Reciprocity of linear systems with smart materials utilized for precise measurement techniques

In electromechanical measurement techniques, passive transducers and passive electrical networks often interact. In some applications, continua are considered as part of the system, where fields are formed and waves are propagated. In this article, networks, continua, and electromechanical transducers feature sufficient amplitude linear behavior in their environment (e.g. for operation around a bias) and are reciprocal. In addition, all elements of the system have constant parameters during the measurement. Then, the skillful application of the inherent reciprocity of these systems can lead to surprisingly useful benefits. This is shown by actual examples from metrology. The examples include the precise determination of transduction coefficients. It is also shown how the linearity of a system is checked by utilizing reciprocityrelations. Although the facts of the matter are well known, its potential is often overlooked or disregarded in measurement techniques

Si en «Tramas IV» y «Tramas V» mostraba que al lado de la trama principal caballeresco-berberisca dirigida por don Quijote (cf. «Tramas III») Cervantes sugiere un segundo programa narrativo en el cual son los duques los que toman las riendas de la aventura con el fin de que los dos héroes sean asimilados a unos brujos que conviene frenar y castigar, en este nuevo artículo, se insiste en la contraofensiva cervantina que, en filigrana, revela que en realidad son aquellos, los aristócratas aragoneses, los que se comportan como seres diabólicosIf in «Tramas IV» and «Tramas IV» I showed that at side of the main thread –chivalrous– directed by Don Quixote (see «Tramas III») Cervantes suggests a second narrative program in which the dukes take the reins of the adventure in order to assimilate the two heroes to witches that should be curbed and punished, in this new article, I insist on the cervantine counter-offensive which obliquely reveals that in reality they are this Aragonese aristocrats, who behave as diabolical being
