Recursive spectral bisection (RSB) is a heuristic technique for finding a minimum cut graph bisection. To use this method the second eigenvector of the Laplacian of the graph is computed and from it a bisection is obtained. The most common method is to use the median of the components of the second eigenvector to induce a bisection. We prove here that this median cut method is optimal in the se...

One of the major shortcomings existing image dehazing algorithms is in estimating scene transmittance, which has assumed many items algorithms. key assumption been pixel uniformity and smoothness. In this paper, we propose to solve problem using a combination single-pass CNN with graph cut It considers transmittance based on differential pixel-based variance, local global patches energy functio...

A new Faustmann optimal rotation harvesting stands’ problem under Brown geometric price and Logistic and Gompertz wood stock, diffusions is presented. The optimal cut policies for the stochastic Faustmann model and the single harvest rotation or Vicksell model are evaluated in the case of a Chilean Radiata pine forest company. The company cut policy validates the Vicksell model, its optimal cut...

Pyrolysis and/or piranha treatment of fluorinated /ozonated single-walled carbon nanotubes (SWNTs) were found to have cut the nanotubes to short length (~100nm). Pyrolysis of partially fluorinated SWNTs (~C5F) at 700°C cut the nanotubes without causing significant crosslinking among the SWNTs. When pyrolyzed at lower temperatures, the fluorinated SWNTs need room temperature piranha treatment to...
