abstract prediction of input flow into water resources is regarded as one of the most important issues in optimum planning and management in producing electro-water energy and optimum allocation of water into different consumption sources. different parameters affect on input discharge into dams. climate variables including temperature and rainfall have the most effect on input runoff rate to w...

In the history of gold market, contemporary prices are higher than previous values, and current market is highly non-linear unpredictable. Gold most popular precious metal for investment out all metals. The like other markets, vulnerable to speculation volatility. has served as a secure base in several countries when compared metals used investment. this study, we suggest time series model pred...

Single crystals of the title compound, aluminium niobium triphosphate, Al(0.5)Nb(1.5)(PO(4))(3), have been synthesized by a high-temperature reaction in a platinium crucible. The Al(III) and Nb(V) atoms occupy the same site on the axis, with disorder in the ratio of 1:3. The fundamental building units of the title structure are isolated Al/NbO(6) octa-hedra and PO(4) tetra-hedra (. 2 symmetry),...

One of the main tasks to analyze and design a mining system is predicting the behavior exhibited by prices in the future. In this paper, the applications of different prediction methods are evaluated in econometrics and financial management fields, such as ARIMA, TGARCH, and stochastic differential equations, for the time-series of monthly copper prices. Moreover, the performance of these metho...

This paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. System engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (TCO...

The effects of developing technology and rapid population growth on the environment have been expanding gradually. Particularly, in water consumption has revealed necessity management. In this sense, accurate flow estimation is important to Therefore, study, a grey wolf algorithm (GWO)-based gated recurrent unit (GRU) hybrid model proposed for streamflow forecasting. daily data Üçtepe Tuzla obs...
