A NOVEL IHS-GA FUSION METHOD BASED ON ENHANCEMENT VEGETATED AREA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 Pan sharpening methods aim to produce a more informative image containing the positive aspects of both source images. However, the pan sharpening process usually introduces some spectral and spatial distortions in the resulting fused image. The amount of

Sharpened Bonferroni Inequalities
Journal of Combinatorial Theory, Series B, 1993 In this paper a \(k\)-uniform hypergraph \(H\) with vertex set \(S\) is said to be sparse if for each \(I\subseteq S\), the induced partial hypergraph \(H_ I=(I,\{e\in E(H)| e\subseteq I\})\) has at most \({| I|- 1\choose k-1}\) edges. The reviewer sharpened Bonferroni inequalities by including an additional term determined by a \(k\)-hypertree \(H ...

On sharpening of an inequality of Turán
Applicable Analysis and Discrete Mathematics, 2019 Let P(z) = ?nv=0 avzv be a polynomial of degree n. Then as a generalization of a well-known result of Tur?n [18], it was proved by Govil [5] that if P(z) is a polynomial of degree n having all its zeros in |z| ? K, K ? 1, then (0.1) max |z|=1 |P'(z)|? n/1+Kn max |z|=1 |P(z)|. In this paper, we prove a polar derivative generalization of this

Advanced Functional Materials, EarlyView.Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

Sharpening the Microtome Knife [PDF]
Nature, 1954 SEVERAL articles have been written on the most suitable method of sharpening the knife of a microtome. The usual manner of sharpening is grinding, honing, polishing and stropping, and there are several different methods for each of those operations. There is obviously a lack of a quantitative measuring method by means of which the result of different ...

Advanced Functional Materials, EarlyView.Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Advanced Functional Materials, EarlyView.An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...
