Several database operations may result into the same path. We address the problem of optimal index con guration for a single path. As it will be shown an optimal index con guration for a path can be achieved by splitting the path into subpaths and by indexing each subpath with the optimal index organization. We present an algorithm which is able to select an optimal index con guration for a given path. For the moment we consider a limited number of existing indexing techniques (simple index, inherited index, nested inherited index, multi-index, and multiinherited index) but the principles of the algorithm will remain the same adding more indexing techniques.

The Mathematical Method and Thermodynamic Approaches to Design Multi-Component Refrigeration used in Cryogenic Process Part II: Optimal Arrangement
A refrigeration cycle is a chain of various pieces of equipment including compressors, condensers, evaporators, and expansion devices each of which takes on a particular thermodynamic process duty in the cycle that eventually results in the production of the required refrigeration. The results of optimized mixed refrigerant cycles (MRCs) in Part I show that the configuration of MRC is an eff...

متن کاملReconfiguration of distribution systems to improve reliability and reduce power losses using Imperialist Competitive Algorithm
Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...

Several studies on photovoltaic systems focused on how it operates and energy required in operating it. Little attention is paid on its configurations, modeling of mean time to system failure, availability, cost benefit and comparisons of parallel and series–parallel designs. In this research work, four system configurations were studied. Configuration I consists of two sub-components arranged ...
