Theoretical evaluation of asynchronous ac dielectric nanomotors

Probe-Fed Rectangular Dielectric Resonator Antennas,Theoretical Modeling and Experiments

A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE 111. Antenna parameters under investigation inclu...

Nondestructive Evaluation of Buried Dielectric Cylinders by Asynchronous Particle Swarm Optimization

Ac 2009-1571: the Effectiveness of Asynchronous Podcasting of Classes

In this study we examine in some detail the effectiveness of enhanced podcasting compared with traditional face-to-face class meeting. Enhanced podcasting goes beyond simply recording the audio portion of a lecture. It may include the video footage from the class meeting or, as in our case, the presented material (including each written pen stroke) exactly as seen by students sitting in the cla...

Dielectric nonlinearity of relaxor ferroelectric ceramics at low ac drives

Dielectric nonlinear response of (PbMg1/3Nb2/3O3)0.9(PbTiO3)0.1 (0.9PMN0.1PT) relaxor ceramics was investigated under different ac drive voltages. It was observed that: (i) the dielectric permittivity is independent on ac field amplitude at high temperatures; (ii) with increasing ac drive, the permittivity maximum increases, and the temperature of the maximum shifts to lower temperature; (iii) ...
