Image denoising is the principle problem of image restoration and many scholars have been devoted to this area and proposed lots of methods. In this paper we propose modified feature restoration algorithm based on threshold and neighbor technique which gives better result for all types of noise. Because of some limits of conventional methods in image denoising, several drawbacks are seen in the...

We present a rapid, simple, and scalable approach to achieve superhydrophobic (SH) substrates directly in commodity shrink wrap film utilizing Argon (Ar) plasma. Ar plasma treatment creates a stiff skin layer on the surface of the shrink film. When the film shrinks, the mismatch in stiffness between the stiff skin layer and bulk shrink film causes the formation of multiscale hierarchical wrinkl...

Polyolefins are finding increased popularity in microfluidic applications due to their attractive mechanical, processing, and optical properties. While intricate features are typically realized in these thermoplastics by hot embossing and injection molding, such fabrication approaches are expensive and slow. Here, we apply our shrink-induced approach-first demonstrated with polystyrene 'Shrinky...

the purpose of this paper is to study the convergence and the almost sure t-stability of the modied sp-type random iterative algorithm in a separable banach spaces. the bochner in-tegrability of andom xed points of this kind of random operators, the convergence and the almost sure t-stability for this kind of generalized asymptotically quasi-nonexpansive random mappings are obtained. our resu...

Nowadays, transistor technology is going toward the fully depleted architecture; the bulk transistors are becoming more complex in manufacturing as the transistor size is becoming smaller to achieve the high performance especially at the node 28 nm. This is the first of two papers that discuss the basic drawbacks of the bulk transistors and explain the two alternative transistors: 28 nm UTBB FD...

Wehave read the studyof Lapennaet al.with great interest [1]. We think that these techniques are not compatible with the co-aptation physiology. Our concerns are as follows. If we apply the clover technique to a normal (without regurgitation) tricuspid valve, would this create an insufficiency? Yes, it would. This is because the free edges of the leaflets could not adapt to changes in filling a...

Symbolic PDBs and Merge-and-Shrink (M&S) are two approaches to derive admissible heuristics for optimal planning. We present a combination of these techniques, Symbolic Merge-and-Shrink (SM&S), which uses M&S abstractions as a relaxation criterion for a symbolic backward search. Empirical evaluation shows that SM&S has the strengths of both techniques deriving heuristics at least as good as the...

This article discusses estimation of a heteroscedastic multivariate normal mean in terms of the ensemble risk. We first derive the ensemble minimaxity properties of various estimators that shrink towards zero. We then generalize our results to the case where the variances are given as a common unknown but estimable chi-squared random variable scaled by different known factors. We further provid...

abstract leafy vegetables such as lettuce are more susceptible to post harvest losses, thus application desirable treatments can be recommendable. generally, type of packaging, such as modified atmosphere packaging (map) and wrapping can considerably suppress post harvest loss of horticultural products. in this study, the effects of polypropylene film (thickness 30 and 40 micron) wrapping and m...

The purpose of this study was to show the effectiveness of die shrink as a package solution for memory devices. In the case of the 8mm x 10mm Direct Rambus DRAM device, about 350 dies can be obtained from a single 8-inch wafer. The 85% linear shrink (15% shrink in both x and y-directions) allows an additional 150 dies from the same size wafer. This simple calculation explains the importance of ...
