Bistatic forward-looking SAR (BFSAR) has many potential applications, such as selflanding in bad weather and military detection. Therefore, BFSAR receives considerable attention recently. The imaging algorithms for BFSAR are the difficulties of the study. The original Loffeld’s Bistatic Formula (LBF) can handle most general bistatic SAR configurations well. But in some complex bistatic geometri...

Se analiza el grado de aplicación del estándar RDA (Resource Description and Access) en las Bibliotecas Públicas Estado españolas. Para ello, se procede a la elaboración una encuesta tomando como escenario tres posibles casuísticas: que estas bibliotecas ya hayan implementado código anglosajón; desechado opción aplicarlo; o aún no tomado decisión al respecto. De 53 remitió cuestionario, ha reca...

We evaluated the predictions of Grosz and Sidner’s theory of anaphoric accessibility using a corpus of tutorial dialogues whose discourse structure was annotated according to Relational Discourse (RDA) Analysis. We found support for Moser and Moore’s proposal that only segments with an intentional core should be viewed as introducing new focus spaces; we also found that both embedded cores and ...

the range imaging based on conventional pulse compression technique requires lfm signal that sampled by nyquist rate. in order to high resolution increased in range in pulse compression, so the lfm bandwidth has to increase. consequently this procedure dictated limitations on adc sampling. the stretch processing is one of techniques decreasing nyquist rate in radars. in this method the nature o...

Resource-driven automata (RDA) are finite automata, sitting in the nodes of a finite system net and asynchronously consuming/producing shared resources through input/output system ports (arcs of the system net). RDAs themselves may be resources for each other, thus allowing the highly flexible structure of the model. RDA-nets are expressively equivalent to Petri nets [2]. In this paper a new fo...

Design/methodology/approach The article analyzes different methods previously developed for authority control as well as IFLA and ALA standards for managing bibliographic records. Semantic Web technologies are also evaluated. AUTHORIS relies on Drupal and incorporates the protocols of Dublin Core, SIOC, SKOS and FOAF. The tool has also taken into account the obsolescence of MARC and its substit...
