Especially for drought periods, the higher the accuracy of reservoir inflow forecasting, the 9 more reliable the water supply from a dam. The article focuses on probabilistic forecasting of 10 seasonal inflow to reservoirs and determines estimates from the probabilistic seasonal inflow 11 according to drought forecast results. The probabilistic seasonal inflow was forecasted by a copula12 based...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
Stock price forecasting models with lower Mean Squared Error (MSE) are more “welcome" than those who have higher MSE. However, this “welcome" may disappear when lower MSE leads to an unexpected loss whereas higher MSE leads to a positive profit in a practical investment. The reason is that MSE aims to evaluate models in the view of “accuracy", which has nothing to do with profit. We therefore p...
The theory of grey system is used when sufficient information of the community under study is not in hand. The grey forecast model is proper when the information variety is fix and certain. Grey model can apply some additional computations to improve forecasting activities when data is insufficient. Through using improved grey model, the assessment error decreases significantly. This study made...
In overloaded Massive MIMO (mMIMO) systems, wherein the number K of user equipments (UEs) exceeds base station antennas M, it has recently been shown that non-orthogonal multiple access (NOMA) can increase sum spectral efficiency. This paper aims at identifying cases where code-domain NOMA improve efficiency mMIMO in classical regime <; M. Novel expressions are provided for uplink and downlink ...
the main objective in the present study was to assess the spatial variation of chemical and physical soil properties and then use this information to select an appropriate area to install a pasture rehabilitation experiment in the zereshkin region, iran. a regular 250 m grid was used for collecting a total of 150 soil samples (from 985 georeferenced soil pits) at 0 to 30, and 30 to 60 cm layers...
One of the problems of the banking system is cash demand forecasting for ATMs (Automated Teller Machine). The correct prediction can lead to the profitability of the banking system for the following reasons and it will satisfy the customers of this banking system. Accuracy in this prediction are the main goal of this research. If an ATM faces a shortage of cash, it will face the decline of bank...
In a previous work a random matrix average for the Laguerre unitary ensemble, generalising the generating function for the probability that an interval (0, s) at the hard edge contains k eigenvalues, was evaluated in terms of a Painlevé V transcendent in σ-form. However the boundary conditions for the corresponding differential equation were not specified for the full parameter space. Here this...
