164 March 2015, Vol. 105, No. 3 Inaugural International Association of Student Surgical Societies Symposium To the Editor: A noteworthy event for global undergraduate surgical education took place when the University of Cape Town Student Surgical Society successfully hosted the inaugural International Association of Student Surgical Societies (IASSS) Symposium. The IASSS is a recently establish...

in this paper, a new spectral-iterative method is employed to give approximate solutions of fractional logistic differential equation. this approach is based on combination of two different methods, i.e. the iterative method cite{35} and the spectral method. the method reduces the differential equation to systems of linear algebraic equations and then the resulting systems are solved by a numer...

The ultrasound transducer generates ultrasounds. It emits them, collects the return echo and allows the ultrasound system to re-create an image that (few people) know how to interpret. The probe and the ultrasound system work together by measuring the liquid component of a tissue, as ultrasounds propagate easily trough the water. On sonography imaging liquids appear black because they are “anec...

in this paper, a numerical solution of an inverse non-dimensional heat conduction problem by spline method will be considered. the given heat conduction equation, the boundary condition, and the initial condition are presented in a dimensionless form. a set of temperature measurements at a single sensor location inside the heat conduction body is required. the result show that the proposed meth...

we introduce and discuss the homotopy perturbation method, the adomian decomposition method and the variational iteration method for solving the stefan problem with kinetics. then, we give an example of the stefan problem with  kinetics and solve it by these methods.

in this paper, a boussinesq equation is solved by using the adomian's decomposition method, modified adomian's decomposition method and homotopy analysis method. the approximate solution of this equation is calculated in the form of series which its components are computed by applying a recursive relation. the existence and uniqueness of the solution and the convergence of the propose...
