It is shown that there is a trade-off between the smoothness and decay properties of the dual functions, occurring in the lattice expansion problem. More precisely, it is shown that if g and g areâ€¦ (More)

Random-access networks may exhibit severe unfairness in throughput, in the sense that some nodes receive consistently higher throughput than others. Recent studies show that this unfairness is due toâ€¦ (More)

We apply a new corrected diffusion approximation for the Erlang C formula to determine staffing levels in cost minimization and constraint satisfaction problems. These problems are motivated by largeâ€¦ (More)

This paper proposes a method to estimate the Integral Non-Linearity of AD-converters from the lower order output Fourier coeficients of a sinusoidal input. In order to get a high quality estimate,â€¦ (More)
