July 3, 2008Applicant: UNIVERSITAT POLITECNICA DE CATALUNYAInventors: Josep Prat Goma, Pierluigi Poggiolini
