A frame in an n-dimensional Hilbert space Hn is a possibly redundant collection of vectors {fi}i∈I that span the space. A tight frame is a generalization of an orthonormal basis. A frame {fi}i∈I is said to be scalable if there exist nonnegative scalars {ci}i∈I such that {cifi}i∈I is a tight frame. In this paper we study the combinatorial structure of frames and their decomposition into tight or...

In this paper, the seismic performance of reinforced concrete moment-resisting frame with cold-joint subjected to monotonic lateral load has been studied numerically using Pushover analysis. Two modes fracture may occur for in a in-plane loading. The are Mode-I (stress orthogonal local plane crack surface) and Mode-II parallel surface but front). order model verify its behavior mode I II mechan...

We develope a local theory for frames on finite dimensional Hilbert spaces. We show that for every frame (fi) m i=1 for an n-dimensional Hilbert space, and for every ǫ > 0, there is a subset I ⊂ {1, 2, . . . ,m} with |I| ≥ (1 − ǫ)n so that (fi)i∈I is a Riesz basis for its span with Riesz basis constant a function of ǫ, the frame bounds, and (‖fi‖) m i=1 , but independent of m and n. We also con...

Discriminative segmental models, such as segmental conditional random fields (SCRFs), have been successfully applied to speech recognition recently in lattice rescoring to integrate detectors across different levels of units, such as phones and words. However, the lattice generation has been constrained by a baseline decoder, typically a frame-based hybrid HMMDNN system, which still suffers fro...

localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. despite development of many techniques including angiography, mri, sonography, and frame base stereotaxy, a more accurate localizing technique is still needed (1, 2). a step forward to achieve this goal is to develop a navigation system. in this manuscript, we explained so...

The continuous rigid frame bridges are more sensitive to wind action with the increase of bridge span and pier height. In order to calculate the wind induced buffeting responses, the fluctuating wind field at bridge site are simulated by harmonic synthesis method and the wind loads are also derived based on the simplified quasi-steady theory, the time-history dynamic responses of the bridge are...

Pulsed dye laser (PDL) is an effective treatment for port- wine stain and can cause some short- term and long- term side- effects. Pyogenic granoluma is one of its late- onset adverse effects. Herein, we present two cases of pyogenic granoluma following treatment of port- wine stain with PDL.

Visual-spatial impairment is a fundamental disorder in cerebral palsy (CP). However, current spatial testing is restricted to reaching space, whereas navigational space is seldom assessed. The Magic Carpet test, derived from the Corsi Block-tapping Task (CBT) for visual-spatial memory, is a new developmental test for navigation. The performances of the Magic Carpet test and CBT were assessed in...
