Electromagnetic random source for circular optical frame and its statistical properties

tight frame approximation for multi-frames and super-frames

در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...

Frame properties of low autocorrelation random sequences

Research Article Somantika Datta Frame properties of low autocorrelation random sequences Abstract: The goal is to construct random frames and study properties of such frames. Starting with the construction of unimodular random sequences whose expected autocorrelations can be made arbitrarily low outside the origin, these random sequences are used to construct frames for Cd. Using recent theory...

A Statistical Study of Rest - frame Optical Emission Properties in Luminous

We have obtained H-band spectra of 32 luminous quasars at 2.0 ≤ z ≤ 2.5 with the Multiple Mirror Telescope. The sample contains 15 radio-loud quasars (RLQs) and 17 radio-quiet quasars (RQQs). We have measured emission line properties from the rest-frame wavelength range of approximately λλ4500 − 5500, by fitting the data with composite model spectra. Our analysis includes comparison of RLQs ver...

Properties of Bismuth Gernanate and Its Use for Electromagnetic Calorimetry*

The calorimetric and fluorescence properties of Bismuth Germanate are discussed and compared to those of NaI(TI1). Results on the energy resolution of BGO are presented for energies up to 50 MeV; the energy and position resolution are studied by Montecarlos at higher energies. The performance of a 4x BGO e.m. calorimeter is compared to that of NaI and is specified for a compact fieldless calori...
