Foundation students in engineering should have a strong basic in calculus. The aims for this study are to investigate the level of mathematical thinking among students in solving calculus problems and to reveal the ...

The continuous stretching surface heat transfer and flow field problem has many practical applications in industrial and technology. Some of the application areas are hot rolling, paper production, metal spinning, drawing ...

Solving fuzzy equations has long been a problem in fuzzy set theory. Recent study states that standard analytical techniques like Buckley and Qu method are not suitable for solving fuzzy nonlinear equations where the ...

The most prominent method for solving systems of nonlinear equations is the Newton’s method, which required computation of Jacobian matrix and solving system of n -linear equations in each of the iterations. Jacobian mostly ...

We are developing an analytical model for determining the dispersion curve of the folded waveguide traveling wave tube (FWTWT). A typical variation of the electric field at a particular time, shows that the electric field ...

Many engineering problems can be modeled by ordinary differential equations (ODEs). These problems can be solved by using various methods. In this paper, we will use the Runge-Kutta method of order four (RK4) to solve ...

A planar curve called Generalized Log Aesthetic Curve segment (GLAC) has been proposed using the curve synthesis process with two types of formulation; ρ-shift and κ-shift. Both methods were carried out by extending the ...

One of the rituals during pilgrimage is the ‘Tawaf’, that is circling around the Ka'aba seven times each and for a number of times. These are among the ‘problems’ faced by pilgrims in the Hajj season when individual or ...

An in-house tsunami simulation model TUNA is enhanced to incorporate a particle-based transport-deposition module to perform simulations of drill cuttings transport and deposition subject to tides, storms and tsunamis. A ...

prepared by powder metallurgy technique. Dry sliding abrasive wear behaviour of the composite was tested and compared with pure aluminium. The sliding wear test has been conducted in a pin-on-disc testing machine. The ...
