Tunable pulse delay and advancement device based on a cavity electromechanical system

task-based language teaching in iran: a mixed study through constructing and validating a new questionnaire based on theoretical, sociocultural, and educational frameworks

جنبه های گوناگونی از زندگی در ایران را از جمله سبک زندگی، علم و امکانات فنی و تکنولوژیکی می توان کم یا بیش وارداتی در نظر گرفت. زبان انگلیسی و روش تدریس آن نیز از این قاعده مثتسنی نیست. با این حال گاهی سوال پیش می آید که آیا یک روش خاص با زیر ساخت های نظری، فرهنگی اجتماعی و آموزشی جامعه ایرانی سازگاری دارد یا خیر. این تحقیق بر اساس روش های ترکیبی انجام شده است.پرسش نامه ای نیز برای زبان آموزان ...

Distortion free pulse delay system using a pair of tunable white light cavities.

Recently, a tunable bandwidth white light cavity (WLC) was demonstrated by using an anomalously dispersive intra-cavity medium to adjust a cavity linewidth without reducing the cavity buildup factor [G.S. Pati et al., Phys. Rev. Lett. 99, 133601 (2007)]. In this paper, we show theoretically how such a WLC can be used to realize a distortion-free delay system for a data pulse. The system consist...

Infraspinatus Electromechanical Delay on Shoulder Instabilities

Shoulder instability is a major complaint in overhead athletes. The shoulder joint stability is provided mainly by rotator cuff muscles. The Electromechanical Delay (EMD) may be an important parameter in the responsiveness of a muscle. The aim of this study was to measure and compare the infraspinatus EMD in healthy and unstable shoulders and in dominant and non-dominant shoulders. We did not f...
