Elements of general theory of null-balance circuits
1998 Midwest Symposium on Circuits and Systems (Cat. No. 98CB36268), 2002The null-balance method of output indication is widely used in instrumentation techniques and sensor applications. Yet, the theorems and methods of general circuit theory that are the basis of the null-circuit analysis and design have nearly disappeared from the modern books on network theory.

A general transformation with applications to circuit theory
Journal of the Franklin Institute, 1968Abstract A general functional transformation is introduced and some applications to circuit theory are given. The transformation is most useful in the area of active, nonbilateral circuits. This functional transformation introduces new voltages and currents which are linear combinations of the original voltages and currents plus their derivatives ...

A General Theory of Circuit Analogy in Fracture Diagnosis.
1984Abstract : The present report develops electrical analogs to investigate multiple cracks on simple beams and more complex frame structures. Analog networks provide the economic tool to analyze such structures. The effect of multiple cracks on the natural frequencies of simple structures is studied in detail.

General theory of multi-leg power conversion circuits based on neutral point voltage
ISIE'2000. Proceedings of the 2000 IEEE International Symposium on Industrial Electronics (Cat. No.00TH8543), 2002This paper describes the general theory of the main circuit constructions and control methods of legs based on output neutral point voltage control under multi-leg power conversion circuits. A controllable fluctuation range of the output neutral point voltage is obtained by the linear programming method under the condition of the desired symmetrical ...

The general fluid circuit theory of active chloride absorption
The Bulletin of Mathematical Biophysics, 1940The original fluid circuit theory used to explain active intestinal absorption of chloride is modified to include diffusion and secretion of chloride and osmosis. The general differential equation developed is integrated in a particular case. The definition, “effective concentration of chloride in the fluid passing into the intestinal lumen,” leads to ...

A generalized equivalent circuit in the theory of polyphase commutator motors
Electrical Engineering, 1941The demand for speed variation and power-factor compensation in a-c motors led to the development of the polyphase commutator types. In their simplest form these motors consist of two windings; a stator winding which is identical with that of the polyphase induction motor and a rotor winding of the closed type provided with a commutator and similar to ...

Notice of Retraction: Analysis of Loss Compensation on Generation Rights Trade by Circuit Theory
2010 Asia-Pacific Power and Energy Engineering Conference, 2010The generation rights trade could make the losses change, which should be compensated by the trade participants, so the fair loss compensation principle should be established, it could not only help for confirming the traders' responsibilities, but also help the generation rights trade to develop very quickly. This paper thinks that the key of solution

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
This paper presents a general analysis of the 3rd-order nonlinearity of a single-ended and differential common-emitter (CE) radio frequency (RF) amplifier. With direct computation of the third-order nonlinear response, a closed-form expression was derived. The results suggested several novel ways to cancel the third-order nonlinearity without affecting

An improved FDTD formulation for general linear lumped microwave circuits based on matrix theory
IEEE Transactions on Microwave Theory and Techniques, 2005An improved finite-difference time-domain (FDTD) formulation using the matrix theory is presented to analyze hybrid general linear lumped and distribution microwave circuits. Traditionally, since discrete current expressions of lumped circuits should be substituted into Maxwell's equations explicitly, the different discrete formulations of Maxwell's ...

New approach to general theory of electrical machines using magnetic equivalent circuits
Proceedings of the Institution of Electrical Engineers, 1973First, the nature of equivalent circuits and the alternative electric or magnetic equivalents for any electromagnetic system are examined. In the remaining Sections, steady-state and symmetrical sudden short-circuit conditons are analysed for the3-phase synchronous, the 3-phase induction and the compounded d.c.
