This manuscript discusses the operation of an electrically driven fan for a hybrid-electric propulsion system BAe-146 aircraft. The thrust requirement is fed into integrated cycle and aerodynamic design tool sizing ducted as one main propulsors, podded under wing replacement turbofan engine. electric motor initiated with torque speed requirements dimensional constraints arising from geometry. a...

This paper summarizes the bidding procedures proposed by NEPOOL for the Energy, Reserve, Automatic Generation Control (AGC), and Operable Capability markets. Experience with the Installed Capability market is also described. On October 29, 1997 FERC accepted NEPOOL’s previous filings proposing the implementation of the Installed Capability Market by November 1, 1997, but suspended its implement...

In this research, a Dependency Network Analysis technique has been adapted to assess operability, reliability, and resilience in both operational and development networks, associated with System of System architectures. The architecture is modeled as a directed network where nodes represent either the component systems or the capabilities to be acquired. Links on the network represent various k...

This paper addresses the stability of the switched systems with discrete and distributed time delays. By applying Lyapunov functional and function method, we show that, if the norm of system matrices Bi is small enough, the asymptotic stability is always achieved. Finally, a example is provided to verify technically feasibility and operability of the developed results. Keywords—Switched system,...

We present an operable definition of focus which is argued to be of a cognito-pragmatic nature and explore how it is determined in discourse in a formalized manner. For this purpose, a file card model of discourse model and knowledge store is introduced enabling the decomposition and formal representation of its determination process as a programmable algorithm (FDA). Interdisciplinary evidence...
