in this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (lims). dynamical equations of lim have been considered accurate. in other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. then equations of the reference model and adaptive mode...

land use optimization is one of the appropriate methods for soil conservation which helps decision makers and watershed planners in order to make the optimum decision among different land uses. the main objective of this research was to find the optimum area of each land use to reduce soil erosion rate as well as to increase the income of stakeholders in golroudbar watershed located in semnan p...

the purpose of this paper is to studying nonlinear k-ε turbulence models and its advantages in internal combustion engines, since the standard k-ε model is incapable of representing the anisotropy of turbulence intensities and fails to express the reynolds stresses adequately in rotating flows. therefore, this model is not only incapable of expressing the anisotropy of turbulence in an engine c...

A -expectation tolerance interval procedure is derived from the concept of generalized pivotal quantity, which has been frequently used to obtain confidence intervals in situations where standard procedures do not lead to useful solutions. The proposed procedure can be applied to general balanced mixed linear models. Some practical examples are given to illustrate the proposed procedure. In add...

A simplified method for characterization of standard library cells based on the linear delay model is presented in this paper. The linear model is chosen as it allows rapid characterization with a modest number of simulations, while achieving acceptable accuracy. All the parameters of cell delays are defined as 50%-to-50% delays, as distinguished from 50%-to-threshold or threshold-to-50% often ...
