One of the difficulties that goal-oriented requirements analyses encounters is that the efficiency of the goal refinement is based on the analysts’ subjective knowledge and experience. To improve the efficiency of the requirements elicitation process, engineers need approaches with more systemized analysis techniques. This paper integrates the goal-oriented requirements language i* with concept...

Design process is a key process in forming of product’s cost and if we notify to total design we will see all of the effective parameters in design activities. Design process is contented design planning, design inputs, design outputs, design review, design verification, design validation and design changes. This approach will help us to identify the cost parameters for managing, controlling an...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...

We present a set of problem frames specialized to the area of geographic applications. Problem frames describe the elements of common problems, and help a specifier understand and decompose a complex problem into simpler subproblems for which a solution is often known. We provide an overview of the main issues in geographic applications, and present twelve frames that address many of the proble...

The present article argues for what is essentially a return to the functionalist approach to investigation of memory. Two experiments demonstrate that the effects of level of processing depend on scaled meaningfulness of the material and study time. Data from those experiments along with data currently in the literature are then reanalyzed to examine the effect of repetitions. Of particular int...
