Maintenance costs of Information Systems (ISs) are high today and are growing. Part of the costs come from low software quality. The software quality can be measured when it is maintained. By improving the quality of maintenance prone modules future maintenance costs may be curtailed. In this article we will discuss how to measure software quality and we will also present a prototype that has b...

Density functional theory is used to analyze the stability and structural properties of droplets formed by the condensation of a volatile solvent on a soluble fluid particle composed of a fixed number of molecules of a second species with extremely low volatility. Interaction parameters between the species are chosen to ensure that the soluble particle is completely wetted by the solvent. We st...

in most of the multi-criteria decision making problems, it is important to have necessary information about relative importance of each criteria. in this group of problems, weights measure the relative importance of preferences of each criteria in comparison with the other decision making criteria. in this research, the nise method has been used for mapping mean-variance efficient frontier. nis...
