In the given algorithm, we propose a development to the evaluations of Newton's numerical
algorithm. Derivation of the standard method (Newton Raphson method) involves first
derivative of the function. It is shown that the number of iterations of the new method is six
and determined results support this technique. The results obtained show that the new
proposed method is more accurate, easy to use, and efficient than other numerical methods
are indicated

Several numerical formulas have been introduced and analyzed in this paper. Based on the
initial value x_0 used with each methods; these methods is used for solving the nonlinear
equation of PV cell (single-diode). Several experiments are employed in order to examine
these methods. Comparison of the results acquired in terms of number of evaluations reveal
promising application of the proposed new method for nonlinear examples.

For the last years, the various of Newton's formula have become common iterative numerical
techniques to realize approximate solutions to the zeros of nonlinear equations of PV cell
(single diode) model foe electronic applications. These techniques do not necessitate the
computation of second derivative of the functions but it need only first derivative of it's
functions. In this paper, we introduce a new proposed method Dekker's Formula with five
evaluations per iterations based on Accelerated Predictor-Corrector Halley's method.
Numerical experiments produce that the new algorithm can determine with the standard
Newton's algorithm.

In this paper, an efficient new fashion is suggested to improve two-step iterative method. A
new three step iterative method for solving nonlinear equations of a photovoltaic cell based
on Newton's method has been introduced. The accuracy and efficiency of the proposed
method has been carried out using numerical experiments. The absolute error of the
proposed and standard ones has been analyzed too. per iterations; the suggested method
have lesser number of evaluations than the standard one.

In this work, two iterative methods is proposed and described here for solving nonlinear
equation of PV cell device. The type of solar cell is single diode model based on its equivalent
circuit with various values of load resistance R. These methods do not require second order of
derivative and easy to use. The convergence of the proposed method do not discussed here. In
order to found the accuracy and efficiency of the proposed and other method, the absolute
error value have been calculated and compared. The advantages of the new proposed method
can be investigated by comparing with the Improved Hornor-Newton method; and the results
obtained indicate that the propose method is more accurate, efficient and easy to use than the
second method.

During the two last decades ago, audio compression becomes the topic of many types of research due to the importance of this field which reflecting on the storage capacity and the transmission requirement. The rapid development of the computer industry increases the demand for audio data with high quality and accordingly, there is great importance for the development of audio compression technologies, lossy and lossless are the two categories of compression. This paper aims to review the techniques of the lossy audio compression methods, summarize the importance and the uses of each method.
