we present an application of the dual gabor frames to image processing. our algorithm is based on finding some dual gabor frame generators which reconstructs accurately the elements of the underlying hilbert space. the advantages of these duals constructed by a polynomial of gabor frame generators are compared with their canonical dual.
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
s: Aim: The aim of this research work was to compare and evaluate the hardness and flexural strength of three different commercially available fixed provisional restorative resins. Objective: The objectives of this research work are, to assess whether setting mechanism of fixed provisional restorative resins has an effect on the physical and mechanical properties and to compare and contrast the...
These studies define a new mechanism-based approach to radiosensitize tumor cure by single dose radiotherapy (SDRT). Published evidence indicates that SDRT induces acute microvascular endothelial apoptosis initiated via acid sphingomyelinase (ASMase) translocation to the external plasma membrane. Ensuing microvascular damage regulates radiation lethality of tumor stem cell clonogens to effect t...
The aim of this study was to evaluate the Knoop hardness after 15 min and 24 h of different shades of a dual-cured resin-based cement after indirect photoactivation (ceramic restoration) with 2 light-curing units (LCUs). The resin cement Variolink II (Ivoclar Vivadent) shade XL, A2, A3 and opaque were mixed with the catalyst paste and inserted into a black Teflon mold (5 mm diameter x 1 mm high...
PURPOSE A number of provisional restorative materials exist on the market. This study tested marginal fit and color stability of three provisional restorative materials and a control. MATERIALS AND METHODS Two auto-cure materials, Protemp Garant and Integrity, and one dual-cure material, Luxatemp Solar, were tested against SNAP, a polyethyl methacrylate control. A maxillary right central inci...
Abstract Background: Although corneal graft may be rejected by the immune system of the recipient it remains as the most successful operation as compared to transplantation of other tissues. Since most patient do not reject the grafts, those who do are in the minority. This study was carried out to assess the usefulness of the cure frailty model for determining the significance of risk facto...
background: peritoneal dialysis is one of the most prevalent types of dialysis prescribed to the patients suffering from renal failure. studies on the factors affecting the survival of these patients have mainly used log-rank test and cox analysis. the present study aimed to investigate the risk factors affecting short- and long term survival of patients on continuous ambulatory peritoneal dial...
