Limitations on water resources and the high costs of new hydraulic structure construction intensify the need for an optimum operation of Iranian reservoir systems. For appropriate water distribution and management in a 9-reservoir system on the Kalamarz river, Mianeh basin optimizing mathematical models are applied. Considering the stochastic nature of river discharges and the constant amount o...

We prove that maximum weight branchings in directed graphs can be approximated in time O(m) up to a factor of 1− ǫ, where ǫ > 0 is an arbitrary constant.

In signal analysis, the joint estimation of the time-scale parameters which can affect a known signal (Doppler effect or scale effect, delay. . . ) may be a problem of interest. An important result has shown that, even if the quality of the time delay estimation is classically given by the inverse spread of the signal spectral density, the quality of the scale estimation only depends on the inv...

New emerging space-time processing technologies promise a significant performance increase of wireless communication systems. The particular application and scenario strongly influences the amount of possible performance and capacity increase if antenna arrays are deployed at the basestation (BS) and/or at the mobile terminal (MT). The achievable gain is mainly determined by the spatial correla...
