Abstract—Graph-based ranking models have been widely applied in information retrieval area. In this paper, we focus on a well known graph-based model - the Ranking on Data Manifold model, or Manifold Ranking (MR). Particularly, it has been successfully applied to content-based image retrieval, because of its outstanding ability to discover underlying geometrical structure of the given image d…
a b s t r a c t Activated carbons with high volumetric capacitance are prepared from apricot shell by optimizing the carbonization temperature prior to NaOH activation to balance the porosity and density. The carbonization temperature has a marked effect on both the pore structure and the electrochemical performances of the activated carbons. As the carbonization temperature increases, the …
Abstract. Nitrogen-doped porous carbons are very simply prepared by direct pyrolysis of a nitrogen-containing organic salt, the tetrasodium salt of ethylenediamine tetraacetic acid for example, at 600–900 ◦C in an inert atmosphere without activation. The porosity and surface chemistry of the carbon depend strongly on the pyrolysis temperature. The surface area and pore volume increase w…
