Development of downstream operations in the Iran's petroleum industry has always been considered as a necessity in to create more value-added. One of ways to accomplish the misson, especially in the current situation, is exploiting the capacity of petroleum startups. Considering that these companies need to be valued for financing, and since the traditional valuation methods do not provide effi...

in any clinical encounter, an effective physician-patient relationship is necessary for achieving the desired outcome. this outcome is successful treatment, and therefore, the relationship should be a healing one. in addition, in the islamic view, the physician is a manifestation of god’s healing attribute, which is usually undermined in everyday therapeutic communications. yet there are few em...

Hysteresis loop curves are highly important for numerical simulations of materials deformation under cyclic loadings. The models mainly take account of only the tensile half of the stabilized cycle in hysteresis loop for identification of the constants which don’t vary with accumulation of plastic strain and strain range of the hysteresis loop. This approach may be quite erroneous particularly ...

There are situations that Decision Making Units (DMU’s) have uncertain information and their inputs and outputs cannot alter redially. To this end, this paper combines the rough set theorem (RST) and Data Envelopment Analysis (DEA) and proposes a non-redial Rough-DEA (RDEA) model so called additive rough-DEA model and illustrates the proposed model by a numerical example.  

    Dynamic model,   regional economy,   innovation.   This paper presents a normative balance mathematical model of regional economy that contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. A method for estimation of the model parameters by application of parallel computations on multi-processors systems is presented. It is determined the...
