  • Forecasting Breast Cancer: A Study of Classifying Patients’
           Post-Surgical Survival Rates with Breast Cancer

    • Authors: Md Nurul Raihen; Sultana Akter
      Abstract: Breast cancer is the most lethal form of cancer that can strike women anywhere in the world. The most complex and tough undertaking in order to lower the death rate is the process of predicting a patient's likelihood of survival following breast cancer surgery. Due to the fact that this survival prediction is linked to the life of a woman, effective algorithms are required for the purpose of making the prognosis. It is of the utmost importance to accurately predict the survival status of patients who will have breast cancer surgery since this shows whether or not doing surgery is the actual approach for the specific medical scenario. Given the gravity of the situation, it is impossible to overstate how important it is to investigate new and improved methods of prediction in order to guarantee an accurate assessment of the patient's chances of survival. In this paper, we collect data and examine some models based on the survival of patients who underwent breast cancer surgery. The goal of this research is to evaluate the forecasting performance of various classification models, including the Linear regression model, logistic regression analysis, LDA, QDA, KNN, ANN, and Decision Tree. The results of the experiment on this dataset demonstrate the better performance of the came up with ANN approach, with an accuracy of 82.98 percent.

  • Using the Concept of Accessibility and Linear Programming to Measure and
           Select the Most Prominent Logistics Cities in Iraq

    • Authors: Foued Aloulou; KAREEM QASIM
      Abstract: In this research, we will address the importance of geographical location in relation to the supply chain and the process of choosing a location, relying on basic factors, and building a mathematical model using linear programming to choose the most important cities that have a high degree of connectivity (Accessibility) in Iraq from being economical or service distribution centers, either subsidiary or It has a high response speed and contributes to building a logistical transportation model in Iraq. The sports model, after the solution, has reached the selection of the best cities in terms of logistics.

  • On Absolute Valued Algebras Containing a Central Algebraic Element

    • Authors: Abdelhadi Moutassim
      Abstract: Let be an absolute valued algebra containing a nonzero central algebraic element. Then is a pre-Hilbert algebra and is finite dimensional in the following cases: 1) A satisfies (x, x, x)=0. 2) A satisfies (x2, x2 , x2 )=0. 3) A satisfies (x, x2, x)=0. In these cases is isomorphic to or . It may be conjectured that every absolute valued algebra containing a nonzero central element is pre-Hilbert algebra.

  • δ-small submodule and prime modules

    • Authors: Bashaer Ahmad; Majid Mohammed Abed
      Abstract: In this paper, we introduced and studied δ-small submodule over prime module. Two concepts are very important namely strongly prime submodule and completely prime submodule. Multiple results led to obtaining a δ-small submodule of a singular, divisible and Bezout module with R is local. Important terms that appeared in this article, together with some terms, produced the submodule that we were interested in.

  • On Absolute Valued Algebras with a Central Algebraic Element and
           Satisfying Some Identities

    • Authors: Abdelhadi Moutassim
      Abstract: In [8], we have proven that if  is an absolute valued algebra containing a nonzero central algebraic element, then  is a pre-Hilbert algebra. Here we show that    is finite dimensional in the following cases: 1) A satisfies  (x2, x, x) = 0 or (x, x, x2) = 0, 2) A satisfies  (x2, x2, x) = 0 or (x, x2, x2) = 0, . In these cases  A is isomorphic to R, C, H or O.

  • A Hybrid Analytical Approximate Technique for Solving Two-dimensional
           Incompressible Flow in Lid-driven Square Cavity Problem

    • Authors: Maysoon Hatem; A.S.J. Al-Saif
      Abstract: This paper suggests a new technique for finding the analytical approximate solutions to two-dimensional kinetically reduced local Navier-Stokes equations. This new scheme depends combines the q-Homotopy analysis method (q-HAM) , Laplace transform, and Padé approximant method. The power of the new methodology is confirmed by applying it to the flow problem of the lid-driven square cavity. The numerical results obtained by using the proposed method showed that the new technique has good convergence, high accuracy, and efficiency compared with the earlier studies. Moreover, the graphs and tables demonstrate the new approach’s validity.

  • A New View on Length Module

    • Authors: Mohammed Sabah Radwan; Marrwa Abdallah Salih, Majid Mohammed Abed
      Abstract: This paper consists of several new results about Length property of the module M. F-length of any Module comes from several concepts like Neotherian module and Artinian modules (Neo and Art) with comp- sition series. We proved that any Neo -module has submodule T and Neo -module is F-length. This implies that T also has F-length Property. Finally, some remarks, examples and definitions have been presented in this paper.

  • Optical Solitons in Fiber Bragg Gratings for Fractional Nonlinear
           Schrödinger Equation with Generalized Anti-cubic Nonlinearity using
           Conformable Derivative

    • Authors: Husniyah. A. Mohammed; Abdulmalik. A. Altwaty
      Abstract: This work explores Kink soliton solution, periodic soliton solution, and rational function solutions for the fractional generalized anti-cubic (FGAC) nonlinearity in fiber Bragg gratings (BGs). The rational fractional ((D_ζ^α G)/G)-expansion method is employed in conjunction with the idea of a conformable fractional derivative. Due to its nature, the soliton solution looks to have some restrictions.
