از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...
متن کاملIn vitro Comparison of Conventional Film and Direct Digital Radiography in Proximal Caries Detection
Introduction: Various systems for intraoral digital radiography have been available as an alternative to film–based radiography. In consideration of several advantages of digital radiography such as less patient absorbed dose, manipulation of image quality and elimination of processing, it has been extensively used in different fields of dentistry in recent years. The purpose of this study wa...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
An experimental comparison of detector performance for direct and indirect digital radiography systems.
Current flat-panel detectors either directly convert x-ray energy to electronic charge or use indirect conversion with an intermediate optical process. The purpose of this work was to compare direct and indirect detectors in terms of their modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE). Measurements were made on three flat-panel detectors,...
