In this paper we study the continuous dynamical sampling problem at infinite time in a complex Hilbert space H. We find necessary and sufficient conditions on bounded linear operator A∈B(H) set of vectors G⊂H, order to obtain that {etAg}g∈G,t∈[0,∞) is semi-continuous frame for if it possible discretize variable t still have also relate iteration etA G discrete (A′)n G′ an adequate A′ G′⊂H.

1.2. Primer on Connections. Recall from Peng’s talk that a connection on P → X can be thought of in three ways: (1) As a field of horizontal subspaces: TpP = HpP⊕VpP , where V P = ker (π∗). (Note that Vp ∼= g, and Hp ∼= Tπ(p)X). (2) As a g-valued 1-form A ∈ ΩX (g) which is invariant w.r.t. the induced G-action on ΩX (g). (3) Given a representation of G on W , as a vector bundle connection on th...

Title of dissertation: FRAME MULTIPLICATION THEORY FOR VECTOR-VALUED HARMONIC ANALYSIS Travis D. Andrews, Doctor of Philosophy, 2014 Dissertation directed by: Professor John J. Benedetto Department of Mathematics A tight frame Φ is a sequence in a separable Hilbert space H satisfying the frame inequality with equal upper and lower bounds and possessing a simple reconstruction formula. We define...

When making investment decisions, people rely heavily on price charts displaying the past performance of an asset. Price can come with any time frame, which provider might strategically choose. We analyze impact frame retail investors’ behavior, particularly trading activity and risk-taking, in a controlled experiment 1041 investors. find that shorter frames are associated more activity, result...

The G.722 wideband speech codec offers higher quality and better naturalness than G.711, is low in complexity, has low delay, and tandems well with other codecs. This makes it an attractive codec for Voice over IP and Voice over Wireless LANs. However, loss of a G.722 coded speech frame results in a mismatch of the encoder/decoder states that affects the decoding of subsequent correctly receive...

We introduce the notion of a g-atomic subspace for bounded linear operator and construct several useful resolutions identity on Hilbert space using theory g-fusion frames. Also we shall describe concept frame pair Bessel sequences some their properties.

LR-WPANs have two types of networks: beacon–enabled and non-beacon-enabled networks. In beacon-enabled LR-WPANs, the high reliability of Beacon frame transmission is required because all transmissions is controlled by the in-formation in the Beacon frame. However, the process to handle the case for the beaconloss is not well-defined in the standard. In this paper, an enhanced protocol for the c...

A network covert channel is a passage along which information leaks across the network in violation of security policy in a completely undetectable manner. This paper reveals our findings in analysing the principle of G.723.1 codec that there are ‘unused’ bits in G.723.1 encoded audio frames, which can be used to embed secret messages. A novel steganalysis method that employs the second detecti...

The measurement of the polarized gluon distribution function ∆G/G using currenttarget correlations in the Breit frame of deep inelastic scattering is proposed. The approach is illustrated using a Monte Carlo simulation of polarized ep-collisions for HERA energies.
