The admittance o• a turbulent jet as the generator in organ flue pipes was investigated experimentally with respect o the relevant parameters, that is, the frequency, the jet effiux velocity, the mouth end-correction, and the jet tip deflection at the cdge. First, an experiment was performed using a jet with a pulsating velocity to drive a pipe to isolate and identify the various drive mechanis...

A new method for the synthesis of RC one ports and two-ports is proposed in this paper. A new model of the human body, computed using this method, is developed. This model proves to be more accurate than the classical Cole model. The proposed synthesis method can be used to compute reduced order models (ROM), preserving the circuit passivity, unlike most known ROM computation methods. Key-Words...

The linear response conductance coefficients are calculated in the scattering approach at finite frequency, damping and magnetic field for a microstructure in which the reservoirs are modeled as quantum wire leads of infinite length but finite width. Independently of frequency, inelastic scattering causes sub-bands with large group velocity to contribute more strongly to the conduc-tance than c...

A novel method is proposed to synthesize dual-band bandpass filters (BPFs) from a prototype lowpass filter. By implementing successive frequency transformations and circuit conversions, a new filter topology is obtained which consists of only admittance inverters and series or shunt resonators, and is thereby easy to be realized by using conventional distributed elements. A microstrip dual-band...

The paper proposes a novel method for the optimal parameter selection of the discrete-time switch model used in circuit solvers that adopt the Fixed Admittance Matrix Nodal Method (FAMNM) approach. As known, FAMNM-based circuit solvers allow to reach efficient computation times since they do not need the inversion of the circuit nodal admittance matrix. However, these solvers need to optimally ...

A piezoelectric bimorph beam, as an upgraded cantilever beam structure, can be used to detect gas content and build a micro-actuator, among other functions. Thus, this beam is widely applied to microelectromechanical systems (MEMS), transformers, and precision machinery. For example, when photoacoustic spectroscopy is performed to detect oil-soluble gas in transformers, a micro-cantilever beam ...

This paper proposes a novel method for the optimal parameter selection of the discrete-time switch model used in circuit solvers that adopt the fixed admittance matrix nodal method (FAMNM) approach. As known, FAMNM-based circuit solvers allow to reach efficient computation times, in particular for realtime simulation applications, since they do not need the inversion of the circuit nodal admitt...
