Multicomponent analysis attempts to simultaneously predict the ingredients of a mixture. If near-infrared spectroscopy provides the predictor variables, then modern scanning instruments may offer absorbances at a very large number of wavelengths. Although it is perfectly possible to use whole spectrum methods (e.g. PLS, ridge and principal component regression), for a number of reasons it is of...

Wavelength selection in reaction-diffusion systems can be understood as a coarsening process that is interrupted by counteracting processes at certain wavelengths. We first show mass-conserving driven self-amplifying mass transport between neighboring high-density domains. derive general criterion and generically uninterrupted two-component conserve mass. The theory then generalized to study an...

This paper proposes a replica selection and downloading scheme in λ-grid networks. In λ-grid networks, in order to distribute loads and achieve high performance computing, a large amount of data is replicated on storage servers as files, and clients download these replicas. To download replicas efficiently, an appropriate replica selection scheme which avoids wavelength contention is required b...
