The motivation of this paper is to propose such equitable method for ranking all decision making units (DMUs) in dynamic Data Envelopment Analysis (DDEA) framework. As far as we are aware there is not more studies in dynamic DEA literature. What's more, in such cases the best operating unit is important to be sampled for the others in under evaluated time periods. However, in this special conce...

some of the important mechanical loads in the civil and military industries are variable speed and power and their efficiency. mechanical coupling of two different electric motors is suitable for these types of application. using this technique reduces energy consumption of submarine’s motion system and submarine range would be increased. but the use of this technique requires a complex control...

In this paper the numerical simulation of flow field in the new design dynamic cyclone separator is investigated. The effects of different geometrical parameters such as impeller diameter, number of vanes, length and the location of impeller is investigated. The Reynolds averaged Navier–Stokes equations with Reynolds stress turbulence model (RSM) were solved. The Eulerian-Lagrangian computation...

This chapter takes a dynamic view in a double sense: how do different forms of organization develop in time, and how do they perform with respect to innovation? On the basis of a theory of organizational learning, an attempt is made to explain the relative advantages of large, integrated forms and disintegrated forms of organization (networks). Disintegration and differentiation are required fo...

We consider a model in which production of a downstream good requires access to an excludable upstream resource owned by a vertically integrated firm. The quality of the resource depends on an investment made by the owner and impacts the demand curve in the downstream market. Under open access, the owner must share the resource with downstream competitors at a regulated tariff, determined after...
