A sharpness dependent filter for mesh smoothing
In this paper, we propose a sharpness dependent filter design based on the fairing of surface normal, whereby the filtering algorithm automatically selects a filter. This may be a...

Wavelength assignment to lightpaths for minimal wavelength conversions in multihop WDM networks
In multihop wavelength division multiplexing systems, a connection between two communication nodes consists of one or more lightpaths. A wavelength conversion is required at the j...

The load rebalancing problem
In the classical load balancing or multiprocessor scheduling problem, we are given a sequence of jobs of varying sizes and are asked to assign each job to one of the m empty proce...
