The performance of asphalt binders at high and low temperatures has an important role on the rutting and crackingresistance of asphalt pavements. Crumb Rubber Modified (CRM) is one of the asphalt modifiers that improves asphaltphysical and mechanical properties and helps reducing environmental pollution. In this research, three unmodifiedand six CRM modified binders were teste...

A simple LRC circuit model is used to conduct a parametric study of the effects of charging voltage, capacitance, resistance, and inductance on the current waveform of a pulse forming network for field reversed configuration (FRC) plasma production. Using known waveforms from existing networks, estimates of realistic values of resistance and inductance are established for a base network model. ...

We describe here a technique called phase tracking that greatly improves the accuracy of measurements of the membrane capacitance of single cells. We have modified the original phase detection technique to include a method for creating calibrated changes in the resistance in series with the cell. This provides a method to automate the adjustment of the phase detector to the appropriate phase an...

Alternating current measurements in biology are concerned with the resistance and capacitance of the cell membrane, and the resistance of the cell interior. No systematic electrical measurements have so far been made on the cell nucleus. Such expressions as resistance, capacitance and impedance are generally associated with wireless sets or wireless components. They have, however, a physico-che...

The model to be described is a “closed” system, comprised of four principal components : a pump, an arterial capacitance, a peripheral resistance, and a venous capacitance. The pump is servo-controlled, such that “cardiac output” is a function of venous pressure (FrankStarling mechanism). Also, because the model is a closed system, the venous pressure is a function of the cardiac output. The mo...

Bode plots, corrected for Ohmic resistance, logarithmic plots of the imaginary component of the impedance, and effective capacitance plots are shown to be useful complements to the more traditionally used complex-plane and Bode representations for electrochemical impedance data. The graphical methods are illustrated by synthetic data and by experimental data associated with corrosion in saline ...

The passive electrical properties of subendocardial Purkinje fibers surviving in infarcted regions of canine ventricle 24 hours after coronary ligation were studied by using microelectrode techniques and cable theory. In normal hearts, cells within the subendocardial Purkinje fiber strands were found to be well coupled to each other but electrically isolated from neighboring myocardium. Voltage...

Along with the rapid development of Internet, CRM has become one of the most important facts leading the enterprises to be competent. At the same time, the analytical CRM based on Date Warehouse is the kernel of CRM system. This paper mainly explains the idea of CRM and the DW model of analytical CRM system.

In this paper the transfer function of a system with windowed current integration is discussed. This kind of integration is usually used in a sampling mixer and the current is generated by a transconductance amplifier (TA). The parasitic capacitance (Cp) and the output resistance of the TA (Ro,TA) before the sampling mixer heavily affect the performance. Calculations based on a model including ...
