—Interleave division multiple access (IDMA) and orthogonal frequency division multiplexing – interleave division multiple access (OFDM-IDMA) have been proposed for beyond third...
This paper treats a new approach to the problem of periodic signal estimation. The idea is to model the periodic signal as a function of the state of a second-order nonlinear ordi...
We examine analytical and numerical aspects of optimal control problems for firstorder elliptic systems in three dimensions. The particular setting we use is that of divcurl syste...
We discuss an age-sex-structured population dynamics deterministic model taking into account random mating of sexes, females’ pregnancy and its dispersal in whole space. This mod...
This paper considers an infinite-server queue with multiple batch Markovian arrival streams. The service time distribution of customers may be different for different arrival strea...
