We report on a survey for narrow (FWHM < 600 km s) C iv absorption lines in a sample of bright quasars at redshifts 1.8 6 z < 2.25 in the Sloan Digital Sky Survey. Our main goal is to understand the relationship of narrow C iv absorbers to quasar outflows and, more generally, to quasar environments. We determine velocity zeropoints using the broad Mg ii emission line, and then measure the absor...
قاب های مخلوط تنگ یک مفهوم نوظهور ازنظریه ی قاب هاهستند.این قاب هادر فرآیندپخش و مخابرات کاربردهای زیادی دارند.بااینحالدرموردوجود این قابهااطلاعات کمی وجوددارد.در این پایان نامه به طور کامل مسله ی وجود چنین قاب هایی رادر حالت خاصی که در آن فضای اصلی با بعد متناهی است و زیر فضاهایقاب مخلوط بعد مساوی دارند را به طور کامل حل می کنیم.بدین معنا که شرایطی که تحت آن یک مجموعه از ماتریس های تصویر متعام...
The goal of the present paper is a short introduction to a general module frame theory in C*-algebras and Hilbert C*modules. The reported investigations rely on the idea of geometric dilation to standard Hilbert C*-modules over unital C*-algebras that possess orthonormal Hilbert bases, and of reconstruction of the frames by projections and other bounded module operators with suitable ranges. We...
Review on C12orf5, with data on DNA/RNA, on the protein encoded and where the gene is implicated.
Nomenclature SF a , SFx a , SF y a , SFz a = specific force acceleration vector (sensed by accelerometers) and components in frame B B = sensor (body) coordinate frame aligned with strapdown inertial sensor axes 1 m B = frame B orientation at computer cycle 1 m () Bt = frame B orientation at time t k r c = combination, k elements selected from a set of r elements without regard to the order...
Let H be a Hilbert space. Given a bounded positive definite operator S on H, and a bounded sequence c = {ck}k∈N of non negative real numbers, the pair (S, c) is frame admissible, if there exists a frame {fk}k∈N on H with frame operator S, such that ‖fk‖ 2 = ck, k ∈ N. We relate the existence of such frames with the Schur-Horn theorem of majorization, and give a reformulation of the extended ver...
This paper studies the problem of sequence-to-sequence alignment, namely establishing correspondences in time and in space between two di erent video sequences of the same dynamic scene. The sequences are recorded by uncalibrated video cameras, which are either stationary or jointly moving, with xed (but unknown) internal parameters and relative inter-camera external parameters. Temporal variat...
motivating the perturbations of frames in hilbert and banach spaces, in this paper we introduce the invariance of fr'echet frames under perturbation. also we show that for any fr'echet spaces, there is a fr'echet frame and any element in these spaces has a series expansion.
In this paper, by using the sequence of multipliers, we introduce frames with algebraic bounds in Hilbert pro-$ C^* $-modules. We investigate the relations between frames and $ ast $-frames. Some properties of $ ast $-frames in Hilbert pro-$ C^* $-modules are studied. Also, we show that there exist two differences between $ ast $-frames in Hilbert pro-$ C^* $-modules and Hilbert $ ...
