The single flux quantum (SFQ) logic family is a novel digital as it provides ultrafast and energy-efficient circuits. For large-scale SFQ circuit design, specialized electronic design automation (EDA) tools are required due to the differences in type, timing constraints, architecture, contrast Complementary metal–oxide–semiconductor (CMOS) logic. In order improve overall performance of an circu...

Dual scattering channel (DSC) schemes generalize Johns’ TLM algorithm in replacing transmission lines with abstract scattering channels in terms of paired distributions. A well known merit of TLM schemes is unconditional stability, a property generally drawn upon passivity of linear transmission line networks. So the question arises, if DSC algorithms remain stable in a neat sense. It is shown ...

We use an averaging method to study the dynamics of a transmission line studded by Josephson junctions. The averaged system is used as a springboard for studying experimental strategies which rely on spatial non-uniformity to achieve enhanced synchronization. A reduced model for the near resonant case elucidates in physical terms the key to achieving stable synchronized dynamics. © 2004 Elsevie...

Due to limitations of 0.618 pole method, the triangle method and the champ ground resistance tester method on grounding resistance measurement of transmission lines and towers under conditions of complex landscape in a mountainous area, it adopts a generalized three-electrode grounding resistance measurement method which arranges electrode flexibly in the grounding resistance measurement of tra...

The transmission line pulse method (TLP) is used to characterise the reliability of bolometric GaAs microwave power-sensors. Two degradation mechanisms are identified during the degradation process of the absorbing NiCr termination, in which the input power is converted into heat. Simulations and a material analysis have been performed in order to characterise the observed degradation mechanisms.

In this paper tools for the analysis of Dirac structures on Hilbert spaces are developed. Some properties are pointed out and two natural representations of Dirac structures on Hilbert spaces are presented. The theory is illustrated on the example of the ideal transmission line. keywords: Power conserving structures, Dirac structures, Representations. AMS-Classification: 93C25, 93A30, 93B10, 70...

This paper presents the overview of studies on the abnormal oscillations which have been occurred in the power transmission systems in Japan. It also focuses on the recent studies of the dynamics of the subharmonic oscillation of order 113 in a nonlinear three-phase circuit which is the fundamental model of the series-compensated transmission line.

Network modeling of complex physical systems leads to a class of nonlinear systems called port-Hamiltonian systems, which are defined with respect to a Dirac structure (a geometric structure which formalizes the power-conserving interconnection structure of the system). A power conserving interconnection of Dirac structures is again a Dirac structure. In this paper we study interconnection prop...

Considering generator rotor and valve by external disturbances for turbine regulating system, the nonlinear large disturbance attenuation controller and parameter updating law of turbine speed governor system are designed using backstepping method. The controller not only considers transmission line parameter uncertainty, and has attenuated the influences of large external disturbances on syste...

A modified two-element Yagi-Uda antenna with tunable beams in the H-plane (including four significant beams: forward, backward, omni-directional, and bi-directional beams) is presented. These tunable beams are achieved by simply adjusting the short-circuit position of the transmission line connected to the parasitic element. The principle of operation is investigated by examining the current re...
