Cellular base stations (BTS) and microwave relays have detached LNA stages located up in the aerial tower in order to mitigate NF degradation from pre-LNA cable loss. In the BTS architecture, the LNA stage is preceded by a transmit-receive (Tx-Rx) diplexer for duplexing a common aerial and by an interference fi lter for preventing out-ofband blocking or desensitization. However, both duplexer a...

Los árboles de comportamiento son la tecnoloǵıa más utilizada en videojuegos comerciales para programar el comportamiento de los personajes no controlados por el jugador, aunando una gran expresividad, con cierta facilidad de uso que permite la colaboración entre programadores y diseñadores de videojuegos. En este art́ıculo describimos un nuevo tipo de nodos en los BTs que representan consultas ...

Abstract We present a new generalized algorithm which allows the construction of Bäcklund transformations (BTs) for higher order ordinary differential equations (ODEs). This algorithm is based on the idea of seeking transformations that preserve the Painlevé property, and is applied here to ODEs of various orders in order to recover, amongst others, their autoBTs. Of the ODEs considered here, o...
