A usability evaluation technique to evaluate user interfaces is introduces. The technique is effective and affordable for small manufacturing companies. By using this technique, an integration of users' feedbacks and some usability concepts, a product can be 3 times easier to use among potential users and more than 5 times easier to use among motivated users. In addition, the technique can be i...

Software product lines are families of products defined by feature commonality and variability, with a well-managed asset base. Recent work in testing of software product lines has exploited similarities in different development phases to reuse shared assets and reduce test effort. The use of feature dependence graphs has also been employed, and there has been some work that aims to reduce dupl...

The DNA microarray is an important technique that allows researchers to analyze many gene expression data in parallel. Although the data can be more significant if they come out of separate experiments, one of the most challenging phases in the microarray context is the integration of separate expression level datasets that have gathered through different techniques. In this paper, we prese...

this paper presents an overview of new approaches in rapid product development in production networks from design points of view. the manufacturing industries are changing their focus to global sourcing as a means to improve performance and enhance competitiveness. some partnerships created with this strategy improve product development through collaborative design. with the advent of e-commerc...

from the beginning of emerging concept of supply chain, a variety of strategies or paradigms have been developed for supply chain organizations .the most important paradigms are four main paradigms, namely the lean, agile, resilience and green. each of these paradigms has advantages and disadvantages. using the benefits of this paradigms and the plan to eliminate the disadvantages of each parad...

we reduce the two phase stefan problem with kinetic to a system of nonlinear volterra integral equations of second kind and apply newton's method to linearize it. we found product integration solution of the linear form. sufficient conditions for convergence of the numerical method are given and their applicability is illustrated with an example.

in this paper, we develop a numerical resolution of the space-time fractional advection-dispersion equation. we utilize spectral-collocation method combining with a product integration technique in order to discretize the terms involving spatial fractional order derivatives that leads to a simple evaluation of the related terms. by using bernstein polynomial basis, the problem is transformed in...
