in distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. in this paper, the hybrid shuffled frog leaping algorithm (hsfla) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. high accuracy and ...

We study problems of reconfiguration of shortest paths in graphs. We prove that the shortest reconfiguration sequence can be exponential in the size of the graph and that it is NP-hard to compute the shortest reconfiguration sequence even when we know that the sequence has polynomial length. Moreover, we also study reconfiguration of independent sets in three different models and analyze relati...

We extend Reiter’s general theory of model-based diagnosis [Reiter, 19871 to a theory of reconfiguration. The generality of Reiter’s theory readily supports an extension in which the problem of reconfiguration is viewed as a close analogue of the problem of diagnosis. Using a reconfiguration predicate rcfg analogous to the abnormality predicate ab, we formulate a strategy for reconfiguration by...

Reconfiguration is a significant area of after-sales, esp ecially for companies with configurable products. In this paper, the field of reconfiguration is characterised and a framework for reconfiguration is presented on the basis of experiences gathered from Finnish manufacturing companies. Although the state of the practice leaves much room for improvement, reconfiguration is an important bus...

Reliability and speed are two main requirements of a VLSI design. Rapidly increasing device densities cause serious reliability concerns that have been mostly addressed using fault reconfiguration. Another kind of reconfiguration, is functional reconfiguration, which is widely used to provide a better performance by improving the processor-application match. Though fault reconfiguration and fun...

Run-time partial reconfiguration of programmable hardware devices can be applied to enhance many applications in high-end embedded systems, particularly those that employ recent platform FPGAs. Partial Reconfigurable FPGAs allow tasks to be placed and removed dynamically at runtime. These reconfigurable systems have a 2-layer hardware and software architecture that permits a variety of differen...

Reconfiguration is the subject of many investigative activities performed by industrial consortia and collaborative research projects. In the IST End-to-End Reconfigurability (E 2 R) project [1], a perspective on reconfiguration is taken which is not restricted to terminals, but also takes network aspects of architecture into account. Reconfiguration will only be accepted and hence become a suc...

Dynamic reconfiguration is becoming an important requirement of current software systems as they have a trend towards running continuously and updating frequently. The main purpose is to reduce the update cost caused by system shutdown or restart. Controlling the influence of dynamic reconfiguration on system performance is an essential yet difficult issue. Many factors have to be considered an...

Nowadays, manufacturers are faced with severe challenges to response rapidly to changing demands and meet various customers’ needs with respect to production volume and product profile. Reconfigurable manufacturing paradigm was proposed as an advanced manufacturing philosophy to enhance the adaptability and flexibility of manufacturing systems. By physical and logical reconfiguration, Reconfigu...

Hyperreconfigurable architectures can change their reconfiguration capabilities dynamically at run-time. For reconfiguration they use two types of reconfiguration steps: i) in hyperreconfiguration steps they change their ability for reconfiguration, ii) in ordinary reconfiguration steps they reconfigure the actual contexts of a computation within the limits that have been set by the preceding h...
