This paper aims to determine the variation of the axial displacement in a fixed bar using Finite Difference Method (FDM). The mathematical modeling is derived based on the wave equation and solved by analytically using ...

Variance has been commonly used as risk measure in portfolio optimization since the introduction of mean-variance model by Markowitz. However, the mean-variance model is a quadratic programming model. It takes longer time ...

Research has shown that nanofluids which are engineered colloids composed of a base fluid and nanoparticles have higher thermal conductivity and possess enhanced heat transfer coefficients compared to the base fluids. ...

Different forms of Givens rotations have been proposed and available in the publishing industry. In this paper we derive via Pythagoras and Taylor series expansion to establish a noble ideal on the derivation of Givens ...

This method computed the approximate solution at 2-point concurrently with equidistant block. A code is develop and been compared with the classical Backward Differentiation Formula (BDF) method. The numerical results are ...

Lagrangian relaxation dual function is a technique commonly used to optimize non-convex problems. The difficulty in obtaining a solution method for the dual function is normally due to the function’s non-differentiable ...

The study is about impact of a short viscoelastic rod (or slug) on a stationary semi-infinite elastic rod. The viscoelastic materials are modeled as standard linear solid which involve three material parameters and the ...

The linear optimal diffusion primitives, i.e. MDS matrices, are widely used in block ciphers. In this paper we studied some properties of MDS matrices over finite filed; particularly we proved that MDS matrix does not ...

In this paper, we investigate the applications of two different schemes of Newton-Cotes quadrature method that is repeated trapezoidal (RT) and repeated Simpson’s 31 (RS1) schemes via Half-Sweep Successive Over-Relaxation ...

One of the most popular soliton equations is the Korteweg de Vries (KdV) equation which is usually used to model shallow water waves. The general forms of this equation is given by 06=++xxxxtuuuu where u(x,t) describes the ...
