A Numerical Hybrid Block Integrator for Solving First Order Oscillatory and Exponential Differential Equations A.M. Alkali Binta Abubakar Dahiru Umar Dunama William Volume 2, Issue 3, Pages 1-9, July 2023 In this paper, a numerical hybrid block method is designed for the solutions of oscillatory and exponential first-order initial value problems in ordinary differential equations (ODEs). In deriving the method, we used the method of Collocation and Interpolation of power series approximation to generate a one-tenth-step continuous Block scheme. The convergence properties along with the stabil... Read More Article DOI: doi.org/10.47001/ICJES/2023.203001
Determination of Activation Energy of Amorphous to Crystalline Transformation for Bi2S3 chalcogenide Glasses by Using Isoconversional Methods Abdullah Omar Ali Tawfik Mahmood Mohammed Ali Mehdi Ahmed Dabban Volume 2, Issue 3, Pages 10-20, July 2023 In this work, the structure and kinetics of the crystallization reaction of amorphous Bi2S3 chalcogenide glasses were investigated using powder X-ray diffraction, scanning electron microscopy (SEM), and differential scanning calorimetry (DSC) techniques under non-isothermal conditions with different heating rates (10-30 K/min). The DSC crystallization data is analyzed using the isoconversion... Read More Article DOI: doi.org/10.47001/ICJES/2023.203002
