Analysis of Various Methodologies for Generation of Microwave Chaos Spectrum and improved microwave colpitts oscillator

This paper describes various methods of generation of microwave chaos signal spectrum origin from certain continuous dynamical systems – that may exhibit dynamics of signals that are highly sensitive to initial conditions. Many side lobes in chaos signal spectrum which makes the unambiguous detection difficult because of the spectrum of the chaotic signal is not very fat and smooth, with pulsat...

Dual microwave and optical oscillator.

We describe and demonstrate a novel device in which a microwave oscillation and an optical oscillation are generated and directly coupled with each other. With the mutual influence between the microwave and the optical oscillations, we project that this device is capable of simultaneously generating stable optical pulses down to the subpicosecond level and spectrally pure microwave signals at f...

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
