Deriving Composite Functions as Activation Function for Neural Networks or for Wavenets
Bushra
Hussien Aliwi
This study present new idea in way to more future wonderful ideas, exploiting mathematical side of specific, through several ways employing very wide resources of mathematical functions and their properties that with natural in improve features of activation function, from these studies this study which drive an activation function through compose two (and more) functions with properties to be continuous and drivable.
We can drive membership function under fuzzy logic by this as composite function on wavelet function or vice versa, and for many different functions (as future work).
Also there idea to compose wavelets from families such SLOG mother wavelets with RASP or POLYWOG wavelets, that specifically arises from NNs representation and classification problems ,which also drivable .Each one from these functions have derivative which also can be composed to get an other activation function .

Fatma
Kamil Majeed Al-Basri
: In this paper, we study the convergence of nets in convex bornological vector space and the related concepts and investigate some properties of them. We study the relationship between the convergence net in bornological space and topological space in which we explain the convergence net in bornological space be convergent in topological space. After that we apply the conditions on the contrary to be valid through the properties which explain that.

Aqeel
Mohammed Hussain
In this paper we have studied the composition operator induced by the automorphism σ and discussed the adjoint of the composition of the symbol σ.We have look also at some known properties on composition operators and tried to see the analogue properties in order to show how the results are changed by changing the function σ on U.
In order to make the work accessible to the reader, we have included some known results with the details of the proofs for some cases and proofs for the properties .

Enhancing the Security of Playfair Cipher by Stream Cipher
Fairouz
Mushtaq Sher Ali
Cryptography is a science of converting clear message into secret message "nonreadable message",where message was encrypted at sender side then decrypted at receiver side. Playfair is an example of substitution cipher,it has various limitations, inthis paper we proposean advanced encryption algorithm which improves the security of Playfair method by combining it with modern cipher method like Stream cipher, Stream cipher relatively regards as unbreakable method, and bit oriented method (instead of character-oriented) where the Plaintext, Ciphertext and the Key are strings of bits.
When applying the proposed algorithm, we see that the mentioned above combination cipher has a high degree of security, where cipher based on just Playfair method is not secure. Also the proposed algorithm makesthe cryptanalysis more difficult.

Modify Initialization k-means Clustering Algorithm to Generate Initial Centroids
Lamia
AbedNoor Muhammed
K-means is one of the most common clustering techniques used with numeric data. Different issues are conducted in k-means algorithm in order to reach the optimum solutions with best situations, weather producing good results or the ways used to produce the results efficiently. Initial centroids of this algorithm play important role, so the generation initial centroids attracting more work. However, this paper aims to discuss a new proposed step to improve the generation of initial centroids i.e. modification the first iteration of k-means algorithm. The experiment work of this paper would be applied with one of the famous data that is "iris", this data is suited with k-means algorithm. The experiments were tested with the origin k-means algorithm in two parameters: "execution time" and "cost function" that is represented by sum square error SSE. The results are promise work with this modification

A comparison among methods for estimation of the parameter of the Maxwell- Boltzmann distribution using simulation
Layla
Matter Nassir
The Maxwell or Maxwell- Boltzmann distribution was invented to solve problems related to physics, chemistry and plays an important role in and other allied sciences. So in this paper Bayesian using special priorinformation for estimating the scale parameter of Maxwell distribution, the maximum likelihood estimation andthree different types of moments are presented for this. The simulation by matlab program is used to compare these estimators with respect to the Mean Square Error (MSE) and Mean Absolute Percentage Error (MAPE), the results of comparison showed that for all the varying sample size, the estimators of Bayes method with special prior distribution is followed by the Maximum likelihood estimatorhas smaller MSE and MAPE compared to others, and in all cases the statistical hypotheses had been satisfied for both methods the MSEand MAPE decrease as sample size increases.

Hamid
The main aim of this research is to evaluate the value of double integrations whose integrands continuous function numerically by using rule (this rule compound from Simpson‘s rule on the exterior dimension Y and Mid point rule on the interior dimension X) when the number of subintervals on the interior dimension equal to the number of subintervals on the exterior dimension , that is mean where as means the distances between ordinates on the X-axis and means the distances between ordinates on the Y-axis . And to improve the results we applied Aitken‘s acceleration over the Yielded values from the SM rule to accelerate the convergence of the approximate to the real value of integrations and we named this method (ASM) and we got good resulte with respect to the accuracy and speed of convergence to the analytic ( real ) values by using little subintervals.

Safaa
Mahdi Muosa AL-Gasas
The main aim of this paper is to evaluate the triple integrals with continuous integrands numerically by using two method obtained from two accelerations Aitken‘s and Romberg with the combination rule from( two rules Mid- point rule on both two dimensions of exterior Z and middle dimension Y and Simpson‘s rule on the interior dimension X, denoted by MMS) where the number of divisions on the exterior dimension is equal to the number of divisions on the middle dimension and equal to the number of divisions on the interior dimension where we have introduced theorem with proof to find this rule and the correction error bounds with respect its and to improve the results we used two accelerations mentioned with rule MMS and we shall call these two methods AI(MMS) and RO(MMS) where we got high accuracy in the results by few subintervals relatively and short time .
