Two experiments examine speed-up in argument pairs of various propositional forms. In the first experiment, participants were presented with pairs of conditional arguments. Some of these pairs had a form of a valid Modus Ponens (MP) inference, whereas other pairs had a form of a fallacy of Affirming the Consequent (AC). In both argument pairs, presentation of the prime led to a significant spee...
Today’s power systems are large networks of electrical energy sources and load components, connected over long distances mainly through alternating current (AC) transmission and distribution grids. This basic structure currently undergoes significant changes to ensure the stability, availability and sustainability of the future electrical energy infrastructure. As a result, power system operati...
Matrix converter is a single-stage converter which directly connects a three-phase voltage source to a three-phase load without dc-link components. Therefore, any harmonic distortion and imbalance in input voltage directly reflect to the output of the converter. Recently, many researchers have made an effort to cope with this problem. In this paper, under distorted input voltage conditions, beh...
The VCM (Vessel Communication Manager) proposed in this paper consists of ARP (Azimuth based Routing Protocol) and NATF (Network Attack Traceback Facility). The ARP can transmit accident information from a source to a headquarter rapidly and accurately by using Azimuths. It designs the Ac-RREQ message that appends an azimuth, a cumulation S/N, and a standby packet count field to the exiting RRE...
Transmission congestions limit market activities and decrease possible benefits of energy market players. This paper introduces a portfolio of measures for a better use or increase of the transmission capacity of AC transmission lines. Novel approaches like stability monitoring, coordinated control and wide area protection are discussed. Their application to increase available transmission capa...
A detailed study of the valence state and distribution of the AuCl3/AC catalyst during the acetylene hydrochlorination deactivation process is described and discussed. Temperature-programmed reduction and X-ray photoelectron spectral analysis indicate that the active Au(3+) reduction to metallic Au(0) is one reason for the deactivation of AuCl3/AC catalyst. Transmission electron microscopy char...

استفاده از خازن های سری، روش بسیار مناسبی جهت افزایش توان انتقالی در خطوط طولانی می باشد. این احتمال بروز مسائل مربوط به تشدید زیرسنکرون را بالا می برد. این خطر پذیری سبب شده است که طراحان و بهره برداران شبکه های قدرت با توجه به قابلیت ادوات facts به سمت افزون میراکننده های تکمیلی گام بردارند. در مطالعه پایداری سیستم های قدرت بزرگ، بحث میراسازی تشدید زیرسنکرون دارای اهمیت به سزایی است. در این م...
We compare approaches to measure oxygen surface exchange kinetics, by simultaneous optical transmission relaxation (OTR) and AC-impedance spectroscopy (AC-IS), on the same mixed conducting SrTi0.65Fe0.35O3-x film. Surface exchange coefficients were evaluated as a function of oxygen activity in the film, controlled by gas partial pressure and/or DC bias applied across the ionically conducting yt...
