Finite normalized tight frames are interesting because they provide decompositions in applications and some physical interpretations. In this article, we give a recursive method for constructing them.

‎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 $ ...

we give some new results on sparse signal recovery in the presence of noise, forweighted spaces. traditionally, were used dictionaries that have the norm equal to 1, but, forrandom dictionaries this condition is rarely satis ed. moreover, we give better estimationsthen the ones given recently by cai, wang and xu.

In this paper we study the duality of Bessel and g-Bessel sequences in Hilbert spaces. We show that a Bessel sequence is an inner summand of a frame and the sum of any Bessel sequence with Bessel bound less than one with a Parseval frame is a frame. Next we develop this results to the g-frame situation.

We propose a real-time fingertip detection algorithm based on depth information. It can robustly detect single fingertip regardless of the position and direction of the hand. With the depth information of front view, depth map of top view and side view is generated. Due to the difference between finger thickness and fist thickness, we use thickness histogram to segment the finger from the fist....

This paper introduces a set of analytical frames that explore the possibilities of conceiving, researching and writing a global geography of squatting. The paper argues that it is possible to detect, in the most tenuous of urban settings, ways of thinking about and living urban life that have the potential to reanimate the city as a key site of geographical inquiry. The paper develops a modest ...

Designed as action research, this qualitative study aims to develop the informational text writing skills of gifted students through strategies “all about” books and frames for biographies. The group research consists 21 4th grade studying in field general mental ability a Science Art Center spring semester 2020-2021 academic year. An eight-week plan was prepared support development these stude...

We report one of the first comparative studies on two mature approaches to generative programming: XVCL and GenVoca. XVCL is the latest incarnation of Bassett’s frames; GenVoca melds feature modularity with compositional programming. Both approaches explicitly rest on a pair of ideas: (1) parameterized functions return source code and (2) composing such functions synthesizes applications. Altho...
