The quality of the current waveform generated by a current-controlled, voltage source inverter, depends basically on three factors: (a) the switching frequency of the PWM modulator; (b) the type of current waveform being ...

The class of piezoelectric actuators considered in this paper consists of a multi-flexible structure actuated by two or more piezoceramic devices that must generate different output displacements and forces at different ...

This paper presents the design and implementation details of a complete noncontact (NC) voltage acquisition system, which allows the measurement of power-line voltage waveforms without galvanic contact. The system is ...

Ti-6Al-4V alloy turbine components for aeronautical applications operate at a steady state after reaching the maximum stress during each duty cycle. The load holds combined with the fatigue process causes a phenomenon ...

The waveform generator is one of the most important measurements equipment. It provide controllable electrical signals that are used in circuit testing. This device is capable of generating periodic or non-continuous ...

The afferent input of thermal stimuli and pain to the central nervous system is carried by myelinated (Aä) and non-myelinated (C) fine fibers, which have been studied up to this point. An important contribution to this ...
