the basic models of data envelopment analysis (dea) are designed in such a way that the values of input and output indicators should be identified and known in them. in other words, these models are not used to consider inaccurate, interval, fuzzy, judgment data. in this paper, the aim is to not only review the past researches about the efficiency of the units by interval data and represent the...

the present survey is a correlation study designed to determine extent and type of relation between mid-arm   circumference and weight in order to offer a scale for assumption of weight.   390 healthy, adults who are resident in tehran and between the ages 18-65 were selected from visitors at three   hospital censers at random. input accumulation was carried out by means of a questionnaire and ...

the calculation of rts amounts to measuring a relationship between inputs and outputs in a production structure. there are many methods to measure rts in the primal space or the dual space. one of the main approaches is using the multiplier on the convexity constraint. but returns to scale measurements in dea models are affected by the presence of regulatory constraints. these additional constr...

Data envelopment analysis (DEA) is a non-parametric approach for performance analysis of decision making units (DMUs) which uses a set of inputs to produce a set of outputs without the need to consider internal operations of each unit. In recent years, there have been various studies dealt with two-stage production systems, i.e. systems which consume some inputs in their first stage to produce ...

introduction: the aim of this study was to get to a neurological evaluation of one of the persian music scales, homayoun, on brain activation of non-musician subjects. we selected this scale because homayoun is one of the main scales in persian classical music which is similar to minor mode in western scales. methods: this study was performed on 19 right handed subjects, aging 22-31. here some ...

In this paper we introduce R-right (left), L-left (right) cancellative and weakly R(L)-cancellative semigroups and will give some equivalent conditions for completely simple semigroups, (completely) regular right (left) cancellative semigroups, right (left) groups, rectangular groups, rectangular bands, groups and right (left) zero semigroups according to R-right (left), L-left (right) and weak...

introduction: drug craving could be described as a motivational state which drives drug dependents towards drug seeking and use. different types of self-reports such as craving feeling, desire and intention, wanting and need, imagery of use, and negative affect have been attributed to this motivational state. by using subjective self-reports for different correlates of drug craving along with f...
