Evaluating Complex Flexible Processes as Multiple Switching Options
Option models have provided insight into the value of flexibility to switch from one state to another (such as switching a mine or refinery from operating to closed status). More complex flexible processes offer multiple possibilities for switching states. A fabrication facility, for example, may offer options to shift from the current status to any of several alternatives (reflecting reconfigu...
متن کاملFlexible Transmission in the Smart Grid: Optimal Transmission Switching
There is currently a national push to create a smarter, more flexible electrical grid. Traditionally, network branches (transmission lines and transformers) in the electrical grid have been modeled as fixed assets in the short run, except during times of forced outages or maintenance. This traditional view does not permit reconfiguration of the network by system operators to improve system perf...
متن کاملEnhanced Ethernet Switching for Flexible Hard Real-Time Communication
Switched Ethernet arose in the last decade as a means to increase global throughput with parallel switching paths, segment the network and create isolated collision domains, thus reducing the non-determinism of the original shared Ethernet. However the services provided by COTS Ethernet switches are not enough to guarantee real-time communication, which lead to the development of several switch...
متن کاملSustained selective attention predicts flexible switching in preschoolers.
Stability and flexibility are fundamental to an intelligent cognitive system. Here, we examined the relationship between stability in selective attention and explicit control of flexible attention. Preschoolers were tested on the Dimension Preference (DP) task, which measures the stability of selective attention to an implicitly primed dimension, and the Dimension Change Card Sort (DCCS) task, ...
متن کاملFlexible and Efficient Switching Techniques between Scalable Video Bitstreams
In this paper, we first describe a seamless switching scheme for scalable video bitstreams that fully takes advantage of both the high coding efficiency of non-scalable bitstreams and the flexibility of scalable bitstreams. Small bandwidth fluctuations are absorbed by the scalability of the bitstreams, while large bandwidth fluctuations are tolerated by switching between scalable bitstreams. Fl...
