Most heteroassociative memories models intend to achieve the recall of the entire trained pattern. The Alpha-Beta associative memories only ensure the correct recall of the trained patterns in autoassociative memories, but not for the heteroassociative memories. In this work we present a new algorithm based on the Alpha-Beta Heteroassociative memories that allows, besides correct recall of some...

appropriate function of active management in common investment funds function depend on factors such as diversification, identification papers unrealistic pricing, market timing, and so on. market timing are include changing the portfolio investment funds and market indices such as short-term bonds and make an asset depends on whether the market is expected in the whole of the assets to make be...

it is well known that the matrix exponential function has practical applications in engineering and applied sciences. in this paper, we present some new explicit identities to the exponential functions of a special class of matrices that are known as central-symmetric $x$-form. for instance, $e^{mathbf{a}t}$, $t^{mathbf{a}}$ and $a^{mathbf{a}t}$ will be evaluated by the new formulas in this par...

In this paper, the fast synchronization problem of 5D Hindmarsh–Rose neuron networks is studied. Firstly, global predefined-time stability a class nonlinear dynamical systems investigated under complete beta function. Then an active controller via backstepping design proposed to achieve two in which time each state variable master-slave different and can be defined advance, respectively. To sho...

Background: The formalism recommended by Task Group 60 (TG-60) of the American Association of Physicists in Medicine (AAPM) is applicable for β sources. Radioactive biocompatible and biodegradable 153Sm glass seed without encapsulation is a β- emitter with a short half life and delivers a high dose rate to the tumor in the millimeter range. In this work the dosimetry parameters of the ...

We introduce a new five-parameter distribution called the beta exponentiated Gumbel (BEG) distribution that includes the beta Gumbel, exponentiated Gumbel and Gumbel distribution. Expressions for the distribution function, density function and rth moment of the new distribution and order statistics are obtained. We discuss estimation of the parameters by maximum liklelihood ...

We propose an exact method for generating random deviates from continuous order statistics. This versatile method that generates Beta deviates as a middle step can be applied to any density function without resorting to numerical inversion. We also conduct an exhaustive investigation to document the merits of our method in generating deviates from any Beta distribution.
