On the Handling Qualities of Two Flying Wing Aircraft Configurations
Aerospace, 2021 The coupling of the longitudinal and lateral stability modes of an aeroplane is considered in two cases: (i) weak coupling, when the changes in the frequency and damping of the phugoid, short period, dutch roll, and helical modes are small, i.e., the ...

Secure quality of service handling: SQoSH [PDF]
IEEE Communications Magazine, 2000 Proposals for programmable network infrastructures, such as active networks and open signaling, provide programmers with access to network resources and data structures. The motivation for providing these interfaces is accelerated introduction of new services, but exposure of the interfaces introduces many new security risks.
