data envelopment analysis (dea) is a method to measure relative efficiency of a set of decision-making units (dmus) which uses multiple inputs and produces multiple outputs. in the conventional dea, crisp inputs and outputs are fundamentally necessary. but the observed values of inputs and outputs in real-world problems are sometimes imprecise. thus, performance measurement often needs to be do...

This paper presents three new systematic approaches for computing coefficient matrices of the Heffron-Phillips multi-machine model (K1, …, K6). The amount of computations needed for conventional and three new approaches are compared by counting number of multiplications and divisions. The advantages of new approaches are: (1) their computation burdens are less than 73 percent of that of convent...

this problem that the world of islam infront of european dynamic modernism is a static unit,has been the base of different hypothesis of the relation of islam and modernity. this issues are repeated that the islamic world be on principle excluded from the history of modern times, because it is bound to a religion which has not traversed the european politico-ideologicalprocess,thus it is a pre-...

the issue of urban decline in city centers and horizontal expansion of the city and its consequences is a challenge in sustainable development of the cities. in this regard, new approaches were shaped to define career planning, urban design and urban environmental quality concerns in new-urbanism pattern. the critical approach to modern urban pattern was formed based on scattered, non-human and...

abstract symptomatic basilar artery stenosis has a poor prognosis. surgical bypasses are technically demanding and of no proven benefit. a new generation of intravascular stents that are flexible enough to navigate the tortuosities of the vertebral artery may provide a new therapeutic approach. our two cases, 57 and 52 year-old men experienced a vertebrobasilar ischemia with repeated vertigo an...

Clustering is the process of dividing a set of input data into a number of subgroups. The members of each subgroup are similar to each other but different from members of other subgroups. The genetic algorithm has enjoyed many applications in clustering data. One of these applications is the clustering of images. The problem with the earlier methods used in clustering images was in selecting in...

In this work, based on experimental observations and exact theoretical predictions, the kinetic scheme of RAFT polymerization is extended to a wider range of reactions such as irreversible intermediate radical terminations and reversible transfer reactions. The reactions which have been labeled as kinetic scheme are the more probable existing reactions as the theoretical point of view. The ...
