KEY POINTS Regulatory light chain (RLC) phosphorylation has been shown to alter the ability of muscle to produce force and power during shortening and to alter the rate of force redevelopment (ktr ) at submaximal [Ca(2+) ]. Increasing RLC phosphorylation ∼50% from the in vivo level in maximally [Ca(2+) ]-activated cardiac trabecula accelerates ktr . Decreasing RLC phosphorylation to ∼70% of the...

This paper deals with PID compensator control of Synchronous Rectifier (SR) Buck Converter to improve its conversion efficiency under different load conditions with the help of a Zero Voltage Switching(ZVS)Logic Circuit. Since the freewheeling diode is replaced by a high frequency switch MOSFET in this buck configuration, the SR control technique itself will be sufficient under heavy load condi...

An algorithm to compute a reduced-order model of a linear dynamic system is described. It is based on the rational Krylov method, which is an extension of the shift-and-invert Arnoldi method where several shifts (interpolation points) are used to compute an orthonormal basis for a sub-space. It is discussed how to generate a reduced-order model of a linear dynamic system, in such a way that the...

This work investigates the application of bifurcation diagrams in the chaotic study of nonlinear RLC electrical circuits. The relevant second order differential equations were solved for ranges of appropriate parameters using Runge-Kutta approach. The solutions obtained were employed to produce bifurcation diagrams using Microsoft excel 2007. The mean estimate of 669 . 4   obtained from the b...

This paper proposes a new approach to ac circuits numerical simulation. After introducing spiral vector theory which is a new ac theory, I apply this new theory to ac circuits numerical simulation and propose a new approach that uses spiral vector state variables in both steady and transient state situation. Furthermore, with an ac RLC series circuit example, I make comparisons between the gene...

Many physical synthesis tools interdigitate signal and power lines to reduce cross-talk, and thus, improve signal integrity and timing predictability. Such approaches are extremely e ective at reducing cross-talk at circuit speeds where inductive e ects are inconsequential. In this paper, we use a detailed distributed RLC model to show that inductive cross-talk e ects are substantial in long bu...

This paper presents a reduction technique that transforms large passive networks into minimal admittance networks between the terminals. In this model, the moments of each admittance are preserved exactly, up to any desired order. Any RLC network (e.g. lumped models of coupled transmission lines) can be dealt with, including inductive coupling between lines. This technique, in combination with ...

The role of phosphorylation of the myosin regulatory light chains (RLC) is well established in smooth muscle contraction, but in striated (skeletal and cardiac) muscle its role is still controversial. We have studied the effects of RLC phosphorylation in reconstituted myosin and in skinned skeletal muscle fibers where Ca2+ sensitivity and the kinetics of steady-state force development were meas...

MEMS Oscillator design for high frequency application is approached in this project and its gain, noise and power are analyzed. The CMOS Micro Electro Mechanical System resonator structure is modeled using its RLC equivalent circuit where all passive components are extracted by COMSOL Mutiphysics tool. MEMS based oscillator requires to be combined with amplifier circuits to improve the performa...

The fundamental role of a notch filter in communication systems is the attenuation, if not outright rejection, of signals whose frequencies lie within a specified passband. If the passband identified for rejection lies at very high frequencies, passive notch filters prove more effective than their active counterparts, but their design realization is necessarily less systematic. In this paper, o...
