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...

the main purpose of this paper is to develop an effective and efficient promotion mix model and determine the share and value of each of the underlying variables in the promotion mix in accordance with the marketing and promotional goals and strategies of a firm. the review of earlier studies indicate that the promotion mix components such as competitor’s advertisement, public relation budget, ...

This study investigates whether four types of achievement goals-mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance-influence effort and intrinsic interest at work. Cross-lagged panel analyses were applied to data from a two-wave survey conducted on 57 newly hired Japanese police officers. The results showed that performance-approach goals had significant positi...

In this paper, first we examine the usual treatment of temporal information and we recall the main features relative to the temporality analysis in texts. Then we deal with the formal representation of calendar expressions, and we provide a functional approach, based on a categorical representation of ordinals. Finally, an ongoing application providing a help for the reading of long biography i...
