The Optimum Design of a Step Voltage Regulator.
Optimum designs of voltage regulating transformers can be achieved only when the designer knows the characteristics of the different design parameters and how they affect the total design. The criteria controlling the design of most voltage regulating transformers are not readily available since …

Monte Carlo simulation of ion transport of high strain ionomeric polymer transducers
… cations can hop around in a square lattice. A step voltage is applied between the electrodes of the IPT, causing the thermally-activated hopping between multiwell energy structures. By sampling the ion transition time interval as a random variable, the system evolution is obtained. Conducting …

Development of a pulsed eddy current instrument and its application to detect deeply buried corrosion
… which requires the coil to be excited by a step function and the response of the coil monitored. Since the coil is excited with a spectrum of frequencies contained in the step function, similar information content to the swept frequency method is available. In this thesis, the electronic …

Feedback Control of Ionic Polymer Actuators
… large deformation in the presence of low applied voltage across its thickness and exhibits low impedance. They can also be used as large displacement sensors by bending them to induce stresses and generate a voltage response. They operate best in a humid environment. Ionic polymer actuators have …
