Delay and throughput trade-off in WiMAX mesh networks

We investigate WiMAX mesh networks in terms of delay and throughput trade-off. For a given topology, using our proposed analytical model we study how slot allocation policy and forwarding probability affects per-node and network performance.

Skin fibrosis, internal organ involvement and auto antibodies in systemic sclerosis: longitudinal development and impact on survival

Popular Abstract in Swedish Hudfibros, inre organengagemang och autoantikroppar vid systemisk skleros: longitudinell utveckling och effekt på överlevnad. Systemisk skleros kallas ofta för sklerodermi. Sjukdomen tillhör de systemiska bindvävssjukdomarna och handläggs i Sverige oftast av reumatologer. Kardinalsymtomet vid sklerodermi är förhårdnad hud vilket gett sjukdomen den dess namn. Sklero betySystemic sclerosis (SSc) is a connective tissue disease with a highly variable prognosis. Since new treatment strategies are emerging, there is a need for prognostic markers in order to help allocate patients to the optimal treatment. When comparison is made to the general population, there is an increased mortality rate in this study, both in the series as a whole and in the subgroups of men and

Very easily decodable nonlinear cyclic codes

A class of nonlinear binary cyclic codes of length n=m2m, constant weight w=m2m-1, and minimum distance dmin=2m, with M=n codewords for every m⩾2 is introduced. The decoding computation is shown to be equivalent to performing two correlations of fixed sequences with the received word

Inference for Non-linear Diffusions and Jump-Diffusions: A Monte Carlo EM approach

We propose a simple, general and computationally efficient algorithm for maximum likelihood estima- tion (MLE) of parameters in diffusion and jump-diffusion processes. This is conducted within a Monte Carlo EM-algorithm, where the smoothing distribution is computed using resampling. The results are encouraging as we can approximate the MLE well for the models studied when using simulated data. We
