Gabor Analysis in Weighted Amalgam Spaces
Amalgam spaces frames Gabor expansions Gabor frames modulation spaces phase-space sampling time-frequency analysis Walnut representation
2015/12/10
Gabor frames {e2πinβ·xg(x − kα)}n,k∈Zd provide series representations not only of functions in L2(Rd) but of the entire range of spaces Mν p,q known as the modulation spaces. Membership of a fun...
MULTI-WINDOW GABOR FRAMES IN AMALGAM SPACES
Wiener amalgam space Gabor frame Wiener’s Lemma
2015/12/10
We show that multi-window Gabor frames with windows in the Wiener algebra W(L∞, `1) are Banach frames for all Wiener amalgam spaces. As a by-product of our results we prove thecanonical dual of a Gabo...
INVERTIBILITY OF THE GABOR FRAME OPERATOR ON THE WIENER AMALGAM SPACE
Wiener amalgam space Gabor frame Walnut representation Wiener’s Lemma
2015/12/10
We use a generalization of Wiener’s 1/f theorem to prove that for a Gabor frame with the generator in the Wiener amalgam space W (L∞, `1 )(Rd), the corresponding frame operator is invertible on this s...

Dental Leakage Dental Restoration Permanent Dental Amalgam Compos-ite Resins
2009/12/15
Objective: The purpose of the present study was to assess the microleakage of composite restorations with and without a cervical amalgam base and to compare the results of dif-ferent composites and bo...
Comparison of microleakage in high copper spherical amalgam restorations using three different dentin bondin systems
Microleakage Dentin Bonding Amalgam
2009/12/11
Background and Aim: Amalgam is one of the mostly used restorative materials, but has some disadvantages. Microleakage is one of the short comings of amalgam which may lead to sensitivity and recurrent...

The effect of rebonding and liner type on microleakage of Class V amalgam restorations
Rebonding Amalgam restorations Microleakage
2009/12/7
Background and Aim: Application of varnish and dentin bonding agents can effectively reduce microleakage under amalgam restorations. Also rebonding may show some effects on microleakage and its compli...
