In this paper we study the transient behaviour of RC circuits with supercapacitors, varying R between 1 and 100 . We demonstrate that supercapacitors behave as ideal capacitors in series with an internal resistance (r ∼ 8 for C = 0.2 F, 5.5 V). This result is important to optimize the demonstration of RC circuits using a supercapacitor in series with a light bulb, because the r value is compara...

The objective of this paper is to study the effect of the internal transducer resistance on the dynamic behaviour and the output power of an energy harvester when it is attached to a cubic load resistance. It is seen that by considering the internal resistance, the dynamic equation of a conventional nonlinear energy harvester changes so that it is not easy to separate the linear damping from th...

Theoretical and experimental investigation of wear during coupling in internal gears coated with various polymeric coating materials was performed in this study. In the theoretical part of the study, Archards’ wear formulation was adapted to internal gears and wear behavior in various conditions was determined. Moreover, a fatigue and wear testing apparatus having similar working principle with...

Purpose The work of internal auditors is relevant to their host entities' reporting processes; however, few researchers have examined how auditors’ competency and objectivity affect resistance pressure from entities regarding reports. Thus, the main objective this study examine influence audit functions' (IAF) quality factors on chief executives' (CAEs) ability not modify report. Design/methodo...
