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...

in this study, a one-dimensional model called dyresm was used to simulate the thermal structure and artificial destratification of 15-khordad reservoir over a period of one year. the simulation showed that the reservoir is warm monomictic and is stratified during 210 days of the simulation year. the model reproduced the temperature of the meta- and hypolimnion very close to the observed data, b...

With construction of new large-scale water storage projects on the wane in the U.S. and other developed countries, attention must focus on improving the operational effectiveness and efficiency of existing reservoir systems for maximizing the beneficial uses of these projects. Optimal coordination of the many facets of reservoir systems requires the assistance of computer modeling tools to prov...

Abstract Reservoir computing (RC) offers efficient temporal data processing with a low training cost by separating recurrent neural networks into fixed network connections and trainable linear network. The quality of the network, called reservoir, is most important factor that determines performance RC system. In this paper, we investigate influence hierarchical reservoir structure on propertie...

Abstract This paper shows that the celebrated embedding theorem of Takens is a particular case much more general statement according to which, randomly generated linear state-space representations generic observations an invertible dynamical system carry in their wake phase space dynamics into chosen Euclidean state space. coincides with natural generalized synchronization arises this setup and...

The solution of sparse linear systems is the most time-consuming step in running reservoir simulations; over 70% of time is spent on the solution of linear systems derived from the Newton methods [1]. If large highly heterogeneous reservoir models are applied, their linear systems are even harder to solve and require much more simulation time. Hence fast solution techniques are fundamental to l...

in this paper, time-domain dynamic analysis of dam - infinite reservoir is studied. a numerical method, discrete singular convolution (dsc), which seems to be efficient and simple, has been used to model the mixed boundary conditions. after a brief introduction, dsc is applied to model the equation of motion of fluid-structure with constant cross section subjected to el-centro (1940) earthquake...

We extend the non-Markovian quantum state diffusion (QSD) equation to open quantum systems which exhibit multi-channel coupling to a harmonic oscillator reservoir. Open quantum systems which have multi-channel reservoir coupling are those in which canonical transformation of reservoir modes cannot reduce the number of reservoir operators appearing in the interaction Hamiltonian to one. We show ...
