In this paper, we propose a heuristic multicast routing algorithm, which minimizes the cost while satisfying both the wavelength required and hop length selection. The algorithm consists of two subproblems: the wavelength assignment & the routing path selection. For solving the wavelength assignment subproblem, an auxiliary graph is created where by the nodes and the links in the original netwo...

This article presents an active wavelength selection algorithm for multicomponent analysis with tunable infrared sensors. Traditional techniques for wavelength selection operate off-line; as a result, the resulting feature subset is fixed and only optimal for the specific mixtures and noise levels in the training set. To address this limitation, the proposed algorithm interleaves the wavelength...

2014 We consider axisymmetric cellular structures, as concentric rolls occurring in Rayleigh-Bénard thermoconvection when forcing a roll at an outer circular boundary. We show that under these circumstances a unique wavenumber is selected. It corresponds to the vanishing of the coefficient of perpendicular diffusion (D~ = 0). This condition expresses simply the fact that the rolls can be both b...
