Impedance

Abstract

THE CHAIRMAN [W. J. Hammer]:-The Chair wishes to an-nounee that at the meeting of the Couneil this afternoon the certificate of membership whieh, doubtless, you have all seen in the adjoini'ng room, was adopted with one or two slight changes., This certificate will be issued to full members onily. It will be a comipliment fromn the Institute to those wlio have attained a high rank professionally, and whose work in their profession and for the Institute entitles thein to receiv7e it. These certificates. will probably be ready within two or three weeks and. will be printed upon heavy parchrnrent paper at abont cost, namely, one dollar. The Secretary has beern instrutcted to send out a notice, stating the conditions under which this certificate is givenl and other matters pertainiing thereto, as soon as they are ready for distribution. rThe American Institute of Electrical Engineers desires to raise its status as a scientific organization in every way possible, and it is believed that by issuing this certificate to full members only, the honor conferred will be more highly appreciated and it will result in a desire upon the part of many of our associate inembers to apply for and to secure full membership in the Institute. While in soine of the engineering societies the majority of the members are active or full members, and there are comiparatively few associate metm)bers, in the Institute of Electrical ETngineers the opposite is the easy, and the issuing of this certificate under the cornditions as recommended by the Special Commnittee will prove advantageous to the interests of the Institute as well as to the miembers receiving the saine.

EEG synchrony during a perceptual-cognitive task: Widespread phase synchrony at all frequencies

“…Construction of a resultant phasor for a composite signal consisting of multiple individual signals of the same frequency has been an accepted procedure in ac circuit theory for well over a century (Kennelly, 1893). Essentially, all we are doing is extending that procedure to composite waves consisting of multiple individual signals of different frequencies.…”

Memory Impedance in TiO2 based Metal-Insulator-Metal Devices

“…Such phenomena simply manifest the co-existence of distinct memory modalities 20 , which collectively facilitate a response that inevitably differs from the classical theoretical definition; one should be able to disentangle the individual contributions within single devices. The coexistence of parasitic effects has been observed on practical devices for more than a century 21 22 , with this effect being more apparent when the devices' characteristics are exploited in broad frequency spectrums where the static parasitic contributions are more notable. We argue that practical solid-state devices would experience dynamic parasitic contributions and it is thus more appropriate to investigate the devices' response utterly as memory impedance.…”

Effect of Zirconium Oxide Nanofiller and Dibutyl Phthalate Plasticizer on Ionic Conductivity and Optical Properties of Solid Polymer Electrolyte

“…Figure 1 shows the typical impedance plot of pure PEO, (PEO/LiCF 3 SO 3 ), (PEO/LiCF 3 SO 3 /DBP), and (PEO/LiCF 3 SO 3 /DBP/ZrO 2 ) at room temperature in the frequency range of 50 Hz to 5 MHz. The Cole-Cole plots of the films are consisting of a semicircular arc and inclined spike, both representing behaviour of ionically conducting solid electrolyte films with blocking electrode [ 12 ].…”
