The aim of this paper is to demonstrate that the usage of the Bung-Wand-Weber (BWW) Ontology as a theory in method engineering is both feasible and relevant. Weber and his colleagues introduced the BWW Ontology as theoretical foundation for conceptual modeling. In this paper we describe how the BWW Ontology can be used to systematically underpin the development of modeling grammars. Since the d...

in this paper, a robust model presented is developed for hub covering flow problem in which hubs have capacity. this problem has two objective functions converting to a single-objective problem by using weighting method. firstly, the problem will be formulated in a certain case. then, by considering the demand as a non-random variable, it will be modeled by robust optimization. finally, by usin...

in this paper article of “wine” written by kathryn kueny in encyclopedia of the quran, vol. 5, pp. 481-483 is translated and then is surveyed and criticized by using of shiite and sunni jurisprudential, interpretative and lexical books and some of legal articles of case law of iran. the author firstly mentions nature and quiddity of wine and also local situation of building wine, and then he de...

in this paper, firstly by using a mixed linear programming a new model of locating facilities with limited capacity is presented to design a closed-loop supply chain in a multi-product and multi-period mode. then, using a robust optimization approach, the proposed model decreases in non-deterministic expansion. the results show that the proposed model can handle facility capacity in a closed lo...

in this paper technology policy of india which has evolved over the years have been introduced as following: firstly, it is selective and seeks to protect local technology. secondly, it seeks to reduce to direct costs and individual costs of technology imports by regulating the royalty rates, other payments, the duration and restrictive clauses. thirdly, it discourages technology imports throug...

this paper presents a different explanation and perception of essence and function of the “national security strategy document”, based on general framework of practical and interpretive approaches to the philosophy of politics and social science. then based on the already concept, it is explained that, “national security strategizing” , and shaping of an integrated and unitary reading and inter...

in this paper, our purpose is twofold. firstly, the tensor andresiduum operations on $l-$nested systems are introduced under thecondition of complete residuated lattice. then we show that$l-$nested systems form a complete residuated lattice, which isprecisely the classical isomorphic object of complete residuatedpower set lattice. thus the new representation theorem of$l-$subsets on complete re...

cardiac laceration from blunt thoracic trauma is not a common presentation. the rate of mortality due to this injury is very high since it is not diagnosed and treated immediately. in this study, we present the case of a 65-year-old man with blunt cardiac trauma, causing right atrial rupture and pericardial tamponade. successful management of this patient was firstly done with initial pericardi...

in this work firstly zno nanoparticles were synthesized via a simple precipitation method. at the second step titanium dioxide and silicon dioxide shell were synthesized on the core. for preparation zno-tio2-sio2 the sol product was calcinated at 500 ºc for 2h. properties of the product were examined by x-raydiffraction pattern (xrd), scanning electron microscope (sem) and fourier transform inf...

responding to ruth mcdonald’s editorial on the rise of leadership and leadership development programmes in healthcare, this paper offers three arguments. firstly, care is needed in evaluating impact of leadership development, since achievement of organisational goals is not necessarily an appropriate measure of good leadership. secondly, the proliferation of styles of leadership might be unders...
