In order to maximise service interoperability, it is of course recommended to reuse concepts and classes as much as possible by adhering to upper-level domain ontologies, but this is not a requirement in SADI and concepts can be manually mapped to those appearing in supporting service ontologies, if required.
Recently, the PMIPv6, designed by the IETF, has become essentially a derivative of MIPv6 in terms of signaling and reusing many concepts such as the HA functionality.
"Most people never knew about all the reuse concepts proposed by various architectural firms," she said.
Fig. 3 Express-G Diagrams showing the reuse concepts for geometry (a) and type properties (b).
The development of conceptual models using the Unified Modeling Language (UML) facilitates the representation of modeled concepts and allows software developers to directly reuse these concepts in the design of a software system.
However, this customer orientation may lead to inefficient performance, due to a lack of mechanisms to reuse proven concepts, designs and production facilities, as well as an absence of feedback mechanisms from products in use and service.
"But I think everyone is more sensitive to the reuse concept now".
The reuse concept behind the shuttles, of course, allows the three main engines, 21 tons of high-precision machinery, to fly over and over.
This strategy is designed to make better use of the available channels by taking advantage of the spatial reuse concept.
Spencer Evans, a 29-year-old Los Angeles native who works with Ms. Tai, says his goal is to introduce the reuse concept into the tight-fisted Broadway theater market, where stage sets are built and trashed all the time.
