    Realization of Convergence Splines/ NURBS of Higher Order Stability in Isgeometric Analysis

    Mohd Taib Shatnawi*

    DOI: 10.37421/ 2168-9679.2022.11.480

    Conventional B-splines lack the capacity of local refinement that is required in order to realize ideal convergence order in genuine applications. The challenges with the isogeometric approach include the need to develop an alternative mathematical approach of higher-order equations proven to converge to the shape interface. The main purpose of this study is to determine the realization approach for isogeometric structure in convergence splines/NURBS of distinctive nature of higher-order stability. The basis for this realization approach (i.e. convergence splines/NURBS of higherorder) for B-Spline is degree (order) of realization as used in B-Spline theory. In this approach, the converging (C) order of the basis functions is elevated. An ideal (new) isogeometric structure (i.e. curve or mesh) in convergence splines/NURBS of higher-order stability for improved local refinement has been realized. It is clear that when the order C is enhanced (i.e. realized), converging number n must also be enhanced (i.e. realized) by the equivalent amount of degree. In the process of order enhancement (i.e. the order realization), the stability of every knot value is elevated. Order realization initiates by replicating present knots by the equivalent number as the increase in converging order. In this, every knot vector value is elevated by one point. In line with this, the amount of control points and the basic functions are boosted or amplified from 8 to 13. The refined control points computed was improved where the convergence of higher-order was realized.

      An Interior-Point Method for Nonlinear Constrained Optimization Problem with Trust-Region Mechanism

      Bothina El-Sobky, Gehan Ashry* and Yousria Abo-Elnaga

      DOI: 10.37421/2168-9679.22.11.479

      We introduced an algorithm to solve a Non Linear Constrained Optimization (NLCO) problem in this paper. This algorithm follows Das’s idea of Newton’s interiorpoint method that uses a diagonal matrix of Coleman and Li for NLCO problems. A Trust-Region (T-R) mechanism is used to globalize the algorithm. This algorithm follows Byrd and Omojokun’s idea of step decomposition. It is a successful idea to overcome the difficulty of having an infeasible quadratic T-R sub problem and converts the quadratic T-R sub problem into two unconstrained T-R sub problems.

      A global convergence theory of the algorithm is studied under five standard assumptions. This algorithm is different and maybe simpler than similar ideas such that the global convergence theory is not depending on the linear independence assumption on the gradients of the constraints.

      Some numerical tests are stated to indicate that the algorithm performs effectively and efficiently in pursuance.

          Time series modeling and forecasting has ultimate importance in various practical domains in the world. Many significant models have been proposed to improve the accuracy of their prediction. Global warming has been a big challenge to the world in affecting the normality of the day to day economic and non-economic activities. It causes far-reaching weather changes, which are characterized by precipitation or temperature fluctuations. Rainfall prediction is one of the most important and challenging tasks in the recent today’s world. In Kenya unstable weather patterns which are associated with global warming have been experienced to a greater extent. The objective of this study was to modeled rainfall patterns in Kenya by use of Bayesian Vector Autoregressive (BVAR). To achieve this objective, the data was first statistically diagnosed using Augmented Dicker Fuller and Granger Causality test. The BVAR model was developed using multiple regression analysis in a system of equations. The model sensitivity was performed using confusion matrix and the F-test was used to compare the variances of the actual and forecasted rainfall values. After the first differencing the data was found to be stationary where Augmented Dicker Fuller (ADF) test was statistically significant with P-values <0.05. The Granger Causality test found that; temperature, atmospheric pressure, wind speed and relative humidity influenced the rainfall time series models in all the regions. The model sensitivity was performed using confusion matrix. The BVAR model developed was statistically significant (R2=0.9896). The sensitivity of the model was 82.22%, making it appropriate for forecasting. In conclusion the Bayesian Vector Autoregressive model developed is suitable and sensitive for forecasting rainfall patterns.

          Approximate Solution to First-order Integro-differential Equations Using Polynomial Collocation Approach

          Ganiyu Ajileye* and F.A. Aminu

          DOI: 10.37421/2168-9679.2022.11.486

          In this study, power series and shifted Chebyshev polynomials are used as basis function for solving first order volterra integro-differential equations using standard collocation method. An assumed approximate solution in terms of the constructed polynomial was substituted into the class of integro-differential equation considered. The resulted equation was collocated at appropriate points within the interval of consideration [0,1] to obtain a system of algebraic linear equations. Solving the system of equations, by inverse multiplication, the unknown coefficients involved in the equations are obtained. The required approximate results are obtained when the values of the constant coefficients are substituted back into the assumed approximate solution. Numerical example are presented to confirm the accuracy and efficiency of the method.

          Displaying Nonlocal Conduct in Pandemics by Means of a Response Dispersion Framework Consolidating Populace Development along an Organization

          Sadiya F. Shaikha*

          DOI: 10.37421/2168-9679.2022.11.489

          The episode of Coronavirus, starting in 2019 and going on through the hour of composing, has prompted reestablished interest in the numerical displaying of irresistible sickness. Late works have zeroed in on fractional differential condition (PDE) models, especially response dispersion models, ready to depict the movement of a pestilence in both reality. These examinations have shown commonly encouraging outcomes in portraying and anticipating Coronavirus movement. Be that as it may, individuals frequently travel significant distances in brief timeframes, prompting nonlocal transmission of the sickness. Such virus elements are not very much addressed by dissemination alone. Conversely, customary differential condition (Tribute) models may effortlessly represent this way of behaving by thinking about divergent locales as hubs in an organization, with the edges characterizing nonlocal transmission. In this work, we endeavor to join these demonstrating standards by means of the presentation of an organization structure inside a response dispersion PDE framework. This is accomplished through the meaning of a populace move administrator, which couples disjoint and possibly far off geographic locales, working with nonlocal populace development between them. We give scientific outcomes showing that this administrator doesn't upset the actual consistency or numerical well-posedness of the framework, and check these outcomes through mathematical tests. We then utilize this strategy to recreate the Coronavirus plague in the Brazilian district of Rio de Janeiro, exhibiting its capacity to catch significant nonlocal ways of behaving, while at the same time keeping up with the benefits of a response dissemination model for portraying neighborhood elements.
