Formulation of Time Dependent Bloch NMR Equations for Computational Analyses of Nano Particles in Porous Media

A. A. Adeleke · Journal of Advances in Mathematics and Computer Science · 2016

Nuclear Magnetic Resonance (NMR) has been very useful in the study of pore size distribution of porous materials and in molecular recognition. Important properties of the porous media have been shown to be very much dependent on the T1 and T2 relaxation times. The NMR transverse...

A Proposed Method for Numerical Integration

Felix O. Mettle, Enoch N. B. Quaye, Louis Asiedu & Kwasi A. Darkwah · Journal of Advances in Mathematics and Computer Science · 2016

The main objective of this paper is to propose a numerical integration method that provides improved estimates as compared to the Newton-Cotes methods of integration. The method is an extension of trapezoidal rule where after segmentation, the top part of each segment was further...

New Extension of Kannan and Chatterjea Fixed Point Theorems on Complete Metric Spaces

Aleksa Malčeski, Samoil Malčeski, Katerina Anevska & Risto Malčeski · Journal of Advances in Mathematics and Computer Science · 2016

The theory of fixed point is applied in many fields of mathematics as well as in other studies. That is the main reason for producing new results, as well as for generalizing already known theorems about fixed point. This paper considers several generalizations of R. Kannan [1] a...

Transient Solution for Single Server Machine Interference Problem with Additional Server for Long Queues under N-Policy Vacations

S. A. Ojobor & S. E. Omosigho · Journal of Advances in Mathematics and Computer Science · 2016

We consider the transient state single server machine interference problem with additional server for long queues under N-policy vacations. There are M operating machines with two repairmen. The first repairman is always available for serving the failed machines but go on a singl...
