Using ideas from Chu and Bode/Fano theories, we characterize the maximum achievable rate over single-input single-output wireless communication channels under a restriction on antenna size at receiver. By employing circuit-theoretic multiport models for radio systems, derive information-theoretic limits of compact antennas. We first describe an equivalent Chu’s circuit physical realizability co...

This paper presents a novel multi-port DC/DC converter which is suitable to be used as the interface of hybrid renewable energy systems. The converter contains three unidirectional power flow ports which two of them are input ports and are connected to two independent energy sources while the third one is the output port that feeds a standalone load. Furthermore, the proposed converter contains...

We introduce control engineering as a new domain of application for formal methods. We discuss design verification, drawing attention to the role played by diagrammatic evaluation criteria involving numeric plots of a design, such as Nichols and Bode plots. We show that symbolic computation and computational logic can be used to discharge these criteria and provide symbolic, automated, and very...

written for a particular gain. Then KGH = −1 so that a) when the amplitude of KGH is 1 or 0 dB and b) phase is 180o then we have the system just become unstable. Both the conditions have to be fulfilled. Hence, if we ask the question: How far is the system from instability ? We get two answers. The gain increment required at the frequency where phase is 180o and the phase increment required at ...

In an observational study, COTE and CELLI [1] showed that the response to outpatient PR can be objectively measured using the BI, whose change provides information regarding ultimate survival, and that participation in a PR is associated with a decrease in the number of hospitalisations. This multidimensional 10-point scale has been previously shown to predict the death risk in COPD patients [2].
